Be it known that LWILLIAM W. ANDnnWs,- a citizen of the United States, residing atLo`s.. Angeles, in the county of Los Angeles and. State of California, haveinvented a n`ew;and` useful Improvement in Rotary Engines, of which the following is a specication. j Q
My invention relates to rotaryengines and its objectis to provide an improved engine or motor of this class adapted to be operated by steam, compressed air, Water, or any other duid under pressure, and of greatereiiciency and simplicity than those with which I am acquainted.
The invent-ion consists in certain construetion and arrangements of parts hereinafter described, and particularly pointed outin the claim.
In the accom pany'ingdrawings, Figure lis a central transverse section taken on line l l of Fig. 2. and looking in the direction indicated by the arrow at the bottom 'of the drawing. Fig. 2 is a section on line 2 2 of Fig. 1,' excepting the cam N, roller O, connectingrods T, the valve-gear M M' S, the pulleys YY', and the fly-wheel U, shown in elevation. Fig. 3 is an end viewof the end opposite to that where the driving-pulley is mounted, the pulley and the Wheel being omitted.
A is, the piston-casing, cylindrical in form and surrounding the piston-chamber Z. It has an annular opening A' around the inner perimeter thereof, forming a passage for the nular rim B'of the piston-wheel B, filling up this opening and tightly fitting therein, so as to render the steam-.chamber Z steaml't has also steam or air The wheel B has spokes B" and is keyed to the main shaft E. Mounted on the outer perimeter of the rim B is the piston C, having packing C'. In the upper part of this chamber is the movable abutment D. This abutment has a vertical movement into and it is at its extreme downstroke, in whichy positionvitcompletely closes the piston-chamber at that point and forms an abutment for the Los ANGELES, CALIFORNIA.

in the drawings bythe momentum of the ilywheel U. After passing this point it will take live steam again. (A description ofthe mechanism whereby this is accomplished is explained farther on.) This abutment D is mounted on the stem H, which in yturn isaf- `fixed to the cross-head J. This cross-head is attached tothe upper end of the upright connecting-rods T, the lower ends of these rods being journaled on the free ends of the arms P and P'. VOn the free end of the arm P is rotatively attached the roller O, which roller is keptin contact with the cam N by the spring Q. As the cam N, revolving in the direction indicated by the arrows in Figs. l and 3, approaches the abutment `D the roller O, being in contact'with the' cam N, raisesthe roller O, and with it the free end of the arm P and also of P'. These in turn, by meansof the connecting-rods T, raise the cross-head J, and with it the stem H and the abutment D. The raising of this abutment gives a free passage to the piston C under the abutment. As soon as the piston has passed froinunder the abutment the shape of the main shaft E, on which is mounted the Wristpin M. On this pin is journaled the lower end of the pitman S, the upper end of the pitman being journaled on a wrist-pin Y' of the crank Y, which is keyed to the valve-stem' F',
steam or air which enters into the piston- ICO and on this stem F' is keyed the valve F,
whereby the rotation of the main shaft will impart to the slide-valve F the necessary oscillating motion to feed the steam or air to and cut it off from the chamber Z, as desired. The valve F being operatively connected with the main shaft E, as shown, will make one complete oscillation with each revolution of the shaft.
The parts being connected in the relative position shown in the drawings, e., more particularly the valve and the piston,) the engine will operate as I have hereinbefore described. steam one-half of its revolution and approximately one-fourth of its revolution by steam expausively and the remainder of the revolution by the momentum, there being but one steam piston-chamber, one piston, one steaminlet, and one exhaust, thereby greatly simplifying the device while adding materially toits efciency.
It will be further observed that the recess D in the abutment D is so shaped as to project the steam into the piston-chamber Z in the direct-ion of and against the piston, giving to the device greater efficiency than when the steam is discharged into the piston-chamberl at right angles thereto.
Having described my invention, what I claim as new, and desire to secure by Letters Patent,is f

In witness that I claim the foregoing I have hereunto subscribed my name this 8th day of March, 1899, at Los Angeles, California.
