Patent GB-190323352-A (GB)
Title: Improvements relating to Elastic-fluid Turbines.
Filed: 1903-10-28
Granted: 1904-10-27
Abstract: 23,352. Warwick Machinery Co., [General Electric Co.]. Oct. 28. Steam &c. turbines.-The nozzles of an elasticfluid turbine of the jet kind are arranged in groups and provided with valves which are closed or opened automatically according to the load on the engine by a cam cylinder or its equivalent, a lost motion connection being provided between the governor and cam cylinder. A jet turbine of the vertical shaft type is shown in Fig. 1. At the upper end of the shaft is a governor which actuates the cylinder 8 by the rod 9. In Fig. 2 is shown a nozzle valve actuated by a piston under the control of an auxiliary valve operated by the camcylinder 8. When the auxiliary valve is closed, the piston exhaust is open so that the nozzle valve is raised from its seat due to the unbalanced pressures on the piston. As shown in Figs. 3 and 4, the cam cylinders are mounted on the shafts 20, 37 which are operated through the medium of the rack 28 and mutilated pinions 27, 34, constructed so as to allow lost motion. By this arrangement, one or more valves may be actuated in one group, and then one or more iu a second group, and so on. The springs of the governor which operates the rack may be adjusted by an electric motor controlled from a distance. In Fig. 7 is shown a modification of the previous arrangement. The end of the cam cylinder is provided with a mutilated gear 44 which engages with teeth on the rod 42. On the left-hand side of the governor is a bell-crank lever 46 which moves outwards with increase of speed. On the lower end is a roller which runs in the loop 48, Fig. 9. Mounted on the front of the lever is a spring-pressed latch 50 which enters a notch 51 in the loop 48. A stationary piece 52 raises the latch out of engagement with the notch when the lever moves inwardly. There is thus a lost motion device between the governor and cam cylinder 53. In a further modification each of the cam cylinders is actuated by a device such as shown in Fig. 9. In Fig. 10 is shown the relative positions of the latches and notches in the case of an engine with three cam cylinders. For the purpose of illustration, the lower ends of the bell-crank levers are shown as being united by a frame 63. (For Figs. 7, 9, & 10 see next page.)

Title: Improved Means for Obtaining Motive Power by the Action of a Jet of Steam or other Gases.
Inventor: VOGT ADOLF
Filed: 1904-11-30
Granted: 1906-02-28
Abstract: 26,086. Vogt, A. Nov. 30. Impact-wheels.-A current of water of a comparatively low velocity is produced by steam or gas jets 1, surrounded by perforated plates 5 through which the water passes. The particles of steam impinge against the various layers of water drops, which increase in velocity as their distance from the nozzles increases, and consequently do not lose their energy by impinging against each other as they do in the converging tube of an injector. The tube 3 gradually diverges and terminates in a curved trough 4, opens on its concave side, in which the water becomes a compact jet under the inflence of centrifugal action and the gases escape therefrom. When used with a Pelton wheel, a guard 6 prevents spray from rebounding on to the jet.
