There are nine overhanging assemblies in each of the adders on the long row of assembly tables, on the right hand side of the image above. They look like pairs of fingers reaching out perpendicular to the left hand top support bar of each adder and protruding left of each adder in the direction of the line of men working on them, the line starting from the centre of the image and ending at the far wall near the top right corner. These pairs of fingers are easy to see on the nearest three adders on the right hand side of the image and the men working on these adders have their right hands on or near these pairs of fingers. A small rod will be inserted between the tips of each pair of these fingers, which act as fulcrums for the storage screw locking levers. These overhanging assemblies are typical of the Longchamps adders. Nine of them can be seen in the image of a complete Longchamps adder below, above and rearward of each of the nine pulleys right across the front mid section of the adder. Back to the image above, these overhanging assemblies are at the front of the adders, near the men working on them and on the right hand side of the nearest adder assembly tables, you can see the nine rear end support pillars standing which will support the rear end of the nine storage screws yet to be installed. The storage screws are long tubular devices which are a mechanical form of memory described in the Brough Park Newcastle Upon Tyne 1936 section pages accessible by clicking on the image above and scrolling up to that section. Some of the nine storage screws are visible in the complete adder image below, behind the nine pulleys across the front mid section of the adder.
On the nearest two adders in the image above, underneath the finger like assemblies to the left of the supporting bar, you can see some of the the storage screw drive pulleys already in place clearly indicating they are Longchamps adders, as I have not seen this drive arrangement in any other adders. These drive pulleys can be seen in the image below across the front of the adder, two larger pulleys on the left hand side with seven smaller pulleys on the right. All the men working on the right hand row of tables, are working on this area of the Adders. The image below shows one of the Longchamps adders fully assembled and installed in the Longchamps machine room. There is a full sized version of this image in the Photo Gallery of this website and the associated page contains a description of the adder. To view this, click on the image above, scroll to the bottom of the page and select the Previous page button in the navigation bar, then scroll down in the index to the section with a title starting Longchamps Paris 1928 ... and finally select the image thumbnail corresponding to the image below. I do not know if I have convinced you dear reader, that the adders being assembled in the image above are the same as the Longchamps adders like the one shown in the image below, however I am totally convinced. As the Longchamps system for France was unique, in that it was the largest Julius Tote system installed at the time with 273 terminals requiring the largest of adders, only to be later surpassed by the White City London Julius Tote with 320 terminals utilising a different model of adders, I have not seen any evidence that the Longchamps type of adders were used in any other installation.
With the highest level of confidence possible, regarding the Adders in the image above being built for Longchamps, a system that commenced operation in 1928, I think it is safe to write that the photograph shown in the image above must have been taken inside the Alice Street Newtown factory, as this factory had been in operation since at least 1917, probably earlier, and the Alice Street Newtown factory address continues to appear in the Sydney phone books until November 1933. In 1934 the Sydney phone book gives the address of the Automatic Totalisators Limited factory as Chalmers Street in the Sydney CBD.
As the image above shows the adders being assembled for Longchamps racecourse in Paris, France, I have included the following Trove archive Newcastle Morning Herald and Miners' Advocate article, which demonstrates the significance of the French contract for Australia, which involves multiple racetracks. It is the largest Austral-French commercial transaction at the time.

The French order meant considerable design work, as now, for the first time, the Adders were to be divorced from the Indicators. The Adders had to have a capacity of a minimum of 273 Ticket Issuing Machines through a Distributor connected to one Escapement Wheel, over 35 Escapement Wheels where needed on each Adder. The Adder design was a feat of mechanical engineering, all values and transfers being mechanically linked. The Ticket Issuing Machine design also was a remarkable piece of engineering and saw the introduction of a machine to sell both Win & Place tickets from the one machine. This was a big step forward and proved to be one of the main features for many years to come. The equipment for Longchamp was manufactured in the factory at Alice Street, Newtown, N.S.W. except for the Ticket Issuing Machines, which were made in Paris under supervision.
TOTALISATOR FOR FRANCE
Universal Automatic Totalisators, Limited, Sydney, has contracted to instal at Longchamps totalisator machines of the type used in Sydney.
At first they will be operated by Australians to allow of a French staff being trained. This, together with the contract signed by Mr. Bethell on behalf of the same company last month to instal totalisators at 16 French racecourses is the largest Austral-French commercial transaction yet effected.(Emphasis added)
Frederick Wilkinson, who was the Automatic Totalisators Limited State Tote Manager and worked for the company for 30 years including the duration of this factory and the following one in Chalmers Street in the city, lived in Paris for 4 1/2 years working on the Longchamps project according to his son Rudolph Wilkinson. Rudolph also indicates that the Longchamps system was one of several to be installed in France as indicated above and that Frederick married Dorothy Watt during his time in France.
A Longchamps mechanical shaft Adder
The pulleys mentioned as being visible in the Adders being assembled in the image at the top of this page, are seen in the image above as the facing nine shiny pulleys, half way up the adder, which are above the row of black drive shaft pulleys. There is a good view of one of the constituent shaft adders and its associated storage screw in this image. The horizontal tubular device, that crosses the post with the number 5 on it, at the top of the Adder, is a storage screw. The right hand end of the storage screw is attached to an assembly that is an electromechanical shaft adder. There is a second storage screw and shaft adder behind the one visible at the top, which obscures the one behind. The main thing in view of this visible shaft adder at the top are some of the escapement mechanism solenoids which are activated by impulses from the TIMs (Ticket Issuing Machines) via the scanners, which today would be called TDMs (Time Division Multiplexers). The top of the shaft adder where the adding shaft is with its escapement wheels and epicyclic gears, is not in view as it has a permanent dust cover over the top. There are 9 storage screws and associated shaft adders in the equipment mounted below this level of the adder, which are mounted perpendicular to the one on top, with their associated 9 shaft adders at the rear of the assembly out of view of the image. The number 5 on top of the post indicates the runner number for which this complete adder is accumulating bets.
As with other images of these early factories, the image at the top of this page reveals how primitive working conditions were in those days. It is a long time to come before people start to think about posture and OH&S issues in general. There are many heads craned downwards, it gives me a headache looking at them! I do not think that any of the workers in this photograph, or any other workers of the time or their management would have considered the limited body positions that a worker can assume while standing without causing health problems or the considerable muscular effort keeping the body upright reducing blood supply in loaded muscles. Something in the order of half a century had to elapse before industry started to take these concerns seriously, driven by the cost of non compliance and even then there was resistance to the adoption of OH&S in the culture of organisations.
The floor in the bottom left of the image of the factory at the top of this page, looks as though it has a foundation of bricks overlaid with something like bitumen. The floor looks very old and as if it has had significant wear, as the bitumen like surface has a significant area where it has peeled off, leaving the bricks exposed. Perhaps it used to be a road! The larger benches on the left are of a solid purpose built construction and look like they have had a considerable working life. The assembly tables the adders are on seem to be a quick construction made out of boxwood. The long exposure time of these old photos is evident as a couple of the people in this image have moved during the exposure time causing them to appear blurred. There is silver nitrate blemishing visible mainly in the bottom right of the photograph, not bad really considering that this photograph was in the order of 90 years old when it was scanned.
