IMPROVEMENT IN THREE-CYLINDER ENGINES.
Specification forming part of Letters Patent No. 14%',5999 dated February 17,1874; application filed December 20,1873.
To all whom it may concern Beit known that I, PHILIP T. BRowNELI., of Elmira, in the county of Ghemung and State of New York, have invented a new and useful Improvement in Three-Cylinder Engines, of which the following is a specification Figure l is a detail section of a three-cylinder engine, taken through the line w Fig. 2, illustrating my improvements. Fig. 2 is a detail section of the same, taken through the lino y y, Fig. l. Fig. 3 is a side view of the bush before being cut into sections. Fig. 4t is an end view of the same after being cut into sections.
Similar letters oi reference indicate corresponding parts. A
My invention has for its object to furnish an improved bushing for the crank-pin of a threecylinder engine, and an improved oiling device for the same, which shall be simple in construction and reliable in operation. The invention consists in a sectional bush for the wrist or crank pin of the engine, and in a lubricating device attached to said wristpin, and revolving' with it, as hereinafter described.
A represents the steam-drum, and B the three cylinders, of the engine. C are the three pistons, and D are the piston-rods. Upon the inner ends ofthe piston-rods D are formed eyes, through which the crank-pin E passes, which eyes are made larger than the said crank-pin, to give space for the bushing. F-
is the bushing, which is turned up much heavier than for ordinary use, and the outside of which may be left smooth, or may be grooved to receive the eyes of the rods D. The turned plane or grooved cylinder is then cut longitudinally into four equal parts, which are arranged around the crank-pin E, within the eyes of the radial sliding rods D, and are secured to said eyes, one to each,l in such positions ,as to give the proper bearing upon the pin. The inner surface of the eyes of the rods D are so formed as to permit a free movement over the parts of the bush that are fastened to the other eyes; or the bushsections may be dressed down in the parts that the eyes move over. The shaft H has a disk, G, attached `to its inner end, (a radial arm would answer the same purpose,) and the wrist-pin E projects therefrom in a plane eccentric, but parallel to said shaft. Thus at each revolution the pin E describes a circle, whose center is the axis of the shaft. The oil for lubricating the bearings or bushings is held in and supplied from a cup, I, which is attached xedly to the pin Elby any suitable means, but is arranged eccentrically thereto, and concentrically with shaft H. Said cup is essentially in the form of a hollow truncated cone, and its base vertical, z'. e., parallel to the disk G. A supply-tube, J, passes through the side of the drum, and is curved at its inner end to deliver the oil into the cup.. A small aperture is made through the base of the cup, beside the pin E, through which the oil passes to the bearings, 85o. It will be seen that by this ar rangement the cup I has two rotary movements-one on itself around the pin E, and another around a center which would be the axis of the shaft H if extended.
Vhen the engine is at rest, the oil remains in the lower portion of the cup. When in motion, the oil is distributed in the cup, and carried around by centrifugal force, finding its way to the bearings.
A supplemental wrist-pin, having arm K, may be attached to the center of the cup I, t'. e., concentric with shaft H and disk G, for the purpose of operating the rotary valve of the engine.
Having thus described my invention, I claim as new and desire to secure by Letters Pat entl. The sectional bush F, in combination with the eyes of two or more radial sliding rods, D, and with a pin, E, when two orI more eyes work upon the same pin, substantially as herein shown and described.
2. The combination of the oil-cup I and oilinduction tube J with the pin E, bushing F, and rods D, and with the steam-drum A of a three-cylinder engine, substantially as herein shown and described.
PHILIP T. BROWNELL.
