ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 532,065, dated January 8, 1 895.

, Application iiled April 16, 1894. Serial No. 507,629. (No model.)

.To all whom it may concern: 1

Be it known that I, HENRY A. HOUSE, a citizen of the United States, and a resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Rotary E nfv gines, ot which the following is a specification, reference being had to the drawings ac` companying and forming .a part of the same.|

The subject of my present application for patent is a new and improved form of rotating engine adapted to be driven by steam, compressed air or the like, and of the general class known as cyclo-motors.

The special objects of the improvements which' distinguish 'my invention is to adapt such engines to marine propulsion, particul larly to the running of high speed launches, torpedo boats and thev like which require enginesof high efficiency, great power and speed in smallgcompass, andthe capability of ready and easy control and reversibility. The im-` provements which I have introduced in my engine have been devised with these objects in view. l

These improvements consist in a means for reversing the direction of rotation of the en-1 gine;in a novel and eective plan of compounding rotary engines, and in special fea-` tures of construction which will be described in detail below. Y* l The annexed drawings illustrate an engine to which my improvements are applied.

Figure l is an end view and part section of the engine being on line g/-g/ of Fig. 3, Fig. 2 is a diagrammatic development of the engine illustrating the principle or mode of operation. Fig. 3 is a central longitudinal section on line z-e of Fig. 4. Fig. 4t is a vertical cross-section on line x--x of Fig. 3.

A is the shaft which has its bearings in trnnnions A of the engine casing or frame which latter are journaled in supports A A and keyed thereto.

On the shaft A and keyed to the same is the rotary element of the motor consisting of a casting B in the general form of a circular disk or wheel with peripheral steam pockets or any other similar and proper provision for rotation'under the action of steam or air pressure directed through ports tangential or approximately so to the periphery of the disk.

series of pockets D.

t The disk B is formed with a plurality of sets of steam pockets or vanes which bear to one anothera certain definite relation. The pockets of one set, designated as C are formed inthe centralportion of greatest diameter of y the disk Iby a series of teeth or projections on the periphery thereof.

D similarly formed by teeth in portions of the disk of somewhat reduced diameter but of greater width, and outside of these are other similar pockets E in portions of the disk of still greater width and smaller diameter. The casing and vanes for this disk are so constructed that the steam under high pressureis directed into the pockets O from which it exhausts into the pockets E and from thence into the air, so that the capacity of the several series of pockets, and their peripheral speed will be proportioned to the pressure of thesteam acting upon them.

The construction which I have devised for this purpose is as followsz-At-one or more points the pockets C are closed by passing under a block as O through which extend and open ports O O as nearly as practicable tangentially to the disk and in opposite directions. Beyond the edges of said blocks Oare openings F in webs F between which the central portion of the disk revolves, and through these the steam as it expands in the annular .chamber O, passes into a second annular chamber G formed by thewebs F and webs G- which latter extend down below the To reach the chamber G however, the steam must first pass through ports H H in'blocks II, similar in construction and arrangement to those previously described except that the area of thelports is greater and `through which the steam is directed into the pockets D. Beyond such blocks H are the openings I in the webs G through which steam from the pocketsV D passes to and through ports K into pockets E and thence into an annular chamber J formed by the webs G and the outer casing J of the engine. Beyond the ports K are the main exhaust ports K. Practically, there are v'thus formed three disks of unequal diameter each containing in its periphery teeth, vanes or pockets of an area or capacity proportioned to its diameter and corresponding annular Next to these on one, Y or preferably on both sides are other pockets chambers in which the said disks are inclosed,

communication between said chambers being through partitions or blocks which close the pockets in the disk as they pass under them and which contain ports by means of which and openings in the partitions between the annular chambers, the steam admitted to the first series of pockets exhausts successively through the others.

The teeth or vanes which constitute the walls of the steam pockets are radial, and as the ports through which steam is directed into the pockets open in opposite directions the disk will rotate in one direction or the other according to the ports through which steam is admitted. I therefore provide with each pair of ports a controlling valve or cock as M having a handle M and arranged to connect the entering port asvM with either of the ports as C. The stems of said valves or cocks are extended, when necessary, to bring their handles into convenient position to be operated, and all the handles are made to pass through slots in, or to otherwise engage with a shell N mounted on the trunnions A and capable of limited rotary movement so that by turning said shell all the cocks will be simultaneously turned in one or the'other direction.

From the above description and by reference to Fig. 2 the operation of theengine will` be readily understood. Steam under high pressure is admitted through the ports determined by the position of the cocks, into the pockets C. This sets the disk in rotation and the steam escaping from the pockets as they pass from under the blocks C, expands in the chamber O. The only passage for the steam from this chamber is through'the openings F F, ports H H and pockets D into chamber G and although it has expanded to greater volume the greater area of ports H, the increased capacity and slower speed of pockets D enable it to do useful work. In like manner the steam still further expanding in the chamber Gpasses through the ports K, which are of still greater area, into the pockets E, the capacity of which isl greater and the peripheral speed lower than those of the pockets D and from thence the steamv passes off through the exhaust.

I do not limit my invention to an engine with three sets of pockets or vanes as herein described, as l may employ either a less or a greater number. On the other hand I do not claim broadly the plan of compounding engines herein set forth as I am aware that in:

rotary as well as other engines heretofore the steam at different-stages of its expansion has been utilized; but

What I claim is- 1. The combination in a rotating engine with a rotary element or disk having two or more sets of pockets of dierent capacity and relative speed and ports of corresponding ca` pacity for each set of pockets communicating with the exhaust of those of next smaller size and higher speed, as set forth.

2. In a rotary engine the combination with a rotary disk having portions of different di'- ameters, formed'or provided with peripheral pockets or vanes of a capacity or area inversely proportional to their distances from the axis of the disk, of a casing forming separate chambers for each set of pockets, and

ports for directing steam into the several sets said ports, and amovablep'a'rt towhich all of r said valves are connected whereby they may be simultaneously operated, as set forth.

4. The combination 'with the rotary disk having portions of diviferent diameters and widtlrfo'rmed or provided with peripheral steam pockets, the casing forming independent steam chambers for each series of steam pockets, ports for admitting steam from a boiler to the outer and smaller series of pockets, tangentially and in opposite directions, similar ports for admitting' the exhaust steam from one series of pockets to that of next greater capacity, valves for controlling the passage of steam throughl said ports, and means for simultaneously operating all the valves as set forth.

5. The combination of the rotary disk provided with series of peripheral steam pockets of different capacity the casing forming chambersn for the several series of pockets, ports for the admission of steam to the several series, cocks or/ valves for controlling said ports and the shell with limited rotary movement with which the handles of said cocks engage, as set forth.

6. .The combination with the disk having a central series of peripheral steam pockets, and one or more series of similar pockets on opposite sides in portion of the disk of less diameter and greater width, a casing forming independent chambersffor the several series of pockets, connected inl series through ports of areas proportionedto the width or capacity of Vtheir respective series of pockets, asl set forth.

HENRY HOUSE.
