Title: Improvements in and relating to Methods of and Means for Preparing Leases for Warp-uniting Machines.
Filed: 1907-05-09
Granted: 1908-05-11
Abstract: 10,803. Barber & Colman, Moore, J. E., and Walkden, W. May 9. Loom warp threads, uniting; yarns, leasing.-To prepare leases &c. for warp-uniting machines, the lease comprising the cloth end, yarn, reed, and harness is removed from the loom and placed on a special frame or on the loader of the warp-uniting machine, where it is stretched and straightened and then secured in holding means for presentation to the warp-uniting machine. The special frame a, Fig. 1, is provided with brackets b, which carry a grooved reed-supporting beam c. The reed is held in position by clips e on a shaft f controlled by a foot-lever, and a cross-beam h carries brackets i for supporting the healds at j, the lease-rods at k, and a comb backing at m. Notches n on the bracket are provided for the bars of the automatic stopmotion when one is used. The warp is led over a tongue-clamp s and over a carded or plush-covered quadrant or drum p having an operating-lever x and spring catch y. The warp threads are brushed over the quadrant p, which is then rotated to stretch the yarn. The lease-rods are then moved to bring the crossing above the comb backing, a comb is inserted, the lease-rod nearest the quadrant is removed, and the yarn is combed. A tongue is then inserted in the clamp s, and the lease is removed and is fixed, when convenient, in the clamps of the warp-uniting machine. In a modification, the loader of a Colman warp-tying machine is used, and is provided with a reed support c, Fig. 3, and a shaft f, which carries clips for the upper bar of the reed. The shafts may be provided with a small band-wheel 5 or a lever, and the brackets 6, which serve as harness supports, may be carried by extensions of the brackets 4. The yarn is brushed and straightened and passes over the shields 7, 8 of the loader and over a card or plush &c. stretching-device, such as the carded block 9, on the spring-actuated lever 10. Or a roller or quadrant brush, mounted to rotate, may be used. After the yarn has been stretched and straightened &c., the clamps of the tying-machine are lowered upon it and the yarn is fixed in them, the clamps with the stretched yarn being then presented to the warp-tying machine in the usual manner. In the Provisional Specification, another form of apparatus is described, wherein the lease is stretched from the cloth or tab end. Specification No. 6678, A.D. 1907, is referred to.

Title: A Board on which to Play Games.
Inventor: FLINT ALFRED TENNYSON
Filed: 1907-05-14
Granted: 1908-01-16
Abstract: 11,216. Flint, A. T., and Fanshaw, E. May 14. Games played with boards.-The surface of a board for playing games is marked out into squares some of which are cut out so that a piece may not occupy them. These cut-out squares are closed by hinged traps C balanced by counterweights E. A piece placed on one of these squares would weigh down the trap and disappear beneath the board the trap automatically reclosing the opening. Some of the traps may be made fast by means of an endless steel band F passing over rollers G. Projections H on the tape engage the edges of some of the traps and keep them fairly closed. By means of a handle I connected to one of the rollers, the band may be adjusted so that a player cannot tell which traps are fast or which will allow the piece to fall through and be lost.

Title: Improvements in or relating to Rotary Engines.
Inventor: THOMPSON WILLIAM HENRY
Filed: 1907-05-21
Granted: 1908-02-27
Abstract: 11,835. Thompson, W. H. May 21. Movable-abutment type. -Relates to a steamengine of the Root'sblower type, which is combined with an auxiliary gasolene or other internal-combustion reciprocating engine, so that, when desired, the rotary engine and its shaft can be driven by the auxiliary engine. The rotary engine described comprises a pair of pistons 4, 5, which are toothed and provided with co-operating projections 7 and recesses 8. Steam is admitted at the ports 15 and exhausted at 16, or vice versa, according to the direction of running as determined by a four-way valve 21, which communicates with the steam and exhaust pipes 19, 20. For working compound with a second engine 2, Fig. 3, steam is taken from the ports 25, and is distributed to the inlet ports of the second engine by a similar four-way valve 29. The two valves 21, 29 are coupled together by gear 33, 34, 35, 36. Fig. 6 shows the clutch by which the auxiliary reciprocating engine 14 may drive the main engine. The outer cone 42, when the clutch is in gear, is held in contact with the inner cone 40 by a spring 48, or by the weight on the arms 43 when the shaft 12 is vertical with the arms hanging downwards. When too great a speed is attained, the clutch is opened automatically by the arms 43 as they are moved outwards by the centrifugal force. When not in use, the arms 43 are held in the inoperative position by a stop 47. The outer surface of the engine casting may be round as shown in Fig. 3, or angular as shown in Fig. 4. In the latter case, brackets 50 are provided and the engine may be supported in either a vertical or an horizontal position.

Title: Improvements in Alternating Current Electric Motors of the Repulsion Type.
Filed: 1907-06-05
Granted: 1908-09-03
Abstract: 13,073. British Thomson-Houston Co., [General Electric Co.]. June 5. Motors, alternating - current ; sparking, preventing. - To improve the commutation and power - factor of a repulsion motor, especially at speeds above synchronism, the rotor is given a fractional-pitch winding and the brushes are so placed that the complement of the angle between the axes of short-circuit and primary magnetization bears to ninety degrees a ratio which approximately equals the pitch fraction. Thus, with a twothirds pitch, the angle between the axes would be thirty degrees. Fig. 1 shows a bipolar motor of half pitch, i.e. having rotor coils spanning ninety electrical degrees, in which the two sets of stator coils a, a' are wound in corresponding arcs of ninety degrees and produce respectively vertical and horizontal fields of which the line X-X is the resultant direction. The arrowheads show the rotor currents which will flow for the given stator currents, and it follows that the two currents in the rotor slots aid one another under the stator coils a and oppose one another under the coils a'. Hence, the magnetization of the rotor is entirely vertical, and the effective rotor magnetizing conductors are completely compensated by the stator coils a, as shown in Fig. 2, in which the effective and ineffective rotor conductors are respectively shown as clear and black circles. Thus the power-factor is raised, and further, since the opposite sides of a coil undergoing commutation are under the same pole of the field due to the windings a<1>, their electromotive forces due to cutting this field neutralize and the commutation is improved. The torque-producing field at rightangles to the effective short-circuit axis is due entirely to the stator coils a<1>, and the field due to the rotor currents, being due only to two short belts of conductors, is flat-topped in contrast with the usual field having peaks at the brushes. Thus, the usual sparking due to the increased peaked field at speeds above synchronism is reduced. Moreover, the reactance electromotive force of a short-circuited coil under commutation is neutralized by the stator ampere-turns a which preponderate over the rotor turns in place of being augmented by them as in the usual repulsion motor. The divided stator coils a, a<1> enable the rotation to be reversed by reversal of the relative connexions of the two groups, and also enable the machine to run as a simple series motor on alternating or direct currents as shown in Fig. 3.

Abstract: 27.391. Fowler, C. H., and Medley, E. A. Dec. 11. Scrubbers and washers.- Relates to the gas-washer described in Specification No. 22,282, A.D. 1902. In place of a single revolving disk between each pair of fixed trays T, a number of such disks A, B, C, D are fixed one above the other, so that instead of a single film of water through which the gas must pass, a number of such films are produced from the peripheries of each group of disks. The bottom disk A of each group is fixed to the vertical rotating shaft S, and the upper disks are attached to the disk A, each disk having a central hole larger than that in the disk immediately beneath it. The hole in the middle of the conical tray T, above each group, is shaped as shown in Fig. 2, so that each disk receives a supply of liquid. A form of fixed tray which may be substituted for the tray T for tar separation is shown in Figs. 3 and 4 In this form, a circular gas passage L is left round the edge of the tray, and the sections of the tray that feed the several disks below are divided by radial ribs M, which also serve to fix the tray to a ring N secured to the casing of the washer. Each disk is fed with liquid in two places diametrically opposite to one another, as shown in Fig. 4.

Granted: 1909-06-17
Abstract: 13,075. Mort, G. F. June 19. Gas and explosive-vapour engines.--To reduce, or obviate entirely, the necessity for water-cooling in two- and four-stroke-cycle single or double acting engines suitable for motor road vehicles, ships, or aeronautics, large volumes of charging and scavenging air, from four to six times that of the effective volume of the cylinder, are supplied by a forcing or inducing fan driven from the crank-shaft, the cylinder valves or ports being of sufficient area to permit the air to travel at the rate of about 100 feet per second. In the two-stroke-cycle engine shown in Fig. 7, air is supplied to the cylinder by a fan A through an inlet valve I, and escapes with the exhaust gases through piston-controlled ports E, the depth of which is approximately equal to onehalf the stroke of the piston. In a modification, both the inlet and exhaust ports are provided at the end of the piston's out-stroke, the fuel inlet valve H being located in the cylinder head. The supply of fuel to two-stroke-cycle engines is preferably commenced before the closing of the exhaust ports. Fig. 11 shows a four-stroke-cycle engine having double-beat inlet and exhaust valves I, E respectively. The exhaust valve opens a little before the crank reaches the bottom dead centre, and is followed at the end of the stroke by the opening of the inlet valves, both valves remaining in these positions, preferably, until late in the second out-stroke ; at any time after this, fuel is injected, but with advantage early in the compression stroke.

Title: Improvements in the Process of and Apparatus for the Manufacture of Cast Metal Wheels.
Inventor: GRUNWALD CARL
Filed: 1908-10-12
Granted: 1909-02-04
Abstract: 16,956. Grunwald, C. Oct. 12, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Casting.-Wheels, cast in metal moulds comprising several parts, are almost completely exposed on the relative axial movement of the parts of the mould, which is effected as soon as the casting is set sufficiently to retain its shape. Fig. 1 shows a mould comprising upper and lower members A, B and a support C for the core F and also for the lower side of the wheel hub. The member B is supported upon a hollow hydraulic ram H. After the casting operation, the ram H is lowered until the upper member A is supported on the fixed framing E by means of the arms a<2>. The casting and the member B are lowered together until the longer inner ram N reaches the bottom of the ram cylinder G, so that the head n' forms a rigid platform for the hub support C. Further lowering of the ram H then withdraws the member B from the casting which is left almost completely exposed. The support C in this case is removable, but it may be attached to the ram head n'. A projecting ring a' on the member A fits into a corresponding recess on the member B to enable these members to be positioned correctly before each casting operation. In a modified form of apparatus only one ram is used, and that supports the lower half of the mould. The support C in this case is similar to that shown in Fig. 3, and is lowered on to a ring of fixed pillars, which pass through openings in the head of the ram as the latter is lowered. The member A in this case is supported in the manner previously described. Fig. 3 shows a mould having an upper member A supported from a bar K. Clips O secure the members A, B together during the casting operation. When the wheel is set, the member B is lowered by hand. During the lowering operation the dished supporting-member C' falls on to the fixed block M and supports the casting, while the member B is lowered still farther to expose the casting. An interchangeable ring D is provided in this case to protect the bottom of the member C' from the action of the liquid steel. The members B, C may be provided with a lining of non-conducting material such as fire-clay composition.

Title: Improvements in the Valves and Valve Gear of Internal Combustion Engines.
Inventor: KITCHEN JOHN GEORGE AULSEBROOK
Filed: 1908-10-09
Granted: 1909-08-05
Abstract: 21,317. Kitchen, J. G. A. Oct. 9. Gas and like engines.-Admission and exhaust are controlled by two oppositely-rotating ported liners 5, 6, arranged between the piston and the cylinder. Figs 2
 and 2<e> are sections through the admission and exhaust ports s, e, Fig. 1, respectively, with the liners in the position they occupy at the commencement of the admission stroke of the four-stroke cycle. In the arrangement shown, the liners rotate at one-fourth the speed of the crank-shaft, and each has two admission ports and two exhaust ports. With this arrangement the pressures on the liners are balanced throughout the cycle. In another arrangement the liners are rotated at half the speed of the crank-shaft, and each has a single admission port and a single exhaust port. The admission ports can be shortened so as to open late and close early. The delayed opening causes a partial vacuum and a strong rush of air through the carburettor. The exhaust ports may be lengthened so as to open before the end of the power stroke. Packing-rings 24, 25 are provided between the admission and exhaust ports. The clearance in the cylinder is reduced by an extension on the piston, or by a projection on the cylinder head. The liners are supported on ballbearings carried by the part 9 mounted on the crank casing, and are rotated by worms driven from the crank-shaft by chain gearing.

Granted: 1909-11-25
Abstract: 25,440. Maples, R. A. Nov. 25. Gas and like engines.-Multiple-cylinder fourstroke-cycle double-acting engines are started by air or other fluid under pressure without interfering with the four-stroke cycle. The compressed fluid is admitted to each cylinder during the workd stroke, and is automatically cut off by the explosion pressure when firing commences. Valve-gear for starting, stopping, and reversing is described. s, Starting ; stopping reversing.-The inlet and exhaust cam-shafts 37, 58, Fig. 3, are driven by the engine shaft 25 through worm gearing 39, 59. The rods 31, 52, 33, 83 for actuating the inlet valves, exhaust valves, ignition gear, and compressed-air valves, respectively, rest upon arms 34, 53, Fig. 3, having at their outer ends rollers 36, 54 actuated by the cams on the shafts 37, 58 through selector rollers 46, 57, Fig. 3, carried by arms 45, 55 mounted on intermediate shafts 44, 56. To enable the cams to be thrown into and out of operation, the intermediate arms 45, 55 are raised by cams 76, 77, Figs. 3 and 9, on shafts 71 which are moved together by the lever 74 and link 73. The shafts 44, 56 are then moved axially by the lever 64, Figs. 5 and 6, pinion 66, and rack 67 so as to bring the selector rollers over the proper cams. Upon the exhaust side of the engine, Fig. 1, is a pipe 79 for conveying fluid under pressure to valve casings 81, each containing a mechanically-actuated valve 82 and a non-return valve 84 in the passage leading to the cylinder. The inlet-valve cams are shown at 41, 42, Fig. 5, the exhaust valve cams at 60, 61, Fig. 6, the ignition eccentrics at 47, and the compressed air-valve cams at 89. Compressionrelief cams 63 are placed opposite the exhaust cams. With the lever 64 in mid - position, the selector rollers will run on cylindrical, surfaces and will not be raised. The engine is started by moving the lever one notch of the quadrant 70. One of the valves 82, the cams of which work in alternation with the inlet-valve cams, will during a working- stroke admit air which will be exhausted on the next stroke. On the third stroke, rotation being effected by another cylinder, a charge is introduced which is compressed on the fourth stroke, compression being relieved by the cam 63. On the next stroke air is admitted again. This cycle continues until the charge in a cylinder is in a condition to be exploded. The explosion pressure will then close the valve 84, thus automatically cutting-off the compressed - air supply. Having started the engine, the lever 64 is moved to the second notch ; this throws the cams 89, 63 out of action without affecting the inlet and exhaust cams. Reversal is effected by moving the lever 64 in the opposite direction.
