Patent GB-190717410-A (GB)
Title: Improvement in Electric Switches.
Filed: 1907-07-30
Granted: 1908-02-06
Abstract: 17,410. Siemens-Schuckertwerke Ges. Sept. 24, 1906, [date applied for under Patents Act, 1901]. Switches.-A rotary switch has the handle g rigidly fixed to the operating-spindle a, which is provided with a fixed pin t for engaging ratchet teeth z on a loose collar m, so that the spindle only operates the switch in one direction. The collar has inclined projections v, which engage corresponding inclined recesses on the switch body k, and lift the latter out of engagement with a crown-wheel clutch h, so as to bring the movable contacts b carried by the body k into contact with fixed contacts c. A quick make-and-break is given by 'an axial spring f on the spindle which connects the loose collar m and the switch body k. To prevent the collar m from sliding on the spindle when acting as a "lifter," the ratchet teeth z may be undercut.
Patent GB-190721173-A (GB)
Title: Improvements in or relating to Automatic Switches for use in Electric Circuits.
Filed: 1907-09-24
Granted: 1908-03-12
Abstract: 21,173. Siemens Bros. Dynamo Works, [Siemens-Schuckertwerke Ges.]. Sept. 24. Cut-outs; switches.-A thermal cut-out of the hot-wire type is adapted to close the circuit of an electro-magnetic relay which, after interrupting the working circuit, keeps it open until the hot wire has shortened to a definite extent, so that an interval may elapse before the main circuit is closed again. A comparatively short hot wire is used. As shown in Fig. 1, the current normally passes from a line +, hot wire h, switch arm s, and contacts c to the load v. The hot wire h supports switch arms s<1>, s<2> in insulating stirrups i. When the hot wire sags on overload, the switch arm s<1> makes contact at c<1>, and after a definite interval, if the overload persists, the switch arm s<2> makes contact at c' and so closes a circuit from the line +, through the switch arm s<2>, contacts c<2>, c', switch arm s', and through a relay e. The relay attracts ts armature s<3> and opens the working circuit at contacts c, the switch arm s making contact at c<3> and so closing a circuit from the line +, hot wire h, switch arm s (dotted position), contacts c<3>, c<1>, switch arm s<1>, and through the relay e. When the hot wire shortens through cooling, contact is broken at c<2>, but the relay circuit is still closed through the contact c<1>. After a definite interval depending upon the difference in height between the contacts c', c<2>, the circuit of the relay is broken at c', and the main circuit is again closed by the action of a spring s<4>. In the arrangement shown in Fig. 2, when the hot wire h sags, contact is made at c<2>, and the relay e is energized and attracts its armature and so breaks the main circuit at c. The switch is held in the open position by a crank lever w, which is drawn by a spring f against a stop a, and the vertical arm of which engages the tail of the lever s at the point w<1>. When the hot wire commences to shorten, the electro-magnet e is de-energized, and the hot wire begins to trip the crank lever w by means of a bolt b; after a certain time, the engagement of the crank lever at w<1> is released, so that the switch lever s closes and the circuit of the lamps or the like is remade. Instead of making the hot wire act directly as a conveyer of current, it may be heated by means of a heating-device through which the working current flows.

Title: Improvements in Apparatus for Indicating the Position of, for Communicating with, and for Salving Sunken Ships and other Objects.
Inventor: BERTRAND JOSEPH
Filed: 1907-12-10
Granted: 1908-12-10
Abstract: 27,237. Bertrand, J. Dec. 10. Sunken ships &c., raising; buoys.-Buoys 6 for indicating the position of sunken ships are held in position on caissons 2, Fig. 4, placed on the deck of the vessel, by maintaining a vacuum therein, and are released by breaking the vacuum either by hand or automatically. Near the lower end of the pipe 10 carried by the buoy is a hook 15, which is connected to the vessel by such a length of cable that it takes up a vertical position when the buoy floats to the surface, and therefore readily engages the ring on the end of the lifting-chain when it is slid down the pipe 10. The buoy is preferably made of cork surrounded by a metal casing 6, and the pipe 10 may be connected, for the whole of its length, to electric conductors, which are carried, when in the caisson, by pivoted brackets 12. The various caissons may be connected together by conduits 23 in which a vacuum is normally maintained. Fig. 6 shows one form of valve for breaking the vacuum. The valve is automatically operated when the submarine, for example, sinks below a certain depth ; the pressure on the outside of the piston 27 forces it back against the action of an adjustable spring 28 and uncovers ports 26, thus allowing water to enter the conduits 23 and caissons 2 and force the buoys off their seats. Branch conduits may be carried into the watertight compartments of the vessel and may be similarly provided with valves. The pressure may be augmented by the disengagement of any gas, for example compressed air or acetylene. The invention may be applied to torpedoes.
