Abstract

897,042. Wrenches. SHELLEY Ltd., R. T. March 14, 1961 [May 10, 1960], No. 16435/60. Class 61. A ratchet spanner has a rotable member 13 provided with a central through opening 15 for engagement with a nut or the like, the member 13 being rotatably mounted in a lever handle 10 carrying a spring pressed pawl 17 located in a slot 12 for engagement with peripheral ratchet teeth 14 on the member 13. The member 13 is formed from flat steel sheet or plate and is a rotatable working fit in the circular opening 11 in a handle formed from flat steel plate or sheet of substantially the same thickness as that from which the rotatable member is formed, the member 13 being retained in the opening by apertured cover plates 19 secured to opposite sides of the handle. The ratchet teeth 14 have short, part circumferential lands 16 between them to provide a substantial bearing area between the member 13 and the inner edge of the opening 11.
