Smith and Joseph Isaac, Sault Sainte Marie, Mich.. Application May 29, 194.5, Serial No. 596,454 4 Claims. (Cl. 60-41) 1 2 This invention relates to turbines, and more particularly, to internal combustion gasoline tur bines. A main object of the invention is to provide a novel and improved gasoline turbine wherein the fuel mixture is compressed prior to admission into the ñring `chamber and fed under pressure into the firing chamber where it strikes the ro tary blades causing steady rotation and nre over setting of a distributor point 23 of a distributor 22 driven from shaft 6, distributor point 23 being connected to spark plug 25 by a cable 24. The cooling system comprises a fan I0 mounted on the shaft of a generator I I, fan I0 being con nected by an air duct 9 to a peripheral air cham ber 8 provided in the turbine housing 4. Gener ator II carries on its shaft a gear I2 which meshes with an oil pump gear I3 which in turn meshes with a gear I4 carried on shaft 6. The lap. A further object of the invention is to provide an improved gasoline turbine utilizing pre~compression of the fuel mixture, and wherein im proved regulating means for controlling the pres sure of the compressed fuel mixture is employed. Other objects and advantages of the invention will appear from the following description and claims, and from the accompanying drawings, wherein: p Figure l is a longitudinal cross-sectional view taken on line I-I of Figure 2 of an embodiment of a gasoline turbine in accordance with this in vention. ` Figure 2 is a vertical cross-sectional view taken on line 2_2 of Figure 1. Figure 3 is a detail cross-sectional view of an exhaust pipe fitting taken on line 3_3 of Fig gear train thus drives generator I I and fan I0. Provided adjacent housing 4 is a housing 50 through which shaft 6 passes. Journaled in housing 50 is a crankshaft I1 carrying a gear VI5 adapted to be connected thereto for rotation of `the crankshaft by a clutch I6. Gear I5 meshes with gear I4. Crankshaft I1 is provided with a crank provided with a connecting rod I8 which is pivotally connected to a piston rod 5I passing 20 through a packing nut 20 into a cylinder 52, said piston rod being provided with la piston I9. A plate 53 is provided, forming the lower wall of cylinderl 52. An air intake valve 42 is provided in said plate 53, said intake valve being- con-` 25 nected to the atmosphere by a conduit 54.A An air outlet valve 4I is provided in plate 53, said outlet valve being connected by a conduit 3| to ure 2. Figure 4 is a detail view of the valve structure employed in the air compression cylinder of the gasoline turbine of Figure 1. Referring to the drawings, 6 designates a m0 ltor shaft which is adapted to be driven by a turbine wheel 2 contained within a housing 4, said shaft '6 being rotatively supported with respect i to housing 4 by a pair of bearings 3, 3, the out side bearing being provided with a protecting cover plate 5. Formed in housing 4 are a plurality of ñring chambers I, each chamber being provided with an intake slide valve 1 and a spark plug 25 for exploding the fuel mixture furnished to cham ber i. Appropriately peripherally spaced with respect to each firing chamber is an exhaust port 48 and an exhaust pipe for exhausting the ex ploded mixture after delivery of its power stroke to the blades of the turbine wheel 2, the exhaust pipes being connected to a conventional exhaust manifold. The timing of valve 1 is controlled by an 4ap- ‘ propriate cam 49 which is mounted on shaft 6, said cam 49 actuating slide valve 1 by contact with a follower member carried by said slide valve. 'I‘he timing of the spark at each spark plug 25 is controlled in a conventional manner bythe `_ an intake valve 55 provided in a compression Y tank 31. The reciprocation of piston I9 in Vcyl inder 52 will thus be effective to pump air into i tank 31. Crankshaft I1 is provided with a first cam 38 which reciprocates a slide valve 49, and a second cam 39 which reciprocates a poppet valve 21. A fuel tank 4-5 furnishes fuel through a conduit 46 to a carburetor 30 from which the fuel `is deliv ered through slide valve 49 to a chamber 56 above piston I9. The fuel is pumped by piston I9 into a compression head 28 from which it is delivered The cams 38 and 39 are arranged with respect to the crank or crankshaft I'I so that valve 21 opens and valve 40 closes While ` to tank 31. piston I9 is delivering its power stroke, while said valve 40 is opened and valve 21 is closed during the return stroke of piston I9. Sufficient suc tion is developed on the return stroke of piston I9 to draw a substantial charge of fuel into cham ber 56. The fuel is pumped from compression head 28 to compression tank 31 either through a prim ing conduit 51 and a first spring-biased priming valve 35, or through a main fuel conduit 29 and a second spring-biased main valve 5B to an in take valve 59. Valve 35 is arranged to admit fuel 1111.50 tank 31 until a normal working pressure is 2,409,909 3 4 v developed therein, for example, 35 pounds per square inch, whereupon valve 35 is closed. tation of the turbine wheel may be varied over Valve a substantial range. l58 comprises a cylinder containing a sleeve 33 slida-bly positioned in an outlet port tt, the upper end of sleeve 33 being normally in abutment with a seat provided at the top of said cylinder to close off said sleeve.
