. To all whom it may concern:

Be it known thatLLYMA E. WARREN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain newhndguseful Improvements in Apparatus for Generating and Transmitting Power, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertcins to anake and use the same.

This invention relates to a fluid operated power unit and with respect to its more specific features, to a machine assemblage ofv the type described, comprising a rotary reaction engine.

One of the objects of the invention is to provide a device of-the class described which will be'compact and may be mounted in a small s ace. g

- Anot ier object is to provide a device of the kind described whose moving parts shall hfii ubstantiallybalanced.

other object of the invention is to provide a practicaland eflicient device of the class described which shall have a maximum etiiciency and ease of operation. 4

Another object is to provide a device of the class described which shall be simple and cheap in construction and inexpensive to operate.

Another object is to provide a practical and etiicient engine whose parts may be .readily assembled and disassembled.

Other objects will be in part obvious and in part hereinafter pointed out. v

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the drawin wherein is shown one of the various possi le embodiments of the invention, Figure 1 shows a plan view thereof, certain parts being-omitted for thesake of clearness; Fig. 2 represents a cross section on the line w-w of Fig. '1 showing a portion of the casing broken away and revealing the buckets-therein; Fig. 3 is across section on the line'-wae of Fig. 1, omitting'certiiin parts for the sake of cleurness; Fig. 4'. is a diagrammatic end elevation of the machine showing the relation of the various parts. Fig. 5 is a detailed longitudinal cross's chereinafter.

Similar reference numerals indicate similar parts throughout the various views of the drawings.

Referring now more specifically to the drawings, we find in Figs. 1 to 4, a generally oblong rectangular frame-work 1, provided with side walls 2 and 3, end Walls 4 and 5, and a top 6. Supported at either end thereof in hearings in the side walls 2 and 3 are transverse shafts 7 and 8. The

transverse shafts are substantially parallel .work but also serves to prevent the dropping of articles into the gear mechanism and ports from above and. also keeps out the dust. The shafts 7 and 8 support two sets of reaction engines. The shaft 7 supports at either end thereof at a point outside the walls of the frame-work 1. reaction engines 9 and 10. The shaft 8 supports at either end thereof at a point beyondthe wall of the frame-work, reaction engines L1 and 12. Each of the reaction engines is provided with a plurality of conduits or arms, which will be described more fully The shaft 8 is shorter than the shaft 7 in the embodiment shown,

whereby the conduits or arms of engine 11' mounted on the end of shaft 8'will clear on the end of shaft 7. The sameprovision is made in connection with engines 1.2 and the conduits or arms of engine 9'mounted only supports the shafts 7 and 8 and engines thereon, but also suspends the casings surrounding them, as more clearly shown in Fig. Upon each of the shafts 7 and 8,

"and intermediate the engines mounted on either end thereof, is a worm wheel 15 which is adapted to rotate with the shaft and to coact with a worm gear 16 below the shaft to transmit power from the engines. The worm gears are mounted-on the main shaft 17 which passes through each of the gears and which is supported in'bearings 18 and 19 which are situated on ends 4 and 5, respectively, of the supporting frame-work 1,

At one end of the shaft, pulleys 2O may be conveniently arranged for transmission of power. It is to be noted that any other powertransmission means might be used in this connection. At the end. of the shaft opposite the pulleys is arranged a pump 21' which is adapted to be. operated from the main shaft by means of an eccentric strap 22 which passes there-around and isadapted to be connected to the pumping cylinder by means of a rod 23. It will be noted that the worm gear mechanism and the transmis-' sion members in general are supported by the frame-work 1.

As shown more clearly in Fig. 4, the engines are adapted to be supplied with steam from a flasl1boiler 24 which is mounted longitudinally of the frame-work 1 upon suitable supports 25,.being held in position between the exhaust casings of the four, en-

gines shown and generally below the uppermost port of the casings. Beneath the boiler is-provided a suitable torch 26 which is also mounted upon the frame-work. At a point below the lowermost point of the gear mechanism and generally below the casings 14 is a reservoir 27 which is connected with piping 28 adapted to transmit the products of condensation from the casings thereto, and also piping 29 leading to the pump. The reservoir 27 acts as a supply reservoir for the boiler and the water pumped therethrough V is forced through the pipe 30 by the pump 21 into the boiler. Suitable pipes 81 connect the boiler with the reaction engines. it will thus be seen that the framework 1 inter between the engines and casings supports all the parts of the machine, and it is to be noted that the structure thus produced is very compact in form and may be placed in various positions, upon, for instance, automobiles and other vchicles,-0r in cramped places in motor boats and the like with zfrent facility", at the same lime the parts may be readily inspected, and gotten at for repairs with great conrenielicc. It will lr noted particularly, that with this construction providing reaction engines whichproject beyond the sides of the easing and are situated on opposite ends of a common shaft, a balanced mechanism is provided, which not only insures little wear of the parts but makes possible a smoothrunning, quiet and effective machine. Each of the gears 16 is provided with a receptacle or trough 32 in which oil may be held for lubricating the parts.

of suitable bars 33. It will be noted that thelframe work 1 incases the gears and each trough 32. -Each wheel 15 is provided-with an oil-shield 32 which partiallysurrounds it and permitsoil to drip back into trough 32. The exhaustcasing foijeacl engineis provided with. ra .dially arrang steps 34 which are attached to-thecurved sides of the substantially cylindrical casing.

, Referring now more particularly to Figs.

5 to 10, there is found one. of the reaction engines as shown in detail. Each reaction engine comprises a' substantially cylindrical.

casing 35 which is provided 'withanelongated tubular portion 36 providing a recess adapted to receive an end of either of the shafts 7 or 8 mounted on the frame-work 1. The end of each shaft is provided with a key-way corresponding to a similar key-way in the casing and upon insertion of the key 37 therein the shaft and easing may be held in engagement. At the same time this mode of construction permits, the ready re- Each trough is attached to its adjacent end wall by means moval oi the engine from the shaftfor repairs or otherwise. The casing, as is shown more clearly in Fig. 7 is divided into two substantially equal halves which may be suitably bolted together by bolt; 38 passing from the front face of the casing through the rear half thereof. Suitable means may be interposed between the halves to "prevent leakage. The casing provides a substantially cylindrical chamber 39 in which is mounted a substantially cylindrical plug 40 which fits said chamber and is held in such manner therein that it is removable.

The plug is provided with a longitudinal passageway 41 of which the walls 42 are screw-tln'eaded portion 46 which is adapt- 5 ed to coact -with the screw-threads 44 of the plug .to thereby hold the nozzle in' position. The front end of the nozzle is provided with a hexagonal or other angular surface 47 which may be engaged by a Wre ch or other means for removal of the nozzle. This nozzle is provided with a longitudinal passageway 48 which gradually widens in area from the front end to the rear end thereof. The cylindrical plug is of greater diameter at its rear end than at its front end, forming a shoulder' thereby, and about the shoulder is arranged a flange 49 which is adapted to abut the inner part of the casing about the orifice 50 through which the elongated walls 42 of the plug project.

Joining the longitudinal passageway and communicating therewith at a point near the rear end of the plug are two transverse passageways 51 and 52 which are alined and which are coaxially disposed with re spect to two diametrically opposite discharge orifices 53 and 54 respectivel in the walls of the engine casing 35. he 'discharge orifices 53 and 5 1 communicate with the interior of the casing. In the rear wall of the plug and substantially in line with the axis of the longitudinal passageway of the plug is a screw 55 which pro ects into the space formed at the juncture of the two transverse passageways and the lon itudinal passageway. This screw is provi ed with a tapered face 56 which is adapted to deflect steam or other fluid from the passageway 41 into the transverse passageways 52 and 51 respectively. Screw 55 fits in passage 57.

Passing through the outer orifices-or dis charge outlets 53 and 54 of the casing, and forming coaxial extensions of the passageways 51 and 52, are respectively placed spur tubes 58 and 59, which are attached to the plug 40 in the passageways mentioned and serve to lead the steam therefrom to a point exterior of the cylindrical plug and into detachable discharge conduits hereinafter described. Situated in counter-sunk recesses 60 and 61 which are preferably diametrically disposed with respect to one another on the interior of the casing, are pipes 62 and 6; terrain: part of the conduits above mentioned. ' liiese pipes 62 and 63 are adapted to be detached from the casing and are provided resper tivelv at their inner ends with flanged portions 64 aiid'65 which are adapiit '0 aout and surround the oriflees 53 tlhq 54 in the casing; These pipes project through he orifices 53 and 54 and are adapted to surround and to communicate with'the conduits or tubes 58 and 59 and to thereby receive steam therefrom; thereby pipes 62 and 63comrnunicate respte-tively with the transverse passa eways 51 and 52. At the end opposite the flanged end of each of the pipes 62 and 63 isprovided a screw-threaded portion 66. Each pipe is adapted to engage the screw-threaded portion 67 of a recess in a substantially cylindrical collar (38 which surrounds the lower portion of a flattened conduitor reaction arm 69. It will be noted that the removable plug l0 abuts the lower faces of the flanged portions 64 and and thereby aids in retaining the pipes 62 and 63 in position. Further, according to the above, the discharge conduits comprise separable sections-62, 63 and 69.

As indicated each of the conduits or arms 69 is detachable and is provided with a flattened channel 70, extending coaxiall of the passageways in pipes 62 andi63i, w ich terminates at the extremity of the conduit or arm in a substantiall tangential outlet 71, having a curved wal adapted to direct the steam or other fluid used in the conduit or arm against the buckets 34 in each of the casings whereby a reaction will be provided tending to rotate the conduit or arm. The lower portion of each of the flattened conduits or arms 69 is substantially cylindrical and fits into the upper threaded portion of the collar 68. Between the upper face 72 of the cylindrical base portion of each conduit or arm and the inner periphery 73 of the upper wall of the collar .68 is inclosed a suitable packing 74 providing a ti ht joint between the conduit or arm and collar. Suitable packing 75 forms a tight joint between the upper end of the pipes and the lower face of the cylindrical base of the conduit or arm. This lower face is recessed, the recess being provided with converging walls 76 and 77 which lead to the narrowed channel running longitudinally of the conduit or arm. It will be seen by the construction as above outlined that the conduits or arms 69 will be held securely in place and that leakage will be practically prevent-ed.

In order to provide a suitable means for reversing the direction of rotation of the conduits or arms, means are provided for rotating the conduits or arms through an angle of 180. This is accomplished by providing the substantially cylindrical flanged portions 64 and 65 of tliepipes 62 and 3 with teeth 78 and 79 exteiidiii about the respective peripheries of the tanged portions. It is to be understood that these pipes are so mounted on the interior of the casing that they are permitted to turn about their loiigitudinai axes through the aforementioned teeth coactiiig with racks as hereinafter described. In turning, their motion of course imparted to the conduits or arms attached to each, and the conduit or arm being thus turned. as the direction of flow of steam fromthe outlet 71 reverses. the conduit or arm thereby rotates in a di rection reverse to that in which it would have operated prior to turning. The teeth 78 and 79 are ada ted to coact. with rods 80 and 81, respective y, whichas shown more clearly in Fig. 9, are situated substantially diametrically opposite one another, being attached to an annular collar 82 which is adapted to fit and reciprocate upon the extension 36 of the engine casing. The rods and 81 project through the casing lying in suitable channels provided therefor. On the inner face of the rods are provided rows of teeth 83 and 8-l respectively, which constitute racks and which eoact respectively with the teeth 78 and 79 on the flanged portions 64 and 65 and upon movement of these racks the pipes and conduits or arms Will-be turned through 180 or any interm diate angle desired.

ach collar 82 is provided with a circular groove 85. Coacting with the groove 85 on each of the engines mounted on the left in Fig. 3 is a depending finger of an arm 86. The arm is pivotally connected at its opposite end with one end of a lever 87. J oining the lower end of lever 87 of each engine is a longitudinal rod 88 pivotally attached to the side 2 of the frame. This rod 88 is extended somewhat beyond the end 4 of the casing and to it is attached a lever 89. To the other end of lever 89 is pivotally attached a transverse rod 90. To the opposite end of rod 90 is attached a lever 91, which in turn is connected to a longitudinal rod 92 extending along and pivoted to the side 3. This rod has mounted thereon near either extremity and positioned to coact with each engine on the right in Fig. 3 a lever 93. The other end of lever 93 is attached to one end of a bell crank lever 94, the other end of which is connected to an arm 95 whose free end has a depending finger coacting with the groove 85 in each collar of the engines on the right. A handle 96 is attached to rod 90 and it will be seen that by moving the handle to the left or right the arms 86 and 95 will be correspont'lingly simultaneously swung to the right and left. thus through movement of racks 80 and 81 controlling the directicn of rotation of the conduits or arms. lt is to be understood that the handle or other means for swinging the levers may be placed in any position for convenience in an automobile, boat or other structure.

Each of the exhau t casings l3 and. 14- is provided with a recessed portion 97 shown more clearly in Fig. l. in which the racks 80 and bit may reciprocate without striking the sides of the casing. The elongated portion 42 of the removable plug containing the nozzle also projects into this recess to such a distance that it communicates with the steam supply nozzle as which projet'rts through the outer face i of the recessed portion of the casing. This steamsupply nozzle may be adju ted toward and from the steam nozzle of the engine and is adjustably held in place by means of a set-screw which passes through the wall of the recess 97 and contacts with the side of the steam supply nozzle.

The operation of the device which should be largely obvious from the foregoing description is as follows: Steam is generated in the boiler 24 passes through the pipes :31 to the steam supply nozzles 98 which are so adjusted that they are held in close contact, with the engine nozzle in the removable plug 42. The steam passes into the graduated nozzle 45 gradually expanding during its passage, strikes the rear wall of the rc movable plug 40 by which and the faces 5t and 57 it is guided into the spur tubes 58 and 59, passing thence through the channels 70 and out through the channels it. The reaction in the conduits or arms caused by the steam forces each conduit or arm to rotate. The speed of rotation will vary according to the steam pressure, but it has been found in practice that with a pressure of approximately 600 pounds to the square inch, 7000 revolutions per minute has been obtained. Of course the machine may be,

operated on various pressures above and bclow 600 pounds. The Steam after passing from the conduits or arms into the .casing passes from this casing through the pipes 28 into the rescrvoir27. During the passage through the casing the steam will be largely condensed due to the large area of exposure therein. Further condensation will of course take place in the reservoir it. From reservoir 27 the products of condenszr tion are pumped up by means of the pump and steam again generated in the boiler, following once more the cycle of operation. already outlined.

It is to be noted that there is contpris-od in the engine very little material which will be affected by steam at high tQl]l[)tt'zttttlct: and which is liable to consequently burn out and permit leakage thereby impairing the etliciency of the device. ()n the contram there are substantially no joints on the in terior of the casing requiring packing. so that the passage of the steam is throughout substantially guided by metallic c nnt'artions. By providing the parts of such m tals that contraction and expansion are substantially uniform throughout, no chancetor leakage is provided,

some of the advantages of the dt vice are as follows: The device is light and compact. High horse-power may be obtained etii ciently with a device that is much lighter than engines of other types given a similar rating. The machine occupies little room, requires only a small foundation or base for support. and consequently is admirably adapted for use in structures which rcquire such conditions in a power machine of this type. By providing a removable plug and removable conduits in each engine. they may be readily taken apart for repairs and if necessary new parts or parts having varying structural features may be Substituted. For

'By making the conduits; or arms removable similar opportunity is provided for change Patent is:

or reinstalment. It'is further to be noted that any given engine may be removed from its shaft in case it becomes necessary to replace the casing or some other part of the engine requiring this renioval; The machine can then be either operated on three engines, or else if a spare enginef'be handy thismay be inserted and the efficiency of" the device may remain unaltered. It will thus be seen that with the advantages noted and those brought out in connection with the detailed description, a. highly practical and, efficient device is provided and one which achieves among others, the objects previously enumerated, completely and conclusively.

As many changes could be made in the above construction and many apparently Widely different embodiments of this invention could be made without departing from the, scope thereof, it is intended that all matter contained: in the above description or shown in the accom anying drawings shall be interpreted as il ust-rative and not in a,
