SPRINKLER-HEAD FOR FiRE-=EXTiNGUlSl-IERS.
SPECIFICATION forming part of Letters Patent No. 712,693, dated November 4, 1902. Arplicaticn filed January 3, 1902- Serial No. 88,345. (No model.)
To all 1071,0711. it may concern: will force the plates apart and allow the Be it known that I, ALLEN D. LINN, a citivalve-stem to rise until its upper end rests zen of the United States, residing at Grand against the end of the bolt F and the valve Rapids, in the county of: Kent and State of assumes the position indicated by the dotted 5 Michigan, have invented certain new and lines 0, giving the water a free fiow through useful Improvements in Sprinkler-Heads for the head out of the ports I) and against the Fire-Extinguishers, of which the following is sprayer H. If. it is desired to stop the flow a specification. of water from any particular head without My invention relates to improvements in shutting oil? the entire system, the yoke may [0 sprinkler-heads for lire-extinguishers for use be thrown over to the position indicated by with automatic tire extinguisher systems; the dotted lines in Fig. l, which will allow 69 and its objects are, first, to provide a waterthe valve to rise to the position indicated by head with which after it has been opened and the dotted lines at C and become seated upon while water is flowing through the valve may the valve-seat a, thus shutting off the flow :5 be seated and stop the flow of water, and, of water at once.
second, to provide for sounding an alarm The lowerend of the platesEis preferably when the valve has been opened for he outformed to a point, so that it may enter a flow of water. I attain these objects by the slight depression in the end of the valvemechanism illustrated in the accompanying stem, so that the bolt F may be readily turned 20 drawings, in whichand screwed down to hold the valve firmly Figure l is a vertical section of the head upon the seat a when in its normal state. 70 upon the line 00 as of Fig. 2.

the head and is provided with a port I) for .but the switch arm or lever I acts a double the discharge of water when the valve (J is purpose-namely, first, it tends to crowd the raised from the valve-seat a and also with a lower end of the plates E off of the top of the valve-seat a, designed to receive the valve valve-stem as said stem rises by reason of the 5 0 when the yoke G is thrown to one side to severance of said plates, and, second, to close allow the valve-stem D to pass the end of the the circuit from the battery J through the bolt F, as hereinafter more fully described. alarm appliance K in the usual manner of G represents the yoke that supports the nut closing electric circuits, and for this purpose G, through which the bolt F is screwed. This I prefer that it be pivoted to one arm of. the

reception of the fusible plates E, which are The yoke G is pivoted to the cylinder A, as thin plates of copper or other active heatat gg, in such amanner that it maybe thrown conductor that are soldered together to the over to one side, as indicated in Fig. l, to point of angle, as indicated in Fig. 3, and carry the end of the bolt F out of the line of 45 the angling ends are soldered to the wedging travel of the valve-stem D, so that the valve end of the clamping-bolt F, as indicated in may rise to and seat upon the valve-seat a, Figs. 1 and 2, in such a manner that the moas hereinbefore indicated. ment the solder is exposed to sufficient heat To render the valve positive in its action to melt the pressure of water under the valve upon either seat, I place a proper packing a upon each side, so that a water-tight joint may be assured upon either valve-seat. With this construction if, as often happens, the head is opened so that water flows through the ports I) and it is necessary to shut off the flow suddenly to avert damage to property all that is necessary is to strike the yoke Ga sharp blow with a stick or otherwise and throw it over, so that the valve-stem is free to pass upward, and the upper valve-seat is instantly covered by the valve and the flow of water stopped and held until the main supply can be shut off, if desired.
It is often necessary to fuse the plates E for the purpose ofinspection, and to avert the danger of the valve remaining unseated long enough to allow the air all to escape from the pipes and the water to flow out sufficiently to render inconvenience or damage I pivot a lever E to the plug B, as at e, in position so that the lever will rest between the plates E and the top of the valve-stem. \Vith this lever in this position as soon as the plates are unsoldered the lever will be carried up to contact with the end of the screw F, so that the unseating of the' valve from a will allow the pressure of air and water to escape, indicating whether or not the system is in order, and to avert the danger of flooding with water the lever E may be drawn to the position indicated in Fig. 1 and secured to place by the link 6. The offset 0 is placed in the lever'to avert the danger of throwing the yoke G over by the force of the lever E, as it is thrown up against the bolt by being arranged to receive the end of the bolt at one side and the end of the valve-stem at the other side. This is designed only for a lever that is permanently placed between the valve-stem and the end of the bolt. In case of a temporary lever to be used only after the head has been tested a straight lever having a proper hook for engaging the pivot e may be used.
f represents a cover of lead-foil or other suitable material to cover the water-ports d for the purpose of preventing dust, &c., from entering the chamberand interfering with the properseatingofthevalve. Thiscovershould be so applied and adjusted that it will not interfere with the full free flow of the water out of the ports when the head is in active operation.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
1. Inasprinkler-headfor fire-extinguishers, the main portion or cylinderA having a valveseat within, a plug at the upper end having a valve-seat at its lower end and a Water-port therethrough, in combination with a yoke pivoted to the cylinder, a bolt passing through said yoke and having the lower end tapered to a wedging form, and thin metal plates fusibly connected together and to the Wedging end of said bolt, substantially as and for. the purpose set forth.
2. In a sprinkler-head for fire-extinguishers, a cylinder having a valve-seat, a plug screwed into the end of said cylinder and provided with a valve-seat and awater-port, a doublefaced valve within said cylinder, a yoke pivoted to said cylinder and supporting a nut, a bolt through said nut, the lower end of which is tapered to a fiat wedge form, thin metal plates soldered together and to the wedged surfaces of said bolt, a valve-stem held to place by said bolt and plates, a lever pivoted to the yoke and in contact with the upper end of the valve-stem, and an electric switch and alarm system, substantially as and for the purpose set forth.
3. In asprinkler-head for fire-extinguishers, a main cylinder, a valve and valve-stem within said cylinder, and a plug screwed into the end thereof,iu combination with ayoke,a bolt screwed through said yoke the lower end of which is wedged, a thin sheet of metal soldered to each side of said wedge and soldered together below said wedge and extending to and bearing upon the upper end of the valvestem, substantially as and for the purpose set forth.
4. In asprinkler-head for fire-extinguishers, a main cylinder provided with valve-seats and water-ports, a valve and valve-stein, a plug having water-ports therethrough,a yoke, a retaining-bolt and fusible plates, and a lever pivoted to the plug and lying across the end of the valve-stem and beneath the end of the plates, substantially as and for the purpose set forth.
5. In asprinkler-head for fire-extinguishers, a plug, a retaining-yoke and fusible plates, in combination with a lever pivoted to the plug and supported beneath the fusible plates a valve-stem held to place by said lever, and a link for holding said lever to place, substantially as and for the purpose set forth.
