JULIAN S. GRAVELY, OF WY'IHEVILLE, VIRGINIA, ASSIGNOR TO WINCHESTER BEPEATING ARMS (30., OF NEW HAVEN, CONNECTICUT, A CORPORATION.
PAPER SHOT SHELL.
No Drawing.
T 0 all whom it may concern:
Be it known that I, JULIAN S. GRAVELY, a citizen of the United States, residing at Wytheville, in the county of- Wythe and 5 State of Virginia, have invented a new and useful Improvement in Paper Shot Shells; and I do hereby declare the following tobe a full, clear, and exact description of the same.
My invention relates to an improved paper shot-shell and a tube to be used in the manufacture thereof, the object being to produce a smooth, hard and tough paper shot-shell of superior impermeability to moisture, high resistance to powder-burning and to the passage of hot gases, and a texture which adapts it to hold its crimp under all conditions of handling and climatic changes. A further object of my invention is to produce a superior shot-shell of the character described, without resorting to any operations other than those commonly used at the present time'in the production of par-shell cartridges.
With these ends in view my invention consists in a paper shot-shell having a plurality of superimposed coils of paper adhered by co-extensive interposed coils of adhesive, the said paper containing as one of its ingredients, a percentage of solidified vegetablelatex.
My invention further consists in a paper shot-shell tube for use in making the same as will be hereinafter described and pointed out in the claims.
In carrying out my invention, I employ a specially prepared paper shot-shell paper contaimng a small percentage of inspissated vegetable juice such as the solidified latex of the rubber tree, to which, however, I do not limit myself since a variety of coagulable vegetable juices will meet the requirements of my invention. The percentage of such inspissated juice ingredient will vary according to its character and the character of the other ingredients in the paper, but my present idea is that it will vary between a fraction of one per cent and fiveper cent. Such a paper is wound upon a suitable manof its faces a continuous film of a suitable paste, resulting in a paper shot-shell tube containing an element of inspissated vegetable juice and characterized by a plurality drel after the paper has had applied to one s I Application filed. August 14, 1922. Serial No. 581,896.
of superimposed coils of such paper and coextensive interposed coils of an adhesive film, adhering the respective coils of paper. The moist tube so produced is then dried, sized by passage through appropriate dies, and cut into shot-shell blanks, which are then provided with heads and loadedand crimped in accordance with established practice.
Shot-shells so produced participate in the characteristics of the paper employed in them and exhibit extreme toughness, hardness, smoothness, impermeability to moisture, resistance to powder-burning and the passage of hot gases and hold their crimp better than those of ordinary manufacture, since the employment of a percentage of inspissated vegetable juice so modifies the texture of the paper that it renders it remarkably retentive of crimp. Moreover my improved shot-shells on account of their impermeability to moisture do not change their shape upon exposure thereto, on account of their toughness and hardness are not easily abraded by being carried loose in the pocket, and, generally, maintain their external shape and internal character better than the shot-shells of the prior art.
I do not confine myself as already indicated to the use of paper having introduced into it in its pulp form, a percentage of the inspissated juice of the india rubber tree alone,- as there .are other vegetable juices which exhibit the property of coagulati into a tough, moderately hard and state under the proper treatment. I do not, therefore, limit myself to the use of inspissated rubber tree latex, nor do I limit myself to the use of the coil-method of producing the tubes.
I am aware that paper shot-shell tubes havebeen impregnated by immersion in solutions containing a polymerizable oil which has thereupon been polymerized by heat, forming a solid substancev in the interstices of the paper. This solid is characteristically a resin, relatively brittle and inelastic and does not exhibit the peculiar quality, characteristics and advantages of coagulated latices.
I claim 1. As a new article of manufacture a paper shot-shell consisting of a plurality of superimposed coils of paper adhered by co-exof an adhesive interposed between and unit- 10 in them.
11 testimony whereof, I have signed this specificatlon 1n the presence of two subscribing witnesses.
