Nozznn Specification of Letters Patent.

Patented June '28, 1921.

Application filed August 15, 1918. Serial No. 249,928.

panying drawings, and tocharacters of reference marked thereon, which form a part of this specification.

This invention has reference, generally, to improvements in nozzles for use in connection with hose; and, the present invention relates, more particularly, to a novel construction of nozzles for attachment to a hose for throwing a stream of water, and combining with the nozzle means attached thereto in such a manner that a vacuum and a suction will be produced with the nozzle, and that thereby a fluid may be drawn into the nozzle and caused to intermix with the water prior to being forced from the discharging end of the nozzle.

The present invention, therefore, has for its principal object to provide a nozzle of the general character and novel arrangement and construction of the various devices and 'parts thereof, whereby the nozzle-may be used for varlous purposes; such as disinfecting and fertilizing purposes, for fighting fires in combining chemicals with a stream of water, for destroying germicides, washing purposes, destroying acid and other obnoxious fumes, and in some instances being ap licable-in condensing exhaust steam.

ther objects of the present invention not at this time more particularly enumerated will be fully understood from the following detailed description of the present invention.

With the various objects of the present invention in View, the said ginvention consists, primarily, in the novel nozzle hereinafter more fully set forth; and, the invention consists, furthermore, in the novel arrangements and combinations of the several devices and parts, as well as in the details of'the construction of the said parts, all of which will be more fully described in the following specification, and'then finally embodied in the clauses of the claim which are appended to and which form an essential part of the said specification.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a nozzle made according to and embodying the principles of the present invention; and Fig. 2 is a longitudinal and vertical section of the same.

, Fig. 3 is an end view of the nozzle, looking toward the discharging end, of the same; and Fig. 4 is a transverse vertical section of the nozzle, said section being taken on line 4.4: in said Fig. 2, looking in the direction of the arrows in said figure.

Similar characters of reference are employed in all of the above said described views, to indicate corresponding parts.

Referring now to the said drawings, the reference-character 1 indicates the complete nozzle, showing one embodiment of the principles of the present invention, the same comprising a main tubular member or element 2 which is internally screw-threaded,

at its respective end-portions, as at 3 and 4. Suitably screwed into the screw-threaded end 3 of the said member or element 2 is a suitably-formed coupling, as 5, preferably provided with an annular flange 6, or the like, between which and the end of said member or element 2 theremay be disposed a suitable washer, as.7, to prevent leakage at that point, as will be evident. Suitably connected with the said coupling 5, upon the opposite side of thefiange 6, in any desired manner, is the end-portion of a hose 8, substantially as shown in Figs. 1 and 2 of the drawings. I

, Suitably. screwed into the screw=threaded end 4 of the said member or element 2, is the screw-threaded end-portion 10 of another tubular member or element, as 9, the said member or element 9 being preferably formed with an annular off-set or-shoulder, as 11, and disposed between the said offset or shoulder and the end of said member or element 2 there may be another washer, as 12, of any suitable material, and to prevent leakage between the connected members or elements 2 and 9, as will be clearly evident from an inspection of said Fi .2 of the drawings. Upon its opposite en -portion or dischargin end, the said member .or element 9 is pre erably provided the member or element 9 by screwing it' thereon, as indicated at 15 in said Fig. 2. The sprayer-member or cap may, however, be otherwise secured in its mounted position upon the end of the member or element 9, as will be clearly understood. As.

shown, the main portion of the said sprayermember or cap is preferably concaved as at 16, and'is provided with a multiplicity of sprayer or discharging perforations 17 which are preferably suitably disposed in such a manner so that the discharge water, or the. like will pass from the nozzle-end, in the direction of the arrows at indicated in said Fig. 2. The central portion of the.

provided with an opening 21 in which is' fitted the lower portion of a tube 22, said tube being suitably bent in the manner of an elbow, the bent portion 23 of said tube extending into and terminating within the end-portion 20 of the tube 19.

Upon its free end-portion, the bent portion 23 of the tube 22 is suitably fitted with a ca 24 which has a perforation, as 25, forming an outlet for the purposes toloe presently described. The lower end-portion of the tube 22 projects from said opening 21 and is externally screw-threaded, as at 26, for screwing -in position thereon of a tubular fitting 27, over which may be secured the end of a piece of flexible tubing, as 28, forming a suction through which a disinfecting medium, a chemical, fumes, or the like are adapted to be sucked and conveyed into and through the tubes 22 and 19, when a stream of water is permitted to flow from the tubing or hose 8 into and through the nozzle 1. I

Having in the foregoing described the general construction of the nozzle, I will now'briefly describe its use as a vacuum siphon 'for disinfecting and fertilizing purposes, for use as a fire-extinguishing means, for ridding buildings, etc., of acid and other obnoxious fumes, or for condensing exhaust steam. R v

Whennsed for disinfecting, fertilizing, or fire purposes, the free end of the flexible tubin 28 is connected witha reservoir-or tank in which the proper fluid or mixture is contained, and the water through the hose 8 1s turned into the nozzle. Immediately the Water will pass through the space 29 formed by the'concentrically.

disposed tubular member or element 9 and the tube 19, the water passing through the perforations 17 in the direction of the arrows :0. At the same time, some of the water passes into and through the tube 19 around and about the tube 22, thus causing a vacuum at the perforated cap 24, whereby the disinfecting, or other mixture used, is drawn up into the tubing 28 and by suction caused to pass through the tube 22 and from the erforated cap 24, being thoroughly intermixed Within the tube 19 with the water passing through the latter tube. At the discharge-end of the main tubular element or member 9 increased suc tion is produced so that at this point a most efficient mixture of the fluid coming through the tube 19 will be made with the water or fluid coming through the tube 9..

When the nozzle is to be used for the purposes of ridding buildings, tanks, and the like, of acid or other obnoxious fumes, the tubing 28 is simply led into such building or suitably connected with the tank, and, when the water is passed into and from the nozzle, the objectionable fumes or gases are withdrawn in the manner hereinbefore described. In a like manner, the tubing 28 may be connected with a tank, or the like, into which exhaust steam is collected, the exhaust steam being Withdrawn in the manner hereinabove stated, and condensed with the supply of water passing from the nozzle, to be suitably collected for future use.

While I consider the arrangement and combination of the devices and parts as illustrated in the accompanying drawings, as the best for producing a most efiiciently operating nozzle, still I am aware that some changes may be made in'the general arrangements and combinations of the various devices and parts, as well as in the details of the construction of the same, without departing from the scope of the present invention as set forth in the foregoing specification, and as defined in the clauses of the claim which are appended thereto. Hence, I

do not limit my present invention to the exact arrangements and combinations of the several devices and parts as described in the said specification, nor do I confine myself to the exact details ofthe construction of the said parts, as illustrated in the accompanying drawings.

I claim 1. A mixing nozzle of the character and for the purposes stated comprising a pair of separably connected tubular elements, one of said elements being provided with a discharge-end, and the other element being provided' with means for its attachment to a hose or the like for admitting a fluid, into and through said connected tubular elements, an internally and longitudinally'disposed tube within and concentric with one ofv said tubular elements, saidtube being open at both ends, one of said open ends located directly at the discharge-end of said tubular element, said tube'having its other endportion extending into and terminating in the other tubular element, said tube being adapted to receive some of the fluid admitted into the connected tubular elements, said last-mentioned tubular element being provided in its side with an opening, an inlettube mounted in said opening, said inlettube having a bent portion extending into and terminating in said internally disposed tube at a point substantially back of the discharge opening thereof for carrying another fluid into said internally disposed tube, substantially as and for the purposes set forth.

2. A mixing nozzle of the character and for the purposes stated comprising a pair of separably connected tubular elements, one of said elements being provided with a discharge-end, and the other element being provided with means for its attachment to a hose or the like for admitting a fluid into and through said connected tubular elements, an internally and longitudinally dis posed tube within and concentric with one of said tubular elements, said tube being open at both ends, one of said open ends located directly at the discharge-end of said tubular element, said tube having its other end-portion extending into and terminating in the other tubular element, said tube being adapted to receive some of the fluid admitted into the connected tubular elements, said last-mentioned tubular element being provided in its side with an'opening, an inlettube mounted in said opening, said inlet-tube having a bent portion extending into and terminating in said internally disposed tube for carrying another fluid into said internally disposed tube at a point substantially back of the discharge opening thereof, combined with a sprayer-cap mounted upon the discharge-end of said first-mentioned tubular element and also connected with said internally disposed tube.

In testimony, that I claim the invention set forth above I have hereunto set my hand this 10th day of August, 191.8.
