CORPORATION or anoint: ISLAND Finn EXTINGUISI-IER Application filed May 9,

This invention relatesto. fire extinguishers of the type in which fire extinguishing fluids are contained. in tightly sealed bottles, that are adapted to be mounted in such a manner that the sealis broken when the normalposition of the bottle is changed.

I An object of the invention isto provide a fire extinguisher wherein the fire extinguishing'fluid is contained in a bottle sealed with a crown cap stopper.

Anotherobject is to provide a fire extinguisher wherein the container for the lire extinguishing fluid is carried by abracket in such a manner that the seal will be broken when the container is being removed from the bracket. 1

' Another object is to produce an eflicient, strong and durable fire extinguisher which may be economically constructed and operated.

With these and other objects in view, the invention consists of certain novel features of construction,-as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings Figure 1 is a perspective view of a fire extinguisher constructed according to my in vention, showing the container in its normal position in the bracket;

Figure 2 is a vertical longitudinal section showing the container being removed from the bracket;

Figure 3 is a detail section of the upper portion of the bracket; 1

Figure 4 is a horizozntal section taken along the line 4- of Figure 3; and

Figure 5 is a view similar toFigure 3 illustrating a modified construction.

It has been found in practice that a simple and inexpensive fire extinguisher is desirable and in order to construct such a device, I have provided means by which any common type of bottle having a crown cap seal stopper maybe used for containing the fire extinguishing fluid. The construction is such that a a tightly sealed bottle is mounted in a. bracket in such a way that the bottle cap will be removed when the bottle is withdrawn from the bracket, and the bottle can not be with 1928.

drawn from the bracket without also causing the removal of the cap.

Referring to the drawings, the device coniprises a bracket 11 in the tormof an elongated body, near theupper end of which are laterally projecting ears 12 provided with openings 13 for receiving suitable fastening means (not shown) for securing the bracket in a vertical position on-a wall, post or other supporting surface.

anarcuate flange 14: constituting a base for supporting a liquid container 15. I The container 15 may be in the form of an ordinary bottle having a head 16 formed at the top of its neck-for receiving the crimped edge 1? of a crown cap stopper 18.

Below the cars 12, the edges of the bracket are notched, as indicated at 19, for receiving the arms 20 of a retaining member for the bottle. 'lhearms 20 are so positioned as to partly encircle the bottle and hold the same adjacent to the bracket, and for this purpose the arms 2O-sl1ould be formed from a strip of suitable resilient material, such as spring steel, or the like, which is riveted to the back of the bracket, as indicated at 21 (Figure 1).

The upper portion of the bracket is extended to provide a horizontal arm 22 adapted to overlie the top of the bottle. Near; its outer end, the arm 22 is provided with a threaded opening 23 for receiving the shank of a vertically disposed screw 24.

lVhen abottle is mounted in the br cket with the base or" the bottle resting on the flange 14 and the arms 20, encircling the bottle the under ,face ofthe arm' 22 should be spaced slightly from the top of the cap 18 and the screw 24 should be positioned slightly in front of the upper portion of the bottle.

, Paralleling the ar1n22, but spaced a suitable distance'therebelow,'is an arm 25 which may be formed integrally with the bracket, as shown, and be reinforced by side pieces 26, also integral with the body of the bracket.

The arm 25 has a. notch 2'? formed in the projecting) edge thereof, which notch is shaped to snugly fit the top of a bottle directly beneath the'cr'imped edge of the cap 18. Therefore, the edge of the notch'is inclined 'l he bottom of the bracket is provided with outwardly from the upper surface thereof, as outwardly from the said body, and means indicated at 28 so as to provide a relatively movably mounted in the said top section for broad surface for engaging the crimped edge preventing accidental displacement of the upof the cap (see Figure 2) and permit indcper portion of the said container. pendent movement of the bottle neck rcla- 2.

FRANK E. DYSON;

When it is desired to insert'a capped bottle in the bracket, or when it is desired to remove a bottle from the bracket Without decapping the same, the screw 24: is turned upwardly a distance sufiicient to clear the top of-the cap 18. This will permit a bottle to pass in or out of the bracket'in a vertical positionI- In some cases it is desirable to provide'aquick acting member in lieu, of the screw 24', such for instance as the form of device shown in Figure 5 wherein, the end ofthe arm 22'is perforated, as indicated at for a pin 31 carried on one end of a leaf spring 32. The other end of the spring'is fixed to the bracket by means of screws or the. like 33." In this form of the invention the spring32 will main-- tain the pin 31 in'a normally depressed position and when a bottle is being inserted in the bracket the pin can be raised under the tension of the spring to permit the passage of the bottle neck. When thebottle has been prop erly positioned in the bracket, the pin can be released and the spring will return the same to itsnormal position.

The foregoing description is directed solely towards the construction illustrated, but I desire it-to. be understood thatI reserve-theprivilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims;

The invention claimed is:-

1. A one-piece bracket for supporting a container provided with a beaded neck can rying a crim-pedcap, comprising a body having a base flange for supporting the said container, a top horizontal section overlying the said cap, means carried by the body and paralleling the said top for engaging the lower edge of the said cap and removing'the same from thecontainer when the latter is swung-
