Be it known that I, GEORGE W. SOUL, of Meridian, in the county of Lauderdale and :State'of Mississippi, have invented certain new and useful Improvements in Rotary Engines; .and I do hereby declare the following 4 to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which'it appertains-tom'ake and use the same.

' My invention relates to an improvement in rotary engines, its object beingto produce a rotary engine soconstructed and arranged that it can be easily, quickly, and eifectually reversed.

A further object is to provide a rotary engine having sliding wings or pistons, with `means whereby said wings or pistons will be` f forced outwardlyby the action of steam at a l A furtherobject is to construct "engine in such manner that steam higher pressure and independent of the steam.V

'I In the accompanying drawings, Figure 1 is an elevation of my improved rotary engine. Fig. 2 is an end view.' Fig. 3 is-an end'view with the head removed, some of theparts being shown in'section. `Figs. 4, 5, 6," 7, 8, and 9 lare detail views. Fig, 10 is aseparate view A represents the engine-casing', which is elliptical in form, the with a shaftr B, `which passes through the center of said' casing, said shaft being supported in journal-bearings B', carried by the heads C of the casing, said heads and the casing being secured together by means ot suitable bolts a.

Secured to'porV made integral with the shaft A is arevoluble head D, in each face of which, in .the shaftB, a recess b is made and to communicate with slots c, through the journal-bearings adapted which` extend o" in said jourfrom each head C and is provided with screwthreaded perforations for the accom modation of threaded bolts d', which la tter pass through and pointed ends being concentric close proximity to journal-bearings' B and of the shaft B are adapted at their pointed or wedge-'shaped lower ends `e2 to enter the slots c in the bush'- ings c', thus retaining said bushing in suchposition that mesita therein win be at ,the4

will appear farther on." The bushings may be securedto the journal-bearingsby :means of nuts es. y.

The revoluble disk or head D is provided with a series of, preferablysix or more, slots' e, each .of suiicient width and depth to receive a sliding wing" r piston f. The walls `of each slot are provided with V-sh'aped or other shaped `grooves e', iir whichisimilarlyshaped packing-"strips e4 are inserted. Both top of the journal-beating fora purpose which 'loc heads C of the casing are also made with V- Fshaped or other shaped grooves for the reception of similarly-shaped packing strips or rings f. Passing through the brackets d and journal-bearings B and communicating with slots c are .two pipes g g, which at their upper ends are connected together by means of a suitable coupling,said pipes g gbein g adapted to receive (in amanner hereinafter explained) steam independent of t-he steam whichdrives the engine; From this construction and arrangement of parts it will be seen that the steam which passes through the pipes g g will enter the grooves or slots c in the bushings c and journal-bearings B', from which it will pass to the recesses b and finally against the inner ends of the pistons f, thus forcing said Wings or pistons against the inner Wall of the casing A. The escape of steam from the recesses or slots e behind the Wings or pistons f will beprevented by the packing-strips e4,which,by the pressure of the steam and centrifugal action, Will be made to bear against the faces of the Wings or pistons and one side of the grooves and prevent the escape of steam past them. The packing-rings f are in a similar manner made to bear against the head y D and one side of their grooves.

.Made in the heads C of the engine are ports i z', arranged in proximity to .the edge or periphery of said heads at 4diametrically opposite points, the 'ports in each head being adaptedtocommnnicate by means ofduets fi'. With one of the ducts 'i' of each head C (preferably the upper one) apipe lE communicates, vwhereby to conduct steam through both ports in each head, the ports t' in one head being arrangedI or located near one side of the engine in an oblique line with each other, While the ports c' in the other head are arranged in the reverse position, so that steam passing .through the upper-port of one head Gwill drive the revoluble head D in one direction, and the steam passing through the diagonally opposite port of the same lead C will drive said head D in the same direction at the same time.

When the engine is to be used as a reversible motor, the upper ends of the large steampipesE are each connected with a four-way valve F, said valve being provided with an exhaust F and a steam-inlet pipe F2. The duct 7' of the valve F, through which live steam is to pass, is made of a size preferably about the size of t-he bore of the pipe E, while the exhaust ductj of said valve is made somewhat larger. made considerably larger than the live-steaml port j, so that the exhaust may be open sooner and later than the live-steam port, whereby when it is desirable that the steam be partly shut o in either direction the exhaust will not be cramped. v

From the construction and arrangement of the pipes E, ports z', ducts 1J', and valve F it will be readily seen that when steam is made to enter the engine through one of the pipes In fact this exhaust-ductjl is E it will exhaust through the other, and vice A versa.

By means of -the four-Way valve F thesteam may be made to 'enter either pipe E and exhaust through the other, according to the direction in which itis desired that the engine shall run. In like manner the engine may be easily and eectually reversed, either gradually or quickly, as desired, by simply manipulating the valve F,'which may be done by means of an arm k, lattached to-the squared stem k of the valve.l The steam-inlet pipe F2 is connected with the small steam-pipes g g by means of couplings l Z Z2, whereby steam will be permitted to pass'through said small steam-pipes g g before it passes through the valve F, and thus the ste m passing through.

said pipes g g and actin,a on the Wings or pistons f, as above explained, will not be controlled by the valve F, but, onV the contrary, will be entirely independent thereof. A lubricator G is connected with the coupling Z and is also connected with the 'steam-inlet pipe F2 by means of a pipe n. .From this construction it willbe seen that not .only the live steam, which maintains the pistons in proper position relatively to the-inner walls of the casing, will pass through the pipes, but lubricating oil will be made to How from the lubricator G through 'said pipes g g and thus supply'oil to the interior of the engine and thoroughly lubricate' all the working parts therein in a thorough and effectual By making the opposite ends of the casing A concentric with the revolving head-D the pistons f will have no movement in their slots in the revoluble head While they are subjected to the pressure of the steam.

In order to secure a smooth and durable wearing-surface within the casing A and to permit the removal of that surface should it wear, l provide a` Wearing-strip X of platesteel Within said easin g. This Wearing-strip consists of a straight strip of plate-steel of the same Width as the case (the steel being first tempered and ground) and of the proper length t0 t the inside circumference of the case.4 The ends of the strip are cut at an angle of about six degrees, and the strip being sprung into -the caseI the ends are abutted for, say, half their width and then are forced in, the angle compelling the Wearing strip or lining to spring out tightly against all parts of the case. Of course the heads when bolted to place will hold the lining firmly.

lIn rotary engines as they are commonly constructed the revoluble head is supposed to make a steam-tight connection with the casing at the-nearest point to prevent the steam from passing back.V I do away with this by using six or more pistons, the space between Ithem being, of course, one-sixth of the circumference of the head, and I make the-ports equal in length to one-twelfth of the circum- IOC iro.

in planes onesixth of the circu mferenceof the head apart. Thus there is always one piston between two passage of steam from one port to the other have a steam-tight connection with the cas: diameter of the casing is j ust-sufficient to permit the head D to revolve freely, (not steam-tight,) 'and the two ends of the casing (which .are modified ellipses) are segments of a circle concentric with the shaft ofthe engine, each being-one4sixth of a cpmplete circle or a part of a full circle divided by the number of pistons in the revoluble The importance of my departurefrom preform of -a casing `for a rotaryengine and substituting therefor the ellipse is that'the using the steam equally and simultaneouslyabove :and below the'revoluble head or runner arises from 'the fact that this gives a balanced steampressure on the revoluble head or runner and eliminates journal load and consequent fricn tion. Supposing that the steam was used on one side only, there would be a steamsprcssureQ-due to the eross-sectional area' of the revoluble head multiplied by the steam-pressure to be resisted by the journalse-#a pressure greater by many times thant'hatwhich was available for work.

The ports z' in the heads C of the engine are duplicates; but it is manifest-that in reversn ingthe'ports will occupy dilerent positionsthat is to say, at one time or when the engine is running in one direction the o'r-ts i of one head C will be inlet-ports and w en running in the reverse direction said ports (which 'were formerly inlet-ports) will be Aexhaustports, as above alluded. to.- This difference of position amounts to exactly onesixth of a v pistons are used, and as the ports are one-twelfth of a revolutionlong it is manifest that in the'close-par'tof the casing Ait will always be one-sixth-oafrevolul tion alsobetween the smaller endof the ports'` in one head to the smaller end-vof the com tig'uous port in the\other, Thus there iS` always one pistonbe tween ,f,two of the ports,

' which does away witljigthe. need `of the revov lublehead makingafsteam-tight jint with the steam will enter the casing above and below the revoluble 'head son. `The ports-ima", iii-desired, be located inthe casingA instead of the heads C.

VThe j ou'rnal-bealjn gs B' are provided externally with screw-threads ,for the reception ofg-stuing-boxes, which 'comprise collars 0 and-follower o', and between the former and bushing c flexibleor other My improved engine is a very simple sub-` stantial rotary motor. Itfpossesses no comof the porta-which prevents the Vions common practice of using the eccentric `2O fings for said shaft,

As the ports ofl eaclci` vhead C are connected together by a Vduct .or passage, L

D equally and inuni` subject to destruction by dust and grit. When used as a reversible motor, it runs eX- actly the same one way as the other and is controlled by one handle attached to a simple our-way valve. n j Having fully described my invention, what Iclaim as new, and desire to secure by Letters Patent, isv l 1.
