Filed: 1927-07-16
Abstract: 295,494. Scott, H. July 16, 1927. Driving-gear for mangles and wringers comprises a combination of toothed and chain and sprocket gears. A bracket K is keyed to the lower roller shaft A and carries at its free end a bearing for a stud M to the opposite ends of which are secured a sprocket wheel P and a pinion N respectively. The sprocket wheel is driven by a chain R from a sprocket wheel S integral with the hand-wheel E, which is loose on the shaft, whilst the pinion meshes with and runs round a larger gear wheel F which is free on the shaft but is held stationary by being formed integrally with a bearing T of the shaft, the bearing being bolted to the frame of the machine. Alternatively the gear wheel may be held stationary by bolts passing through the web H of the gear wheel and'through sleeves J and the machine frame.
