Title: Improvements in Internal Combustion Engines using Liquid Fuel.
Inventor: HIGHFIELD JOHN SOMERVILLE
Filed: 1904-01-25
Granted: 1905-01-12
Abstract: 1806. Highfield, J. S. Jan. 25. G a s or explosivevapour e n g i n e s.-A two-stroke cycle oil engine is shown in Fig. 4. Two cylinders are mounted on the same bed-plate, one on each side of the air-compressor shown in Fig. 3, all three cylinders being connected to one crank shaft with cranks at 120‹ to reduce vibration. The cylinder is jacketed at d and contains a piston on the top of which is a block f used for igniting purposes. Ignition may be effected at starting by any suitable means, e.g., platinum wires. The liquid pump is shown at the top of the cylinder, in which a lever 12, actuated by a rod 24, lever 22, and a cam 19 on the crank shaft, and controlled by a spring 18, operates the valve 9 shown in Fig. 5. The rod 10 is cut away at 13 and is bored to receive the fluted valve-spindle 6 of the valve 9 which is fitted with a spring 8. A non return valve 15 controls the fuel supply. A dash-pot is provided in which the air outlet can be adjusted so as to vary the time of closing of the valve. The amount of travel of the valve can be altered by turning the shaft 20, Fig. 4. As the piston descends it first uncovers the exhaust port v and a charge of cool air expels the products through the inlet port u almost immediately after. As the piston ascends, this air is compressed to about 140 or 200 lbs., and a portion finds its way through the openings 4, Fig. 5, where it meets fuel from the valve 15 and breaks it up. As the piston ascends further, the lever 12 causes the plunger, Fig. 5, to force this rich charge into the cylinder. The valves are now all closed for the working stroke. A nut on the rod 24 provides a means of regulating the speed. The air pump is shown in Fig. 3 in which q is the inlet and t the outlet passages and r, s the valves, and o the crosshead guides. The pressure in the air cylinder, Fig. 3, being small, about 10 lbs., the connecting-rods are always in compression. A separate air pump may be used, and the engine may be started, by working the pump, Fig. 3, with compressed air.

Title: Improvements in Alternating-current Electric Motors.
Inventor: DAVIES FREDERICK WILLIAM
Filed: 1904-05-28
Granted: 1905-03-30
Abstract: 12,123. Davies, F. W. May 28. Motors, alternating-current; armatures; commutators.-To obtain a powerful starting-torque, especially in motors for use on single-phase circuits, those coils of the rotor which occupy an oblique position with respect to the stator field are connected in series or series-parallel so that the current circulating in them produces rotation in one direction only. In Fig. 1, the rotor is wound preferably with an even number of coils having their ends connected to diametricallyopposite commutator bars, and alternate coils are either wound in the opposite direction to the rest, or the connections of the ends of consecutive coils to the commutator bars are reversed. The brushes J, K are equal in number to the magnet poles, and are set apart at an angular distance corresponding to the polar pitch. In the modification shown in Fig. 2, the rotor is preferably wound with an odd number of coils, and opposite commutator bars are connected together. One end of each coil is connected to a pair of commutator bars, the other ends being bunched together at S. One brush or set of brushes T only is required. An ordinary squirrelcage winding may be combined with the winding shown in Figs. 1 and 2, which, when the motor has reached its normal speed, may be placed out of action by lifting the brushes ; or the winding itself may be short-circuited on attaining normal speed, this being effected in the case of the winding shown in Fig. 1 by connecting the commutatator bars to insulated slip-rings carrying brushes which are connected to a suitable short-circuiting switch. With the winding shown in Fig. 2, each pair of commutator bars and the junction S would be connected to a slip-ring. To render a larger number of the rotor coils operative at full speed, an extra set of brushes of high-resistance material may be placed on the commutator to shortcircuit those oblique coils which, at starting, oppose the coils connected in series by the brushes J, K.

Patent GB-190428310-A (GB)
Title: Improvements in and relating to Syphon Lubricators.
Inventor: HOMMERSHAM THOMAS HENRY COLLET
Filed: 1904-12-27
Granted: 1905-04-20
Abstract: 28,310. Homersham, T. H. C. Dec 27. Lubricators.-To enable the flow of oil in a siphon lubricator to be cut off at will without necessitating access to the interior of the oil cup, external shut-off means are provided by a shaft G under the base B of the tank A. The oil is siphoned by fibrous material into the tubes D attached to the bed of the tank A, and is led through apertures C and tapering nozzles E by a visible feed to the delivery tubes F. The shaft G, rotatably mounted in a bush extending under the holes C in the tank base, has holes H formed at right-angles to its axis ; and so disposed that when vertical they form a connection between the apertures 0 and the nozzles E, but, when the shaft is turned through a right-angle by the handle K the holes lie as shown in Fig. 1 and effectively cut off the supply of oil. Flat lugs K<1> on the handle K, retained in position by a spring L, indicate the "open " and "shut positions of the shaft G. Instead of rotation, longitudinal movement of a shaft held by a spring may be substituted, circular grooves H', Fig. 4, replacing the holes H. Raising the handle P in this case draws the grooves H<1> forward and into coincidence with the oil passages, a spring N drawing the shaft back when the handle is dropped. The positions and sizes of the holes or grooves may be arranged that one or more of the lubricators can be put out of action without interfering with the rest.

Title: Improvements in Treating Wood for Preserving and like purposes
Inventor: WEED EDWARD BEVERLY
Filed: 1904-12-29
Granted: 1905-04-06
Abstract: 28,729. Weed, E. B. Dec. 29. Wood, treating for preserving &c. - Wood is prepared for preserving or other treatment such as dyeing by first driving out part of the natural constituents, such as water, resins, &c., in a bath of resin, a non-volatile hydrocarbon, or similar substance which has a relatively high boiling point and a melting point below the temperature attained by the wood, to prevent the formation of a coating on the wood. The wood while still hot is treated with gasoline, alcohol, or other neutral non-aqueous solvent of resins, terpenes, aud other remaining natural constituents of the wood, and the solution thus formed is expelled by immersing in a heated bath of resin or other material having a higher boiling point than the solvent. The wood is then removed to a bath containing the preservative or other fluid. Long leaf pine is treated in a bath of resin at 320‹ F. from two to six hours, and then with gasoline at normal temperatures from less than one hour to more than twelve hours according to the nature and thickness of the wood. The wood is then immersed in a bath of resin at 320‹ F. or at lower temperatures, and then in the preservative fluid from a few hours to one or two days according to the degree of saturation required.

Title: A Method and Means of Converting and or Transforming Continuous Currents of Electricity.
Inventor: GRISSON ROBERT
Filed: 1905-03-24
Granted: 1906-03-24
Abstract: 6307. Grisson, R. March 24. Converting alternating and direct currents; transformers; wireless telegraphy. - An improved unipolar cell of the aluminium type or its equivalent is used to change continuous currents into alternating, pulsating, or intermittent currents. The cell consists of a sheet of aluminium wound into a spiral or folded zigzag, and immersed in dilute sulphuric acid contained in an iron vessel. Figs. I and II show the arrangement of circuits employed in connexion with a source G of continuous current. When the arms of the two-way switch c are to the left, a current flows through the consuming-device v into the unipolar cell u or its equivalent. After the cell is charged, the switch levers can be turned to the right without sparking, and a current flows through the consuming-device in the opposite direction. With the arrangement shown in Fig. II, unidirectional current impulses pass through the consuming-device. The switch c may be replaced by a rotating commutator switch as shown in Fig. III, the segments L<1>, L<2> being alternately in connexion with the slip-rings S<1>, S'. High-pressure continuous current may thus be converted into alternating current of lower pressure for cauteries, incandescent lamps, faradization apparatus, &c. In Fig. IV, the primary coil of a transformer is used as the consuming-device. A second unipolar cell may be used where the source of current supply has a high induction or resistance, Fig. V. A third unipolar cell may be connected in parallel with the consuming-device v and cell u, Fig. VI. The best effect is obtained when the self induction of the consuming-device is brought into resonance with the capacity of the cell. A modification of the arrangement shown in Fig. III has the consumer v placed within the continuous-current circuit. When, in an arrangement such as that shown in Fig. V, the consuming-device is the primary coil of a transformer placed in the continuous-current circuit, currents are obtained suitable for Rontgen rays, high-frequency currents, wireless telegraphy, &c. [Reference has been directed under Patents Act, 1902, to Specifications No. 1537, A.D. 1889, No. 18,865, A.D. 1900, and No. 17,885, A.D. 1902.]
