Then by each revolution of the shaft D the disk L, operating against the disk K, causes the feed-screwF to gradually feed the commutator to the cutting-tool f, thus cutting away all imperfections on said segmental commutator-s and leaving the surface even and in properorder to be replaced on the dynamo. It may be found necessary to pass the commutator across the cutting-tool several times before an even surface is attained; but the operation is the same each time, the feeding process being made automatic by disk L operating against the arms 7; of the wheel K.
Having thus fully described my invention, what I claim as being new, and desire to secure by Letters Patent, is
1. In a machine for turning dynamo-commutators, the main shaft D, the cross-head E, secured to one end of the main shaft and provided with the lug e, the guide 0, on which the lug 9 slides, the disk L on one end of the shaft D, having a finger, the shaft F, having a screw-threaded end F working in a screwhole in the bearing 0, the fingered disk K 011 shaft F, and the crank G, all operating substantially as described.
2. In a machine for turning dynamo-commutators, the main shaft D, mounted on 001- umns C 0, means for turning the shaft, the jig N, 011 which the eommutator-sections are fastened, the cross-head E on one end of the main shaft, having the lug e, the guide 0, on which the lug slides, the disk L on one end of the main shaft, having afinger Z, the shaft F, turning in the cross-head E and having a screw-threaded end F, said end working in a serew-hole in the bearing 0, the fingered disk K on shaft F, and the crank G, all operating substantially as described.
3. The casting or cross-head E, having an opening, a shaft F, working in said opening and provided with a screw end which works in a screw-hole in the bearing C, a fingered disk K, the detent-lever H, secured to the casting E and bearing against the fingers of the disk K, and a spring bearing on the under side of said detent-lever, keeping it in engagement with the fingers 713 of the disk K, substantially as described.
In testimony whereof I affix my signature in presence of two Witnesses.
