Abstract

889,239. Machinery guards; tensioning driving belts. ELLIOTT & CO. Ltd., B. Aug. 27, 1958 [May 27, 1957], No. 16727/57. Addition to 832,749. Classes 80 (1) and 80 (4)] In a drilling or other machine a belt 62 coupling driving and driven pulleys 64, 60 is surrounded by a guard 70 which may be tilted about a fixed rod 72 to give access to the pulleys for belt-adjustment, the guard 70 being coupled, e.g. by a pin-and-slot connection 82, 84, to the support of one of the pulleys so that the latter is moved to slacken the belt as the guard is tilted to the chain-line position. As shown, the pulley 64 is stepped and mounted on the shaft of an electric motor 68 which is pivotally mounted on a fixed rod 76. The pin- and-slot connection 82, 84 comprises a rod 82 carried by the guard and slots 84 in side plates on the motor. The head 90 of a spring-loaded catch lever pivoted on the rod 76 co-operates with the rod 82 to retain the guard and motor either in the tilted or the normal positions. The rod 76 carrying the motor 68 is mounted in a bracket 96 secured to the drill frame 92 by screws 98 passing through slots in the bracket, the slots allowing adjustment of the bracket 96 to vary the tension of the belt 62.
