JOHN EBERHARDT AND HERMAN EGHORST, OF CHICAGO, ILLINOIS.
STEAM-ENGINE GOVERNOR.
SPECIFICATION forming part of Letters Patent N 0. 764,661,
dated July 12,1904.
Application filed February 29, 1904. Serial No. 195,813. (No model.)
To all 1071,0771 it may concern:
Be it known that we, JOHN EBERHARDT and HERMAN lVEonoRsT, citizens of the United States, residing at Chicago, Illinois, have invented new and useful Improvements in Steam-Engine Governors, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof, and which Figure 1 shows our said new steam-engine governor in elevation. Fig. 2 shows said device in central longitudinal section. Fig. 3 shows a cross-section of the central stud k with the adjusting-nut Z in plan view, as seen from its under side.
Like reference-letters denote like parts.
The object of our invention is to produce a balanced steam-engine governor of that class wherein the stem of the governor is at the same time a part of the steam-pipe to the engine which shall be specially desirable for turbine and rotary steam-engines, but which may at the same time be used in all other kinds of steam-engines. To attain said desirable ends, we construct our said new governor substantially as follows, namely: The axial stem a has a shouldered thread g, which connects it to the engine, and a port or opposite ports 7) below which is a valve-seat (Z (Z, on which is seated the end of the pistonb when in its action it closes said steam-pipe. On the outer end of said stem are opposite arms in the ends of which are pivoted a pair of lovers it, weighted atp, whereof their outer ends are connected by links to the piston-rod holder 1', upon which there is an arch f, (shown broken away in part,) through which the threaded end of the piston-rod ciS secured and locked on top of the arch by a locknut, as shown. Said holder 2' is a disk which is chambered on its under side to receive the end of a coiled spring 7', through which and said holder is passed an axial stud Ki, which is threaded in the end of the stem a, and through said stud passes the piston-rod c, whereof its inner end is secured to the piston (Z. A hole Z in the piston passes steam into the chamber above it, and thereby balances the piston. The spring rests on an adjustable disk Z, which is threaded on the lower end of the stud Zc', which by raising and lowering increases and decreases the tension in the spring 7', and consequently the pressure on the disk or rod-holder v1, and thereby governs the action of the weights p on the piston (Z and either causes an earlier or a later closing of the ports by said piston. Said adjustmentis locked by a spring-bolt 12- in the stem a, actuated downward by its knob 0. The point of said bolt enters one of the holes m on the under side of said disk Z.
When the revolution of this governor is slow, the disk Zis let down low so that the tension on the spring 7' may be light because the centrifugal action on the weights 2 will be weak, and in proportion to a higher speed the disk or nut m is raised and the spring resistance increased, and through that the action of the piston (Z is governed. I
A pipe and easing c admit and hold steam which enters the tubular stem at through ports I).
What we claim is- 1. The combination of a combined rotary steam-pipe and governor-stem provided with steam-ports, of a-piston, weighted levers and intermediate parts to connect said piston and levers, and means to counteract the action of said levers.
2. The combination with a combined rotary steam-pipe and governor-stem provided with steam-ports, of a piston, weighted centrifugally-actuated levers and intermediate parts connected to said piston and levers and means to, regulatably, counteract the action of said levers.
3. The combination with a combined rotary steam-pipe and centrifugally-actuated governor-levers, of a steam-entrance to said pipe and means to close said steam-entrance connected to said levers.
t. The combination with a ported rotary stcm with arms carrying Weighted, centrifw said lovers, a nut to adjust the spring; rosistgully-actuated lei BPS, a piston actuated by ancc and a lock to said nut.
