UNITED S TATEE HAND FIRE EXTZNGUISHER.

Application filed February 21, 1924, Serial No. 634,332, and in Austria March 23, 1993.

This invention relates to hand lire extinguishers.

Hand fire extii'iguishers have already been proposed in which the rising pipe in the cover of the container for the liquid is arranged as to be longitudinally displaceahle so that it may be caused to act upon the vcsscl containing the acid.

In these forms ot construction the acid containing vessel is connected with the rising pipe, so that it,together with the rising pipe, may be inserted or removed thrmigh the upper aperture of the container. This arrangement presents the disadvantage that through the frequent removal of the rising pipe, if there is careless handling, a possibility always to be contemplated in the case of such an apparatus, the pipe may be dented and bent and also may become loose at the joint connecting the rising pipe with the acid container, or its perforated containing cylinder or cylindrical strainer.

These disadvantages are obviated in the hand fire extinguisher according to the present invention, by an extension rigidly cornected with the sliding rising pipe, which extension acts as a striking appliance for effecting the fracture of the acid carrying vessel.

The appended drawing shows a vertical section of one form of construction of the invention.

In the drawing 1 indicates the peripheral wall of the liquid container or receptacle which is closed so as to be liquid tight and gas tight, by means of a seamed joint with the bottom 2 and the top 3. The bottom 2 has inserted in it an internally screw threaded sleeve 4 through which the perforated cylinder, or cylindrical strainer 6, for the reception or the glass vessel 5 containing the acid, is inserted into the container, after the 'iertorated cylinder 6 has been closed by the screwed closure 7, the thread of closure 7 engaging the screw-thread in the sleeve 4;. The joint is made gas-tight by means of a lead ring and a packing filler.

The glass vessel 5 is provided with a recess or cavity at its lower end said recess engaging a stud or projection 8 on the screwed closure 7 whereon the glass vessel 5 is suitably supported and its fracture is tacilitated.

The top 3 of the container has inserted in it a stufiing box 9 through which the rising pipe 10 passes to the outside, a tight joint being secured by means of the gland 11 and sleeve nut 12. The upper portion 23 of pipe 10 is mounted'to slide freely thro stoning box and to ates at its upp in a knob adjacent v. inch there is located hort tubular extension or pipe 0 indicates an extension upon pipe 10 situated above the upper end ot the perforated cylinder 6.

The upper end 16 of cylinder (l is provi led with a perforation through which a pin 17 extends, which pin, together with a plate 18 rests on the glass vessel 5.

One or several packing discs 19 are provided to prevent any oscillation of the glass vessel in the perforated cylinder 6. i

A blow delivered upon the knob 13, forces the pipe 10 downwardly whereby the extension 15 strikes the pin 17 and smashes the glass vessel 5 containing the acid. The pipe 10 is provided with a branch pipe 24L connected to it above the extension 15 and this branch pipe is provided with a sieve or strainer 20 in order to prevent the entry of splinters from the glass vessel.

A forked clip 21, on the inside of the container 1, holds the pipe 2% and therefore pipe 10 against turning movement in the stuliing box 9 so that the lower end of the pipe is always placed diametrically opposite to the handle 22, hence at the lowest point or" the apparatus during its manipulation.

The striking pin 17 may be dispensed with it the extension 15 of the rising pipe 10 is so shaped that it can act directly upon the vessel containing the acid.

Claims:

1. A hand [ire extinguisher comprising a liquid receptacle, frangible acid vessel in said liquid receptacle, a. cylinder to said acid. vessel, a plate upon the upper end of the acid vessel, a project-ion on said plate, a perforation in the cylinder for the passage of said projection, a centrally disposed discharge pipe, said pipe being longitudinally movable, and an extension on the pipe adapted when the pipe is forced inwards to contact with the projection on the plate upon the upper end of the acid vessel and cause the vessel to be fractured.

2. A hand tire extinguisher comprising a liquid receptacle, closures at each end of said receptacle, a frangible acid vessel in said liquid receptacle, a cylinder for said acid vessel, 9. plate upon the upper end of the acid vessel, a projection upon said plate,

a perforation in the cylinder for the passage of said projection, a centrally disposed discharge pipe, said pipe being longitudinally movable, an extension on the pipe adapted when the pipe is forced inwards to contact with the projection on the plate upon the upper end of the acid vessel and cause the vessel to be fractured, a stud at the lower end of the cylinder for the acid vessel designed to support said vessel and assist in fracturing same.

3. A hand fire extinguisher comprising a, liquid receptacle, a closure for said receptacle, a stuffing box and gland in said closure, a longitudinally movable escape pipe pas-sing through said stuffing box and gland, a port upon said pipe for discharge of eX- tinguishing liquid, a foot upon said pipe, a branch pipe upon said escape pipe leading to the lower portion of the liquid receptacle,

E1 clip upon the wall of the receptacle engaging said braneh pipe, a closure for the lower end of the liquid receptacle, an opening in said closure, a screwed closure for said opening, a perforated cylinder for an acid vessel upon said closure, a frangible acid vessel in said cylinder, a recess in the bottom of said receptacle, a stud upon the upper surface of the screwed closure upon which the acid vessel rests, a plate at the upper end of the acid vessel, a projection upon said plate, a perforation in the upper end of the cylinder for the acid vessel for the passage of the projection, said projection being disposed beneath the foot upon the escape pipe.

In testimony whereof I have hereunto set my hand the 8th day of February, 19:2
