vApplication filed July 23, 1921. Serial No. 487,127.

T 0 all tti/Lomz't may concern Be it known that l, GEORGE R. HUrr, a citizen of the United States, residing at Sasakwa, in the county of Seminole and State of Oklahoma, have invented certain new and useful Improvements in Steam Cylinders, of whichthe following is a speciiication. l.

rlhe present Vinvention relates to new and useful improvements in steam engines and more particularly to a cylinder construction. The primary object of the invention is the provision of means for controlling the intake andy exhaust ports of an engine cylinder. y

Another object of the invention is the provisionv of means actuated by the piston of a cylinder for controlling the intake and exhaust ports thereof. i i

Still another object of the invention is the provision of a slide valve actuated by the movement of the piston within the cylinder for controlling the flow of driving medium to and from the engine cylinder.

Another object of the invention is the provision of a steam engine cylinder which will be comparatively simple and inexpensive to manufacture, reliable and eiiicient in use, and readily operated.

lVith the above and other objects in view, the present invention resides in the novel features of construction, formations, combinations and arrangement of parts, to be hereinafter more fully described, claimed.,

V and illustrated in the accoimianying drawing forming a part of the present applie cation in which:

Fig. 1 .is an end view of a cylinder looking in the direction of the head;

F ig. 2 is a similar view looking toward the opposite end of the cylinder;

Fig. 3 is an end view of a piston;

Fig. t is a horizontal sectional view taken through the cylinder of the engine;

Fig. 5 is a detail view of the valve removed;y f

Fig. 6 is a longitudinal sectional view taken through the engine cylinder looking at the inner' side of the valve;

Fig. 7 is a transverse sectional view taken on the line 7-7 of Fig. 4; and

Fig. 8 is a side elevation of the piston removed.

Referring to the accompanying drawings, by suitable characters of reference throughout the several viewsthe numeral 10 `denotes in general an engine cylinder mounted upon a suitable base 11 and closed. at `:one end by an integral end 12, and at its oppo site end by a removable head 13 provided with a stufling box 14 through which the piston rod 15 operates. This piston rod 15 has attached to its inner end` a pistonl designed to operate in the usual manner.,

within the cylinder 10- or driving medium can be supplied to the cylinder and likewise exhausted therefrom.

A slide valve 21 is mounted in guides 22 within the engine cylinder and includes a pair of plates 23 and 23a connected by a spacing and guide rod 24. i

The plates 23 and 23a have inwardly pro jectings stops 25 and 25a for a purpose to be later explained, while formed in the valves 28 and 23a are openings 26 and 26a adapted to register respectively with the ports 17 and 18, and 18FL and 17.

Pockets 27 and 27"L are formed in the adjacent side of the piston 16 for receiving the stops 25 and 25u respectively, and allowing for the movements of the piston within said cylinder'. v

The pockets 27 and 27 are separat-ed by an abutment 28 designed to engage the stops 25 and 25" upon movement of the piston 1G for actuating the valve.

The openings 2G and 2GfL are so arranged that when the opening 26 is in registration with the exhaust port 18, the opening 26a will be in registration with the intake port 17a, and when the said opening 26 is in registration with the intake port 17 the opening 26a will be in registration with the opening 18a. r

In operation, when the piston 16 moves tor its outward limit of movement the driving medium can flow into the outer end of the cylinder through the intake port 17a and opening 26'"t in the plate 23, which obviously forces the lpiston 16 toward the opposite end of the cylinder allowing the exhausted driving means to flow out through the exhaust port 18 and opening 26 formed in the plate 23.

As the piston 1,6 moves in the direction of the arrow shown in Fig. 4L, the abutment 28 will engage the stop moving the valve 2l so that the openings 2G will register with the intake port 17 and the opening 26, with the exhaust port 18% permitting the driving' fluid to iow in the cylinder beyondthe opposite end of the piston reversing the moving of the latter.

This operation is continued until it is desired to stop the engine which can be aeeomplished in any simple and eHicient Inanner.

From the foregoing description taken in connection with the accompanying drawing, it will be manifest that an engine is provided which will fulfill all of the necessary requirements of such a device, and it should be understood in this connection, that various minor changes in the specific details of construction can be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any or' the advantages of the invention.

I-Iaving thus described the invention, what I claim as new is:

l. In an engine, a cylinder having intake and exhaust ports therein, a piston operating in the cylinder, a valve slidably mounted within the cylinder and controlling the intake and exhaust ports, said pistons having pockets formed therein, stops formed upon the valve for sliding movementwithin the pockets, and an abutment lormed upon the piston between the pockets for engagement with the stops and actuating the valve.

2. In an engine, a cylinder, a piston in said cylinder having pockets formed therein and an abutment Ybetween said pockets, guides Jformed within the cylinder, said cylinder having an intake and an exhaust portl In testimony whereof, I aix my signa-tureA inthe presence of two witnesses.
