To all whom it may concern:
Be it known that I, Josn DEL Moran a citizen of Mexico residing at Ampere, East Orange, in the county of Essex and State vention is shown and. described in connection with a rotary engine I desire to'have it understood that the invention may be embodied in other types ofengmes.
In carrying out the invention'l provide an injector for conveying steam from the boiler to the rotor chamber and to return the exhausted steam from said chamber to the injector in a manner so that the exhaust.
steam is brought into contact with the steam from the boiler, whereby the energies oi both are, combined prior to the admittance oi? the steam'tothe rotor chamber. I
One of the chief characteristics of the invention resides in providing. an injector of novel construction, whereby its area can be readily and easily adjusted.
A further object of: the invention resides in the provision of means to automatically regulate the area of the injector during the various loads at which the engine is working.
It is also my purpose to provide the rotor of the engine with a plurality of sliding pis-v tons, which are designed to be maintained in eliective contact. with the wall of: the chamber bythe pressure within. the latter.
Clhe nature and advantages ofthe inven tion will be better understood. when the following detailed descr ption is read in connection wlth the accompanying draw1ngs,-
the invention residing intheconstruction,
combination and arrangement of parts as claimed. In the drawings forming part of this application like numerals of reference indicate.

Figure 4c is an enlarged sectional view taken atright angles to Figure 3. Figure 5 1s a sectional iew on an enlarged scale of the combining or mixing chamber including the principal elements of what I term the combining or mixing apparatus or injector. r j
Figure 6; is a sectional View on an enlarged scale; taken throughone of the sliding pistons. i I Referring to the drawings in detail 10 in dicates the base upon which the engine casmg is'mounjted, this casing being connected at ll and formed to provide a chamber 12 for the rotor-l". The casin 11 isproyided withan inlet port lt'ltangentially disposed beneath the rotor and an exhaust or outlet port 15, tangentially disposed above the ro-. tor, both of theseports opening at the same.
side of the casing 11. The rotor 13* is formed with radiallydisposedwslots 16 in each of which-is arranged a sliding piston 17. Each piston "ismadein two sections as clearly illustrated with the respective sec ,tions formed with longtiudinally'extending bores 18 which open atone side 01 the sect on to admit fluid with n the rotor chamber, the fluid operating against; the lower ends of the piston sections to force thelatter outwardly into effective contact with the wall or therotorchamber;-.The'rotor 13 is supported betwccn the disks .19 which are -carr'ied bythe shaft 20,-the disks being secured to theopposed sides of the rotor inany suitable manner. .Casings 21 are arranged about the disks 19 and cover the eccentricity between the disks and the casing 11', the
casings21 (being held tight against the sides ofthe pistons by means of springsQQ which provide a fluid tight connection between the said casings and pistons. Arranged at one side of the casing 11 is anoil reservoir 23 from which oil flows through a bore 2 1 into the shaft 20 and thence radially through bores 25in the disks "19. The'oil; spray is thrown up by centrifugal action of the rotor and covers the p istonsjand ring 26 andprovides ,eitective lubrication about jmoving partsoi the'engine. i l i Y Mountedupon the base 10 to one side of her formingpart of the injector and includis disposed in axial alignment with'th'eyinlet .the casing 1 1 is thecombining jmixingcham- I p ing a hollow tubular body portion 2Twhich port 14 of the casing 11 and secured thereto by means of suitable fastening elements 28.
Received by the tubular body portion 27 of the mixing chamber is one end of a conduit 29, the opposite end extending upwardly terminating to provide a semi-spherical portion 30 which is secured to a similar portion 31 of ilIl-GXllflllSl) pipe 32 which is bolted to the casing 11 about the exhaust port 15. The pipe 32 projects below the meeting edges of the semi-spherical portions 30 and 31 respectively terminating in close proximity to the upper end of the pipe 29. The space and valve seat have a valve fitted upon the adjacent end of the exhaust pipe 32. This valve controls escape of the exhaust from the pipe 32 through the port 34.
Arranged within the pipe 29 is a plurality of spaced curved partitions 35 which define passages 36 through which the exhaust from the pipe 32 enters the mixing chamber 27. These partitions extend an appreciable distance within the chamber 27 as shown. The central partition 35 has that portion disposed within the mixing chamber 27 formed to provide a steam chest or receiver whose upper and lower walls after meeting to form a narrowsection or throat 36 spread out in a divergent flare to define a nozzle 37 of the well known expanding form which guides and directs the motion of the actuating jet 36; Intermediate this steam chest is a supply pipe 38 which conveys steam from the boiler 39 to the steam chest or receiver. Arranged above and below the expanding nozzles are what I term mixing blades d0, these blades having their corresponding extremities pivoted as at 4:1 to the adjacent partitions These mixing blades slightly converge toward the discharge end of the mixingchamber 27. Arranged above and below the blades -10 are relatively long blades 42 which will be hereinafter known as delivery blades, the latter having their corresponding extremities piv-s oted as at 43 to the adjacent end of the pipe 29 and also disposed in convergent relation and spaced from the blades 40. As above stated, the delivery blades l2 are considerably longer than the mixing blades 40 and project beyond the chamber 27 terminating an appreciable distance within the inlet bore of the casing 11.
In practice, steam at high pressure is conveyed from the boiler 39 through the pipe 38 into the steam chest passing through the expanding nozzle into the space between the mixing blades 40. The steam thus expanded has its volume and velocity greatly increased, its pressure energy being converted into energy of velocity. The steam then passes between the mixing blades 40 and forcibly strikes against the converging delivery blades 42 and is thereby reduced in volume and velocity, or in other words the condition previously existing merely reversed, that is, this energy of velocity acquired while passing through the expanding nozzle being converted into pressure energy, so that upon passing between the restricted space between the free ends of the delivery blades as into the casing ll, the steam urg ing the pistons forward as it recovers its primitive potential energy or high pressure. The steam passing through the expanding nozzle and the mixing chamber 27 in the manner just described creates a suction in the, exhaust pipe 32 which lowers the pressure therein and momentarily closes the valve 33, thus prohibiting the exhaust passing through the pipe 32 to escape through the member e0, which exhaust is consequently drawn into the mixing chan'iber 27 passing through the space between the partitions 35 in thin sheets or streams at both sides of the discharge opening of the expanding nozale. lVhen the exhaust enters the mixing chamber in this manner, it mingles with the steam from the boiler, so that the energies of both are combined prior to the entrance of: fluid into the rotor chamber 11. Both the steam from the boiler and the exhaust from the rotor chamber are thoroughly mixed within the chamber by the construction shown, and both fluids move along together with a common velocity and increase momentum sufficient to force the combined masses oi the two fluids through the restricted passage between the free extremities of the delivery blades 4L2, and thereby overcome the high pressurcin the chamber let. The fluid admitted to the chamber l-t obviously strikes against the sliding pistons to forcibly rotate the rotor, a portion of the :(iiiid entering the bores: provided in the piston sections to hold the latter effectively in contact with the wall of the rotor cham her as above (ilescribed.
If the area of the discharge end of the delivery blades 42 were fixed at a given size, it would be too large when the steam supply from the boiler is reduced, and evidently to small when augmented, to permit sullicient passage for the increase of the mixture; consequently pressure would be raised at the exhaust and the steam wasted thereof. It is therefore my purpose to provide means to automatically regulate the area of the discharge end of the delivery blades 42 to compensate for any change in conditions. In carrying this idea into effect I provide a cylinder 4-5 at each side of the mixing chamber 27, and establish communication between these cylinders and the exhaust pipe 32 by means of branch pipes 46 terminally connected with the cylinder and communicating at a point above the mixing chamber 27 with a main pipe 47 which has one end suitably secured to the exhaust pipe 32 at a point immedately above the valve 33. Arranged for reciprocatory movement within each cylinder 45 is a piston 48 which carries a cross piece 50 at'the outer end thereof. Pivotally connected withthis cross piece 50 are the corresponding extremities of links 51, the opposite endsv of which are pivotally connected to the arms 52 arranged parallel to each other above and be-' low the cylinder .45. nected with the delivery blades 42 attheir point of pivotal connection43 as shown.
onsequently the delivery blades 42 are automatically adjusted to compensate for any change inconditions, the blades being controlled by the arms 52 which in. turn are actuated by the main piston 48 which floating between two balancing pressures, namely the atmosphere and internal pressure will readily respond to any change in conditions and automatically regulate the size of the discharge end between the delivery blades 42 during the various loads at which the engine is working. The valve 83 operates simultaneously for, the reason that the area of the exhaust opening must allow, at any given load, free exit for the volume of steam admitted into the engine at the pressure of the boiler, which steam is expanded down to the pressure of the atmosphere during. its
transit through the exhaust pipe 32 through the mixing chamber 27. By reasonof the construction and operation described, it is manifest that the engine will be enabled to utilize the absolute pressure developed by the steam in the boiler without the use of a condenser, and as there can be no escape of steam throughout through the exhaust pipe 32 which returns the. exhaust to the mixing chamber 27, the construction provides for both a-very efficient and economic engine.
While it is believed that from theioregoing description the nature and advantages of the invention will be readily apparent I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.
