CONTAINER FOR FIR-E-EXTINGUISI-IING LIQUIDS.

Specification of Letters Patent.

Patented Apr. 11, 1916.

Application filed October is, 1915. Serial No. 56,583.

To all whom it may concern. I

Be it known that I, RANDALL T. VAN VAL- KENBURG, a citizen of the United States, residing at l/Vashington, in the District of Columbia, have invented certain new and useful Improvements in Containers for Fire- Extinguishing Liquids; and I do declare the following to be a full, clear, and exact clescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in containers, and particularlythose adapted for use in connection with fire extinguishing liquids, and has for one object to provide a simply constructed device which is readily refillable. p

A further object is to provide means for preventing the binding of the closure protector on the body of the container. 7

A still further object is to provide a device having a closure protector provided with means for readily breaking the closure.

With the above objects in view, my invention resides in the features of construction which will be hereinafter more particularly described and claimed. I

In the accompanying drawing: Figure 1 represents a side elevation of the container showing the dispensing cup used as a closure protector; Fig. 2 represents a top plan view thereof; Fig. 3 is a central vertical longitudinal section; and Fig. lyis a similar view of the upper end of the container showing the dispensing cup removed and the closure broken.

In the embodiment illustrated," the numeral 1 designates a container having a substantially cylindrical body portion 2 and a tapered upper end 3 connected with said body portion. The upper end of this tapered portion 3 is open and provided with internal screw threads 4. Spaced from the open end is an inwardly extending flange 5 which forms a seat for a readily breakable closure 6 preferably in the form of a plate of glass, a gasket 7 being interposed between the closure 6 and the flange 5 to provide an air-tight connection. A cap member 8 having laterally extending outwardly projecting flanges 9 is used for clamping the closure tightly against its gasket. This cap member 8 is here shown as having an opening 10 in its bottom slightly smaller in diameter than the closure 6, the upright portion of said cap being Screw threaded as shown at 11 for engagement with the screw threads 4. The flange 9 extends aconsiderable distance beyond the open end of the tapered portion 3 and has its outer edge turned downwardly as shown at 12 to provide an increased bearing surface for a purpose to appear. This arrangement of the upright parts permits the glass closure to be readily broken in case of fire in order that the liquid contained within the container may be readily thrown on the fire toextinguish the same.

To protect the glass closure 6 against accidental breakage, I provide a cover member here shown in the form of a dispensing cup 13 which is adapted to fit over the taperedend 3 of the container. The closed end of this cup is preferably flat as shown and projecting therefrom is a spur lt used for breaking the closure 6'. This spur 14 may be of any preferred form, but is here shown as comprising a pair of substantially triangular plates arranged at right angles to each other so that in plan view they appear in the form of a cross. One of these plates 14' is provided with an upright notch 15 which opens through the apex thereof and is adapted to receive therein the upper portions of the other member 14:". This plate 14" has an upright notch 15 opening through its base and is adapted to receive the lower portions of the plate 14 as illus trated in Fig. 3. By providing a spur of this construction having downwardly inclined edges, it is evident that the breaking of the closure 6 will be greatly facilitated.

If the spur happens to strike on the edge of the opening in the cap member, the inclined edges of the same will guide the point of the spur onto the glass closure and cause the sameto be broken. It will also be seen that the depression in the top of the container formed by the closure being spaced from the end thereof, also aids in the general result.

When the dispensing cup 13 is in position on the container the only points of contact between said container and the inner wall of the cup is the downturned edge of the flange 9 and the lower portion of the tapered end 3 adjacent its connection with the main body portion 2. This arrangement permits the cup to be forced tightly on the container, thereby providing an additional air-tight joint, without causing said clip to bind. This allows said cup to be quickly withdrawn from the tapered end 3, when the again use it.

These containers may be constructed of various sizes and on the larger ones, I preferably provide handles, here shown formed of hand loops 16 whose free ends are pivoted in the straps 17 which are soldered or otherwise secured to the exterior of the body portion 2 of the container. I have shown two of these handles, as it is obvious that a better grip can be had than if but a single handle were used. In some cases, I also provide the cup 13 with the handles 18 which are similar in all respects to the first mentioned handles on the container. The construction and method of attaching the handles to the cup and the container permit their being folded back against the same, thus taking up very little room in storing the device.

From the foregoing description of the construction and operation of this device, it is obvious that I have produced an extremely simple fire extinguisher which can be very inexpensively manufactured and yet which will be found to be extremely efficient in operation.

I claim as my invention:

1. In a device of the class described comprising a container, a readily breakable closure therefor, a dispensing cup normally disposed over said closure to protect the same, and a spur on the outer side of said cup for breaking said closure.

2. In a device of the class described comprising a container having a tapered upper end, an inwardly extending flange in the upper end of said casing to provide a seat, a readily breakable closure disposed in said seat, a flanged cap disposed over said closure and threaded into the end of said casing, a dispensing cup normally disposed over said closure to protect the same, and a spur on the outer end of said cup for breaking said closure, said spur being substantially crossshaped in plan view.

3. In a device of the class described comprising a container, a readily breakable closure therefor, a dispensing cup normally disposed over said closure to protect the same, and a spur on the outer side of said cup for breaking said closure, comprising a pair of triangular upright plates adapted to be disposed in a plane at right angles to each other, one of said plates having an upright notch opening through its apex and adapted to receive the upper portion of the other plate, the other plate having a notch opening through its base and adapted to receive tllie lower portion of the first-mentioned ate.

p 4. In a device of the class described, a container having a tapered upper end, a readily breakable closure therefor, laterally extending flanges projecting outwardly around the end of the tapered portion, and a dispensing cup disposed over said closure to protect the same, the inner wall of said cup contacting only with the outer edge of the flanges and with the tapered portion adjacent the junction of the body of the casing, whereby the cup is prevented from binding on the casing.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
