AUTOMATIC VALVE.
Specication of Letters Patent.
Patented March 12, 1907.
Application led April 12,1906. Serial No. 311,335.
To @ZZ whom t may concer/2,:
Be it known that i, FREDERICK RICHARD J AcoBsnN, a citizen of the United States, residing at lortland, in the county of Multnomah and State of Oregon, have invented certain new and useful improvements in Automatic Valves 5 and 1 do 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 improvements in automatic valves.
The object ofthe invention is to provide a valve of this character which is adapted to be manually operated when desired and to be automatically closed when occasion requires.
A further object is to provide a valve of this character' which will be simple in construction, efficient and reliable in operation, and well adapted to the purpose for which it is designed.
l/Vith the above and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.
In the accompanying drawings, Figure l is a vertical longitudinal sectional view of the valve, showingl the same open. Fig. 2 is a similar view showing the position of the parts when the valve has been manually closed. Fig. 3 is a similar view showing the position of the parts when the same have been automatically closed, and Fig. 4 is an enlarged detail vertical sectional view of the outer end of the main valve-stem, showing the construction of the same and' the outer end of the valve-releasing rod.
Referring more 'particularly to the drawings, l denotes the valve-casing, which may be of the usual or any suitable construction, having a seat 2. Adapted to be engaged with the seat 2 is a valve 3, to which. is connected a releasing-rod 4. The releasing-rod 4 projects outwardly through a tubular valvestem 5, which is provided on its inner end with a coarse thread 6, adapted to engage similar threads 7 on the inner side of the valve-casing in the usual manner, whereby upon turning the stem 5 in one direction or the other the valve 3 is engaged and disengaged with the seat 2, thereby opening and closing the valve.
The outer end of the valve-rod 4 is pror vided with a iiari'ng head S, which is adapted l to be seated in a tapered recess 9, formed in l the outer end of the stem 5 and communil eating with the passage therein, through which the rod 4 extends. The rod 4 is normally connected to the stem 5 by the head 8, which is drawn or seated in the recess 9, and is secured therein by means of soft solder 10. While the rod and stem ofthe valve are thus connected, the stem may be turned by the usual hand-wheel 12 to manually open and close the valve, as hereinbefore described. Should a fire occur while the valve is in an open position, the solder 10 in the end of the valve-stem will be melted, thus releasing the head S and the rod 4 and permitting the pressure of the iiuid passing through the valve-casing to automatically close the valve upon its seat, thus cutting oli` the flow ofthe 'fluid after the manner of a check-valve.
A valve of this character is especially adapted for use in connection with gas-pipes or pipes containing any explosive fluids which might be released in a burning building by the melting or parting of the pipes.
From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.
Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined by the appended claims.
Having thus described my invention, what 1 claim as new, and desire to secure by Letters Patent, is-
l. A valve comprising a casing, a seat formed therein, a valve to engage said seat, a tubular valve-stein, a releasing-rod connected to said valve, and extending through said valve-stem, a fusible connection between said rod and said valve-stem, and a handwheel on the outer end of said stem whereby said valve-stem may be manually operated to open or close said valve, substantially as described.
2. A valve comprising a casing, a seat formed in said casing, a valve to engage said seat, a tubular valve-stem having at its outer end a tapering recess, a releasing-rod con-l nected to said valve and extending through said tubular stem, a flaring head formed on IOC gg y 847,182
the outer end of said rod to engage the recess my hand in presence of two subscribing wit in the outer end of said stem, a fusible plug to nesses. secure seid head in said recess, and means whereby said Valve-stem is manually oper- 5 ated to open and close said Valve, substan- Witnesses:
tally as described. I ROBERT Gr. MORROW,
In testimony whereof I have hereunto set BENJAMIN B. BEEKMAN.
