SPRINKLER HEAD FOR AUTOMATIC SPRINKLER SYSTEMS I .Filed 051. 25, 1935 Patented Apr. 6, 1937 UNITED STATES QFFICE' SPRINKLER HEAD FOR AUTOMATIC SPRINKLER SYSTEMS Arthur C. Rowley, Drexel Hill, Pa., assignor to Globe Automatic Sprinkler Company, Phila- 3 Claims.
This invention relates to improvements in sprinkler heads for automatic sprinkler systems, and the principal object of the invention is to provide a sprinkler head frame of novel and improved construction which can be manufactured at materially lower cost and will be generally more efficient than the frames made in accordance with the prior practices.
Frames of this character commonly comprise spaced arms which at one end are attached to the body of the sprinkler head and which in effect form a supporting yoke for a deflector element located in the path of the stream of water projected from the said body, the function of this de- 7 flectorbeing to disperse and spread the water over a relatively large area. Such frames heretofore have been in the form of castings, with the deflector element being formed as a separate part. These prior frames not only had the disadvantage of relatively high cost of manufacture but were relatively inefficient, in that the cast support frequently interfered with the efficient operation of the deflector.
The primary objects of the present invention,
therefore, are to reduce the cost of manufacture of frames of this character, and at the same time to provide a frame which is generally more efficient in the respects hereinafter set forth than the frames of the prior art.
In the attached drawing:
Figure 1 is an elevational view of a frame made in accordance with my invention showing the manner of its attachment to the body of the sprinkler head;
Fig. 2 is an enlarged front elevation of the completed frame;
Fig. 3 is a side elevational view of the frame;
Fig. 4 is a top plan view of the frame, and
Fig. 5 is a view of the sheet metal blank from which the frame is produced.
The frame made in accordance with my in vention is produced as an integral structure from sheet metal, the initial step consisting in forming a flat blank from the metal sheet by a simple stamping operation. This blank comprises a mid section I of roughly circular form, the peripheral portion of which consists of an annular series of radially projecting tongues 2. Extending from the outer ends of adjoining pairs of the tongues,
designated by the reference characters 2a, 2a, at
diametrically opposite sides of the mid section 5 are arms 3, 3, said arms having outwardly diverging side edges 4, 4, and each terminating at their outer ends in rectangular terminal portions 5. As illustrated, the circular mid section is provided with apertures 6 arranged in spaced relation around the center.
The fiat blank described above is partially formed to the finished shape by means of a stamping operation, which involves the pressing of the central portion of the mid section I from the normal plane of the latter to produce a central conical projection l on one face of the mid section and a corresponding concavity on the other face, the apertures 6 lying on the inclined sides of this central conical projection. Also and as clearly illustrated, the tongues 2 and 2a are turned down or depressed toward that face of the mid section from which the cone 1 projects. In this operation also the arms 3, including the terminal portions 5, are bent to channel form, said channel decreasing in depth toward and terminating approximately at the outer ends of the tongues 2a from which, as previously described, the said arms extend.
In succeeding operations, the channeled arms 3 are bent into substantial parallelinity with each 7 other and substantially perpendicular to the normal plane of the mid section I, and the longitudinal edges of the channeled terminal portions 5 of the arms are brought together, thereby giving said terminal portions a roughly cylindrical form. The said terminal portions are then machined externally to true cylindrical shape suitable for insertion in cylindrical sockets or openings formed for their reception in the body of the sprinkler head, as shown in Fig. 1.
In assembling the frame with the body of the sprinkler head, the cylindrical end portions 8 of the arms are passed through the openings 90. in lugs 9 projecting from opposite sides of the body ll] of the sprinkler head. The portions 8 of the frame are sufiiciently greater in length than the thickness of the lugs 9 to permit the riveting or upsetting of the ends, as indicated at 8a in Fig. 1, to thereby rigidly and efliciently secure the frame to the body of the sprinkler head.
The frame is characterized by simplicity of form and manufacture and neatness of appearance. It is also highly -eflicient in the water-deflecting function, in that the deflector portion is substantially symmetrical throughout, and that surface of the deflector presented to the water stream is entirely unobstructed, this by reason of" the fact that as described the supporting arms merge into the outer ends of the depressed deflecting tongues 2a.
There may be some modification in detail without departure from the invention.
I claim:
1. A sheet-metal frame for sprinkler heads comprising a mid section of roughly circular form constituting a deflector, and integral supporting arms extending from opposite sides of said deflector, said arms having a substantially U-shaped cross section throughout the major portion of their lengths and having each a cylindrical terminal end portion for attachment to the body of the sprinkler head.
2. A sheet-metal frame for sprinkler heads comprising a mid section of roughly circular form having a pressed-out substantially conical center portion at the under side, the peripheral portion of said mid section consisting of a series of outwardly projecting tongues and said tongues being turned down to form with said conical center a concaved deflecting surface at the said under side mid section, said arms being shaped throughout the major portions of their lengths to longitudinal channel form, and each arm having a cylindrical extremity constituting means for attaching the frame to the body of the sprinkler head.
