Title: Improvements in shedding motions for looms for weaving
IPC: D03C1/00
Filed: 1931-07-21
Abstract: 375,101. Loom dobbies, shedding and take-up motions. GILLIS, E., 11, Parkstrasse, Beuthen, Germany. July 21, 1931, No. 20780. Convention date, July 26, 1930. [Classes 142 (i) and 142 (ii).] In shedding motions of the type in which the healds are operated by pins or rods in frames having a vertical reciprocating movement, the healds are operated by levers 9, Figs. 1 and 5, the free ends of which passing through slots in a stationary guide 46 are controlled by pattern pins or rods carried by the frame 7 which is given a reciprocating movement by mechanism operated from the lay. In the form shown in Fig. 1, the reciprocating frame 7 has studs 13 detachably secured in slots for depressing the ends of the levers 9 for operating the healds for patterning purposes, the other healds being operated by tappets &c. The frame 7 is secured by a spring bolt to its carrying means so that it may be replaced to change the pattern, or the positions of the studs 13 may be altered for the same purpose. In the form shown in Fig. 5, a pattern band 18 having holes 20 for studs 21 is used in place of the studs 13. The studs engage spring-controlled rods 23 and force them to the right where they are held by catches 25. When the frame 7 descends, the rods operate the levers 9. When the frame rises, spring-controlled tails 38 on the catches 25 engage a stop 27 whereby the rods 23 are freed from the catches 25 and move to the left. The Specification as open to inspection under Sect. 91 (3) (a) states that the frame 7 may be operated by hand or foot, and describes a form in which an oscillating arm 41, Fig. 11 (Cancelled), carrying a pattern cylinder 40 brings studs 43 on a pattern chain into engagement with the heald-operating levers 9 which are pivoted on the same axis as that of the arm 41. This subject-matter does not appear in the Specification as accepted. Take-up motions.-A rack 29, Fig. 8, slidable in the reciprocating frame 7 gears with a toothed wheel 32 connected by ratchet mechanism 33, 34 with a shaft having a universal joint and carrying a worm for driving a worm wheel on the take-up roller. When the frame 7 rises, it engages a pin 28 on the rack. When the frame moves downwardly, a pin 31 adjustably mounted in a slot 30 in the rack is engaged by the upper end of the frame and causes rotation of the take-up shaft.

Abstract: 889,552. Fluid actuation of switches. ROBERTSHAW-FULTON CONTROLS CO. June 17, 1959 [Oct. 13, 1958], No. 20839/59. Class 38 (5). A switch for adjustably controlling the water level in a washing-machine comprises a plastic shell 12 closed by a metal cover 14 which clamps the edge of a diaphragm 24 and has an opening 34 for transmission of the water head. The diaphragm 24 operates a snap-action leaf-spring toggle 38 to move contact 42 between contacts 48 and 50. A spring 72 controls the pressure at which switch actuation occurs and the tension in this spring is set by three push-buttons 106, 108 and 110 carried by a bracket attached to the shell 12 and having side members 78, 80 which carry three plates 84, 86, 88. The plate 86 is fixed and merely guides the push rods 90, 92 and 94 for rectilinear movement; the plate 84 can slide against a spring 116 and latches a depressed button while releasing the other two ; and the plate 88 forms a lever pivoted in side member 78 and guided by a slot 124 in member 80. At the centre of lever 88 is secured a stud 126 carrying a knurled nut 130 for pre-set adjustment of the lowest pressure at which the switch operates, this condition being attained by depression of button 106 which merely releases buttons 108 and 110 to permit lever 88 to rise to its highest position wherein a lug 132 engages the push rod 94. Depression of button 108 causes rod 92 to hold the lever 88 in the position shown for medium pressure operation of the switch, while depression of button 110 causes rod 94 to engage lug 132 and lever 88 then compresses spring 72 further for the highest pressure setting.

IPC: G05B11/01
Filed: 1943-12-15
Abstract: 578,048. Reversing gearing. TURCK. J. P. G. Dec. 15, 1943, No. 21069. [Class 80 (ii)] An electro-mechanical relay device utilises a friction reversing gearing to obtain rotation of a controlled shaft B in either direction from a power driven shaft F. The shaft B is supported in a floating manner by diaphragms H, I to allow endwise movement to bring a grooved pulley A into engagement on one side or the other with a friction cone'G on the shaft F which is driven from an electric motor E. The movement of shaft B is effected by the energisation of one or the other of two solenoids I<1>, I' encircling the shaft. Alternatively the movement may be effected by the difference between control currents to the two solenoids which may be the variable anode current from thermionic valves whose grids are subject to weak signal currents.

Title: Improvements in building motions for textile spinning, doubling, twisting and similar machines
Inventor: WHITTAKER HAROLD
IPC: D01H1/36
Filed: 1954-07-21
Abstract: 771,250. Package building motion. T. M. M. (RESEARCH), Ltd. July 19, 1955 [July 21, 1954], No. 21255/54. Class 120 (2). A package building motion for a textile spinning, doubling, twisting or similar machine comprises a primary operating cam, a primary lever actuated thereby, a secondary cam rotatably mounted on the primary lever, a secondary lever mounted in operative relalationship to said secondary cam so as to be oscillated by the throw thereof, and a connection between the secondary lever and a yam traversing member, the secondary lever being mounted on a pivot which is capable of being shifted in relation to the point at which the secondary cam impinges upon the secondary lever in such manner that the effective length of the secondary lever, and therefore the point of reversal of the traverse, may be varied. In the arrangement shown, 10 indicates the main heart shaped cam which rotates about an axis 11 and co-operates with a bowl 12 mounted upon the primary lever 13. Primary lever 13 also carries a secondary heart shaped cam 14 which co-operates with a bowl 15 mounted on the secondary lever 16 which is pivoted on the same stud 17 as the primary lever 13. The part 172 of the stud 17 upon which the lever 16 is pivoted is eccentric in relation to the part 171 thereof on which the lever 13 is pivoted. Motion of the secondary lever 16 is transmitted to the ring or other element by which the yarn or like is guided to the package through a chain 161 attached to the free end of the lever 16. The secondary cam 14 is intermittently partially rotated by the operation of pawl and ratchet gearing 18, 19 mounted on the lever 13 and adapted to be actuated by each oscillation thereof by the impingement of a picking lever 20 against an abutment 21. This action also serves through the shaft 29, worm gear 30 and worm wheel 31 to effect an angular adjustment of the pivot 17 and thus by shifting the eccentric pivot axis of the lever 16 to alter the effective length of the lever 16 so that successive reversals of the building motion traverse occur at slightly varying positions in each cycle during which the second cam executes a single revolution.
