IPC: D04H3/16
Filed: 1928-09-19
Abstract: 323,221. British Celanese, Ltd., and Taylor, W. I. Sept. 19, 1928. Apparatus for making filaments.-Travelling artificial filaments are subjected to a fluid blast, stream or jet so as to produce a tangled mass suitable for use as described in Specification 323,209, [Class 120 (iii), Yarns &c.]. Suitably, the filaments are subjected to an air blast by means of an ejector device of the kind described in Specification 322,557, and, as described in that Specification, the filaments may also be stretched by the blast. Alternatively, the filaments may be stretched before subjection to the blast. The filaments may be produced by dry- or wet-spinning, and may have a base of cellulose or cellulose acetate or other ester of cellulose or cellulose ether. As shown in Fig. 1, filaments 5 from a jet 6 are passed through an ejector device 8 of the kind described in Specification 322,557. Compressed air is supplied to the device through a pipe 9, and further blasts may be introduced into the cell through pipes 17. A baffle 16 assists the dispersion of the filaments, which collect in the bottom of the cell and are withdrawn through a door 15. In Fig. 2, the ejector device 21 is located outside the cell, and the filaments 18 are stretched before reaching the device by passage round a roller 20 rotating at a sufficiently high speed. The filaments are dissociated one from another before reaching the ejector device by passage over guide-bars 23, 25 and under a bent guide-bar 24. Specifications 165,519 and 198,023 also are referred to.

Filed: 1925-10-28
Abstract: 253,408. James, R. W., (Remington Accounting Machine Corporation). Oct. 28, 1925. Adding-apparatus ; clear signals and marks.- In a combined typewriting and computing machine having a plurality of column totalizers and a single line totalizer adapted to jump from one column to another a key for printing a special characteristic mark is provided, the key being locked against depression unless the total from the line totalizer has been correctly taken and the wheels stand so as to exhibit zero. In the Remington book-keeping machine shown in Figs. 1, 2, and 3, the column totalizers 11 are mounted on a carriage 10 movable in unison with the typewriter carriage and the line totalizer is mounted in a carriage 12 intermittently hooked up to the column totalizers by a hooked bar 14 pivoted to a bracket 15 on the carriage 12. The totalizer 13 comprises a series of numeral drums 25 each having a pinion 24 with a mutilated tooth engaged by a tooth of a comb 26 when the drums indicate zero. The comb 26 is pivoted at 27 and has an arm 28 articulated with a bell-crank 30 under the control of a spring 31. The bell-crank 30 has a projecting finger 32 which will be rocked rearward when the totalizer is clear. In this position the finger co-operates with a cam-bar 40 having an incline 41 and connected by pins 38 to a spring-controlled lever 34 pivoted on a bracket 33. The lever 34 is guided by a notched projection 37 thereon engaging an edge of the bracket 33. When the carriage 12 jumps back to its initial position the projecting finger 32 raises the lever 34 whereby a pivoted lever 42, having a forked end 44 embracing the projection 37, is rocked to displace a tongue 45 out of the path of a bellcrank 47 operatively connected to a special key 52. The tongue 45 projects through a hole 46 in the frame plate 8 and the bell crank 47 is pivoted on the opposite side of the said plate. To prevent mis-operation the arm 53 of the bell crank 47 is extended forwardly at 54 to ensure that the hole 46 is covered when the key is depressed and thus prevent the tongue 45 getting in front of the bellcrank 47. The parts are covered by a plate 55 to render them inaccessible.

Transistor headers (Fig. 1) are delivered from bowl vibrator 10 (Fig. 5) so as to be orientated by vibrator conveyer 11 (Fig. 2) and passed therefrom on to screw conveyer 12 which conveys them till they are discharged by member 78. Bowl vibrator 10, Fig. 5.-The bowl is formed with internal track 13 up which the headers pass till they reach spout 17 and fall into funnel 18. Spout 17 is so shaped as to receive a header with the short wires forward, but to reject headers otherwise orientated and to deflect them back into the bowl. Vibrator conveyer 11, Fig. 2.-The headers received in funnel 18 pass down tube 22 and fall into slot 25 formed therein so that the longer wires fall through the slot and the header is conveyed to track 34. Tube 22 and track 34 are carried by springs 31, 32 vibrated by vibrator 40. The track is formed with bends 44 which cause the header to rotate and then advance to the position where plough 50 overlaps half the track. The headers pass the plough uniformly orientated with the two wires 4 and 5 grazing the edge of the plough. An overhead arm 51 is provided which is pivoted at 52 biased at 53 and vibrated at 55. The arm 51 smacks down on top of track 34. A switch 54 is provided. If the arm thereby contacts a header beneath it the feed of the headers is stopped, but if no header is beneath the bar 51 when it comes down on top of track 34 then the feed is recommenced. The headers are fed from track 34 on to screw conveyer 12 and are carried along by the turns of the screw being supported at the other edge by rail 76, and are discharged upwards by arms 78.
