JOHN W. KLEINHAN, OF ALEXANDER, NORTH DAKOTA.

GOVERNOR FOR STEAM-ENGINES.

Specification of Letters Patent.

Patented Jan. 14, 1908.

Application filed February 27. 1907- Serial No. 359580- To all whom it may concern:

Be it known that 1, JOHN W. KLEINHAN, citizen of the United States, residing at Alexander, in the county of McKenzie and State of North Dakota, have invented certain new and useful Improvements in Governors for Steam-Engines, of which the following is a specification.

This invention has for its object to devise a governor designed most especially for traction engines since it is highly sensitive and responds quickly to changes of speed. It is to be understood in this connection that the governor is not restricted to any particular type or form of engine and may be readily adapted to engines operated by steam or other fluid medium such as compressed air.

The invention provides for automatic and manual adjustment of the induction valve, the construction being such as-to admit of the adjustments being effected whether the engine is in operation or at rest.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and ac companying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which:

Figure 1 is a sectional view of an induction valve and governor embodying the invention. Fig. 2 is a sectional view of the valve showing the parts on a larger scale. Fig. 3 is a sectional view of the valve on the line a;:z; of Fig. 2. Fig. 4 is a sectional view of the governor showing the parts on a larger scale. Fig. 5 is a detail perspective view of the valve seat. Fig. 6 is a detail perspective view of the valve.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The valve embodiesa casing 1 provided with an inlet and an outlet in the usualmanner. -Within the casing is located the valve 2 and the valve seat 3 each being of cylindrical form and having corresponding openings in their sides. The seat 3 is adjustable and fits end portions of the valve casing by a steam tight joint, packing 5 being fitted in grooves near the ends of the seat to insure a close joint being obtained between the seat and end portions of the casing. A rod 4 has adjustable connection with the valve 2 and connects the same with the governor mechanism so as to vary the position of the valve with reference to its seat to control the amount of steam or other motive medium admitted to the engine in a given time. The lower end of the valve seat 3 is provided with an extension in which is formed an oblong opening to receive an eccentric 6, the latter being fast upon the shaft 8 mounted in bearings provided in stuffing boXes 9 and 10 located at opposite sides of the casing 1. The shaft 8 is provided at one end with an operating handle 7 to admit of turning the eccentric 6 to effect adjustment of the valve seat with reference to the valve 2 so as to control the supply of steam or motive medium to the engine under normal conditions. Considering the valve 2 as occupying a given position movement of the lever 7 will through the eccentric 6 shift the valve seat 3 so as to vary the effective size of the openings between said seat and valve.

The governor comprises a frame 11 from which projects a spindle 13 through which the valve rod 4 loosely passes. A sleeve 12 is mounted concentric with the spindle 13 and is provided at its lower end with a bevel gear 21 which meshes with a companion bevel gear 21 fast to the inner end of a shaft 22 and which shaft is provided at its outer end with a pulley 23 to which rotary movement is imparted from any convenient operating [part of the engine. Governor arms 16 are pivoted to opposite sides of the casing 12 'and their lower ends are provided with ballweights 15 and their upper ends are connected by links 19 to a collar 17 which is rotatably mounted upon a sleeve 18, said collar 17 and sleeve 18 being housed by the sleeve 12. The sleeve 18 telescopes upon the spindle 13 but is held against rotation on said spindle and simply moves vertically. The collar 17 is rotatable upon the sleeve 18 and about an extension thereof, balls being interposed between the collar and sleeve to reduce the friction to a minimum amount. set nut 20 is threaded upon the upper portion of the valve rod 4 and enables adjustment of the same and the valve 2 as may be required.

Motion being imparted to the shaft 22 when the engine is in operation is transmitted from said shaft to the sleeve 12 through the bevel gearing and when the sleeve 12 exceeds the allowable speed, the governor balls 15 fly outward and cause the collar 17 and sleeve 18 to move downwardly and carry with them the rod 4 and valve 2 with the result that the area of the induction ports of the valve and valve seat is reduced thereby shutting off a portion of the steam or motive medium and forcibly reducing the speed of the engine. As the speed decreases the governor balls move inward and raise the parts 17 and 18 and the valve 2 thereby increasing the area of the induction ports and admitting a greater amount of motive medium to the engine.

Having thus described the invention, what is claimed as new is:

1. In a device of the character described, the combination of a casing, a valve seat adjustably mounted within the casing, a valve cooperating with the valve seat, a transverse shaft mounted upon the casing, and a cam carried by the shaft for adjusting the valve seat with reference to the valve.

2. In a device of the character described,

the combination of a casing, a cylindrical valve seat adjustably mounted within the casing and provided at its end portions with packing rings for producing a close connection with the casing, a valve mounted within and cooperating with the valve seat, a transverse shaft journaled in the casing, and a cam carried by the shaft and engaging the valve seat for adjusting the same.

3. In a device of the character described, the combination of a casing, a valve seat located within said casing, a valve slidable within the valve seat and cooperating therewith, a governor mechanism having an op erative connection with the valve, an extension projecting from the valve seat and provided with a laterally elongated opening, a shaft journaled in the casing and extending through the opening, and an eccentric mounted upon the shaft and engaging the opening to adjust the valve seat.

In testimony whereof I a'l'IiX my signature in presence of two witnesses.

JOHN I/V. KLEINHAN.
