Abstract
375,231. Hand cranks. GRAMOPHONE CO., Ltd., Hayes, Middlesex. Jan. 30, 1932, No. 2872. Convention date, March 24, 1931. [Class 136 (ii).] The detachable crank, Fig. 6b, of a talking machine is slidable within or upon the winding shaft, Fig. 6a, either member having one or more feathers 15 engaging a number of grooves 19 in the other member. The feathers and grooves may be rounded, as shown, or square and the number of grooves may be a multiple of the number of feathers. Six grooves are shown for three feathers, and three or four for one, so that the crank is engaged after only a partial turn. The crank may be caused to wedge on the shaft by tapering the inner ends of the grooves or by widening the corresponding parts of the feathers. The Specification as open to inspection under Sect. 91 (3) (a) states that the grooved member may have only one groove. This subjectmatter does not appear in the Specification as accepted.
