Both tor, and the water and Kerosene supply the inner and outer sections of thepiston are -'val 'ves, by means of a single lever, the ma hollowed, out for the sake of lightness and ss 'nipulation' of which serves to stop,

start, or within the inner section isfitted a wear sleeve signed for the reception of rollers 14 extending inwardly from the innerv ends of wear plates 15 secured to the op osite ends of partitions 16, 17 and 18. T e'se partitions, as

shown in Figs. 3 and 4, are three inv number and are disposedradially With respect to the axis of the engine cylinder, and while the piston is designed to rotate independently of the partitions, a fluid tight joint is maintained lock 19, of Babbitt metal or other suitable material, retained in a recess in the inner edge of the partition and urged into close contact with the piston by a spring21, as shown in Fig. 1.

The partitions 16, 17. and 18' maintain at all times their radial disposition, and, as they are designed to remain in close contact with the periphery of the piston during the epicychc movement of the latter, they must necessarily reciprocate toward and from the axis of the motor. The partitions-are guided in their recipr'ocatory movement by radial ways or guide grooves 22, formed in the opposed .faces of the heads 3 and and receiving the wear plates 15 secured to the opposite ends of the partitions. To accomino titions the cylinder is formed with radial movable end walls or lates 24 for the pock-' ets 23 may be formed integral. with the cylinderheads, but they are preferably detachable as shown, in orderto facilitate access to the pockets for purposes of inspection and repair Without necessity for extensively dismantling the motor. I

The engine cylinder 2'is extended beyond the inner heads 3 and 1 to what may be termed the outer heads 25 and 26 retained in place by tie-rods 27 and constituting the outer walls of valve chambers 27 and 28 within which are located the supply and exhaust valves 29 and 30. It'will now/be noticed, by reference to Fig. 2, that the partitions 16, 17 and 18, connected at their innor ends by the piston 8, subdivide. the cylinder into three compartments, which, for convenience of description, will be designated A, B and C. Each of these compartments is provided with two supply ports located adjacent to its. opposite ends, those of compartment A being denominated A and A those of compartment B, B and B and those of compartment C, C and C Each of these ports is formed in the wall-of the cylinder and opens at its opposite ends etween the periphery of the piston and each partition by means of a yielding packing ate the parpockets 23 alined-with the ways 22 and closed into the chambers oithe supply and ex' haust valves and also opens at an intermediate point into the cylinder. This arrange{ ment of the ports will be clearly understood by reference to Figs. 1 and 6, it being noted that the opening 31, which places each' of the supply ports in communication with the interior of the cylinder, extends substantially the entire distance between the heads 3 and 4, although this opening may be'more restricted ii desired. While each of the cyl inder compartments is provided with two supply ports, as stated, one port only of each compartment is designed for-use when the engine is running in a given direction, the duplicationoi' course being made necessary in order to permit the reversal of the motor. In order,..therefore, to provide for the clossay, one; port for each compartment, 1 mount within the chamber 28 what may be termed a reversing valve 32, see Figs. 1, 1, 6 and 12. The reversingvalve 32 is in the form of a disk rotatably mounted on the shaft 5 immediately adj acent to the head 4 and having an annular fiange33 opposed to the peripheral wall of the chamber 28 and having three openings 34., 35 and 36, which, according to the position of the valve 32, are brought in apposition with the orts A, B and G, or the ports A B an O In other Words,

mg of one series of supply. ports, that is to by means of this reversing valve 32 one series of supply portsare opened and the other closed, accordingly as it is desired to operate the motor in one direction or ,the other. To efiect the necessary change in position of the reversing valve, it is designed to be shifted on the shaft 5 as an axis, but the mechanism whereby this operation is effected will be described later. Itwill be assumed, however, for the present that the -reversing valve 32 is in the position shown in Fig. 4, the openings therein being oppov site the ports A, B" and C, and constituting continuations thereof in'efl'ect. The motive fluid is -designed to befadmitted to these ports from the chamber 27 in successive order and the control of the supply is eiiected by the valve 29, heretofore referred to as being located within the chamber 27.

The valve 29, like the reversing valve 32, is in the form of a disk which is provided with an annular flange 37 opposed to the inner face of the flange 33 of the controlling valve and provided with a slot 38 extending around approximately one-third otthe valve. As this controlling orsupply valve 29 normally rotates with the engine shaft, the slot 38 will be presented opposite the supply ports in succession. and will maintain the communication between a given port and the source of motive fluid supply for a considerable interval, that is to say, for a period of piston travel corresponding with the length of the slot 38. Of course, when the 35 admission of motne fluid to the upper end the engine, the controlling valve 29 must be shifted relative to the piston in order to reversing valve is "shifted to close the supply for the reason that the valve 29 will have ports A, B and C and to open the ports closed the port A before the piston reaches A B? and (3 for the purpose of reversing that position in compartment B which corcausel the slot 38in said valve to move 0 posite the )orts at the proper times, notwithstandingthis reversal of normal conditions. It is desirable, however, that the normal operation of the engine be fully understood before these various arrangements for'its reversal are considered, and therefore, before describing the mechanism for shifting the controlling valve to accommodate the reversalof the engine, I will pass to a consideration of the mechanism whereby the motive fluid, having operated directly and expansively on the piston, is used over again efore being iinally exhausted. i

It will be noted, by reference, to Fig. that the partitions and piston serve to divide the interior of the cylinder into three distinct compartments. 'lhese compartments are identical, both in proportion, and in equipment for the supply and exhaust of the -motive fluid. I will, therefore, first describe the operation of the engine during" the traverse of one compartment by the piston and" will then attempt to make plain g the manner in. which the several compartments are related one to another in the operation of the motor.

In the position of the parts-shown in Fig. 2, the piston has just arrived at a position ,where it may be efl'ectively propelled by the of the compartment A through the supply port A and as a matter of fact, is being propelled by motive fluid so admitted. his

initial admission of motive fluid to the compartment is, h'owey er, in the form of exhaust from another compartment, it being obsen'ed that the compartment A cannot be supplied directly from the chamber 28 for the reason that the slot 38 in the controlling valve has notyet reached a position opposite the port A, see F i 4. Therefore, the ini-' tial movement of t 1e piston in the compartment A will beiefl ected by the admission of exhaust fluid to said compartment from another compartment, to-wit, the compartmentC, and after a predetermined piston travel, to-wit, from 'the position shown in Fig. 2 to that shown in Fig. 3, the supply of exhaust fluid to the compartment A will ciently to open the port A.

have been cut oil in a manner to be hereafter described, and a supply of he e'fluid will then be furnished from the chamber 28 since the controlling valve will now have moved suffi- The piston will no iv contiriue' its movement until ;it reaches toits present os ition in compartmentA, -a portion of this movement being eflected 55 by the, useofthe motive fluid expansively We have seen that the idirect admission of the fluid to the com )artments is controlled by the valve 29, t 1e slot or opening 38 in which is brought suclcessi ely in apposition to the ports A, B" and to admit motive fluid directly from the chamber 28 to the several compartments A, B and (7 in successive order. instrumentalities wherebywthe motile fluid, having been used directly and expansilely, in one compartment, is automatically supplied to the next compartment to eil'ect the Initial movement of the piston therein, and the provision which is'made for finally exhausting or clearing each compartment to avoid back pressure.

The head 3 of the cylinder 2 is provided with three exhaust ports A B and one for eachcompartment and in equidistant relation. At the outer side of the'head 3, to-wit, in the chamber 28, is located the combined exhaust and compounding valve 30 having the form of a hollow disk keyed to the motor shaft 5 and provided with a par tition 39 S1lb(li'\ iding the interior of the valve into two compartments 40 and il. The compartment 40, which may be lillOWIl as the compounding compartment of the exhaust r'al'ye, is closed, with the exception of two openings or 'ports-42and 43 opening through the periphery of the valve, and two diametrically opposed ports 44 and 45 in the side wall of the valae nearest the head 3 of the cylinder 2 and arranged to be brought into apposition with the exhaust ports A, B, and C in a manner to be described. Each side wall of the other or exhaust compartment 41 of the alxe 30 is pro sided with a long arcu'ate slot 46, likewise ar- Jranged to come opposite the, exhaust ports of the cylinder. The construction of the valve 30 is clearly shown in Figs. 1, l3 and 14 and its relation to the various ports of the motor, is clearly indicated in dotted linesin Fig. 2. It will be noted, by reference to the latter figure, taken in connection withFig. 3, that theport 44f-Tand the combination valx e 30 is opposite the" exhaust port C of the motor compartment C, that the port 42 in the periphery of the valve is in partial ap- I will now describe the.

position to the supply port A, and that the slots 46 in the valve are opposite the exhaust port B of the compartment B, attention being further directed to the fact that the peripheral port'43 is opposite and closed by the wall of the cylinder, that the side port 45 of the valve is opposite and closed by the head 3' of the cylinder, and that the exhaust port A of the compartment A is covered and closed by the piston 8.

We may now understand more clearly the operation of the motor, since it will be evident that the'right hand ends of all of the supply ports will be closed by the controlling valve 29, see Fig. 4, and that the left hand ends of all of said ports will belikewise closed, with the exception of the port A, which, as we have seen is in partial opposition with the peripheral port 42 of the controlling valve. The motive fluid, which has now performed its function in the-compartment C of the motor, will escape through the exhaust port C and valve port 44, into the compounding compartment of the valve 30 from whence it will ,escape by way of the port 42 and the supplyport A to the upper end of the com partment A. The exhaust fluid from the compartment 0 being thus-liberated within a chamber defined. by the partition 16, the periphery of the piston, and thewall of the cylinder, will expand against the partition and cylinder which constitutes a fixed abutment andnecessitate the movement of the piston. As heretofore stated, this continues until the port 42 of the combination valve has moved entirely past the supply valve A, when, as will be evident, the supply of exhaust fluid to the-compartment A from the compartment C will cease and the compartment A will be supplied with high pressure fluid from the chamber 28 by the opening of the right hand end of the port A by the controlling valvc 29. I

it will, of course, he understood, that the compartment C is not entirely depleted by its co.nm-unication with the compartment A,

since the communication is necessarily cut off long before the pressure in the-co1npart ment 0 has been reduced to atmospheric. It is therefore desirable to completely exhaust or clear the compartment Gas soonlas the communication between the compartments C and A has been cut off by the movement of munication with the outer air by way of an exhaust pipe 46. This will be better understood by reference to the position of the parts shown in compartment B, which in thepresentposition of the engine is cleared. Thus, to recapitulate briefly; the upper end of the compartment A in Fig. 2 is receiving the exhaust fluid from the compartment C and the compartment B is completely exhausted.

When thepiston reaches the position shown pressure fluid directly from the chamber 28 and the compartment C will be cleared. The piston will now continue to advance under high ressu-re,'but beforethe port 42 in the periphery of the combination valve 30 reaches the supply portB of the compartment B, the controlling valve will have closed the right hand end of the supply port A, thus cutting ofl'the supply of to the compartment A. After this automatic igh pressure fluid cut-off is eifected, the motive fluid in the compartment A is used, expansively until the port 42 of the valve 30 reaches the supply port B of the compartment B, when, as will be evident, the piston will have covered the exhaust port A of the compartment A-and the fluid will be exhausted from said compartment to the compartment B by way of the port A in the cylinder, the ports 44 and 42 of the valve 30, and the supply port B.

The piston will then be advanced acrossthe compartment B in the manner described ,in connection with its advance across compartmentA, said compartment first taking the exhaust fluid from another compartment,

next taking high pressure fluid from the ehamber'28, next permitting the advance of 1 the piston by-the expansion of the fluid, next exhausting into another compartment, and flnally being completely exhausted or cleared. For the purpose of relieving compression in the pockets 23 above the partitions, the top wall of each pocket is provided with a vent 47.controlled by a needle valve 48, and in order that any motive fluid escaping into the pocket around the partition may be discharged from the motor, an exhaust passage 49 is led from the vent 47 to the chamber 28, see Fig. 1.

The foregoing constitutes a description of a complete embodiment of my invention, viewed. in its broader aspect, since it is capa-. ble of being operated by a motive fluid su. plied to the chamber 27 from any suitab 6 source, and since without further addition, the engine is capable ofpractical operation in one direction. I shall now proceed, however, to describe a further development of the invention, having for its object the provision of means whereby the engine may be with two supply ports. The arrangement of 75 in Fig. .3, the compartmentA will take high I I each is identical except that said ports are which are now closed, the engine will operate located adjacent to opposite ends of'a come have also seen that the rej partment.

vers-ing valve 32 is designed to open one'sej ries and close the other.'so that, taking the com artment A as an example, the motive fhiit will be supplied to the lower end of the compartment instead of to the upper end thereof, as 18 the case when the piston is moving f in the direction indicated by the arrowi'n Fig. 2. It willnow be observed that ifthe reversing valve 32 is shifted so as to close the right hand. ends of the supply ports A, B and C, and open the ports A B'tand C", and the controlling valve 29 is shifted so that the slot therein will bear the same relation to the open ports that it formerly bore to the ports )recisely in the manner heretofore described, lmhin the reverse direction, since thefunctious heretofore performed'by the ports 4.4 and 42 of the combination valve'30 in connection with the ports A, B and C, will now be performed in the reverse operation of the motor by the valve ports'45 and 43 in connection with the supply ports A". B and C While many forms of mechanism may be utilized for the shifting of the controlling and reversing valves to re\ erse the motor, I have shown a simple arrangement whereby both of these elements may be shifted simultaneously, though in clill'crent degree, by the manipulation of a single lever. The controlling valve 2!) is provided. as shown in Fig. l with a comparatively long hub encircling the shaft. and extended outwardly through a stulling box 51 screwed through an axialopening in the head 25. To the outer end of the huh 50 of the controlling valve is secured by any suitable means, as for instance, a set screw 52. a sleeve 53 provided with a pair of cam slots 54 'l'orthe reception of rollers 55 carried by a sliding collar 56, splined on the shaft 5 .to compel its rotation therewith, and extended into the sleeve 53. .rs longitudinal movement of the collar 56 is obviously essential to the relative rotary movement of the shaft 5 and the sleeve 53, it follows-that the normal retention of the collar against movement longitudinally of the shaft will compel the controlling valve to rotate with the shaft as the latter rotates. To effect the shifting of the controlling valve 29 relative to the shaft when the reversal of the motor is desired, it is simply necessary to shift the collar 56 longitudinally on the shaft, when, as will be evident, the engaglement of the rollers. 1

with the slots 5% w l compel the cylinder 53 and the valve 29 fixed thereto to rotate on thesh'aft. I therefore provide the outer end of the collar56 with the circumferential groove 57, engaged by a pin 58 extending laterally from a controlling, lever 59 suitabl fulcrumed at apoint above the collar an provided with a spring latch GOengaging a toothed segment 61 to retain the lever in its adjusted positions. .Xormally, the lever stands in-the position shown in Fig. 1, but, I

in the manner described, I extend the lower end of the lever 5Q beyond the collar 56 and attach to its extrennt-y a connecting rod 62, which is in turn connectedt'o the long arm of a bell-crank lever 63 fulcrumed on a suitable bracket 64 extending from the head 25, or any other iixedpart. The short arm of the lever (53 is bifurcated for the reception of a crank arm 65 extending laterally from the outer end of a horizontal shaft 66 extended through a bearing 'sleeve 67 in the head. 25, and provided with a suitable gland 68 tolinsure a fluid tight joint, preventing the escape of the motive fluid around the shaft 66 from the chamber 28. To the inner end of the shaft 66 is secured a rocker 6S) engaging a recessed lug Tl) projecting upwardly from the outer-edge 'ol' the reversing valve flange 33, see -ligs.l and 12. Thus, when the lever 59 is shifted to reverse the position of the controlling valve 29, the bell crank lever (33 will be simultaneously swung to rock the shaft 66 and thus cause the rocker 69 to shift the reversing valve 32 to move the ports 34. 35 and 36 therein from the ports l3 and td the ports A", B'tand (7". l urthernnlrc, by this cmmcction of the controlling lever 59 with the controlling and reversing valves, it is possible uotonly to con' trolthe direction of rotation oft-he engine,

but also-the speed of the latter, since by I Opposite an opening 71 in the head 25 is secured a retort 72 inclosing a heater 73.

Oil and water pipes 74 and 75 are extended into the retort and equipped. with spray nozzles 76 and 77 from which oil and water are sprayed against the vaporizer. Each nozzle is equipped with a conical deflector 78 surrounded by a flared passage 79 having spray apertures 80 in its bottom wall. The pipes 74 and 75 are'sup'plied from waterand oil tanks 81 and-82. The supply is con trolled by valves 83 and 84 having operating arms 85 and 86 connected to the lever 59 by rods 87 which, as we have already seen, is operatively connected to the su ply and reversing valves of the motor. 'F rizer 73 is of refractory material and incloses heating coils 88 screwed upon a plug 89 re tained by a nut 90, the plug and nut being 'se arated from ,the wall of the retort by insu ation 91. l he feed wires 0 and b for the heating coils are connected to'the posts of a dynamo 92 operated in any suitable manner. The lever 59 is fulcrumed on the plug 89 as indicated at 83, the plug also constituting a support for the rack 61 provided with an 1 eye 94 surrounding the plug. 'In addition to the water and oil, air is supplied to the retort under pressure from a tank 95 through an air sup ly pipe 96 containing a glo e va ve 97'. he air pipe is led to an air dome 98contain1ng a spring pressed air valve99,

Obviously,'a motor constructed in accordance with my invention is adapted for general a plication as a power generator, regardless of the characterof work to be performed or of the specific nature of the motion transmitting mechanism employed in connection" therewith; .Furthermor'e, the invention in its broader aspects comprehends a motor construction ca able of being operated by any expansive uid,-as for instance, steam or compressed air, although it is preferred, as heretofore stated, to operate the motor by the expansive force of .a fluid composed of kerosene'vapor and steam.

It is thought that from the foregoing the construction and operation of-my motor will be fully comprehended; but, while the present embodiment .of the invention appears at thistime to bepreferable, I wish to be distinctly understood as reserving the right to effect such changes, modifications and variations of the illustrated .structure as may come fairly within the scope of the protection prayed.
