2 Claims.
This invention relates to a device for shutting off sprinkler nozzles and the principal object of the invention is to provide devices which may be used with 4any sprinkler head of whatever size,
type or manufacture for` the purpose of shutting the same off after the fire, which occasioned the opening of the sprinkler, has been put out.
A further object of the invention resides in the provision of a device of the class described comprising an implement having a pair of elongated jaws pivoted together at one end, one of said jaws at the opposite end being provided with a guide for cooperation with apart of the sprinkler head for guiding the tool into operative position therewith and the other jaw having at its opposite end an element, such as a rubber hemisphere or the like, for engagement with the opening of the nozzle head to close the same, said jawsV being held together by spring means and separated by screw means or the` like.
VOther objects and advantages of the invention Will appear hereinafter.
Reference is to be had to Vthe accompanying drawings in which f Fig. 1 is a view in elevation showingV the present device as it appears when in use shutting olf a sprinkler head; and
Fig. 2 is a view in front elevation looking in the v direction of arrow 2 in Fig. 1 of the device alone.
As shown in the drawing, the reference numeral IG indicates a sprinkler head which may be of any size, type or manufacture. Every sprin- 2 ment 26. rlhe socket 30 is provided with a groove receiving a forked type of holder 36, allowing the socket to turn therein; the holder 35, in turn being connected to the jaw I8 by means of a chain 38. A rod or pole 40 maybe screw threaded into1 the bottom end of the socket at 42, so that the rod may be released from the socket so as to leave the socket in position, or if desired, the socket itself may be removed by proper manipulation of the connection 34. The holder 36 connects the socket with the arm I8 because in most cases it is desired that the socket 3@ shall be a part of the device and even though not connected therekler head comprises a ring part I2 adapted to e be screwed into a Water pipe and a yoke rising therefrom and terminating in a part I4. These sprinkler heads are old and well known and need no further description.
The tool herein described for shutting off the sprinkler head comprises a jaw I6 and a jaw I3 at its opposite end with a deformable hemisphere or the like 22, which is used to close the opening in the connection VI2 so as to Shut olf the sprinkler head. The jaw I8 has a screw threaded aperture "at 24 in mesh with a screw 26 extending therethrough and impinging on the underside of the upper jaw I6 at 28 to force the jaw I6 away from the jaw I8, it being understood that the upper jaw Iis locked against the element I4 of the sprinkler head, thus forcing the soft element The jaw I8 is providedV 22 downwardly into Yposition to shut off the opening in the connection I 2.
In order to turn the screw 26, there is provided a socket 30 having a bayonet-type slot 32 receiving a projection 34 on ,the -screw threaded eleto, as shown in the drawing, still it is more convenient to have a socket 3D for each sprinkler shut-off device.
The jaws are held together by means of a screw 44 having a head 4B and a spring 48 so that whenever the screw 26 is backed olf, the jaws will come together.
Ahead, with the extra advantage that the device here is capable of closing olf any and all sprinkler heads of whatever manufacture.
A spring 50 may be placed on the screw 26 to hold the tool in oriented relation to the rod all), so that the tool may be directed and will not swing around on the threads.
YHaving thus described my invention and the advantages thereof, I do Vnot wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but what I claim is:
1. Universal sprinkler shut-off device comprising a pair of interpivoted arms, a rounded valve element on one arm remote from the pivot axis, said element facing away fromV the other arm, means on the latter to engage a part of a sprinkler head so that the element will close the sprinkler upon the separation of said arms when the said sprinkler part is engaged .by said means, a screw threaded into and throughV one arm and bearing on the other arm to separate the arms upon rotationof the screw in the appropriate direction and to allow the arms to be moved toward each other upon rotation in the opposite 4 REFERENCES CITED The following references are of record in the le of this patent:
