ROY C. KIMBLE, OF VICKSBURG, MICHIGAN.
SPEED-REGULATING DEVICE ENGINE-GOVERNORS.
SPECIFICATION forming part of Letters Patent No. 720,934, dated February 17, 1903.
Application filed February 18,1902. Serial No. 94,662. (No model.)
To all whont it may concern: I
Be it known that I, ROY O. KIMBLE, a citizen of the United States, residing at the village of Vicksburg, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in Speed- Regulating Devices for Engine-Governors, of which the following is a specification.
This invention relates to improvements in speed-regulating devices for engine-governors. It is particularly adapted for use as a speed-regulating device in connection with engine-governors of the class described in United States Letters Patent No. 654,007, issued to James E. Kimball July 17, 1900, although by proper structural variations it may be applied to I any engine governor which throttles the steam.
The object of my invention is to provide an improved speed-regulatin g device for governors which is simple in its construction and operation.
A further object is to provide an improved speed-regulating device capable of accurate and quick adjustment and which may be adjusted while the engine is in operation.
Still further objects will definitely appear in the detailed description to follow.
Iaccomplish the objects of my invention by the devices and means described in the following specification.
The invention is clearly defined and pointed out in the claims.
A structure embodying the features of my invention is fully illustrated in the accompanying drawings, forming a part of this specification, in which- Figure l is a detail side elevation view ofa structure embodying the features of my invention. Fig. 2 is an enlarged detail longitudinal sectional view taken on a line corresponding to line 2 2 of Fig. 1. Fig. 3 is a de tail cross-sectional view taken on a line cor responding to line 3 3 of Fig. 2. Fig. 4 is a detail sectional view taken on a line 4 4 of Fig. 1. Fig. 5 is a detail longitudinal sec-- tional view ofa modification of the view corresponding to that shown in Fig. 2. Fig. 6 is a detail view taken on line 6 6 of Fig. 5.
In the drawings all of the sectional views are taken looking in the direction of the little arrows at the ends of the sectional lines, and
"carried by and keyed to the shaft G, the shaft G being supported in suitable hearings in the brackets B B on the frame B and the arm or lever F pivoted on the said shaft G. The arm E is adapted to engage the head D on the rod D, while the arm F engages the head 0 on the rod 0. These levers or arms project at E F, and a thumb-screw at is provided by means of which the relative position of the arms E and F is accurately controlled, and the length of the valve-stem may be increased or diminished according' as is desired to decrease or increase the speed of the engine, it being apparentthat the longer the valve-stem the less the motion required of the governorballs to close the valve. A coiled spring G is provided on the shaft G, which engages the lever or arm F to put proper. tension on the valve. This tension may be accurately adjusted by means of the ratchet-wheel H and the pin 0.
In the modified structure shown in Figs. 5 and 6 the arms 6 and f are supported on separate pivots or shafts r and G, brackets it bein g provided to support the same. A thumbscrew 02., through the projecting ends ef', is provided by means of which the relative position of the arms 6 f may be adjusted to regulate the length of the valve-stem, and thus accurately control the speed. The adj ustment and operation are substantially the same as those of the preferred structure.
It is evident that the adjustmentsmay be made while the engine is in motion and that the same is under complete controlof the operator. The spring G not only serves to put proper tension on the valve, but also serves to remove any slack motion that may result through the connections.
I have illustrated and described my imthe form preferred by me. I am aware, however, that other modifications than that illustrated will readily appear to those skilled in the art to which my invention appertains without departing from my invention.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a speed-regulating device for enginegovernors, the combination of a suitable governor-valve; a valve-stem divided in two parts 0 and D; a shaft G; an arm or lever E secured to said shaft engaging the upper part D of the valve-stem; an arm or lever F pivoted on said shaft, engaging the part 0 of the valve-stem; a spring G on said shaft engaging said lever F and arranged to put tension on the same; means for adjusting said spring; and a thumb-screw through the projecting end of one of said arms and adapted to engage the other, whereby the relative position of said arms is controlled, all coacting for the purpose specified.
2. In a speed-regulating device for enginegovernors, the combination of a suitable governor-valve; a valve-stem divided into two parts 0 and D; a shaft G; an arm or lever E secured to said shaft, engaging the upper part D of the valve-stem; an arm or lever F pivoted on said shaft, engaging the part 0 of the valve-stem; a spring G on said shaft engaging the said leverF; means for adjusting said spring; and means of adjusting said arms in relation to each other whereby the length of the valve-stem is controlled, all coaoting for the purpose specified.
3. In a speed-regulating device for steamengine. governors, the combination of a suitable valve With a governor; a divided valvestem; a connection for said parts consisting of a pair of arms, or levers, suitably supported, each lever engaging a part of the said valve-stem; and means by which said levers may be adjusted in their relations to each other to change the relative position of the parts of the valve-stem to regulate the length thereof, for the purpose specified.
In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.
