Title: Improvements in or relating to electric switches
IPC: H01H19/12
Filed: 1936-03-18
Abstract: 472,399. Master control of D.C. motors; looking controllers ; switch contacts. GENERAL ELECTRIC CO., Ltd., and CROFT, E. H. March 18, 1936, No. 8122. [Classes 38 (iii) and 38 (v)] A switch adapted to short-circuit a resistance which is also adapted to be short-circuited step-by-step by switching means, comprises a biassed contact actuating element carrying the movable contact and moved against the bias by an operating cam, an interlock being operated by movement of the actuating element to ensure that the switch is closed before a certain operation of the switching means can occur. A power operated cam-shaft 2 when rotated permits a spring 6 to operate an arm 4 pivoted at 5 to move a contact 3 into engagement with a fixed contact 10. The contact 3 is mounted on a member 7 pivoted on the arm 4 and biassed by a spring 8. At the end of the contact closing movement, the member 7 engages a projection 9 on the arm 4 and is moved positively. Interlock contacts 11 are carried by a rod 12 pivoted at 13 on the arm 4. The invention is described in connection with a series parallel system of motor control employing switching means which control resistances connected first in the motor armature circuits, and then across the motor field the system including two two position groups of switches which may be positioned in like and unlike positions to give a series connection of the motors, a parallel connection, a connection in which the parallel circuits are completed independently of the control resistances and their associated switching means, and a connection for field weakening. A series switch which short-circuits the resistances at the end of the series stage and switches which shortcircuit the resistances at the end of the parallel stage are arranged in accordance with the invention and their interlock contacts operate a catch to prevent movement of the resistance switching means on from their final to their original positions unless these switches have been closed.

Title: Improvements in secret combination electric switches for ignition and other circuits
IPC: B60R25/04
Filed: 1934-03-21
Abstract: 435,197. Secret contact-combination switches. BROOKER, T. E., 15, Manor Lane Terrace, Lee, London. March 21, 1934, No. 8796. [Class 38 (v)] A secret combination switch comprises a number of multiple contact switches A, A<1> the contacts 0, 1, 2 .... 9 of which are connected by wires to the contacts 0, 1, 2 .... 9 of an equal number of switches C, C<1> arranged some distance away. The switches A, A<1> are set to some predetermined position, and a circuit between two conductors E, F can then only be completed when the switch arms C, C<1> are placed on corresponding contacts. The switches C, C<1> may be mounted on the dashboard of a car. The switches A, A<1> are mounted on a device W, Fig. 5, being retained in position by a cover, not shown. The contact arm A or A<1> is mounted on the opposite end of a spindle to the indicator and operating handle B, and, as shown in Fig. 1, the arm and indicator may be at an angle to each other so that the indicator does not indicate the actual number of the contact engaged by the arm. To close the circuit the switches C, C<1> must therefore be moved on to numbers in which this error, known only to the owner, has been allowed for. As a further precaution an earthed conductor R is included in the bundle of wires forming the cable connecting the switches so as to prevent completion of the circuit E, F, by short circuiting all the wires. The switches C, C may be similar to the switches A, A<1> or may take the form of drums.

Title: Improvements in or relating to article gripping means
Inventor: JAMES DAVID RICHARD
IPC: B66C1/02
Filed: 1960-03-14
Abstract: 972,612. Suction lifting devices. MURRAY CURVEX PRINTING Ltd. March 2, 1961 [March 14, 1960], No. 8857/60. Heading B8H. The lifting movement of a member 25, Fig. 1, allows a spring 13, previously compressed by the member 25, to raise a piston 8 and thus produce a drop in pressure within a suction head 18 in contact with an article to be lifted. A washer 11 allows air to escape from the cylinder as the piston moves downwards, but forms an air-tight seal as the piston moves upwards. A spring 13a assists the spring 13 by cushioning the inertia effect produced by the lifting movement, thereby enabling the vacuum to be maintained. The article is released by a pulse of compressed air controlled by an automatic valve 23 and admitted through a conduit 22. Alternatively, a valve may be provided in the assembly itself which connects the cylinder to atmosphere. Fig. 2 shows an alternative construction of suction head.

Title: Improvements in or relating to driving mechanism for perforating or other machines
IPC: F16H9/22
Filed: 1925-04-03
Abstract: 254,780. British United Shoe Machinery Co., Ltd., and Groldbourn, J. April 3, 1925. Expanding-pulley gearing comprises a small round band 51 passing over a driving expanding pulley with interpenetrating cone flanges 17, 21 over a driven pulley 53 of fixed diameter, and over a weighted or like tensioning jockey 65. The invention is specially applicable to shoe-upper perforating-machines. The tread members 17, 21 turn loosely upon a shaft 7, which is secured at one end to a supporting bracket 3 under a work table 1, and is bored for lubrication. The tread member 17 is driven constantly by a band 11<11> engaging a pulley 11 upon the member, which tread member thus drives the other member 21. An elbow lever 37 supported on a bracket 31 on the end of the shaft 7 is controlled by a treadle link 45 and is connected by a link 49 to a suitable trip declutching-device 55, which functions automatically at a definite point in the cycle of operations. When the machine is to be started, the treadle is depressed. The machine is clutched in, and afterwards the lever 37 acts to thrust the pulley flange 21 to the right to increase the speed as desired. When the machine is to be stopped, the treadle is eased, and the lever 37 moves back, allowing the flange 21 to move outwards against a fixed washer 32, so that the machine is driven at a definite low speed. The trip device 55 is now free and acts to declutch at the proper moment to stop the machine in a definite position. To simplify construction, the drive from one pulley flange to the other is adapted to take place at a definite point. A plate 24, Fig. 3, is fitted for the purpose, or accurately-fitting pins might be used.
