.'osclLLATlNG-ENGINE.
SPECIFICATION forming" part of `Letters Patent No. 224,093, dated February 3, 1880.
l Application led December 31, 1879.
To all whom t may concern Be itknown that I, JoHN F. KINGsLELof Owego, in the county of Tioga. and State of New York, have invented a new and valuable Improvement in Oscillating Engines; and I do hereby declare that the following` is a full, clear, and exact description of' the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and gures of reference marked thereon.
Figure 1 of the drawings is arepresentation of a side elevation of my improved engine without the frame. the same, partly in section. Fig. 3 is a detail view ofthe eccentric with forked end.
The object of the presentinvention is to improve the construction and operation of oscillating engines; and it consists `in a peculiar valve-gear adapted to oscillating engines, by which the action of the valve is not materially aii'ected,a1`1d by which it canbe `set to have more or less lap and lead, and also to out off at longer or shorter stroke, all of which will be more definitely described hereinafter, and s'nb` seqnently pointed ont in the claims.
In the accompanying drawings, A represents the cylinder of an oscillating engine of the ordinary construction, and providedwith stuffing-box and piston-rod. The cylinder A has also a steam-chest, c, and slide-valve 4b, also of the usual construction, and on each side the trunnions B B. V
The trunnion B is provided with a square shoulder, C, upon which an auxiliary eccentric, D, moves up and down. i
The eccentric D has a rectangular opening, d, in it to allow of such movement, `and is held in position laterally upon the trunnion by guide-pieces c c.
The eccentric-strap E has a rod, e, which extends to a movableor stationary point at right angles or in linewith the center of the cylinder and center of crank-shaft; but, for convenience, in this case it has a forked end, e, to receive the crank-shaft, on which it is free to slide on a line with the center of cylinder and center of shaft.
An adjustable collar, d', on the shaft S pre- 'vents lateral motion of the forked or upper end of the rod e upon the shaft. 'Io the side of Fig. 2 is a front elevation of the rod is pivoted a rod, j', of the main eccentric-strap F, that revolves on the main-eccentric G, and is provided with the ordinary lugs and bolts for holding it in place thereon.
The eccentric D has a hub, H, extended on the side toward the valve-chest a, which is also provided with a rectangular opening to allow it to move on the square part of the trunnion.
To this hub is secuied an arm, h, bent at right angles, or nearly so, at its upper end, and is provided with a suitable hole for the reception of the end of the valve-stem I, which is connected in the ordinary manner to the valve b.
The piston-rod terminates in the usual stub end andbrevolves upon the crank-pin 7c, preferably arranged between the two crank-plates K, by which a steadier motion is obtained than by a single crank.
The operation is as follows: The eccentric D having been placed in its proper position on the trunnion B, and the main eccentric Gr arranged on the shaft S, the two rods are connected, as shown at Z.
-If it isdesired at any time to alter lap and lead of the valve, the eccentric Gris merely set eitherforward or backward in the ordinary manner on the shaft S, by Which the valve obtains the proper movementthrough the medium of the bent arm h. The valve can also be adjusted by the nuts n n on the valve-stein.
The great advantages of my improvement are, that a very great steadiness is imparted to the valve-stem and the eccentric-rods instead of the usual knuckle-joint. It is also very simple in its construction and operation.
The parts of the engine constructed inl ac cordance with-my invention are not` liable to get out of order, and can be easily repaired or" replaced when found necessary. The valve can be very easily adjusted to any desired point to cut oft' shorter or longer, and sijinply by giving more or less lap and lead to it.
Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. In an oscillating engine, the auxiliary eccentric D, provided With. hub H, slot d, and bent arm h, in combination with the valvestem I and the main eccentric G, the whole constructed and arranged to operate substantially as and for the purpose set forth.
