Title: Improvements in or relating to Electrical Contact-breakers for Induction Coils and the like.
Inventor: BOWRON GEORGE
Filed: 1905-04-03
Granted: 1906-02-01
Abstract: 7019. Bowron, G. April 3. Switches.-In contact-breakers, especially for large induction coils, the rapidity and length of the break is increased by placing the movable contact-face on a separate pivoted spring-controlled lever, upon which the vibrating armature or armature lever, which has a limited play in relation to the contact-carrying lever, acts mechanically. The armature head may also be made of a tapering shape to cause an acceleration during its travel to the pole-piece, and may be laminated. In the form shown in Fig. 1, the armature C, mounted close to the attracting pole-piece B' upon a stiff spring C', has a rearward projection D passing through a lever E pivoted to a bracket G<1>. One end of the lever carries a platinum contact F opposite the fixed contact F<1>; the other end is attached to a setting-spring E' capable of being adjusted by a screw J. On the end of the projection D are screwed nuts D', the inner face of which comes in contact with the lever E shortly after the armature has commenced its inward motion. The amount of this clearance can be varied, and the best position for the pivot of the lever E can be determined by means of an experimental model in which the position can readily be changed. In a slightly modified form the lever E is horizontal. In another modification, shown in Fig. 3, the contact-carrying lever E is acted on successively at both ends, first by the nut face D<1> as before, and immediately afterwards by a tailpiece C<7> of the armature lever C<1> pivoted at C<6>, the object being to obtain greater power of separating the contacts. The lever E is in this form controlled by an adjustable spring K, or in any other suitable way. The armature head may be tapered, as in Figs. 4 and 5, or may be formed of a ribbon of iron or other magnetic material wound on a supporting-pin.

Title: Improvements in the Electric Controlling Arrangements and Circuits for Trains on the Multiple Unit System.
Filed: 1905-06-17
Granted: 1905-12-21
Abstract: 12,594. British Thomson-Houston Co., [General Electric Co.]. June 17. Distributing; lighting, systems of; switches.-Relates to train control on the multiple-unit system, and to the means provided for maintaining a continuous supply of current for control purposes, heating, lighting, &c. even though the supply be cut off from one of the cars, reference being made to Specification No. 818, A.D. 1904, in which electro-magnetic relays are provided. In the present arrangement, it is necessary to operate a switch when it is desired to obtain current from a following car on the failure of the supply to the first car. Figs. 1 and 3 show one arrangement, in which A ... A<3> represent the equipment of four cars, each having one or more mastercontrollers C, the control circuits not being shown. When circuit is being taken from the trolly T, it flows through the conductors 2, 3, switch 4, which must be thrown to connect with the terminal 5, switch 6, wire 7, and controller. When it is desired to take current from another car, the switch 8 on that car is thrown as shown at A<3>, and the switch 4 on the first car is thrown as shown, the current then being supplied through the train-wire. To break connexion with the trollys when the master-controller switch is thrown, the switches 6. 8 are interlocked as shown in Fig. 3, the hooked arms 13, 14 pivoted on the switch 6 engaging with a pin 16 on the switch 8. Figs. 2 and 4 show another arrangement, the current normally passing from the trolly T through the switch 17 to the controller C. The switch 17 is interlocked with the switch 18, so that both cannot be closed at the same time. The construction of one form of interlock is shown in Figs. 4 and 5. It consists of a sliding bar 19 having pins 20, 21 which engage with the switches 17, 18 and are at such a distance apart that only one switch 17 or 18 can be closed at one time. A second set of contacts 24, 25 is provided for connecting a trolly direct to the train-wire. A second interlock consisting of a sliding bar is provided for normally preventing both switches from being closed, but the switch 17 is fitted with a spring-pressed latch 30 which may be operated to allow the pin to pass so that both switches may be closed.

Title: Improvements in or relating to Electric Ignition Systems for Internal Combustion Engines.
Inventor: STURMEY JOHN JAMES HENRY
Filed: 1905-12-14
Granted: 1906-05-10
Abstract: 26,032. Sturmey, J. J. H., [Duryea, C. E.]. Dec. 14. Gas and like engines, igniting in. In the device' shown in Fig. 2, the movable terminal G is operated by the movement of a hinged armature E, a single but divided low-tension circuit serving to energize both the central core A and an induction coil for exciting the sparking- terminals. Surrounding. the removable central core A is a coil of wire, preferably insulated with a mixture of glass and powdered lava, and connected at one end to an insulated terminal C and at the other to an outer metallic casing B. Hinged to a second terminal D is an armature E which bears on a layer of insulation mounted above the core A. The terminal D also carries a spring F, which raises the armature, when the current in the coil surrounding the core is broken, and keeps the sparking-terminals in contact when the armature is lowered by the passage of a current through the coil. A small spring H ensures that the sparking-terminals are always in contact when the armature is in contact with the core. The lower sparking-terminal I is slightly eccentric to and of larger diameter than the movable terminal G. When the outer circuit is completed by the contact-breaker L, M, Fig. 6, current passes directly to the terminal C, through the coil and core, and back to the battery as shown. Upon the passage of current through the coil, the armature is drawn down by the core A and the sparking-terminals G, I are placed in contact by the spring F. This completes a second circuit through the wire R<2>, the spring F, sparking- terminal G, and the battery through the wire R. When the outer circuit is broken, the armature E is released and breaks the igniting-circuit by engaging with the collar G<1> and separating the terminals G, I.

Title: Improvements in and relating to Automatic Fluid Pressure Valves for Presses, Lifts and the like Machines.
Inventor: SMITH WILLIAM
Filed: 1906-01-26
Granted: 1906-12-13
Abstract: 2051. Smith, W. Jan. 26 Lifts.-An automatic valve for use with hydraulic lifts and similar machines is provided with a spring-loaded lift valve, which, as the pressure required in the machine increases, is set to open and admit high - pressure liquid through the medium of an intensifier. The Figure shows the construction of the valve arranged so as to be actuated by the pressure from an intensifier, which is adapted to rise as the work progresses and is so connected that it is only put into action when the low-pressure valve is opened. The lowpressure pipe 12 leads to the press, and a branch from it leads to the intensifier 14, the hollow piston of which forces liquid at higher pressure through the pipe 18 to the underside of the spring-loaded valve 20, which is thus lifted near the end of the pressing &c. operation to allow the high-pressure fluid to complete the work commenced by the low-pressure fluid.

Title: Improvements in and relating to Printing Machines.
Inventor: SOMMER WILHELM
Filed: 1906-02-10
Granted: 1906-07-05
Abstract: 3303. Sommer, W. Feb. 10. Printing in several colours. - Colour - printing machines for printing on webs are so arranged that each forme co-operates always with the same section of the circumference of the impression cylinder, the formes are inked several times before each impression, and the impressions are dried, by dusting, immediately after being printed so that the successive impressions may be made one on another. Fig. 1 shows a machine having an impression cylinder 1 and four printing-cylinders 2, 3, 4, 5, each having a diameter one-quarter that of the cylinder 1. The cylinders 2, 3, 4, 5 print the paper against the sections 6, 7, 8, 9 of the cylinder 1, respectively. The web 11 passes round the cylinder 1, and is fed with it while the printing-cylinders each make an impression, the web being then stopped and the cylinders 2, 3, 4, 5 lifted while the cylinder 1 makes the remaining three-quarters of its revolution. The cylinders 2 &c. are geared to the cylinder 1 so that they make three revolutions while lifted, without printing, and are inked during this time by their respective inking-mechanisms 12, 13, 14, 15. After each complete revolution of the cylinder 1, the web is again fed with the cylinder 1, the cylinders 2, 3, 4, 5 being lowered to printing contact, so that each section of the web is printed in four colours. The means for dusting the impressions comprise brashes 26 which are hollow and perforated to contain and distribute powder, such as magnesia, and brushes 27, 28 for removing surplus powder and brushing the impressions clean and dry. The brushes are enclosed in boxes, and surplus powder may be withdrawn by suction devices. Printing and impression cylinders 31, 30 may be provided for printing on the other side of the web, with powder brushes 32, 33, 34 acting against rollers 35, 36, 37. To prevent the brushes 26, 27, 28 from pressing the web against the cyllinder 1, and tending to feed it when it is stopped, they preferably act against stationary plates 29, between the web and the cylinder 1, carried by the machine framing. One or more reciprocating flat formes may be used to print against the cylinder 1 in addition to the forme cylinders, and the parts of the cylinder 1 against which they print may be raised to obviate movement of the flat formes to and from the cylinder 1.

Title: Improvements in Pneumatic Tube Systems
Inventor: BATCHELLER BIRNEY CLARK
Filed: 1906-04-21
Granted: 1906-12-06
Abstract: 9423. Batcheller, B. C. April 21. Pneumatic dispatch apparatus. -Provides for maintaining communication between the transit tube and the vacuum pipe or atmosphere, only for a predetermined time, after the insertion of a carrier. The timing-device consists of a piston P, Fig. 8, in a cylinder O which has a by-pass containing a needle valve and a lift valve, or, instead of the latter, the piston may carry an annular valve. As shown in Fig. 7, the mouth C of the outgoing pipe B is provided with a slide V<3> to be worked by a piston V<1> in a main cylinder V, the return pipe always being in communication with the vacuum chamber F through a pipe B<4> having no valve. The farther end of the cylinder V being connected by the pipe F<1> with the vacuum chamber F, the near end is connected by a pipe F<8> and branches M, M<1> to ports N, Fig. 8, at the stations, which are normally closed by lift valves Q on the piston-rods of the timing-devices. By opening one of the valves Q, atmospheric pressure is admitted to the cylinder V, to open the slide, and is maintained till the valve is closed again, after which continued suction through a bridge-pipe F<7> reduces the pressure in the cylinder till a spring V<4> overcomes it. As shown in Fig. 1<a>, a valve K is normally pressed on the top of the exhaust pipe B<4> by a spring K<3>, but is lifted off by atmospheric pressure on a diaphragm K<2> over a chamber E<5>, which hasan atmospheric port P<2> and an exhaustconnexion F<1>. Normally, a head on the stem of the timing device bridges two contacts on the cylinder, and a current is maintained through an electro-magnet P the armature P<1> of which constitutes a valve closing the atmospheric port. When the timing-device is operated, the current is suspended and the valve drops from the port to stop the exhaust-connexion F<1>. The stations are similar to those described in Specification No. 9224, A.D. 1902, and the hand-levers H<1> for opening the valves serve also to open the doors D<3> for insertion of the carriers.

Title: Improvements in Controllers for Electric Motors
Inventor: HART HARRY UTTER
Filed: 1906-05-29
Granted: 1906-12-13
Abstract: 12,492. Hart, H. U. June 12, 1905, [date applied for under Patents Act, 1901]. Switches.-A series-parallel electric-vehicle motorcontroller makes special reverse braking connexions by a continuation of the ordinary braking movement in the same direction without throwing over the reversing - switch. The circuits are changed from the condition indicated in Fig. 3 to that indicated in Fig. 4, in which the respective motor armatures 37, 39, the respective field windings 40, 38, a brake-magnet coil 34, a blow-out coil 36, and resistances 35 are shown. The continued building- up and braking effect depends upon one of the motors generating a higher voltage than the other, and thus reversing its field polarity. The mechanism of the main controller drum 1 and reversing- switch 31, Fig. 1, is identical with that described in Specification No. 1874, A.D. 1902, so far as the movements from the 'off' position shown to the ordinary power positions I ... IX and the ordinary braking positions A ... F are concerned, during which movements the roller 12 travelling in a cam-groove 8,. 9 acts through links 13, 15 upon the reversing- switch and sets it at the proper times. The additional feature of the present invention is a wave 11 at the end of the groove 9, which is reached by the roller 12 when the drum 1 is turned to the special braking position G, and then acts to shift the reversing-switch to an extra contact position, producing the above described change of connexions. Two such extra contact, positions are provided for the reversing-switch, one or other of which is used according to the way in which the reversing-switch was originally set. A diagram of the contacts and connexions is given in the Specification.
