Abstract

411,913. Jigging - mechanisms for screens etc.; bearings. BRAMWELL, I. L., Wentworth House, Station Road, Birtley, and BIRTLEY CO., Ltd., Birtley, Co. Durham. Dec. 16, 1932, No. 35723. [Class 117.] Reciprocating masses such as screens, coalcleaning tables, &c., which are buffered by torsion springs as described in Specification 360,403 are supported on rollers f running on surfaces l, e fixed to the reciprocating mass and the base frame respectively. Preferably the surfaces are inclined and the lower surface is mounted in an arcuate groove c and adjustably secured by a screw bolt g. To prevent the mass from leaving the supporting rollers, it is held down by a spring pivotally secured thereto and to the base.
