Specification of Letters Patent.

Patented a1. 11,-1e1e.

Application filed October 28, 1918. Serial No. 260,049.

Girardeau, and State of Missouri, have invented new and useful Improvements in Holders for Portable Fire-Extinguishers, of which the following is a specification.

This invention relates to fire extinguishers and more particularly to those of the hand type and utilizing a chemical extinguishing agent. It is intended more particularly for use on automotive conveyances such as automobiles, tractors, motorboats, aeroplanes, and the like, and has for its principal objects. to detachably support the extinguisher in convenient reach of the driver and to provide for its operation while so supported and the distribution of the extinguishing agent to a place remote from the 1 .support,.whereby to'minimize the fire risk and to facilitate quick and efiicient action in combating a fire occurring in a place ordinarily inconvenient of access. Other objects and advantages to be attained will herein after more fully appear.

The invention consists essentially in a novel supporting device in which the extin isher is held thereon with suflicient sta ility to withstand the usual jarring and jolting motions to which it is subjected on the vehicle, and yet may be quickly removed therefrom should occasion require; said supporting device having a pipe connection with which the nozzle or outlet of the extinguisher has a normally leak-tight, but releasable, communicative engagement. The

" invention further consists in the parts and combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawing illustratinga ractical embodiment of'the invention,-

igure 1 is a view inside elevation, showing the extinguisher in place on the supporting bracket;

Fig. 2 is a viewin front elevation, of the bracket with the extinguisher removed, the pipe coupling being shown in section;

ig. 3 is a top p Fig. 4 is a fragmentary view of the discharge end portion of the extin 'sher; and

Fig. 5 is a view illustrating t e invention as ap lied to an aeroplane or automobile.

Re erring now to the drawing, the numeral 1 designates the body shellor barrel an view-of the bracket;

of an ordinary hand fire extinguisher whose end portions 2 and 3 are respectively convexed or crowned.

At the discharge end of the extinguisher is a nipple or nozzle 4, while at the opposite end is the usual operating handle 5, the stem 6 of which latter extends into the barrel 1' and carries or controls the, discharge valve and other internal parts or devices (not shown) for the control and operation of the extinguisher.

'The particular construction and operation of the extinguisher, of itself, constitutes no part of the present invention, except in the general combination and arrangement as hereinafter set forth and claimed. Hence, no further detailed description thereof is deemed necessary in this specification.

' The present mvention, as hereinbefore pointed out, comprehends ,a novel supporting device or bracket. As shown, it com-- prlses a body. member, preferably an elongated, flat plate or bar 7, which is apertured, as at 8, for the reception of securing screws or bolts, or, obviously, it may be otherwise suitably provided or arranged for attachment to the body of, the vehicle, preferably within the cowl, in convenient reach of the operator.

At one end of the member 7 is a concaveconvex plate or sup ort 9 for the reception of the nozzle end .0 the extinguisher, while at the op osite end of said member 7 is a similar p ate 10 for en aging the handle end of the extinguisher, ut difiering, however, in that the first. mentioned plate is preferabl rigid, while the latter is resilient or yielda 1y supported, but with suflicientstrength to normally hold the extinguisher in place and yet permit it to be readily placed in position and removed, at will,

when occasion requires. However, no set design or structure ma be followed in this as considera le modification is.

body member 7 may have a supplemental spring clip 15 attached thereto intermediate its end portions, as at 16, so/that the'two opposed curved arms of the clip may clamp the barrel 1.

To makeclearancefor the stem 6 operating handle so asto permit free maof the nlpulation thereof while the extinguisher is in place, and also to facilitate the placing of the extinguisher on, and its removal from,

- the bracket, the plate 10 is provided with-a nozzle 4 of the extin diametrical slot 17 extending from 'itsmiddle-to the margin, asfshown more clearly in Figs. 2 and 3. In this waythe extinguisher may be readily placed and removed by tilting it on the plate'9 and moving it so as to spring the plate 10', the stem 6 moving into and out of the slot 17, said plate 10 iplressing on the end of the extinguisher to old the latter in place and moving back to normal position when the'same is removed.

The supporting plate 9 is provided with an axially bored mpple or coupling extension 18, which may be screw-threaded, as shown, or otherwise. provided for the attachment of a coupling 19 on a suitable pipe 20 having a nozzle 21. The plate 9 is further provided with a socket 22 to receive the isher and communicating with the bore 1n the coupling extension 18. Obviously, this socket may be of suitable metal and ground to afford a releasable, but leak-tight, fit with. the nozzle 4, or it may be provided with a gasket or seat of material such as pressed fiber or rubber. V

To holdfthe operating hahdle 5 in normal position and guard against accidental displacement thereof it is preferable toprovide a suitable catch or latching device therefor on. the holder. As shown in the drawings this device comprises a substantially Z-shaped member 23 of suitable spring metal, one arm of which is hinged to the supporting plate 7, as at 24, and the other suitably mounted so as to direct its discharge .upon the carbureter, at which place fires more frequently occur. Itis to be understood, however, that the discharge nozzle may be mounted in or on any other:

part of the vehicle so as to be in the pretrained position at any place where a fire is liable to occur and which is not conveniently accessible to the driver.' By this arrangement, whereby the extinguisher. may be operated without being detached from the supporting bracket, thenozzle 21 at the end of the'conducting pipe 20 is always in position to direct the extinguishing agent to the fire, with successful result, in a place heretofore considered rather inconvenient and inaccessible for the use of a hand extinguisher in the usual way, and this without necessitating the operator leaving his regular controlling position in the car, or at least not compelling him to assume an undulyhazardous position or cause him to lose control of the machine. This is particularly advantageous in the case of an aeroplane in flight, wherein the hazard of fire is great and the extinguisher has been found arm pro ect1ng normally upward and having an aperture 25'to recelve the end-portion of said handle 5' (see Fig. 1). The spring tension of this member 23 need be only slight so that it may hold in place and --yet be readily sprung from engagement,

with said handle member'5 and swung on its pivot 24 out of the way when it is desired to operate the extinguisher. v 4

A practical application of the invention to an aeroplane'or automobile is illustrated in Fig. 5-wherein thenumeral 26 designates the body portion of the vehicle in .the region of the drivers seat. In. this instance the supporting bracket is mounted on the dash practically ineffective when used in the heretofore customary manner, due to the time able modification without departing from the spirit of the invention as defined by the appended claims. Therefore, it is not limited to the specific construction and arrangement shown in the drawing.

-What is claimed is: k

l. A supporting device having means for releasably holding a hand fire extinguisher thereon, a'conducting ipe attached to said device andhaving a discharge nozzle, and

means for efi'ecting' a releasable commimica- .tive connection between the outlet of said extinguisherand said ipe.
