UNITED STATES JOHN GILSENAN, OF NEW YORK, N. Y.Y

NOZZLE.

Application filed october 17, 1921. Serial No. 508,283.

To all whom t may concern: A

Be it known that I, JOHN GiLsENAN, a citizen of the United States, and a resident of New York, county of )New York, and State of New York, have invented certain new and useful Improvements in Nozzles, of which the following is a specification.

This invention relates to an improved nozzle whichris adapted to be used in locations where it is either impossible for firemen to remain, or where it is only necessary to install a pipe for wetting down purposes, and is designed to be caught over a window sill, elevator openings, cellar openings and similar situations, and is `securely held in position, such holding being made secure when water under pressure is going through the hose.

The invention is illustrated in the ac companying drawing, Vin which Figure 1 is a side view of the device, showing part of a wall and a window opening. Figure 2 is a front view of the nozzle shown in Figure 1, and Figure 3 is a side view of the top part of a modified form of construction, a part thereof being shown in section.

The whole device takes on the general form ofan L-shaped structure, and I provide a pipe 10 which is bent, being bent substantially at a right angle so that the long arm 11 and the short arm 12 are provided, the long arm 11 having on its bottom a suitable coupling member 12 so that an ordinary hose line 13 can be coupled thereto, the short arm 12 having at its end means for Vseouring'it to an outlet pipe or nozzle 15 which can be secured thereto in any of the usual ways, usually by screwing it,on, so

, that different forms and sizes can be placed on the end of the bent pipe.

A hook 16 is provided, this usually being n formed by bending the end of a plate- 17,

the plate 17 being secur-ed to the short arm 12 in any suitable wa usually by means of collars 18 or the like, and I prefer also to bend the endV of the plate, as at 19, to form a support for the elbow of the pipe 10, and I place a pollar 20 or its equivalent at the extremity of the plate to grasp and hold the pipe 10.

In'many lire situations, very often on re escapes and also on straight walls where ladders have been raised, firemen can not remain on account of dense .smoke or llames bursting from windows, and it is necessary to direct water through such window openings and on to the lire. In such cases the pipe 10 is taken up to the place where it is to be installed, for instance, overa window sill into a window opening, and the length of the pipe 10 is suiiicientso that a fireman ata considerable distance below the window can hook the upper end of thedevice over the sill to the position shown in full lines in Figure 1. The hose 13, if not previously attached, can now be secured in place and then the water is turned on.

When pressure is applied, by reason of the waterpassing through the pipe, very often a Vhigh pressure, the device is more securely locked in position andv steadied, since the lower end of the long arm 11 of the pipe kicks in, as at 21, and bears against the outer side oi' the wall, and the back pressure on the short arm 12 causes the hook 16 to be more tightly pushed against the inner tace of the wall 22 below the window opening.

If desired, the direction or" the stream can be slightly altered by grasping the lower end Voi the long arm of th-e pipe, or by means ot the hose 13, and the pipe can be swung to a limited extent laterally and to aV con` siderab-le extent from the outer face of the wall so as to direct the stream of water from the outlet pipe in diierent directions with in the building.

This description of the use of the pipe in a window opening is, simply for the purpose of making clear how it operates, and it will be understood that the device can be used with the long arm of the pipe horizontal, such as through a side wall, vaultlike, or through openings out in floors leading into cellars, and by means of a suitable nozzle, such asthe so-called goose neck nozzle 23, shown in Figure 3, a horizontal stream can be delivered from this horizontal situation of the long arm 11 of the pipe.

If a moreflexible use of the pipe, and consequently the nozzle, is desired, I may provide the plate 17 and the short arm 12 of the pipe with coacting means for securing such flexibility, and in the drawing I show a ball 24 seated inthe socket 25, and a suitable regulating nut 26 can be used to enclose the ball and either lock it in position or loosen it sufficiently to permit its being rocked,

and in this wayV the hook 16 is not disturbed from its position when it is caught over the edge of :in opening, but the pipe 'lf/ can be 'ont-letrpipe, seid outlet pipe (T h erin substantially et right angles to each swung in different directions by the above described ball joint.

The pipe is adapted for use in dangerous situations, Vfor instance, in grain elevators, where oaveins would i'reertons oi'? grain :ind Crush people working in 'the building, :ind such pipe can be installed in an opening in such grain elevators, and by ineens oi a ,goose neck nozzle 28, :is shown in Figure Ahe stream eenA be directed vertically into such elevators or the shafts thereof, as will be evident.

I Claim:

l. Ai'nozzle comprising` e portable rigid snbstentially right-angled pipe, and e hool en the inner sideoi'2 one oi 'its'aiins- 2. A nozzle eoinprisingr portable rigid reason of substantially7 right-angled pipefa hook on4 the inner side ofV one of its airins, :ind :in and the end or' thereon having the erin which has the hooi:

coaoting means for securingoutlet pipeV said erin. Y 89A nozzle comprising i porte-ble rigid pipe bent toforin a short firm and a lon other and a hook Aon the end of the short erinV and et its inner side.

4. A nozzle comprising i portable rigid pipe bent to -form :i short erm and a long Lef/Gelo min, e.. p`zite bent it one end to 'form :i hool;

end havin a ineens torseeuring it to the pipe so that the hook extends inward from the iree end oii the inner side of the short nrni, seid short erin having un outlet on Suid end, seid vlong erin extending below the hook.

5. A nozzle comprising :i rigid pipe bent to forni e short erin :ind :i long;r :irin substantielly :it right angles lo erich other, n plate bent :it one end 'lo torni :i hook, the snort erin of the pipe and the plate ol the hook having;` connections providing Vl'or :uljustnient between these elenienls.

6. A nozzle e'on'iprising:r :i rigid pipe bent to forni a short erin :ind n loner aren, :i plate bent et one end to forni :i hook, lhc short erin of the pipe :ind the plate hiivinfhr ele niente thereon which, when assembled. l'orm e ball `ioint whereb)7 adjustment oi" the pipo relative to the plate is provided.

7. A portable nozzle comprising` :1 rigid right-angled pipe. one :irin oit which provided on 'its inner side with :i hook extending toward the other arni und above the end of said other erin, whereby the other arm and the hook cnn engage :in element between them.

In testimony that I claim the foregoing, I have hereto set in v hand, this 15th (luy of October, 1921.

JOHN GILSENAN.
