Abstract

1283846 Percussive tools REGUS AG 7 July 1970 [10 July 1969] 32858/70 Heading B4C A percussive tool comprises a vibratory mass 4, means 1 for vibrating the mass 4, a coil spring 12 for cushioning the mass 4 against a fixed bearing portion 13, the spring 12 being divided into portions 12a-12c by breaks or non- resilient portions, a buffer spring 15 and a member 14 for transmitting part of the vibratory energy to a tool bit 16. The portions 12a- 12c are preferably separate, e.g. joined by collars, and each identical to the spring 15. The tool bit 16 is held freely slidably within a holder 17 by a screw 18. The vibratory mass 4 is slidable on rods 5, the vibrating means 1 comprising balanced eccentric weights, rotatable in opposite directions about a common axis by means of an electric motor 6 acting through a friction clutch 7 and bevel gears 3, the effects of the masses superimposing in the axial direction of the tool and cancelling out transversely thereof.
