Title: Improvements in and relating to Automatic Electric Switches.
Inventor: BOUTARD HJALMAR CHARLES ERNEST
IPC: H01H71/22
Filed: 1913-03-05
Granted: 1913-09-18
Abstract: 5546. Boutard, H. C. E. March 6, 1912, [Convention date]. Thermal switches, of the kind in which a circuit is made or broken by the expansion of air or gas heated in a chamber having a flexible diaphragm, are provided with a compensating- chamber also fitted with a flexible diaphragm arranged so as to counteract movements due to atmospheric changes. A heating-chamber a, Fig. 1, with a thin corrugated top b is fixed upon a box d and carries a frame f and a compensating - chamber g with a thin corrugated bottom. An electric resistance heater c is enclosed in the chamber a, and the chamber g carries a contact h normally resting on fixed contacts i, k. Current in the circuit m, n flows through the heater e and raises the contact h after a certain time. The device is shown as applied to energize an automatic switch winding p by breaking a short-circuit across its terminals k, after a time-interval. The Specification as open to inspection under Section 91 (3) (a) comprises also an automatic light - extinguishing switch, shown in Fig. 3 (Cancelled). The contact h normally in the circuit-open position is moved downwards to close the circuit by a hand push v and is there held by a spring z acting across arms x pivoted to a rod t attached to the contact h, the pivot passing from above the spring to below. The thin corrugated top b of the chamber a containing the heater c is also attached to the contact h and has a normally open valve r which prevents it from being affected by atmospheric pressure. The valve is closed by pushing-down the switch, and the heater then expands the enclosed air till the contact is again broken. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in Electrical Signalling.
Inventor: THOMSON JAMES CRUICKSHANK
IPC: B66B19/06
Filed: 1913-04-24
Granted: 1913-11-06
Abstract: 9632. Thomson, J. C. April 24. Mine signalling systems.-In colliery and other electric-bell signalling systems, a lamp or other visual indicator is operated at the same time as the bell. The lamp remains alight until extinguished by a separate operation, for instance by the movement of the engine starting- lever. Separate lamps are provided for the bells controlled from the top and bottom of the shaft. Successive rings on the same bell may light up several lamps in succession, as in the arrangement shown in Fig. 2. The incoming signal circuit terminates in a relay A controlling the bell B. At the first ring, a magnet C is energized in series with the bell B, and an armature D swings to the right and knocks round a star-wheel J, which operates contactsprings E, E'. The spring E closes the circuit of the lamp F. The circuit of the magnet C is opened at the spring E', but the magnet remains energized in a circuit through the contacts M, L controlled by the armature D. When the signal circuit is opened, the bell B stops ringing and the magnet C is de-energized and releases the armature D, but the springs E, E<1> remain depressed and the lamp F continues to glow. At the next ring, the magnet C is not affected, its circuit being open at the contacts E' and L, but a magnet C' is energized in a circuit through the contacts K, M, and the bottom contact of the spring E<1>, and a second lamp F<1> is lighted. A third ring may light a third lamp, and so on. The lamps are extinguished by a switch G, which energizes magnets H, H' to swing the armatures D to the left, so as to knock back the star-wheels J to their original position.

Granted: 1915-01-28
Abstract: 9958. Kohler, U., and Stocklin, C. April 23, 1913, [Convention date]. Periodic-counter speed indicators.-In apparatus wherein a measurement is taken at will by manipulating a spring stud 44 so as to effect the drive of the pointer for a period determined by an escapement, the engagement and disengagement of the parts are both effected by a cam-disk which is driven by the clockwork. On the pointer spindle 22 is mounted a sleeve 21, which is driven frictionally from the prime shaft through a gear wheel 17 and drives the pointer spindle also frictionally through a spring 25. Fixed to the sleeve is a disk 24 having a milled edge adapted to be engaged by a detent lever 35, the other end of which is in contact with a cam 36 fixed to a gear-wheel 38 and a snail-cam 39. A co-axially mounted e capementwheel 37, controlled by an anchor 45 and balance 46, is provided with a pawl 40 which may be engaged by the nose of the cam 39. The gearwheel 38 is in mesh with a toothed sector 41 normally rotated clockwise by a spring 43. To obtain a reading, the stud 44 is depressed to rotate the sector 41 against the action of the spring sufficiently far to enable the cam 39 to be operative against the p@wl 40. On releasing the stud, the escapement mechanism works, and the cam 36 moves the lever 35 and so releases the wheel 24 and the pointer. The po'nter travels for a space of three seconds, at the end of which time the wheel 24 is again held and the pointer remains stationary. The pointer spindle 22 carries a gearwheel 29 which actuates a train of gearing terminating in a second pointer for showing the number of revolutions of the first pointer. The pointers are zeroized by turning an external button fixed to the pointer spindle. The drive to the wheel 17 from the spindle 4 is effected through a one-way driving-mechanism consisting of gearing 3, 5, 6, 9, 10, 11, 12. The pinions 9, 10 are mounted on a lever 7 connected frictionally to the shaft 5<1> of the gear-wheel 5, so that this lever rocks in accordance with the direction of rotation of the prime shaft, and the drive is conveyed to wheel 11 or 12. In order that the instrument may be applied to shafts differing widely in speeds, alternative trains of gearing are provided for transmitting the drive from the wheels 11, 12 to the wheel 17. These trains are arranged on a lever 13 which can be adjusted by an arm 19 to throw either train into action. In place of the pawl lever 35 controlling the pointer mechanism, the connexion and disconnexion may be effected through a clutch or by disengageable gear-wheels.
