OSCILLATING ENGINE.

SPECIFICATION forming part of Letters Patent No. 314,932, dated March 31, 1885.

Application filed May 10, 1884.

T 0 all whom it may concern.-

Be it known that I, ADAM H. HAFLEY, a citizen of the United States, residing at Ashley, in the county of Washington and State of Illinois, have invented certain new and use ful Improvements in Oscillating Engines; 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, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon,which form a part of this specification.

Figure l of the drawings is a side View of my device. Fig. 2 is a plan view of the same. Fig. 3 is a vertical transverse sectional View of the cylinder. Fig. 4 is a vertical longitudinal sectional View of the same, and Figs. 5 and 6 are detail views.

This invention has relation to improvements in that class of oscillating steam-engines in which reversing mechanism is used, and a steam-chest having a flat truly-planed side provided with ports to register with similar ports in an oscillating steam-cylinder, the said cylinder also having a plain engaging side, and the ports so arranged as to be readily converted into receiving and exhaust ports; and the invention consists in the construction and novel arrangement of devices, as will be hereinafter more fully set forth, and particularly pointed out in the claim appended.

In the accompanying drawings, A represents the frame of an oscillating steam-engine having formed in it the proper vertical bearings a and a for the horizontal shaft B,which carries the crank-wheel I) immediately outside of the bearing a. I

a is an arm of the frame A, extending backward from the bearing a at right angles to the shaft B, and a is an arm curving upward and outward from the frame A at any proper point below the arm a and having at its end the vertical bearing a parallel to the outer surface of said arm and to the crank-wheel I).

G is the steam-chest fixed to the arm a at a proper distance to the rear of the crank-wheel, and provided with a flat surface, 0, in which its ports open, and which lies in the same vertical plane as the outer surface of the arm a.

0 is a longitudinal partition dividing the steam-chest into equal and similar chambers, 0 and 0 respectively, above and below said partition.

0* is a vertical bearing formed in the surface 0 and partition 0, of the same height as and fellow to the bearing a.

D and d are ports in the chamber 0 situated immediately above the partition 0, and opening into the front and rear ends of said chamber respectively. E and e are similar ports for the front and rear ends of the chamber 0 situated immediately below the partition 0'.-

F is the cylinder having the flat surface f, equal in size to and fitting closely against the surface 0 of the cylinder. The cylinder is pivoted to the bearings a and c by the studs or trunnions f and f respectively, which stand centrally and at right angles, the latter from the surface f, and the former from the opposite side of the cylinder.

f is a spiral spring surrounding the trunnion f, between the bearing a and the cylinder, and serving to press the latter against the steam-chest, and render the surfaces 0 and f steam-tight.

f 4 and f 5 are ports in the central longitudinal line of the surface f, opening in that surface from the front and rear ends of the cylinder respectively. The ports f" and f are at such a distance from the trunnion f, lying between them, that as the cylinder oscillates the former will successively pass over the ports D and E, in the upper and lower chambers, respectively, and the latter over the ports (1 and e.

f is the piston, and f the piston-rod, connected to the crank'wheel b by the wrist-pin f.

G is a vertical pipe opening into the top of the upper chamber, 0, and provided with the escape or exhaust cock 9. H is a similar pipe opening into the bottom of the lower chamber, 0 and provided with a similar cock, h.

I is a horizontal steam-pipe joining the pipe G at '5, between the cylinder and the exhaustcock g, and J is a pipe extending vertically downward from I for a sufficient distanceand then bending at right angles and joining the ICO z is a throttle-valve in the stcam'pipe I, at any proper point between the pipes J and G, and j is a similar valve at any proper point in the pipe J.

K is the boiler, to which the steam-pipe I is attached at 70. k is a pipe passing from said boiler and coiled longitudinally in the water-tank L, and k is a cock between said tank and the boiler.

L is a feed-water-heatin g tank formed of-two equal and similar end portions united so as to be watertight by the flanges Z Z and bolts Z Z, 820., and containing the coiled pipe 7c, the end of which opens within said tank.

Z is. a plug in one end of the tank, which is removed when it becomes necessary to refill the same.

Z. is a feed-water pipe connecting the tank and boiler, and controlled by the cock F between them.

.Ihe operation of the different parts of the mechanism is as follows: It being desired to run the crank-wheel b forward, the throttle z and escape-cock h are closed, and the throttle j and cock 9 opened. Steam will then enter wheel I) will reverse.

the cylinder, when it begins to oscillate by way of the pipe J, lower chamber, 0 and ports E and e of the same acting as steam-ports, and the cylinder will exhaust by way of the ports D and d and' the upper chamber, 0 through the cock 9, the crank-wheel b at the same time being drawn forward. Upon closing the throttle j and cock 9 and opening the throttle z" and cook h the steam will enter the upper chamber, 0 the ports D and d of which act in this case as steanrports. The exhaust will take place through the ports E and e, the lower chamber, 0 and cook h, and the crank- It must be observed that when the cylinder takes steam from the port at one end of one chamber it exhausts by the port at the other end of the other chamber, and the reverse.

When it is desired to make use of the tank L, the cock is of the pipe Jo is opened, allowing the steam to escape from the open end thereof into the water in said tank and heat the same. When this is accomplished, the cock k is closed, and the cock Z in the pipe Z is opened to feed the boiler or the cock Z" may Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is

In an oscillating steamengine, the combination, with the steam-chest having the bearing 0, of the arm f the upwardly and forward] y curved arm a the steam-cylinder having the trunnions adapted to be supported by the said bearings, and th'e'spring f arranged upon the trunnion f, and engaging the inner side of-the said. curved arm a, to keep the cylinder pressed tightly against the steam-chest and form a steam-tight joint therewith, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
