Paces Races Restoration Progress February 2
I will remove the frame casting from the left end of the cabinet. This contains the crank that drives the pump bellows and has some tensioning sprockets to keep the ladder chain tight.
The left frame holds a series of linkages and provides a mounting point for some of the mechanical parts. The pump bellows on the right are driven by connecting rods to the crank turned by the sprocket and chain on the left. The small wooden wheels provide support for the ratchet bars that move the horses.
The crank is more obvious with the connecting rods dangling to the right.
There are a series of linkages mounted to the frame. This one is a lockout that prevents the next game from being played while the current game is in progress. Again, it is laid out on the box with the parts in the same location as in the game. The drawing on the paper shows where the mounting bracket is and shows the bolt and lock washer are on the outside of the bracket on the frame.
First indication of a problem is the angle of the sprocket in the center top. This sprocket drives the chain that runs the length of the game. The guide below the sprocket provides a way to tension the chain.
The source of the wobble on the sprocket is obvious. The sprocket and the rod it is on was brazed onto the end of the crank. Unfortunately the location of the right part of the rod was not in line with the rest of the crank, resulting in a significant wobble. It needs to be redone.
The pillow blocks show the wear of the crank, and the blocks having to support the parts of the crank with the most wobble show extreme edge wear. The ladder chain also shows wear on the edges as a result of the sprocket wobbling.
