With the throttle lever inthe position shown in the illustration the air enters the manifoldin front of the piston valve at the point marked shop air con-nection. From there it flows forward through the 1-in. ironpipe to the front end of the cylinder. The slide valve F beingclosed, the incoming air forces the piston back to the rear of thecylinder, provided, of course, that the chisel bar is in its work- a staybolt breaker l)y making a few changes. It will be necessaryto remove the cable reel and carriage, and substitute a suitablese
