Abstract: 115,506. Sedgwick, F. May 15, 1917. Machines for coding and decoding; typewheel actions. - In machines in which the code - mechanism is adapted to move the type-wheel to the right or left of the position determined by the keys, the controlling-member for the code-mechanism is provided with means of the character described below for readily changing the code-key. In the machine shown, the devices for moving the type-wheel to the right or left are operated by pins 26, 27, which are inoperative and operative in the raised and depressed positions respectively. According to the invention, the controlling-member consists of an intermittingly-moving disk 9 provided with two series of holes 21, 22 arranged to pass over the pins 26, 27 respectively, each hole being adapted to be closed by a removable plug 25. The holes are formed with recesses 24<a> arranged to receive flanges 24 on the plugs. The disk 9 and a cap 11 for securing the plugs are mounted loosely on a stud 10, the cap being prevented from rising by a catch 14 on a knob 12. The disk and the cap are secured to an annular Geneva-pinion 5, driven by a pinion 4, by means of a pin 17 passing through apertures. To permit of adjustment of the disk and cap with reference to the pinion 5, a number of apertures are provided in the pinion.

Abstract: 453,434. Stapling continuous filaments. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and TAYLOR, W. I., c/o British Celanese, Ltd., Spondon, near Derby. March 6, 1935, No. 7074. [Class 120 (iii)] A continuous product containing staple fibres is produced by passing a bundle of continuous filaments 14 between a pair of rollers 1, 2, Fig. 1, in pressure contact one at least of the rollers having a cutting surface whereby the filaments are cut into staple fibres and one roller being positively driven while the other is driven thereby its rotation being resisted by fluid action so as to cause it to rotate at a peripheral speed different from that of the positively driven roller. The bundle of filaments 14 is drawn through the rollers 1, 2 by the rollers 3, 4 the roller 3 being grooved and driven at a higher speed than the roller 1. The latter is formed with sharp-edged flutes which convert the continuous filaments into staple fibres. The bundle of staple fibres may then be twisted and wound on to a package 18 by a cap spinning device 17. The roller 2 rests on and is driven frictionally by the roller 1 and is provided with a vane wheel 21 mounted on the roller spindle 22 outside the bearing 9. Air from a tube 23 impinges on the vanes 27 and causes the roller 2 to rotate more slowly than the roller 1. The air jet may be such as to stop the roller 2 or to rotate it in the reverse direction. In a modification the roller 2 is mounted in a lever 30 pivoted loosely on a shaft 31 which carries four vanes 36, Fig. 2. The spindle 22 of the roller 2 is connected by gear wheels 32 .. 35 with the shaft 31 and the rotation of the roller 2 is checked by air resistance to the rotation of the vanes 36. Specifications 424,683 and 424,830 are referred to.
