.OLIVER COLBORNE,OF CHICAGO, ILLINOIS.
VERTICAL ANTI-FRICTION ENGINE.
SPECIFICATION forming part of Letters Patent No. 423,515, dated March 18, 1890.
Application led November, 1888. Renewed February 17, 1890. Serial No. 340i962. (No model.)
To all whom it may concern.-
Be it known that' I, OLIVER CoLBoENE, a
citizen' of the United States, residing at' Chience marked thereon, which form a part of this specification.
In the drawings, Figure 1 is a vertical sectional elevation of my improved engine through the center of thecylinders. Fig. 2 is an enlarged section of one of the anti-friction rollers. Fig.3 is the eccentric-with .one guide band o r ring left off to show the position of the anti-friction rollers. Fig. 4 is a' sectional elevation of the valve through the dotted line in Fig. l. Fig. is a cross-section of the valve through the dotted line in Fig. 4.-.
Like letters indicate like parts in the several views. i
My improved engine consists of a single casting forming'the base and united to the iianges B of the cylinders C C. The cylinders being cast in a single piece can be lifted 0E, allowing easy access to the shaft and eccentrics. The cylinders C C are provided .with long pistons D D', which are held firmly down on the loose ring c of the eccentric E by the steam, which is admitted only to their top sides or heads, as shown in the drawings, thus: The piston D of the cylinder C having completed its stroke, the valve. F will have been lifted by the eccentric H until the port e has been uncovered, admitting steam to the top of the piston D of the cylinder C, while, the port f ofy the cylinder C having been uncovered, the steam which has done its work will be exhausted into the annular space around the valve and out through the opening in the back side of the valve-casing. (Shown by the dotted-line circle marked g.)
v WVhenrthe piston D has completed its stroke,
the valve F will have been pushed down by the steam following the eccentric Huntil the vvalve has dropped below the port f. Steam coming in at the steam-pipe (shown by the dotted circle h) will enter the valve atz'z', passing up through vand over the top4 of the valve, and entering the steam-port f. lThe preponderance of pressure beingalways. on the top end of the valve keeps it in close contact with the eccentric H, which actuates it. In case of its use for large engines, where the friction would be considerable, this eccentric may be iitted with anti-friction rollers, the same as the large eccentrics E. The pistons D and D?, are by the steam held firmly in contact with the eccentrics, so that no lost motion on account Vof wear can affect them.
I am aware that eccentrics in place of cranks have been used on the shafts of steamengines as a means of converting the reciprocating movements of the piston into a rotary movement' of the shaft, and that disks rotating upon the rod connecting the pistons .of two cylinders and inclosing an eccentric upon the engine-shaft between them have been used. I do not therefore claim such an arrangement of parts, but limit my claim to the specific construction and arrangement of parts shown anddescribed, in which the pis.- tons ofthe different cylinders are not positively connected with eachother or with the eccentric, but are free to move independently of the eccentrics and of each other, `as described. y vHaving thus described my improved engine, what I claim as new, and desire to secure by Letters Patent, isl In a double vertical engine, the combination of the cylinders, the pistons resting directly upon but not connected to the antifriction rings encircling the eccentrics E, the eccentric Il, and the valve F, its lower end retained in contact with the periphery of the eccentric by the pressure of steam upon its upper end, all arranged for .joint operation substantially as shown and described.
In testimony whereof I affix my signature in presence of two witnesses.
. OLIVER COLBORNE.
