UNITED STATES WOBTBEY H- WE L 0 LF Herm s some R AR STEAM NG NE- Application filed June 18,

The present invention relates to a rotary steam engine and has for its prime object to provide a ring-like casing with pistons movable therein and connectedwith a rotary disc or the like on a shaft and valve means for controlling the inlet and outlet of the steam and abutments for allowing the steam to expand between the abutments and the pistons to provide the rotary motion, and means for operating the abutments and valves in unison.

Another very important object of the in vention resides in the improvement of the arrangement of the parts to provide a compara-tively simple structure which is thoroughly efficientand reliable in operation, and otherwise well adapted to the purpose for which it is designed.

lVith the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed; r i a In the drawing:

Figure -1 is a sectional elevation of the engine embodying the features of my invention,

Figure 2 is a sectional view therethrough taken substantially on the line 2 2 of Fig ure 3;

Figure 3 is a sectional view taken substantially on the line 3-8 of Figure2,

Figure 4 is a sectional view taken sube stantiallyon the line 4-4 of Figure 2.

Figure 5 is a sectional elevation of the packing adjustingmeans,

Figure 6 is a face view of onset the valves. 4

Referring to the drawing'in detail it will be seen that the numeral 5 denotes a shaft with a disc 6 fixed thereto. A casing com prises ring-like'sections 7 and 8 which are secured together by bolts 9 or in any other, suitable manner. The inner edges of the casingsare provided with annular extensions 10. The disc 6 extends between the extensions 10 and the inner edges of the sections? and 8 and has flanges 11 which extend into the extensions 10. Annular packing 12 is disposed in the extensions and held against the lower edges of the sections 7 and 8 and against the flanges 11 by means of bolts 14 threaded into the extensions 10 and having their interior ends hollow as is indicated at 1927. Serial No. 199,717.

15 to receive packing engaging elements 16 which are spring pressed outwardly as'at 17 Lock nuts. 18 are provided on the bolts 14 so that after being adjusted they maybe locked against accidental displacement. On diametrically opposite sides of the disc 6 there are formed pistons 19, in the present instance, two in number. These pistons 19 are movable in the casing formed by the sections 7 and 8. The section! 8 is formed in the present instance with threehousings 20 having removable covers 21: These housings are formed with a central compartment 22 and side compartments 23 and 245 the latter two forming steam chests An inlet pipe 25 leads to theasteam chest compart ment 23 and-an exhaust steam pipe 2 6' leads from the exhaust steam chest compartment 1 24. Passages 27 have apertured communi cations 28 with the interior-of the casing formed by sections 7 and 8 and with the steam chest. 23 through apertures 29.

to pass through the passage 27 and apertures 28 into the main piston casing. A valve 32 is mounted in; the chest 24 and has passages 33 which may be brought into registry with apertures '34 leading into a pas-v sage 35 apertured in c ommunication with the piston casing as at 36. l

All of the casings or housings 20 are of identicalconstruction and for the purpose of clearness, only one will be referred to in detail as far as the speoiticstru cture is concerned. A cam element 40 is keyed on the shaft 5 and has cam humps 41 at diametrically opposite points in alinement with the pistons 19. Y A rod 42 is slidable valve 30 is slidable in the chests 23 and has through a bearing 43 in the inner end of the housing 20 andfhas ayoke44 engaged therewith 111 any suitable manner and hav ing its branches extending up throughbearings 45 into the chests 23 and 24 and has the extremities of the branches formed with i of one of the humps 11 the abutment 51 is swung into the compartment 22 as is illustrated in Figure 3, and of course at this time one of the pistons 19 is passing by the housing 20. As soon as the piston passes by and the roller 47 slips off the hump 41 the abutment 51 is swung back into the casing and the steam will expand between this abutment and the piston which has just passed by. V

The details of constructionhave been described with sufiicient particularity to now appreciate the full operation of the engine. The shaft, in Figure 1, is rotating in a counter-clockwise direction and as is apparent from Figure 2 one of the pistons namely the upper piston has just passed the uppermost housing 20 so that steam is entering through the inlet 25, steam chest 28, and as soon as the roller 47 moves completely oil the hump &1 said steam will pass through passages 31 and openings 29 into passage 27 and through apertures 28 to expand between the uppermost abutments and the uppermost pistons and drive said piston in Figure 2 in a counter-clockwise direction as said lower piston is being driven from the lower left-hand housing 20 as will be apparent without furtheir detailed description. It is to be noted that the exhaust passages are always open since the steam exhausting outwardly through the passages 34 maintains the valve 32 pushed back so that the passage is free.

In the same way the intake steam maintains the valve 30 in abutment with the wall in which the openings 29 are provided. It

i will be apparent that the steam may be enmerely. by way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the abovedescription.

Having thus descr bed my invention, what I clalm as new 1s:--

1. Arotary steam engine of theclass described comprising a ring-like hollow casing, a piston movable in the casing, a housing on the casing form-ed with a central compartment and a pair of steam chests one to each side of the central compartment, said housing provided with passages leading from the steam chests into the interior of the casing, a pair of valves one in each chest, a yoke having its extremities slidable in the chests, means for providing a loose connection between the extremities of the yoke and the valves, steam intake means associated with one chest, steam exhaust means associated with the other chest, said valve formed with passages to register with the passages first mentioned, the inlet valve being held inoperative position by the incom- 7 ing steam and the exhaust valve being held in inoperative position by the exhaust steam because of the loose connections with the yoke.

2. A rotary steam engine oft-he class deeach side of thecentral compartment, said housing provided with passages leading from the steam chests into the interior of the casing, a pair of valves one in each chest, a yoke having its extremities slidable in the chests, means for providing aloose connece tion between the extremities of the yoke and the valves, steam intake means; associated with one chest, steam exhaust means associated with the other chest, said valve formed with passages to register with the passages first mentioned,- the inlet valve being held in operative position by the incoming steam and the exhaust valve being held in inoperative position by the exhaust steam because of the loose/ connections with the yoke, an abutment swingably mounted in, the compartment, means for swinging the abutment in and out of the casing and the compartment, said means operating in unison with said yoke.

In testimony whereof I ture.
