PARKER RICHARDSON BRADLEY, OF EAST ORANGE, NEW JERSEY,=ASSIGNOR TO AIR- CRAFT FIREPROOFING CORPORATION, O1? .NUTL'EY, 'NEW JERSEY, A CORPORA- TION OF DELAWARE.
POWDER-BAG;
Application led March'22, 1918. .Serial No. 224,075.
To all whom t may concern: y
Be it known that I, PARKER R. BRADLEY, a citizen of the United States, and a resident of East Orange, in the county of Essex and State of New Jersey, have invented a new and Improved Powder-Bag, of which thev following is a full, clear, and exact description. v
This invention relates to powder bags for use for the explosive charge for cannon or large guns.
At the present timepowder bags are made l of silk or equivalent mat-erial which willy not blaze, flame or vspark when fired fr om the cannon, but the disadvantage of this kind of bag is that the material is expensive and tho supplylimited. v I
rThe object of the present inventlon is to provide a substitute for. silk powder bags,
which will not blaze, Hame or spark and yet which will permit of rapid ignition of the charge from the flame of the primer, explosive cap or other ignition means, the substitute bag being of comparatively cheap fiber, such as cotton, jute, fiax, linen or the like, which can be had in unlimited quantity in this country and can also be fabricated here.
The cotton yarn or cloth or other cheap liber is rendered fireproof by ammonium phosphate solution or the equivalent, and according to one method the bag is made of this reproof material throughout its entire structure.
For a more complete understanding of the invention reference is to be had to the following description and claims taken in connection with the accompanying drawing, which illustrates certain embodiments of the invention and wherein similar characters of reference indicate corresponding parts in allV the views.
Figure l is a perspective view of a powder baO;
Fig, 2 is a longitudinal section thereof;
Fig. 3 is a similar view showing the ignition end of the bag of an open weave; and
Fig. l is a perspective view of a cartridge, of smokeless powder drawn on a considerably reduced scale compared with Fig. l.
Referring to the drawing, l designates the body and 2 and 3 the ends of the powder bag which contains a charge of powder 4. The
body'of the bag is made of cotton cloth which is fireproofed in any suitable manner and with any suitable material so as to prevent the fibers from burning and becoming a menace inA a powder magazine, turret or other place where an explosion might occur from a flaming bag. The bag or cartridge casing may be constructed 4wholly of cotton or other cheap cloth with an open mesh weave, or the bag may be constructed of cot-` as Shown in Fig. 4, not only the ignition end.
7 maybe made of silk, silk and cotton, or open weave cotton cloth`v but the walls 8 of the flame channel 9 are also made of the same material, so as to permit the flame from the black powder bag in the gun charge to effectively ignite the entire mass of smokeless powder of the cartridge.
While I prefer to flreproof a woven fabric rather than a yarn, mainly on the ground that a fabric is more easily handled than a yarn, nevertheless, a yarn may be ireproofed and afterward woven into an open mesh fabric which will not require further fireproong. In fireproo-fingl the yarn or cotton,
or other fabric, a bath is prepared containing a very small portion of ammonium phosphate or other fireproofing materials dissolved in a very large proportion of water yielding a liquid practically as fluid water. The bath is then gently heated and the yarn or the cotton or other cloth is then passed through this bath where it may pass between various rollers which will force the liquid into the innermost recesses of the fiber of the cloth or yarn. As an additional means of impregnating the cloth or yarn, the cloth or yarn w-hen it emerges from the bath may be wound up in large rolls or reels and allowed to stand for a considerable time, so that through capillary attraction or otherwise, every innermost particle of the fiber composing the cloth or yarn may become impregnated with the fireproof solution. The cloth may be dried in any well known manner and may be redried and retreated as often as may be desired, but always with great care tha-t the mesh or' the cloth be left open.
From the foregoing description taken in connection with the accompanyingdrawing, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while I have described the principle of operation, together with the article which I now consider to be the best embodiment thereoi;T desire to' have it understood that the article shown is merely ilhistrative and that such changes may be made when desired as fall within the scope of the appended claims. Y
Having thus described my invention, l claim as new and desire to secure by Letters Patent:
l. A powder bag or cartridge casing which permits the normal passage of hea-t waves, the bag or cartridge casing being` wholly ireproofed.
2. A powder bag or cartridge casing,` 'having its body portion formed 0f a woven fabric ii'npregnatcd to render the saine fireproof, the woven fabric having` openings in its mesh to prevent interference with the ignition of .the explosive charge contained in the bag or casing.
3. A powder bag or cartridge casing having its body portion formed of loosely woven fabric to provide an open mesh and impregnated to render the same ireproof.
4L. A powder bag or cartridge casing having its body portion .formed of loosely woven fabric of open mesh, said :ta-bric beingtreated to render same reproof and without closing` said open mesh.
5. A powder bag or cartridge casing having its body formed of a ireproofed fabric with ay portion having an open mesh to prevent interference with the ignition of the explosive charge contained in the ba g or casing.V 1
6; A powder bag or cartridge casing having its body formed oi' a lireproo'f material with a portion having openings to prevent interference with the .ignition of the cxplosive charge contained in the bag or Casin 7 A powder bag or cartridge casing having' its body formed of a ireproof fabric with a wall for a. flame channel, the wall havinoa openings there-in.
8. powder bag or cartridge casing having its body formed of a tireproo'li 'fabric with a wall for a flame channel, the woven fabric at the flame channel having an open mesh, for the purpose specified.
