Abstract

463,730. Broaching. LAPOINTE MACHINE TOOL CO., Ltd., and BONNAFE, O. W. Oct. 3, 1935, No. 27331. [Class 83 (iii)] A tool for broaching grooves, slots, or teeth in the external surfaces of metal articles comprises a number of parallel broaching elements a having end portions g located in radial slots e in end plates f carried by a cylindrical holder b. The ends of the holder are recessed at h to receive the end plates which are retained by cover plates i, j. The holder is formed with end slots m which receive keys fitted in one of the slots e to ensure parallelism of the blades. The interior of the holder may be formed with slots for the passage of cuttings. The holder may be secured to a work table s, Fig. 6, and the work piece q held by a spring catch r against a collar on the ram o is forced through the broach by a fluid pressure cylinder v.
