I found some pictures of an old mechanical football game I once repaired. The mechanisms are quite cool. The game works by coin insert, wich releases 10 steel balls into a elevator mechanism that hoist them one by one up to the hole in the middle of the game. The elevator is operated by a steel rod with a handle that the player will pull. The game works without electricity.
This picture shows the inside workings of the machine (and a lot of random junk that was inside), the ball rail that puts the balls onto the lever mechanism has fallen off. I found that the rails were actually soldered, so the fix was done with just a soldering iron. As this thing was probably made by hand, quite a lot of adjustments was needed to get it to work in a acceptable way. The chains and bearings did get some good lubrication oil.
The picture underneath shows the score mechanism, it needed some adjustments and oil to work in a good way. The rubber band was removed, probably put there by some other fixer that also left the junk inside the machine.
Here is a slideshow for you with clean pictures!
