Title: Improved Means for Producing Rapid Reciprocating Motion.
Inventor: BOYS CHARLES VERNON
Filed: 1907-12-11
Granted: 1908-12-11
Abstract: 27,361. Boys, C. V., and Tierney, J. W. Dec. 11. Compressed-air engines. -Relates to means for producing rapid reciprocating motion of a heavy body without undue vibration in cases where very little external work is required. A piston is reciprocated in an elastically held cylinder by means of an elastic-fluid spring formed by air trapped in the ends of the cylinder, means being provided to maintain reciprocation by making up energy losses. When the system vibrates, its centre of gravity remains practically at rest. Figs. 2, 3, and 4 show one method of producing and maintaining reciprocation. The cylinder c is mounted on flat springs 1 fixed to an adjustable bracket. Motive fluid is admitted from a port q, between differential piston heads m, n, and raises the piston to the grooves r. Motive fluid then flows through a passage 2 to raise the valve s and thus close the restricted exhaust ports v. More live air passes from the grooves r to the space above the piston and forces the latter downwards, compressing air in the space 3. When the pressure in the upper cylinder end falls sufficiently, the spring t forces down the valve s, and exhaust takes place. The air compressed in the space 3 arrests the downward motion and, assisted by live fluid between the piston ends, raises the piston again. The valve s closes at a definite point of the upward stroke depending on the velocity of the piston and the capacity of the passages v. At full speed the air compressed in the upper cylinder end becomes the effective means of returning the piston. Passages o, p are provided to prevent creeping, and a silencer may be provided. In a modification, the piston heads are equal, and, as the speed of the piston increases, the valve is cut out of operation, the passages v then being always closed, and exhaust taking place through the pistonrod. In a further modification, no valve is used, and the piston may be held until pressure is built up below it by live air passing through small holes in the piston. The piston is then released and starts upwards with high velocity. In all these modifications the air for making up losses of energy may be admitted to both ends of the cylinder or it may be utilized in an auxiliary cylinder. In another modification, electro-magnetic means are employed to maintain reciprocation. The Provisional Specification states that reciprocation may be maintained by means of a small alternating force, such as electro-magnetic forces, acting on the cylinder instead of being applied between the piston and cylinder directly. The frequency of vibration increases as the amplitude increases.

Title: Improvements in or relating to Heaters for Water and similar Apparatus.
Inventor: WADHAM ROBERT
Filed: 1907-12-13
Granted: 1908-05-21
Abstract: 27,577. Wadham, R. Dec. 13. Heating water.-The slime &c. that accumulate in the tubes of water-heaters and similar apparatus is blown out by water led into the top of the apparatus. The water-tubes, forming a series of sections, communicate at the bottom through cocks 51, leading from curved connecting-tubes, with the common blow-off pipe 58. The sections communicate two-and-two at the top through chambers 37<1> formed in a header pipe, by means of non-return valves. The header pipe is connected through the pipe 59 and the three-way cock 60 with the feed-water supply inlet 48. A safetyvalve 61 is provided on the header pipe to relieve excessive pressure during the normal working of the heater, or during the blowing off process, the non-return valves being opened by such excessive pressure. To blow off any desired section, the cock 60 is turned to lead the water through the pipe 59 into the top header, through which it flows, opening the non-return valves, and the section it is desired to clean is put into communication with the blow-off pipe 58 by opening the corresponding cock 51. Modifications are described in which the headers connecting the sections at the top separately communicate with the pipe 59 by non-return valves ; or the headers connecting the sections at the bottom communicate by non- return valves, and the sections communicate with the pipe 59 through cocks on the top headers ; or both top and bottom headers are formed by non- return valves in the top and bottom connecting- pipes respectively.

Title: Improvements relating to the Control of Alternating Current Electric Induction Motors and of the Means Driven thereby.
Filed: 1907-12-19
Granted: 1908-12-21
Abstract: 28,040. Mavor, H. A., and Mavor & Coulson. Dec. 19. Motors, controlling.-Induction motors having their stators so mounted that they may be allowed to rotate, are controlled by supplying them with intermittent or fluctuating current, the invention being particularly applicable to induction motors driving trains where the current is generated on the train. The intermittent or fluctuating current may be obtained by interrupting the exciting-circuit of the alternator b, Fig. 1, or by varying resistance in series with the armature f or field of the exciter. The interrupter or rheostat h may be operated by band, or by a motor k, the speed of which may be varied. The brake o<1> for the primary member of the motor may be interlocked with the vehicle brake o, the brakes being operated by a lever r so arranged that, normally, the weight of the handle s, or a spring, or other convenient means, keeps the brake o<1> applied while the brake o is released. Upon lifting the handle, the brake o<1> is released, while a further elevation of the handle applies the brake o. The motor may be further controlled by rotating the primary member as described in Specification No. 8851, A.D. 1907. In this case, solenoids t, u, Figs. 3 and 4, may be included in the circuits of the primaries q, u<3>, respectively, to operate the brakes. When the two solenoids are energized, both brakes are released. The regulating-motor may be supplied with current from an auxiliary generator, which may also be used to supply to the main motor, when the regulating motor is idle, a current of lower periodicity than that given by the main generator. The speed of the auxiliary generator may be varied to supply a current of variable periodicity.

Title: Improvements in and relating to Compressed Air Brakes
Inventor: DOYEN JOSEPH
Filed: 1908-06-29
Granted: 1909-01-14
Abstract: 13,771. Doyen, J. June 29. Brakes.-In fluid-pressure brakes, a second piston is placed between the train-pipe and the main valve piston of an ordinary triple valve, for preventing losses of air from the auxiliary reservoir through the feed grooves of the main piston before the latter close in an application of the brakes. The second piston controls a slide valve for venting the train-pipe in emergency applications. Fig. 1 shows the slide valve piston 2 of an ordinary Westinghouse triple valve in running position. Air is supplied from the train-pipe 3, through the passage 5 to the lower side of the second piston 6, whence it passes to the chamber 17 and to the auxiliary reservoir, through passages 24, 21, Fig. 5, controlled by a check valve 22. The piston 6, Fig. 1, abuts against a weak spring 7 carried by a cage 8 operating a slide valve 10, and supported by a strong spring 9. The valve 10 controls a passage 40 leading through a loaded valve 11 to an exhaust port 13. The chamber 17 communicates through passages 15, 16 with a supplementary reservoir, serving as an enlargement of the chamber 17, and with one side of a valve 19, Fig. 5, the other side of which is acted on by the train-pipe pressure and by a spring 20. In operation, when a slight reduction of train-pipe pressure takes place, the parts of the valve remain in the position shown in Fig. 1 until the reduction of pressure on the underside of the piston 6 causes the spring 7 to be compressed, when the chamber 17 is open to the train-pipe through a cavity 14. The reduction of pressure in this chamber takes place rapidly, and the feed grooves to the auxiliary reservoir are quickly closed, preventing any escape of air. When the train-pipe pressure is reduced for an emergency application, the piston 6 moves downwards past the cavity 14 and compresses the spring 9. The reduction of pressure in the chamber 17 due to the movement of the piston 6 is only sufficient to cause a slight movement of the piston 2, owing to the reservoir connected thereto, and consequently the brakes are only partly applied. The movement of the piston 6 and slide valve 10 uncovers the port 40, venting the train-pipe to atmosphere. This continues along the train and opens an accelerating- valve on the rear coach. The train-pipe pressure is now so reduced that the pressure in the chamber 17 opens the valve 19, venting the chamber to the train-pipe and causing the piston 2 to fall to apply the brakes fully. Since the train-pipe is vented at the front through the driver's valve and at the rear through the accelerating-valve, this application of the brakes will take place simultaneously on the front and rear coaches. The reduction in the train-pipe pressure due to the valves 11 can be regulated by dispensing with the valves 11, and connecting the port 40 to a pipe 28, Fig. 6, leading to a chamber which is normally connected to an exhaust port 27 through a cavity 26 in a slide valve 25 replacing the valve 10.
