Abstract

118,802. Speiser, C. March 7, 1918. Shedding-motions; shedding-tappets; tappet-shafts; driving - arrangements. - In a ribbon or other loom in which the warps and the direction of movement of the lay are obliquely upright, the healds are in a correspondingly inclined position and have the form of rigid harness frames sliding in a guideframe. The heald frames 6, Fig. 6, are received in grooves in rigid harness frames 3 and are retained in position therein by spring catches 7. The frames 3 are mounted to slide rectilinearly in guides 4 on a frame 5, and are connected by rods 9, Fig. 1, to tappet-levers 8, which are pivoted on an inclined shaft 11 and are operated by tappets 13 on a shaft 14 and by springs 12, adjustable stops 43 limiting the spring-actuated movement of the levers. The inclination of the shaft 11 is so arranged that the healds form a clean shed. The tappet-shaft 14, Fig. 2, is divided transversely into two parts, to which are secured by collars 15, 17 and bolts 16, 18 the tappets for the ground and border weaves respectively. The two parts of the shaft are driven separately from a common shaft 27 through gearing including change-speed gears 19, 20, bevel-gearing 21, 22, intermediate shafts 23, 24, and bevel-gearing 25, 26, the shaft 27 being driven through gearing 28 from the driving- pulley 29. The shedding may otherwise be effected by a dobby.
