OSCILLATING ENGINE.
SPECIFICATION forming part of Letters Patent No. 579,599, dated March 30, 1897.
Application filed July 8, 1895. Serial No. 555,227. (No model.)
To all whom/ it lit/L7] con/core..-
Be it known that 1, JAMES MOOARTNEY, a citizen of the United States, residing at Bessemer, in the county of Jefierson and State of Alabama, have invented certain new and useful 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.
My invention relates to that class of steamengines which oscillate on trunnions and are known as oscillating engines; and the objects of my improvement are, first, to provide I 5 a reversible oscillating steam-engine of a simple and cheap construction having a slidevalve operating in a steam-chest on the side of the cylinder in the usual manner; second, to provide a novel and cheaply-constructed 2o valve-operating device for an oscillating engine, the device attached to the bed-plate of the engine and operating the valve by the motion of a rock-lever pivoted to the cylinderhead, and, third, to provide a reversing device for oscillating engines of a simple and easilyoperated construction, the device pivoted to a stand attached to the -bed-plate and pro vided with a handle and the usual form of notched segment to hold it in the position desired. Heretofore the valve mechanism has been placed in this class of engines between the cylinder and the flywheel, necessitating many extra parts and increasing the danger in operating the valve.
3 5 My invention consists in locating all of the valve mechanism at the rear end of the engine, thus placing the cylinder between it and the fly-wheel, whereby a cheaper and simpler valve mechanism can be used than has here- 0 tofore been possible. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a vertical side view of my improved reversible oscillating steam-engine. Fig. 2 is a rear end view of the same. Fig. 3 is an enlarged detail longitudinal sectional View throughout the center of the cylinder. Fig. at is a cross-sectional view of the same through the center. Fig. 5 is an enlarged detail vertical side view of a part of the cylinderand the slide-valve-operating mechanism. Fig. 6 is a detail vertical cross-sectional View through the valve-operatin g link and the rock lever. Fig. 7 is a detail vertical rear view of the stand for the valveoperating link.
Similar letters refer to similar parts througlr out the several views.
The bed-plate A is made of any suitable metallic material and of any desired form. 'Irunnion'bearings B are attached to the bedplate in any desirable manner. The trunnion-bearings can be made of any of the usual forms, provided with caps to hold the trunnions to place in the hearing. The front end of the bed-plate is provided with bearings 6 for amain shaft, asshown. The main shaft can be of any of the usual forms of center crankshaft/s and fitted with balance wheels or pulleys in the usual manner.
The cylinder C is made of any suitable metallic material and provided with the usual form of heads on both ends, the heads attached to the cylinder in the usual manner. Two trunnions D D are formed on opposite sides of the cylinder. The trunnions are made circular to fit the bearings provided therefor and are adapted to oscillate therein.
A steam-chest E of the usual form is provided on one side of the cylinder, the steam-chest having the usual form of slide-valve F oper- 8o ating therein, the valve provided with a stem G, extending through a stuffing-box in the usual manner to the outside of the steamchest.
An inlet steam-passage H, having a suitable pipe connection, enters through one of the trunnions. The steam-passage extends upward through the shell of the cylinder and enters the side of the steam chest, as shown. The usual form of steam-ports I I'connects the steam-chest with the cylinder. An exhaust-portJ leads from the steam-chest downward through the shell of the cylinder and has an outlet through one of the trunnions, the outlet provided with a suitable pipe con- 9 5 nection to carry off the exhaust-steam.
A piston-head K is provided in the cylinder. The piston-head is made in any of the usual forms and has a piston-rod extending through a stuffing-box on the front head in I00 the usual manner. The end of the rod is attached-to the crank of the main shaft by anyof the usual connections or methods.
A bracket L, formed as shown, is attached by any suitable means to the rear cylinderhead. A rock-lever M is pivoted in the bracket. The rock-lever is provided at its lower end with a pin or roller N, formed on one side, a fork 0 being formed, as shown, on the head of the rook-lever to engage a grooved collar, as hereinafter described.
The metallic stand P, formed as shown, is attached by suitable means to the bed-plate in the rear of the cylinder. A valve-operati-ng link Q is pivoted in the head of the stand. The link is provided on its face with a curved groove R for the pin or roller N, formed on the rock-lever, to slide in as the cylinder oscillates. The operating-link is provided with a handle S to swing it on the pivot. The handle is provided with any of the usual forms of spring-catches to engage the notches formed in a segment T, extending upward from the stand.
A collar U is attached with a set-screw or other suitable means to the valve-stem G. The collar is provided with a groove V for the forked head of the rock-lever to operate in when sliding the valve as the cylinder oscillates.
In operating the engine the notched segment T is used to hold the operating-link in the desired position. The middle notch throws the valve on the center and the two o uter notches runs the engine in opposite directions. If the handle of the operating-link is set in the bottom notch, as shown in Fig. 5, and it is desired to reverse the engine, the
handle of the operating-link is moved upward I provided with a pin or roller; a stand P,valveoperating link pivoted on the stand, and provided with a curved groove, ahandle secured directly to the link and extending in a line with the cylinder, and a segment to lock the handle in place, substantially as described.
In testimony whereof I aiiix my signature in presence of two witnesses.
JAMES DICCARTNEY.
