' P. W. GREEN 8!; A. E. TURNER;
GOVERNOR VALVE.
Patented Feb. 21,1882.
UNITED STATES PATENT OFFICE.
PAUL W. GREEN AND ALEXANDER E. TURNER, OF PHILADELPHIA, PA. 7
GOVERNOR-VALVE.
SPECIFICATION forming part of Letters Patent No. 254,004, dated February 21, 1882.
Application filed December 16, 1881.
' To all whom it may concern:
Be it known that we, PAUL W. GREEN and ALEXANDER/E. TURNER, citizens otthe United States, residing at Philadelphia, in the county of Philadelphia'and State of Pennsylvania, have invented certain new and useful Improvements in Governor-Valves,'of which the followingis a specification, reference being had therein to the accompanying drawings.
This invention has relation to improvements in steam-engine governor-valves, and particularly to a valve patented to O. A. Oond May 25, 1869; and the novelty consists in the peculiar construction of the cross-bar attached to the valve, as will be hereinafter more particularly set forth and claimed.
Figure 1 is a sectional view of the valve through its longitudinal center. Fig. 2 is a detail, partly in section, of the valve, crossbar, and valve-stem; and Fig. 3 is an end view of the same. I
In the accompanying drawings similar letters of reference indicate like parts of .the invention.
A is the globe or shell; B, the valve-seat or cylindrical chamber, in which the valve D works; and O is a steam-chamber. The valve D is hollow and open at both ends.
H is the cross-bar, semicircular in form, as shown in Fig. 2, the outer ends of which are secured to the valve D, and their inner ends approach each other, but do not touch, asufficient space being left for expansion when the valve is heated and in use.
E is the valve-rod, and is adjustable in the nut E held in recesses in the cross-bar H.
(No model.)
The valve D consists of a series of rings secured to the internal ribs, h, with spaces 1' between them for admitting steam from the chamher 0. j represents ports or spaces through the cylindrical valve-seat, which correspond in position and number with the spaces in the valve.
The steam is admitted to the chamber 0 through the opening F, and passes to the engine through the valve and opening G.
In the patent of Oond the cross-bar is a straight piece, and when heated expands longitudinally and causes the valve to stick in the cylindrical valve-chamber. In our improvement the division in the center of the crossbar allows it to expand toward the center, and consequently it is impossible for it to expand the valve so as to cause it to stick.
We do not claim the combination or arrangement of the valve-seat B, or the valve D, or the steam-chamber O with the ports t j, as these are fully shown and claimed in the patent to Gond above mentioned; but
What we do claim is-- In a governor stop-valve, the valve D, provided with the divided cross-bar H, as set forth.
In testimony whereof we affix our signatures in presence of two witnesses.
