Title: Improvements in and relating to power hammers
IPC: B21J7/10
Filed: 1925-06-30
Abstract: 255,738. Horman, A. E. June 30, 1925. Power hammers. - The hammer bead of a power hammer is reciprocated and traversed along the anvil by mechanism controlled by a common controlling device. The hammer 18 is pivoted at 20 to a supporting arm 19 swinging on a bar 14 and is connected at 22 to an arm 21 on a sleeve 23 having arms 24 extending alongside the arm 19. A pin 25 extending between the ends of the arms 24 through a slot 29 on the arm 19 carries rollers engaging cams 17 on the machine frame, and a block 26 on the pin engages a spring 28 on the slot 29, whereby the hammer 18 is kept always in vertical position. The hammer is raised by oscillating arms 31, 32 swinging on the supporting bar 14 and connected across their free ends by a cross-bar 33 which engages under the hammer arm 19 and may be secured thereto by a pivoted latch 34. When the latch is unfastened the hammer may be swung up about the bar 14 into inoperative position to permit other use of the anvil 4 without obstruction. The swinging arms are actuated by a rod 45 connected by collars 43, 44, links 41, 42, springs 40 and bands 38, 38<1> to a block 39 eccentrically pivoted at 48 to the shaft of the power wheel 7, which is driven from a wheel 5 by a belt 6 when a jockey pulley 9 carried on an arm 8 of a lever 10 is pressed down to tighten the belt. The lever 10 is pivoted to a horizontal rod 50 provided at the end with a pedal 57 and supported by a link 51. Forward movement of the pedal 57 depresses the jockey pulley 9 and starts the action of the hammer. A spring 55 normally keeps the jockey pulley raised so that no drive is transmitted to the wheel 7. The rod 50 is connected by a cross-rod 54 to another longitudinal rod 52 on the other side of the machine, and the pedal 67 is pivoted on the cross-rod 54 and connected by a rod 58 and link 60 to a weighted lever 62 on a shaft 64. The latter is adapted to actuate a yoke-shaped latch 68 on the hammer member and bring either arm 70 of the latch into engagement with the upper or lower run of a continuously-driven chain 72, whereby the hammer head is traversed along the anvil after giving the pedal 57 a pivotal movement. One of the suspension links 13 of the rod 52 acts as a brake lever for a brake 12 engaging the wheel 7, the pivot of the brake lever being parallel to the axis of the wheel 7 and within its periphery, whereby increased braking effect is obtained. Projections 71 on the latch 68 are adapted to engage cams at the sides of the machine frame so as to disengage the latch from the chain 72 when the hammer approaches either side of the machine.

Title: Improvements in or relating to arrangements for varying the inclination of aircraft controlled in accordance with a gyroscopic horizon
IPC: G01C19/44
Filed: 1938-01-31
Abstract: 510,524. Automatic control systems. SIEMENS APPARATE UND MACHINEN GES. Jan. 31, 1938, No. 3005. Convention date, Jan. 30, 1937. [Class 38 (iv)] Altitude of aircraft about a longitudinal and/or lateral axis is controlled by a gyroscopic horizon instrument 1 which is supervised by means 90, 91 preventing any variation in the inclination of the gyroscopic horizon to the true vertical and so arranged that no displacement of the neutral position of the supervisory means occurs when the altitude controls are adjusted. The instrument 1 actuates an aeroplane model 8 and bolometer shield 11 on its transverse axis 6 and a horizon disc 7 and a bolometer shield 49 on its longitudinal axis 4. Nozzles 12, 50 from which issue air, driven, e.g., by electromagnetically vibrated diaphragms, are directed past the shields towards resistances 13, 51 in balanced circuits respectively associated with the differential windings of rotary magnets 16, 54 which in association with rate of turn indicators 17, 55 actuate the fluid pressure servomotors of elevator and ailerons respectively. Longitudinal and lateral stability are thus maintained but the pendulums 90, 91 co-operating respectively with pairs of contacts connected to differential magnet windings 94, 95 adapted to apply torque to permanent magnets 92, 93 supervise the gyroscope in respect of the true vertical. As shown, the longitudinal inclination of the craft may be automatically adjusted by a member 32 responsive to air speed which controls a reversible motor 41 geared to the mounting of the nozzle 12 which is pivoted about the transverse axis of the gyroscope. To prevent disturbance of the supervisory function of the pendulum 90 by this adjustment it is pivoted on the axis 6 and its contacts are mounted so as to move with the nozzle 12 about the same axis. The transverse axis of the craft, as shown, may also be adjusted when turning by a rate of turn indicator 71 which is coupled to the shield 9 a bolometer 74 connected to the differential fields of a motor 77 geared to the nozzle 50. The transverse supervising pendulum 91, since it responds to the apparent vertical, is self adjusted by the movement of its contacts about the pendulum axis which is produced by the tilting of the craft. The rate of turn indicator shown has its restraint varied inversely as the air speed by means 70 responsive to air speed.
