First Claim
Patent Images
1. The improvement in an apparatus for shearing assembly pins in a shell-plug assembly of a lock having a shell with a longitudinal shell axis and a plug with a longitudinal plug axis rotatably mounted therein, by application of a force on said plug parallel to said plug axis, comprising a frame;
- a recess in the frame to receive a first shell-plug assembly comprising said shell and said plug, said recess including shell holding means for holding said shell against movement during shearing; and
plug translation means for translating the plug while the shell is held, the improvement comprising;
a) a holding device for holding a lock housing defined at least in part by a shell of a second shell-plug assembly therein, said holding device being connected to said frame on a side of said recess opposite said plug translation means and in communication with said recess, said holding device including a support for said lock housing positioned to align the plug of said second shell-plug assembly thereof in the path of movement of said plug translation means as it is translated in an advance direction.
