Timer help

[cackhanded]

I purchased a bar billiards table here in San Antonio, Texas a little over a week ago. The gentleman I bought it from said the timer did not work. I've cleaned it up and oiled everything up. The timer runs for about 20 minutes. I think there is a bolt missing because if I don't hold the coin, it slides around. Would love any help.

Hi,

Looks like the clock is basically working if it runs for 20 minutes. It looks in good nick and the weak point main driving cog may have already been re-bushed from the look of it.

The clock is missing the spring and thrust bolt (piston) that holds the coin (and controls the size used) and allows the coin to drop when the handle is pulled. I may be wrong but is that what is lying under the handle bar in the picture?

The piston goes through the hole just to the right of the red mark on the right hand side of the clock (handle towards you). The little piston is held on place by the leaf spring which is anchored in the hole about two inches further along the handle bar. Pulling the handle, the head of the piston makes contact with the angled aluminium plate on the clock frame which pushes it across against the spring and exposes a slot in the piston that allows the coin to drop.

I'll post a couple of pictures after brekkie.

Re oiling, use a very light fine oil on the clock moving parts and I use graphite spray on the bar sliders. Don't smother the clock in thick stuff or silicone spray as it adds resistance and attracts dust.

You can make the clock freeplay and bypass the need for a coin for the time being by inverting the coin latch on top of the front of the handle bar the front of the clock. The latch is held in place by two bolts and springs.

One point to note is that the clock tensioner screw on the left is not holding the clock in place against the driving bar and preventing it from sliding left if the hold screw comes loose. If that happens and the screw is not in place to prevent the clock from coming unattached to the driving bar, you will likely destroy the main driving cog on the clock if the driving bar flies uncontrolled. If you want to work on the clock mech then cock the handle bar against one of the non return latches before freeing the clock.

Thanks for the help. Is there somewhere I can get a coin release spring? Is there anyway you can point out the clock tensioner screw?

The clock tensioner screw mounting is sticking up on the left of the clock body as you look at it from the handle. The screw should be adjusted and locked just touching the clock so that the clock cannot slide away from the driving rack if the securing screw on the base of the clock comes loose.

You should be able to manufacture a spring if you have a redundant old wind up alarm clock (or find one at a boot fair). The piston with its groove can be turned.

Sorry I was moving and didn't have my table set up. I can't find what you said I was missing. The spring and thrust bolt. I'm in the US btw
Is there a site that sells these. I found billiards balls but shipping to US is killer.

Thanks for the help sav. I couldn't find anything like that here. I ended up putting a zip tie through the first hole and over the top. Working great when I drop the coin in. Now just trying to figure out how the bar connects to the timer and which way it goes.
