PROTEGTIQN-NOZZLE FOR FIRE-HOSE.

SANGER, a

resident ol the eitj,T oi New York, horouoh ol' il anhattan, in the county and State oi New l erh A invent-ed new and lniproved grote ,i i- Nozzle for l Jello-se, ol' which the ollowing is e full, cle i, -d exact description.

This invention relates to nozzles such as used en lire l- Vfor directing1 a stream ol Water into lire.

rlhe ohiect ol the infention is to produce a hose nozzle ot this class having a corn tion which 'will enahle protecting Water to he thrown out troni the nozzle f between the treinen and the fire, that tne- 'F 'einen 'will he protected .troni the sniole and injurious gases of combustion; and to arrsnge the arts ot the nozzle in such Way that this pi iting sheet will not have the erllect ol producing a draft toward the lire.

The invention consists in the construction and conihination of parts to he more lull)T described hereinafter and particularly set forth in the cla' ns.

Reference is to he had to the secon vanving drawing orining a part ot this speciiication, in which the view is a longitudinal central section through a hose nozzle constructed according to injv invention, certain parts heing hroken away and shown in elevation.

Referring more particularly to the parts, l represents the hase or huh ol the nozzle, which is provided with internal threads 2 Wnich enable it to he attached to the ring at the end of the hose. rlhe body 3 of the nozzle is slight-lf,T conical so as to taper toward the outer` end of the nozzle. At the neck 4 Where the nozzle is of sinallest diameter, a inain tube 5 is torined which is held on the central axis of the nozzle by means of integral Webs 6 Which connect With the outer Wall, as shown. l? ejfond this point the outer Wall of the nozzle ilares outwardlj so as to forni a conical shell 7, the largest diameter of the shell being disposed toward the outer end of the nozzle. At its outer edge this conical shell is provided with an oum'ardl)T projecting flange or guide lip 8 which is disposed in a plane at right angles to the central aXis of the nozzle, as indicated. ln the conical shell 7 there is received a cone or cone plug 9, and provided With a threaded opening l at its sniall end Which is received on the threaded neck ll of the inain tuhe. She outer edge of the cone 9 is provided with an outwardly Specification o Letters loatent.

projecting llanfge or guide lip l2 which is disposed opposite to theV t?, and this flange also lies in s plane rr :it angles to the axis Ofi the outer tace of the 'l seated which closes the O positoly disposed hanare prof-filled this point, i openssl. handles to enahle the plug to ne rotated. he tuhe passes through an opening,` l5 in a. dish or plate i3, and at this provided witl threads l@ upon nut l received, as indicated. Ee'- nut Washer l is provided and wash r seats the inner end of a L f the nozzle, seid tip hesoc red on a pine threaded nipple 20. @n the threaded neel; ll a stop nut 2l is provided, and on the inner lace of said stop nut a Wester 22 provided, against which the inner end elZ the cone 9 v.' ien it is ad- ,iusted outward j. to its outer liinit or Wide opevn position. v llilhen the nozzle is in operation, 1n addition to the inain streain which passes through the inain tuhe 5 and which is directed upon the lire, an annular streani passes through the neel l, as indicated hy the arrows, and troni this point this stream passes outwardly along a conical duct 23 which is formed Within the shell '7 adjacent to the face oi the cone lilhen this conicallT diverted strcain arrives at the llanges 8 and l2 it is directed hy thein in a plane at right angles to the axis of the nozzle, and in this Way a thin sheet of Water is projected between the rirenien and the lire. By adjusting the cone on the threaded neck il, the thickness of this sheet or Wall of Water can loe regulated as desired.

A hose nozzle constructed as described will evidently protect firemen from heat, sinole, and gases of coinhustion. This nozzle, furthermore, will not tend to produce a draft in the direction of the nre even it used just Within a nfindoxv through which the hose passes to the interior. Bjv projecting the sheet of Water at right angles to the axis of the inain stream, it Will normally be disposed in a substantially vertical plane or tip rear wardlgT at its upper edge and will have little or no tendency to draw the air toward the lire.

Attention is called to the fact that the annular conical duct 23 which leads the Water to the guide lips 8 and 12, is oonstricted in the direction ot' the lips. This constriction iS l is gradual and is brought about by the gradual convergence of the walls of the cone and the shell. This arrangement tends to reduce the area of the stream near its point of delivery, and tends to close any gaps which may have been formed in this stream by the web 6. j

Having thus described my invention, I claim as new and desire to secure by Letters Patent,-

l. A hose nozzle having a bodywith a conical shell connected therewith, said conical shell having an outwardly projecting flange with a flat guiding face disposed in a plane at right angles to the aXis of said body, a centrally disposed main tube adapted to throw a main stream, and a cone carried on said main tube, the face whereof lies adjacent to said shell, said cone having an out- Wardly projecting flange lying opposite to said first flange and having a flat guide face disposed in a plane at right angles to the axis of said body, said main tube being connected with said body beyond said conical shell whereby the stream 'flowing in the space between said shell and said cone is unobstructed, said cone and shell converging in an outward direction and constricting the duct therebetween tending to close the gaps caused by said webs.

2. A hose nozzle having a body with an outwardly flaring conical shell, a main tube mounted centrally in said body and having Webs connecting the same with said body beyond said conical shell, said tube having threads thereupon near its inner end, a cone mounted on the threads of said tube and received in said shell, said cone and said shell having outwardly projecting guide lips disposed adjacent to each other, a nut on said threads, seating against the inner end'of said cone for adjusting the same, a di'sk seating on the outer end of said cone, said tube having a thread adjacent to said disk, and a nut i mounted on said last thread seating against said disk. Y

3. A hose nozzle having a body with a outwardly flaring conical shell, a main tube mounted centrally in said body and having webs connecting the same with said body beyond said conical shell, said tube having threads thereupon near the inner end thereof, a cone received in said shell and having a threaded opening at its inner end received on said threads, a stop nut mounted on said threads and adapted to limit the outward movement of said cone, a disk seating on the outer end of said cone and having an opening through which said main tube passes, said main tube having threads at the outer end thereof, and a nut on said threads seating against the outer face of said disk.

4. A hose nozzle having a body with an outwardly flaring conical shell, a main tube mounted centrally in said body and having webs connecting the same with said body.

beyond said shell, a cone mounted on said tube, said cone and said shellhavingoutwardly projecting guide lips, said cone havin handles on the ends thereof projecting su stantially parallel with the axis of said nozzle, and a disk seating on the end of said cone and `having openings through which said handles pass, said tube having a threaded connection with said cone for adjusting said cone.

In testimony whereof I have signed my' MILTON J. SANGER.
