j The present invention relates to squ1rt guns, and aims'toprovide a novel and 1mconveniently used for discharging a'stream of liquid or semi-l1qu1d fire `extinguishing compound to a fire.

I It i's'the primary object of the invention to provide a squirtl gun, intended especially for use as a fire extinguisher although useful for other purposes also, which may be economically manufactured and sold` which may be conveniently.l and eiliciently used when called into use such as when a fireoccurs or other einergency'` arises, and'which may be thrownaway or discarded after use, so as to avoidlrechargingand trouble incident thereto,'such as required by permanent refillable fire extinguishers and similar squirt f ivhlchthe tube sealing'clip and operating guns. f. Another-objectof the invention' is lthe provision of such a device comprising a flexible tube for holding the liquid and having'a discharge orifice atone end with a quickly-re-v movable closure for saidorifice, and having a key at its other end for conveniently rolling or winding up the tube so as to collapse same. and force the liquid through the orifice under comparatively7 high pressure. A Vfurther` object is the provision of a with a holderto support the device from a wall, dash stored or tra sported with the parts thereof assembled. s that no assembling is necessary -by the purchaser or user,.and the device may be left in the package until t-he necessity arises for its use, or may be lremoved so as ,to be ready for use instantly. I

The invention also includes novel features of construction and assembly to enhance the utility and efficiency of theldevice.

'With .the ore'going'and other objects in viewyvvhich will be apparaent as the description proceeds, the invention resides in the construction .and arrangement of parts, as

' hereinafter described and claimed, it being ing from the spirit of the invention.

In carrying out theinvention, there is i 1 employed a tube 14 of c onvenlent length and size, forexample, to holdv a pint or quart of liquid, and such tube constitutes the Zcasing j f or container for the liquid. The tube 14 vis f metal, alloy or other 1n`aterial5 in order that it may becompres'sedl and' Wound or rolledV up Afor discharging the contents.

The tube -14' has a conical shoulderv'l atl one end from whichy the neck 16 extends that hasa small 6oriiic'e'or aperture :'17 through which the liquid vis dischargedl in a small'.

stream, and .said oriice may be of any suitable size. The orifice is normally closed by a sc reiv cap 18 threadedl on the neck 16 and having a gasket .or packing disk 19 therein t0 prevent leakage. The cap 18 has a needle 20 therein projecting through the orlice 17 in order to prevent said orifice from' being clogged up, and when'the cap. is unscrewed the needle 2O lbeing Withdrawn from the orif fice 17 will leave said oifice open 1n order to .avoid any possibility of said orificembeing plugged up when the device is used. The cap 18 has an outstanding flange 21 for conveniently unscrewing the cap, to facilitate l. metal or material of the tube is provided with reentrantfolds 22 at the opposite edges interfere -with then operation. lfy Ifor any of the taperedV portion, in order thatA the width of the tapered end portion will be substantially the diameter of the tube, as seen in Fig 1n This facilitates packaging the device, as well as being convenient in use. The rear end of the tube (that end which has the orifice 17 being the forward end) is sealed'in any suitable manner, such as by lead burning, brazing, soldering, or the like. It is also possible to coat the inner surfaces with shellac or other adhesive material before the rea-r end of the tubecis compressed, so as to securely seal the tube. The end of the tube may also be compressed in any su1t-` able manner to make the seal thoroughly effective. It is 'preferable to clamp a doubled sheet metal clip 23 over the iattened end of .the tube in order to. complete the seal and resist the breaking of Ithe seal even lthough the tube 14 is subjected to unusual str ain or pressure, such as the accidental stepplng of a person on. the tube when Qn the floor, it being desirable that the tube 14l be capable of withstanding comparatively, high pressures without bursting.

A key is permanently assembled with the rear terminal ofthe tube so as to be ready for use instantly, without. requiring theA assembly of the key with the tube, such as might be confusing, when the device is broughtinto use.`- is shown. the key 24 1s composed of wire and has the T-head or handle 25 and a. loop 26 at right angles to the head.I The loop 26 embraces thefiattened ,terminal of the tube, and is either slipped on, the tube before the clipI 23 is ap^ plied, or is compressed aftermovement over the clip, so that the clip retains. the key on `the tube. The loop ,26' may also be comA 'so as to assist in seahng` the tube. M i

pressed on the tube When the squirt gun, as above described,- is called into use, itis only necessary to unscrew the fcap 18, and-the forward portion of the tube is held in one hand while the other hand isused for t'urningfthe key 24, as seen in Fig. This will wind (gir-roll up the tube around the loopA 26 of the key. so as to collapse theftube, and the liquid therein is forced`through the .aperture 17 at a coin-I paratively-high pressure. lThe stream disf` charging through the orifice 17 may be directed for a considerable distance, so that the liquid maybe directed to flames without having tol approach too closely to the fire.

The folds 22 will travel forwardly along the` tube as the tube is wound up. as seen in Fig. 6, therebyv facilitating the discharge of the liquid, although. in some cases. whenl the pressure of-the liquid is high, thefolds 22 only travel forwardly a short distance of l the' tube before the-,pressure forces the folds outwardly in advance of the wound or 'blled portion of the tube. This, however, does not .supplied atsubstantially the cost of recharging an ordinary refillable fire extinguisher. This has theadvanta ge of the user being able to purchase an entirely new filled squirtgun or fire extinguisher at substantially the lsameqcost asrequired for refilling or recharging an ordinary squirt gun or lire extinguisher. This, even at slightly greater co'st, eliminates the trouble of purchasing a new charge and refilling or recharging, inasmuch as the present device may be sold comparatively cheap andready for'use.

As shown `in Figs. 1-5 a holder .isassembled with the device to support the device vfor convenient access. The holder comprises a board or plate 27 of sheet metal, wood, or other suitable material, having spring clasps 28 secured thereto to embrace the tube 14, thereby holding said tube assembled with the plate 27. The plate 27 may be of -about the same length and width asthe tube, and

ported for convenient access and quick reynioval from the clasps 28, with the key 24 accessible for instant use.

Figs. 1-4 illustratethe device as'it is storedor shipped 'in a convenient package.

Thus, a box or container 3() of cardboard 'or othersuitablmmaterialfis provided.l which,

as shown, has the ordinary end closureiiaps 31. The box is of a size as to conveniently receive the tube 14, and the box is wider in f one lateral dimension than in the other, as seen in Figs. 2 andy 3, so as to accommodate the key 24. The key 24 is arrangedl with its head 25 disposed transversely so as to bear against the corresponding wall of theA 'Y box, as seen in Figs. 1 and 2, thereby spacing the tube from said' wall, and preventing the tube from moving about lloosely'in `the box.-

spaced from the same wall 'by means of'a spacer 32 of cardboard or other suitable maferial," which is disposed between. thel tube 1,4'and thewall of thebdx againstrwhichl the head 25 of the keyxbears.. This provides a convenient package for storing or shipping the device, ,with the device completelygg The spacer 32 hasthe 1.153 The forward end'portion of the tube is also e and having a notch 34- receiving the neck 16 and cap 18. This assists in holding the parts assembled, and when the tube 14 is removed from the box, the spacer 32 will drop from .the tube. Thus, the device may be left in the package until used, or may be removed to be supported by the holder, or

the device when removed may be laid on a shelf or elsewhere.

Figs. 7 and 9 illustrate the rear end of the tube 14a flattened Without the reentrant folds as shown in Figs. l, 2 and 5. A modied form ofgkey is also shown which combines the key and sealing clip, samebeing composed of asingle( blank of sheet metalas seen in Fig. 8.
