Title: Improvements in driving mechanism
IPC: G10F1/02
Filed: 1924-08-25
Abstract: 243,429. Coldman, H. C., and Webb. C. F. Aug. 25, 1924. No Patent granted (Sealing fee not paid). Variable-speed gearing of the class in which the speed is varied automatically by easing the engaging pressure between friction gear members controlled by a centrifugal governor on the driven member, comprises a pneumatic relay device by which this pressure is applied. The gearing is for driving the music rollers of automatic piano players, and like instruments. A fly-wheel 9 driven through a worm 8 from a treadle-actuated &c. shaft 1 is formed on its face as a friction disc engaged by a roller 10 fast on a driven shaft 11. The engaging pressure of the roller on the disc is supplied by suction in a chamber 17 behind a diaphragm 12. A centrifugal weight 13 moves outwards when the shaft 11 reaches a maximum speed, and opens a ball valve 16 so that air flows into the chamber 17 and eases the frictional pressure. The roller 10 is driven more slowly, and the drive, may take the form of a series of impulses. The maximum speed is adjusted by sliding a cone 25 from the key-board of the piano. When a rapid drive is to be maintained, the engaging pressure may be produced positively through a lever 31 actuated from, say, the tempo lever.

Filed: 1919-08-19
Abstract: 154,291. Tibbles, H. J., and Gunn, Ltd., T. Aug. 19, 1919. Theft and like alarms.-An alarm for use on motor vehicles or boats, of the kind in which an electric signalling - device is operated when the steering-wheel is moved, consists of an electric bell A, B, C with an ordinary ringing-circuit comprising a battery 0, switch K, lead L, electromagnet B, and lead N, together with a control circuit which includes the switch K and lead L but not the armature C, and which returns by lead D, switch E, resistance G and switch H to a battery J. The device is set by turning the bolt of a lock which closes both switches H, K, and by closing switch E by setting the steering- gear, so that the control circuit causes the electromagnet B to keep the armature of the bell attracted and so keeps the ringing circuit open. The means for closing switch E is shown in Fig. 3. Two members hinged at T with the switch E between them are mounted on the chassis and closed by an arm Z on a link 1 attached to the steering-wheel. When the steering-wheel is turned into position for straight-forward movement, switch E is opened, the control circuit is broken, and the bell rings. The same battery may be used for both circuits but the battery 0 is preferably concealed and the accumulator battery of the vehicle is used as a battery J.
