CHARLES J. KOCH, OF BIGSTONE, SOUTH DAKOTA.

GOVERNOR-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 748,751, dated January 5, 1904.

7 Application filed May 8. 1903. Serial No. 156,233. (No model.)

To all whom it may concern:

Be it known that I, CHARLES J. Koon, a citizen of the United States, residing at Bigstone, in the county of Grant, State of South Dakota, have invented certainnew and useful Improvements in Governor-Regulators; and I do hereby declare the following to'be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. v a

This invention relatesto engine-governors; and it has for its object to provide a regulating mechanism which may be easily and quickly operated to adjust the governor to permit of a higher or lower speed of the engine and which adjusting mechanism itself may be adjusted so that diiferent positions of the operating-lever may give the same speed of the engine under difierent loads.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure l. is an elevation showing a governor mechanism equipped with the present invention. Fig. 2 is a transverse section through the guide-bracket of the governor mechanism in a vertical plane.

Referring now to the drawings, there is shown a governor comprising the valve 5, from which projects the valve-stem 6, which is connected with the spindle 7 of the governor, said valve-stem being forced'downwardly as the ballast-balls fly outwardly and raise as theballs return. The governor is driven by means of a pulley 8, fixed to a shaft 9 and carrying a bevel-gear 10, which works in a corresponding bevel-gear 11 on the governor, so that rotation of said shaft will rotate the spindle and the balls.

Mounted transversely above the valve 5 is a shaft 12, on which is loosely mounted a sleeve 13, having an arm 14, which is bifurcated, so that it may receive the valve-stem between the collars 15, which are fixed on the stem, so that when the stem moves vertically the arm will be operated to oscillate the shaft through the medium of the helical spring 16, which is mounted upon the shaft and is fixed at one end to the shaft and at its opposite end to the sleeve. If then the shaft is held stationary, the upward movement of the arm,

with the valve-stem, will tend to wind the helical spring and place it under tension. Conversely, if the shaft is rotated in the proper direction the spring will be placed under tension, so as to cause the arm to press the valvestem downwardly and resist upward move ment of the valve-stem, so' that a greater speed of rotation of the balls will be required to cause them to fly outwardly and raise the valve-stem to a given extent, so that the engine may run at a higher rate of speed.

To rotate the shaft and adjust the tension of the helical springs, a pinion 17 is attached to the shaft, and engaged therewith'is a rackbar 18, so that when the rack-bar is reciprocated the pinion will be oscillated to change the tension of the spring.

From the rack-bar leads a rod 19, which is screwed into a turnbuckle 20 and has a jamnut 21 to prevent rotationof the turnbuckle on the rod. With the turnbuckle is engaged asecond threaded rod 22, which is connected to a hand-lever 23. Adjacent to the handlever is a notched segment 24, and a handlever is provided with a latch 25 for engagement with the notched segment to hold the lever at different points of its adjustment wit the helical spring under difierent tensions. With this construction it will be understood that by shifting the hand-lever the rack-bar will cause the pinion to rotate and wind up or unwind the helical spring, so that the arm will press to a greater or see degree upon the valve-stem. When the same speed of the engine is to be obtained at corresponding positions of the hand-lever, but under different loads, the length of the rod may be changed by means of the turnbuckle. Thus when the engine is working under a difierent load the mechanism may be so adjusted that with the hand-lever at the limit of its movement the same speed of the engine will be obtained as with a greater or a lesser load.

The rod 19 is formed in two sections, as illustrated, said sections being pivoted to the ears 26 and 27 of a V-shaped upright 28, the lower ends of which are fixed to a rock-shaft 29. This arrangement permits of bending the rod, so that it will work'freely around a corner. 7

What is claimed is-- o with the rocker, a second rod connected to the rocker, a third rod connected to the handlever, and an adjusting-turnbuckle engaged with the free ends of the second and third rod.

In testimony whereof I affix my signature in presence of two witnesses.
