Patent GB-331067-A (GB)
Title: Improvements in looms provided with automatic weftreplenishing mechanism
IPC: D03D45/34
Filed: 1929-05-31
Abstract: 331,067. Urquhart Lindsay & Robertson Orchar, Ltd., and Anderson, J. K. May 31, 1929. Shuttle-changing mechanism.-Relates to looms having automatic shuttle-changing mechanism operated from a normally stationary shaft 5, which is rotated, to effect shuttle changing by means of a clutch disc 12 feathered on the shaft 5 and driven from a spur wheel 6 continuously rotated at a slow speed by reduction gearing from the main friction pulley of the loom, the normally-operative weaving portions of the loom being meanwhile stopped. A safety lever 23 pivoted at 25 has a toe 27 underlying and thus governing the lever 17, 16 used for moving the clutch disc 12 into engagement with the continuously-rotating wheel 6. The lay sword has a projection 30 with cam faces which overlie a toe 28 on the lever 23, except when the lay is in correct position for shuttle changing, namely with the crank shaft at back centre. When shuttle changing is to occur, the loom is stopped and a rod 22 actuated by the weft fork or weft feeler mechanism drops and normally allows the gravity-loaded lever 17, 16 to rock to start the shuttle-changing mechanism, the lever 17, 16, also rocking the safety lever 23 against the action of a light spring. If, however, the loom has stopped with the lay in incorrect position, the projection 30 stops the rocking movement of the safety lever and consequently of the lever 17, 16, so that the shuttle-changing mechanism is not actuated. If, after the lever 17, 16 has been rocked to cause engagement of the disc 12 and gear 6, the lay moves to an incorrect position, a cam face on the projection 30 actuates the lever 23, which rocks the lever 17, 16 to disengage the disc 12 from the gear 6 and stop the rotation of the shuttle-change shaft 5.

Title: An improved method of and mechanism for extracting interconnecting threads between stitched books
IPC: B42B2/02
Filed: 1931-06-09
Abstract: 372,974. Book-stitching machines. POLLAK, J. E., 20, Holborn, London. June 9, 1931, No. 16828. Addition to 362,820. [Class 112.] The method of thread extraction between successively stitched books described and claimed in the parent Specification is carried into effect by means which cause the lateral displacement of the foremost stitched book in relation to the remainder of the book pad. The forwardly moving book-pad 10 advances in the direction of the arrow A and the outermost corner of the edge E of the foremost book engages the bracket 16. The interconnecting threads between the foremost books are severed :in known manner, the severed threads hanging in loops of the adjacent stitches. By the forward movement of the bracket 16, the shaft 14 is rotated against the spring 21 and the nose of the lug 19 lifted clear of the recess 18 of the abutment 17. The shaft 14 is thus free to be displaced axially under the influence of the spring 23, moving the arm 15 so that the bracket 16 and foremost book held thereby are displaced laterally relative to the remainder of the book pad which is held in position by the stop 11a. By this means, the severed threads are withdrawn from the loops which in they hang. The shaft 14 is restored to original position by the cam 30, follower 29 and lever 28.

Abstract: 429,656. Insulation for dynamo - electric machines. SIGMUND, M., Lutin, near Olomouc, Czecho Slovakia. June 6, 1934, Nos. 16834 and 16835. Convention dates, June 7,1933 and May 12,1934. [Class 35] A liquid-tight envelope for the stator winding is produced by forming on the stator by means of dies, end chambers with divided walls and by uniting them with insulating-tubes previously placed in the slots with mandrels. After vulcanization the slot ends are exposed by folding back the chamber walls to permit the winding to be accomplished and finally the chamber walls are returned to their correct shape and united. In the form shown, rubber rings 103-106 and the die 17 are arranged at the end of the core when the rubber tubes 1 and mandrels 15 have been inserted in the slots, and the mould is completed by the mandrel 16 and the counter-die 22. Pressure and heat are applied to unite the rings and the tubes except where the die ring 18 keeps the walls apart, and the upper wall so separated is bent back to facilitate the winding operation after which the end chambers are sealed. The sealing may be by vulcanization, adhesion, or the parts 103, 106 may be forced together by a clamp. The slots may be lined with linen or pressboard.
