Abstract: 446,932. Electric clocks. FERRANTI, Ltd., and EASTON, H., Hollinwood, Lancashire. Feb. 28, 1935, Nos. 6367 and 15738. [Class 139] In a synchronous-motor clock having in reserve a time-governed spring motor continuously operating at normal speed, the synchronous motor drives the motionwork through a one-way drive, the reserve motor drives the motionwork through a second oneway drive and means are provided for intermittently or continuously overriding or rendering ineffective the drive from the reserve motor whilst the synchronous motor is operating. Rigid with the clock shaft a are ratchet wheels band c driven by pawls d and e on wheels s and k loose on shaft a. The synchronous motor h drives the train f, g, s to operate (1) the pawl d, (2) a wheel t rigid with sun-wheel q, and (3) a wheel m for winding a spring motor n, the shaft p of which is controlled by an escapement o and drives, through wheel u, a wheel w rigid with a sun-wheel r. Sun-wheels q and r rotate oppositely and coact with a planet carrier i which drives the train j, v, k to rotate the pawl e. If motor h fails, sun-wheel q is immobilized and the auxiliary movement o, p drives pawl e and shaft a through the differential; but whilst the motor h rotates the wheel q, the effect is to slow up the planet carrier so that ratchet c overrides its pawl e continuously. In a modification, Fig. 2, the synchronous motor h drives the pawl d through gearing f, 2, 3, 4, and winds the spring motor n, and the latter drives the pawl e through a friction device consisting of members 8, 9, 10 and a toothed wheel 11 which is arrested periodically by a lug on the end of an arm 18 rigid with shaft 17 ; the latter carrying also an arm 16 which is rocked by a pin 14 on a disc 13 driven from the synchronous motor h through gearing f<1>, m, 15.

Filed: 1927-03-08
Abstract: 275,506. Fairweather, W. C., (L'nderwood Typewriter Co.). March 8, 1927. Back spacing mechanism.-Relates to mechanism of the kind in which the back-spacing pawl moves laterally into engagement with the rack and then longitudinally with the rack, and consists in the provision of a single spring adapted to move the pawl into engagement with the rack on operation of the back-spacing key, and to return the mechanism to normal position on release of the back-spacing key. The Figure shows mechanism comprising a pawl 37 pivoted at 38 to an arm 39 rocking on a stationary pivot 40, a link 29 being pivoted at 35 to the pawl and being pivoted also to an arm 27 on the shaft 26 of the back-spacing key-lever 25. The mechanism is now provided with a single spring 32 connected to a bracket 34 and a lug 33 at the rear of the link 29, an arm 28 at the front of the link being pivoted at 30 to the arm 27. The spring is initially strained and urges forward the link, but owing to the relative, disposition of the pivots 30, 40 forward movement is normally prevented and the arm 39 is retained in contact with a stop 44. On depression of the back-spacing key 24, the pivot 30 is depressed and the spring immediately moves forward the link, the pawl being thereby moved into engagerrent with the rack 15. On arrest of the arm 39. the continued depression of the key depresses the link and the pawl is moved longitudinally with the rack. On release of the key, the spring returns the mechanism to normal position.
