Abstract
1493716 Rotary hand shears F J FUCHS JNR 4 Sept 1975 [11 Nov 1974] 36473/75 Heading B4B A rotary shear 1 for cutting sheet material, e.g. cloth, comprises a cutting head 11 mounted on a handle 2 in which a motor 3 is housed, a pair of first and second shear wheels 12, 13 rotatably mounted in the head, the first shear wheel being rotated by the motor via a shaft 6 and gear means 8, 25. The shear wheels 12, 13 are rotatably mounted in a frame 14 via ball bearings 22, Fig. 2, the frame being secured to the handle 2. In order to assist in feeding the material between the wheels, the wheel 12 may be provided with teeth (36), Fig. 6 (not shown), on its periphery; alternatively a spring-loaded ring (40), Figs. 8 and 9 (not shown), may be secured to the wheel 13, and arranged to urge the material against the periphery of the wheel 12. In modifications, the wheel 13 may be of smaller diameter than the wheel 12, Fig. 5 (not shown), or the wheel 13 may be mounted at right-angles to the wheel 12, Fig. 4 (not shown). The motor 3 may be mains or battery energized; the battery may be rechargeable.
