Title: Improvements in and relating to variable-speed driving mechanism
IPC: F16H61/02
Filed: 1935-05-16
Abstract: 451,718. Variable-speed mechanism. SCHUMAKER, J. S., 189, Murdock Avenue, Asheville, North Carolina, and SCHUMAKER, A. G., 446, South Main Street, Haverhill, Massachusetts, both in U.S.A. May 16, 1935, No. 14377. Convention date, May 16, 1934. [Class 80 (ii)] An automatically variable transmitter comprises a universal joint 6, 8, a flywheel ring 4 oscillated thereby, and a planetary gear 10. The ring 4 is pivoted about a diameter upon radial arms 5 upon a driving shaft 1 and about a perpendicular diameter upon arms 7 upon an intermediate shaft 3 supported in a drum 16 so as to have constant angularity. The gear 10 fast on the shaft 3 is in constant mesh with an internal gear 23 normally made fast with a driven shaft 20 by a dog clutch 22. As the shaft 1 rotates, the shaft 3 is also rotated, and at each half revolution of the shaft 3, the ring 4 would be rocked from its mid position of Fig. 1 to its extreme position of Fig. 1a, and back to its mid position. Since, however, the ring 4 is rotating, it resists being rocked in this way and applies a torque to the arms 7 which swings the shaft 3 in a conical orbit carrying the gear 23 with it. With a light load, the shaft 3 will swing in a conical orbit on solid drive. As the load increases, the pinion 10 rolls backwards on the resisting driven gear 23, and increased torque or reduced speed is maintained by the resistance to rocking of the ring 4. Increase of speed of the shaft 1 tends to restore the solid conical drive. The result is an elastic drive responsive both to driving-shaft speed and to driven shaft load. On applying a brake 19 to the drum 16, the conical motion is cut out and a definite low speed results. The mass of the ring 4 is preferably heaped up over the ends of the arms 7 where it is most effective. Reversal of drive is effected by shifting the clutch 22 to engage a central loose gear 24 instead of the gear 23.

Title: Selectors for telephone switching and like purposes
IPC: H01H63/22
Filed: 1948-05-28
Abstract: 653,025. Actuation of switches. STANDARD TELEPHONES & CABLES, Ltd May  28, 1948. No. 14450. Convention date, Aug. 26, 1947. [Class 38(v)] [Also in Groups XXIV and XXXIX]  In an electric selector switch a brush carriage is reciprocated over a line of contacts by a double toothed rack 1 which is driven alternately by each of a pair of pinions 15, 16 the change over of which is effected by a clutch mechanism as the brush carriage reaches each end position. A flexible toothed wheel 27 drives a shaft 26 carrying two arms 29, 30 for driving a pair of toothed wheels 22, 23 mounted freely on the same shaft and permanently meshed with the two pinions 15, 16 for driving the rack to the right or left respectively. The toothed wheels 22, 23 are driven by a pin 46, 53 on one of the appropriate driving arms engaging a notch 47, in a catch 37, 38, on the side of the wheel 23, 23. Change-over of the drive is effected by a sprung pivoted finger 29, 30 which carries the driving pin engaging a roller stop 49, 52, thus causing the pin 46 to be lifted from the groove 47 and the pin 53 to be lifted into the groove the catch 38 on the other toothed wheel. Whilst either toothed wheel is driving the rack the other toothed wheel is driven in the reverse direction via the driving pinion, the rack and the idle pinion, so that at the completion of the-rack travel, the catch .37, 38 on the non-driving toothed wheel is in position to receive the appropriate pin. In order that the pin 46, 53 does not foul its appropriate catch during the reverse rotation, the finger carrying the pin 46, 53 is pulled by a spring 43 against a stop 45 on the arm.
