Abstract

467,673. Percussive drills. SIEMENSSCHUCKERTWERKE AKT.-GES. Dec. 27, 1935, No. 35818. Convention date, Dec. 27, 1934. Drawings to Specification. [Class 124] A power-driven percussive-tool has springs arranged between the hammer and a member of the driving-mechanism driven with simple harmonic motion, e.g. a connecting rod, crank arrangement driven by an electric motor. The mechanism is driven at a predetermined frequency and the spring system is arranged so that this frequency is from 10-25 per cent below or more than 15 per cent above resonance. At the same time the distance of the tool-head from the point of mid-stroke of the hammer is made greater when the tool is run below synchronism, and is made less when the tool is running above its synchronous speed.
