' PENDULIUM on VlBRATiNG-PISTON ENGINE.
SPECIFICATION forming part of Letters Patent No. 367,872, dated August 9, 1887. Application filed September-15, 1886. Serial No. 213,608. (No model.)
To all whom it may concern.-
Be it known that L'JULIUs' WM; "WALTERS, a citizen of the United States, residing at New York, in the State of New York, have invented certain new and useful Improvements in Pendulum or Vibrating-Piston 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 towhich itappertains to make and use the same.
My invention relates to improvements. in that class of engines usually called pendulum or vibrating enginesi. 6., in which a vibrating piston is secured upon an oscillating shaft and operates in a sector-shaped chamber, whose diverging walls radiate from the shaft of the piston.
.The object of my invention is to improve this, style of engine, and to produce a very simple, economical, effective, and compact engine, which can beused either as a simple or a compound engine-that is, the steam is first utilized in a high-pressure cylinder or chamber of smaller size, and thentin a low-pressure or expansion cylinder of larger size; also, to exhaust the steam from the high-pressure eylinder into a receiver, (inclosing said cylinder and forming a j acket,) and thence passingit to the low-pressurecylinder; or the steam from the receiver can be utilized by mixing it with the live steam from the boiler by means of an injector placed in the side of the inlet-pipe leadinginto the high-pressure cylinder. Furthermore, to produce an engine that is readily accessible to all its parts, and'can be run at high velocities,and,finally,large power can be obtained in proportion to the quantity of fuel consumed.
My invention consists in arranging the high and low pressure cylinders of a compound engine side by side, and connecting the pistons of each engine by suitableconnecting-rods to acommon crank-shaft having its cranks placed at an angle of ninety degrees, or at right augles to each other; also, in combining with each engined vibrating piston with or Without a balanced v, lve and suitable inlet and exhaust ports; also, i l placing the valve-gear between the engines a d the starting-gear on theoutside thereof; also, in placing a'receiver on each engine for the exhanststeam, acting as steam-jackets, and these cast with the frame, so as'to inclose'the cylinders,valve, and ports; also, in attaching an injector in the sideof the receiver, so that part or all of the steam contained in said receiver may be utilized by mixing it with the steam from theboiler in said cylinder by means of said injector forcing it into the cylinder from the receiver, and, finally,in the construction and arrangement of details, more fully described hereinafter, and specifically pointed out in the claims, reference being had to the accompanying drawings and the letters of reference thereon.
Like letters indicate similar parts in the different figures of the drawings, in which Figure 1 represents a side elevation of the high-pressure cylinder and valvegear.
der and its valve-gear. Fig. 3 is a vertical transverse section of the higlrpressnre cylinder. Fig. 4 is a similar View of the low-press- 'ure cylinder. Fig. 5 represents a longitudinal verticalsection of the high and low pressure cylinders connected to the crankshaft.
In said drawings, A is a suitable bed-plate, upon which the frame or casing B isv mounted and secured, which frame contains the cylinder, valvechamber, valve, ports, receiver, and pillow-blocks for the crank-shaft. Said casing is provided with the removable heads or bonnets B B. In the upper part of the casing is .formed the Steamehest, in which an oscillating or rocking valve, G,-operates, and admits and exhausts the steam to and from the cylinder D through the inlet and outlet ports b c. The cylinder is of sector shape, and its ends or diverging walls radiate from the shaft d, to which the piston E is secured or cast, and it vibrates in said cylinder. lhe piston should be provided with packing in its sides and periphery, set out by springs or steam admitted through small holes 6 (see Fig. 5) in' the body of the piston, as desired. The shaft (2 is journaled in the sides of the casing in proper bearings, and extends through packing 1) on one side, and it has an arm, F, se-
cured to it, which has a pin, f, to which the connecting-rod P (represented in full in Fig. 5 and, by a broken line, :0, in Fig. 1) is attached with one end, while the opposite end Fig. 2 is a similar view of the low-pressnre cylinis connected to the crank-pin g of the crank G on the crank-shaft II. The packing p, of segmental or other kind, serves to prevent leakage around the shaft (1, and when it commences to wear or needs adjusting or setting up it is forced inward by a suitable spring, q, placed behind the gland p. The hub of the arm N is bored out to receive the packing, and is secured to the shaft m by one or more setscrews. It is also titted over the nipple or reduced end qof the bearing at that end for said shaft. The packing is thus self adjusting.
The cylinder, steam-chest, valve, and ports are inelosed in a receiver, It, into which the exhauststeam from the cylinder I) is exhausted, and thence it passes through a pipe, 2, into the low-pressure cylinder L, where it exerts its force by expansion on the piston contained therein. Auynumber ofexpansioncylinders may be employed to expand the steam as often as it is desired. A stop-valve, i, may be placed in the pipe 'i when the highpressnre cylinder only is to be used or the englue is to act as an ordinary direct-acting engine, and the exhauststeain may then be led to a condenser or to the atmosphere.
In the side of the casing and communicating with the steam-inlet pipe a is arranged an injecting-valve, I, communicating by a pipe i with the live steam in the boiler, by which means the steam in said receiver can be utilized and mixed with the live steam before entering the cylinder D. The crank-shaft II is journaled in bearings .I, formed partly .in the bed-plate and partly in the bottom of the easing B, and the cap is provided with an oil-cup for lubricating the shaft :r. The journal-boxes may be lined and adjusted by keys, bolts, or otherwise.
The steam having exerted its power on the piston of the high-pressure cylinder, is exhausted into the receiver R and passes through' the pipe 17 into the valve-chamber of thevalve K of the low-pressure cylinder, and thence through suitable inlet and exhaust ports cf into the cylinder L of larger size, containing the piston M, secured to the shaft 121, and jour naled in similar manner to the shaft (1. The cylinder L is provided with heads L L, and is inelosed in a receiver, B. An arm, N, with pin a, is secured on the end of the shaft on, and to said pin the connecting-rod I is attached with one end,while the other end is connected to the crank-pin 0 of the crank O.
The valve-gear V, (shown in Figs. 1, 2, and 5,) preferably of the link kind, is placed be tween the two engines and by suitable valverods and arms operates the valves. The start ing-gear S is placed on the outside of thehighpressure cylinder so as to be more accessible. \Vherever it is required or deemed necessary at any of the joints, and there is liability of leakage, suitable packing must he provided. The exhaust from the expansion or low-pressure cylinder passes into the receiver R, and thence through the nozzle 1 into the condenser or the atmosphere.
The engines can be made of any suitable size required, and the different parts may be made of any suitable material, and various changes in the details of construction may be made without departing from the scope of my invention. The engine may be also employed as an air-compressor, in which case it is only necessary to reverse the action of the valves, so as to receive through the exhaust-pipe and exhaust through the inlet-pipe, the air being taken into the low pressure cylinder and forced into the high-pressure cylinder,in which the air is further compressed.
Thisengine is especially adapted for launches, steam-yachts, and for other pu rposcs requiring engines running at high speed or velocity. The cylinder, steam-chest, receiver, pillow-blocks, and frame or casing may be cast in one piece, if desired, and the piston-shaft may be extended through both cylinders and the pistons secured thereon, although I prefer to make them independently and cast thepistons on them.
Having thus described my invcntion,what I. claim, and desire to secure by Letters Patent, 1s-
