UNrTnp STATES JOHN O. MAOKEY, OF SYRAOUSE, NEWv YORK.
AUTOMATIC FIRE-EXTINGUISHER.
SPECIFICATION forming part of Letters Patent No.36`6,177,dc1ted July 5, 1887.
Application filed December 4, 1886. Serial No. $10,739. (No model.)
To @ZZ whom, it may concern:
Be it known that I JOHN C. MACKEY, a citizen of the United-States, residing at the city of Syracuse, inthe county of Onondaga, State of New York, haveinvented certain new and useful Improvements in Automatic Fire Extinguishers, of which the following is a full, clear, .and exact description, reference being had to the accompanying drawings, in which- Figure l representsa vertical sectional view of my improved lire-extinguisher with the valve closed. Fig. 2representsasimilar view showing the valve released. Fig. 3 represents a bottom plan View of the deflector with the locking-plate in position. Fig. 4 represents a tep plan view ofthe same, showingthe details of its construction. of the deilector, showing the supportingestuds. Fig. 6 is an isometric view of the valve disk. Fig. 7 is a similar view of the valve-stem.
lVIy :invention relates to automatic sprinklers or reextinguishers; and it consists in the construction and combination of devices hereinafter described and claimed.
To enable others to become skilled in the art to which my invention appertains, I will now describe the manner in which I have earried it out.
The device herein described and illustrated is for use in extinguishing a fire that may oe cur within a structure or room of a building, and is designed to be placed in the upper part of a room or structure, and adapted to a pipe or conduit for carrying water or chemiealsunder pressure into the chamber of said device.
In the said drawings, A A represent the body of the sprinkler, which is divided horizontally at or near the center, the upper portion, A, being threaded and capable of attachment to a pipe 0r conduit containing water or chemicals under pressure, a flange, l, serving as a nut,whereby the body A is screwed to the pipe or conduit. rlhe upper portion of the body is provided with aseat, 2, against which is' securely held a suitable valve, the construction and operation of which will be hereinafter described. The lower portion, A, of the body is provided with a discharge-aperture, C, and is perforated to receive the upper ends of screws or bolts D, which connect said body with a deiector, E. This dedector E has a Fig. 5 is a side elevation central" perforation, 3, which guides the movements of a suitable valve-stem,` and also has a series ofdouble inner projections, F F", the inner series, F, being arranged around the central perforation, 3, and directly beneath the discharge-aperture O in the body A, whilethe projections of the second series, F', are formed around the deilector near its outer circumference. f
From this description it is manifest when the valve is released from its seat the volume of water or chemical in its descent comes in contact with the inner series of projections, F, andtherehy divides the liquid, which is forced outward by the pressure in the pipe or conduit unt-il these divided streams come in contact with the outer series of projections, F', when the water is again divided, this time in iiner streams, which are 'forced upward by the deflector against the ceiling of the structure and descend upon the fire in `fine sprays. The ar rangement of the double series of deiiectors enables the water to be discharged not only in finer streams, but also to cover an area much larger than if a single row of projections or a iiat disk were employed to deflect the water or chemical. Y
Thevalve G in the present case consists, essentially, of a disk mounted .upon the upper end of a valvestem, H', and provided with a soft-metal face, K, adapted to come into contact with the rounded edges of the valve-seat, and thereby form an absolutely tight joint between the two. It will be observed the valve is located at the eXtreme upper end of the body A, and is designed to prevent the water or chemical from entering the body oi' the sprinkler until the temperature of the room or structure fuses the solder which retains the valve in position, and also prevents allliability of the liquid freezing and thereby arresting the successful movements of the device.
As before stated, the valve is attached to the upper end of the valvestem H, and has a shoulder, 4, upon its lower face, which is designed to come into contact with and find a seat upon suitablepins, 5, projecting upwardly from the inner face ot' the lower portion of the body, as shown in Fig. 2. The valve-stein projects downward into the aperture 3, and when the valve is closed the lower end of the stein,
is nearly flush with the lower face of the deilector. Upon the bottom of the defieetor I place two studs, M O, each of which is notched, as is shown inthe drawings.
Upon or astride of the stud M, I place the spring R, one end of which is slotted to tit over the stud, and by catching under the notch 6 it has a spring-bearing upon the stud.4
N isa plate of metal provided with slots 7 8, of proper size to iit loosely over the studs, and when placed in position one slot, 7 ,catches under the notch 9 lof stud M and the central portion bears against the spring R, compressing it against the bottom of the valvestem, holding the valve closed, and thc other end of this plate is passed over and partly upon the stud O, Where it is soldered fast by a drop of solder, which is fusible.
It will be thus observed that in the event of fire rbreaking out in a room or structure in which the device is located the solderuniting the plate N with the deflector-stud O melts and permits said plate to be thrown off by the spring R, it and the spring falling, and said stem dropping to its seat upon the pins 5. The water or chemical being thereby released is discharged upon the fire and extinguishes it.
Having described my invention, what I claim, and desire to secure by Letters Patent,
l. The combination, with a body-having an annular valveseat at its extreme upper end, of a valve-stem, a valve secured to said stem and provided with a soft-nnetal face which engages the seat, a deiector having fianges,bot tom studs, M O, a spring, R, and a plate iitting over one stud and adapted to be soldered to the other stud, substantially as shown and described.
2. In an automatic fire-extinguisher, a valve support consisting of a spring connected to a stud projecting from the detlector and bearing against the bottoni of the valve-stein and a cross-bar compressing-said spring and fusibly connected to studs projecting from the dcector, substantially as described.
3. In an automatic fireextinguisher, a delector suspended from the body and provided with bottom studs, in combination with ,a valve-stem, a spring connected to one stud, and a cross-bar bearing against the free end of the spring and fusibly connected to the studs, substantially as shown and described.
In witness whereof` I have hereunto set my hand this 16th day of November, 1886.
JOHN c. MAOKEY.
