' Applieation'filed; September 20,1918. Serial 11612545328.
To all ioh'om z't mayfconcemi Be it 'known that L'PHIIJP ALLEN, a citizen of "the "UnitedStates, residing at Providence, in the countyof Providence and State of Rhode Island, have'invented certain new and useful; I 'nprovements "1n 'Autolnatlc fSpriIiklers, of which'the'following is a specification.
(My invention relates to fire sprinklers automatically releasableby a'hi'gh tempera-- ture.
-The essential objects 'of my invention are facility in resetting the released parts; adaptability of repair by a millwright or other person, the link elsewhere than in engagementwith the sprinkler frame; to endure a maximum resistance to the hydraulic pressure on the valve; to assure a complete. discharge ofthe plates from the frame at a predetermined temperature; and to attain these ends an a simple, strong and inexpensive structure.
My invention consists essentially in employing torsional means for resisting the by draulic pressure upon the valve. Invention further consists in attaining the enumerated objects by such parts and such combinations of parts as fall within the scope of the appended claims.
In the accompanying drawings which form a part of this specification- Figure 1 is a side elevation of a sprinkler embodying my invention,
Fig. 2, a vertical central section of same showing the valve in side elevation, and partially broken away,
Figs. 3, 4, and 5, elevation, and a plan, locking members, and
Fig. 6, an enlarged section on line Fig. 3.
Like reference characters indicate like parts throughout the views. I
In the form of my invention herein shown it comprises a nozzle or pipe with external threads 9 and a square peripheral extension 11 at its discharge end upon which is the yoke the converging a side elevation, an end respectively of the or frame 12 comprismg arms 13. Fast to the end of the yoke is a diffusion plate 15. The yoke is preferably provided upon its under side with a notch 16. Resting upon the discharge end of the the valve at ""high temperatures.
and permitting resoldering of provided with a groove 27, V
nozzle is a circular' valve 17'of any usual construction, 3 preferably 'provided with a central notch "19.
It 215 "m conjunction with the described well-'known-parts 'of a-sprinkler head that "my invention-will -be detailed.
A str'ut or valve holding device retains the valve in its normally closed position atordinary'temperatures, and operates to release The holdingldevice includes brace plates 21- and' 22 of similar contour. These pl ates,-which areof steel, are fiat and-oblong and are'disposed edge'to edge at right angles to the axis of the nozzle. The' plat'es preferably have :respectively near-one end, tapering, laterally pro ecting, pointed portions 23 and' 24, -:adap'ted to seat-in the notches 16' and 19 respeotively. One plate 21 has its inner edge longitudinally "disposed shaped in cross section. The adjacent portion of the other plate 22 is throughout its length preferably beveled or tapered to form an edge 29, V shaped in cross section, which seats throughout its length in the groove 27. The combined width of the plates between the tips of the bearing portions 23 and 24 is greater than the distance between the seats 16 and 19.
A fusibly operative link is in this instance employed to clamp the outer ends of the plates for a purpose to be later detailed. This link comprises two oblong metal plates 31 and 32 fixed face to face with an intermediate layer 33 of solder or other metal of greater fusibility than the material of the plates. The other ends of the plates are provided respectively with laterally extending jaw portions 34 and 35. The latter comprise respectively arms 36 and 37, and inturned fingers 38 and 39, whereby are formed seats 40 and 41 respectively. The inner edge of each plate intermediate its length is provided with a swelled or curved por tion 43.
The described parts are assembled as follows: The plates 21 and 22 with the edge 29 seated in the groove 27 have their portions 23, 24, located in the seats 16 and 19. Because the breadth of the plates is in excess of the distance between the seats, the plates assume an angular relation to each other.
' Gopiesof this patent may be obtained f0 In order to exert and maintain a maximum reslstlng pressure upon the valve 17 the plates thus disposed are subjected to torsion, With pliers or any other suitable tool, the outer portions of the plates are forced into alinement with each other. While the plates are thus held the link is slipped over the alined outer ends of the plates. Thus the plates have their outer ends looked against assuming the angular relation still maintained by their opposite ends between the cessive hydraulic pressure. On the other hand this storedup energyinsures quick dissipation of the plates and link parts the in- "stant the solder in the latter is fused.
. It will be noted that by this construction the llIlk can have its parts soldered together at a point remote from the frame and be applied to the. plates at pleasure, which greatly lessens the usual labor of soldering V the strut mounted.
I claim 1. In an automatic fire extinguisher, the
combination with the valve and yoke, of
brace plates arranged edge to edge engaging 35 the valve and yoke, and means for maintaining the plates under torsional stress.
'2. In an automatic fire extingulsher, the
combination with the valve and yoke, of
brace plates in longitudinal engagement with each other disposed transversely of the yoke and torsional means upon the plates nearone end for forcing the opposite ends of the plates against the yoke and the valve.
3. In an automatic fire extinguisher, the or combination wlth thevalve and yoke, of two] brace plates provided with interengaging inner edges and disposed at lateral angles to each other intermediate the valve and V yoke, one'of the plates engaging the yoke and the other plate engaging the valve, and a link upon the ends of the plates for clamping the link-engaged portions of the plates 7 into a common plane.
In testimony whereof I have aflixedmy 55 signature. 7 V.
