Abstract: 1,158,788. Actuation of switches. E.M.P. ELECTRIC Ltd. 30 Jan., 1967 [28 Oct., 1965], No. 45665/65. Heading H1N. In a spring actuating mechanism for a circuit breaker, an opening spring 24 and a closing spring 19 are charged successively by successive movements of an operating member 34. The operating lever 34, which may be moved manually, pneumatically, or by electric motor, drives a disc 14 through a pawl 35 engaging projections 37 the pawl being positioned by a fixed cam 36. The disc 14 is first rotated anticlockwise drawing a tension rod 22 to the right to rotate a crank 18; this compresses the spring 24 against a fixed pivot 25 and straightens a toggle 29, 31 which is then latched. The disc 14 is then rotated clockwise compressing the spring 19 against the crank 18 now held by the toggle. This brings disc 14 back to the position shown; a slight further movement moves spring pivot 13 overcentre and either immediately or after releasing a closing latch the spring drives the disc 14 and, through a Geneva-type mechanism 13, 11, a second disc 10 to close contacts (not shown). Subsequent release of the toggle 29, 31 permits spring 24 to open the contacts. The spring 24 may be a two stage arrangement so that the opening motion is slowed towards the end or a dashpot may be provided. The toggle 29, 31 may be released by a solenoid.

Abstract: 1,051,329. Typewriters. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 13, 1964 [Dec. 20, 1963], No. 46261/64. Heading B6F. In a typewriter in which characters are arranged around a cylindrical shell 5 which is axially and rotatively moved to select a character and which cylinder is swung to effect impression, an anvil 3 with a projection 4 is provided inside the shell to concentrate the mass directly behind the character to be printed and so permit the shell to be light in weight. The anvil 3 is attached to the upper end of a tube 2 secured to a tilting base 1 mounted on a carriage. Inside the tube slides an actuating shaft 10 to which the type shell 5 is removably attached by a locating stud 13 and nut 11. The lower end of shaft 10 is rotatively secured in a two-way thrust bearing 16 so that, when the type-shell is being axially set by tube 14, rack 18, pinion 19 and pulley 24, the shaft 10, which is flattened at the very bottom, may also be selectively rotated by a slotted collar 27, tube 26 and a pulley 28. Type - carriage; letter - spacing platen.- Although described in regard to a type-cylinder mounted for travel across a platen the cylinder may be transversely fixed and the platen movable in letter-spacing direction. Aligning for impression.-As the cylinder 5 is being tilted for impression it is locked and aligned in printing position by a ball 34, Fig. 7, which is cammed into a hole 30 by a cam 33 on an actuator 32 sliding in a slot 35 in the anvil 3. In an alternative arrangement the actuator is formed with a wedge which engages in the shell. Uniformity of impression; disposition of character on rotary type-member.-As shown in Fig. 5 the characters with the largest printing areas are positioned on the lower-part of the cylinder, since as the cylinder has to be raised to move these characters into printing position, the moment of inertia of the cylinder is then at its greatest. Type-cylinder construction.-The type-cylinder 5 is thin walled, it is made of metal or plastic or formed with a very thin steel shell on its inner side and a moulded plastic member on its outer side. Case-shift.-Case-shift is effected by a special movement of the cylinder to shift it axially to one half or the other as shown in Fig. 5, or to rotate it 180 degrees as in Fig. 6 (not shown).

[Also in Division G3] In a fluid-pressure operated booster wherein power is generated by the application of differential pressures to the opposite sides of a movable wall under the control of valve means, the latter is actuated by further means incorporating a single member 72 which controls the boost ratio so that changing or repositioning this member allows the changing of the boost ratio without modification of the rest of the assembly. The motor shown comprises a chamber 51 normally connected to a vacuum source and a chamber 53 connectable either to chamber 51 through passage 80, chamber 78, vacuum valve 79, chamber 73 and passages 74- 77 or, when the booster is operated, to an air inlet filter 83 through passages 80, 78 and air valve 81. The valve actuating means comprises a lever 69 provided with a diaphragm 70 dividing two chambers 73, 78, the lever pivoting on the fulcrum 72. On actuation of a master cylinder fluid pressure is applied beneath piston 68 to rock lever 69 clockwise against spring 82, first closing vacuum valve 79 to isolate chamber 53 from vacuum chamber 51 and then opening air valve 81 until the resulting pressure in chamber 78 moves the lever 69 back to close air valve 81. The boost ratio is dependent on the position of fulcrum 72 which is formed on a base 47 removably received in wall 71, a number of such members with projections at different positions being provided whereby the boost ratio may be varied by turning a member through 180 degrees or substituting a different one. In a modification the lever is pivoted on a plate 47 carried on the movable wall and is actuated directly by a rod connected to the brake pedal.
