BURTON P. HALL, OF FANWOOD, NEW JERSEY, AND WILLIAM GRIMSHAV, OF GLEN- ELLYN, ILLINOIS; SAID HALL ASSIGNOR T0 SAID GRIMSHAW.
FIRE-EXTINGUISHER.
Application filed November 11, 1918.
To all whom it may concern:
Be it known that we, BURTON P. HALL and WVILLIAM GRIMSHA\\', citizens of the United States, and residents, respectively. of Fanwood, in the county of Union and State of New Jersey, and of Glenellyn, in the county of Dupage and State of Illinois, have invented a new and useful Improvement in Fire-Extinguishers, of which the following is a specification.
This invention relates to fire extinguishers and relates particularly to improvements in automatic sprinklers and to an improved process of manufacturing the same, whereby they will be subjected to desired operating stresses.
The object of the invention, as it relates to the construction of the sprinkler, is to provide an automatic sprinkler of simple and relatively cheap construction and efiective for its designed purpose.
As it relates to an improved process of manufacturing our improved sprinkler, the object of the invention is to provide a new and novel process for subjecting the parts of the sprinkler to and maintaining them under desired operating stress, which shall be simple and effective.
To effect the foregoing objects, our improved sprinkler comprises the various features and details of construction and our improved process the various steps hereinafter described and claimed.
In the accompanying drawing, in which a sprinkler of our invention and constructed in accordance with our improved process is fully described,
Figure 1 is a side view of said sprinkler; and
Fig. 2 is a sectional view of the sprinkler frame on the line 22 of Fig. 1.
Referring now to the drawings, A designates the frame of the sprinkler as a whole, which, as regards its usual features, and, excepting as hereinafter particularly described, may be of any usual or approved construction and will be readily understood by persons familiar with the art without a detailed description thereof.
In accordance with our present invention, the water discharge nozzle of our improved sprinkler, instead of being formed directly in the neck 1 of the sprinkler, is formed by a bushing 2 fitted to the bore of the neck 1 so as to be initially movable endwise Specification of Letters Patent.
Patented Feb. 11, 1919.

therein, the seat for the cap 3, which closes the water discharge nozzle being formed at the inner end of said bushing 2.
As shown, the cap 3 is adapted to be secured in closed position by means of toggle levers comprising articulated strut members at and 5, the remote ends of which, respectively, engage recessed bearings 6 and 7 formed in the cap 3 and in the inner end of a boss 8 formed integral with the side arms of the sprinkler frame remote from the neck 1. thereof. Said toggle levers also comprise laterally projecting arms 9 and 10, the ends of which are connected by a fusible member designated, as a whole, 11, and which may be of any desired or approved construction. 1
e wish it understood, however, that the particular means shown for securing the cap 3 in closed position have no necessary relation to the present invention, and We do not, therefore, desire to limit ourselves thereto, as our invention contemplates the use of any desired or approved means for this purpose.
As shown, the bushing 2 is secured in the bore of the neck 1 of the sprinkler by an interlocking bead and groove 12 and 13 formed on the bushing 2 and in the bore of the neck 1 of the sprinkler, respectively.
In accordance with our invention, as it relates to a process of assembling the parts of the sprinkler and subjecting them to a. desired operating stress, the groove 13 is first formed in the bore of the'neck 1, after which the bushing 2 is inserted into the bore of the neck 1 of the sprinkler frame and the various parts of the sprinkler assembled, in the usual manner, the bushing 2 is then forced inward so as to subject the parts of the sprinkler to a desired operating stress. Said bushing is then expanded to form the bead 12 in position to interlock with the groove 13, and the sprinkler is then completed.
Any well known form of jack adapted for the purpose may be used to force the bush ing 2 endwise in the neck of the sprinkler frame, and any form of expanding tool adapted for the purpose-of which there are several known to the trade which may quickly and conveniently be adapted for the purpose-may be used for forming the bead 12, the plunger of the jack being made hollow to permit the expanding tool to be inserted into the bore of the bushing 2-.
We claim:
1. The process of stressing an automatic sprinkler of the'type in which the water nozzle is formed by a bushing secured in the neck of the sprinkler frame, which con sists in first assembling the parts of said sprinkler in operative relation with the bushing forming the nozzle of the sprinkler inserted in the neck of the sprinkler frame so as to be movable endwise therein, forcing said bushing endwise to subject the parts of the sprinkler to stress, and in then securing said bushing in position in the neck of the sprinkler corresponding to a desired stress on the parts of the sprinkler, substantially as described.
The process of stressing an automatic sprinkler of the type in which the water nozzle is formed by a bushing secured in the neck of the sprinkler frame, which consists in forming a groove in the neck of the sprinkler frame, assembling the parts of the sprinkler in operative relation with the bushing forming the nozzle of the sprin kler inserted in the neck of the sprinkler frame so as to be movable endwise therein, forcing saidbushing endwise to subject the parts of the sprinkler to stress, and eX- panding said bushing in line with the groove formed in the neck of the sprinkler when said bushing is in position corresponding to a desired stress on the parts of the sprin kler, thereby forming an interlocking bead and groove on said bushing and in the neck of the sprinkler, respectively, which will secure said bushing against endwise movement in the neck of the sprinkler and will fiepiea or this patent may be obtained for maintain the parts of the sprinkler under desired operating stress, substantially as described.
3. A sprinkler comprising a frame provided with a tubular neck and a bushing secured therein in position to subject the parts of the sprinkler to desired operating stress and provided With a bore which forms the water nozzle of the sprinkler,- substantially as described.
A sprinker comprising a frame provided with a tubular neck and a bushing secured therein in position to subject the parts of the sprinkler to desired operating stress and provided with a bore which forms the water nozzle of the sprinkler, the means for securing said bushing in the neck of the sprinkler comprising an interlocking bead and groove formed on said bushing and in the neck of the sprinkler, substantially as described.
5. A sprinkler comprising a frame provided with a, tubular neck, a bushing secured therein in position to subject the parts of the sprinkler to desired operating stress and provided with a bore which forms the water nozzle of the sprinkler, and an abutment for the nozzle closing means formed integral with the sprinkler frame, substantially as described.
In testimony, that we claim the foregoing as our invention, we our signatures this 7th day of November and 4th day of November, A. D. 1918.
