HYIbROOARBON GAS 'rImnINE.

To all whom it may concern:

Be it known that I, Isaac N. REED, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented new and useful Improvements in Hydrocarbon Gas Turbines, of which the following is a specification.

This invention relates toa rotary engine or turbine of that type in which'the motive fluid consists of an exploded charge of carbureted hydro-carbon. l

The invention has for one of its objects to improve and simplify the construction and operation of prime movers of this character so as to be comparatively slmple and inexpensive to manufacture, reliable and efficient in use, and composed of comparatively few parts.

Another object of the invention is the provision of a novel arran ement of rotary sta tionhry buckets and ischarge nozzles, in combination with means for producing a motive fluid "of high pressure to be discharged through the nozzles to the buckets'f With these objects in view and others, as-

will appear as the description proceeds,'the invention. comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto. Inthe accom anying drawings, which iiodiment of the invention,

Figure 1 is an end view of the machine.

Fig. 2 is a vertical section taken trans versely to the axis of rotation. Fig. 3 is a vertical section on line 33, Fig. 2. Fig. 4 is a plan view. Fig. 5 is a detail sectional view of the nozzles showing their relation to the buckets.

Similar reference characters are employed to designate corresponding parts throughout the views.

Referring to the drawings, A designates the turbine, and B, the fluid-producing device mounted on the turbine and operatively related thereto 'so that the nozzles will re" ceive motive fluid at high ressure.

The turbine A consists o a casing 1 of any approved construction, throu h which passes a central shaft, the shaft being journaled in bearings 3 at the heads 4; of the casing. Arran ed in the casing and mounted on the'shaft 1s a wheel of the double axial Specification of Letters Patent.

flow t pe, said wheel consisting of two sets "of dis .s 'r and Z located, respectively, to the right and left of, the central transverse plane of the casing, there being shown two disks in each set, but it is to be understoodthat any desired number of bucket-carrying elements or disks may be provided/ On the periphery of each disk are radial buckets 5 of proper curvature, and between adjacent rotating rows of buckets are stationary intermediate buckets 6 that are curved oppositely to the wheel or moving buckets so as to reverse the direction of fiow of the motive fluid in its passage from one set of moving buckets to the next adjacent set. The casing is provided with an internal projection or web 7 that is located in the ccntral-transverse lane and disposed between the inner mcst' iskson the shaft 2, and in this Web are oppositely-inclined discharging devices or nozzles 8 that are disposedat the proper angle with respect to the wheel buckets, the said nozzles being connected with the common throat or passage 9 through which the;

motive fluid or exploded gases pass to the nozzles. The exploded fluid is discharged intermittently, and being 'ofhi'gh temperature, it is desirable to increase the volume.

of the motive fluid by discharging water or other fluid into the throat 9 at the time the fired gases pass therethrough, and for this urpose a conduit or passage 10 is formed in the wall'of the casing to lead into the throatQ, the said conduit being connected with a suitable device (not shown) for discharging'a definite amount of water at the proper interval.

" The fluid-producing device B consists of a 'cylinder'll mounted on the casing or 10- cat'ed in any other suitable point, and in this cylinder 'reciprocates a compression piston 12 that is connected with the pitman 13- which is operated by an eccentric 14, said eccentric being arranged on a shaft 15 that has a wheel 16 connected by a belt or sprocket chain 17 with a wheel or sprocket 18 on the main shaft 2. The eccentric shaft is jou-rnaled in bearings 19.formed on the turbine casing, and on this shaft is a hand wheel-20 whereby the eccentric shaft can be turned for operating the compressor or pump piston 12. The cylinder connected by a pipe '21 with a carburetor or other source of explosive mixture so that when the piston moves forwardly, a charge will be Patented Mar. 26,1912.

l cation is interrupted b y the piston or {01- drawn into the cylinder and subsequently com ressed on the inward or rear stroke.

In t ahead 22 of the cylinder isYormed an explosion chamber 23that is connected with the cylinderthrough a port orpassa e 24, the said passage being normally close by a puppet valve 25 which has a stem 26 passing outwardly through a plug 27, there being a spring 28 on the other end of the stem that operates to automatically close the valve between the cylinder and combustion chamadapted to communicate with the throat. of the nozzles immediately after-"the dompressed explosive charge in the chamber 23 1s ignited, but at other times the communilower 29 that moves across thechainber 23 and engages the seat 30 at the receiving end' of the nozzle throat 9.' The'piston valve'29 I'm provided with a stem 31 which is con- 'nected at 32, with a lever or rocker 33, the

. latter being fulcrumed at 34 in a bearing 35 "on the head of the cylinder. Att'he.head

{at the cylinder is a transverseshaft 26 mounted in bearings 37, andon'this shaft shaft 1 5 'is a cam 38 that wipes on the lever 33 in -such'a manner that the piston valve 29"is moved to open position at the' properin.-

valve 29 being closed at'this t-iiii The gases in the chamber 23 are now ignited by a spark plug Mo -equivalent device, and the valve 29 opens to permit theexploded gases tov pass. 'to' the turbine," the force of explosion insuring the closing of thavalve 425. While the exploded gases passthrough.

the nozzle, is'injected into magm so as vto be converted into stezjun toinc'rease thevolume of the rii'otive 'fluid., ,Whi1e,'thefm o-; tive fluid, is discharging to the turbine, the

piston 12 moves outwardlyi flto draw .in

another charge ofmixture so that thecycle This combustion chamber 23' just described will be repeated and in this way continuous rotation of the turbine Wheel maintained. f.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled inthe art to which the invention appertains, and while I have described theprinciple of operation of the invention, together with the apparatus which I now consider to be the best embodiment thereof, I desire to have it understood that the apparatus shown is merely illustrative, and that such changes may be made claims appended hereto.

, Having thus described the invention, what I claim as new, is

1. The combination of a turbine including sets of revolving buckets, and oppositely discharging nozzles dis oscd between the said sets for delivering aid to both simultaneously, said nozzles having a common throat, with a combustion chamber adjacent the "said throat, a. valve for closing the when desired as are within the scope of the I throat for interrupting communication betfweenfthe' chamber and nozzles, meansfor delivering a compressed charge of explosive mixture to the chamber, means for guiding the-mixture in the chamben'and means for the ignition of the harge'. '2. The combination of a turbine including sets'ofrevol'ving buckets, and oppositely discharging nozzles disposed between the opening-the saidhvalve ,in-. timed relation to a said sets for delivering fluid to both simultaneo'usly', said nozzles having a common throat, with a combustion chamber adjacent the said throat, a valve for closing the throat for interrupting communication between'the chamber and nozzles, means for delivering-a compressed charge of explosive .mixtureto the chamber, means for vguiding the mixture in the chamber, means for opening the said valve in" timed relationtg the ignition of the charge, and means through which liquid is delivered to the throat/of the nozzles simultaneously ,-.with the passage of the fired gases therethrough.
