Patent GB-190312741-A (GB)
Title: Improvements applicable in connection with Steering and like Engines
Inventor: ALLEY KENNETH MATHIESON
Filed: 1903-06-06
Granted: 1904-06-02
Abstract: 12,741. Alley, K. M. June 6. Steering-gear.-Two hollow piston controlling-valves are used instead of a single controlling-valve, waste of steam in the steam passages at each reversal of the engine being thus minimized. The Figure shows a sectional side elevation of parts of the gear. The valves A, B work in liners carried in casings formed integral with the distribution valve casings C and cylinders D, E, and each casing has one inlet port A' and one exhaust port B', communicating with the steam-supply pipe F and the exhaust G. Valves C', D<1> and C', D' are placed between the controlling and distributing valves. The spindles A<2>, B<2> of the controlling- valves A, B are moved synchronously in the same direction by suitable means. The annular spaces F are open to the steam supply, and the interiors of the valves are open to the exhaust. If the valves A, B be moved downwards, the port C', is uncovered to the annular space F of the valve A, 'and the port C<2> to the annular space F of the valve B, and live steam will thus gain access to the annular space G', surrounding the central part of each distributing-valve C (only one of which is shown) and find its way to the cylinders D, E, through ports H ; at the same time, the port D<1> is open to the inside of the controlling-valve A, and the port D<2> to the valve B, so that the insides of the two distribution valves 0 are open to the exhaust G, by way of the ports B<1>. When the controlling - valves are moved upwards, the action is reversed. This arrangement may be applied to any number of cylinders, each having its controlling-valve.

Title: Improvements in and relating to Electric Burglar Alarms for Vaults, Safes and the like
Inventor: MILLER CHARLES OSWALD
Filed: 1903-06-08
Granted: 1903-07-23
Abstract: 12,865. Miller, C. O. June 8. Alarms, burglar and like.-Vaults, safes, and the like are provided with a casing containing air under pressure, the escape of which sounds a gong alarm electrically. Fig. 2 shows a section through part of a vault 2, the air casing being formed between steel plates 20, 21 in sections which are connected by tubes, a flexible tube being used to connect the air casing of the door 3 with that of the vestibule. If the air pressure falls, because of perforation of the vault, the falling of a pointer on a connected pressure-gauge closes a gong-alarm circuit, and so sounds the alarm. The door 3, Fig. 8, may be bolted by vertical and horizontal bolts 4, 5, simultaneously actuated by a swivel 6 and bell-crank levers 7, and fixed in place by the bolt 9 of a combination or the like lock 8. The bolts 4, 9 carry insulated contacts 12, 11, which connect with contacts 15, arranged on the side of the door, so as to make contact with similar contacts 16 on the door frame, Fig. 2, when the door closes. These contacts 16 lead to the gong alarm, and the locking and unlocking, or closing and opening, of the door are thus utilized in the signal circuit. Fig. 6 shows the gong alarm 27, which is fixed outside the vault, and is protected by an aircased shield 28, which communicates by means of tubes 29, 30, 31 with the vault casing. To prevent the prying-off of the shield without detection, tubes 33 are fixed to the shield, and are surrounded by tubes 32 fixed to the vault casing. A flange 34 on such tube 33, Fig. 7, bears, by means of a coiled spring 36, on a flange 35 on the tube 32, which also carries a projection 38, arranged, on an attempt being made to remove the shield by prying, to press in a rod 39, and so open a valve 40, thus releasing the air in the tube 41, which is connected to the vault casing. and so sounding the alarm. Arms 43 on the rod 39 are arranged to engage with shoulders 44 in the tube 43, so as to allow the air to escape easily by keeping the valve open. A baffle-plate 45, Fig. 6, prevents the insertion between the shield and the vault wall, of any instrument for muffling the gong. The electric alarm circuits comprise local and distant circuits, both being so arranged that the alarm is sounded by any burglarious attempt. It is also possible for an official at his house on the distant circuit, to ascertain whether the vault door is closed or open.

Title: Improvements in Air Brakes.
Inventor: WESTINGHOUSE GEORGE
Filed: 1904-05-31
Granted: 1904-07-14
Abstract: 12,374. Westinghouse, G. June 2, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Brakes.-Relates to air-brake systems for trains having two or more cars provided with a complete brake equipment, the brakes being applied by a reduction of pressure in the train-pipe. Means are provided whereby air may be supplied to the train-pipe from all the main reservoirs, while dispensing with additional main-reservoir pipe couplings between the cars. A release valve in a casing 9 is inserted between each main-reservoir pipe 2 and the train-pipe 3, the valves being simultaneously operated by electric means which are controlled by the movement of the handle of one of the motormen's valves 6, the other valves 6 being set in "lap" position. When it is desired to release the brakes, one of the valves 6 is turned into "release" position, whereby a bar 22 attached to the brake-valve handle completes a circuit through electromagnets 23, each thereby closing a valve 25, Fig. 3, and opening a valve 24. Air from the main-reservoir pipe 2 now passes through the pipe 16, valve 24, and pipe 14, and depresses a piston 11, Fig. 2, which opens the release valve 10 to effect communication between the main-reservoir pipe 2 and the train-pipe 3 by the pipes 12, 13. On opening the circuit, the valve 24 closes, and the valve 25 opens to allow the air to escape from behind the piston 11 and so to close the release valve. A pressure-reducing valve 32, set at normal train-pipe pressure, prevents an overcharge of the train-pipe. The magnet circuit may be opened and closed by a separate switch.

Title: An Improved System and Apparatus for Electrically Operating Bulkhead Doors, Hatches or the like.
Inventor: JONES ALLEN PARRY
Filed: 1904-06-20
Granted: 1905-02-09
Abstract: 13,927. Jones, A. P., [" Long Arm " System Co.]. June 20. Bulkhead doors; hatches.-Relates to apparatus for operating sliding bulkhead doors, hatches, or the like, either by hand or electrically, and includes means for automatically cutting-off the current when the load on the motor becomes excessive, and for signalling when the door is in a n y predetermined position. Reference is made to Specifications No. 13,026, A.D. 1899, No. 16,748, A.D. 1901, and No. 22,341, A.D. 1902. The sliding door B, Figs. 1 and 3, is operated through its curved worm-rack B<1> by an electric motor C, which carries on its armature shaft a pinion C', which drives the gearwheel E, splined on the sleeve F, through the idler D on the shaft D<1>. The sleeve F terminates at its lower end in a worm F', preferably hollow, and on the inside of which is secured a sleeve F<2> carrying roller bearings f. The sleeve F<2> is loose on the fixed shaft G secured at its lower end to the bridge K, which spans the door frame, and at its upper end to the casing K secured in turn to the casing fast to the door frame. The shaft G is shouldered at g, g<1>, g', hollowed for the purposes of lubrication, and carries the loose collars R, H<1>, between which is held under compression a stout coil spring I, the initial compression of which is regulated by means of the nuts G<1>, G<2>. The sleeve is provided with a thickened head F<3>, which is shouldered at f<3>to provide a bearing for the upper antifriction bearing f<1>, and has an annular groove f<4> to receive the yoke L pivoted to the arm M. The head M<1> of the arm M, pivoted by means of the pin m to the casing K<1>, has inclined faces m<1>, Fig. 6, and a central operating-lug m' normally lifting midway between the lugs n, n' of the yoke N secured to the rock-shaft N' and connected to a cut-out or limit switch. When the movement of the door is resisted by any obstacle, the sleeve F is pushed against the spring until the yoke L swings the arm M on its pivot, which rocks the yoke N and causes the limit switch to be thrown out of contact, shutting off the motor. When the pressure on the door has been relieved, the spring I automatically returns the parts to their initial position. To close all the doors simultaneously in cases of emergency, a switch mechanism is provided to operate the emergency switches with which each door is provided. The motor is cut out when the door has reached either the upper or lower limit of its travel, and, as the door closes, it operates a switch which partially closes the circuit of a lamp which lights up when a button is pressed. Each door may be closed by hand mechanism consisting of a pinion D<2>, Fig. 1, on the shaft D', which meshes with the pinion P on the same shaft as the pinion P<1>.The pinion P' gears with a pinion Q on the shaft Q<1>, which projects through the bulkhead and is turned by means of a hand-wheel attached to it on one or both sides of the bulkhead.

Title: Sharpening Machines for Razor and other Blades.
Inventor: SCHEUBER AUGUST WILLIAM
Filed: 1904-09-20
Granted: 1904-11-10
Abstract: 20,247. Scheuber, A. W. Nov. 12, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Sharpening.- Apparatus for stropping r a z o r and other blades is constructed with a frame 1, Figs. 2 and 3, provided with a handle 2 a n d carrying a stud 3, on which the blade-holder 4 is freely mounted, and spindles 5 on which rollers 6 are mounted. The blade. holder consists of a pair of jaws 14 of stiff metal having one or more perforations 15 to give flexibility, and shaped to grip the blade approximately at the middle of its length and width, thereby permitting it to adjust itself so that the whole length of the edge will bear uniformly on the strop. A circular rack 9 mounted on a pivot 10 on the frame 1 engages a pinion 11 fixed to the blade-holder, and is connected by links 12 to lugs 8 projecting from the rollers 6. In applying the apparatus, the rollers 6 are moved backwards and forwards along the strop, and, in the first part of their movement, during which part they roll, the lugs 8 act through the links 12 to oscillate the rack, whereby the pinion is rotated to bring the edge of the blade on to the strop. The arrangement of the lug, lever, and rack give a togglejoint effect, thus enabling the frictional action of the strop on the rollers 6 to bring the blade into contact with the strop slowly, and then hold it firmly. A spring 16 bearing against projections on the rack 9 may be arranged to return the rack to its central position when the machine is removed from the strop ; or a coil spring fixed to the pinion 11 and its extended ends bearing against opposite sides of the pivot 10 may be employed for this purpose. In some cases, the apparatus may be made with a single roller 6, being then singleacting, i.e. moved along the strop in one direction only ; or a friction device or devices other than a roller or rollers may be employed to operate the rack.
