Title: Improvements in or relating to the manufacture of typewriters
Inventor: TAYLOR CHARLES WILLIAM
IPC: B23K1/00
Filed: 1960-11-17
Abstract: 970,709. Making typewriters; shearing. T.S. PRECISION ENGINEERING Ltd. Feb. 19, 1962 [Nov. 17, 1960], No. 39495/60. Headings B3A and B3W. A method of preparing a channel section type-piece for its attachment to a type bar comprises positioning a length of solder in the channel and then deforming it to cause it to become wedged in the channel. An apparatus for positioning the solder in the channel comprises a magazine drum 1 which has slots 2 in the periphery to receive the type-pieces. The drum is fixed to a shaft 4 which also carries a ratchet-wheel 5 which is stepped round by a pawl 8, resiliently mounted on an arm 7 which pivots about the shaft 4. The outer end of the arm is oscillated by an air-cylinder 11. A spring-loaded detent 12 prevents reverse rotation of the wheel. A U-section strip of solder 20 is drawn from a drum and is intermittently advanced by a device operated by an aircylinder. The device comprises a block sliding between guides and shaped so that as the block moves forward it twists slightly so that the solder strip which lies in a slot in the block is lightly gripped by the edges of the slot. On the return stroke the block moves so that slot is parallel to the direction of motion and moves freely past the strip. The apparatus also comprises a hammer 31 and a knife 32 secured to the hammer and both are located in a guide block 34, and operated by an air-cylinder 33. A safety device comprising a pivoted arm 35 connected to a micro-switch 38 stops the apparatus if a piece is incorrectly located in the magazine. Type-pieces are loaded into the magazine manually and as each piece is brought to a position the solder-strip, the solder is advanced so that the end of the ribbon projects along the length of the type-piece but spaced therefrom. The air cylinder 33 operates and the knife 32 cuts off a slug of solder which is pushed into the channel of the type-piece by the hammer 31. Specification 970,708 is referred to.

Abstract: 982,127. Parking windscreen wipers. FORD MOTOR CO. Ltd. Oct. 8, 1963 [Dec. 13, 1962], No. 39538/63. Heading A4F. [Also in Division H2] A self-parking windscreen wiper is driven by the armature 14 of a permanent magnet electric motor which is controlled by a switch that can be set either in a "run" position to connect the armature directly to a power source or in a "park" position to connect the armature to the power source through an automatically operated switch which opens every time the wiper is in position for parking so that the motor is then de-energized and the wiper is stopped by the electrodynamic braking force resulting from the field of the permanent magnet of the motor acting on the armature. The armature 14 is rotatably mounted on a shaft 13 in a housing 11 and drives the output shaft 33, connected by linkage means to the windscreen wipers, through a worm screw 35 and gear wheels contained in a housing 34. The shaft 33 carries a cam 45 which once in every cycle of rotation, when the windscreen wiper is in position for parking pushes a lever 81 which thereby moves a push-rod 85 to open the automatic switch whereby, when the dashboard switch is in the "park" position, the motor is de-energized and the wiper parted. An electric circuit is shown and described.
