AUTOMATIC FIRE-EXTINGUISHER.
- SPECIFICATION forming part of Letters Patent No. 538,593, dated April 30, 1895.
Application filed March 9, 1894. Serial No. 503,036. (No model.)
To all whom it may concern:
Be it known that I, JAMES NAYLOR, Jr., a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Automatic Fire-Extinguishers, of which the following, taken in connection with the accompanying drawings, is a specification.
My invention relates to what are commonly called sprinklers as used in connection with a permanent system for the automatic extinguishing of fires in buildings The object of these improvements is to produce anew article that will hold the pressure of the water with more certainty when the water is not required, and more sure to let it go in event of a fire so as to extinguish it.
It also has for its object the production of a sprinkler that may be made at low cost and by such means that will insure a uniform and exact standard to be easily maintained in their manufacture, so that .all the several parts are duplicates of each other and interchangeable.
It consists of the construction and operation of its parts in such a manner that the followin g features are attained: first, increased area of the fusible surfaces; second, increased area of exposed surface of the parts having the fusible surfaces; third, the conduction of heat from parts having the fusible surfaces reduced to the minimum; fourth, no fusible surfaces on the parts which directly support the valve; fifth, the instant parting at every point of the whole area of the fusible surfaces; sixth, the same strain may be given to the fusible surfaces notwithstanding the difference in the pressure of the water in the system; seventh, the impossibility of the drip from condensation or otherwise to reach the parts having the fusible surfaces; eighth, combined means of water distribution; and ninth, that each part may be separately finished and with little skill assembled or put together without any fitting whatever, all of which will be herein fully specified and setforth in the claims.
In the drawings, Figure 1 is a general elevation; Fig. 2, a side View, and Fig. 3 a top plan View, Figs. 4, 5, and 6 being detail views of parts shown also in the other figures.
A is the sprinkler head, which is screw threaded at a, for insertion to the fittings of the system; suitable provision being made so that a wrench may be applied in making the joint water tight.
B is an ajutage nozzle which being bored smooth and of proper'dimensions gives added velocity or force to the water at the orifice and therefore in capacity equal to the part supplying it.
C is the valve, having a flange c which serves the double purpose of holding the valve correctly to its seat and for retaining an aluminum insertion c, thus forming a composite valve ofmetals suitable for their respective purposes, viz:a soft non-corrosive metal to make the water joint and a strong metal to support it to its seat 0". The valve is also provided with a countersink c' vert side.
The head A is provided at D with internal screw threads for the insertion of the set screw E, said screw having an extension 6 of lesser diameter so as to form a shoulder c. This extension is provided with a countersink e and serves the double purpose of a support both for the valve and the water distributor F, which is freely mounted upon the said extension and in contact with the said shoulder so as to be easily revolved and is held to the screw E by the turning over of the upper edge thereof. This distributor is to be seen in the several figures, its function being so important that an exact description becomes necessary to render its action clear and uninto its obder-stood. Fig. 4 shows a face or plan view;
Fig. 5, a cross-section on line a; w of Fig. 4. The central part is conical, the sides of the cone being concave up to the edges of the rectangular openings ffff which at the points f'ff'f come to a feather edge with the under surface. The rectangular openings have all their edges at an inclination of about fortyfive'degrees to a radial line. Around the periphery is the sharp-edged flange f being square on the outside to the under surface, and inside flaring at an angle of about fortyfive degrees to the square edge and the under surface. Inside this flange and adjoining itare the series of projections f jections have tapering sides and are set at an angle of about forty-five degrees to a radial re se line. The under side of Fig. 4 is fiat and all the aforedescribed parts and projections are upon the same side and in one solid piece or casting.
The distributeris prevented from falling off the extension 6 by slightly turning over or riveting the upper edge of the said extension.
That part of the head A which is near to the distributer is serrated as shown in Fig. 1, making a series of sharp projections Ct, which serve in combination with the distrihuter F to give an improved distribution.
G G are toggles each being a duplicate of the other. They are pointed at one end for insertion into the countersinks c and e and at the other end are surfaces for proper bearing contact with each other and the semicircular recesses g g. The set of these toggles in their proper position is what is commonly termed a toggle joint as seen in Fig. 1, being held and sustained in such position by the stay H to the head A. This stay is composed of four pieces, viz., the two screws h 7L and the two disks h it. Each screw enters the hub of each disk and the flat face of each disk is united together by the fusible solder which melts at about 160 Fahrenheit. The stay may therefore be considered as integral, although in first setting, the screws h it give ample range of adjustment so that the toggles may be set more or less obtuse. One of the screws his interlocked by the semi-circular recesses of the toggles and the other passes freely through the opening h in the head A, and thus a tensile strain is given to the stay H while a compressive strain is given the toggles G G.
The advantages derived by this construction are in the main stronger means to hold the valve tight, and surer action, the operation being as follows:Being in place and a part of a permanent system which with the contained water is at or about Fahrenheit and a fire occurring near it, the sudden rise of temperature quickly imparts heat to the disks owing to their large exposed area, which heat is all retained because it cannot be conducted off through the light screws to other colder parts. As a consequence the solder melts at 155 Fahrenheit and allows the disks to part instantly at every point, even before the other parts have become heated at 120 Fahrenheit. The toggles, valve and half the stay H are forced away by the oncoming stream of water, and here it may be observed that the flange and projections of the distributer are so made that with the oncoming stream it is impossible for any of the released parts to become in any way entangled because of all the forty-five degree angles affordinga free release whenever contact of the parts occurs. The stream strikes the distributer directly on the cone, and by it, itis deflected without much loss of force outwardly coming in contact with the projections and flange part is thrown upward and part downward, passing through the rectangular openings and against the S61.
rated surface of the head from whence it is deflected in every direction. The force of the water striking the angular projection causes its rapid rotation, and by all these causes the general elfectis to break the stream into numberless drops and throw same in all directions, both upward and downward, and to have the same effect if placed either as a pendant as shown in the drawings, or reversed as it would be by being placed above the pipes of the system.
The half of the stay H which remains does not in any way hinder the stream, as it is securely held to the head, having freedom to pass farther back but not forward.
After the tire is extinguished the water supply is shut off at the main valve of the system and the several parts replaced without removal of the head A from the system.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In an automatic lire extinguisher the combination with the head Aprovided with a nozzle and the set screw E, valve 0 and toggles G pivotally supporting said valve to said nozzle from said set screw; of the stay H supporting said toggles to said head and provided with means for automatic release between said toggles aud. said head as herein shown and described.
