Abstract: 122,863. Fairweather, W., (Singer Manu facturing Co.). Dec. 31, 1917. Multiple-needle machines; governing needle and looper threads, extra threads, attaching; thread-tensioning devices.-In multiple-needle single looper sewing-machines, the needle thread.s are controlled independently of each other and differentially. The invention is described as applied to a machine having four needles arranged in a plane transverse to the line of feed and co-acting with a single threaded looper. In the construction shown in Figs. 1. 3, and 7, the take-up devices comprise four cams c<1>, c<2>, c<3>, c<4> mounted on a shaft 145 driven through gearing from the main shaft and at the same speed. Each cam comprises two disks and acts on its thread between guides formed in the tines of a fork 151 movably supported on a post 150 and normally held in position embracing the cam by a spring 154. A stripper plate 156 with a thread passage 157 is supported between the disks of the cam, and bowed springs 170 are placed between the cams to keep the ends of thread from winding round the shaft 145 in the event of breakage. The takeup cams co-act with thread-nipping devices comprising a bushing 158 in which slides a spring- pressed headed pin 160 between the head of which and the top of the bushing the thread is adapted to be nipped. The pins are raised periodically by shoulders 164<1> on a rock-shaft 164 actuated by a crank 165 and connecting-rod 166 from an eccentric on the cam shaft 145. In the construction shown in Fig. 2, the take-up mechanism comprises a bar 31 secured to the needle-bar acting between fixed guides 30, 33, and a series of spring fingers a, b, c, d engaging the threads between the bar 31 and guide 33. The thread eyes in the guide 33 are in an inclined line, and the threads are led to them over a bar 33<x>. A plate 38 with slots of increasing depth provides stops for the spring fingers acting to limit their movements differentially. In another construction, shown in Fig. 6, the threads are acted on between two fixed guides 62, 63 by spring-controlled fingers 40 actuated by a series of cams on a shaft 47 driven through gearing from and at the speed of the main shaft. The movement of each of the fingers is determined both as regards its extent and time by the position in the group of the needle to which its particular thread belongs. In all the constructions described, the points of the needles are in a horizontal line and the eyes on a line inclined thereto so that the looper enters the loops of the needle threads at the same point relatively to the eyes. The machine also includes a thread-measuring device 192, a loop detainer 183, Fig. 14, rotary take-up and pull-off cams 202 for the looper thread, a series of thread tensions 171 and manually controlled means for releasing the tensions at the end of an operation, surface thread laying fingers, and take. up and pull-off cams c<5>. c<6> mounted on the shaft 145, acting with threadnipping means 168 for controlling the surface thread.

Abstract: 928,814. Automatic voltage control. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 7, 1961 [June 7, 1960], No. 19980/60. Class 38 (4). In a voltage regulator of the series transistor type the load current passes through a second transistor in series with the control transistor and means are provided for preventing the baseemitter voltage of the second transistor from exceeding a predetermined value whereby the short-circuit current is limited. As shown, the control transistor T1 is connected in series with a resistor R and a second transistor T3 between input terminal 1 and output terminal 3, the conduction of T1 being controlled by the circuit including potential divider R1, R2, transistor T2 and reference Zener diode Z1 so that the output volts V 0  remain constant. The base of transistor T3 is connected to the junction between a Zener diode Z2 and a resistor R4 connected in series, with a fuse F, between terminals 1 and 3 so that the maximum baseemitter voltage of T3 is limited to V z , the Zener diode voltage, and R 4  limits the diode current. On short circuit the effective resistance of T1 is zero and the short-circuit current is limited to a value given by V z /R, the value of R being so chosen that the short-circuit current is less than the maximum rating of T1 and T3 but greater than the capacity of fuse F. A resistor R5 may be connected across transistor T3 to reduce the power dissipated in T3 during normal operation. The transistors T1 and T3 may each be replaced by two transistors in parallel (Fig. 2, not shown) so as to increase the maximum current capacity of the circuit, and a shunt regulator, comprising a further transistor connected to a point between the two series transistors, may be provided so that there is furnished a current-conducting path when the input voltage is above a particular value and the output current is below a particular value.

IPC: F16H1/24
Filed: 1918-12-06
Abstract: 134,400. Franzen, F. A. Dec. 6, 1918. Toothed gearing.-In hypocycloidal toothed gearing of the type in which rollers or rings carried by one shaft engage straight slots in a part carried by the other shaft, the rollers &c. are carried in bearings in side plates and the slots are formed in a disk carried by a cup-shaped member on the other shaft. The rollers 10 are secured on spindles 17 carried in ball or plain bearings in plates 7, 8 on the shaft 2 and engage in slots 6 in a disk 5 secured to or formed on a cup-shaped member 15 on the shaft 3. The shafts are supported in a fixed casing 1 and in a plate 14 carried thereby. The disk 5 is supported by bolts 27 and sleeves 28 arranged between the slots. As the rollers engage with only one side of the slots, the slots may be tapered, as shown in Fig. 10, in order that correct gearing may take place whatever the direction of drive. In order to prevent shocks, the rollers may be braked and reversed during their period of disengagement. For this purpose, brake rollers 18 on either end of the spindles 17 are adapted to engage with either of two eccentrically arranged adjustable split rings 19, 22, according to the direction of drive. India-rubber, spring steel, or spring-pressed rigid braking-blocks may be used. The rollers 10 may be carried on spherical seatings on the spindles 17 to permit accurate engagement between the rollers and slots. Lubricant is conveyed to suitable points by pipes 33 leading from a reservoir 32 communicating with the bottom of the casing 1, the air pressure produced by the rotation of the gearing forcing up the oil.
