FIRE FIGHTING APPLIANCE' Filed April 11. 1927 Patented Nov. I 12, 1929 UNITED STATES PATENT" OFFICE DENNI E oAnEY, or LAWRENCE, ASSACHUSETTS FIRE-FIGHTING- APPLIANCE Application filed April 11,

the stream against the ceiling. I On account of the small size of the opening in which the hose nozzlemust be held,xits proximity to the ground, andfor other reasons, it is often practically impossible to direct a stream from an ordinary nozzle to the points desired under these conditions. An appliance of this nature, which may be advantageously 5 employed under such conditions, is therefore a desirable part of a fire fighting equipment.

to provide a form of play-pipe and aholding means therefor, which will enable a stream to be easily'directed' against the ceiling or into the corners of a room'through a small opening at the ground level. Also to provide an improved form of play-pipe holding means which is adapted foradjustment in a manner to enable the nozzle at the end of the pipe to be easily and conveniently held in positions in which it couldnot be held effectively with the ordinary type of handle, and Which is furthermore adapted for use for the purposes of a handle under ordinary conditions, as well as the special conditions before referred to.

I accomplish these objects by providing a play-pipehaving its nozzle set at an obtuse angle thereto and having an elongated handle which is arranged to be secured thereto in a position, or adjusted thereon to a position in which it extends for approximately the length of the pipe beyond the hose cou- The primary objects of my invention are" 1927. Serial No. 182,566.

Fig. 1 is a, side elevation of a preferred embodiment of the invention, and

Fig. 2 is a plan view thereof, showing the same in several positions of use.

Fig. 3is a plan view showing the device in folded position and Figs. 4 and 5 are detail sectional views at lines 44 and 55 respectively of Fig. 3.

As shown in the drawings, a metal hose or play pipe 10 is provided having an ordinary hose coupling 11 at one end, for connecting the flexible fire hose 12 thereto, and, at the opposite end a nozzle 13 which is set at an angle of approximately to the pipe 10, the latter being straight and cylindrical in form. Two

brackets

14 and 15, which are identicalin construction, are provided, each consisting of anannular sleeve having a pair of oppositely disposed arms extending divergently therefrom. The sleeve portions of said brackets are fitted on the pipe 10, the bracket 14 being slidable thereon, throughout its entire length and the bracket 15 being secured thereto by any suitable means, asby a set screw 16, in close proximity to the coupling 11; The bracket 14 also has a set screw 17 therein, which is adapted to bemanually operated, so that it may be readily locked in any position to which it may be adjusted. The

set screws

16, 17 are located midway between thebracket arms inwhat may be considered as the upper sides of the brackets, the side in which they are located being uppermost when its appliance'is in use. A pair of parallel rods 18, preferably of hard WOOCl, are securely fastened at adjacent ends in apertures 19, formed in the arms of the bracket 14, and are extended through similar apertures in arms of the bracket 15, in which they are slidable. A handle 20 is secured to the opposite ends of the rods, at the opposite side of the bracket 15 from the bracket 14. As thus arranged, the rods 18 are held inparallel relation to each other and to the pipe 10 and equidistant from the latter and the bracket 15 is secured on the pipe 10 in such a'position, with relation to the position of the nozzle 13, that the rods are held somewhatabove the level of the pipe, when it is held horizontally, with the nozzle projecting upward in a vertical plane, in which position the rods, if extended, would be held at opposite sides of, and equidistant from the nozzle. The sleeve portion of each

bracket

14, 15 provides a cylindrically formed, or transversely rounded face between its arms, at the under side thereof, on one or both of which the pipe "10 is supported" when in use, as hereinafter described.

WVhen the parts are in what may be considered the normal or folded position, the bracket 141- is held close to the nozzle 13 and the handle 20 close to the relatively fixed bracket 15, as shown in Fig. 3, the bracket 14 being locked to the pipe by the set screw 17. In this position the rods 18 will be practically coextensive with the pipe 10 and will serve as handles therefor when it is to be'manuailly support-ed. If, however, it is desired to insert the pipe into a window opening and to direct the stream in various directions, from the sill thereof, and particularly upwardly, so that the stream will strike the ceiling of the compartment to which the window opens, the set screw 17 is loosened and the bracket 14, the rods 18 and handle 20 are moved back so that they extend over the hose pipe or beyond the end of the pipe 10 to which the hose is connected, as shown in Fig; 1, the

brackets

14, 15 being thus held. close together. Then thepipe is passed through the window. and so held that the transversely rounded. faces on the unc er sides of the brackets rest on the window sill. As thus supportedand held by manual engagement with'the handle 20, for rods 18, the pipe 10 may then be tilted vertically on the side as a fulcrum or swunghorizontally or rocked laterally on the supporting face of the sleeves towards either side, as indicated in Figs. 1 and 2, by moving the handlev and rods correspondingly, so that the stream may be directed against anypart ofthe ceilin or into any of the corners of the room. That is, as the nozzle 13 extends obliquely upward when the pipe is supported on the transversely curved under sides of the

brackets

14, 15, the stream will be directed towards the ceiling and when the pipe is rolled sidewise on said under sides, the stream may be directed horizontally in practically any direction by swinging the pipe on the fulcrum provided by the brackets. 7

Under these conditions, thehose will extend down from thepipe beneath the rods, so

that it will not interfere with the manipulm tion of the nozzle, as shown in Fig. 1..

When the pipe is supported in the manner indicated in Fig. 1, it may be easily held in position and directed in the different ways indicated by means of the rods and their connecting handle, the rods being spaced apart sufiiciently and the handle 20 being shaped in loop form to permit the rods to be swung down at each side of the hosepipe, and the transverse leverage provided by the location of the rods being such that the play-pipe may be easily rocked or rolled laterally on the supporting faces of the brackets and held in these positions.
