Title: Improvements in Multicylinder Engines.
Inventor: PAYNE-GALLWEY EDWIN JOHN
Filed: 1901-07-22
Granted: 1902-07-03
Abstract: 14,911. Payne-Gallwey, E. J., [Whitehead, R.]. July 22. Radial-cylinder engines.-Relates to multi-cylinder engines having single-acting cylinders distributed equally round a central crank chamber, and more particularly to compressed-air engines used for propelling automobile torpedoes. In Fig. 1, one third or unit of the engine is shown in section through the cylinder and piston, another is shown in section through the valve chamber, and another in section partly through the cylinder and partly through the valve chamber. In order to diminish side thrust on the pistons during the working strokes, the cylinders are disposed so that their axes a a, b b, c c form tangents to a circle f, which is concentric with the crank shaft. In engines in which the head of the piston-rod serves as an oscillating slide valve, this disposition of the cylinders enables a wider opening of the exhaust port and a more rapid exhaust to be obtained. The valve chambers are disposed so that their axes a<1> a', b<1> b<1>, c' c<1> are strictly radial to the crank shaft.

Patent GB-190118027-A (GB)
Title: Improvements in Dynamo Electric Machines and Motors
Inventor: GUY GEORGES
Filed: 1901-09-09
Granted: 1902-01-16
Abstract: 18,027. Guy, G. Sept. 9. Converting alternating and direct currents; transformers.-Relates to machines of the inductor type, capable of operating as continuous or alternating-current transformers. The construction of the machine is such that high voltages and frequencies can be obtained at a low speed. The rotating part has the form of a toothed cylinder b, built up of iron discs, while the fixed part consists of a hollow cylinder c, also built up of iron discs and having its internal surface divided so as to form a number of poles, each of which is toothed as shown in Fig. 2. Adjacent poles have their teeth in different positions relatively to those of the rotating part. In the spaces between the poles are arranged-(1) an inducing-winding d, e, (2) an induced winding composed of two coils k, l for low-tension currents, and (3) an induced winding composed of two coils m, n for high-tension currents. The coils k, l are connected together in series, and the ends and middle point of the winding thus formed are connected to the three brushes of a commutator driven by a small synchronous motor, Figs. 7 and 9, whereby current is supplied to the inducing-winding d, e. In the case of a continuous-current machine, the high-tension coils m, n are similarly connected to a commutator driven by the same synchronous motor. A suitable form of commutator is composed of four cross-connected segments, the two pairs of segments so formed being connected to two collecting- rings. By the use of a separate motor for driving the commutators, the latter are automatically regulated so as to give the minimum of sparking. All the sparking may be caused to take place at the low-tension commutator by narrowing the segments or brushes of the high-tension commutator. A regulating effect is obtained by connecting to the inducing and induced windings on the stationary part of the machine supplementary windings which are short-circuited on themselves. In a modified construction, a number of toothed discs mounted on a vertical shaft are arranged to rotate between a corresponding number of fixed discs.

Title: Improvements in or relating to a Method of and Means for Propelling Ships and the like.
Inventor: PONS PIERRE
Filed: 1902-02-05
Granted: 1903-01-22
Abstract: 2945. Pons, P. Feb. 5. Propelling by water jets; screw propellers.-In vessels propelled by turbine motors or hydraulic engines, the head of water for driving the turbine or turbines T is supplied by a tube or tubes A having their inlets below the water line. The water is discharged at the stern of the vessel by the pipes S, P, E, the discharge being facilitated by the pressure of the head of water entering through the pipe C, by the partial vacuum created at the stern by the wash, and by the depression of the trail water through the action of the propeller, which is driven from the motors T by belts or gearing K. The pressure on the water discharged at E may be further increased by means of a pump, archimedean screw, or steam injector, or by steam-pressure or pneumatic apparatus. In the preferred pneumatic apparatus, the motors T drive the pistonrod of an air-compressing cylinder, forcing air under pressure into a closed water tank, and thence into an opening in the ejecting-pipe. The discharge may also be assisted by an openended pipe passing from the bow to the stern of the vessel. It is stated that the starting of the ship may be facilitated by providing either a flywheel for accumulating speed, or a " donkey- " engine " or steam motor, the latter being then employed instead of the pneumatic apparatus, to assist the discharge. To enable the vessel to move astern, a separate motor having its water inlet at the stern and its outlet at the bow is provided.
