Abstract
Abstract The invention embodies a tool holder in which a spring plate is slidably mounted and which plate includes oppositely disposed spring portions, one of which portions is formed with a seat adapted to receive a cutter element in projecting relation thereon and the other portion having bearing engagement against the cutter element when disposed on the seat. A slide member is also slidably mounted in the tool holder for movement into and out of camming engagement with said spring plate for tightening the cutter element between said spring portions and a screw threadably engaging said tool holder and said slide member is provided for manually turning thereof in opposite directions for moving said slide member into and out of said camming engagement.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
200 words
A tool holder for mounting a cutter element consisting of a metal block having a longitudinally extending slot in one face thereof and an inwardly and downwardly extending recess at one end, a spring plate slotted longitudinally to provide upper and lower spring portions, said spring plate be slidable mounted in said slot in said block to dispose said spring portions in projecting relation forwardly of said block, said lower spring portion being recessed to provide a seat its forward end adapted to recess a cutter element in forwardly projecting relation, said upper spring portion extending partly over said cutter element when positioned on said seat, a slide mounted in said recess in said block and movable into and out of impinging engagement with said upper spring portion, and screw means mounted in said block and having threaded engagement at one end with said slide and with said block at the other end and adapted to be turned in one direction for moving said slide in one direction against said upper spring plate for securing the cutter element on said seat and to be turned in the opposite direction for releasing the cutter element from secured position on said seat.
