Title: Buttonhole sewing machine
IPC: D05B73/12
Filed: 1924-02-27
Abstract: 226,134. Fairweather, W., (Singer Manufacturing Co.). Feb. 27, 1924. Buttonhole sewing-machines; starting and stopping gear.-A readily accessible controlling- wheel mounted on the rapid-feed shaft is provided with cam means thereon for controlling the period of action of the stitch-forming devices and opening and unspreading the work-clamp. The stitch-forming mechanism is of known type. The needle-bar and the turret are turned by usual connections with a feed-wheel 17. The workplate and holder are of usual construction, the longitudinal movement of the work-clamp being derived from the feed-wheel 17 and the lateral movement from a wheel 38 on the rapid-feed shaft 39 geared to the wheel 17. The shaft 39 and wheel 17 are driven at slow speed during sewing by the vertical shaft 11 which drives the needle-bar shaft and during rapid feed the shaft 39 is automatically geared to a fast-running shaft 42. The connection and disconnection of the shafts 39, 42 are effected by continuously-reciprocating levers which are held in inoperative position by latches, the throw-out latch being operated by cams on the wheel 38 and the throw-in latch by a cam on the cutter-shaft 56 and by the stopmotion mechanism which controls the connection of the sewing-shaft 13 with the continuouslyrunning pulley 59. The cutting-mechanism is operated in known manner by means including a device for coupling the shaft 56 to a continuouslyrunning pulley which also operates the clampmechanism. The period of stitch-forming is controlled by the wheel 38 through a rocking-lever 71 having a projection engaging a cam on the wheel 38 and connected by a link 70 to the stopmotion lever 58. In operation, after the buttonhole has been cut, a cam 100, Fig. 1, on the buttonhole cutter-shaft engages a T-shaped lever 101 and moves it to operate the clamp-spreading device. Just before the machine comes to rest a tooth 102. Fig. 2, on the control wheel 33 engages the end of a lever 104 connected by a linkage, 106, 107 to a push-rod 108 carrying an arm 109. The push-rod engages an arm 30 of the work-damp to open it at the same time. The arm 109 engages the clamp-spreading toggle to unspread it. Specifications 15049/15 and 126,119 are referred to.

Title: Improvements in machines for printing and registering cash items
IPC: G06C7/10
Filed: 1930-07-28
Abstract: 366,057. Cash registers. WIDMAIER, H., 9, Sackingenstrasse, Harlaching, Munich, Germany. July 28, 1930, No. 22734. [Class 106 (i).] The item, differentially set up, is printed and entered in the totalizer by a sliding movement of the structure carrying the setting, typing and adding devices. As shown in Figs. 1 and 5, a framework containing the amount-setting mechanism 12, the item type-wheels 9, the date wheels 10, and the totalizer 31, is mounted on rails 2 and by pushing the framework to the rear and withdrawing it again the item is printed on a slip inserted at 7 and on a record strip 66 and is totalized, the necessary movements of the adding mechanism being derived from a pinion 5 driving its shaft through a oneway ratchet connection and running on a rack 3 formed on one rail 2, the other rail having a rack serving with a pawl 6 to ensure full strokes of the framework. Item-setting. The setting knob 12 is fixed to a shaft 13 slidable through the item wheels 15, Fig. 3, geared at 46, Fig. 5, with spur-wheels 30 each carrying a pin 29. The wheels are set in succession by first axially adjusting the shaft 13 (as shown by a pointer 19) to bring grooves 14 into co-operative relation with a spring- urged disc 18 mounted for radial sliding in each wheel, the shaft then being turned to the necessary degree to set up the value. The wheels are supported by the framework 20 and not by the shaft 13, each wheel being provided for this purpose with a ring 16 fitting over a smaller ring 17 on the face of an adjacent wheel. Adding operation. As the framework is moved to the rear the pinion 5 drives a hollow shaft 23, Fig. 6, containing a further shaft 25 provided with fingers 24 projecting through a slot in shaft 23 into juxtaposition to the pins 29. As the shafts rotate the inner shaft 25 is displaced axially by a fixed cam 26 so as to bring the fingers 24 into the planes of the pins whereupon the fingers drive the wheels 30 and consequently the setting-wheels 15 back to their home positions. At the same time intermediate gears 39 having previously been thrown into mesh by the axial sliding of their shaft 38 due to a cam 34, cause the return movement of the wheels 30 to be transmitted to the totalizer 31 through gear wheels 40. Transfer mechanism. At transfer a single toothed disc 47, Fig. 10, displaces a compound wheel 48, 49 so that the passing of a pin 33 carried by the driving shaft can rotate the wheel still farther and effect transfer to the next numeral wheel through a spur-wheel 51. Record-strip. From a supply spool 67, Fig. 16, the strip passes around a guide roll 68, over a platen 69 and between feed rollers 63, 62 to a receiving spool 65 resting upon the feed roller 62. Feed motion is imparted by a pawl lever 53 rocked by a push-rod 58 when the framework is slid. The type-wheels are inked by a roller raised by the reciprocation of the framework.

Title: Improvements in spinning polyvinyl chloride
IPC: D01F6/08
Filed: 1950-09-19
Abstract: Solutions of polyvinyl chloride in water-soluble cyclic ethers are spun into water or an aqueous solution as a coagulating bath, and the coagulating liquid is led in the same direction as the structures leaving the spinneret at such a speed that it imparts a substantial stretch to the structures.  The structures (e.g. filaments or bristles) may be after-stretched.  The solvent may be tetrahydrofurane containing not more than 5 per cent and preferably less than 1 per cent of water.  The spinning solution may contain 25 per cent of polyvinyl chloride and preferably less if the polyvinyl chloride is very highly polymerized.  The temperatures of the spinning solution and coagulating bath may range from slightly above 0 DEG  C. to about 25 DEG  C.  In an example a 15 per cent solution of polyvinyl chloride in tetrahydrofurane is extruded downwardly into a spinning funnel of the type used for the stretch-spinning of viscose, a stream of water being led downwardly through the funnel in the same direction as the filaments.  The latter are then stretched in a channel through which water at 65-70 DEG  C. flows in countercurrent and are collected on a winding device.  The water from the spinning funnel and after-stretching channel is continuously circulated and a part of the circulated water is continuously withdrawn and replaced by fresh water.  From the liquid withdrawn the dissolved tetrahydrofurane is recovered by distillation.  The tetrahydrofurane which is vaporized during the spinning and stretching operations is recovered by means of solid adsorbents. Specification 418,550 is referred to.
