Title: Improvements in zigzag-stitch sewing machines
IPC: D05B3/02
Filed: 1934-12-20
Abstract: 436,049. Sewing-machines. FAIRWEATHER, W. C., 65, Chancery Lane, London.-(Singer Manufacturing Co.; Elizabeth, New Jersey, U.S.A.) Dec. 20, 1934, No. 36512. [Class 112] In a zig-zag stitch sewing-machine, the needle gate is vibrated by a pitman which is laterally oscillated by a cam, a roller on the pitman engaging a guideway which can be angularly adjusted and bodily displaced in order to vary the amplitude of vibration and the neutral position of the needle, respectively. The needle gate 13 through which the needle bar slides, is pivoted at its upper end 14 and has a lateral projection 18 carrying a slide block 19 engaged by the forked end 20 of a lever 22 connected to a pitman 24. The pitman 24 has a forked end 25 engaging a cam 26 on a shaft 27 geared by skew-gearing from the main shaft 5 and at half the speed. A roller 30 on the pitman engages a slot 31 cut in a head 32 secured on the end of a shaft 36 which extends to the opposite side of the machine head where it is fitted with a thumb lever 47 secured by a set-screw 46, Fig. 5. The shaft 36 passes through a sleeve 37 on which is eccentrically mounted a sleeve 42. The sleeve 37 passes through slots 41 in a guide member 38 and the eccentric sleeve 42 engages surfaces 44<1> on the member 38. The slots 41 are parallel to that position of the guide 31 which ensures the maximum longitudinal travel of the pitman 24. The sleeve 37 has a handle 45 by turning which the sleeve can be moved from one end of the slots 41 to the other thereby moving the guide 31 from a position in which the roller 30 makes equal excursions on opposite side of the centre of the shaft 36 to a position in which the roller reaches the centre of the shaft only at one end of its travel. By extending the slots 41 an equal adjustment in the opposite direction may be made. A member 52 secured to the guide 38 by screws carries two scales 70, 71 co-operating with two pointers 75, 76 on a member 74 secured to the thumb lever 47 by a screw 73. Movement of the handle 45 causes one or other of the pointers to be covered up by its scale in its two extreme positions of adjustment. Adjustable stops 57, 58 on a plate 48, which has a lug 50 engaging slots 53, 54 in the member 52 and guide 38, limit the movement of the lever 47. The guide 31 has a curvature which is centred at the end of the pitman when the lever 47 is in its lower position, the pitman then vibrating idly without moving the needle gate. A notched spring wire 62 secured to the plate 48 by a screw 61 yieldingly engages a pin on the lever 47, and a spring washer 66 between the head 32 and the guide member 38 assists in keeping the shaft 36 in any angularly adjusted position. Specification 416,619 is referred to.

Abstract: 803,709. Veolicity-modulated tubes. GENERAL ELECTRIC CO. Dec. 30, 1955 [Jan. 25, 1955], No. 37450/55. Class 39(1). In a velocity-modulation device of the klyston type having a triode input section including a cathode control electrode and second electrode spaced apart in that order in the direction of the electron beam, capacitive coupling is provided between the control electrode and cathode so that they operate at substantially the same r.f. potential but are maintained d.c. insulated from each other and the control electrode is so spaced relative to the cathode that the leakage from any electromagnetic field established between the control electrode and second electrode causes space charge control of the cathode emission to augment the velocity modulation of the electron beam. As shown in Fig. 2, the tube comprises an input section 20 a drift tube 21 and an output section 22. The beam is generated by a cathode 33 comprising an emitting surface 34 and a heater 35 and passes through a control grid 37 spaced from the emitter 34 by an insulating annular disc 40 of zero impedance to radio frequency, the control grid 37 being in D.C. contact with the inner member 25 of the input resonator. The input resonator comprising mixer and outer members 25, 24 is tuned by plungers 27 and fed by a capacity coupled coaxial line 32. The output resonator, 51, 52 is similarly tuned by plungers 53 and feeds a coaxial line 62. The drift tube 21 is formed by a conductive non-ferromagnetic cylinder 41 attached at either end to the outer members 24, 51 of the resonators, the beam passing via gaps 48, 58 into and from the drift tube through grids 44, 45 respectively. In order to alter the Q factor without altering electrode spacing or potential levels lossy material 70, Fig. 4, may be provided at the grid end of the inner member 25 of the input resonator. The lossy material may be quartz coated with stannous chloride or may be a ferite and may be adjustable axially. In a modification the inner member 25 of the input resonator contacts the cathode 33 instead of the control grid 37. For optimum efficiency the A.C. velocity component of the stream should lag the A.C. current component by 90 degrees and the average transit angle from cathode to drift space entrance should be 2# radiam.
