Abstract
551,551. Broaches. LAPOINTE MACHINE TOOL CO., Ltd. (Lapointe Machine Tool Co.). April 30, 1941, No. 5621. [Class 83 (iii)] A broach, particularly for sizing holes of any shape in machine parts, has a pilot 20 followed by, first a series 21 of cutting elements of gradually increasing diameter, then a series 22 of equal diameter sizing members which may in some cases be omitted, and finally a series 23 of stripping members which have both front and back cutting edges 40. 41 and which cut in both directions of movement. The cutting and sizing teeth are of similar form and are relieved as shown at 33, 32. In operation the work W is placed on a plate 12 and the broach mounted in a push-head 10. At the bottom of the operative stroke only the stripping members 23 remain in the work. On reversal, the work is held by the stripper plate 14 while the back edges 41 complete the sizing of the hole. It is thus unnecessary to release and remove the broach after each operation.
