Title: Improved variable speed gear
IPC: F16D33/00
Filed: 1933-07-27
Abstract: 423,187. Hydro-mechanical variablespeed gearing. STOCK, R. T., 23, Mount Road, Hendon, London. July 27, 1933, No. 21148. [Class 80 (ii)] In variable-speed gearing of the kind comprising a transmission epicyclic gear train having a reaction member controlled by an hydraulic coupling, the two elements of the coupling are geared together in a ratio which is fixed or fixable at nearly unity. Planet gears 8, Fig. 1, on a spider 7 fast on a driving-shaft 3 mesh with a sun gear 9 fast on a driven shaft 5 and with an internal gear 10 which is the reaction member. The gear 10 is rigid with the primary element 11 of the hydraulic coupling which is geared to the secondary element 17 in a ratio approximating unity. The hydraulic elements 11, 17 are rigid with internal gears 12, 16, respectively, which mesh with stepped planet gears 13 supported on a loose ring 14, the gears 13 being constrained by being in mesh with a sun gear 13b fixed to the gear casing 1. In a convenient form, the element 17 rotates three per cent slower than the element 11. Vortex motion is set up between the coupling elements, and the torque transmitted may be varied by obstructing vanes 20 arranged round the coupling and movable into the space between the elements 11, 17 either by hand or by a governor. Regulation may alternatively be effected by adjustable sluices or by varying the amount of liquid in the coupling or the distance between the coupling elements. Specifications 1163 /77, [Class 80], and 13864 /06, [Class 69], are referred to in connection with the type of coupling which may be used. In Fig. 3 is shown an arrangement with two transmitting trains for driving forwardly and reversely respectively, and in which speed variation is effected by allowing the constraining or fulcrum sun gears 13b, 35 to slip. The forward train is the same as shown in Fig. 1 except that the sun gear 13b instead of being fixed is connected to an eccentric 25<a> adapted to be held fast or to be allowed to slip away in a controlled manner by an oil pump 37<a> controlled by a throttle valve 42. Rigid with the driving spider 7 is the annulus 26 of the reversing train, the sun gear 29 of which is fast on the driven shaft 5. The reaction member of this second transmission train is the planet-carrier 28<a> which is rigid with a primary hydraulic element 28. The secondary element 30 of this reversing unit is geared to the element 28 by stepped planets 32 on a loose carrier 34 and meshing with a sun gear 35 which is connected to an eccentric 36<a> which can be held fast or allowed to slip away by a second oil pump 38 controlled by a throttle valve 45. Variable forward speeds are effected by closing the valve 42 with the valve 45 open. Variable speeds in the opposite direction are effected by closing the valve 45 with the valve 42 open.

[Class 80 (ii)] [Also in Group XXVII] In a plant comprising two internal-combustion engines which have the ends of aligned crank shafts 1, 1a, connected together by a coupling member 11, the drive to a shaft 10 is conveyed through a pinion 7 which is coupled by a floating-sleeve 20 having end flanges 19, 21 splined respectively to the member 11 and the pinion 7, the splines permitting slight relative radial movement as the crankshafts bend under load. The arrangement is particularly applicable to an H-type engine having a second pair of aligned crank shafts coupled to a pinion 8, both pinions 7, 8 being carried in rigid bearings 22. The sleeve 20 is retained by abutment members 17, 23.

Abstract: 629,392. Electromagnetic switches. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Aug. 7, 1947, No. 21561 Convention date, Sept. 15, 1942. [Class 38(v)] In an electromagnetic contactor the member c carrying the armature D and movable contacts 50 is centrally pivoted on a knife edge 19 and the armature moves between the magnet 3 and the base 1 so that when it moves away from the base into engagement with the magnet the contacts 50 move towards the base into engagement with fixed contacts 51. The knife edge 19 is an edge of a polygonal rod 18 slid into position in ears 16 of two legs 6 projecting from the base and is engaged by two wide angled parts fixed to the member C and pressed against the knife edge by a biasing spring 25. The armature D is mounted on the member C by a rivet 30 with a conical sleeve 31, Fig. 3 which would allow universal movement for selfalignment were it not that the undesirable movement about an axis 36 is prevented by the engagement of parts 37, 38. Rubber brushes 33 are provided. The movable contacts-50 are biased by a spring 55 arranged at an angle so as to take the weight of the' contacts and prevent shoulders 56 from wearing. The planes of the fixed contacts, moving contacts, armature face and fixed hole faces all pass through the axis 19 so that no wiping action takes place on engagement.

Abstract: 441,862. Impedance networks ; valve circuits. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. July 25, 1934, No. 21786. Convention date, July 25, 1933. Drawings to Specification. [Classes 40 (iii) and 40 (v)] A frequency-selective device, particularly for use in the search-tone method of analyzing complex oscillations, has a resonance curve of constant maximum height but variable breadth. Thus it may consist (Fig. 1, not shown), of an L-section whose series arm comprises a variable resistance while its shunt arm comprises a rejector circuit whose damping is neutralized by means of negative resistance, or vice versa. In a modification (Fig. 2, not shown) a T- section with a back-coupled valve is used to neutralize the damping of the tuned circuit. The resistance may vary exponentially with time for the purpose of the search-tone test ; and the damping may be varied so as to give high selectivity for low-frequency tones and vice versa.

Abstract: 1.098,801. Gripper shuttle looms. MASCHINENFABRIK - CARL ZANGS A.G. May 24, 1965 [Jan. 22, 1965], No. 21822/65. Heading D1E. Shuttlerace; beat-up motion. A stationary shuttle race for a gripper shuttle consists of thin elements 11, Fig. 2, having passages 93 for compressed air which blows the weft through gaps 9 towards the fell so that it passes over and comes in front of a beat-up comb 22 operating along a path A. A second comb B operates along a path B, such that one or other comb always penetrates the warp sheets to maintain the spacing of the threads. Weft supply; shuttle; picking. The shuttles, Fig. 3, have a cylindrical body into which the end of the weft thread is blown by a nozzle 43, Fig. 5, which momentarily lifts a spring-loaded ball 42 off its seat to enable a short length of thread' to pass it. The shuttle is propelled by a picker 76 of U-section operating astride the nozzle 43. Air flow is maintained continuously in the nozzle 43 to help the shuttle to draw weft from the supply bobbin 44'. When the shuttle reaches the opposite side of the loom, it is received in a rotary shuttle box similar to the box 56 from which it was picked. The shuttle boxes turn so that the shuttle is moved forward towards the fell, the weft at the picking side of the loom being similarly moved forward by a clamping and cutting device 70 turning with the box 56, and being then cut. The free end is drawn back to the mouth of the nozzle 43 by a take-up device 45, a clamp 51 having been closed to prevent further withdrawal of weft from the bobbin 44' when the shuttle completed its travel. As successive turns of the shuttle boxes bring empty shuttles to the bottom, they are returned to the picking side of the loom by an endless chain (not shown) having vertical fingers which push the shuttles along a slotted tube 89, Fig. 2.

Hot gases from the central heating section may also pass through openings 9 in cylinder 2 into a central duct 20 under control of damper 21, from which duct 20 condensation products may drain away through a lower section 23.  In a modification, Fig. 3 (not shown), gas inlets 73 and outlets 84 are replaced by perforated areas in cylinder 2 above and below the funnel 22 formed on lower duct 23, whereby hot treatment gas introduced through the space between said duct 23 and said cylinder 2 may pass through the charge material and out into central duct 20.
