Abstract: 554,220. Fluid-actuated valves ; actuating mechanism. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Oct. 26, 1942, No. 15020. Convention date, Oct. 24, 1941. [Class 135] [Also in Group XXXVII The blast-valve of a gas-blast switch is provided with means controlled by the contactactuating mechanism for opening the valve during opening, but not during closing of the switch and with further means for opening the valve, if the switch, during closure, is reopened when the normal valve-opening means is inoperative. The valve 45 controlling the blast from reservoir 1 to the arc space between fixed and movable contacts 13, 17, respectively, is operated by a lever 49 pivoted at 51 and provided witth spaced arms 53 adapted to be operated by a crank 29 on a shaft 31 forming part of the contact-actuating means. The arms are interconnected by a pin 59 on which is pivoted a spring link 61, 65 normally holding the valve closed. A pin 67 screwed into each arm 53 serves as pivot for the limbs of a U-shaped yoke member 83, the bight of which has a hole 85 in which the stem 89 of a U- shaped yoke 67 is adjustably fixed, by means of interengaging nuts 91, 93. The yoke 87 carries a roller 107 which is normally urged against an adjustable stop 109 on the end of an arm 53 by means of a spring link 97, 99, which is pivoted on a pin 95 between the limbs of member 83 and engages an eyelet 103 pivoted to a bracket 101 on an arm 53. During a normal opening movement, the leading cam surface 100 of crank 29 engages roller 107 and lifts arms 53 to open the valve 45 ; the roller finishing at the lower cam surface 113. During the subsequent closing movement, surface 113 rotates member 83 and yoke 87 counterclockwise about pins 67 into an inoperative postion. If the switch closes on to an overload, however, and the crank movement is reversed, further means are provided to open the blast valve. A further pair of plates 71 are pivoted on pins 67 intermediate the arms 53 and member 83 and are urged clockwise by a spring link 75, 77 pivoted on pin 59 and taking in an aperture in a pin 73 interconnecting plates 71. During closure, a pin 111 on crank 29 engages and deflects the plates 71, but clears them at surface 115. On reversal of crank 29, pin 111 engages surface 115 to rotate the plates 71 clockwise and by means of surface 79 thereon engaging pin 59, rotate the arms 53 clockwise to provide an immediate blast. The plates 71 are apertured at 81 to allow movement of pin 105. In a modification, Fig. 5 (not shown), the pin 111 in the closing movement engages ratchetwise a series of notches in plate 71 so as to provide more than one valve opening position if the switch reopens. By means of stop 109 and nuts 91, 93 adjustment of any one pole in relation to the others can be effected for simultaneous application or otherwise of the blast of a multipole switch.

Title: Improvements in and relating to roll winding machines for flax, hemp, jute and the like
IPC: B65H54/28
Filed: 1941-12-12
Abstract: 552,207. Winding yarns. MACKIE & SONS, Ltd., J., and MACKIE, J. P. Dec. 12, 1941, No. 16082. [Class 120 (ii)] The traverse bar of a machine for winding flax &c. into cross-wound roll form, is actuated by cam mechanism which is adapted to effect the reversals of the traverse bar comparatively gradually while towards the ends of the traverse tye yarn is displaced by additional means which maintain the same traversing speed and give substantially sharp reversals of the traverse of the yarn at each end of the roll. As shown the traverse bar 23 is actuated by a cam 24 with the parts 27 of the cam groove formed to a smooth curve of large radius to give a gradual reversal of the bar without shock, the yarn from the guide eye 22 of the bar passing over the surface of a roller 29 to the roll 30 which is driven by the roller. The roller 29 has V-shaped grooves 37 near its ends and just when the bar 23 beings to slow down, the grooves pick up the yarn and complete its traverse to the ends of the roll at the same traversing speed as that given by the parts 26 of the cam groove and back again until the bar 23 has got to its maximum speed again and resumes control of the yam traverse. The roller 29 may be driven from the shaft 25 of the cam 24 and the grooves 37 may be provided in a roller separate from the roller 29 but geared thereto ; the grooves in the roller 29 may be replaced by shoulders thereon. In another form the traverse of the yarn at the ends of the roll is effected by notched levers oscillated by cams on a shaft geared to the shaft of the roller driving the roll.
