GOVERNOR.
SPECIFICATION forming part of Letters Patent No. 343,683, dated June 15, 1886.
Application filed April 17. 1886. Serial No. 199,209.
To allwhom it may concern.-
Be it known that 1, WILLIAM HNVHEELER, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Governors, of which the following is a full, clear, and exact description.
This invention relates to that class of governors which are applied directly to a flywheel, provided with a shifting eccentric to vary the throw or stroke of the valve-stem commensurately with the rapidity of revolution of the fly-wheel, and so automatically control the machinery driven.
Theinvention consists in the eccentric-shifting devices, as hereinafter particularly set forth and claimed.
In the accompanying drawings, in the several figures of which like parts are similarly designated,Figure1 is a front elevation; Fig. 2, a rear elevation showing also a modification of the arrangement of the springs, and Fig. 3 is a vertical section.
The drawings show a governor constructed for a vertical or horizontal engine, though obviously the invention is not so limited.
The fiy-wheel a is of ordinary construction. I) is the shaft to which it is keyed or otherwise affixed. c is a yoke, rectangular in outline, and having on opposite sides inclines d of reverse inclination, the said yoke inclosing the shaft and having a rectilinear movement on a squared boss, 6, of a guide-plate, f, for the shifting eccentric g. The guide-plate fhas .upon its face, at right angles to the length of the yoke, certain groo\-*es,h,which engage parallel ribs 2' on the back of the eccentric g, and said eccentric is provided With beveled or inclined lugs j, projecting from its rear face through openings 7c in the guide-plate f, and matching and engaging the inclinesd d on the yoke 0, so that the movement of the yoke is transmitted to the said eccentric, and as said yoke is shifted the eccentric is correspondingly operated. The opening Z in the eccentric for the shaft 12 is elongated in the direction of the movement or shift of the cocentric, as will obviously be necessary to permit such movement. The yoke is shifted by centrifugal levers, m a, pivoted respectively at 0 and p to the spokes of the wheel a. The
(No model.)
lever m is provided with an elbow extension, in, from its pivoted end, and this is connected bya link, q, to an elbow-lever, r, pivoted at s to a spoke next the pivotal spoke of the lever m,the pivots of the two being on substantially the same chord drawn through the wheel or at equal distances from the center of the wheel.
The elbow-lever 1" is connected by a jointed link, It, to one end of the yoke. The lever n has an extension, or, connected by ajointed link, t, to the opposite end of the yoke. Each leveris provided with the customary speedweights to upon its free end, and is further restrained by a coiled spring, o, connected by one end to one lever,and swiveled at its other end to the spoke to which the opposite lever is pivoted, so that said springs draw evenly upon the levers. As indicated in Fig. 2 the springs might connect the opposite levers. The introduction of the elbow-leverr and link q not only takes the place of a dashpot or equivalent device heretofore employed, but
serves to permit the proper arrangement of the levers with respect to the eccentric shifting medium, and insures against any binding of the parts, thus being,in fact,a positive motion. It will be seen that as the levers fly off from the center of the wheel, they both assist in moving theyoke in the same direction, and hence effect the shifting of the eccentric. The springs make the return movement when the centrifugal forceis relieved or removed.
What I claim' is- 1. In a governor, a fiy-wheel, a yoke provided with inclines, and weighted springlevers pivoted to said fiy-wheel and connected to the yoke to shift it with the change in speed of the machinery, and a shifting eccentric engaging said yoke and shifted by it, substantially as described.
2. In a governor, a fly-wheel, a shifting yoke, 0, provided with oppositely-inclined sides, (1, d, a guide-plate, f, connected by a squared boss therewith, and a shifting eccentric movable in ways on said guide-plate and provided with beveled or inclined lugs engaging said yoke, combined with centrifugal levers pivoted to said fly-wheel,and connected to opposite ends of the yoke, substantially as described.
3. In a governor, a fly-wheel, a shifting yoke, 0, provided with oppositely-inclined ICO sides, (I d, a guide-plate, f, connected by a squarcdboss therewith,andashifting eccentric movable in ways on said guide-plate and pro vided with beveled or inclined lugs engaging ssaid yoke, combined with centrifugal levers and weights pivoted to said fly-wheel to move said eccentric, and an elbow-lever, r, and link q, interposed between one of said levers and the yoke, substantially as described.
4. In a governor,ashifting mechanism comprising the yoke and its inclined sides,the carrier or guide plate having ways for the cocentric at right angles to the yoke,and the occentric mounted upon said plate and having inclined lugs extending through the plate and engaging the. inclined sides of the yoke, the centrifugal counter-weighted levers pivoted to the fly-wheel and connected together by springs, and the link t,elbow-lcver 9*,and link q, connecting one end of the yoke and one of 20
