CHARLES IV. MCDANIEL, OF PORTSMOUTH, FEWr HAMPSHIRE, ASSIGNOR OF ONE-HALF TO PETER J. LYNCH, OF MELROSE, MASSACHUSETTS.
SPECIFICATION forming part of Letters Patent No. 768,676, datediAugust 30, 1904.
Application filed June 23, 1903. Serial No. 162,790. (No model.)
To all 1071.077?, it party concern:
Beit known that I, CHARLES IV. MCDANIEL, of Portsmouth, in the county of Rockingham and State of New Hampshire, have invented certain new and useful Improvements in Automatic Fire-Extinguishers, of which the following is a specification.
My invention relates to new and useful improvements in automatic fire-extinguishers; and its main object is to produce a new and eficient device which will not allow the discharge of water until the temperature has `reached a point caused by the presence of iire. This and other objects are carried out by the device hereinafter shown and described.
My invention consists of certain novel features hereinafter described, and particularly pointed out in the claims.
In the accompanying' drawings, which illustrate a construction embodying my invention, Figure l is a side view of my improved fireextinguisher, illustrating' the discharge of water when the device has become operative due to the presence of fire. Fig'. 2 is an end view of the fire-extinguisher with the parts in their closed position. Fig. 3 is a side view illustrating the position of the parts when the device is not in operation. Fig. 4 is a sectional view of the parts, showing the same in closed position. Fig. is a top plan view of the device detached from the water connection. Fig. 6 is a top plan View of the revolving distributer. Fig. 7 is a detail view of parts of the strut forming a lock controlling the flow of water. Fig. 8 is a plan view of a piece of mica and oiled paper hereinafter described. Fig. 9 is a detail'view of the valve with its spring.
Like letters of reference refer to like throughout the several views.
To the water-pipe A, passed along the ceiling, is attached the T B, into which is screwthreaded my improved lire-extinguisher C,- from which downwardly extend on opposite sides the arms D, carrying' the sleeve E, into which is screw-threaded the set-screw F, Fig. 4, provided with an inner channel FQ extending through from end to end. Closing the water-passage B in the extinguisher C is parts the valve H, and between said valve and its seat is placed a mica cap H', over which 1s 'placeda cap of oiled paper H2, which prevents corrosion around the valve-seat. This is liable to happenin suliite-mills and the like where alkali gathers around the valve,
Vcorroding the parts and preventing the open- C@ of brass,.which are soldered together, asindicated at C2, and provided with extension C, fitting into the bottom of the valve and into the top vof the set-screw F, which acts as an abutment, as shown in Fig. 4. Between these two parts, which are known in the art as a strut, is a pin C4, which prevents'sliding or sheering of the two parts C'. Over this strut at the front end there is a clamp C3, held onto said strut by solder C5.
` In tire-extinguishers at present on the market'the solder is depended upon to hold the strut together; but by my construction I do not rely upon the solder C2 alone, but use the clamp C3 to hold the strut together. Consequently the strut cannot separate and allow the water to iiow out when there is no lire. In the present devices the two parts of the strut are apt to separate, due to time and nonuse, and it has happened that the temperature has run up to 1000er so, which, with the force of the water, will produce a'strain on the strut,
causing a creeping or breaking away of said i strut. This liability is removed by the addition of the clamp C3, soldered onto the strut. WV ith the device set, say, at 16()O or at any other predetermined vtemperature the strut will not separate until that temperature is reach ed,and when such temperature is reached the clamp will fall off, due to the melting of the solder, and the two parts will separate and the valve H will open and allow the wat'er to iow from the main water-pipe A.
On the bottom of the set-screw F isa revolving distributer provided with slots (l and upwardly-turned vertical flanges G Gr and with outlets Gr", as shown in Fig. 6. Then the valve H is opened, as previously described, the water iiowing through the passage B/ strikes the distributer causing the same to revolve and the water passes downwardly through the openings G' and laterally from the openings G1 downward to the iire. There is also provided a central flow of water through the passage F, which water passes down directly into the vicinity of the fire. The passage I?l and the openings (ur provide a direct downward flow of water, and the movement of the distributer (if with its flanges causes an upward and lateral discharge of the water, as indicated in Fig. l.
The spring H3, located in a suitable recess in the upper part of the extinguisher C, bears at its lower end against the valve H and assists in opening the valve when the strut is separated.
This extinguisher can be set for any temperature desired, which is regulated by different solder, the higher temperature requiring harder solder than a lower temperature.
Having thus described the nature of my invention and set forth aconstruction embodying the same,what I claim as new,and desire to secure by Letters Patent of the United States, is-
l. In an automatic tire-extinguisher, a watersupply pipe having' a discharge-opening, a
valve-seat formed in said discharge-opening, a valve registering' with said valve-seat, a sleeve opposite to said 'valve-seat, means for supporting said sleeve. a screw turned into said sleeve and provided with a longitudinal channel in line with said diseharg'e-opening, a strut composed of two members having' oppo' site extensions on their inner ends respectively bearing against said valve and said screw, and fusible solder securing together the two members of said strut.
2. In an automatic lire-extinguisher, a Water-supply pipe having adischarge-opening, a valve-seat formed in said discharge-opening, a valve registering with said valve-seat, a sleeve opposite to said valve-seat, means for supporting said sleeve, a screw turned into said sleeve and provided with a longitudinal channel in line with said discharge-opening, a strut composed of two members having opposite extensions at their inner ends respectively bearing against said valve and said screw, fusible solder securing together the two members of said strut, a pin seated in opposite recesses in the adjacent faces of the members of said strut, and a clamp soldered over the outer ends of the members'of said strut.
3. vIn an automatic fire-extinguisher, a water-suppl y pipe having a discharge-opening, a valve-seat formed in said discharge-opening, a valve registering with said valve-seat, a sleeve opposite to said valve-seat, means for supporting said sleeve, a screw turned into said sleeve and provided with a longitudine channel in line with said discharge-opening, a strut composed of two members having opposite extensions at their inner ends respectively bearing against said valve and said screw, fusible solder securing together the two members of said strut, a pin seated in opposite recesses in the adjacent faces of the members of said strut, a clamp soldered over the outer ends of the members of said strut, a distrib uter rotatable on said screw and having slots passing through. the same, and upwardlyturned [ianges provided with openings projecting from said distributer.
In testimony whereof I have signed my naine to this speciiication, in the presence of two subscribing witnesses, this 5th day of June, A. D. 1903.
