Title: Machines for sewing buttons and the like on fabrics
IPC: D05B73/12
Filed: 1939-09-25
Abstract: 537,702. Sewing-machines. BRUSSELL, I. Sept. 25, 1939, No. 21526. [Class 112] A stop rod 34 has a pin 27 and oblique slot 24 connection with a slide 21 carrying a beltshifter 19. The rod is normally urged upwards by a spring and in that movement moves the belt on to a loose pulley 10. During a stitching operation, the rod is restrained by a projection 39 on a lever 38 pivoted at 41. This lever is moved to release the rod 34 by the stop-mechanism control. This control comprises a shaft 48 driven by a worm and wheel and carrying sets of stop projections 53. When one of these projections hits the tip of a lever 46 the lever is turned about its pivot 56 and its movement is communicated through an intermediary lever 42 to the lever 38. The sets of projections, 53, 54, 55, Fig. 3, which may be one, two and three projections, are axially displaced from one another and the lever 46 is moved at will to be in line with a selected set. This is done by means of a head 58, fixed on the pivot pin 56 of the lever, which has a pin engaging in a helical groove 61 on a fixed sleeve 60. By turning the head, the pivot pin 56 and lever 46 are moved axially. The machine has two needles and for a four-hole button the clamp is shifted laterally during the cycle. This is effected by a lever 72 and a cam 86 driven by gear wheels 79, 80. The clamp jaws are adjusted to suit differing sizes of button by means of a plate having divergent slots engaging pins on the jaw members. The needle thread tensions are released when the machine is stopped.

Title: Control systems having manual and automatic modes of operation
IPC: B64C27/32
Filed: 1961-06-16
Abstract: 979,494. Automatic speed control SPERRY RAND CORPORATION. June 16,1961 [July 13, 1960], No. 21792/61. Heading G3R. In a system for selectively controlling a control means manually or automatically by a manual controller or an actuator respectively, the actuator is responsive to the difference between a signal derived from operation of the control means and a reference signal which is unaffected during automatic control but varied in dependence on the difference in position between the manual controller and the actuator during manual operation. In Fig. 2, the speed of an aircraft engine 10 may be controlled manually by operating a link 51 to adjust throttle 11. Link 51 also adjusts a potentiometer 26 to produce a voltage variation which matches that derived from an engine tachometer generator 34 and applied through a frequencyresponsive network 35. The two voltages are applied in opposition to an amplifier 36 so that a fluid pressure servomotor 23 controlled by amplifier 36 remains in a fairly central position in readiness for automatic control. Automatic control is engaged by closing a switch 55 to energize an electromagnet 54 and lock shaft 22 of servomotor 23 to link 51. Since the resistance position of potentiometer 26 is fixed to shaft 22, potentiometer 26 is maintained, during automatic control, at a setting corresponding to the speed at which changeover took place without shock. Any deviation from this speed detected by tachometer generator 34 during automatic control is automatically corrected by servomotor 23 operating throttle 11. Follow up signals to the input of amplifier 36 are provided by a pick-off 40 associated with servomotor shaft 22. In a modification applied to speed control of a helicopter engine, servomotor 23 a twist type manual controller, the throttle, and potentiometer 26 are linked together by differential gearing and potentiometer 26 is locked during automatic control by operation of an electromagnetically operated brake. Specification 918,773 is referred to.
