Title: Rotary impact wrench
IPC: B25B21/02
Filed: 1951-12-31
Abstract: 722,611. Claw clutches; slip couplings. MAURER, S. B. Dec. 31, 1951 [Jan. 5, 1951], No. 30462/51. Class 80 (2) [Also in Group XXII] An impact wrench has frictional driving means provided between its motor and the hammer in order to allow slip as the motor decelerates when the hammer imparts a hammer blow to the anvil and so protect the motor from shock loads. As shown in Fig. 1, the motor is of the sliding vane pneumatic type having an eccentrically-mounted rotor 28 driving a hollow shaft 31 through a rubber sleeve 32 which, by means of a collar 33 tightly fitted on the shaft, is compressed sufficiently to provide a drive except during periods of rapid deceleration of the hammer. The hammer 48 is slidably splined to a spindle 49 and has a single clutch tooth engaging a single tooth on the anvil 37. An air space 53 for moving the hammer forward and an air space 55 for retracting it are formed between the hammer and the spindle and air is supplied to them through the hollow shaft 31 under the control of a centrifugally-operating valve 60. Air is supplied to both faces of the valve 60 but the larger area of the outer face of the valve causes it to be biased slightly inwards, in which position, if the hammer and spindle are rotating only slowly, air is supplied to both spaces 53 and 55, but since the space 55 is greater than the space 53, the hammer is withdrawn from the anvil so that it may speed up. As the hammer speeds up, the valve 60 moves outwards under centrifugal force and causes the space 53 to be vented to atmosphere through openings 73 and through the bore 70 of the spindle 49 and through the anvil, thus allowing the hammer to move forward and deliver a hammer blow to the anvil. Grease is supplied to the clutch mechanism through a nipple 80, several holes 81 in the bushing 38 and a single hole 82 in the anvil. In the modification shown in Fig. 8, the slipping drive is provided by a taper surface 36 on a driver 35 splined to the motor shaft 31 and pressed into engagement with a corresponding taper surface in the hammer 85 by a spring 40. Clutch pin 89 slides axially in the hammer and is connected by a slot and projection 94 to a piston 86. Air spaces 97 and 100 on either side of the piston are supplied with air under the control of a valve 93 operated by a radially sliding weight 88, Fig. 9. When the motor stalls, the air pressure from a port 98 connected to the air space 97 forces the valve to the right, uncovering the port 99 and supplying pressure to the space 100 to withdraw the clutch pin from the tooth 96 on the anvil 90. The motor and hammer then accelerate but, before one revolution is completed, centrifugal force moves the weight to the left and cuts off the supply to the space 100, thus allowing the pressure in space 97 to move the clutch pin forward again.

Title: Programme Control System for Current Consuming Units
IPC: D06F34/08

Abstract: 1,191,197. Washing machines. HOLZERPATENT A.G. 26 June, 1968 [12 July, 1967], No. 30520/68. Heading DIA. [Also in Division G3j A programme control system for current consuming units, e.g. those of an automatic washing machine comprises separate programme switches, e.g. switches 7, 8, 9 independently controlling the units such as washing and spinning motors 13, 14 and a door releasing electromagnet 15, the switches being actuated by a programme control member, e.g. a control drum driven stepwise by a timing motor 3 energized via switches 5, controlled by a timing device providing stepping pulses, and a switch, e.g. a silicon controlled rectifier 62 (Fig. 2, not shown) in series with the programme switches and controlled by the stepping pulses of the timing device and by a delay device with a delay time. not much greater than the duration of a single stepping pulse and adapted to de-energize said units whilst two or more stepping pulses are applied in uninterrupted sequence to the programme control member. In the illustrated embodiment the silicon controlled rectifier (62) is comprised in a control circuit 6 which also includes as the delay device a capacitor in parallel with a resistor. When the switches 5 are open the capacitor is charged via a resistor 4 and a diode rectifier and applies voltage to the collector of a transistor which receives a pulse at its base when a switch 5 is closed and conducts to trigger the silicon controlled rectifier. Closure of a switch 5 for the duration of a stepping pulse, e.g. 0.7 seconds, short circuits the resistor 4 but the transistor is maintained conducting by the discharge of the capacitor for a slightly longer period, e.g. 1 second. Thus during normal operation of the system the capacitor is re-charged at the end of a stepping pulse, and the silicon controlled rectifier again rendered conducting when the next stepping pulse occurs after a programme interval. A switch 5 may, however, be manually operated to drive the timing motor 3 to actuate the switches 7, 8, 9 in a direct succession of steps. Then at the end of a period, e.g. of 1 second, during which 'the capacitor has discharged sufficiently to render the transistor and thereby the silicon controlled rectifier non-conducting, no voltage is applied via the terminal 61 to the switches 7, 8, 9.

Sliding valves; seats and faces. - Valves of the sluice type are provided with a spring- controlled sleeve within the pipe which covers the valve seatings when the valve is withdrawn. A sleeve 2, Fig. 1, is controlled by a spring 4 housed in a recess 1. The valve disc is retained within a ring 5, which is bevelled at 7, and the sleeve is also bevelled at 8. When the valve is lifted into the open position by turning the hand-wheel 11, the sleeve 2 is pushed forward by the spring 4 so as to close the opening left by the valve and provide a continuous passage for the fluid. In a modification, Fig. 4, the valve is made with two discs 15, 16, which enclose two sleeves 12, 13, which are pressed apart by a spring 14. The sleeves are enclosed by a ring 19 held by a bolt 20. When the valve is withdrawn, the sleeves 12, 13 are forced apart so as to cover the opening left by the valve. The valve faces and seats may be ground without removing the valve chest from the pipe line by making the disc 5, Fig. 1, in halves. The lower half and the valve disc are placed in position, and the valve is turned by means of a number of small holes around its circumference. The valve is kept against its seat., by the pressure of the spring 4.
