' VALVE-GEAR.
Specification of Letters Patent.
Patented Dec. 5, 1905.
Application inea March 21, 1905.v serial No. 251,294..
To all `whom it may concern: V
Be it known that I, WILLIAM P. HAsKIT'r, a citizenof the UnitedV States, residing at Gwynneville, in the countyof Shelby and State of Indiana, have invented vcertain new and useful Improvements in Valve-Gear for IIngines; and I do hereby declare the following to be a full, clear, vand exact description of the invention, such as will enable others skilled in the .art towhich it appertains to make and use the same.
My invention relatesl to valve-gear fo`r englnes, and more particularly to mechanlsm Y for reversing the valve.
The objectvof the invention is to provide a its operating-eccentric whereby the valve may 1 be shifted backward or forward without first interfering with the operation of the engine.
With the above` and other objects in view the invention consists of a power-shaft having an eccentric thereon, which is surrounded by and adapted to actuate an eccentric-ring, which in turn is surrounded by an eccentric-strap connected in the usual manner to the slidevalve of an engine. VBy shifting the eccentricvring the relation between the-strap and its operating-eccentric can be changed, thereby imparting movement to the slide-valve, so as to reverse the engine during the operation thereof. 4
The invention also consists of the further Y novel constructionsandcombinations of parts hereinafter more fully described, and pointed out in the claims.
In the accompanying drawings I have shown the preferred form of myinvention'.
In said drawings, Figure lis a view, partly in elevation and partly in section, of an engine having my improved valve-gear thereon. Fig. 2 is an elevation showing the eccentric and, its operating mechanism detached from the engine, the eccentric-ring being illustrated in a different position. from kthat shown in Fig. 1. This figure-also shows-in dotted lines another position to which the eccentric-ring vmay-be adjusted. Fig.v 3 `is a detail view of the eccentric-ring.
Referring to the figures by numerals of reference, 1 is aj power-shaft having a iiywheel 2, such as is ordinarily employed, and this 'shaft is adapted to be propelled in the usual manner by a piston 3, located in the engine-cylinder 4. An eccentric 5 is secured to and rotates with the shaft 1, and inclosingv this eccentric and slidably mounted upon it is an eccentric-ring 6, preferably formed of sections, which are held together upon opposite sides of the eccentric 5 by means of bolts or screws 7, extending through ears integral with this eccentric-ring is grooved to form a guidelway for a strap 9, which 1s secured 1n any -the sections of the ring. The periphery of preferred manner around the ring 6, and is r fastened to one end of a rod 10, which in turnis pivoted to a rodv 11, extending from the slide-valve 12 of the engine. An arm 13 is rigidly secured to ring 6 and pivoted to a link 514:, which in turn is pivotedto oneend of a pivoted supporting-bar 15.' A rod 16 is also pivoted tothis bar l5 and to an operating-lever 17, having means. for securing it in any position to which it may be adjusted.' l
It will be understood that by shifting lever 1 7 upon its fulcrum thewidest portion of ring 6 may be moved into position between the strap 9 and any portion of the periphery of eccentric 5. In other words, this portion of the ring can be shifted into any'desired relation to the horizontal plane extending through shaft 1. It will be understood that when the ring is in the position shown in Fig. 2 the distance between shaft land the sliding valve 12 is greater than when the ring 6 is in the position shown in Fig. 1. If therefore the engine is operating While the parts are in the positions shown in the first figure and it is dewhich may be transmitted thereto through the ordinary operation of the eccentric, and this movement will be suIicient to cause the reversal of the operation of the engine.
It will be. seen that the device is very sim-r,
IOO
ple and durable lin construction and dispenses Y with numerous and intricate parts which are liable to break or otherwise-get out oforder.
.Inthe foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be. made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.`
Having thus fully described my invention,
what I claim as new, and desire to secure by v Letters Patent, is-
1. The combination with an engine having a slide-valve; of a rotatable eccentric, a strap surrounding the eccentric and connected to the slide-valve, a ring of varying width interposed between the eccentric and the strap, means for manually rotating said ring independently of the movement of the eccentric and strap, and means for locking the ring in adjusted position.
2. The combination with an engine having a slide-valve; of means for reversing said engine comprising a rotatable eccentric, a strap surrounding the eccentric and connected to the slide-valve, a ring of varying width interposed between the eccentric and the strap, and means for manually rotating said ring independently of the movement of the eccentric and strap for shifting the valve to reverse the engine.
3. The combination with an engine having a slide-valve; of means for reversing said engine comprisinga rotatable eccentric, the strap surrounding the eccentric and connected to the slide-valve, a ring of varying width interposed between the eccentric and the strap, an arm extending from the ring, an operatinglever, connecting devices secured to the arm and lever, and means for locking the lever in any position to which it may be adjusted.
In testimony whereof I have signed my name to this specification in the presence of two subl scribing witnesses.
WILLIAM P. HASKITT.
