Title: Rotary impact tools
IPC: B25B21/02
Filed: 1952-01-21
Abstract: 731,255. Clutches. MAURER, S. B. Jan. 21, 1952, No. 1658/52. Class 80 (2). [Also in Group XXII] An impact wrench has an anvil 37 with a radial projection 43, which is engaged by a hammer pin 48 slidable in a hammer 42, and fluid-pressure-operated means, such as a piston 52 or a diaphragm or bellows, moves the pin in at least the direction to cause its disengagement from the projection 43. Compressed air is supplied to the motor 28 under the control of a trigger 14 and a reversing valve 17 and also passes through a conduit 71 and the hollow hub of the motor to a bore 55 in the piston 52. The air pressure acts on the upper face 67 of a valve 58 carried by the piston and moves it so that air passes into the cylinder space 45 and moves the piston rearwardly, withdrawing the pin 48. As the motor speeds up, centrifugal force acting on a weight 61 carried by the valve moves the valve to the position of Fig. 1, closing the bore 55 and opening an exhaust duct 76 so that the pin 48 and projection 43 are again engaged. As the motor slows up under increasing resistance from the nut being tightened, the pressure on the face 67 of the valve overcomes the centrifugal force on the weight and opens the valve, thus withdrawing the pin and allowing the motor to speed up so that a hammer blow is given to the anvil when the valve again closes and causes the pin to engage again. In the modification shown in Fig. 8, fluid-pressure acts only to withdraw the hammer pin 107 and a spring 114 re-engages it. The fluid-pressure is constantly communicated through a bore 104 and groove 103 in the hollow anvil shaft 102 to the cylinder space 109 and the spring value is such that it engages the pin 107 with the anvil projection 43 when the motor is running fast against light resistance but is overcome when the pressure in the piston space rises as the motor stalls or begins to stall.

Title: Improvements in or relating to integrating mechanisms
IPC: G06G3/08
Filed: 1940-01-29
Abstract: 572,598. Integrating - apparatus. FERRANTI, Ltd., GRUNDY, E., CLUDERAY, E. S., and SMITH, P. B. N. NUTTALL-. Jan. 29, 1940, No. 1731. [Class 106 (i)] Automatic mechanism for integrating components of vectorial quantities of the same magnitude in a given direction comprises a measuring device which on occurrence of the quantity moves a first member longitudinally to an extent limited by the relative position of a second member positioned by a direction measuring device, means for returning the first member to initial position after occurrence of each quantity, and summation means for adding uni-directional movements of the first member. An air-log 1, 2 drives through worm gear 4, 5 a cam 3 which makes the circuit of a solenoid 7 every one-tenth mile and causes the armature 8 to be attracted and move pawl 10 to advance the ratchet wheel 12 three teeth. This wheel has 30 teeth and, therefore, it and the shaft 13 thereon makes one revolution per mile. Fixed to the shaft 13 is a half-cylinder 17, one edge of which stands higher than the other. Loose on the shaft is a sleeve 21 having an external rough-pitch thread to which sleeve is secured a one-spoke toothed wheel 25 driving through a long pinion 29 a toothed wheel 32, a pawl 34 on which through ratchet 35 and gears 37 drives the pointers 38 of a counter. The half-cylinder 17 projects through the gap in the wheel 25 and is engaged by a roller 27 carried by the wheel. The end of the sleeve 21 is acted upon by a spring 24 and the sleeve is. surrounded by a cylindrical nut 22, a projecting pin 23 on which passes through a vertical slot 20 in a guide cylinder 18 and engages a cam surface 39 rotated from a motor 41 operated in response to the movement of a compass 42 in the aircraft. The cam is such that the rotation of the cam causes axial movement of the wheel 25 proportional to the cosine of the angle of deviation of the aircraft from a northerly course. The other end of the lever 9 is provided with a pawl driving similar apparatus co-operating with the cam 39 which moves the corresponding wheel proportionally to the sine of the compass angle. In a modification, each of the first members is formed by a rack. Specification 22041 /11, [Class 106 (i)], is referred to.

Abstract: 715,074. Two-part couplings. AIRCRAFT MARINE PRODUCTS, Inc. Jan. 22, 1952, No. 1770/52, Class 38(I). [Also in Group XXII] A pin type electrical connector strip for use in a connector applying machine comprises tapered tubular pins having integral ferrules said parts being shaped from sheet metal the pins having their leading edges converging in towards their axes except for a connecting strip which lies on the opposite side of each pin axis from the abutting edges of the sheet metal of the pin said connector strip joining the pin end of one connector to the ferrule of the next. Each pin connector 2 one of which is to be applied to a lead wire has a round or conical end 6 for insertion into a socket 9 (Fig. 7) mounted in an insulated panel said socket having a guiding trough 10 at its end which is open at the top and spread laterally at 11. Insulation piercing teeth 18 are punched up on the inner face of the ferrule 16 of each connector to ensure a good electrical contact with the lead wire when the ferrule is crimped on the wire. In applying the connectors to the ends of lead wires the strip is fed. between guides 19 until the end connector is in position shown.in Fig. 3. The press head carrying a crimping die 24, a shear plate 30 and a pusher plate 42 moves down and the part 34 of the shear plate 30 centres the connector strip I2 with respect to a forming notch 48 and positions the end edges of the ferrule 16 of the adjacent connector which is pressed against the rear face of the shear plate 30 by a spring detent 3I. As the shear plate 30 begins to shear the strip I2 the pusher 42 engages the tip of the connector pin and thus shears the strip at the tip 6 of the pin the strip being tensioned as it is pushed down over the edge of the anvil 44. Final movement of the press completes the crimping of the ferrule between the dies 24 and 22 and the end of the pin is pressed into the forming notch 48 which wipes or burnishes the tip. The pusher plate 42 is provided with a recess 54 which receives the sheared connector strips and from which they are discharged laterally by an air blast.
