Title: Lock stitch sewing machine
IPC: D05B57/14
Filed: 1924-05-03
Abstract: 234,261. Fairweather, W., (Singer Manufacturing Co.). May 3, 1924. Sewing - machines; lockstitching by hooks; governing needle thread.-A take-up of the kind comprising an arm operated by a crank and pivoted to an anchor link is arranged to draw up the needle-loop to the work before the needle begins its down stroke, and to give slack before the needle has descended through a distance equal to the distance between its eye and point. The take-up comprises a bent arm 23, 24 connected to a crank pivot 7 lying outside and slightly to the rear of the pivot 6 of the needle-bar actuating crank. A link 26 connects the arm 23, 24 to the frame. The needle-thread passes through a tension device 29 and under a check-spring 31 before passing through the eye 25 of the take-up. An arm 32 extends below the spring 31 to limit its movement and is adjustable in accordance with the thickness of the work. The take-up is employed in conjunction with a rotary book making three revolutions to one reciprocation of the needle. Specification 233,812 is referred to.

Title: Improvements in or relating to ball-type centrifugal governors
IPC: G05D13/08
Filed: 1966-03-14
Abstract: 1,074,108. Centrifugal governors. ROBERT BOSCH G. m. b. H. March 14, 1966 [March 12, 1965], No. 11002/66. Heading G3B. In a governor of the kind in which balls 4 are driven by a cage 3 and co-operate with a disc 13 to actuate a bell-shaped sleeve 7, the disc has a stationary inner portion 14 and a rotatable outer portion 15. When the balls are in contact with the inner portion at low speeds they rotate causing the sleeve to rotate relatively to the drive shaft 2 to reduce friction. In addition, the balls, and hence the sleeve, experience simultaneous axial impulse due to depressions 17 in the portion 14. The sleeve is connected to the rack 12 of a fuel pump by a lever 11 or by a three-dimensional cam. The portions 14, 15 may be formed as integral parts of the governor housing and the cage 3.

Abstract: 750,056. Holding and picking-up tools. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 15, 1954 [April 22. 1953], No. 11160/54. Class 61 The remotely controlled gripping means 14 of a  tongs device is detachably coupled to a supporting rod 2, and a holder 4 is combined with the tongs for preventing the means 14 from rotating whilst operating the coupling. Further, the coupling, which may be a bayonet joint, (Fig. 2, not shown), includes a device 27 which locks the parts in position and which moves into or out of position upon a combined rotary and longitudinal movement of the rod. The tongs shown includes a handle 1 having a trigger 5 which actuates a spring-controlled rod 8-10 linked to the arms 14; the parts 8, 10 of the rod are screwed together at 22 and can be separated by rotating a knob 24 on the part 8. The arms 14 are pivoted to a bridge-piece 11 having a part 21 which has the bayonet joint connection with the rod 2 and which carries the spring-urged locking member 27. This member 27 normally projects into the open-ended slot of the bayonet joint to prevent unintentional unlocking of the parts. The holder 4, which may be fitted in a chamber for handling radioactive articles, has slots in its walls 29, 30, for receiving the tongs device. To uncouple the parts, the knob 24 is first rotated to separate the rod parts 8 and 10. One of the arms 14 may be bifurcated.

[Also in Division G2] A disposable toner refill container for an electrostatographic copying machine is formed with an outlet for toner and provided internally with repetitively movable means for supplying a metered amount of toner through the outlet on each repetition of said means. One embodiment shown in Fig. 1 comprises a container body 11 having a circular floor, a rotatable hollow shaft 14 mounted axially of the floor, and a blade 16 mounted on the shaft and disposed to sweep the floor on being rotated with the shaft, the container having an outlet aperture 17 past which the blade sweeps. The container is seated on a plate 19 of the machine by fitting its hollow shaft 14 over a driving shaft 20. The upper end of the shaft 20 carries a spring retainer link. A second embodiment shown in Fig. 3 comprises a container body 31 formed at its lower end with an outlet bore 32, an axially movable plunger 35 with a neck 18 which extends through the bore, and a boss 39 adapted to seat against the lower end of the bore and held there by means of a spring 36. The toner, with the plunger in the illustrated position, falls into and fills the annular space surrounding the plunger portion 38 within the bore 32. If the plunger is then depressed against the spring 36 the part 39 moves clear of the bore and allows the toner therein to fall. Springs 42 may be mounted on the plunger to reduce any tendency of the toner to pack. A machine adapted to receive such a container-dispenser would have a support means and drive means including a cam for co-operation with the plunger head 37 for periodically depressing and releasing the plunger.
