To all whom it may concern:

Be it known that I, CHAnLEs W. MeGoNreLE, a citizen of the United States, residing at North Yakima, in the county of Yakima and Statel of Washington, have invented a new 'and .useful Engine. of which the following is a specification. v v

This invention relates to apparatusfor the production of gases under pressure to be utilized for motive power, and has for its principal obect to provide' an apparatus in the nature of an internal combustion engine in which gas under pressure and steam may-be generated and utilized directly .in the operation of a rotary or turbine engine. f .A further object of the invention is to provide an apparatus which will operate steadily and without the noise. and shock incident to ordinary engines [of the explosive type. e l

With these and other objects in view, as will more fully hereinafter appear, the invention consists in cerparts, hereinafter fully describedJ illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the structure vmay be made without departing from the spirit or sacrificing any ofthe advantages of the invention. l

In the accompanying drawings:-Figure l is a side elevation, partly in section, of an apparatus constructed in accordance with the invention. Fig. 2 is a transverse sectional view of the engine proper on the line 2-2 of Fig. 1 Fig. 3 is a vertical section of the enginel on4 the line 3-3 of Fig. 2. Fig. 4 is a detail sectional view of one of the thermostatically actuated valves.

Similar numerals of reference are employed to indi' cate corresponding parts throughout the several figures of the drawings. l

. In carrying out the invention, a comparatively large cylinder 10 is provided at one of its sides with a bearing opening for the reception of a shaft 11., and to the shaft is secured a revoluble piston 12, that is provided witha plurality of vanes or buckets 13 which may bev curved, as shown in Fig. 2. 'i Extending within the annular row of blades or vanes is an annular chest '14 that is rigidly secured to the stationary side wall or head of the'cyl` indcr, and this chest is provided with a plurality of ports 15, through which the actuating fluid is directed l against the vanes 13 for the purpose of revolving the piston.

Secured to the cylinder and in direct communication with the annular chest 14 is a generating chamber 20 that is preferably in the form of an elongated cylinder, t the longitudinal axis of which is coincident with the axis o f the shaft. This cylinder is formed of any suiti able material, andin practice will be jacketed in the same manner as the cylinder of an ordinary internal combustion engine.

Extending into the cylinder is a series of burners 22 which may be .connected to any suitable source of gas supply, each burner having a suitable regulatingvalve 23. The air to support combustion is admitted through a pipe 24 preferably from a suitable compressed air reservoir, and said pipe4 24 is connected to a helically wound perforated coil 25, so that the air may become highly heated within the coil and then discharged in minute jets all around the burners, the quantity of air being greatly in excess of that required to support coinbustion, `and such air becoming highly heated and intermingling with the products'of combustion to form a gasunder ay pressure sufficient to operate the engine.

In order to reduce the temperature within the gen- I erating chamber to some extent, and to add to the yolume and pressure of the operating fluid, a Water supply nozzle 25 is introduced into the chamber at a point between the burners and the engine', and water is forced under pressure through this chamber, the water being instantly llashed into steam, which, beingintermingled with the air and gases, will add materially to the volume and pressure of the actuating fluid.

The air pipe 24is provided with a valve 28 that is under the control of 'a thermostat 29, so that when the heat becomes excessive, the valve may be closed to a greater or less extent by the operation of thethermostat and in similar manner the water jet supply pipe has a thermostatieally operated valve 30 for governing the supply of water. '4

Fig. 4 illustrates one form of thermostaticallyactuated valve for controlling the Water or air supplies. The casing 30 is provided with a partition 31 having a deuble conical `seat 32, one forv receiving the manually actuated valve 33 and the other the thermostatically actuated valve 34. The y'valve 34 is attached to a spring pressed piston 35 working in the cylinder 36 of the casing 30. This' piston is actuated by a column of mercury contained in the tubular thermostat 29, and as the mercury expands under the increased temperature of the air in the pressure chamber, the valve 34 is caused to close so that thesupply of air or water, as i I the case may be, is cut off. As soon as the temperature falls to a predetermined limit, the valve 3 4 will open to restore the supply of air or water. When it is desireii to positively cut off the supply, Vthe manually actuated valve 33 is closed.

In order to ignite the gas an ordinary form ofelectric v sparker'40 may be used as indicated in Fig. l. y f W ith an apparatus constructed in accordancev with this invention, steady and uniform power may be attained at comparatively small expense, and the operationmay be carried on without the noise and jar incident to the operation of ordinary engines oi the explosive type.

l I clailnzl 1. The combination with an engine, of a. pressure chamber in permanent communication therewith, a perforated conduit arranged helic'aily within the chamber, a plurality of burners disposed within the chamber in proximity to -the conduit to receive air therefrom for supporting coml bustion,l

means for supplying air to the conduit in excess of the amount required to support combustion to be heated by the burners, and an automatic meanssensitive to the temperature of the airwit'hin the chamber for controlling the air supply.

2. In combination, a turbine engine, a iuid pressure generatingchamber in direct communication therewith, a

i i i v\ i i gns burner in the chamber, a perforated air 'pipe coiled within the chamber. and means for forcing air under pres sure through said pipe.

3. The combination with a turbine engine, of a pressure chamber in direct communication therewith, a perforated tube arranged in a helical coil within the chamber, means for forcing air under pressure through said tube, a gas and expand the air, and a water jet pipe extending within the chamber at a point in advance of the burner.

lntestimony that I claim the foregoing as my own, i have hereto axillxed my signature in the presence of two witnesses.
