VINCEN P. MGVOY, 0F MOBILE, ALABAMA.

HosENozzLE.`

To aM whom it may concern.'

Be it known that I, VINCEN P. MoVoY, a citizen of the United States of America, and resident of Mobile, in the county of Mobile and State of Alabama, have invented certain new and useful Improvements in I-Iose- Nozzles, of which the following is a specification.

This invention relates to certain new and useful improvements in hose nozzles and it` has for its objects among others to provide a simple form of nozzle provided with means for producing an effective stream.

I aim further at improvements in the details of construction whereby improved results are obtained, such as providing for the control of the admission of air between the streams, the provision of a strainer of sufficient area to prevent trash or othersubstance from interfering with the outer stream and the provision of an extension tube or sleeve to lengthen the nozzle when necessary, and other minor details which will be more fully hereinafter set forth.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.

The invention, in its preferred form, is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which- Figure 1 is an elevation of a nozzle constructed in accordance with my present invention. Fig. 2 is a substantially central longitudinalsection through the same. Fig. 3 is a cross section as on the line 3-3 of Fig. 1. Fig. 4 is an end view. Fig. 5 is a side elevation on a smaller scale showing an extension. Fig. `6 is a detail in longitudinal section with portions broken away. Fig. 7 is a similar view showing the parts in a different position.

Like numerals of reference indicate like parts throughout the different views.

Referring to the drawings, 1 designates the outer casing or body portion of the nozzle. It is formed at one end with the enlargement 2 internally threaded, as at 3, for .attachment to the hose or an extension soon tor be described incase such is employed. The enlargement 2 is provided with studs,

as 4,for coperation with a Spanner, as

shown. The casing` or `body portion of the nozzle may or may not be tapered toward Specification of Letters Patent.

nut or end cap 6 which may or may not be corrugated or roughened for ease of manipulation, the outer end of said nut or cap portion being reduced, as seen at 7, and in some instances may be provided with an annular channel 8 with which communicate the apertures 9, as seen in Figs. l, 2 and 5, for the purpose of introducing atmospheric air at a point adjacent the outer stream soon to be described. In some instances, however, this annular channel and the apertures leading thereto may not be present.

9 is a jam nut sleeved upon the threaded end portion 5 of the casing or body portion of the nozzle, serving to maintain the cap or end piece in its `adjusted position, ina well known way.

W'ithin the casing or body proper 1 of the nozzle is disposed a concentric nozzle 10 which may be retained therein in any suitable manner, in the present instance being shown as provided at apoint substantially where the taper of the outer casing terminates with an annular boss or enlargement 11 cxteriorly threaded, as at 1Q, and provided with a shoulder 13, which threaded portion engages the threads 14C of the sleeve 15 introduced between the inner nozzle 10 and the outer casing 1 and providing the annular air space 16, as seen best in Fig. 2. This, however, is but one of the many ways in which these parts may be retained in relative position. The sleeve 15 may like- `wise be retained in position in any suitable manner. In the present instance it is shown as provided at its inner end with an annular enlargement; or boss 17 which at substantially diamctrically opposite points is formed with depressions 18 screw threaded, as at 19, the said screw threads being in alinement with the screw threads 2O of the outer casing 1, as shown best in Fig. 3, and engaging these threads of the casing and the sleeve are the bushings or ferrules 21 which, as will be readily understood upon reference to Fig. 3, serve to retain the sleeve andeasing in relative positions, yet allowing of ready separation when necessary, also ease of assembling when setting up the nozzle. The sleeve 15 is formed intermediate the bosses 17 with longitudinal channels `22, as

clearly seen in Fig. 3, which allow for the passage of the water between the sleeve and the casing.

23 is a sleeve having threaded engagement with threads 24 on the casing l, as seen clearly in Fig. 2. This sleeve 23 serves to cover the openings 25 formed in the ferrules or bushings 21 and in the sleeve 15, as seen in Fig. 3, and which afford communication between the outer atmosphere and the passageway 1G, so as to admit-air thereto. The sleeve is provided with the perforations 26 which serve to admit the air to the openings 25 and yet prevent entrance of foreign substances as well as the shutting 0E of the inow of `air by the hand of the fireman grasping the sleeve. is seen in Figs. 2 and 3, the sleeve is enlarged in diameter interiorly between its ends, so as to provide an annular chamber 27 between its inner wall and the adjacent wall of the casing 1 so as to insure sufficient air space at that point.

ln some instances it is desirable to make provision against the entrance of trash or foreign substances into the outer passageway 28 between the outer casing and the inner nozzle 10. This may be accomplished in a variety of ways. ln the present instance l have shown a simple form of means for doing this, which consists of the tapered sleeve or thimble 29 having threaded engagement with the threaded inward eXtension 8O of the casing and its outer end supporting in any suitable manner the inner end of the nozzle 1G, the said sleeve. or thimble being perforated, as shown at 31, which allows suflicient water to pass therethrough into the annular passage 28. lf the perforated sleeve or thimble 29 is not present, the inner end of the nozzle 10 may be supported from the inner wall of the casing 10 in any suitable manner.

82 is the annular passage for the outer stream between the outer end portion of the casing 1 and the sleeve 15, see Fig. 2.

The outer end of the sleeve 15 is slightly expanded or flared outwardly, as seen at 33, shown in Figs. 2, 6 and 7, the taper 7 of the inner wall of the reduced portion of the cap or end piece coperating therewith to pro'- duce an important result. llihen the outer end of the cap and the sleeve are flush, as seen in Fig. 2, the course of the outer stream is concentricwith the `inner stream.` By adjusting the nut outward into the position indicated in Fig. 7, the course of the outer stream is deflected inward, as indicated by the arrows in said Fig. 7, thus shortening the throw of the stream, whereas by adj usting the nut back beyond the outer end of the sleeve, as indicated in Fig. 6, the course of the outer stream is deiiected outwardly.

l sometimes provide an extension to the nozzle, as indicated at 34 in Fig. 5. "When this is employed, its threaded end is engaged within the threaded end 3 of the casing 1 of the nozzle in a well known manner. This extension 34 may be provided with hand grips 35, as shown in F 5.

ln use with the nozzle attached to the hose when the water is turned on, itflows through the central nozzle 10 and through the outer surrounding passage 28 between the nozzle and the outer casing 1, passing through the channels 22 in the boss portion of the sleeve 15 and thence through the annular passage 32, around the sleeve and through the passage 35 between the outer end of the cap piece 6 and the outer end of the sleeve. At the same time air is drawn in through the apertures in the sleeve 23, if the latter be employed, and thence through the passages 25 into the annular air chamber 16, passingout between the inner and outer streams. The twostreams are thus separated by the intermediate volume of air. l have also found from vpractical experience that the nozzle thus constructed with the division of the stream with the intermediate air most effectually prevents popping and snapping.

From the foregoing it will be seen that I have devised a simple and efficient form of nozzle and while the structural embodiment of the same as hereinbefore disclosed is what l at the `present time consider preferable, it is evident that the same is subj ect to changes, variations'and modifications in details, proportion of parts, etc., without departing from the spirit of the invention or sacrificing any of its advantages. l, therefore, do not intend to restrict-myself to the exact construction hereinbefore described, but reserve the right to make such changes, variations and modiiications as come properly within the scope of the protection prayed.
