Title: Improvements in or relating to automatic machines for dispensing soap tablets or thelike
IPC: A47F1/10
Filed: 1925-02-02
Abstract: 251,353. Cramp, R., and Knight, Ltd., J. Feb. 2, 1925. Contents, delivering.-A device for displaying and dispensing soap tablets and like articles consists of a cabinet comprising a magazine for storing the articles, a movable holder for supporting one of the articles under the glass-topped lid of the cabinet, and means operated by the opening and closing of the lid for replenishing the holder when the tablet has been removed. In the construction shown in Fig. 1, (2890/25), the tablets are stored in a spirally wound belt 5 with spacing projections 4. The free end of the belt is carried round a pulley 13 with projections 12 engaging slots in the belt, and is actuated by the lid 24 through the connecting-rod 22, bell-crank lever 21, spring-pressed pawl 19, and the ratchet wheel 18 is attached to the pulley. The holder 27 for the displayed tablet is pivotally mounted on the pulley shaft 14, and, when loaded, moves its other end 28 which is formed with a cam into such a position that the pawl 19 does not engage the ratchet wheel and so prevents movement of the pulley and consequent feeding, of another tablet to the holder. When the displayed tablet has been removed, the holder 27 is raised by a counterweighted lever 29 or by a spring, thus allowing engagement of the pawl and ratchet clutch and the consequent advance movement of the band 5 to supply another tablet to the holder when the lid is shut. The band is held in contact with the pulley and fed into a locker of the cabinet by a spring-pressed jockey wheel 15 which may have a pawl-and-ratchet mechanism to prevent reverse action. A modification is shown in Fig. 1 (6041/25), in which the tablets are arranged in a vertical shoot and are fed singly by a pusher 9 actuated by a lever 14 loosely mounted on the shaft 15 and carrying a gravity pawl 17 by which it is adapted to be connected to a notched quadrant 20 secured to the shaft 15 which is rocked by the opening and shutting of the lid 29 through the connecting-rod 25 and crank arm 24. The holder 22 for the display tablet is pivoted at 23 and carries a cam 21 at one end the position of which controls the engagement of the pawl 17 with the quadrant. When the display tablet is moved, the holder is raised by a spring 32 and allows the operation of the device to feed another tablet to the holder. Lifting fingers 10<a> on the pusher hold up the column of tablets while the lowest is being fed; and a guided and spring- pressed plate 36 carried in advance of the pusher acts, in conjunction with fixed blocks 42', to guide the lowest tablet into correct position when the pusher is withdrawn.

Abstract: 306,480. Siemens - Schuckertwerke Akt.-Ges. Feb. 21, 1928. [Convention date]. Void [Publislied under Sect. 91 of the Acts]. Rotary converters and transformers; indicators, applications of.-In a separately-excited commutator machine the speed is indicated, especially during the starting-up period, by voltage measurement, e.g. by means of a voltmeter connected to the commutator; in addition, a relay device, also connected to the commutator, is used for affecting a change in the starting resistance at a predetermined speed. The Figure shows the use of a relay 10 for changing the starting resistance 8 in the case of a motor-converter 2, 3 separately excited at 9 on the commutating element 2. The relay is connected to the commutator and at a speed below synchronism energizes an electromagnet which removes the bridging contact 11 on the starting resistance 8. The torque is thereby reduced an synchronizing is facilitated without a tendency for the machine to " race " through synchronism. In place of an increased starting resistance, the relay may be arranged to insert choking coils into the starting circuit. In machines in which alternating voltage components may exist at the commutator, the indicating apparatus and relay are provided with damping devices, and in the case of frequency converters the stator has a separate continuous excitation superposed on its alternating-current excitation.
