'hpplicstion filedi ovembsr To all whom it my concern:- v.

Be it known that 1', JOSEPH W. 'llnrnrns,

of Syracuse, inth-e county of Qnonduga, in the State of New York, have invented new and useful Improvements in Liquid Hydrocarbon Engines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description. v

This invention relates to certain improve ments in liquid hydro-carbon engines of the reeiprocetory piston type'having a balance heel provided with suitable buckets and adapted to be 0 eraied by the exhaust from the explosion c amber of the engine .cs an auxiliary motor for the purpose ofntiiizing practically the entire expensive force oi the exploded gases before-final liberation to stinosphere. i The specific invention li cs more particularly 1n the constr notion and arrangement of the blades orbuckets against which the 'impelling fluid is projected, a d also in the relative arrangement of the ihlet end exhsust so as to relieve, ss'far as practicable back pressure or retarding action of the fluid in its transit. frointhe inlet to the exhaust of the auxiliary motor. I My objects, therefore, are first, to provide any steam or vapor engine with an auxiliary motor actuated solely W the exhaust of said vapor engine; second construct the buckets or blades in such dinner as to deflect the impelling fluid transversely across the face of the runner to which the buckets are attached, and to enter the impelling fluid at one side of the casingsubstuntiell'y tangential to the periphery of t which the buckets are secured and to locate the exhaust in the opposite side of the casing directly opposite the inlet, so that ss soon as the iinpelling fluid strikes the bottoms of the buckets or blades successively, it is immediately deflected transversely through the exhaust Without being allowed to travel any appreciable distance circuinferentislly of the runner.

f Other objectsri-nd uses will appear in the following description.

In order to clearly demonstrate the procticability and utility of my improved motor. I have shown it in Figs. 1 and 2, as operated by the exhaust from a gas engine, while in Figs; 8 to 5 inclusive, I have shown the some motor as adapted for individual operation independently of any other motor and capable of being operated by Water, steam or any other expansive fluid. This motor comprises essentially an outer case l', a runner or rotary element -2- carrying upon its periphery aseries of buckets -3- of special construction hereinafter described.

l he casing preferably consists of a circular hollow central section or ring and opposite end heads -5- which are secured to the opposite ends of the rings 4 by suitable clumping bolts 6 The interior dimensions of the casing are just sui'iiciently large to receive the runner -2- and its buckets or blades 3-, the opposite ends of said casing being formed with annular flanges 7, preferably within the periphery of the runner -2- Which has on easy running fit Withinthe casing,

and around the flange 7-.

One of the end heads 5 is with an inlet-9- which is connected by a pipe 10- to the exhaust, as ll, of a gas engine -12' having an inlet 13-. The inlet -9 is disposed at an ungic with the axisof the casing and runner --2--somc distance therefrom sons to discharge nearly tangential to, but across the face of said runner and against the blades or buckets -3 to impart rotary motion to the runner. The opposite end'head -5- is provided with an exhaust port -8 directly opposite the inlet and therefore, in line with the opposite sides of the buckets 3- which are disposed in a substuntiall y horizontal plane or parallel with the axis, while the provided an angle with the axis, and nearly tangential to the plane of rotation ofthe buckets so Fnatihe impelling fluid is driven obliquely ,zigninst the blades or buckets as" they are successively presented to the inlet, suchiimpelling'iinid being defl cted by said buckets shown an automatic cut-oil" valve in the inlet is disposed in an oblique position or at i transversely across the face of the runner I strii'zted vertically,

and directly through the exhaust port. The inner end of the inlet 9 is conbut broadened radially,

thereby producing afan-shapej opening for 'dischargin "a sheet of the exploded gases of substantial y 1 blades againstthe latter for lncrasing'the forceof the impact and cans.

the same radial width of the the purpose of ing the broad jet to be confined more closely within comparatively narrow circumferenti'al limits at its initial entrance into the runner chamber.

1' preferably provide the runner with two "diametrically opposite sets or series of buckset of blades is merely used to counter balance theother set and are so arranged that the first bucket of the series is registered with the inlet port -9-'at about the same time that the exhaust port -1 1 of the gas engine is open a sufficient numbenof buck- "they ets being provided and so arranged that will all pass the inlet While the exhaust port of the vapor engine is open, the piston of the vapor engines serving to cut off the exhaust, and therefore, cuts off the supply of the impellirig fluid to the motor as soon as the last bucket of the serieshas passed the inlet -9 In this case, where the gas engine and motor are combined, as shown in F 1 and 2, the piston acts as a cut oil valve, but it is preferably provided with a rotary valve- -16-' having diametrically opppsite ports -'17, said valve being located in a suitable valve case 18 forming a part of the supply pipe -l0-. best seen in Figs. '5 and 6. In thisinstauce, both sets of buckets are in action, and thc'n'iovcment ot' the valve -l(i is synchronized with the movement of the runner by connecting the runner shaft to the rotary valve through the .medium of suitable gears -20-- of substanfluid is out ch.

tially the same pitch. This valve -l(S* is actuated so as to open the ports -17 at the same time that the buckets of each set 'or' series are presented to the inlet 9 and are closed soon as the last bucket of each series passes said inlet, the,;runner 2- serving as a balance Wheel to carry the buck c ts through part of the revolution oi" the runner when the simply ol the impcllinn As best seen in Figs. 3 and 4, the ends of the bucket nearest the inlet -1), are open, while the opposite ends of said buckets nearacts against the rear same shaft with the piston more easily deflect the steam from said buckets to the exhaust without materially retarding the action of the runner. In words, by deflecting the ends of the buckets near the exhaust rearwardly I avoid in a measure, the reaction or recoil of the exhaust gases at the exhaust port, theiront faces of the deflected ends of the buckets serving to expel the exhaust. gases, while the recoil, or reaction of the exhaust gases from said front faces of the deflected ends of the buckets reiuceof the preceding bucket. thereby giving the runner additional impetus.

In order to prevent. excessive expansion of The exhaust gases between the buckets, l pro vide each with a substantially central trans verse partition l2, as best seen in Fig. 4, dividing cachbucket into two corupartments with constricted passage beneath each partition connecting said romparlments, to allow said gases to escape from those nearest the inlet to those nearest the outlet, and

thence into the exhaust S.-

It is desirable to mutlle the sudden dis: charge of the runner impelling fluid from the. exhaust, and for this purpose I provide said exhaust with an outlet conduit 2 l-- divided into two branches 25- leading in opposite directions from the main exhaust pipe -2aland terminating in a single conduit 26-- where the force of the impact of the exhaust gases passing through both branches is neutralized by contact with each other so that the exhaust gases finally discharge at nearly atmospheric pressure.

The operation of my invention will now be readily understood upon reference to the foregoing description and the accompanying drawing. and it will he observed that the specific features ot invention consist first, in (JODl'lGCtlllQ the inlet oi the motor directly to the exhaust of a piston engine; second, mounting" the runner of the motor upon the engine, and timing its movement so that the buckets are presented to the inlet while the exhaust port of the piston engine is open'; third, constructing each bucket so that its end nearest the inlet. is open.'whilc its end nearest the exhaust is deflected rearwardly; fourth, providing the buckets with transverse partitions terminating a short distance from the bottom of the hucltct so as to leave a. comparatively narrow or constricted passage between the buckets from the inlet to the exhaust ports, and fifth. locating the inlet. and exhaust ports directly opposite each other in the opposite heads or ends of the casing, and sixth, diverting the discharge of the exhaust through opposed branches which n 0 h merge into a single conduit. so that. the no- 134.
