Patent GB-203687-A (GB)
Abstract: 203,687. Bourquin, E. J. Sept. 6, 1922, [Convention date]. Tune barrels; driving, setting, and changing; tune indicators for; actions, mechanical. - An automatic piano comprises a number of interchangeable pin-barrels driven by planetary gearing and adapted to be brought, by hand, into playing position. The pins are arranged in helicoidal lines on the cylinders to obtain longer tunes without increasing the diameter cf the cylinders. The pin-barrels 14 are interchangeably supported by centring and driving studs 6<a>, 6<b> and compressible points 16, on end-discs 3, mounted on a sleeve 2 keyed to slide on a shaft 1, and are driven by planetary pinions 7 rotated from a motor-driven pinion 13 by gear-wheels 12, 8 mounted on a sleeve 10 connected to, but turning independently of, the sleeve 2. The necessary longitudinal movement is given to the barrels by a comb 17 engaging a screw-thread 10<a> on the sleeve 10, a spring 18 being compressed by the end-disc 4. Disengagement of the comb 17, enabling the spring 18 to return the barrels to their initial position, is obtained at the end of a tune by the engagement of a finger 12<a> on the gear-wheel 12 with a projection 21a on a. stud 21, thereby rotating the stud, which is connected to the comb by a wire 19. To. change the tune, a crank-shaft 31, pivoted to a part 32 on the shaft 1, is moved against the action of a spring 36, so as to remove a peg 34 from a hole 35 and to place it in another hole, these holes being marked with the titles of the tunes, thus rotating the shaft 1. In withdrawing the peg 34, a lever 30 is operated which is connected to a lever 28 operating a wedge 26 so that the comb 24 on which the levers 23 coacting with the pins 14<a> are mounted, is raised by springs 27 to withdraw the points of the levers 23 from the pins 14<a>. The comb 24 carrying the levers 23 is also raised at the end of a tune by operation of the lever 28 by means of a rod connecting it to the stud 21, the movement of the rod being also utilized to stop the motor. The hammers c are actuated by the levers 23 by means of beams 42 and ties 41, 43. The beams 42 are moved longitudinally by means of pins 42a which are brought into the path of teeth on a cylinder 46 rotated from the gear wheel 12, thus first withdrawing the hammer c and subsequently, when released, allowing it to strike the string under the action of a spring 42<b>. The pins for trills are of less than normal height. The pins may act directly on the hammers.

Abstract: 353,227. Variable-speed gearing; mechanical controllers for electric motors. PIEPKORN, A., 439, Metropolitan Avenue, Brooklyn, New York, U.S.A. July 7, 1930, No. 20566. Convention date, July 22, 1929. [Class 80 (ii).] Variable-speed gearing comprises epicyclic trains D, E, F and a corresponding number of ratchet devices controlled from an auxiliary variable-speed motor so that the trains D, E, F are operative three, two, or one at a time. Secured to the driving-shaft a are bevel sun gears 1<1>, 1<2>, 13 of these three trains and a spur gear 15 constantly driving a countershaft 13. Secured to the driven shaft b is the last sun gear 2<3> of train F. The planetcarrying-drum 4f of train F is connected by a sleeve to the second sun 2<2> of train E, and the drum 4<e> of train E to the second sun 2<1> of train D. These drums are loose and geared to pinions 18 loose on shaft 13 and having ratchet faces 19 engaging like faces on pinions 18<a> meshing with gears 6 loose on a control shaft c<a>. Each gear 6 is connected to a companion loose gear 12 by one of three epicyclic trains A, B, C, the planets of which are carried by shaft c<a>. The gears 12 mesh with pinions 20 fast on shaft 13. Shaft c<a> is driven by an auxiliary variable-speed motor which controls the speed of the driven shaft. The arrangement is such that the ratchets 19 allow the trains D &c. to become inoperative in succession, when one drum cuts out, the next starts to be driven by the auxiliary train B or C. The Specification as open to inspection under Sect. 91 (3) (a) describes also a similar arrangement of multiple epicyclic trains and ratchets in which the speed of the driven shaft is varied by adjusting the braking applied to a countershaft. The brake is applied by a reversible electric motor controlled automatically from the driven shaft to drive the latter at constant speed. Three electric wires dip into a cup of mercury revolved by said shaft. The level of the mercury in the centre of the cup varies with the speed, and normally two wires are bridged. When all wires are bridged, the motor turns one way, and when no pair of them is bridged, the motor turns the other way. Relay and switch gear is comprised in the electric circuits. This subject-matter does not appear in the Specification as accepted.

[Class 44.] A fastening, particularly for motor-vehicle bonnets, comprises a sliding member adapted for hooked engagement with a co-operating element, the sliding member being connected to a rotatable crank only by a spring, which acts to retain the sliding member in the locking position and the crank against a stop. In the constructions shown, the sliding member 13 is hooked to engage a keeper 11, and is guided by a channel 18. In the first form, Fig. 2, a helical spring 22 is attached at one end to a stud 23 on the member 13 and at the other end to a crank 16 rotating in a bearing in the channel 18 and having an operating handle 15. In the position shown, the crank is against a stop formed by the cut-away upper end of one of the flanges of the channel 18 and the spring is relaxed and the hook lowered clear of the keepr ; to lock the fastening, the crank is moved clockwise until it engages the upper end of the other flange of the channel, and the spring is thus stressed to hold the hook in the engaged position. In the second form, the shaft carrying the crank 16 passes through a slot in the sliding member 13, forming an additional guide, and the spring is of V-form. In the engaged position shown, the crank bears against one flange of the channel 18, the other flange being cut down to allow free passage of the crank in the unfastening operation.
