HTTK

Patented Feb. 22, 1944 UNITED STATES PATENTV 2 Claims.

The present invention relates to incendiary bombs and has for its main object the provision of a receptacle of frangible material, which on impact with the target may break and shatter to release the inflammable fluid contents, which in turn may be ignited by firing means carried externally by the receptacle.

Another object of the present invention is the utilization of an ordinary glass bottle for a receptacle adapted to be filled with inflammable iluid and which upon impact at the target may spill when the receptacle is broken or shattered and may be ignited by ignition means carried externaily by the receptacle.

A still further object of the present invention is the provision of an incendiary-bomb of the type hereinabove indicated, and which may be provided with means for facilitating shattering of the receptacle when the same strikes the target and with means for directing the fall of the bomb with the mouth of the bottle disposed downwardly, when a bottle is used, in case the bomb is thrown form an aeroplane, or for directing the mouth of the bottle forwardly when the same is manually thrown and the bomb travels on a horizontal line.

A still further object of the present invention is the provision of an incendiary-bomb of the type indicated, and having a bottle filled with inflammablefluid, and which on striking target would shatter and release the inflammable fluid, the latter to be ignited, with means therein provided to direct the travel of the bomb with the mouth of the bottle disposed into the direction of travel.

With the above general objects in view and others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.

In the drawing forming a part of this application, and in which like designating characters refer to correspondingparts throughout the several views;

Fig. 1 is a longitudinal cross-sectional `view through the bomb;

Fig. 2 is a transverse cross-sectional view on line 2--2 of Fig. 1;

Fig. 3 is an enlarged transverse cross-sectional view online 3-3 of Fig. 1;

Fig. 4 is an enlarged transverse cross-sectional view on line 4-4 of Fig. 1; and

Fig.5 is an enlarged cross-sectional view on line 5-5 of Fig. 1.

Referring to the present drawing in detail there is shown therein a glass bottle I0 having a mouth II. Bottle I0 is enclosed within canvas casing I2, extending substantially to the neck of the bottle, for the purpose hereinafter stated. Said canvas casing I2 snugly ts the outline of the bottle. Extending from the central body portion of bottle I0 and substantially to the neck portion thereof, is a comparatively thick cover I3 made of cotton or any other suitable absorbent and readily inflammable material. Adjacent both ends of said cover I3, the same is tightly wound by wire strands I4 to maintain said cover I3 in a snug operative position with respect to bottle I0 and canvas casing I2.

A pair of clamping members I5 are positioned around the neck of bottle I0 and rigidly main tained thereon by means of a pair of screws I6. Said clamping members I5 carry an ignition casing I1 adapted to receive a supply of inflammable material such as .benzine or like inflammable fiuid. Said casing I1 carries wick I8 and a flint striking wheel I9, which frictionally contacting with the upper end of flint stone 20 is capable of producting a spark to ignite wick I8 which is saturated with inflammable fluid within casing I1. Said casing I1, wick I8, ilint striking wheel I9, and flint stone 20, constitute means for igniting cover I3, as will be hereinafter described, and correspond to the elements found in ordinary cigarette lighters.

Bottle I0 is adapted to receive a supply of inflammable fluid 2|, such as gasoline or benzine, which however does not completely fill out bottle I0, .but leaves a comparatively small air space as at 22.

When bottle I0 is llled with inammable fluid 2|, it is sealed by stopper 23, which may be made of cork, rubber or any other suitable material, to be receivable within mouth II of the bottle. Passing longitudinally of said stopper 23 and in an axial relation therewith is the narrower end of a club-like member 2l which has a plurality of outwardly flaring walls 25 eiectlng a plurality of angular edges 26. The narrower end of said club-like member 24 terminates in a screw 21 which passes beyond the inner end of stopper 23 said club-like member 24 disposed into the direction of the fall, in order that said club-like member 24 may rst strike the target. At the impact said member 24 is forced, by its inner end. into the bottle, forcing stopper 22 also into the bottle until edges 28 come in contact with the mouth of the bottle. The air pocket 22 facilitates compression of the contents of bottle I and thereby permits shifting of said member 24 into the bottle. Sharp edges 28 cutting into the mouth of the bottle shatter or break the latter so as to spill the contents of the bottle.

spill and will be absorbed by the burning cover I3,

as the latter of course will not be fully consumed during the flight of the bomb.

At the impact of member 24 with the target, the force of member 24 driven into bottle I0 will not only break the mouth or neck portions of the bottle but will be capable of shattering the body portion of the bottle. To prevent spilling of fluid 2| beyond the immediate vicinity of cover I3, canvas casing I2 connes fluid 2|. Since casing I2 is made of canvas, it will become also saturated with inilammable fluid 2| when the body portion of bottle I0 is shattered and will itself be ignited by the llame of burning cover I3, thus adding to the efliciency of the bomb.

While there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changesvmay be made therein without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

1. An incendiary bomb comprising a receptacle of frangible material, a quantity of inflammable material therewithin, a casing of fibrous material enveloping said receptacle, a wedding cover enveloping said casing, said receptacle being adapted to be shattered on striking a target for releasing said inflammable material, the released inflammable material being adapted to saturate said wadding cover and said casing and to be substantially retained within the confines of the latter, and means carried by said receptacle for igniting said wadding cover prior to the release of said inflammable material and said casing when the same is saturated by the released inflammable material fromA said receptacle when the latter is shattered.

2. An incendiary bomb comprising a ask of frangible material, said flask including a constricted end defining a mouth, a quantity of inammable material within said flask, a stopper receivable within said mouth for normally sealing said flask, a weight carried by said stopper, said weight being of an oblong formation and of substantially polygonal shape on cross-section, said weight being adapted to be driven into the mouth of the flask and by its edges to cut thereinto for the purpose of shattering the flask when said weight contacts with the target, and means for igniting said inflammable material when said flask is shattered on hitting the target.
