APPLICATION FILED JUNI-I 25, 1906.

Patented Sept. 29, 1908.

HENRY LfCARPENTER, QF MINNEAPOLIS, MINNESOTA.

FIRE-EXTINGUISHER.

To all whom tt muy concern:

Be it known that I, HENRY L. CARrnNTER,

ofMinneapolis, county of Hennepin, State of Minnesota, have invented' certain new and useful Improvementsfin Fire-Extinguishers,

. of which the following is a specification.

My invention relates to fire extin uishers ofthe portable type and thee-object o the invention is to improve the devices illustrated 'and described in Letters Patent of the United States, issued to William W. Sykes on the 4th day of April, 1905, No. 786,779, yand to me on the 29th day of August, 1905, No.

A further object is to provide a iire eX- tinguisher which will be more 'simple and practicable to manufacture and more certain of successful operation when used.

A further object is to provide a means for .closing the mouth of a fire extinguishing device whieh can also be applied to a non-rellable bottle.

Other objectsA of the invention will appear from the following detailed descri tion.

The invention consists general y in the various constructions and combinations all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification; Figure 1 lis a longitudinal sectional view of a iire extinguisher embodying my invention.,v Fig. 2 is a sectional view on the line x-x of Fig.- 1. Y Fig. 3

is a detail view illustrating the base orlower ortion and the handle of the receptacle. iig. 4 is a detail view ofthe up er portion of the receptacle showing a sliglflitly modified construction.

In the drawing, 2 represents a receptacle preferably conical in forni, made of metal,

aving a bottom 3 and a handle 4 for con-- venience in lifting the extinguisher and holding it at arms length. The `reeeptacleis preferably made of metal to avoid breakage so far as possible and also for convenience of manufacture and the conical body portion terminates in ,a cylindrical neck 5 having an inwardly turned flange 6 at its upper edge. A metallic ring or bushing 7 iitssnugly within this neck and is interiorly threaded to receive an'exteiiorly threaded plug 8 having a flange 9 which engages the top of the receiptaele and limits inward movement of t e plug. The inner' edge of the bushing 7 has a recess 10 wherein a ratchet spring 11 is fixed and the inner end of the plug 8 has a series Specification of Letters Patent. Application filed June 25, 1906.' Serial No. 323,282.

'by the said springv 'Patented sept. 2e, ieee.

of ratchet teeth thereon which are engaged The ratchet teeth slip past the spring when the plug is screwed into thebushing and preveiit the plug from being unscrewed or removed from the neck when it is once in place thereinY [The neck 12, preferably'of glass has a threaded inner end to fit t-he threads of the plug 8 and a `[lange 13 to bear on the inner end of the plug when the parts are assembled. A pin 14 is inserted into a socket in the innei' end of the plug 8 and this projects into a recess 13 in the flange 13, thereby preventing the neck from being rotated independently of the plug. ln assembling the parte the glass neck will be iirst inserted tl'irough the lug 8 and the latter secured into the bushing and wlienit is seated therein will be prevented from turning-by the ratchet device heretofore described.

The neck-12 is provided with a weakened area formed by an annular groove 14 provided in the outer surface of the neck .near the point where it enters the plug 8. A stopneck 12 and is provided with a tube 16 ex- -tending therethrough and forming communicatingpassage leading through the cork.

The tube 16 has a vflanged outer end a shown and at its inner end is provided with ring metal spider device 17, the edges of whleh lit within anannular recess '1S in the inner end of the neck, thereby eileetually locking the stopper in place and preventing the pressure of the. contents of the receptacle from blow. ing .the stopper out of the neck. A .tube 19 is provided within the i'eceptacle and joined to the inner end of the tube 16 by a flexible connection 20 which allows the 'tube 19 to. drop down and rest upon the wall'of the receptacle so that its .receiving end will always 'be submerged. in the liquid. The tube 19 may be of glass or metal 4as preferred, the

Ilexible oiiit being of some suitable material which will not be affected by the fire extinguishing liquid. The outer end of the tube 16' terminates at a point o )posite the groove 14 and the neck beyond the ltube 16 is iilled with'a suitable plastic material such as kclay iet or concrete 21 which will positively prevent the esca e of pressure from the receptacle and can )e easilyhlled in to the neck when the extinguisher is being charged. ln lace of the concrete or other plastic materia the outer end of the neck may be closed by a suitable cork and sealed in the ordii'i ary way.

4dent that as soon as the nec v From'the foregoing descri tion it is evi- 1s broken off along the line of the groove 14', and this bewill force the-fire extinguishing liquid out upon the pressure in the receptacle.

through the tube and by holding the device and pointing Vthe neck toward the fire a stream of the liquid can be directed thereon from a considerable distance, depending of course,

In some instances it may be desirable to provide a glass instead of a metal receptacle and in that case I prefer to provide a wire shield or covering 22 inclosin the bottle and protecting it from accidenta breakage and also preventing the iiying glass from injuring theersonusing the extinguisher in case the bottle should be too heavily charged.

The size and sha e of the receptacle may of course, be varie and I do not wish to be confined to the particular form illustrated herein.

This invention may be utilized in a non-refillable bottle, the outer end of the neck being closed by any suitable means as a plastic material which will harden when dry, or by glass or any substance which will positively close the neck and prevent access to the inner stopper. The space between the closing means and the inner stopper will be provided but the annular groove forming the weakened area may be omitted, and when it is desired to open a bottle the neck will be cut with a. glass cutter around the lspace between the inner and outer stopper-s and the glass weakened sufficiently to permit the neck to be broken off, then the inner stopper will be removed and access to the contents of the bottle obtained.

When used in a non-refillable bottle the tube extending through the inner sto per will, of course, be omitted and the locking device will be unnecessary,'ex`cept perhaps where the bottle is filled with an effervescent liquid.

The outer end of the neck will be closed by a substance which will harden or set when dry or cold, such as cement or glass, suitable means being provided between the interior of the bottle and the closing means to prevent the means while in a molten or plastic state from flowing down the neck in'to the receptacle. This closing means cannot be dug out, and-to obtain access to thereceptacle it will be necessary to weaken the neck by a glass cutter or other tool soy that a clean break can be made and the liquid poured out.
