Abstract

446,939. Percussive drills. ERFASS, K. A. R., 6, Mosebacke torg, Stockholm. July 16, 1935, No. 20292. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 24, 1936.] [Class 124] An electric motor rotates an inclined disc 2 and hence reciprocates a piston 6. This is connected to a striking member 7 by a helical spring 5 and by air compressed in the cylinder 16. The spring is connected to the striker by its end being passed into a groove between flanges 20, 21. Oil from the chamber 13 passes through the hole 14 to lubricate the sliding surfaces between the parts 6a and 8. A spring 11 absorbs idle blows.
