DEVIGE FOR GQNVEBTING MOTION.

WILLIAM H. WOOD, OF HARTFORD, CONNECTICUT.
DEVICE FOR CONVERTING MOTION.
SPECIFICATION forming part of Letters Patent No 349,775, dated September 28, 1886.
Application tiled March 12, 1886. Serial No.'194,983. (No model) 4 T0 aZZ whom, it may concern.-
Be it known that 1, WILLIAM H. W001), of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Devices for Oonverting Motion, ofwhich the following is a description, reference being had to the accompanying drawings, and to the letters of reference marked thereon, where Figurel is a detail view, in central longitudinal section, of one of a group of cylinders, of part of the hollow shaft, and of the cams of an engine embodying my invention. Fig. 2 is an end view of the cylinder-head of a group of cylinders, showing the cylindrical supports 1 0313116 cross-heads and the ends of the pistonro s.
The object of my invention is to provide, in an engine in which the use of a crank is avoided, such a combination of curved cams and the piston-rods as will overcome the difficulties existing in the form of curved cam-grooves in the engine described and claimed in my application for United States Letters Patent, Serial No. 171,871.
My invention consists in the combination of a cylinder with a piston-rod extending through both heads thereof, and each bearing against the faces of similar cams that are both fast to a rotary shaft, and in details of the parts, as more particularly hereinafter described and claimed.
So much only of the complete engine is shown as is necessary to the present invention,
the Valve and its connected parts and the rotary shaft being broken away in the accompanying drawings.
In the accompanying drawings, the letter a denotes the cylinder of an engine that is operated by the expansion of vapor, as steam, carbonic acid, or the like gas; I) and b, the steam-ports at opposite ends of the cylinder; 0 and d, the cylinder-heads; e, the piston: f, the piston-rod that extends from both sides of the piston through the piston-heads, the openings through the'latter being packed in the usual manner. Fast to the cylinder-heads are the ways 0 d, that are preferably so connected laterally as to form a continuous web that resembles two open-ended cylinders projecting from the cylinder-heads, and in the walls of each are formed the grooves into which the ends of the cross heads project. The crosshead a bears in line with the axis of the piston-rod a roller, 0 and the shaft of this roller extends each way from the cross-head, and bears on each side a roller, 0', that fits in the channel between the guides or ways and serves to reduce the friction due to the lateral thrust or reaction of the cam g, against the face of which the roller 0 directly'bears. This cam g is formed on the edge of acylindrieal camblock, 9, that is held on the shaft h, between the set-nuts h it, that fit upon a thread cut in the shaft. The cam-block is hollowed out so that its outer wall projects between the open ended cylinders in which are formed the ways for the cross-head bearing. On the opposite end of the piston-rod is fast the cross-head bearing the rollers 11 and d", which are arranged precisely similar. to the rollers upon the opposite end of the piston-rod, as already described, and the roller (1 bears against the edge of the cam '5, formed on the edge of the camblock 1', which are the counterparts of the cam and cam-block already described. This latter cam-block, t, is adjustably secured to the shaft it between set-nuts, so as to 'render it longitudinally adjustable, as in the case with the other cam-block. These cams are so secured to the shaft it that the distance between the adjacent faces of the cams g and i when they are in a line parallel to the axis of the shaft is always the same, and the thrust of the piston-rods comes directly upon the cam of each cam-block, and in line with the axis of the piston. The advantage gained by this construction is, that the movement of the rollers along each of the cams 'iscontinuous and in the same direction, whereas/in the form and arrangement of the cam-groove and the en gaging-pin on the piston-rod in old devices the roller reverses its rotary motion at the end of every stroke.
Another advantage is \in the adjnstability of the cam-blocks, by which any wear 'is-taken up so as to prevent endwise play of the piston between the cams, and thisfeature is a further improvement over old devices.
In Fig. 2 the end view of a cylinder-head appurtenant to a group of six cylinders, is shown, the lateral position of the cam being shownin dotted outlines.
I claim as my invention- ICO 3. In combination, the fixed cylinder, the rotary shaft bearing the inward-facing curved cams at all points equidistant from each other, and the double-ended piston-rod located between the cams and parallel to the shaft and bearing with its opposite ends directly against the similar cams, all substantially as de- 20 scribed.
