A., 745, City Road, Edgbaston, Birmingham, RAE, W., Wilmar, Noblehill, Dumfries, and AMAL, Ltd., Holford Drive, Perry Bar, Birmingham. Oct. 20, 1934, Nos. 30152 /34, 7045 /35, and 8184/35. [Class 38 (v)] A switch for controlling the electrical circuits of a motor vehicle comprises an insulating casing 46 having fixed to it a flanged metal supporting sleeve 48 in which a lock barrel 51 is mounted for sliding and rotational movement. The lock barrel is formed with an extension 61 provided with a spring-pressed pin 62 which has driving engagement with a hole 63 in a connecting sleeve 59 also rotatable and slidable in the supporting sleeve 48. An insulating contact-carrying ring 64 can slide, but not rotate on the sleeve 59 and carries contacts 65 which are pressed by a spring 86 into engagement with fixed contacts 90 on an end cap 87. Rotation of the lock barrel either by a key 58 or knurled knob 110 rotates the ring 64 to control the ignition circuit. The lock is arranged so as to give three positions. A locked off position, an unlocked off position, and an on position. Surrounding the contact ring 64 is an outer ring 72 having contacts as 73 connected by a ring 76 and co-operating with fixed contacts 97 to control the lighting circuits. The outer contact ring 72 is driven by a handle 77 which has driving connection with a ring 82 carrying pins 78, 79 engaging recesses 80, 81 in the ring 72. The contact rings 64, 72 are interlocked by stops (not shown), so that in the locked off position of the ring 64, the handle 77 can only be turned to switch on parking lights, and the lock barrel must be turned at least to the next position before the headlights can be switched on. Alternatively, the outer ring may control contacts in an automatic starting system. The lock barrel and sleeve 59 are also adapted for sliding movement and when pushed to the right against springs 86, 104, moves a contact disc 102 into engagement with contacts 90, 100 to energize the starter. When the lock barrel is in the locked off position a projection 105 on the barrel engages a stop (not shown), and prevents operation of the starter. In one modification, the lighting control member is omitted. In another modification, the driving sleeve is extended through the end cap and operates a fuel valve.

Filed: 1919-12-06
Abstract: 163,067. Myers, A., Myers, L., Myers, R., and Jacobs, E. Dec. 6, 1919. Pens.-In a hhand-operated fly press, 'for stamping pens, the work is automatically removed from a stationary non-perforated bed by a mechanical or a combined mechanical and electric or magnetic ejector operated by the top toolholder or sliding bolt or the screw of the press or by the handle thereof. In the form shown in Figs. 5 and 7, the ejector 5 is removably mounted in a bar 1, which is pushed forward by a spring 13 against the bed 4 in a guide-block 2 secured to the bolster A by a bracket 3. Mounted in the block 2 is a rocking shaft carrying a slotted lever 7 for withdrawing the ejector, and a pair of arms 25, 15, engaged respectively by a pair of arms 22, 19 projecting from a bracket secured to the holder of the top tool 21. During the downward stroke of the tool, a roller 23 on the arm 22 engages the arm 25 so as to withdraw the ejector from the groove in the bed, a bevelled spring catch 18 in the arm 19 being pushed in by the arm 15 and being then projected out beneath it. As the tool moves upwards, the catch 18 engages the arm 15 so as to rock the shaft to withdraw the ejector further, and when the arm is released from the catch the ejector is forced forward by the spring 13 to eject the pen. In the form shown in Fig. 13, the ejector consists of a lever arm 26 pivoted, together with a lever 30 on a shaft 27 and pressed forward by a spring on the shaft. The lever 30 has pivoted thereto at 31 a spring-pressed catch 32 with a stop joint so that on tha descent of the tool a pin 33 on an arm E projecting downwards from the press handle pushes the catch into the dotted position, but during the ascent of the tool the catch and lever are moved together by the pin to compress the spring on the shaft. On release of the catch, the ejector is forced forward by the spring. In another modification, Fig. 16, having levers 36, 43, 44 arranged similarly to the previous form and operated by a lug 49 on the handle peg E, the lever 36 carries a permanent magnet 35 which is moved into contact with the pen by the lug 49 and withdrawn by a spring 39, the pens being removed from the magnet by a stationary brush 50. In a further modification, Fig. 19, an electromagnet 35, carried by a lever 36 of insulating material, is used. One battery terminal is connected by a wire 55 to the electromagnet and the other terminal by a mine 54 to a U-shaped spring part 52 mounted on a support 53 and in contact with a contact piece carried by the lever 36 and connected to the electromagnet. When the lever 36 is pulled by the spring 39 off the part 52, the magnet is de-energized and the pens fall off. According to the Provisional Specification, the sliding ejector may be retracted by an inclined or like projection from the upper tool-holder entering a hole in the ejector.
