ROTARY-ENGINE REVERSING- GEAR.

SPECIFICATION forming part of Letters Patent No. 395,646, dated January 1, 18189. Application filed February 8,1888. Serial No. 263,328. (No model.)

To to whom it may concern.-

Be it known that I, OYRUs BAILEY, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Rotary-Engine Reversing-Gear; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in the improved con struction of a rotary engine and reversinggear for the same, hereinafter to be described.

In the drawings, Figure 1 shows an end view of the engine with the lever for operating the reversing-gear. Fig. 2 is an inclined. axial section of the same on line 2 2, Fig. 3. Fig. 3 is a vertical cross-section of the engine, taken on the line 3 of Fig. 2. Fig. 4 is a section taken. on the line 4 4: of Fig. 2, show ing the end of the crank-cylinder with the reversing-valve mounted on the same. Fig. 5 is a horizontal, axial. section of the enginebearing, showing in detail the apparatus for controlling the reversing-valve. Fig. 6 is a vertical moss-section taken on the line 6 (i of Fig. 5. Figs. 7 and 8 show the reversingvalve in cross and longitudinal sections.

Throughout the drawings like letters refer to like parts.

The construction of my improved engine, as illustrated in the drawings, is as follows:

A is the standard and easing of the engine, cast in one piece.

A is the face-plate, bolted onto the part A, as shown in Fig. 2, and thus inclosing the entire mechanism.

B is the crank-disk, mounted on the shaft (1, which runs within the bushing d, mounted in the casing A. The packing-gland 0 enables the joint about the crank-shaft to be so packed as to prevent the escape of any steam which may work between the bearingsurfaces. To the crank-disk B are bolted the cylindrical piece B and the plate B". constitute what I call the crank-cylinder. The plate 3 is extended in the form of a cylindrical thimble, which is represented by the letter F in Fig. This fits over and revolves upon a projecting boss, f, formed on the face-plate A, which furnishes an additional bearing for the crank-cylinder in line lating packing-piece X.

parts E, D ,and X are arranged in the other These togetherwith the crank-shaft (Z. \Vithin the crankcylinder is a partition, V, dividing it into two parts, as clearly shown in Fig. 2. In one part is mounted the piston E and the rotary packing-cylinder D. Steam-tight connection between these two parts is afforded by the oscil- In the same way chamber. The rotary packing-cylinders D and D are provided on their faces with packing-rings 1'), as shown most clearly in Fig. 2. The rotary cylinder I) is also provided with an extended cylindrical boss, 0, on which its companion cylinder D is j ournaled. The cylinder D in its turn is journaled upon the eccei'itric-stinl C, which has a tapered bearing in the face-plate A.

Steam enters the engine through the inletpipe I and is delivered to the steam-space 2'. (Best shown in Fig. 4.) From this it passes at proper intervals through the openings Z Z in the projecting boss F to the passages g g in the adjustable reversing-valve, and through the passages h It and R R in the plate Bto the steam-ports 0'51", opening into the spaces behind the pistons E E.

The valve G, having the passages g g, is circumferentially adjustable on the boss F and revolves with the crank-cylinder. Its adjustment upon that boss is fixed in the following manner: In the projecting thimblelike part of the valve G are two oblique slots, M and M, as shown in Figs. 5, 6, and 8. In the part F are corresponding axial slots. Mounted upon the valve G is the ring O,having projecting pins S S and a groove, '0. These pins pass completely through the slots M M and into the slots T T in the parts F. It is evident, therefore, that the adjustment of the ring 0 along theline of the axis of the crank-cylinder will throw the valve G to one side or the other so that its ports 9 will register with the passages 71 h or the corresponding set of passages, 10 7a.

The motion of the ring 0 may be controlled in a variety of ways. My preferred construction is that shown in Figs. 2, 5, and 6. Reg istering with the groove 0 are projections 0 and 0 on sliding pieces N N, which are mounted in the projecting boss f of the faceplate A. Packing glands 25 t prevent the leaking of any steam which may work be tween the parts of the engine, and also guide the pieces N N. To these latter are pivoted by the pins K K links m m, which are in turn connected to the two branching arms a n of the lever L. This lever is pivoted by the pin q to the bracket Q. It is evident, therefore, that a to-and-fro motion of the lever Ii willreverse the engine.

The object of the eccentric-stud O, previously described, is to afford means for taking up the wear of the rotary packing-cylinders D D. \Yhen this is to be done, the nut Uis loosened, the stud turned by a wrench placed 011 its squared end a, and then again drawi'i tightly into its tapered bearing by setting up the nut U.

The operation of my engine may be briefly set out as follows: Steam is admitted at the inlet-pipe I, and, passing to the steam-space 1', is from thence distributed to either or both of the chambers in the erank-cyliiuler, accord in g as either or both of the openin Z Z are in connection with said steam-space t. It is evident that each of said openings will be in such connect-ion during about three-quarters of the revolution with the proportion of parts shown in Fig. 4. The position of the valve G determines whether the steam passing through the openings Z Z shall be conducted through the ports h h or to the opposing set, is k. I11 the state of affairs illustrated in the drawings the valve G registers with the ports h h, and the steam is admitted behind the pistons E E when the engine is .rotated in the direction of the hands of a watch if looked at as in Figs. 1, 3, 4:, and 6. The exhauststeam 011 the other side of the pistons E E is allowed to escape continuously through the ports and passages terminating at. the ports 1.: into the exhaust-chamber,lV, which almost entirely surrounds the crank-cylinder and from which the exhaust-steam escapes through the passage Y. (Shown in Fig. 2.)

The general construction and principle of operation of my engine have been fully set out in my application filed September 27, 1886, Serial No. 214,616, and to such I make no claim in this application.
