I have just required a long play unit which is a bit unusual, made by THE CINEMA WORKSHOP LTD 29 Greenfield Avenue, Hanwell, London.
It has a speed reducer motor that was built in the USA, Chicago, by a company called Bodine Electric Company. It is able to reduce or increase the speed automatically as the reel fills up through a series of linkages that you thread the film through and also has a micro switch that senses when the projector is running or stop’s
Once you have this all going it will stop and start automatically with the projector, it takes 2000ft spools or less. The feed spool is very far back, but could easily add a modification, notice the 50ft spool on the feed arm of the projector, to bring the film round at the right angle, a temporary solution.
Does any one know anything about this long play unit, and has any one else got one.
I may be selling this unit through eBay.
Chris.

That looks like a Spondon Spooler from Spondon Film Services. David Adams, now deceased, ran the company. Check with Derann as I think they bought supplies that were left over stock, but I am only taking a guess on Derann. I built my own using 35mm equipment, but is much larger in size, because it uses 35mm carbon arc drive in projector parts.
To ask the question if a machine can handle longer periods of time under these conditions, I would say yes. (1) The machine is running easier without the load of the reels, it merely has to run cooling fan and drive train (gears, belts, sprockets, etc).
However, if you had two machines and two spoolers, I would keep the maximum equal to the projector's capacities. because it allows the machine to take a rest before running it's orginal maximum rating.
Theater machines 35mm can run all day 7 days a week and never break down, providing they are well maintained, oiled, greased, and so on. They have platters which work differently but is the same intent as your spooler.

John,
This is what i find strange about this unit, there is no clutch mechanism, the film runs through 3 guide rollers, one senses when the film is in motion thus turning the motor on, the other two are connected on a pivot arm that swings round to an angle defined by how much film is on the spool, thus controlling the speed of the motor. I am amazed at how well it works, but i would say not many made, in some areas it looks almost home made, but made very well. The actual motor still carry’s the label stating 115A.C. Which is not the case as would have blown on the 240 volt mains we have here. I am 90% sure nothing to do with Spondon, Chip.
I am wondering if not made for a particular projector, as it is very strange with the feed arm so far back, any ideas out there.
Chris.
