Title: Improvements in and relating to repeating devices for use with disc record talking machines
IPC: G11B3/095
Filed: 1926-10-27
Abstract: 277,521. Kingston, A. W., and Baxter, P. Oct. 27, 1926. No Patent granted (Sealing fee not paid). Returning sound-box to starting position.-Relates to automatic repeating devices in which the sound-box after playing is reset by sliding under gravity along a pivoted track which is tilted by a member disposed centrally on, and rotating with, the record, and consists in making the centrally disposed member extensible vertically to a limited amount and effecting the extension by interruption of the rotation of one part of the member when the stylus reaches the end of the record. The parts are readily applied to existing machines. The track a, Fig. 1, supported on a fixed pivot b extends over the record and is bent over at its free end a<2> to rest on the end of a screw g engaging a nut in a socket h upstanding from a base disc i engaging the turntable spindle and resting on the record j so as to rotate, therewith. A sleeve n<1> is clamped on the tone-arm o or sound-box p and supports a vertically adjustable rod carrying a roller a<5> and a screwed pin m<1> on which a threaded disc m can, be adjusted. At the end of a reproduction, the disc m rocks a pivoted detent l into the path of spring jaws k on the screw g which is thereby held against rotation with the socket h and consequently unscrews therefrom and lifts the inner end of the track a so that it engages and lifts the roll a<5>, and the sound-box p then descends by gravity along the inclined track to starting position. At this stage, the screw g is unscrewed to its full extent against a collar at its inner end and the spacing jaws are now forced past the detent l which is then swung back by its spring l<2>. The screw g is of such a pitch that it can now screw into the socket h by gravity and thus lowers the sound-box to recommence playing. To secure accuracy at starting, the returning sound-box is arrested by an adjustable buffer s on a screwed spindle r supported in a sleeve q<1> formed by bending round a projection q from the track and engaging by its threads with a spring u which can be sprung out of engagement when desired. In a modification, the buffer s, Fig. 6, is guided in the part a<6> of an L-shaped slot in the track and adjusted by a link s<2> from a bolt t<1> adapted to be clamped on the other part of the L-slot. To facilitate removal, the pivot support c for the track a is mounted on split pin supports e and adjusted by a finger washer f<1> on a screw thread engaging the support and bearing on the fixed plate secured to the gramophone casing.

Title: Improvements in and relating to intermittently operating motors
IPC: H02P5/68
Filed: 1927-10-12
Abstract: 307,715. Smoot, C. H. Oct. 12, 1927. Fluid governors; differential governors. - An electric motor 1 for working a mechanical stoker or other apparatus subject to variable demand is automatically controlled so as to perform the work intermittently, the motor, in the arrangement shown, being switched in and out by a nut 10 which travels backwards and forwards along a screw 9 at a speed depending on the varying speed of a constantly-running auxiliary motor 18 responsive to the conditions of demand, for example steam pressure in a boiler 3. The screw 9 is revolved by the motor 1, so that if the steam pressure remains steady at its minimum value, the nut 10 has no endlong movement and the motor 1 is left continuously in action. If the pressure rises the movement of a diaphragm 25 acting through a pneumatic relay 30 moves a lever 20 which puts more or less resistance in the circuit of the auxiliary motor and thus reduces its speed, causing the nut to travel more or less quickly and, after a given range of travel determined by the amount of lost motion allowed by a member 7, to switch off the motor 1. The nut then travels back and switches the working motor in after a proportionate interval, the cycle of operations recuriing so long as the motor is working below its maximum demand. A centrifugal governor 33 driven by the auxiliary motor acts upon the lever 20 so as to stabilize the regulation. In a modification the moving nut 10 throws a clutch in and out instead of acting on the motor switch.

Title: Improvements in switching means for use in connection with electro-magnetic vibratory devices
IPC: H01H9/26
Filed: 1929-09-09
Abstract: 336,371. Gramophone Co., Ltd., and Radford, A. S. Sept. 9, 1929. Magnetic instruments. -An electromagnetic vibratory device, such as a loud-speaker, having a coil adapted to carry oscillatory currents, such as acoustic currents, and an electromagnet to provide the steady field, is provided with switching means for preventing the flow of relatively large currents through the oscillatory current coil due to the making or breaking of the circuit of the electromagnet. The arrangement is preferably such that the opening or closing of the circuit of the electromagnet is prevented until the oscillatory current circuit has been interrupted. The loud-speaker may be of the moving coil type or the diaphragm may be actuated by an armature co-operating with a fixed coil through which the oscillatory currents are adapted to flow. According to one arangement, Fig. 2, a knife switch b is arranged in the oscillatory circuit and a. tumbler switch d is provided in the steady magnetic field circuit, the switches being so arranged that the handle c of switch b cannot be moved into the closed position until the knob f of switch d has been moved into the " on " position shown in dotted lines. Further, once the switch b is closed, the knob f cannot be moved into the "off'' position until the handle c is raised. Fig. 3 shows a modification in which the two switches are combined in a single device comprising a spring controlled pivoted arm i carrying two contact plates j, k, the plate j co-operating with contacts i in the field circuit whilst the plate k co-operates with contacts m in the moving coil circuit but only after the field circuit has been closed. Figs. 4 and 5 show a further modification in which a drum q of insulating material is provided with four segment-shaped contact strips r, s co-operating with fixed contacts t, u. The strips r are connected in the moving coil circuit and the strips s in the field circuit, the strips being so arranged that when the knob v is moved into the " on " position the strips s co-operate with their contacts t, u before the strips r complete the moving coil circuit. If desired, the desired sequence of contact making and breaking may be obtained by a suitable trip mechanism.
