Title: Improvements in or relating to warp stop-motions for looms for weaving
IPC: D03D51/20
Filed: 1931-03-12
Abstract: 374,890. Warp stop-motions for looms. MIYATA, R., 1, Nishi - 5 - Chome, Ichinomachi, Sakai, Osaka-Fu, Japan. March 12, 1931, No. 7675. [Class 142 (i).] Detector healds are provided with end-pieces 3, Fig. 7, to accommodate a non-circular oscillatory rod 6, the locking of which serves to position a member between a camoperated hammer on the lay and the starting handle and stop the loom. The heald frames are mounted for vertical movement in fixed guides 7 at the lower end of which a cam is provided for rocking the bars from inclined to vertical position as the healds descend. In the construction shown in Figs. 4 and 7, wherein two heald wires are provided for each warp thread, two transverse bars 6, connected together by means of levers 11, 13, 15, are rocked to vertical position by the engagement of the lever 11 with a rocking member 31 which is raised by a cam 21 and is returned to dotted line position in Fig. 4 under the influence of a weight 14 on the lever 13. The return movement of the rocking member 31 normally removes a finger, which is connected to the starting handle, from the path of an oscillating hammer, but, if a bar is engaged by a detector heald as a result of warp breakage, the member 31 remains in the full line position shown in Fig. 4 and the loom is stopped. Fig. 11 shows a modified construction in which the bars 6 are moved to vertical position as the frame descends by means of a cam 43 which engages and rocks a bell-crank lever 40 against the action of a spring 41. If a bar is locked by a fallen heald wire, the bell-crank lever 40 is held in position to engage, on the upward stroke of the heald frame 1, with a collar 45 on a rod 33, the upward movement of the latter operating the stopping mechanism. In a further modification, a cam 43, Fig. 14, engages a cam member 64 provided on one of two transverse bars 6a, 6b, interconnected by pinions, the resultant rocking movement turning the bars to vertical position and rocking a spring-controlled pawl member 63 to horizontal position. If, as a result of thread breakage, one of the bars is engaged by a detector wire, the horizontally disposed pawl 63 engages a collar 45, on the upward stroke of the heald frame, and operates the rod 33 to stop the loom.

Abstract: 170,603. Anderson, J. April 19, 1920. Gas, supplying by meter; coin action, mechanical-connection; price-changing mechanism.-A price-changing mechanism particularly for gas-meters comprises a disc a connected to a plain disc j by rods m, p, q and provided with a curved slot b, a series of perforations c numbered according to the price of gas, and a centrallypivoted price-changing arm e. The arm e carries a stop f projecting through the slot b and screwed into a knob z, and a pin g to engage in one of the holes c. A coin in a coin-pocket h loosely mounted on a shaft o between the discs a, j and turned by a handle r engages, during its travel, the stop f to rotate the discs until the coin meets a discharge stop so that a spring-controlled pawl l on the rod m advances a ratchet quantity wheel k, which is held against backward rotation by a second pawl w. When the coin is inserted, it rests on a right-angled bend x on an arm i depending from the rod m and controlled by the same spring n that controls the pawl l. The initial movement of the pocket carries the coin off the step x, which then prevents the coin from being brought back beneath the coin slit. The discs a, j, are returned to initial position after discharge of the coin by the pocket h engaging the rod m.

Title: Improved variable speed gear control arrangement
IPC: G11B15/18
Filed: 1961-03-07
Abstract: 928,495. Variable-speed gear. AMPEX CORPORATION. March 7, 1961 [March 28, 1960], No. 8360/61. Class 80 (2). A variable-speed gear for use with magnetic tape recording and reproducing apparatus comprises driving and driven shafts each carrying a pair of pulleys of different diameters and two belts at all times connecting the pulleys, a belt tensioning arrangement being adjustable to so control the belts that slipping of both of them may be obtained so as to give a continuously variable ratio drive between the two shafts. As shown, an electric motor 10 has a shaft 18 fast upon which are two pulleys 20, 22 connected by flat belts 14, 15 to two pulleys 25, 26 fast upon a shaft 24 driving a magnetic head assembly 12. The two shafts 18, 24 are journalled upon a plate 17 pivotally supporting a yoke 16 carrying two jockey rollers 36, 37 engaged on opposite sides by the belts 14, 15, respectively. Thus as the yoke 16 turns about its pivot 32, one belt 14 is tensioned while the other is slackened, and vice versa, to increase and decrease the frictional grip between the belts and their associated pulley pairs 20, 25; 22, 26. A continuous variation in ratio between the shafts 18, 24 is thereby obtained between the limits imposed by the belt 14 gripping its pulley pair while the belt 15 is relatively slack, and the belt 15 gripping its pulley pair while the belt 14 is relatively slack. The control yoke 16 is biased to turn anti-clockwise of Fig. 2 by a tension spring 38, and is turned in opposition to the spring bias by energization of an electromagnet 41 having an armature 43 connected by a stiff wire 44 to the yoke. Additional tensioning of the belts is obtained from a pair of jockey rollers 47, 48 carried at the end of a lever 46 biased by a spring 49 to engage the rollers in the cross-over point of the belts 14, 15. In the form shown, the pulley pairs 20, 22 ; 25, 26 are of crowned cross-section, so that the belts 14, 15 always ride up to the parts of maximum diameter, but alternatively flanged pulleys may be employed. The two driving pulleys 20, 22 are of different diameters, but alternatively, Fig. 3 (not shown), a single pulley of uniform diameter may be employed. As a further modification, the tension adjusting rollers 36, 37 may be mounted in a modified yoke 16 so constructed that one roller can be fixed in position and the other roller only moved upon energization of the electromagnet 41, to increase and decrease the tension of the associated belts for variation in gear ratio, Figs. 4, 5 (not shown). Control of the electromagnet 41 may be effected by an amplifying system, Fig. 6 (not shown), consisting of a rotating mirror passing pulses of light to a photo-electric cell connected to an amplifier feeding to a comparator also fed with a constant signal from an independent generator, the comparator feeding through a further amplifier to the electromagnet. U.S.A. Specification 2,866,012 is referred to.
