Title: An improved clutch device
IPC: B60K17/00
Filed: 1927-10-28
Abstract: 304,391. Atha, C. G. Oct. 28, 1927. Clutches, claw; facilitating changing speed.- An auxiliary clutch for facilitating speed-changing and allowing coasting in motor-vehicles comprises driving and driven members, connected respectively to the gear-box shaft and Cardan shaft, and an apertured intermediate rotary member through which the slidabe clutch member must pass in its engaging movement, the apertured member acting as a mask to prevent clutch reengagement while the driven member is overrunning, but being rotated by friction with the driving-member to allow automatic re-engagement when the driving-member begins to rotate faster than the driven member. A spring-pressed sleeve 8, actuated by a fork 30, is splined to a shaft 6, connected by a flexible coupling 5 to the Cardan shaft 4, and normally engages by external teeth 9 the internal teeth 18 on a driving- member 15 secured to a flange 14 on the gearbox tail-shaft 3. The shaft 6 is supported by a ball bearing 13 in a bore 17 of the member 15. A cup-shaped intermediate member 20, revolubly secured on the member 15 by a ring 28, has internal teeth 22 of less width than the teeth 18, and a washer 24 with wider teeth 26. Complete depression of the main clutch pedal 32 applies a clutch stop (not shown) and takes up the lost motion of a pin-and-slot connection 33, 34 to a rod 31 actuating the fork 30, so that the auxiliary claw clutch is disengaged and the gear-box elements are arrested for gear-changing. The teeth 9, 22, however, remain engaged, so that the part 20 is displaced while the shaft 6 overruns the shaft 3. On release of the pedal 32, the clutch spring 12 thrusts the teeth 9 against the overlapping parts 27 of the teeth 26, which prevent re-engagement until the member 15 overtakes the member 8, when the friction of the washer 24 on the part 15 restores the member 20. The overlaps 27, the forward ends 10 of the teeth 9, and the rear ends 19 of the teeth 18 are all bevelled to facilitate re-engagement. To en. gage reverse gear, the pedal 32 is not fully depressed. The Provisional Specification describes a form in which the members 9, 15 are provided respectively with annularly-arranged pins and recesses, the member 20 having arcuate recesses, each drilled through at one end to allow passage of the pins or of a separate series of projections.

Abstract: 225,579. Grimes Radio Engineering Co., Inc., (Assignees of Grimes, D.). Dec. 1, 1923, [Convention date]. Thermionic amplifiers. - Reflex circuits for wireless reception, of the kind described in Specification 204,301, in which radio-frequency currents and audio-frequency currents traverse the valves in reverse order, are modified so as to prevent howling owing to audio-frequency capacity coupling between the coils of the radio-frequency transformers. Fig. 2 shows a two-valve reflex circuit similar to that described in Specification 204,301, except that the telephones or speaker 30 are connected between the anode 8 of the first valve 6 and the radio-frequency primary coil 9. With this connection, the coil 9 assumes a minimum of audio-frequency voltage and is therefore ineffective in transferring audio-frequency potentials to the grid 14 of the second valve 13 through the inter-coil capacity 31. Transfer of audio-frequency energy through the capacity 32 of the second radio-frequency transformer 17 is minimized by connecting one end of the transformer secondary to the filament lead 46. In an alternative arrangement, the telephones 30 are connected in the usual position between the battery 28 and the coil 9, but the secondary 23 of the audio-frequency transformer 21 and its shunting condenser 16 are transferred to the grid side of the coil 12. In a further alternative, shown in Fig. 4, the audio-frequency coil 23 and the radio-frequency coil 12 are connected in parallel in the grid circuit of the valve 13. A condenser 36 blocks audio-frequency currents from the radio-frequency coil 12, and a radio-frequency choke 37 may if necessary be provided in the audio-frequency branch. Similar parallel connections may be arranged for the telephones 30 and the radio-frequency coil 9 in the plate circuit of the first valve. In all cases, the telephones may be replaced by the primary coil of a transformer, the secondary of which is connected to the grid of a power amplifying valve, having a loud speaker or telephones in its plate circuit.
