GEORGE L. xoLLoox AND ROBERT E. MAETIN, or SEATTLE, WASHINGTON, ASSIGNOBS To umvEEsAn HAMMER COMPANY, 0E sEATTLE, WASHINGTON, A coEronATIoN OF WASHINGTON.
AUTOMATIC HAMMER.
Patented July 30, 1918.
Application filed November 9, 1917. Serial No. 201,149,
To all whom it may concern:
Be it known that we, GEoReE L. KoLLooK, a citizen of the United States, residing at Seattle,in the county of King and State of Washington, and ROBERT P. MARTIN, a citizen of the United States, residing at Seattle,
in the county of King and State of Washington, have invented certain new and use ful Improvements in Automatic Hammers, the following being a full, clear, and exact disclosure of the one form of our invention I which we at resent deem preferable.
- operated by a spring that is periodically 1 tensioned and released by means of a motordriven cam. Our device herein claimed involves particularly an arrangement for rotating the cam which is of annular form and encircles the striker, the said arrangement being such as to provide a free space for the working movement of the head and the camrollers of the striker.
Referring to the drawings, A represents a cylindrical form of electric motor forming one section of thebody of the hammer and having at its rear end a handle B and at its other end a hollow enlargement adapted to be screwed on one end of a hollow casing which forms the remaining part of the hammer body. This casing contains the reciprocating striker D, actuated by spring E and the motor-driven cams and gears for alter-' natively tensioning and releasing the spring. The cam F,.which is .of the ratchet or sawtooth type, is annular in form and is mounted on the face of a cam gear-wheel G which is mounted to rotate on the transverse disk T with intervening friction balls. The cam and gear-wheel are concentric with the striker D and surround the upper end thereof. The striker at its lower end carries a flange-nut D against which bears one end it'is provided with an enlargedhead D On head D are mounted the cam-rollers W, here shown as three in number so as to produce three strokes of the striker for each rotation of the cam. The gear-wheel G meshes with a pinion K on a counter-shaft H which carries a pinion O that is driven by a pinion S on the motor shaft through an idler pinion R. By this arrangement the cam which surrounds the striker is rotated without interfering with the end-toend relation of the motor shaft and striker, while allowing the latter a' free space in which to operate without coming. into contact with the motor pinion S.
What we claiin'as new and desire to secure by Letters Patent is:
1. An automatic hammer comprising areciprocating striker, an actuating spring therefor, a motor having its shaft in line a distance equal to the range of reciprocation of the striker an annular ratchet cam surrounding the striker and engaged there by and a gearing connection between the cam and motor including a counter-shaft at one side of the cam and suitable pinions.
2. An automatic hammer comprising a reciprocating striker, an actuating spring therefor, an annular ratchet-cam surrounding the upper part of the striker and having its working surface on its upper side, a-cam roller mounted on the striker above the cam and engaging the said working surface, a gear wheel concentric with the cam outside of the said working surface, an operating motor having its shaft in line with the.
75 with the striker but separated therefrom by
