Abstract: 1,254,342. Free-wheel clutches. KOYO SEIKO CO. Ltd. 31 March, 1969 [29 March, 1968], No. 16755/69. Heading F2C. In a one-way roller clutch, the rollers 3 are inclined to the generating lines of inner and outer substantially frusto-conical races 1 and 2 so that relative rotation between the races in one direction urges the rollers against a stop surface 4, as shown on the inner race 1, to prevent rotation of the rollers and hence relative rotation of the races, whilst rotation in the other direction urges the rollers away from the stop surface 4 to allow them to rotate and to allow free-wheeling, the race surfaces 1a, 2a, and the rollers 3 being so shaped as to maintain line contact therebetween. As shown, the rollers are cylindrical and the surfaces la, 2a are formed as hyperboloids. The rollers may be in a punched metal cage (5), Fig. 5, (not shown). Again, Figs. 6 and 7 (not shown), the rollers are frusto-conical. Also, the surface of the rollers, may be formed as a convex hyper. boloid, Fig. 8, (not shown), the inner race surface being formed as a hyperboloid and the outer race frusto conical. Again, Fig. 9, (not shown), the rollers and outer race are concave hyperboloidal and the inner race is frusto-conical.

Title: Improvements in and relating to hydraulic stop-motions for weaving looms
IPC: D03D51/00
Filed: 1939-06-10
Abstract: 529,896. Loom stop motions. LENZ, H. June 10, 1939, No. 17068. Convention date, June 10, 1938. I[Class 142 (i)] In an hydraulic stop motion the knock-off lever 57 is pushed out of its notch 56 by a bellows cylinder 54 connected through valves 62, 63 and pipes 52, 53 to two bellows 36, 37 which are reciprocated by an eccentric 46 on one of the loom shafts 43. The bellows 36, 37 are also connected respectively by pipes 25, 26 with bellows 18, 19. The bellows 18, 19, through the crosshead 27 normally reciprocate the notched bars 32 of a warp detector. Should a warp break and the bars 32 in consequence be locked fluid under pressure from one of the bellows 36, 37 will pass through one or other of the valves 62, 63 into the bellows 54. When the knock-off lever 57 is clear of the cylinder rod 68 a spring catch 73 takes into the notch 76 and locks the cylinder in its extended state. The hook rod 77 which is connected with the rod 68 then locks the opened valve 62 or 63 in open position and keeps the closed one closed. This is to ensure that the liquid in the bellows 54 returns to the bellows whence it came. When the lever 57 is returned by hand to its notch 56 the catch 73 is freed together with bellows 54 and the valves 62, 63. Instead of locking the bellows 18, 19 by a warp detector, the passages 25, 26 can be stopped by valves 70, 98 controlled by shuttle and weft-fork detectors. When properly boxed, the shuttle 88 moves the swell 80 about its pivot 81 into the positions shown, and a connected slide 85 also into the position shown. The box and the slide 85 reciprocate in the direction shown by the arrow b and, in the position shown, the stem 87 of the valve 70 can pass through a hole in the slide 85. When the shuttle is not properly boxed, the slide 85 hits the stem 87 and closes to valve 70. The bellows 54 then operates as before. The weft feeler 90 is mounted to reciprocate in the direction of the arrow c. When no weft d is present the feeler 90 locks the slider 95 which then engages the lever 96 and closes the valve 98. The slider 95 and the stem 87 are connected to disc or other indicators 107, 106.
