Abstract: 177,692. Reichard, C. March 15, 1921. Lock-mechanism, slider-type.- In a sliding tumbler lock, a non-rotating key has wave-faces for depressing the projections of the tumblers clear of the gates in the bolt, while a wedgeshaped side piece of the key protrudes or retracts the bolt as the key is inserted. The tumblers are arranged one behind the other in a recess in the bolt and projections b are pressed into gates g in the bolt by springs k. The gates g have a number of side notches for locking the bolt in various positions of protusion. The key c has a series of strips, one corresponding to each tumbler, the strips having wave-like surfaces e, e<1> for depressing the tumbler projection out of the side notches of the gates g. As the key is pushed into the key-slot f, the tumblers are intermittently released from engagement with the bolt at the points n where the crests of the wave faces e and e<1> cross, and the side-piece d pushes out the bolt. The piece d has successive edges inclined and parallel to the direction of insertion of the key in order to push out or retract the bolt step by step, as the tumblers are intermittently released and allowed to re-engage by the wave faces e, e'. The bolt is retracted by inserting the key with the side-piece d on the side opposite to that used for protrusion of the bolt. In the form shown in Fig. 3. the side-bit d of the key moves an auxiliary bolt i which move the the main bolt a by means of the lever h.

IPC: B60Q1/14
Filed: 1954-03-19
Abstract: 747,519. Switching systems for motor vehicle lamps. MOORE ELECTRONIC LABORATORIES, Inc. March 19, 1954, No. 8155/54. Class 38 (4). [Also in Groups XXXVII and XL (b)] In a control system for the high- and lowpowered-filaments 50, 52, respectively, of motor vehicle headlamps, of the kind wherein a driver-operated ratchet switch 60, 63-65 allows either the low-powered filament to be permanently energized from the battery 10, or the two filaments to be selectively energized over a relay 32, 34 controlled by a photoelectric unit 30 responsive to the intensity of light in the vicinity of the vehicle, the switch is provided with auxiliary contacts 74, 76 which are operated by light pressure on its actuating member 60 insufficient to move the change-over contact 65. The auxiliary contacts, disable the automatic control system, by short-circuiting, or open-circuiting, the relay coil 32 so long as the light pressure is maintained on member 60, thus causing the relay to energize the high-powered filament-say for signalling purposes-even although the ambient lighting may be such as to have caused the automatic control system to have selected the low-powered filament. In a modified arrangement, a manually operated change-over switch allows permanent energization of the high-powered filament over a circuit independent of the relay. The auxiliary contacts 74, 76 may be mounted in a housing which clips to, and forms an extension of, the footactuated operating member of the usual ratchet switch. Alternatively, the auxiliary contacts may be directly operated by the actuating pawl of the ratchet switch.
