To all whom it may concern:

Be it known that 1, JOHN E. MoDANmL, a citizen of the United States, residing at Madison Mills, in the county of Fayette, State of Ohio, have invented certain new and useful the governor balls including the supporting framework thereof as a whole at 14, these parts being of the usual construction.

Attached to the frame 11 at one side is a bracket 15 and attached to the frame 11 at the opposite side is a similar bracket 16, the brackets supporting a shaft 17 which extends transversely of the frame 11 and is spaced therefrom as shown. The shaft 17 is provided with a laterally extending forked member 18 which bears upon opposite sides of the rod 13 and engages between spaced collars 1920, so that the rocking or oscillation of the shaft 17 will cause the rod 13 to be moved upwardly and downwardly as hereafter explained.

Connected centrally thereof to the shaft 17 is an arm 21, and formed upon the bracket 16 is a rigid arm 22, and connected respectively at one end to the arm 22 at its ends shaft having connectin means whereby the are springs 23-24, the opposite ends of the rocking of the shaft will change the position springs being connected to the arm 21 above of the valve rod of the governor, an arm conand below the shaft 17 so that the springs nected to the rock shaft, and yieldable means operate to hold the arm 21 yieldably in a coupled to the arm whereby the rock shaft vertical position, the object to be hereafter may be adjusted and yieldably supported to 1 ex lained. change the position of the valve rod of the governor, and thus regulate the speed of the engine.

The invention further consists in certain novelfeatures of construction as hereafter shown and described, and then specifically ointed out in the claim, and in the drawings illustrating the preferred embodiment of the invention, Figure 1 is a view from one side of a conventional steam engine overnor with the improved device app ied. Fig. 2 is a view of the parts shown in Fig. 1 from another side. Fig. 3 is a plan view in section on the line 33 of Fig. 2. Fig. 4 is a perspective view of the valve rod and a por- Improvements in Steam-Governor Attachments; 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.

This invention relates to steam governors, and has for its object to provide a simply constructed attachment whereby the speed of the engine may be increased or decreased by manipulating the valve rod of the governor.

With these and other objects in view the invention consists in brackets adapted to be attached to the frame of a governor, a rock bonnected to some stationary portion of the engine, as for instance to the steam chest indicated at 25, is a toothed segment 26 upon which a lever 27 is pivoted at 28 near one end, the lever being provided with a spring actuated pawl 29 engaging in the teeth of the member 26 and actuated by a hand grip 30 of the usual form. By this means the lever may be adjusted to any required point relative to the toothed segment and locked thereto as required. Connected between the upper end of the arm 21 and the lever 27 above its pivot 28 is a yieldable member formed with a section of spring 31 and a rod 32, and likewise contion of the shipper mechanism. nected between the lower end of the arm 21 The improved device may be applied withand the lower end of the lever 27 is a yieldout material structural changes to steam enable member formed of a section of spring 33 gine governors of various forms and conand a rod 34. By this arrangement a rockstructions, and it is not desired therefore to ing motion may be imparted to the rod 32 by limit the invention in its operation to any the movement of the lever 27, the adjust specific form of governor, and for the purment of the arm 21 thus corresponding to the pose of illustration the im roved device is adjustment of the lever, the springs 3133 shown applied to a conventional governor in permitting the arm 21 to be oscillated indewhich the base or valve chamber is reprependently of the lever to a limited extent so sented at 10,the arching frame supporting the that the rod 13 may be moved vertically valve rod at 1 1, the gearingwhereby the valve rod is rotated at 12, the valve rod at 13 and '14 independently of the position of the lever l through the influence of the ball mechanism 27 owing to the yieldable nature of the springs 2324 and 3l-33, while at the same time by adjusting the lever 27 the position of the rod 13 relative to the valve 35 in the easing 10 may be changed to enable the speed of the engine to be correspondingly changed, as hereafter explained.

By setting the lever 27 in a vertical position the arm 21 will likewise be dis osed in a vertical position and the arm 16 isposed in a horizontal position or at its intermediate adjustment, so that the movement of the rod under the influence of the governor balls will be normal, and when the parts are left in this position the speed of the engine will be controlled in the ordinary manner. If however, the speed is to be increased the lever 27 will be adjusted to elevate the arm 16 which will correspondingly elevate the rod 13 and open the governor valve 35 thus permitting more steam to pass to the governor, and this adjustment of the rod 13 does not affect the operation of the governor which still continues to control the speed at the new rate, and if'the speed is to be reduced below the normal the lever 27 is adjusted in the opposite direction to cause the arm 21 to rotate the shaft 17 and depress the arm 16 and thus correspondingly depress the rod 13 and close the governor valve to a corresponding extent and thus permit a less quantity of steam to pass and correspondingly reducing the speed, the governor continuing then to control the speed in the same manner.

By providing a plurality of the notches in the segment 26 it will be obvious that the position of the lever may be adjusted to any required extent and thus provide for any required speed of the engine.

The speed of the engine may thus be easily controlled without reference to the throttle j valve, and controlled'in a much'more accurate manner. r

The adjustments may be very delicately made and very slight differences in speed produced.

The improved device is simple in construction, can be readily ap lied to governors of various forms and sizes by making slight and immaterial changes in the forms of the brackets 1516 to adapt them tothe differences in the forms of the frames of the governors, and as these slight changes do not affect the construction of the device it is not deemed necessary to illustrate the various forms of brackets necessary to be employed.

What is claimed, is

The combination with a steam engine overnor, including a valve casing, the va ve, the valve rod, the means for automatically controlling the position of the valve rod, and a frame for supporting the valve rod controlling means, of brackets spaced apart and connected to said frame, one of said brackets having oppositely extending rigid arms, a shaft mounted for oscillation in said brackets, coupling means between said shaft and the valve rod, an arm connected to said shaft and partaking of its motion, springs connected between the arm of said shaft and the rigid bracket arms at opposite sides of the shaft, a swinging lever, means for locking said lever in any required position, and yieldable coupling means between said lever at opposite sides of its pivot and the arm connected to said shaft at its opposite ends.

In testimony whereof, I aflix my signature, in presence of two witnesses. 7
