Title: Improvements in and relating to the Manufacture of Gas Consisting Chiefly of Methane or Marsh Gas, for Illuminating, Heating and Power Purposes and in Apparatus therefor.
Inventor: ELWORTHY HERBERT SAMUEL
Filed: 1902-05-31
Granted: 1903-06-30
Abstract: 12,461. Elworthy, H. S., and Williamson, E. H. May 31. Hydrogen, for use in the manufacture of a gas consisting principally of methane, is prepared by alternately oxidizing and de-oxidizing metallic iron. This takes place in a brick-lined metallic rectangular chamber 25 having an arched top. At its lower end are inlets, for heating-gas 34, for reducing-gas (preferably that obtained in the producer), for air 39, and for steam ; a manhole is also provided. At its top are outlets for hydrogen and waste gases respectively, and a manhole for charging the trays 41. On the floor are rows of pillars 37, supporting square trays 41 of refractory firebrick containing the iron in the form of powder. The space 38 forms a combustion chamber. Each tray is of I-section, the adjacent flanges resting on the pillars. The trays in each alternate layer do not reach to the opposite walls, thereby providing a zig-zag course for the ascending gases. The outer trays have speciallyshaped outer flanges, which rest upon ledges 42, as shown in Fig. 3. The chamber may be constructed without a combustion chamber, in which case it is heated by a hot-air blast. The carbonic acid produced when reducing the oxide formed may be collected and purified.

Granted: 1903-05-14
Abstract: 12,731. Mellor, J. W., and Wolstenholme, L. June 4. Seats. -In outdoor seats with reversible backs, the bottom consists of two layers a, b, of wood or other material, so connected by cranks or hinges c that the top layer a may be lifted up from either edge. The top layer, in its raised position, bears against the back-rest e, and is held up by the back of the occupant, falling automatically on the lower layer when the seat is vacated. In dry weather the top layer is left on the lower layer, and forms the saat. The cranks or hinges may be applied at the ends of, or between, the layers. The bottom layer may be plain, perforated, or formed of strips. Instead of allowing the top layer to bear against the back-rest, the cranks or hinges may be formed with abutments which limit the angle through which the top layer may be turned.

Abstract: 14,801. Washington, W. H., Stanton, G. M., and Woore, R. July 2. Metal pipes and tubes jointing with internal ferrules.-Relates to a heating and protecting system for pipes, fire-plugs, hydrants, and other water or fluid containers and conductors. A series of jackets 7, which are independently removable from, and surround, the pipe 8 or other object to be protected from frost, are provided in combination with heating means, which may be an air-heating furnace, as shown in Fig. 1, or steam boiler, gas burners, oil burners, or electric heaters may be employed to supply the heat. The jackets consist of sheet-metal tubes, Figs. 1 and 2, with edges bent over to form grooves to receive the tongues 15, 16 on the coupling or retaining strips 17, which are adapted to be applied to or released from the jackets by an endwise sliding movement. The jackets are removably connected together by the coupling - devices 18. Each coupling-device 18, Fig. 7, has segmental perforated flanges 21, forming portions to bear against the pipe and to hold the jackets centered thereon, and beads or rims 19, against which the ends of the jackets abut. The tubular jacket coupling-pieces may be in two parts, which are bolted or hinged together, there being grooves in the faces of the coupling-pieces to receive the jacket ends, or the jacket ends may be flanged and bolted to the external rim or flange of the tubular jointing- piece. The jackets 7 may be formed in halves with flanged edges to receive on either side locking or retaining strips. Fig. 5 shows another form of jacket, having the straight edges 25, 26 engaged by the V-shaped bar or strip 27, which receives the keys 29 to hold the parts together. In another modified form of jacket, the jacket is in two parts and the edges engage grooves in double-grooved coupling or retaining strips. An elbow jacket, having a bolting-flange and an apertured pipecentering flange, is preferably employed at angles. Lugs, instead of flanges, may be formed upon the jacket to hold the pipe 8 centered.

Title: Improvements in or relating to Regulating Devices for Dynamo-electric Machines.
Filed: 1902-07-30
Granted: 1903-07-30
Abstract: 16,904. Lake, H. H., [General Electric Co.]. July 30. Dynamos, regulating.-Relates to regulating-devices for dynamo-electric machinery, and especially for boosters used in railway, lighting, and powerdistributing systems to compensate for the drop in the feeder lines &c. The booster is driven in any manner, and is provided with an auxiliary field winding which is supplied with current from a moderately-constant source. This current is controlled automatically to regulate the booster in such a manner that the potential at the distant point to which the booster is connected is maintained constant. The main and auxiliary field windings may act in conjunction or in opposition. In the example of the arrangements shown in Fig. 1, the booster 11 and its series winding 12 are connected by a feeder 9 to a distant point 10 in the main 6 connected to the generator 5, and the auxiliary winding 13 is in series with a large adjustable resistance 14 across a suitable source of current, such as the mains 6, 7. An electromagnetic make-and-break device, shown as an electromagnet 16 and a vibrating armature 15, is connected to the points 10, 25 between which a constant potential difference is desired, and is used to short-circuit the resistance 14 when the current in the winding 13 requires to be increased. When the potential at the point 10 is excessive, the armature 15 is drawn back from its contact 19 and the current in the winding 13 is reduced, the final effect being that the voltage of the booster 11 and at the point 10 falls. A condenser 20 is used to reduce sparking when the contact-maker is in action. If the winding 13 acts in opposition to the winding 12, the armature 15 is arranged to bear against the contact 19 when drawn up to the magnet 16. Fig. 5 shows a modification, in which the current through the auxiliary winding 13 acts in opposition to that in the winding 12, and is varied by the use of a resistance 24 shunted across the winding 13 or the resistance 14. When the armature 21 is on the contact 22, the winding 13 is short-circuited by the resistance 24, but, when it is on the contact 23, the resistance 24 is cut out and the resistance 14 is short-circuited through the armature. This arrangement may also be modified to suit the case in which the windings 12, 13 act in conjunction.

Granted: 1904-04-07
Abstract: 8766. Harvey, E. C. April 17. Beer and other beverages, raising and drawing- off.-Beer or the like, during its passage to the beer engine or tap, passes through a chamber which is supplied with carbon dioxide under pressure. Fig. 2 shows a vertical section through the principal parts of the apparatus used in connection with a beer engine. The pump cylinder b is connected, by the pipe b<4>, with the expansion chamber c connected to the gas cylinder d. The needle valve g, Figs. 2 and 6, formed on a screw-threaded spindle g<1>, is normally held in its closed position by the spring g<5>, and is opened by the descent of the lever h, which carries a pivoted pawl h<2> adapted to operate the arm g<4> on its descent and to turn and slip past on its ascent. The piston-rod b<5> carries a bar i having a projection i<3>, which, as it rises, engages the pivoted pawl h<1> and turns the spring-held lever h through a certain distance. On the descent of the bar i, the projection i<3> slips past the pawl h<1>, and the pivoted pawl i<4>, which is controlled by a stop i<5> and spring i<6>, turns the valve j by means of a horizontal projecting arm j<6>. The valve comprises a bevelled plug seated within the gas-inlet pipe, but is otherwise constructed in a similar manner to the valve g. In a modification, the aÙrated liquid is drawn off through a tap connected to a mixing- chamber placed above the pump. cylinder, and the mixing is effected by vertical arms connected to a screw-threaded piece, which is free to rotate, is prevented from moving longitudinally, and is mounted on a screw-threaded portion of the upper part of the piston-rod. In a second modification, the beer is supplied under pressure, due to gravitation or otherwise, the pump is dispensed with, and the valves are operated by linkwork connected to the draw-off tap. The expansion chambers may be dispensed with.

Granted: 1904-09-01
Abstract: 22,008. Boyden, T. L. Oct 13. Field magnets of multipolar generators and motors. Consists in dividing the radial magnet cores into sections having different degrees of magnetic saturation for the purpose of preserving the magnetic symmetry of the pole faces and of preventing cross-magnetization. In one arrangement, Fig. 1, the core A projecting from the yoke ring B is divided obliquely so that the pole tip D which has been most weakened by the armature current is more or less saturated, or the core may be symmetrically divided into three portions whereby both pole tips are maintained in a saturated condition and are separated by an area of low density. When laminated magnets are employed, the same division of the individual plates is adopted, and the plates are preferably piled alternately. In a modification, Fig. 4, the pole tip E is formed by a narrow pile of plates which may be separated by gaps of air or other non-magnetic material, or the plates may be piled alternately, or, as shown in Fig. 3, plates of different widths may be superimposed in regular order in such a manner that the central portion of the core consists of solid plates, the proportion of air-gaps increasing in the outer zones. The plates are spaced apart, where necessary, by the insertion of non-magnetic material.

Granted: 1904-08-25
Abstract: 22,318. Mitton, T. E. Oct. 16. Lubricators.-Mechanically-operated piston or plunger lubricators for forced lubrication are so arranged that they may be independently refilled and adjusted to deliver any required quantity of lubricant. A series of cups A are placed upon a vessel B and communicate therewith by passages P<111> controlled by a valve V. The piston P of each cup is attached by means of a sleeve S and a nut N to a screw S', which has a collar C bearing against the underside of the cover C' ; this cover is bolted to the cup. A worm-wheel W, loose on each screw, bears on the upper side of the cover C' ; the wheel gears with a worm W<1> operated by ratchet-mechanism to force the lubricant to the required place, and it is connected to the screw by means of a bolt B' passing through the handle H. The feed is regulated by means of an adjustable quadrant Q, on the shaft of the ratchet-wheel, engaging a pin x on the pawl P', to cause the pawl to miss some of the teeth covered by its movement. When the bolt B<1> is withdrawn and the valve V opened, each cup may be refilled by rotating the screw S' and raising the piston. The bracket B<111> is provided with projections in which a feather F on the sleeve S works, so that the piston is prevented from rotating with the screw until it has reached its full stroke; the feather is then released, the piston is free to rotate, and overwinding is prevented. A relief valve R<11> is fitted to each cup. The vessel B is filled through the pipe K. The stand pipe S<111> of each cup has a delivery piece D, to which the required number of sight-feed distributers D<1> are attached. The worm shafts may be placed longitudinally and coupled together, one ratchet-wheel then operating two or more cups. According to the Provisional Specification, the projections may be pivoted to the bracket B<111>.
