Harringay Greyhound Stadium Totalisator

Charles Norrie

With Tannoy loudspeakers and a strongly period atmosphere, the little Harringay Greyhound Stadium seemed sadly on its way out, and in fact was shortly to close. More popular dog tracks were going in for lots of shiny restaurants and champagne — Harringay had beer and hot potatoes and, but a modest enclosure for the "nobs". A small party from GLIAS joined the tiny crowd of mainly older people, quiet and orderly, at an evening meeting on Monday 16 March 1987. Dogs, mechanical hare and the starting traps were all of great interest and could be inspected at close quarters, but the main attraction was the Julius patent totalisator, the subject of this article, and now, alas, along with the stadium, no more. Before the track closed in September 1987 we made several visits to record the totalisator, installed in 1930, and electromechanical machine of intriguing design used to operate the tote, and in use throughout virtually all the life of the course.

The tote is a form of betting which pits the bet of an individual against the collected bets of all others, and hence differs from fixed odds in which the individual bet is against the opinion of a bookmaker. Simple as the concept is, designing a method for operating a tote effectively within the constraints of the numbers attending a race course and the frequency of races is demanding.

In a series of patents in the first 40 years of the 20th century, the Australian inventor George Julius designed a number of machines that made large scale tote betting feasible, accurate and rapid. In the United Kingdom Julius's machinery, supplied by Automatic Totalisators, was applied to greyhound racing, a sport introduced from America in the 1920s. The machinery at Harringay reflects Julius's 1920s patents but not those from the '30s, and such modernisation as there was (notably in the odds calculation and display machinery) was entirely different.

George Alfred Julius, knighted in 1929, was born in Norwich, England, in 1873 and was taken by his parents to Ballarat, Australia, in 1884, his father securing the position of archdeacon there 1. In 1890 the family moved to Christchurch, New Zealand, and here Julius obtained a BSc in mechanical engineering at Canterbury College in 1896. That year he was employed as an assistant engineer on Western Australian railways, and in 1907 moved to Sydney, as an engineering consultant, but with the right of private practice. His first UK patent (confusingly still giving his location as New Zealand) for counting machinery 2 was to be followed by nearly 20 others stretching through to the early 1940s, which progressively improved and augmented his original invention, finding practical application in automating the tote at Australian horse race courses. The major intention of these patents was to permit an increase in the rate at which bets could be placed, improve the display of betting information and increase the security of the apparatus.

The first machine was installed at Ellerslie Racecourse in Auckland, New Zealand, in 1913, and an improved apparatus was then extensively employed in Australia. By 1930, virtually all the elements comprising the equipment at Harringay had been invented.

His totalisator work was a sideline for Julius, and he had a wide ranging career in Australian government and engineering, advising on subjects as diverse as prickly pear, the break of railway gauge and water resource development. He became the first chairman on the Council for Scientific and Industrial Research, as well as leading several professional engineering organisation. He died in 1946.

In the UK the introduction of Julius's totalisator followed the arrival of greyhound racing from the United States in the 1920s, and required the modification of betting law. Proponents of tote betting considered that mechanisation removed many of the moral objections to bookmaking. The Treasury, recognising that a mechanical system would make the levy of the recently introduced and unpopular betting tax convenient and feasible, amended the Suppression of Betting Houses Act, 1853, which Winston Churchill, the Chancellor, did in 1928, describing greyhound racing as an "animated roulette". Nevertheless, the introduction of tote betting was not accompanied by the suppression of bookmakers.

Harringay Park, as it was first called, on Green Lanes, was the second track owned by the Greyhound Racing Association in London, White City being the first. Constructed by Messrs TG Simpson of Victoria Street, London, on the "miniature hills" of the Harringay Dump, comprising spoil left over from the construction of the Piccadilly line to Finsbury Park, the course was opened in late 1927. It was equipped with extensive kennelling and training facilities 3.

The location was convenient to both trams from Finsbury Park and the LMS station at Harringay on the Kentish Town to Barking line (fig1). Anticipating a more mobile clientele, the promoters advertised its convenient parking facilities. Reportedly costing some 35,000 to construct, the stadium could contain about 50,000 spectators. Familiarity with greyhound racing was not great, and the promoters went to considerable lengths to explain the difference between the new greyhound racing, utilising the mechanical hare, and the traditional sport of coursing thought to be cruel. They also sought to promote the social cachet of racing, claiming that "amongst the number of racing enthusiasts are many titled people. The latest recruit is ex-Queen Sophie of Greece, widow of the late King Constantine." Nevertheless the early facilities appear to have been primitive. The intention was to have evening race meetings during the summer months under electric lighting, during which seven or eight races would be held, with between five and eight dogs in each race. Tote machinery was not introduced for some three years after the start of racing at Harringay, and the course was equipped with its Julius apparatus in 1930. The equipment is almost certainly of Australian origin. Julius's firm, Automatic Totalisators, exporting many machines.

The tote machine consisted of five types of interlinked and patented machines, all represented at Harringay, four of which were operational at its closure. They were the ticket issuing machinery, the commutators, the accumulator tables and the display drums. The odds calculating machinery had been disabled, and the type of betting odds display apparatus it used is unknown. Three kinds of bet — win, place and forecast — were supported for a race of six dogs. However, it is important to bear in mind that the machinery was identical for each type of bet, the differences simply resulting from the wiring and the numbers of machine. One minor difference is that odds were not calculated for the forecast bet.

The win bet, the simplest, requires the machinery to accumulate the bets for each dog and an extra machine for the total of all bets — called the "grand total", making seven machines in all. The place machine similarly requires seven machines, a payout being made on either of the first two dogs, the pot being unequally divided between first and second place. A forecast bet requires the better to name the first two dogs no matter which order they come in, and hence requires fifteen machines for each combination and one for the total. Hence for all bets 30 machines are needed. The rapidly increasing numbers of machines required for bigger races led to six being the standard number of dogs allowed. For example, eight dog races (tried at Catford) would need 47 machines. Machines and display drums were designated with engraved and painted plates showing which bet they represented. Thus 4-W meant dog 4 of a win bet and 1-P dog 1 of a place bet, while 3-5 was for a forecast bet with both dog 3 and dog 5 in the first two places. Grand total machines were usually designated G.T.

The first machine, and the only one that potential betters would have any familiarity with, was the ticket issuing and printing machine. At closure there were some 50 operational ticket desks situated at the back of the grandstand, behind wire grills. Each had one operator. At its peak there were about 150 spread round the ground, although the capacity of the commutator machinery suggests that 240 booths were possible. This was not the limit of Julius's ambition. In 1927 he applied to patent an invention for improvements anticipating the use of some 400 to 500 machines 4.

Each machine could issue a ticket for any type of bet, but at only one price. Particular bets were selected by moving a tram type controller handle over an arc and selecting one of the pits corresponding to a bet and depressing the handle (fig2). The movement of the handle caused one of a series of printing plates located on the circumference of a wheel beneath the top surface of the machine to come into position ready for printing. Depressing the handle closed the circuit with the tote machinery. Printing was inhibited and the ticket not delivered until the tote machinery later in the chain was ready to receive the bet, in turn controlled by the commutators in the tote machinery room, a feature claimed as part of the invention 5. This would normally happen in less than a second. The completion of the circuit permitted the ticket machine to issue and eject the ticket, and simultaneously caused a relay to operate on the accumulator tables. The machine delivered a paper ticket denoting the value of the bet, the dog and type of bet and the race number. Hence, a ticket was not printed until the bet had been registered and properly processed.

The need to control betting so carefully results in part from the very uneven nature of tote betting. Because betters receive starting price odds and these will be more clearly known the later the bet is made, the wise better will place his bet as late as possible, and hence the rate of betting grows towards the time of the start of the race.

The machine room was located at the east end of the track behind the main display board, at first floor level (plate 1). On the ground floor was a room containing a mercury arc rectifier, required to provide DC power for the machinery. There was also a workshop with extensive stores of spare parts for the machinery. The machine room consisted of several interlinked units. The main one, about 60ft long and 20ft wide extended to roof height. On the east side were banks of relays, switches and commutators, on a panel about 7ft high and 30ft long. There were also two operator's panels which controlled the machinery. Facing this, against the wooden west wall which constituted the display board, were the display drums. In the middle were three grand total accumulator "tables" for each bet. Each table was about 3ft by 4ft on a strong metal stand. At the south end the disconnected odds calculating machinery was located. These machines were about 12ft long and of similar depth and height. A room to the east, about 40 ft by 40 ft, contained the "individual dog machines" — accumulators for each bet combination. These machines were identical in concept to the grand total accumulators but were arranged in five or six rows separated by walkways, the break between individual dog machines being difficult to determine. The machine room was open, a light metal structure, and the floor was composed of wood blocks.

Wires from each group of ticket machines were gathered together, led down the stands, routed round the outside of the track itself and then into the machine room, emerging at the back of the commutator board — a mass of wiring. Each ticket machine was connected to the machine room by one wire for each bet and a return. For a selected bet a wire was connected to the appropriate grand total and individual dog machines returning via the commutator. In consequence, a bet was not registered until the commutator swept the particular stud, going onto the next stud in sequence and discharging its bet, if any, on the appropriate grand total and individual dog machines.

Each commutator (Plate 2 Fig. 3) serviced up to eight ticket machines, the rotating commutator polling (although this term is not used in the patents) each contact stud in turn. Julius's commutator permitted an economy on relays and circuitry required to drive the accumulator table without significantly affecting the efficiency of the ticketing process, and he claimed this as a particular advantage in his patent. The commutators were arranged in banks, and swept at the same rate by the commutator arms.

The accumulator tables (Plate 3, Fig 4) on which bets were delivered from the ticketing machines were the computational heart of the totalisator. Bets at different values arrived randomly, and the irregular flows were smoothed and summed to produce a steady output to drive the display drums. The accumulator table consisted of a number of hollow spindles or barrels, typically five in the case of the grand total machines. A barrel represented bets of a particular value, but different barrels could be of different values. For example, the unit bet on one barrel could be 2, while several others processed the minimum bet of 20p. Each spindle contained a long spring which was wound up by a betting impulse. These impulses were delivered by a belt driven epicyclic train which permitted the output of several commutator to be recorded — representing many machines. Julius gives an example where a single table of five spindles, with six escapement wheels in the epicyclic train, and seven ticket machines connected to each commutator, processed the output of 210 ticket machines 4 (Plate 4, Fig 5). These epicyclic trains were composed of cogs and ratchets whose rotation was prevented until allowed to move on one position by the relay. The rotation was then transmitted through to the spring. Ratchets could have different numbers of teeth so that different value bets could be processed on the same barrel, the rotation being greater in the case of higher value bets. Allowing higher valued bets to work the higher valued barrels directly reduced wear and tear on the machinery. These epicyclic trains were normally covered with angled aluminium dust excluders.

As the bets were accumulated, they were unloaded at a constant rate (and the spring unwound) by a permissive clutch at the other end of the spindle. The output of this could be either routed to the display drums (where it was loaded onto another epicyclic train) or the output could be used on the epicyclic train of a higher valued barrel. The speed of unloading could be changed simply by moving a handle on the table, and this was necessary when bets were delivered at too great a rate to the table to be unloaded, which caused a trip to operate and a bell to ring, and prevented the issue of tickets. Finally the bets were registered on the display drums (Plate 5, Fig6). In his 1930s patents Julius was to replace the drums by larger numbers of endless belts, but this improvement was never used at Harringay. The drums consisted of large rings parallel to the central spindle of the apparatus, carrying the numbers on the circumference. They would rotate with great rapidity as betting increased, so much so that the operation of the units wheel with the constant forces of stopping and starting Julius's "inertia and vis-inertia" resulted in a modification in which the units wheel remained at zero until betting had finished.

The operation of the rapidly rotating drum wheels vexed Julius considerably, and he commented:

"At the rate at which betting proceeds on a metropolitan race course on a busy day the rate of the rotation of the hundreds drum is so rapid that great difficulty is experienced in reading with any approximation of correctness."

Hence, he concluded:

"It was found impracticable to apply the registration mechanically to all drums and indicators and rely on those drums and indicators to operate on each other in decimal progression in the manner of a revolution counter 4."

At Harringay only the units counter seems to have been disabled in this way, and in the abandoned place drums (see below) the units were not disabled.

To work this complex machine the totalisator required, in addition to ticket sellers, some 16 people. The machine itself was maintained and operated by the chief engineer, Mr Bowler, who had been employed at Harringay 23 years, and his assistant. During the evening they where joined by a team of six whose sole function was to reset the display drums and counters to zero in preparation for the next race. One or two other staff helped in reading the veeders. In the office beyond the machine room, Mr Carrouths the racing manager, was assisted by an accountant who oversaw the duplicated calculation of the payout by his two assistants. Two telephonists where also based here, as well as the quinella, duella machinery operator. Most of the staff were employed for the short period of an afternoon's or an evening's racing. The senior staff where permanent, working on both racing and non-racing days. Mr Bowler would arrive around 10.30 am and his day was taken up with maintenance tasks, unless there were afternoon or evening racing. If the latter, he would not leave until well after the last race. Nor was the job suitable for anyone who wanted bank holidays. Nevertheless, the GRA was considered an excellent employer. The cycle of Tote operation is the same for each race. The best point to begin with is the announcement of the forecast or payout from the previous race. The engineer checks that the veeder and the display drums are correctly set to zero — the latter as a series of 5s upside down will ensure that they are set to zero. The reason for this concern for the drums, whose numbers where rarely used by the public, and not at all by the Tote staff, is that they remain the "legal display". Satisfied, and ensuring that the race number, displayed on an illuminated screen on his race panel, which will be printed on the tickets sold, has been advanced on the control board, he switches the race locks "off", permitting the ticket machines to work. Gradually, superimposed on the background noise of drive belts and pulleys the characteristic sound of bets being processed through the accumulators is heard. This noise grows as the drums begin to turn.

The irregular and staccato rhythm grows towards the start of race. Mr Bowler tends the machine, observing a veeder here, a drum display there. Occasionally, an alarm rings on one of the accumulator tables ,causing a light globe to illuminate. Too many bets have been received on one of the spindles of the accumulator table, and a switch is triggered. It is quickly corrected by adjusting the processing speed of the table, which is not high with the decline in business at Harringay, and resetting a trip. Eventually, when the time of the race is reached a bell is rung, operated by the opening of the traps on the track. Mr Bowler turns the race locks "on" at the control board, freezing any bets that have not been completed, and there is the characteristic sound of the units drums, which have hitherto been disabled turning incrementally into position.

From the point of view of the tote team this has been the quiet part of the cycle. The first activity is recording the veeder counters. These are positioned at many points throughout the machine — beside the display drums, on the odds calculating machinery and on the individual dog machines. These are recorded and taken to the tote office, where they are handed to the calculating assistants who will prepare the forecast. Curiously, the display of the same numbers on a special unit in the office, part of the output of the electronically calculated odds display, is not used at all. Meanwhile, since the end of betting the telephonists have been receiving calls of bets in error, as the Julius machine cannot correct bets wrongly made. These are summarised and formally written on a slate on the wall, and are deducted from the pool for the race. The calculating assistants go to work. The results are written on standardised forms and the erroneous bets deducted. The operator's profit and tax are calculated and also deducted. From the remaining amount the "dividend" or forecast of the winners is calculated, and having satisfied himself, the accountant reads the dividends from the small soundproof Tannoy booth, which broadcasts round the whole stadium, informing the payout booths and betters who can cash in their winning tickets. From the end of the race less than ten minutes has elapsed. Meanwhile in the machine room, when the tote office is satisfied with the figures they have received, the machinery is reset. Firstly, the units drums are reset automatically from the control pane. Then, the resetting team turns the drums back to zero, an operation requiring a surprising amount of manual dexterity, and resets the veeders. Veeders on the individual dog machines and the grand total tables are zeroed. The totalisator is ready for the next race.

With the decline and partial modernisation of Harringay, a considerable quantity of machinery was not in use. Large numbers of ticket issuing machines had been disconnected. Consequently, the commutators they were attached to were not operational, though they remained functionally connected. A complete set of disconnected display drums were still in their original positions. They had a smaller number of counter wheels than the working drums and it is tempting to conclude that they were superseded as business grew.

The most important disconnected machine was the odds calculator, used to compute the instantaneous odds for each dog in the win bets. In his patent for this machine 6 Julius states its utility:

"In the excitement and hurry which precedes a race it is of great importance to offer to the investor an instant statement of the odds available to him."

While this is of importance to the investor, the odds calculation was not a legal requirement, that being the display betting totals on the display drums. The odds calculator consisted of six identical machines made up of two long leading screws at right angles. One of these screws was turned from the grand total machines, the other from one of the individual dog machines by a driving apparatus in front of each machine. As the screw was turned carriages on the screws moved proportionately. The ratio of the distances that each carriage travelled gives the odds. As Julius saw it:

"The problem to which the invention is addressed is to provide a device for indicating the ratio between the "dividend" figure and the "divisor" figure while either or both of those figures are progressively changing so as to represent the quotient for the time being as a simple fraction."

This was achieved by joining the carriages by a quotient arm whose angle represented the odds. This was all that remained of the odds calculator, and in the patent Julius goes on to describe how the arm position is used to provide an output which can be seen throughout the course. Connected directly to a "Selsyn" electric motor, the output can be transmitted to any number of connected display dials round the course. These could be marked either with odds or payout for a particular bet.

None of the display mechanism had survived. The odds calculator had been replaced by a system connected to the tables themselves, in which rotation of a drive shaft was counted by reed switches which were processed to provide an electronic display showing the odds of each dog in turn. These counters were contained in the boxes which could be seen prominently fixed above the tables. The odds calculator permitted a number of sophistications. For example, the effect of a constant proportionate take for operator's overheads or tax could be calculated simply by turning the grand total wheel slower than the individual dog wheels. Place calculations (where first second and third places get different proportions of the winning pot) can similarly be calculated.

Where the machinery was operational it was in excellent working order. It needed to be. Any errors in the computation of payout had to be borne by the company. It was thought that the error rate was "one in a million", but no evidence was given for this figure.

After the course closed the machinery was quickly removed for scrap with the exception of a representative sample which was taken by the Science Museum 7 and is currently in store pending re-erection. That Harringay survived so long is an accident of the GRA's long standing intention to redevelop the site. It simply became too uneconomic to replace the machinery for the short life the replacement would have had. Julius's patents uncannily foresee many of the problems to confront designers in a quite different field — computers 8. It is perhaps surprising that the special problems posed by as simple a concept as tote betting, should require such a wealth of invention to solve. That today the solution is a relatively trivial computer application detracts not at all from Julius's work.
