FUSIBLE LINK FOR AUTOMATIC? SPIt-INKLEBS Specification of Letters Padint.
Patented May '14. 19 t '5 Application filed December 11, 1911. Serial No. 665,134.
To all w/rom it may concern Be it known that l. ARM (1. ltaxxmin. a citizen of the United States. residing at Chicago, in the county oi Cook and State of Illinois have invented certain new and. useful .lmprovements in Fusiblc Links for ziutomatie Sprinklers, of which the tollowing is a specification. I
This invention relates to devices used to hold the discl'iarge orifices ot a water delivery System in a closed position until a determined temperature prevails at or around one or more oi said oril'ices and when said determined temperature does prevail to automatically release the valve or cover of said oritice and permit the said valve or cover to be moved from its seat by the pressure of the water on Saidsystem, and water to be discharged therefrom.
The. objects of this invei'ition arcs-to obtain a device'whieh at climatic tem 'ierature, or at the temperature which is designed to prevail in artificially warmed buildin ;s will sustain the strain incident to its use a's a lock or latch, or as a connecting link between locking or latching levers, without. liability oi breakage and thereby permitting the valve or cover to pc removed from its seat; to obtain a device which will not be injuriously subject to corrosion or other injury to materially lessen its resistance to strain when the same is left in use for a considerable length of time, and to obtain a device which, when a determined temperature prevails upon (1' around it, will automatically give way and permit the valve or cover to be moved from its scat.
Further objects of the invention are to obtain a device of the el'iaratacr described which can be economically made, easily inspected and readily put into use by a person not specially skilled in the art.
In the drawing Figure l is a side elevation of a nozzle provided with a valve seat and valve thereon, with means including a device embodying this invention to hold the valve. seated. Fig. 3 is an elevation at an angle of 90 degrees from the view illustrated in Fig. 1, of a portion of the nozzle and valve seat illustrated. in said Fig. t. Fig. 3 an end View of one element of a device embodying my invention. Fig. 4- is an end view of an additional element of the device embodying the invention. Fig. 5 is a front elevation of a device embodying the invenl lion. and Fig. (3. is a sertirnial view on line (l -(3 ol. .l ig'. 5. viewed in the direction indicated by the arrows. l ig. T is a sectional view of a modification ot the device embodying the invention. V
Similar letters ret'er to 'similar parts throughout the several view A represents a screw threadml nozzle provided with a passage way then i hrough. said passage way being indicated by broken lines (1, Figs. 1 and 2.
it is a valve seat-at the discharge end of the passage way u. 7
Cl is a valve or cover on valvcseat B.
l) is a lillllllt. and it is a toggle joint coin prising levers c, a.
F a link (anbodying the invent ion lWltl-il mounted on levers (2 c, to hold said levels in position with the toggle joint l) pressing cover or valve (L lirmly on scat 1'3. lhe link F comprises the parts f, f, f", and solder j"" joining said parts together.
f" is a rib on part f. The parts f are-duplicates each of the said parts being provided with the groove f which fits to the rib f of part j". The solder f" (see Fig. (3) holds said parts f, f, 1'', together.
In the modification illustrateifl in Fig. 7, F represents the link and it is composed of the parts f, f, f, joined together by solder as is the device which is illustrated in Figs. 1, 5 and 6. The modification consists merely in a change in the shape of the rib on part f, the said rib being circular instead'of rectangular in cross section, and a corresponding change in the groove on part f,
\Vhatever the shape of the rib of the part 7' the groove or corrugations in parts f" are lit in said groove or corrugatimis.
y is an aperture in part f and y, g, are apertures in parts f".
To assemble the elements forming this invention a member f and duplicate members f are soldered together, the solder being interposed between the duplicate parts f" which are adjacent to each other and between the inner faces of the grooves f of said parts f and the faces oi. the rib f" of part f.
The edges of the several parts f, f, are soldered so that no crack: or (melting is left on said edges either belwveen the parts f or between the grooves f and rib f.
WVhen the several parts f, f f are of corresponding shape so that said rib will form a toggle joint, (E), and the joined together by solder f" and it is desired to put the device into use the levers e, e, are respectively mounted in frame D to ends of. said levers are inserted in apertures g, g of link F.
When the link F is in position on levers e, e, it holds the toggle joint E in place and the cover or valve 0 is held firmly to seat B closing the aperture in nozzle A.
If the temperature of the device is less than the determined temperature at which it is desired to have the cover or valve C released the link Will maintain the levers e, e, and the toggle joint E in place,'but when said device is raised to the determined temperature the solder f is melted, or at least itstenacity is weakened, and the parts f, are released from each other and from the rib fof part I elaim;--
A fusible link comprising three members joined together by solder, one of said members consisting of a metal body part provided with an aperture therethrough and having a horizontally extending rib on the lower edge thereof, and the remaining parts substantially duplicates and respectively consisting of a metal body part provided with an aperture therethrough and having a horizontally extending recess on the upper edge thereof, fitting to the corresponding side of the rib on the first named part.
Signed at Chicago, Ill, this 8th day of December, 1911.
