Title: Improvements in or relating to tools operated by electric motors of the oscillating armature type
IPC: H02K33/04
Filed: 1948-03-05
Abstract: 651,083. Oscillating machines. BROWN & SHARPE MFG. CO. March 5, 1948, No. 6896. Convention date, March 20, 1947. [Class 35] A vibratory electric motor for operating hair clippers &c. comprises an E-shaped electromagnet 18, a vibratory armature 28 connected to impart vibratory movement to the clipper cutter member or other implement and a vibration absorbing element 64 vibrating in opposition to the armature 28 and arranged to limit vibration amplitude of the latter by means of rubber bumpers 74, 76. The electromagnet 18 has three pole pieces 20, 21, 22 and is supplied with A.C. The armature 28 is a U-shaped permanent magnet supported by two leafsprings 40, 42 rigidly connected at both ends to the legs of the magnet 28 by blocks 44 and to the casing 10 by screws 52 respectively. Connected to the magnet 28 is a flat spring driving member 30 having a pair of driving lugs 32 which engage the moving blade member 14. The vibration absorbing element consists of an I-shaped weighted member 64 projecting upwardly between the legs of the magnet 28 and is formed at its lower end with rearwardly extending arms 66 connected by means of a pair of leak springs 68, 70 to the bosses 48, 50 on the casing 10. These springs 68, 70 are mounted parallel to the springs 40, 42. The armature 28 together with the movable blade 14 makes one complete oscillation for every cycle of the A.C. input to the electromagnet 18. While the armature vibrator is tuned to oscillate at the same rate as the supply A.C. frequency, the element 64 is tuned to be responsive to vibrations tending to be set up within the casing and vibrates in opposition to the armature 28 in order to damp out said vibrations in the casing.

Title: Improvements in or relating to safety control means for cutting and like machines
IPC: F16D67/02
Filed: 1939-03-03
Abstract: 523,135. Safety devices for machines. KODAK, Ltd. March 3, 1939, No. 6981. Convention date, March 4, 1938. [Class 80 (iv)] A cutting or other machine is provided with u clutch having a pair of manually-operable control members requiring the use of both hands of the operator for starting the machine, and with a gravity-applied brake which is independent of the clutch and which is connected to a piston, to the cylinder of which pressure fluid is supplied, so as to disengage the brake, upon operation of the two control members. In the cutting machine shown, movement of the knife 3<1> is effected by a shaft 16 through cranks 18 and rods 17, the shaft 16 being driven from a main shaft 8 through gears 12 ... 15 and an electro-magnetic friction clutch 24 controlled by a pair of normally-open switches 90 in series. The parts 25, 30 of the clutch are associated respectively with the shaft 8 and with a sleeve 23 journalled thereon, while the brake comprises a fixed part 45 and a coned part 41 which is slidable on the sleeve 23 under the control of a lever 59 and which is drivingly connected to a flange thereof by flexible pins 46. The brake is normally engaged by a weight (not shown) acting on the lever 59 through linkage including a lever 54 co-operating with a piston 65 located in a cylinder 64 to which pressure fluid may be supplied under the control of a valve 73 actuated by an electromagnet 77. The arrangement is such that, upon closing the two switches 90, the clutch 24 and the magnet 77 are energized so as to effect respectively the starting of the machine and movement of the valve 73 to supply pressure fluid to the cylinder 64 to actuate the brake-releasing lever 59. Switches 82 controlled by cams 85 on the shaft 16 are provided to enable the switches 90 to be released when the knife is at the bottom of its stroke, these switches 82 being opened, to stop the machine, when the machine has made a complete cycle. A normally-closed reset switch 86, operated by a further cam 87 on the shaft 16, operates.to prevent a repeat stroke of the knife if the switches 90 are held closed. The switches 90 are guarded by a sliding plate 92 which is moved manually to expose the switches before starting the machine but which is returned automatically at the end of the cycle so as to remove the operator's fingers, if necessary, by a cam 111 on the inside face of the gear 15. Further, a stop pin 113 is associated with the plate 92 for engagement with a stop on the gear 15 to prevent a repeat stroke. In a modification, the clutch is actuated by pressure fluid through levers, control being by a pair of manually-operable valves.

Title: Improvements in reciprocating fuel injection pumps including means for varying the advance of injection
IPC: F02M41/12
Filed: 1965-02-19
Abstract: 1,103,121. Fuel injection pumps. ROBERT BOSCH G.m.b.H. Feb. 19, 1965 [Jan. 5, 1965], No.7357/65. Heading F1A. In a fuel injection pump a hydraulic piston jack 31, Fig. 2, varies the fuel delivery advance, a shuttle piston 10 simultaneously varies the engine fuel supply and the spill-off from the control circuit of the hydraulic jack whereby the spill-off increases as the engine fuel supply decreases. An engine-driven gear or blade pump 38 feeds pressurized fuel to spaces 3 which have a leak orifice 39 controlled by a spring-loaded piston 42 to moderate the pressure variation in accordance with pump speed. A conduit 4 feeds fuel to a cylinder 2 which is filled at the b.d.c. position of a double piston 2, 17. An engine-driven shaft 24 which coacts through a fork 26 and rollers 27 with a cam 29 causes axial reciprocating and rotational movement of the pistons 2, 17. A groove 7 supplies fuel through a series of conduits 5 having non-return valves 6 to the fuel injectors during the delivery stroke of the pistons 2, 7. Fuel injection is terminated when the shuttle piston 10 moves to the right to allow spill through a conduit 8a, groove 11 and conduits 8b, 14 to a low pressure area in casing 15 and thence through conduit 15a to the reservoir. During the delivery stroke of piston 2, 17 pressurized fuel is delivered by piston 17 through conduit 19 and non-return valve 20 to space 9 to move the shuttle piston 10 against spring 13. On the return stroke of shuttle piston 10 fuel from space 9 is returned through throttled passage 22 to cylinder 16. At speeds above a predetermined minimum shuttle piston 10 is prevented from returning to its initial position of rest by the liquid present in space 9 and this controls the shuttle piston position at the end of the outward stroke thereby controlling fuel delivery in accordance with engine speed. Injection advance. Space 3 is connected through a conduit 32 to the cylinder 30 of the spring-loaded jack piston 31, Fig. 2, which rotates cam 29 through a fork 34 to advance the beginning of injection. The pressurized fuel in space 3 and cylinder 30 which pressure varies according to the engine speed is connected through conduit 45 and shuttle piston groove 46 to conduit 14. In a modification the groove 46 is replaced by an axial passage 47, Fig. 4 (not shown) connected to a transverse passage. The shape of the openings to conduit 14 and passage 47 may be modified to give any desired law of variation between spill and injection rate, in particular to compensate or over-compensate for the reaction produced by the fuel pressure acting on pistons 2, 17 which tends to oppose the advance of injection. By this means a greater advance may be obtained at high loads than at low loads.
