Specification forming part of Letters Patent .No. 133.066, dated November 12, 1872.

. thereon, to be afull, clear, and exactdescription of the same, and which said drawing constitutes part of this specification and represents, in-

Figure 1, a front view; Fig. 2, a sectional side view; and-in Fig. 3, a vertical longitudinal section on line a; w.

o a I This mvention relates to an improvement a in machines for forming bullets by the process of swaging-that is to say, a machinein which a lead blank is swaged intothe form required for the bullet. In this class of machines it is necessary that there been opening in the-die or follower through which the surplus lead may escape; but this necessitates the trimmin g of such surplus lead from the bullet after it is formed; The object of this invention a primarily is to allow for this escape audhtrim the surplus lead from the bullet while in the die; and it consists in forming a vertical perforation in the follower eccentric to the center, into which perforation the surplus lead will pass, and after the follower hasperformcd the work of compression, a partial rotary movement is imparted thereto, which causes the follower to turn upon the end of the bullet, and the perforation, which is eccentric to the axis of the follower, turns out of position where the surplus entered and cuts from the bullet the surplus which it contains, thus allowing the bullet to be dischargedlfrom the machine complete and perfect. My invention also consists in the mechanism hereinafter de-. scribed for supplying the blanks for the oper-;

ation of the follower.

A is the bed of the machine, within which,

at .a, are. arranged the usual dies for form-- in g the bullet. i Above this, in suitablebearings B B, is arranged the follower G, and to which a vertical movement is imparted from the driving-shaft 0 through a crank and 1ever, 0 or otherwise, so that a blankbeingplaced in the die and the follower fordedthereon will compress the bullet in the usual manner. In the lower end of this follower I form a vertical perforation, or opening, d, (see Figs. 2 and 2%) this perforation being eccentric to the axis of the spindle, and opening out at some point above, as denoted in Fig. 2. To this follower at the proper time, as hereinafter described, a rotating movement is imparted by means of a cam, D, actuating a slide, D, (see Figs. 2 and 2**;) the said slide in moving back and forth being in connection with the follower causes it to rotate accordingly. As the follower strikes the lead blank and compresses it the lead, more than is required for the bullet, will be forced up through the perforation d in the follower until a bullet. is

completely formed, then the before-mentioned rotary movement is given to the-follower, causing it to turn upon the end of the bullet, and as the perforation'd is eccentric to the axis of the follower this perforation is car-- ried off from this point on the bullet, and in so doing cuts the surplus which is in the perforation smooth and clean from the bullet,

then the ball is discharged in the usual mam ner. Thus the bullet is completed, and comes from the machine requiring no furtheroperation. v

To automatically supplythe blanksfor the action of the follower, a slide, L, 'is arranged longitudinally on the machine in suitable guides, and actuated by suitable mechanism to impart a longitudinal movement thereto, here represented as from acrank-wheel, N, the said slide fitted with an opening, b, as seen in Fig. 3, to receive the blank in one position, and by its longitudinal movement to carry this blank beneath the follower to deliver the blank to the die. With this slideis combined a vertical tube, P, denoted in solid black, Fig. 3, this tube extending to near the mouth of a hopper, it. Over this is a sleeve, S, arranged rto slide freely on the tube P, and is in connection, by an arm, T, with the follower, so that as the follower-rises and falls this sleeve rises and falls with it. The upper end of the tube 1? is formed or cut at an angle, as seen in Fig.

3, leaving no point upon which a blank may rest. The sleeves passing up and down over the end of this tube, as denoted in broken l1nes,F1gs. 2 and 3, constantly agitates the mass of blanks in the hopper around the end 'of the tube, thus causing the blanks to follow each other successively into the tube P. This tube P stands directly over the opening b in the slide L, so that when the opening comes beneath the tube it takes a blank therefrom and transfers it to the die, then returns for a second, and so on. I

I have represented the follower as having a reciprocating and. rotating movement with stationary dies but it will be evident to those familiar with machinery of thischaracter that the same result will be attained by a station ary follower and reciprocating and rotating die, or these movements may be imparted to one or the other, or both.

I claim as my invention .1. In a machine for swaging bullets, consisting of the follower C and the usual die, one or either or both having a reciprocating movcment, the perforation d in the follower, combined with mechanism 'to rotate the said follower, substantially as and for the purpose set forth.

2; In combination with a follower and die for swaging bullets, I claim the tube Pjan'd reciprocating sleeve S and slide or carrier L, substantially as and for the purpose set forth.
