Granted: 1903-08-20
Abstract: 14,267. Meier, G. June 27. Gas valves and cocks; reducing-valves; automatic cut-offs for gas cocks; actuating valves ; diaphragm valves ; plug cocks; multiple-way valves and cocks.-In an arrangement for lighting staircases &c. for a short time, a pressure-reducing valve c is included in the main conduit a, b. One side d of the valve communicates with the atmosphere through a cock f, to which it is connected by a small tube e. The casing of the cock is also connected to the conduit a by a tube g. The plug f is provided with three holes and also a longitudinal slot for connecting the tubes e, g. Two passages lead from the plug f to a smaller plug m, which is provided with a transverse bore and a longitudinal slot. The transverse bore enables one of the passages from the plug f to communicate with the atmosphere through a tube, the orifice of which may be regulated by a setscrew l. The small plug is held in its normal position by a spring k, and is operated by a button i. During the evening, the plug f is turned into the position shown in Fig. 2. The gas from the conduit a passes by the longitudinal slot in the plug to the back of the diaphragm, and by its pressure fully opens the valve c. During the night, when only temporary lighting is required, the plug f is turned as shown in Fig. 4. The valve c is then open just sufficiently to keep the bye-pass burning; or, if an automatic igniter is used, the valve will be shut. When the cock m is turned as shown, gas from the conduit a passes to the back of the diaphragm and opens the valve c. On releasing the button i, the cock m returns to its original position, the back of the diaphragm being now in communication with the atmosphere. The enclosed gas escapes into the atmosphere more or less slowly, according to the position of the set-screw l, and the valve c is gradually closed.

Title: Improvements in Adding Machines.
Inventor: EBERHARDT HERMANN
Filed: 1904-05-04
Granted: 1904-08-18
Abstract: 10,264. Eberhardt, H. May 4. Calculating-apparatus.-An adding-machine has one wheel for each column of figures. In one arrangement, Figs. 1 and 2, the counting-wheels a, b, c, d are mounted in boxes e, f, g, h open on adjacent sides, the box e being fixed to a pillar i, whereas the other boxes are supported by pieces m pivoted to the boxes and to the case, and are retained in position normally by springs n. Discs p fixed to the wheels have the numerals marked on them in positions corresponding to the teeth of the wheel, and also to the holes r arranged circularly on the discs. Each wheel, except that at the left-hand end, carries a tooth t sliding in a groove and having a pin v which works in an elliptical groove u in the bottom of the box, so that, when the wheel is revolved, the tooth moves inwards and outwards so as to turn the next wheel the space of one tooth in each revolution. The top of each box is provided with a nearly-circular aperture round which the numerals are marked on the box. The wheel a records units, the others tens, hundreds, and thousands. A stick s is inserted in the hole in the wheel opposite the required figure in the proper box, and the wheel is revolved till the stick meets the stop. This is done for each figure of the numbers to be added. The pressure on any one of the wheels b, c, d when the stick is inserted causes the box to be displaced, so that the wheel is only connected with that on the left-hand side. The sum of the numbers is read off from the figures appearing through the apertures in the boxes. In the form shown in Fig. 3, all the boxes are fixed, and the number discs have ratchet-wheels a<1>, b<1>, c<1> attached to them, and also discs G, each carrying a driver t which once in each revolution displaces a spring- lever K by means of a pin L. The lever moves the next ratchet-wheel, by means of a spring- pawl N, through the space of one tooth. A second spring-pawl R prevents reverse movement. In this case, all the wheels revolve in the same direction.

Title: Improvements in Gas Producers.
Inventor: SCHWEICH EMILE
Filed: 1904-05-16
Granted: 1905-02-23
Abstract: 11,268. Schweich, E. May 16. Gas-producers.-Relates to a combination of an up-draught aud down-draught gas-producer, in which steam and air are admitted both at the top and bottom of the fuel chamber, while the resulting gas is led away by an exit situated in a position midway between the blast inlets. One form of gas producer, shown in Fig. 1, consists of a generating- chamber A, having the lower part of one wall sloped, and extending beyond the upper vertical part of the wall, ana thereby forming a space 11, opening into a gas exit 4. Steam and air are supplied to the base of the producer by the pipe 3 and to the top by the pipe 2. Grates 6,12 are provided opposite either or both of the air inlets. The lower part of the producer terminates in a water lute 7, from which ashes and the like are with drawn. A modified form of producer, shown in Fig. 2, has two upper generating-chambers 9, each provided with air and steam inlets 2. Air and steam inlets 3 are also provided at the base of the generating-chamber A, and the exit 4 is situated between the upper chambers of the producer, which are formed by the construction of the walls 8. In another modification, Fig. 3, the upper part of the generator is made smaller than the lower part, the gases being discharged from an exit in connection with a space arranged between the two parts. If desired, the top grates may be dispensed with, or they may be used in each modification of the producer, and also part or the whole of the bottom blast may be introduced through a stand-pipe provided with a hood, as shown in Fig. 3.
Patent GB-190415869-A (GB)
Title: Improvements in Installations for Electrically Operating Railway Points.
Filed: 1904-07-16
Granted: 1904-11-10
Abstract: 15,869. Siemens Bros. & Co., [Siemens & Halske Akt.-Ges.]. July 16. Miniature signals.-Relates to installations for electrically operating railway points, and consists of an arrangement for furnishing a permanent indication when points have been forcibly opened by the passage of a vehicle, also of an indicator for showing agreement or otherwise between the positions of the cabin switch and shifted points, such indication being given by means of a coloured disc on the armature lever n of the switch magnet shown in Fig. 4. The permanent indication may be made by the burning out of a safety fuse, or by means of a separate electromagnet. The circuit of the point-shifting motor is closed by the switch g, which is turned into contact with the lead i, and at the same time turns the armature lever n into contact with the lead q. The full current then flows from the battery through the lead q and the motor to earth. When the points have finished their movement, the rod f connected to them will have thrown over the switches d, e, so that the current will be directed by the switch e to the lead m, and will energize the magnet k. The armature lever n will theretore be attracted, and will be shifted into contact with the lead o, so that a small current will flow through the safety fuse p, and thence through the magnet k. This current, owing to the high resistance of the magnet k, may be safely carried by the fuse p. If, however, when the parts are in the position shown, the points are forcibly opened by the passage of a vehicle, the switches d, e will be thrown over by the rod f, and the current will be directed by the switch d through the motor to earth. This current, owing to the motor offering less resistance than the magnet k, is strong enough to burn out the fuse p, which can only be replaced by tampering with a seal. Fig. 5 shows a similar arrangement in which the indication is made by means of an electromagnet s. The ordinary auxiliary current flows from the battery, through the resistance t, magnet s, and the armature lever v to the lever n, but is so small that the magnet s does not attract the lever v. When, however, the current is momentarily increased by the forcible opening of the points, the lever v is attracted by the magnets, and the circuit is broken, but the magnet s remains excited owing to a new circuit being established through the lever v and resistance y. The auxiliary circuit caanot be again closed until the lever v is separated from its magnet, and this can only be done by pushing a rod z, after breaking the seal with which the rod is fastened.

Title: Improvements in Locomotive Engines.
Inventor: WHEATLEY WILLIAM HUMPHREY
Filed: 1905-04-28
Granted: 1906-02-22
Abstract: 9016. Wheatley, W. H., [International Rail may Device Co.]. April 28. Locomotives are provided with an extra valved pipe for regulating the exhaust, which by means of a branch pipe also connects the two ends of the cylinder when the engine is running without steam. Figs. 3 and 4 show the arrangement, in which the extra pipe E, controlled by the hand operated valve 2, is carried to the top of the chimney. When steam is cut off, the check valve H automatically opens and connects the steam chest to the exhaust, through the medium of the pipes E, F, thereby connecting the two ends of the cylinder as shown in Fig. 4. This arrangement reduces condensation in the cylinder by preventing cold air from being drawn m at each stroke. Steam which leaks past the throttle valve is conducted by the pipe E to the top of the chimney and does not increase the draught through the furnace.
