Patent GB-190320907-A (GB)
Title: Improvements in Telegraph Systems.
Inventor: JONES CHARLES KINNEY
Filed: 1903-09-29
Granted: 1904-06-09
Abstract: 20,907. Jones, C. K. Sept. 29. Signalling-instruments; signalling to cabins and stations.-Relates to telegraph systems, more particularly for use in connection with the working of railways. Fig. 1 shows in diagrammatic form the apparatus at one of the stations on the line 1, 2. The operator's key 8 is normally closed, and the line circuit is completed through the wires 10, 11 and relay 7. A current normally flows in the line, the relay 7 being energized and the wires 12, 14<a> bridged by the relay contact at 12<a>. In these circumstances, the battery 13 sends current through the sounder 6, and the battery 13<a> energizes the electromagnet 17 through a circuit comprising a contact 23, wire 25, contact 12<a>, wires 34, 32, and contact 28. The operator can earth either of the sections 1, 2 by placing the plug 36 in one of the holes in the plug switch 4. in which case the earth circuit comprises the cord 35, wire 32, contact 28, wire 55, contacts 56, 58, and earth. In that case, the circuit of the magnet 17 is broken at 23 and the magnet de-energized. The same thing occurs if the key 8, after use, is left open, for the contact 12<a> is then left broken, and the batteries 13, 13<a> oppose one another in a circuit including both the sounder 6 and the electromagnet 17. Provision is made for restoring the through line circuit after a definite time interval in both these cases, thus removing an earth or break inadvertently left by the operator. For this purpose, the armature 16 of the electromagnet 17 is provided with a pivoted shoe 19 which, when the magnet 17 is de-energized, comes into contact with a roughened disc 18 slowly rotated by clockwork. After the expiration of, say, two minutes, the shoe 19 has been carried round sufficiently far to cause the end of the armature 16 to tilt the lever 30 and make contact at 29, 30. This completes the circuit of a battery 45 through a bell 40 and through an electromagnet 38 in shunt with it, the armature 16 being then positively held down until it is mechanically restored by the operator. Contact beiug made at 49, 50, the key 8 is bridged across by the wires 54, 53, armature 16, contacts 49, 50, and wire 51, the line-wire being thus closed. Any earth connection is at the same time removed by the break at 28. If the line-wire is broken either by accident or with the intention of calling up operators out of earshot of their sounders or to call the attention of all the operators to one common message, the bells 40 are also set in action.

Title: Improvements in and relating to Gas Driven Turbine Motors
Inventor: WILSON LIDA
Filed: 1903-11-03
Granted: 1904-08-25
Abstract: 23,872. Wilson, L. Nov. 3. Gas turbines.-A turbine driven by a combustible liquid or gas is shown in Figs. 2 and 4. A pump driven by the turbine draws the combustible fluid through a dust collector, and a second pump compresses air, and the two pass through check valves G, G<1> respectively to sectional combustion chambers F, being heated in the peripheral channels F<1>. The charge is exploded by an igniter, or by the heated walls of the chambers, and passes through nozzles H to the turbine blades, the form shown being of the usual parallel-flow type. The nozzles are fitted with rotary plug valves K, Fig. 5, which receive an oscillatory motion from frictional surfaces on a ring L, or a rotary motion from a geared ring L<1>, the rings being rotated by coned-pulley gearing or other variable-speed gear. The valves have water channels with perforations k opening into the nozzles to cool the charge. The combustion chamber is cooled by means of a water jacket J and, by having the air supply at a greater pressure than the gas supply, or the admission valves suitably arranged, the air supply is admitted both before and after the gas is supplied to the chamber. Condensation water may be removed by means of trough devices of the kind described in Specification No. 12,184, A.D. 1903.

Granted: 1904-09-08
Abstract: 25,744. Harris, A. Nov. 25. Water - tube boilers for motor cars, yachts, &c. are built up of a number of independent elements, any one of which can be readily removed and replaced by a new one. Each element is composed of six tubes a, Fig. 2, of comparatively small diameter and expanded at the ends into boxes b. The several elements are arranged in horizontal rows, Fig. 1, the boxes b being fitted into apertures in the end casings d. Bends c connect the elements of each row in series. The tubes a, instead of being circular in section, may be flattened out or formed rectangular in shape with rounded edges ; or they may be made mainly rectangular with semicircular top and bottom sides. In all cases, however, the tube-ends are circular. According to the Provisional Specification, the two top rows of elements may be used as superheaters.
Patent GB-190327046-A (GB)
Title: Improved Street-car Fender.
Inventor: HIRSCH ROBERT
Filed: 1903-12-10
Granted: 1904-06-02
Abstract: 27,046. Hirsch, R. Dec. 10. Obstruction-removers -In a fender for street cars, two rollers or brushes normally extending across the track, on engaging an obstruction, are set in rotation from the axle, and, at the same time, are swung round on a pin at one end so as to throw the obstruction to one side. When the front roller meets an obstruction, centrally-pivoted bars o, o<1>, in which the rollers are mounted, are thrown out of the horizontal position, and, by drawing on one of the cords or chains p<2>, a cranked lever p is caused to force in a spring v and a guide u, thus releasing an arm of a lever i from a nose w of the guide. A sliding clutch q, formerly retained by the lever i which is pivoted to the frame e, is thus released to be forced by its spring into engagement with a loose pulley h driven from the axle, so that the shaft g, bevel gear k, l, sprocket-wheels m, m', m<3>, and the rollers are set in rotation. At the same time, a disc r, Fig. 7, having three teeth engaging a tooth y on the wheel k, is rotated, so that a pin s under the influence of its spring is depressed into a gap r', thus releasing a flange of a pin c<1>, which, together with a pin c, extends through slots f<1>, f, respectively. The frame e is thus freed to be swung by a opting t as far as allowed by the slots, when the rotating-rollers are thus brought substantially parallel to the track. As the fronts of the rollers move upwardly, there is a tendency to lift the body from the ground. To re-set the apparatus, the free end of the frame is pushed below the car, and the disc r is returned by pulling a rod s<2> until the conical point of the pin s is lifted by the disc, whereupon the pin snaps into place and again retains the frame. The lever i must now be depressed and the rollers set horizontal, when the nose w again retains the lever.

Title: Improved Method of Making Printing Surfaces.
Inventor: WHIPPEY FREDERICK COFFIN
Filed: 1904-04-05
Granted: 1904-06-02
Abstract: 7887. Whippey, F. C. April 5. Photo-mechanical, printing; enlarging.-Printing- surfaces obtained by reproducing drawings, photographs, or the like by means of photography are made on a larger scale than hitherto, the surface obtained being used directly for printing, or being transferred to a lithographic stone. The process may be applied to three-colour printing. The picture is photographed through a grained, stippled, or lined screen which need not be used in the case of a pen-and-ink drawing. The negative is developed and enlarged upon a plate of copper, zinc, aluminum, stone, &c. coated with sensitized emulsion. The apparatus used is shown in the Figure. Light from the sun or from an electric arc 1 is passed through condensing-lenses 2 and through the negative 3, and an image is projected by the camera lens 5 upon the sensitized plate. After exposure, the entire surface of the plate is coated with ink ; the plate is developed or washed and etched with acid. The emulsion is then washed off and the plate used for printing ; or the emulsion may be left on the plate and used as the printing-surface. An enamel emulsion may be used, the ink coating being dispensed with. To use the design for lithographic printing, the plate is inked and washed, and the unexposed surface is coated with gum arabic and water, after which the ink on the exposed surfaces is washed off by means of turpentine or the like. The entire surface is then coated with lithographic ink and the plate washed with water, which removes the ink from the unexposed parts. The design is then transferred to the stone by means of transfer paper.

Patent GB-190500861-A (GB)
Title: Improvements in or relating to Apparatus for Automatically Receiving, Delivering and Exchanging Tablets, Staffs, or the like on Railways.
Inventor: WHITAKER ALFRED
Filed: 1905-01-16
Granted: 1905-12-07
Abstract: 861. Whitaker, A. Jan. 16. Transferring articles to or from trains in motion. -Apparatus for exchanging staffs or tablets while trains are in motion consists of a combined receiver and holder mounted on a vertically and laterally sliding bar on the engine and separate receiver and holder mounted on two arms on a rotating post which are automatically returned to a position parallel to the track after the tablets are received or delivered or exchanged. The tablets or staffs are carried in a pouch provided with a metal ring. The tablet holding and receiving apparatus, Fig. 7, consists of a casting b with two jaws c, d with a flared opening between them provided with two or more spring-operated catches e, e', to prevent the tablet-carrying ring from falling out after it is caught. Blocks of india-rubber c<4>, g serve as buffers to prevent injury to the tablet. The tablet to be set down is held on the projection b<4> by the arms b<2> which are mounted on lateral projections and are pressed inwards by springs so as to hold the tablet vertically. Modifications are made for holding and receiving a staff, consisting chiefly of the provision of a pair of spring jaws at a suitable distance below the casting b to receive the staff itself. These jaws are also fitted with a rubber buffer. The complete apparatus is shown in Fig. 2. A combined receiver and holder, Fig. 2, is mounted on a bar i by a bolt through the hole b<5>. The bar i slides in a fixed guide j and is held in its two end positions by a spring pin. To ensure that the height of the bar i above the rails is not altered by the variable loading of engine or tender, a set of compensating-levers are inserted between the axle-box and the guide j, which is then made movable vertically. A receiver p is fitted to the upper, and a holder q to the lower, of two arms n, o of a post l which is rotatable in the pillar m, and is held in position at right-angles or parallel to the track by a detent r entering a rounded notch in the collar m'. To exchange tablets, the arms n, o are swung out and the arm i is pushed out so that the tablet-rings a' may enter their respective receivers and the tablets be oxchanged. The blow so caused is sufficient to disengage the detent r from the collar m<1>, and the weight u then descends and completes the movement of the arms n, o. At the ends of a section of single line, a receiver or holder alone is mounted on a post. In order automatically to replace the holder when the tablet is removed, it is attached to a counterweighted lever o<1>, Fig. 5, which is pivoted on a pin o<2> to the arm o, and the other end of which serves as detent in the collar m<1>, and falls away when the tablet is removed. In place of the weight on a wire, bevel-wheels with a weighted crank may be used so that, when the detent is removed, the crank is revolved and moves the arms to the inoperative position.

Title: Improvements in Voting Machines
Inventor: JACKSON CHARLES STEWART
Filed: 1905-07-20
Granted: 1906-07-19
Abstract: 14,976. Jackson, C. S. July 20. Voting - apparatus.- A machine of combined pull-bar and ball type is arranged for rejection of irregular and excess voting balls by the presiding officer, who releases the voting-bars for normal operation, these bars being interlocked when the voter opens a bar shutter, and locked after one stroke until the officer resets the apparatus. Each bar opens the proper shoot-for the ball, prevents insertion of a second, operates the total counter, and also the candidate's counter as it becomes locked. Adjustable means are provided for limiting the total operation of the machine by a single voter. Figs. 1 and 4 show in front view and section a machine for candidates run by two parties for each of two offices. A ball placed by the voter in the shoot 18 is inspected by the presiding officer through the window 22, and, if irregular, the bridge 20 is operated to send the ball by a shoot 24 to the pocket 26. Otherwise, the following movements precede operation of the bridge. The release handle 27 is pulled out to sound the bell 38 and withdraw the locking-bars 32 from the recesses of all voting-bars 34, whereupon the voter lifts the indicator shutter 39 of the chosen bar in order to lock all other bars by means of selecting link-work and locking-bars 47, 46, 45, 44, engaging the stops 49, and withdraws the bar until spring arms 51 snap the cross-piece 50 into the locking-recess and hold the bar, at the same time registering by suitable link-work on the candidate's counter 75. The downward arm 56 of each bar opens a trap 52 over the appropriate ballot box 17, of which there are four, and the upward arm 57 has attachments for operating the totalizing-counter 80, ringing the bell, oscillating the cross-har and arms 64, 67 to prevent insertion of a second ball for that bar, and regulating the number of bars operated by one voter. For this purpose, a ratchet-wheel on the spindle 85 is moved by a pawl until the adjustable pin 92<a>, Fig. 17, contacts with one of two stops 91 which limit the motion, whereupon the presiding officer depresses the bar 93 to lift a detent and allow the ratchet-spindle to fly back to initial position under the influence of a spring. The resetting-handle 69 lifts all the cross-pieces 50 and allows the springs 74 to restore the bars.
