Title: Compensator stop-motion for use in winding, reeling, twisting, doubling, knitting orother textile machines
IPC: B65H63/036
Filed: 1928-12-22
Abstract: 329,991. Shaw, W. Dec. 22, 1928. Creel-arrangements; spindle-driving apparatus; stop-motions.-In a tension-regulating device for winding, reeling, twisting, doubling, or like textile machines, of the type wherein the yarn c, Fig. 1, is led over a guide m<1> carried by a compensator arm m pivoted at o, the compensator arm m is counter-balanced in such a manner that in combination with a spring f, Fig. 1, interposed between the arm m and means controlling the drive of the winding bobbin b, or with a spring t, Fig. 2, interposed in a connection to a brake band t' controlling the delivery bobbin, any desired tension may be imposed on the yarn and any movement of the arm be caused to decrease or increase the effect of the counter-balancing means proportionately to and in synchronism with the decrease or increase in the effect of the spring and thereby to maintain a substantially constant tension on the yarn for all working positions of the arm m. The arm m is adjustably counter-balanced by weights p<1>, r<1>, on threaded rods p, r extending from the boss n. The spindle a is driven from a gear a<1> on a shaft a<2> carrying a friction disc d adapted to be driven by a friction-wheel e. An arm g' on the starting-lever g engages a collar h and holds the disc d in contact with the wheel e against the spring f. The arm m is connected by a link k to a rod j adjustably secured in a block j<1> and from which depends a bar i shouldered at i', the end of the bar i passing through the slotted end g<2> of the lever g. A brake-strap n<3> round the disc d is connected at n<2> to a projection n<1> on the boss n. The bell-crank lever s<1>, s<2> serves to stop the machine on completion of winding. In operation an increased tension on the yarn c raises the bar i whereupon the lever g rises and the compression of the spring f is reduced, the weights p<1>, r<1> being so chosen and set that their effective moment is simultaneously reduced. If the tension continues to increase the spindle-drive is stopped. If the yarn tension is reduced the arm m rises and the discs d, e are forced more tightly into contact, the balancing moment of the weights p<1>, r<1> also increasing. If desired the two weights p<1>, r<1> may be replaced by a single weight of quadrant shape. In a further modification the weights p<1>, r<1> are replaced by springs w, y, connected to a roller u<1> movable on a curved rod u, Fig. 3, the shape of this rod to produce the desired action being determined under working conditions.

Title: A rotary machine such as an internal combustion engine, a hydrulic motor, a pump or a compressor
Inventor: EYER CHARLES
IPC: F02B53/00
Filed: 1969-07-29
Abstract: 1,272,667. Rotary-piston machines. C. EYER. July 29, 1969 [Aug. 1, 1968], No.37922/69. Heading F1F. A rotary-piston machine such as an I.C. engine, hydraulic motor, pump or compressor, comprising a generally cylindrical housing 22, Fig. 1, having inwardly directed walls 21, Fig. 1 (rt. hd. side), a central cylindrical body 26 having part cylindrical recesses and a pair of general cylindrical rotary pistons 28 having recesses 27 to form T-shaped parts 28 and whose diameters are equal to the internal radius of the housing and axes spaced apart by this radius so that as the housing and pistons rotate to form variable volume chambers any point on the circumference of a piston moves in a straight line through the centre of the housing (principle of La Hire). Thus since the extensions of the side faces of the walls 21 pass through the centre of the housing the sharp acute angled edges of the T-shaped piston parts will theoretically be at all times in frictionless sealing contact with the walls 21. In practice these sharp edges may be damaged or destroyed due to corrosion and temperature changes to destroy the sealing lines. To avoid this damage and reduce wear on the pistons the side faces 35 of the walls 21<SP>1</SP>, left hand side, Fig. 1, are spaced from and parallel to a radial plane 241 which passes through a point 31 at the centre of a circle 32 tangent to the face 35 and determines the shape of the edge 29<SP>1</SP> of the rotating piston 25<SP>1</SP> which has part cylindrical portions so that during operation different portions of the extremities of the "T's" contact the faces 35 to reduce wear. The invention is applied to an I.C. engine, Fig.2, having injection nozzles 39 through which fuel is injected into primary combustion chamber 52, 54 when at its smallest volume. In secondary combustion spaces 56a 56b, further burning may take place to increase thrust in rotating the pistons and reduce pollution before the gases are exhausted through exhausts 58.
