NOZZLE.

Specification of Letters Patent. Patented luay 1G, 1911.

Application filed November 19, 1910. Serial No. 593,133.

To all whom it 'may concern:

Be it known that I, MILTON H. HART, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Nozzles, of which the following is a specification. l

This invention relates to improvements 1n water-nozzles, designed for use by fire departments, and the like.

The invention relates particularly to 1mprovements in the devices shown and described in Letters Patent of the United States numbered 550643, bearing date December 3, 1895.

The object of the invention is to provide a nozzle which is especially adapted for mounting upon any suitable fixed base, and which may be readily adjusted and set 1n different positions and to dierent angles, so as to throw the stream of water in any direction.

A. further object is to provide simple and effective means for locking or securing the nozzle in the different positions in the readiest and quickest manner; and a further object is to provide novel and effective means vfor preventing expansion of certain parts,

and for packing the several joints of the nozzle, so as to prevent leaking while the device is operated under a high waterpressure.

My invention and the novel features thereof may be more readily understood from the detailed description which follows, and by reference to the accompanying drawings, in which- Figure 1 is a side elevation of my device, showing the method and means for adjusting the same to different angles. Fig. 2 is a front elevation of the device. Fig. 3 is a central vertical section, taken through Fig. 1. Fig. 4 is an enlarged detail section taken on line 4-4 of Fig. 3.

Similar characters of reference designate corresponding parts throughout the several views.

In the drawings, 2 represents a Y-shaped or forked supply-pipe, having its lower end provided with a groove 3 for forming a swivel connection with any suitable fixed or stationary base (not shown) by means of which the nozzle may be rotated. The upper ends of the forked pipe are formed unto like concentric hollow cylindrical portions 4 and 5, which open into the branches of said pipe, for the passage of water. Both ends of the cylinders 4 and 5 are open, and

their outer ends are internally threaded, to

receive screw-caps or heads 6 and 7 which may be screwed in against a gasket or packing 8, for providing` water-tight joints at said points. To further hold the caps 6 and 7 against yielding outwardly and breaking the seal, when subjected to a high waterpressure, I employ a stay-bolt or rod 9, one end of which is preferably rigidly anchored in or secured to one of the caps, as 7, the opposite end of said rod extending through both cylinders 4 and 5, and then passing loosely through a perforation in the center of the other cap, as 6, the free end of the bolt being threaded to receive a nut 10, employed for drawing and holding the caps in place. To prevent the escape of the water through the opening in cap 6, I provide an annular packing or gasket 11, which is disposed in oppositely facing recesses formed in the cap 6 and in the nut 10, as best seen in Fig. 3. By the use of the stay-bolt 9, lighter weight caps may be used and still afford adequate strength.

The openings in the inner ends of the cylinders 4 and 5 are contracted by means of inturned flanges 12, and are spaced apart to receive the annular lower end 13 of a nozzle-piece or pipe 14, which is disposed at right angles to, and closely fits between, the cylinders 4 and 5, and which with the said parts form a common central horizontal water-space or chamber, which may be generally designated by the numeral 15. The water flows upwardly from a base or other source of pressure through the passage 16 of supply part 2, then divides and passes on upward through hollow branches 17 and 18 of part 2, thence into the common chamber l5, from whence it flows upwardly again as a smgle stream through pipe 14, into pipes 19 and 2O attached to pipe 14, and is nally discharged at 21.

To make a hinge or pivot connection between the annular part 13 of pipe or nozzlepiece 14 and the cylinders 4 and 5, I provide annular bushings 22 and 23, the facing inner ends of which are externally threaded for screwing into threaded lateral openings 24 of the part 13, where they are preferably locked and held from accidental loosening by set screws 23. The bushings 22 and 23 serve as trunnions for the pipe 14, which have their bearings at 25 in the flanges 12 wardly and backwardly turned flanges 26,'

for forming annular grooves or gutters 27, in which is disposed packing-rings of any suitable material, as 28, which are employed for preventing the water from escaping from the chamber 15 to the outside of the device at or through the joints 29, and interfering `with the convenient and comfortable handling of the device. In order vto elfectually prevent the leaking of the water through the said joints, the outer surfaces of the flanges 12 are recessed, as at 30, and the vertical walls of the recesses are corrugated, and the corresponding surfaces 31 of the grooves 27 are also corrugated, for the purpose of increasing the bearing or contact surface of the packing ring 28. Under this arrangement when the bushings 22 and 23 are screwed into place, they compress the packings 28,V between the annular corrugated seats 30 and 31, and thus effectually prevent the seepage or leaking of the water from chamber 15.

The packing 28, in the' present device, is disposed within the cylinders 4.and 5 and between the ,body of water which fills the chamber 15 and the joints 25 and 29, and in this particular differs materially from the method ofapplying theA packing as shown and described in the former patent referredto. Under this arrangement the water cannot reach either the bearings 25, or the joints 29, without passing around or through the packing rings 28, which of course,is practically impossible, owing to the fact that the packing is compressed tightly between the corrugated surfaces or seats Vof the gutters 27 and the recesses 30 of flanges 12. After the parts of the .device are all assembled in place, the tightening up of the nut 10, may also serve to draw and hold the cylinders 4 and 5in close frictional contact with the part 13 of the nozzle-piece 14,

and in this manner coperate ,with the packing rings 28, for preventing the leaking of the lwater through the joints 29. The bushings 22 and 23 are preferably made to afdiameter slightly less than the bore of the cylinders 4Y andV 5, so that they may be readily inserted through the open ends and screwed into place, before the caps 6 and 7 are apy plied.

lrelativelyto the bifurcated part 2 and the cylinders 4 and 5, by rocking, swinging, or turning the same on the bearings 25 and joints 29, for throwing the stream of water in any direction. Owing to the high pressure used by modern fire departments and in order to facilitate the safe and Aeffective handling of the nozzle during a fire, it is desirable to lock or otherwise securely hold the nozzle in the different positions. To accomplish this end, I provide a rod 33, which is pivoted between the lugs of a bracket 34, by a pin 35. The rod then extends upwardly alongside of the pipes 14 and 19, where its free end passes through and is adapted to play reciprocall'y in a guide 36, which may be swiveled at 37, to a band or ring 38, which is mounted on the pipe 19. A thumb-screw 39 is threaded into the guide 36, by means of which the rod 33 may be locked for holding the nozzle in the different positions. By unscrewing the thumb-piece 39, the nozzle may be swung by hand either tothe right or, left, as indicated by dotted lines in Fig. 1.

Having thus described my invention,what l claim as new and desire to secure by Letters Patent, is- Y 1. The combination with a bifurcated supply-pipe, and an adjustable nozzle-piece disposed concentrically between flanged portions of the branches of said pipe, of a pair of cylindrical bushings threaded into saidl nozzle-piece, each bushing having an eX- ternalv flange arranged to form ani annular groove facing the lange of said supplypipe, corrugated seats formed in the flanged portions of the supply-pipe, corrugated seatsl formed in the grooves of said bushings, and a compressible packing disposed between said corrugated seats for preventing' the leaking of the device.

2. A bifurcated supply-pipe having Con-A centric cylinders formed on the branches thereof, each cylinder having an inturned flange for contracting the opening in one end, annular corrugated seats for receivingV a packing formed in said flanges, a nozzlepiece operatively disposed between the cylinders of said supply-pipe, bushings piero-- ing the flanges of the cylinders vand connecting to the nozzle-piece, each bushing having a flange arranged to form a groove facing the flanges of said cylinder, one wall of each groove formed into an annular cor-4 rugated seat, and a packing ring disposed in the groovev of each bushing and compressed between said corrugated seats for preventing the leaking of the device.

3. A nozzle, comprising a forked supplypipe Vhaving concentric cylindrical portions formed on the branches thereof, an annular nozzle-piece operatively disposed between said cylindrical portions and forming therewith a common water-chamber, a pair of caps for closing the opposite ends of said chamber, means for holding said caps in place and for effecting a water-tight joint between the cylindrical portions of said supply-pipe and said nozzle-piece, a pair of hollow trunnions for pivotally connecting said nozzle-piece to the cylindrical portions of said supply-pipe, said trunnions having one end formed into an annular corrugated groove facing the nozzle-piece and a packing-ring surrounding each oiE said trunnions and disposed in the corrugated grooves adapted to be compressed against portions of the supply-pipe for preventing the water in said chamber from reaching the jointy between said nozzle-piece and said supplypipe.

Ll. In combination, a bifurcated supplypipe having annular watenways formed on the branches thereof, an annular nozzlepiece operatively disposed between and concentric to said waterways and forming therewith a common water-chamber, a pair of bushings connected to the opposite sides of said nozzle-piece within said water-chamber, adapted for pvotally connecting said nozzie-piece to the branches of the supply-pipe, each of said bushings having a flange arranged to form an annular groove facirw the nozzle-piece, a corrugated Vseat formed in each flange of the supply-pipe, corrugated seats formed in the grooves of said bushings and a packing-ring disposed in the groove of each bushing, capable of being Compressed between the corrugated seats of said bushings and said supply-pipe for prevent-- ing the leaking of the device.
