Title: Improvements in Steam Engines.
Inventor: BEARDMORE CHARLES EDWARD
Filed: 1902-06-25
Granted: 1902-12-04
Abstract: 14,382. Beardmore, C. E. June 25. Slidevalves valve chests and casings cylinders; cylinders, draining; compound and multiple-expansion engines.-The objects are to reduce clearance while securing large port area, to obtain a practically-balanced slide valve, to improve the drainage of the cylinders, and to obtain a direct flow of steam while simplifying the cylinder castings. Fig. 1 shows the invention embodied in a twocylinder vertical compound engine, and Fig. 3 shows a horizontal section through the cylinders, valve, and valve-chest. Both the cylinders H, L are served by a single valve V working between two port faces, one for the high-pressure cylinder H and the other for the low-pressure cylinder L, shaped as shown in Fig. 3, and so proportioned as regards area as to obtain a practical balance of pressures. The cranks are arranged opposite each other, and the valve is worked by a single eccentric G at the middle. On the high-pressure side, the valve V receives live steam at the centre in the cavity S<1>, and exhausts through the end ports h, h', while, on the low-pressure side, the steam is supplied by the end ports, which communicate directly with the ports h, h<1>, and is exhausted directly into the valve chamber E by ports nearer the centre. In order to permit the use of short straight ports, and to allow of the proper relative proportioning of the valve faces, the exhaust chamber E is made longer than the cylinders. At the same time drainage is promoted, the exhaust pipe E<1> being connected at the lowest point. Surmounting the valve-chest is an air-cushioning cylinder K, in which works a piston k mounted on a prolongation of the valve spindle. The cylinder covers may be secured by shore studs F or otherwise. In one modification, the invention is shown embodied in a two-cylinder simple engine, the valve being slightly modified to adapt it to this working, and, in another, it is shown embodied in a three-cylinder triple-expansion engine with two valves between the three cylinders.

Title: Improvements in Appliances for Intercommunication of Telephones.
Inventor: ANDERS GEORGE LEE
Filed: 1903-01-22
Granted: 1904-01-22
Abstract: 1561. Anders, G. L., and Smith, R. T. Jan. 22. Telephone systems.- Relates to intercommunication telephone systems. The receiver normally hangs on the hook B, Fig. 6, and holds the lever arm I in contact with a plate H, Fig. 2, depending from a bar C pivoted at E<1>, E<2>. A coiled spring D acts on the bar C both by compression and by torsion, the latter tending to break the contact between the plate H and the call-bell contact V, which is maintained by the action of the arm I. When one of the plungers Q is depressed to ring up another station, the bevelled and notched end R of the plunger forces the bar C aside against the compression of the spring D, thus releasing any other plunger that may be depressed. Each plunger is connected with one of the line-wires, and the lateral movement of the plate H causes contact to be broken at V and made at N, thus putting a call battery to line. On the release of the plunger, the bar C returns sufficiently to remake contact at V. When the receiver is removed from the hook. the torsion of the spring D rocks the bar C sufficiently to break contact at V and make contact between the plate H and telephone contact S. The return of the receiver to the hooks lifts the lever arm I and moves the plate H and bar C laterally sufficiently to release the depressed plunger or plungers. In a modification, the plungers are arranged in a circle, a toothed or star wheel taking the place of the notched bar C. A pivoted cradle lever replaces the receiver hook. The call bell or the transmitter may be placed in the centre of the ring of plungers.

Title: Improvements in Oil Lamps
Inventor: BRUNO-AUSTIN FREDERICK JAMES D
Filed: 1903-03-05
Granted: 1903-07-30
Abstract: 5210. Austin, F. J. de Bruno-. March 5. Extinguishing oi l lamps.-Relates to an arrangement for extinguishing lamps in case of overturning. In lamps with a circular wick and central draught, a rod A, which may be weighted at its lower end, passes through guides L, L<1>, in the central passage B. At the top of the rod is a flame spreader C, consisting of a concave plate G, with a central hole in which is inserted a perforated plate H and a perforated tube J which works in the end of the wick-tube E. The rod A is screwed at the end where it passes through the plate H, the position of the spreader being adjusted by nuts D, D' on the rod. When the lamp is standing on a table, the lower end of the rod rests on the table and holds the spreader well above the wick. A metal rim F surrounds the top of the wick-tube, so that, when the lamp is overturned, tilted, or lifted, the spreader falls on to the rim and is then just clear of the wick, the flame being thus extinguished. A stop K on the rod projects through a slot in the lamp body, and is held by the hand when the lamp is to be moved without being extinguished. In lamps other than those having a central draught, the rod slides through suitably-arranged tubes.

Title: Car Couplers.
Inventor: ALLISON CHARLES ARTHUR
Filed: 1903-06-02
Granted: 1904-02-25
Abstract: 12,471. Allison, C. A., [Barnard, C. A.]. June 2. Couplings, automatic.-An automatic coupling for cars is locked against uncoupling while under strain, and the coupling-hook is locked in its uncoupled position, but automatically released upon coupling impact. The coupling comprises a head A with a coupling-hook B and an unlocking-shaft D operated by a rod E extending to the side of the Vehicle. The buffer head is pivoted to the draw-bar and has sockets to receive the springs b engaging the hook, the pivot hole b<2> of which is elongated. When the hooks are in coupling position, Fig. 3, the point b<5> of the incoming hook strikes the corresponding point of the stationary coupler, and one or both hooks are forced to swing outwardly against the resistance of the springs. As soon as the points pass each other, the hooks are forced back into engagement by the springs b and coupling is effected. On the application of the draught strain, both hooks move longitudinally until the shoulders b<3> engage ledges a<2> on the head, when the hooks are locked against uncoupling. When the pull is relaxed, the springs b force the hooks into their original position, disengaging the shoulders b<3> and leaving the hooks free for uncoupling. The hook is swung back for uncoupling, by means of a cam d on the shaft D, Fig. 8, adapted to engage the inner edge of the hook. During the uncoupling rotation of the shaft D, the projection d<2> travels up the inclined face of a stop on the head, and the tension of the springs drawing the projection behind the stop locks the hook in its uncoupled position. If coupling be now attempted, the point b<5> of the hook will be struck by the point of the incoming hook, and the hook, thrown slightly outwards, moves an engaging-shoulder of the shaft correspondingly, so that the projection d<2> is dislodged. The cam d lies in the path of the edge of the hook, but, owing to the weight of the handle of the rod E, and to the engagement of the inwardly-moving hook with the cam, the shaft D is rotated, and coupling is effected, as before. In uncoupling, the points of the hooks similarly engage, and, dislodging the projection d<2>, cause the return of the hook to the coupling-position.

Granted: 1904-08-27
Abstract: 18,581. Leitner, H., and Lucas, R. N. Aug. 28. Dynamos, regulating.-Relates to the system of train lighting described in Specification No. 23,066, A.D. 1902, in which a differentially-wound main generator is combined with a subsidiary or controlling compound-wound dynamo. An additional electromagnetically-controlled switch or contact is provided for preventing the excitation of the subsidiary dynamo until the main dynamo has excited. In the Figure, e, f represent the armatures of the generators, and a, c and b, d the respective fields. The controlling-switch, shown as a mercury switch, is fitted with the three contacts 1, 2, 3. It is operated by a motor having an armature winding l and field windings j, k. When the controlling-switch is in the 'off' position, as shown, the contact x short-circuits the resistance from the circuit of the shunt field winding a of the main generator, and so facilitate excitation. On the first movement of the switch, the contact x is lifted and the contacts 1 and 2 dip in the mercury, and connect up the main generator. Subsequently, the contact 3 dips into the mercury and connects up the fine winding b of the subsidiary motor across the battery g. This arrangement may be applied to other systems than that described in the above-mentioned Specification.

Abstract: 8516. Stearns, R. B., and Ward, F. D. April 18, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Couplings, automatic.-An automatic coupling, which is particularly useful on elevated railways, is shown in plan and side elevation respectively in Figs. 1 and 2. The draw-head on each vehicle has buffer faces 2, 3, between which is a cavity 4 extending entirely through the head. A pin 6 can rotate upon an inwardly-extending flange at tha lower end of a semicylindrical recess in one wall of the cavity 4, and has a projection 16 adapted to be engaged by a spring 18. On two vehicles meeting, a hook 14 on a bar bolted between the two webs 9 of the draw-bar of each vehicle engages a notch 17 extending through the pin 6 on the adjacent vehicle, and rotates the pin against the action of the spring 18. When the hooks have passed the pins, the latter are returned, by the springs, to their normal positions, in which the cylindrical portions of their peripheries engage the hooks, Fig. 1. To uncouple, the pins are rotated by means of arms 15, which have rods 20 pivoted to them to permit of their being operated from outside the rails. As the coupling is disconnected on one vehicle moving vertically relatively to the other to a sufficient extent, it prevents a vehicle which may be de-railed from pulling the other vehicles of a train after it.

Granted: 1905-04-13
Abstract: 8755. Lees & Co., A., and Taylor, R. April 16. Driving-arrangements for spinning and doubling frames. The tin-roller shaft is provided with twospeed driving-mechanism, the lower speed being employed during the formation of the cop-bottom, when the higher speed is brought into action either by hand or automatically. The tin-roller shaft a carries three belt pulleys d, c, b, of which d is fast to the shaft and drives it at the fast speed, and c is carried by a loose boss on the shaft, the boss carrying also a rope pulley e, which drives by means of a rope a larger pulley f either fixed or clutched to the shaft, while b is a loose pulley. Spur gearing may be used in place of the rope gearing shown. The starting-handle i is weighted, and is held in the position shown against the action of its weight h or a spring by a catch k, the strap being on the loose pulley b. When the strap is on the slow-speed pulley c, the starting-handle is held in the required position by a catch k<2>, which is automatically released at the required time to allow the weight h &c. to move the strap on to the high-speed pulley d. The catch k' is connected to a swinging lever p, which, during the formation of the cop-bottom, is held in the inclined position out of the path of the copping-lever s by reason of a stud m on the ring rail holding in the raised position a weighted catch-lever n. When the rail has been raised to a sufficient height, the lever n falls and releases the lever p, which is raised by the copping-lever so as to liberate the catch k'. The levers n, p are adjustable so that the moment at which the change of speed is effected may be regulated.
