- To all whom, it may concern:

Be it known that I, GEORGE H. N EWELL, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in the Art of Manufacturing Projectiles for Small-Arms; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to jecting through said openings of the jacket;j

and the object of my invention is to provide means whereby such projectiles may be produced cheaply andexpeditiously. I

My invention consists, essentially, in providing a soft-metal blank of suitable dimensions, placing thereon a covering of suitable porous material to form the patch, placing on the outside of said blank and covering and substantially without the plane of said covering a suitable casing of material harder and stronger than the said body to constitute the jacket, and having suitable openings therein to permit the patch to protrude therethrough, and finally placing this structure in a suitable mold or die and compressing the same, whereby the metal of the body is caused to flow outward within the spaces or openings of the jacket, carrying the covering therewith, and the form of said parts is suitably changed by such application of pressure, as hereinafter more fully described,and particularly pointed out in the claims.

Reference being had to the accompanying drawings, Figure 1 represents a blank with the covering and easing assembled and ready for the finalstep in the process of manufacture; Fig. 2, a longitudinal section of the same on the line 2 2 at Fig. 1; Fig. 3, the same after final treatment by pressure and changed in form thereby to constitute the finished projectile; Fig. 4, alongitudinal section of the same on the line 4 4 of Fig. 3;

Fig. 5, an enlarged. detailshowing the man-V ner in which the metal of the blank fiows o'utward through the openings in the casing and around the wire forming the saine when'such wire is used; and the manner in which the covering is carriedbutward through said openings by such flow of the metal, and Figs.

6, 7, 8, and 9 show corresponding views of a modified'construct-ion adapted to the same i A represents the s0ft fh a b0 (1y of the P jectile, which is first formed in any suitable manner in the shape of a substantially cylindrical blank of less diameter and greater length than'the finished projectile is intend- 7 ed to be.

B represents a covering of suitable porous material to constitute the patch, which covering is attached to the blankby any suit--v able means and encircles the same, said cov-.

ering being of sufiiciently-yielding material to change form and permit the flow of the metal constituting the blank without tearing v or parting. v

C is the casing to form the jacket, which in Figs. 1 to 5, inclusive, consists of a suitable wirefwound spirally on the outside of the said patch and with spaces or openings between the turns of the same, except one or more turns at the respective ends of the same,

and in Figs. 6 to 9, inclusive, consists of a shell of thin steel having suitable openings, said casing in each case being substantially outside the plane of the blank and covering when first applied-,as shown in Figs. 1 and 6, and the wire casing having its coils a little more open than in the finished product to permit of the longitudinal compression of the structure by the flow of the metal of the body when under pressure, as hereinafter described. The end of this wire may be secured by inserting the same in the body, as shown, or in any other convenient manner, provided it have suitable openings at intervals through which the patch may be forced or carried by the flow ofthe metal comprising the blank when subjected to pressure, as described.

From theforegoing description the opera- 8 tion of my new art of manufacturing projectiles for small-arms will be readily understood. 7

When the blank A,c0vering B, and the casing O are assembled, as shown in Figs. 1

and 2, and placed in any suitable mold or die of proper dimensions and subjected to pressure by any-suitable means, the structure will assume the form substantially as shown vin Figs. 3,4, 8, and 9, the metal comprising the blank flowing lateral-1y outwardthrough the openings in the casing G, carrying the covering outward through said openings until arrested by the wall of the inclosing mold or die, and thence the metal will flow around the wire when wire isiused, partially inclosing the same and effectively securing thesaid wire in place by embedding'the same in the surface of th projectile, as shown in Fig. 5.

I do not claim herein projectiles construct ed as described herein, the same being made the subject of separate applications, as fol-' lows: patent on projectiles numbered 621,697 and dated March 21, 1899, and also an application for patent filed March 29, 1899, Serial Having thus-fully described my invention, :whatI claim, and desire to secure by Letters Patent, isp 1.: The art of manufacturing projectiles for small-arms consisting of, providing a blank of soft metal and of suitable dimensions, placing thereon a casing having suitable lateral openings, said casing being at first substantially outside the plane of the blank and secured in plac'e thereon, placing said blank andcasing in a suitable mold or die, subjecting the same to pressure whereby the metal blank is caused, to flow laterally through the openings of the casing and is reduced longi tudinally, substantially as described.

2. Theart of manufacturing projectiles for small-arms, consisting of providing a blank of .soft metal of 'substantially-cylindrical form, winding a suitable wire spirally upon the outside of said blank and with open spaces small-arms, consisting of, providinga blank p of soft metal, substantially cylindrical in form and of suitable dimensions, placing thereon a covering of porous and yielding casing of, harder and strongermaterial than I material, placing outside the said covering a that of the body and provided with openings securing thesame in place on the blank, and

finally subjecting said structure to pressure in a suitable mold, whereby the metal of the blank is caused to fiow laterally outward through the openings in the casing, and assume the change of form, substantially as described.

4:. The art of manufacturing projectiles for small-arms,consisting of, providinga blank of soft-metal of substantially-cylindrical form, appl ying thereto a porous and yielding covering,windin g awire outside of said patch and at intervals thereon,and insertingthe ends of the wire in said body, and subjecting said body, covering and wire to longitudinal pressure,

,in a'suitablemold, whereby the metal ofthe blank flows outward between the coils, bring: ing the coils of the wire within the plane of the projecting portions of the covering, and I securing each separate turn of wire in place' within the body of the projectile,substantially as described.
