Title: Improvements relating to mechanism for controlling direction indicators on motor vehicles
Inventor: PALMER GERALD MARLEY
IPC: B60Q1/42
Filed: 1950-12-07
Abstract: 694,202. Road-traffic signals on vehicles. RILEY MOTORS. Ltd. Dec. 4, 1951 [Dec. 7, 1950], No. 29953/50. Class 118 (ii). The actuating lever 7 for operating a vehicle direction indicator electric switch 1 mounted in the steering wheel boss 2 is normally latched to move rigidly with the steering wheel and independentfy of the switch 1 and hence may be made long enough to be operated from the rim of the wheel without danger of trapping the driver's fingers between, the lever 7 and steering wheel spokes 9, means being provided to unlatch the lever 7 for limited movement with respect to the steering wheel, said movement establishing a driving connection to operate switch 1. The switch 1 accommodated within the hollow boss 2 of the steering wheel by mounting on the static tube 3 of the steering column assembly is of known type adapted to be automatically restored by the return movement of the steering wheel on completion of a turn. Instead of a finger lever, however, the operating spindle 4 carries a driving disc 5 which has notches 6 around its periphery and is frictionally pre-loaded by a blade spring 5a so that it slips at a .given applied torque. The actuating lever 7, which extends over the greater part of the inner radius of the steering wheel, has an annular hub-like part 13 mounted rotatably on a supporting cover 8 fixed above the centre of the steering wheel. The lever .7 can be rotated to each side of a central neutral position to an extent limited by stops provided in the cover 8, Fig. 3 (not shown). A plunger 11, radially slidable in a slot 12 in the member 13, is normally held out of engagement with the notches 6 by a circular spring clip 14 which is located in a groove in the member 13 and which engages a recess 16 in the plunger 11 so as to force the outer end of the latter into a co-operating groove 17 provided in the steering wheel boss 2. Consequently the spring-loaded plunger 11 normally latches the lever 7 to the steering wheel, but when lever 7 is rotated to one side of its neutral position the plunger 11 is forced out of the groove 17 and engages the notches 6 to turn the driving disc 5 and operate the switch 1. Subsequent turning of the steering wheel in the same direction permits the plunger 11 to reenter the groove 17 and the lever 7 is again latched to the steering wheel and disengaged from the disc 5. Automatic cancellation of the signal is effected by the return movement of the steering wheel in the usual manner provided for by the construction of the standard switch 1. In the preferred arrangement the member 7 also acts like a horn-ring and is displaceable against the action of a control spring 18 to close contacts 19 and 20 in the circuit of an electrical audible warning system.

Abstract: 305,579. Herzstark, S. J. Feb. 7, 1928, [Convention date]. Adding and subtracting apparatus; adjusting for recording only; printing totals and sub-totals. - A calculating-machine is provided with column counters in addition to the usual line counters, these column counters being disposed behind or below the stationary typing a. n d counting-mechanisms, and being actuated by subsidiary racks linked with the main racks. Totals and sub-totals may be taken from the column counters by operation of special keys controlling the timing of engagement of the selected counter with the subsidiary racks. Fig. 1 shows the invention as applied to a machine having type racks 1 controlled in extent of movement by key-set stops 2 and connected with actuating racks 6 for the usual stationary counter 8. Adjustably mounted on a. bar 12 swung by links 11 from the paper carriage 10 are the column counters 15 adapted to engage the subsidiary racks 20 controlled from the main racks 1 by levers 17 and links 19 co-operating with lugs 20<1> on the racks. The column counters are timed for engagement by means of a cam disc 30, Fig. 2, the periphery of which is engaged by a bifurcated lever 28 carrying rollers 27, 27<1> in contact with a bar 26 secured to the counter-carrying bar 12. The disc is operated during the cycle of operation by means of a lever 32 carrying two oppositely acting pawls 34, 35 and rocked to and fro through 90‹ by a connection 33 with the main crank. The effectivity of the pawls is controlled by dogs 38, 39 mounted on levers 36, 37 pivoted at 31 and controlled in position by notched sectors 40, 41. Depression of a key 42, Fig. 4, rotates the sector 41 to set the lever 37 in such a position as to disable the pawl 35 on the return stroke. Consequently the control disc remains in the position for disengagement of the counter so that the item is not registered. If key 43 is depressed lever 36 is swung up and the two pawls are controlled in such a manner as to produce the engagement of the counter with the racks throughout their movements in order to give a sub-total. If both keys 42, 43 are depressed, as by use of a key 48, both levers 36, 37 are displaced and the control disc is shifted to time the engagement and disengagement of the counter for total-taking. The levers 36, 37 are held in their extreme positions by latches 44, 45. Transfer-mechanism.-The actuating-racks 20 are permitted an extra step of movement at the end of their return stroke when spring-controlled stop-arms 22 are released by latch members 21 shifted at transfer by the transfer teeth 23.
