To @ZZ ohm/t it nifty/0071.012770.-

le it known that l, JOHN E. PnUNrv, ot' Baltimore, in the State ot lllaryland, have in- 'vented certain new and useful Improvements in lEire-Iilxtinguish in Apparatus, or Apparatus t'or the lllaniimlation ot' a l'l'ose lipe or Nozzle; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled` in the art to which it appcrtains to make and use t-hc same, reference being had to the accompanying drawings, and to the lets ters ot' reference marked thereon, which form part oit' this specilication.

My invention relates to a .tire-extinguishing aplntratns and apparatus .for the elticient and convenient manipulation of a hose pipe or nozzle ol' any required size in positions and under circumstances where such use has been heretofore dil'ticult or impracticable, espeeially ior the purpose ot' rendering practicable the use ot' large streams under great pressure and at considerable elevations. It may be used in connection with watcrtowers,

' stamtppes, tire ladders or trucks, which latter can be provided with this apparatus, in addition to thei r ordinary equipment, with little additiomil weight or imfonvenience, and greatly add to their et'lieiency and service in case ot' tire.

Much dil'ticulty has heretofore been experienced in the handling and manipulation of hose pipes and nozzles trom the recoil or retroactivo t'orce oll the water driven through hose at such pressure as .is necessary for efiiectiye [ire-servico, this recoil or retroactive force being generali)v proportioned to the amount olf divergence l'rom a direct line of the hose pipe or nozzle. This is particularly experienced in eases where the hose pipe or nozzle has been used at any considerable elcvation from the ground, as o i the tops of ladders, water-towers, the.

'lhe object ot my invention is to neutralize or counteract the Iforce ot' this recoil or retroactive force, and thereby enable tiremen to use their lire apparatus to reach places now practically inaccessible in time ot' great con- `tlagrationssuch as the interior ot' high and deep buildings-and also to regulate, control, and direct the st -ream of water from the hose pipe or nozzle with ease and certainty. l propose to accomplish these objects by the use of a pipe or a system of pipes, thrmigh which the water from the tire-engines or other sources is carried, and from which the water is radially ejected through slots or orices therein on all sides thereof into an auxiliary chamber rotating' freely upon such pipe and covering or embracing all of said slots or oriliees, such auxiliary chamber being also supplied with a nozzle loading therefrom and through which the water is discharged, said auxiliary chamber being movable and con trolled by screws, as shown in the drawings, or other equivalent means, said auxiliary chamber being also supplied with a bafleplate located near the opening from said chamber into the nozzle, to equalize the pressure in said chamber in. all directions.

illy invention itfurther consists in certain novel features oi' construction and combinations ot" parts, more vfully described hereinafter, and particularly `pointed out in the claims.

Referring to the accompanying drawings, Figure l is a side elevation of the device as attached to a stand-pipe. Fig. 2 is an edge elevation el' the same.- Fig. 23 is a vertical longitiulinal section. Fig. di is a vertical seetion taken on a plane at right angles to the plane ol' the section in Fig. 3. li 5 is a side elevation of the apparatus carried by a tripod or suitable standards, the apparatus, when mounted and constructed in this manner, being adapted li'or street purposes. Fig. G is a top plan oi? the form shown in Fig. 5; and Fig. 7 is a horizontal section taken on line of Fig. 5.

In the drawings, the reference-letter A indicates a continuous pipe or cond uit located at the top ot' a stand-pipe, water-tower, ladder, or the like, and provided with a short hollow neck or chamber, a, which extends centrally and downwardly from the lower side of the pipe or conduit, and at its lower end is jointed or swiveled in the upper end of the main hollow base a,which is divided at its lower ond into any desired number of branches to communicate with thel wa ter hose or pipes. It will be seen that the water passes from the hollow base into the hollow neck u, and from thence IOO it passes into the pipe or conduit, where its volume is divided, and passes upwardly in two equal streams which unite at the center of the upper horizontal portion of the pipe or conduit, and is discharged radially through a series of slots and apertures in said conduit into the auxiliary chamber E.

rlhe downwardly-extending neck a is connected with the hollow base a, to form a tight joint, and to allow the supporting-neck a and the pipe or conduit A, supported by the same, to freely turn or rotate horizontally. Between the bottom side of the pipe or conduit and the upper end of the hollow base a the supporting-neck a is provided with gearing B, horizontally surrounding its outer peripliery.

A shaft or spindle, 13, is horizontally journaled, opposite the gearing B, in suitable brackets'. Said shaft is provided with a screw or worm, C, adapted to mesh with the gearing surrounding the supporti n g-neck a of the pipe or conduit A.` One end of the shaft B is extended beyond the brackets in which it is j ournaled, and is provided with a chain or hand wheel, C, as desired, and according to whether the apparatus is placed a distance from the ground or near the ground within easy reach of an operator. Vhen the nozzledirecting apparatus is located a distance from the ground, the chain-wheel is used, and is operated by a chain, D, or other suitable means,

. engagin thesame and extending down wardly, and by which the apparatus can be rota-ted horizontally from the ground, and the chainwheel and shaft are protected by a casing and shield, D', carried by said brackets, and surrounding the shaft and extending over the wheel. An auxiliary chamber E surrounds the upper horizontal portion of the pipe or conduit A, having a discharge pipe or nozzle opening or extending therefrom. Said auxiliary chamber surrounds, embraces, and forms an annular chamber around the slotted or perforated portion of said pipe or conduit; hence the water from the pipe or conduit is radially discharged in all directions into the annular or auxiliary chamber, and from said chamber the water is discharged tlirough its nozzle, which may be of any desired :form or kind. The outer periphery of said auxiliary chamber is provided with vertical gearing or a segment, F7 as shown.

A horizontal shaft, F, is journaled in the open center of the pipe or conduit in suitable lugs or bearings extending upwardly from the upper side of the lower horizontal portion of pipe or conduit A, and so that its longitudi nal axis will fall in the vertical plane of the auxiliary chamber E. vided with a screw or worm, G, adapted to mesh with the segment F, and one of its ends is extended beyond the bearings of the shaft, and is provided with a chain or hand wheel, C2, as desired,.and the shaft and wheel are protected with a casing and shield, H Il', in a similar manner with the shaft and wheel for `horizontally turning the apparatus, and the The shaft F is pro-` wheel .is provided with a chain extending downwardly, whereby the auxiliary chamber, when at any elevation, can be vertically adjusted from the ground; or when the apparatus is mounted upon standards and adapted for street purposes, as shown on Sheet 3 of the drawings, the chain is dispensed with, and the wheels for vertically and horizontally operating the nozzle can be operated by hand.

rlhe auxiliary chamber IE freely rotates or turns upon the upper horizontal portion of the pipe or conduit when the shaft F and connecting-gearing are operated, and a water-tight joint between the conduit and chamber is effected by the packing-rings J, embracing the conduit and bearing against the adjoining portions of the chamber and conduit, and said packing-rings are held securely and tightly in position by the adjustable retaining-rings Z', embracing the conduit and ad justably secured to the chamber. Z indicates a ring adjustably embracing the conduit and adapted to be adjusted to or away from said chamber to prevent lateral motion of the chamber and take up wear of the parts.

A bathe-plate, L, exten ds tran sversel y a cross the interior of the auxiliary chamber E and between the slotted or perforated portion of the pipe or conduit and the inner end of thel discharge-nozzle leading from the auxiliary chamber, the object thereof being to equalize the pressure of the water in the auxiliary chamber.

In Figs. 5, (l, and 7 the apparatus is shown mounted upon suitable hinged and jointed standards, g g', pivoted at their upper ends to the hollow base a', and each of said standards is preferably formed in two sections pivoted together, and the standards are held together by the braces or hooks j", pivoted to each leg and provided with a hook portion engaging a lug or pin on an adjoining leg. Thus it will be seen that when it is desired to transport the device the standards or legs can be folded in together and in a small compass. The nozzle, when mounted in this manner, is especially adapted for manipulating and throwing large streams of water.

The great advantages and further operation of my device will be ful-ly obvious to those expert in the art to, which it relates.

I t is clearly evident that numerous slight changes might be resorted to in the form and arrangement of the various parts described without departing from the spirit and scope of my invention; hence I do not wish tolimit myself strictly to the precise construction herein set forth; but consider myself entitled to all such slight changes.

It should be observed that the terms vertical continuous are used for convenience, as the supply -conduit can be of any desiral'ile shape or size to permit of arotary adjustment and form a bearing for the rotary chamber into which the wateris discharged.

Ido not herein broadly claim the combination, with a revoluble cylinder having a de- IOO IIO

livery-tuyere, of two pipes having their delivery ends arranged opposite to each other and in axial line "of and forming the bearing for said cylinder, or of one pipe forming a bearing for said cylinder and provided with a series of equallyspaced peripheral outletports opening into the same and supply-pipe connected respectivelytothe opposite ends of said pipe.
