IMPROVEMENT IN OSCILLATING STEAM-ENGINES.
Specification forming part of Letters Patent No. 130,157, dated August 6, 1872. I
.tion and to the letters of reference marked thereon, in which- Figure 1 is a side elevation of my improved engine. Fig. 2 is an end view ofthe same.
In the drawing like parts of the invention are pointed out by the same letters of reference. 1
The nature of the present invention consists in certain improvements, as more fully hereinafter set forth, in the construction of oscillating steam-engines, which improvements are intended to be applied more particularly to engines of small capacity; the object of the improvements being, by the employment of a spring or like device of sufiicient capacity to sustain the weight of the cylinder, to admit of a single trunnion being employed with the cylinder, and also to allow of the adjustment of the cylinder to the steam-chest by means of a bent lever and weight, as fully hereinafter described.
To enable those skilled in the arts to make and use my invention, I will describe the construction and operation of the same.
A shows the boiler, supported by the legs B, and 0 shows a drum secured upon the top of the boiler B. D is the steam-chest formed upon the top of the drum 0. This steam-chest D is provided on one side with the inlet and outlet ports for the admission and escape of steam to and from the cylinders E. E is the cylinder, provided with a trunnion, F, cast upon the same. F shows the trunnion cast upon the cylinder E, and passed through an opening in the steam-chest D. The end of the trunnion passed through the steam-chest is provided with an opening for the purpose here- .inafter explained. G is the piston-rod, one
end of which is inserted in the cylinder E, in which it is free to play, and the other end of which is received upon a stud inserted in a crank-arm, H, secured upon one end of the driving-shaft I. I shows the driving-shaft,
held in proper bearings in the frame J, upon which shaft is secured the fly-wheel K and pulley L, by which power is transmitted. M shows a spiral spring, one end of which is attached to the cylinder E about centrally, while its opposite end is attached to an upright, T, rising from the steam-chest D. This spring is made sufficiently strong to sustain the weight of the cylinder, so that the hooked lever, to be hereinafter described, is assisted and enabled to hold the cylinder steam-tight against the steam-chest D. N shows a bent lever, notched upon its upper side, pinned within the lugs 0,
cast or secured upon the upper side of the drum 0, the lever N being free to turn upon the pin passed through it. P shows a hook connecting the cylinder-trunnion and the bent notched lever, said hook entering the open ing in the cylinder-trunnion F. Q shows a weight placed upon the bent notched lever N, the position of which weight may be varied at pleasure. Such being the construction, the operation is the same as in the ordinarily-constructed oscillating steam-engine.
The particular advantages resulting from the construction just described are to be found in the fact that by the use of a spring, M, or like device of sufficient power to sustain the weight of the cylinder, the lever N, to which is attached the hook P, is the better able to hold the cylinder steam-tight against the steam-chest. Thus it will be seen that any tendency ofthe steam-faces of the chest and cylinder to wear unequally, and. thus cause leakage of steam and necessitate the renewal of the working parts of the chest and cyliuder, is in a great degree avoided, and at the same time the friction upon the trunnion is greatly reduced, as the weight of the cylinder is compensated for by the spring attached to it.
Having now set forth my presentinvention, what I claim as new is--- The combination of a spring, M, with the oscillating cylinder E, bent notched lever N, weight Q, and hook P, substantially as and for the purposes described.
EDWARD I. RYDER.
