AUTOMATIC VALVE.
Specification of Letters Patent.
Patented March 2, 1909.
Application filed May 14, 1907. Serial No. 373.606.
United States. and residents, respectively, of 1 Woodstock, in the county of il'ilftllll and State of New Hampshire, and of 'lhornton, in said county and State, have invented certain new and useful Improvements in Automatie Yalves, of which the following is the specification.
The invention relates to valves inserted in pipe lines, so constructed that when they become overheated they will open automatically and release steam or any liquid dcsirable.
Figure 1 of the accompanying drawings shows the valve, partly in sections, closed, and Fig. 2 shows the same valve open.
The same letters of reference are used to indicate corresponding parts in all views.
In the accompanying drawings. (i represents any valve of the type shown which -an be opened by pressure against the under side.
F represents the valve casing with packing gland removed. l
l) is the .valve stem made without threads or having the threads removed.
J shows the threads in the casing and H the threads for screwing on the packing gland. f
l3 shows a metal arm enlarged at H. drilled and tapped to lit. the thread on the case, and bent upward to form a fulcrum for the lever A which turns on the pin C, rests on the end of the valve-stem D and is held in place by the fusible link E connecting it with B. \Yhen the fusible link 1) becomes overheated it melts releasing the lever arm A, which in turn releases the valve (i causes it to rise,.opening the valve and allowing steam or other liquids to escape.
\Ve claim- 1. In an automatic valve the combination of a valve body, a valve which can be opened by internal pressure acting against the valve head, the valve body having an extension through which the valve stem passes, an L-shaped bracket screwed to said extension;
a lever arm pivoted to one end of said bracket and resting on the end of said stem and holding said valve head to its seat, and a fusible link securing said lever arm to the other end of said bracket, substantially as described and for the purpose set forth.
2. In an automatic valve, the combination of a valve body having a seat and an inlet and an outlet passage. an extension mounted on said body. said extension having a threaded extremity, an L-shaped bracket held directly on said extremity, an arm pivoted to one end of said bracket, fusible means adapted to bind said bracket and arm together, avalve head and a smooth stem carried thereby and passing through said extension, the valve head being adapted to be held 'on its seat by the said arm against the pressure of the fluid in the body, substantially as described and for the purpose set forth.
In testimony whereof we have afiixed our signatures in the presence of two Witnesses.
