UNITED STATES KARL REZNICEK, OF NEW YORK, N'. Y.
ROTARY NOZZLE.
Specification of Letters Patent.
Patented Feb. 8, 1921.
.Applicationv filed May 28, 1920. Serial No. 384,988.
T o all 'whom it may cof/wem Be it known that I, KARL REZNICEK, a citizen of the United States, and a resident of New York city, in the county of Kings and State of New York, have invented certain new and useful Improvements in Rotary Nozzles, of which the following is a speciication.
This invention relates to rotatable distributing nozzles or distributer hea'ds. Its objects are to provide a nozzle of its type in which the valve for the water vsupply pipe is free from all liability to become stuck fast in consequence of corrosion and to reduce the number of and to simplify the working parts.Y The type of rotary nozzle in which my invention is an improvement is shown in the Schmidt Patent No. 885,869 of April 28, 1908, and in the older and welllknown rotary globular head with projecting outlets which have been marketed for many years past under the name of Bresnans distributing or cellar nozzle, ,and extensively used by fire departments. It is shown on page 74 of the trade catalogue of the Toodhouse Manufacturing Compani of New York city, edition of July 1, 1918.
In the accompanying drawings forming a part hereof, and illustrating my inven-' tion:
Figure 1 is an under plan view.
Fig. 2 is a vertical central section at line 2-2 of Fig. 1. Q
Fig. 3 is a transverse section of line 3 3 of Fig. 2 of my improved rotary distributing nozzle.
Fig. 4 is an elevational view of the distributer nozzle looking at a side of the locking wing carrying bracket.
In that form of the invention now set forth, the chambered, rotary, distributing nozzle 1 with its horizontal outlets 2spaced about 90 degrees apart around its horizontal diametric portion is formed at its upper' end with a round depression to form the flange 3 and interior horizontal rib 4 around the center bore 5 which opens upwardly into the space within the flange 3 and which opens downwardly into the lower chamber 6 of the globular nozzle or head; the wall of this chamber being shown formed with water escape holes 7, below the series of outlets 2. The interior upper margin of the flange 3 is threaded for reception of a ball retaining ring 9 through the bore of which the under end of a water supply pipe screws into the upper interiorly threaded portion of the flange and has its under side opposed to the balls mounted on the flange 11. Thus the head or nozzle is made rotary on the coupling, the upper end of which is shown threaded at 12 for connection with a conduit forming part of a water supply system. f
The under side `of the coupling 10 is formed with a downwardly projecting annular shoulder 14 the under surface of which is horizontal and forms a valve seat, against which a valve packing 15 of yielding material and contained in the cupped valve head 16 of the upstanding valve for the under end of the coupling 10 is held in contact for tightly closing the coupling and preventing access of water to the chamber of the head. The valve head 16 is of less diameter than the interior diameter of the center bore 5 bounded by the interiorly projecting horizontal rib 4 and is inclosed by the interior wall 17 of the rib which is wholly out 4of contact with the valve head by av considerable clearance 19 that is wide enough to prevent the rib wall and the valve head from becoming stuck together by corrosion of the opposed metal. The rib 4 is formed with openings 18 each putting the chamber of the head into communication with an outlet 2.
Thevalve stem 20 for the valve'head extends downwardly through the chamber 6 and is therein out of'contact with all parts to which it could become stuck by corrosion.
rl`he stem is formed with lengthwise extending ribs 21, the stem being of reduced crosssectional area between the ribs. The foot of the valve stem is entrant in, and passes downwardly through the centerv hole 22 of the nut head 23 of an upstanding bracket 24; the head 23 of which is eXteriorly threaded at 25 for connection with the interiorly threaded bottom opening of the head, the lower end portion of which has its wall appropriately thickened at 26 to' permit the screwing of the bracket nut head into it, and for formation of a hole for a set screw 27 by means of which the bracket is kept fixed to the head. The bracket carries a collapsible valve locking device comprising a pair of supplementary wings 28 whose outer ends are connected by fusible metal 29, each wing having a bearing 30 at its head end and the two bearings 30 being alined. The bracket is formed with an elongated clear space 31 between its head 23 and its under end; and after the collapsible valve locking members are fusibly connected together, they are inserted between the under end'of` the valve stem andthe upper side of the under bracket end 32, when the bracket head may bel screwed` into closer relation to the head sprinkler and thereby tightly lock the valve head packing against the valve seat formed on the under end of the supply or coupling pipe 10. After the parts are thus tightly assembled, the set screw 27 is homed to prevent the valve lock carrying bracket from loosening upon the head; and in such tight assemblage, the valve head and the stem are out of such near position to other Darts as to make sticking of the valve in consequence of corrosion of opposed metal parts impossible for however lon@r a time the head as a whole is installed, prior to a fire. Melting of the fusible metal causes the valve locking members to collapse under the pressure of water in coupling pipe l0 and on the valve.
The collapsible valve locking wings 28 prefeiably extend horizontally outward of the Vvalve lock carrying bracket; the wings being opposedly recessed at 33 inwardly of the fusible metal 29, and the vertical head eX- .tensions 34: of the wings having their opposed ends 35 abutted ofi a vertical line through the valve stem and bearings 30 which are not only alined one withvanother but with the axis of the upstanding valve stein. The outlets 2 are formed by outwardly projecting curved walls 2a extending beyond the main wall of the nozzle or head and open into exterior recesses 2b having 0pposed horizontal side walls 2", and aibottom wall 2d. By this construction, the water is better hurled horizontally from the rotating nozzle or distributer head whichV is shown with four such circumferentially disposed discharge outlets 2, each of which is troughed outwardly of the discharge end of a. wall a2.
What I claim is:
l. In a rotary distributer head or nozzle provided with water escape openings formed to effect rotation of the headl or nozzle by force of water under head flowing through the openings, the combination of an exteriorly flangedV supply pipe; anti-friction balls on the flange; a chambered, rotatable, distributer nozzle formed with an interior rib projecting from its inner wall and inclosing a central, valve head receiving opening; the upper, inner margin of the rib being opposed to the ball carrying pipe flange, the nozzle having an annular flange extending upwardly of the rib; the flange being threaded for connection with a ball retaining ring, a ball retaining ring having a center bore inclosing the supply pipe; the valve head being of lesser crosssectional dimension than the cross-sectional dimension of the valve head receiving opening within the rib for formation of a corrosion preventing clearance between the valve head andthe inner wall of said valve head receiving opening, andthe valve head having a stem eX- tending outwardly through the nozzle wall for engagement with valve locking means; and valve locking meanscomprising a col` lapsible structure having aY plurality of parts held disintegrably together by fusible solder.
2. In the combination set forth in claim l, said discharge openings being formed through said rib and having outlet walls projecting beyond the main wall of the nozzle, such wall being eXteriorly recessed at the mouths of the discharge openings to form troughed water escapes.
3. A revoluble, chambered distributer head or nozzle provided with water escape Openings formed to effect rotation of the head or nozzle by force of water under head flowing through the openings, in combination with a supply pipe having a flanged entrant in said chamber for discharge therein; a bodily movable valve head for the discharge end of the supply pipe; Aand disintegratable means comprising fusibly solderedv members for holding the valve against the discharge end of the pipe until the fusible solder melts, with thefvalve head out 0fV near contact with all metal except the pipe end; the distributer nozzle being mounted revolubly on the flanged end of the supply pipe.
Signed at New York city in the county of New York and State of New York this 10th day of'May A, D. 1920.
