Filed: 1922-05-04
Abstract: 180,992. Monard, A. May 30, 1921, [Convention date]. Electric operation and control; spring control. - Siding points, reversed when trailed through, are operated by an electric motor which is actuated by high-tension current passing through a solenoid 50, indication of the points being obtained by low tension current which does not pass through the coil 50. The motor 1 is coupled to a rod 5 and lever 6 which engages stops 10, 11 on the stretcher-bar 9, a toggle spring 14 being also connected to the pin 8 that connects the rod 5 and lever 6. The electric motor operates the points through a clutch to permit the points to be trailed through, the motor connections being however reversed at the same time. The motor is controlled by a handle 42 operating a cam 43 which lifts the stem 44 of an armature 48, the armature being retained by its coil 50, which is energized at first through a switch 51 closed by the cam 43 and then through contacts 45 carried by the stem 44, contacts 61 of a fly-over switch 54 actuated by the cam 43, and commutator contact 35 of the motor. Contacts 35, 36 are normally closed, one being opened in each extreme position of the motor, whilst contacts 33, 34 are normally open. When the stem 44 is down, it closes contacts 46 which earth the motor windings through switches 54, 58, and it also closes contacts 47 so that low-tension current passes through the transformer 71, switch 54, and contact 34 or 35 to a coil 62, which obscures the :red disc of a miniature signal and opens the switch 67 of a buzzer 72. The disc is visible and the buzzer sounds when this circuit is broken, that is when the points are half open, when they have been trailed through, or when they have been operated manually by a handle on one of the motor shafts. The points can be reversed in mid-stroke. Two or more control elements can be coupled together and interlocked, the handles 42 operating cams with hollows engaged by the rounded ends of an intermediate rod.

Title: Improvements in or relating to recording apparatus for producing music records for use in player pianos
IPC: G10G3/04
Filed: 1924-05-26
Abstract: 232,064. Hofmann, J. May 26, 1924. Recording m u s i c .- In electrical apparatus for recording the touch employed in playing the pianoforte, a rocking frame extends under some or all of the keys and rotates to various extents a contact drum which meets a gradually increasing spring resistance and is eventually stopped and returned thereby. Preferably one frame 4 extends under the treble, and another under the bass, key 5, the frames being pivoted as at 2 and each carrying an arm 6 which by a band 7 or toothed segment rotates a pulley 8 and the contact drum 12. In the path of a pin 14 on the drum are a number of spring-controlled arms a<1> - -- a<11>, which as thev successively come into action cause a gradually increasing resistance to the movement of the drum. In order to prevent, after a heavy blow, too rapid return of the drum under the spring action, the pin 14 is connected to the piston of a dash-pot 16, which has a tapered slot in its cylinder so that its effective braking-action is greater the greater the pistonstroke, thus ensuring closure of the electric contacts for a sufficient length of time to enable the recording elements to function. Each frame operates four recording devices, the contacts on the drum being arranged in various combinations.

IPC: A63H27/00
Abstract: 129,555. Woodward, J. W. W. Dec. 14, 1918. Table games.-A model aeroplane which can be moved by various means carries balls or weights representing bombs which can be dropped on to an objective by means operated by the player. The aeroplane X, Fig. 1, is suspended from an inclined stretched wire e so that it moves along the wire by gravity. The device for storing the " bombs " j, Fig. 5, consists of a number of shutters or leaves g<3> secured radially to a spindle g' arranged transversely in an opening g in the base of the aeroplane. A small figure c, pivoted in the body of the aeroplane and controlled by a spring f, acts as a detent to retain the shutters until they are rotated by a cord h controlled by the player. Thus as the aeroplane slides along the wire c, the player by pulling the cord h can discharge one or more of the " bombs " on to an objective k. In modifications of the device, the wire c may be horizontal and the aeroplane drawn along it by a cord attached to a falling weight. The wire c may also pass over pulleys which are rotated by clockwork. The " bombs " may also be stored in the compartments of a drawer that can be moved over the opening g. In a further modification, the aeroplane is suspended from an arm secured to a rotatable standard so that the path of the aeroplane is circular. Reference has been directed by the Comptroller to Specification 133,134.
