SPECIFICATION forming part of Letters Patent No. 481,731, dated August 30, 1892.

Application filed September '7, 1891I Serial No. 404.940. (No model.)

To all whom, it may concern.-

Be it known that I, JOHN F. MOGRAIL, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Machines for Swaging and Creasing Bullets; andI do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, which said drawings constitute part of this specification, and represent, in-- Figure 1,a front view of so much of the swaging-machine as is necessary to illustrate the invention; Fig. 2, a plan view of the swaging-machine in partial horizontal section and of the creaser, showing so much of each machine as necessary to the understanding of the invention and also showing the conductor and its mechanism for delivering the swaged bullets from the swagingmachine to the creaser; Fig. 3, a vertical central section through the swaging-die, through the blankdelivering slide, and through the receiving slide and tube, showing the receiving-tubein its normal position; Fig. 4, the receiving-tube as arranged to receive a bullet from the swaging-die; Fig. 5, a vertical section of a portion of the creaser and the end of the delivering-tube at the creaser, illustrating the manner of successively delivering the bullets to the creaser.

This invention relates to an improvement in machinery for the manufacture of bullets.

In the usual method of manufacturing bullets a machine is employed which is adapted to receive the lead blanks and present them to the dies to be swaged into shape. The swaged blank has heretofore been taken from the machine and delivered by hand to the creasing-machine, thus necessitating the presence of an attendant between the two machines to properly deliver the swaged blanks to the creaser.

The object of my invention is to combine with the two machines a device for automatically transferring the swaged blanks to the creaser, and in such a device, as more fully hereinafter described,and particularlyrecited in the claim, my invention consists.

A represents the bed of the bullet-swaging machine, in which, between vertical guides B B, the gate or slide C is arranged to recipro cate, such reciprocation beingimparted to the slide from an eccentric on the driving-shaft D, the slide carrying the swaging-punch E, and the die F, arranged in the bed below, the die being of a shape corresponding to the outer surface of the bullet and so' that, the lead blank having been introduced into the die, the slide C descends, bringing the punch E upon the blank, so as to swage it into the required shape.

Beneath the die and in line therewith is a vertically-reciprocating follower G, the upper end of which in operation forms the bottom of the die, as seen in Fig. 3, so that after the bullet has been swaged and the punch E withdrawn the follower G rises and forces the swaged bullet up out of, the die and then returns, preparatory to receiving the second blank.

H represents a slide arranged to reciprocate in a path at right angles to the path of the punch E and so as to be moved inward over the die F, as indicated in broken lines, Fig. 3, or withdrawn therefrom to its normal position, as shown in that figure. Reciprocating movement is imparted to the slide H by means of a cam I through a lever J. (See Fig. 2.)

A conductor K leads to the slide H when in its normal position, as seen in Fig. 3, and through which the blanks are conducted to the slide, so that one,'as L, will fall therein when the slide H stands beneath the conductor, as represented in Fig. 3, and which blank upon the next advance of the slide H will be presented over the die F, so that the blank L may drop into that die, the slide returning before the punch E descends. The punch E having operated upon the blank the follower G rises and forces the swaged bullet from the die, as before described. So far the machine is a common and'wellknown construction. The bullets thus swaged require that the annular creases shall be formed therein, and this is done upon a separate machine, that machine being represented in Fig. 2, M representing the disk arranged to revolve in a horizontal plane, between which and the segment N the bullets are pre sented, the edge of the disk and segment having annular ribs thereon adapted to impress the creases into the bullets. Below the disk M is a revolving table 0, upon which the bullets are set with their base downward,and which serves to carry the bullets into the space between the disk M and the segment N. This machine is too well known to require detailed description. As before stated, the bullets have been taken from the swagingmachine by hand and set with their base downward upon the creaser, so as to be operated upon thereby. To avoid this hand labor and make the transfer automatic, the swaging-machine is provided with a slide or, arranged to reciprocate in a path at right angles to the path of the punch E and similar to the slide I-I, so that the slide a maybe moved in over the die F, as seen in Fig. 4, or withdrawn therefrom, as seen in Fig. 3, which shows the slide in its normal position. The reciprocating movement is imparted to the slide a by means of a cam Z) on the shaft cl, being the same shaft as that upon which the cam I is arranged, this cam operating upon a lever e to take the slide into a position over the die, as seen in Fig. 4c. A springf is pro vided to return the slide to the position seen in Fig. 3. The time for the presentation of the slide a over the die is after the punch E has risen from the swaging operation and before the follower G rises. Hence when the follower G rises it will force the bullet which has been swaged up into the slide a, as represented in Fig. l. Then the slide 0tv returns it to its n0rmal position, as seen in Fig. 3. From the upper side of the slide a a tube g leads to the creaser as a conductor for the bullets. lhis tubeis flexible suflicient to permit the movement of the slide without deranging the tube as a conductor. There will therefore be a column of bullets within the tube, each successive swaged bullet raised therein pressing the column upward and forward through the tube 9 to the extent of the last bullet introduced. The tube or conductor 9 leads to the creaser, as seen in Fig. 2, so as to conduct the swaged bullets to the creaser. At the creaser and in order to bring the bullets into proper position thereon the tube 9 opens horizontally, as seen in Fig. 5, and is supported on a bracket on the creaser, the bracket having a horizontal opening 7L, corresponding to the tube, and over the disk 0 is a like opening 11, in line with the opening it from the tube, (see Fig. 5,) so that a bullet discharged from the tube 9 through the opening 71. will drop with its base downward through the opening a onto the disk 0, r

as represented in Fig. 5, from whence it will be carried between the creasing disk and segment. As each successive bullet is introduced into the tube 9, a bullet at the other end of the column will be discharged into the creaser, and thus, the swaging operation being continuous the supply to the creasingmachine will be equally so, and this without the interposition of hand labor between the two machines, practically combining the two machines as one automatic machine. To engage the bullet which is introduced into the slide a, so as to prevent its return into the die as the follower Gr descends, a spring-latch Z is arranged upon the under side of the slide a, which will yield as the bullet rises and return when the bullet is completely raised, so as to hold the column of bullets against return movement, the nose of the latch being beveled upon the under side, so that the rising bullet will readily force the latch out of the path of the bullet, the spring of the latch permitting it to return as soon as the smaller portion or point of the bullet shall have passed above the latch. In case the follower G is arranged to stand in its up position flush with the surface on which the slide a moves and so that the slide a may take the bullet directly from the end of the follower onto the surface beneath the slide the latch Z may be dispensed with.

I claim- In an apparatus for swaging and creasing bullets, the combination of the swaging die and punch, a reciprocating follower adapted to work up and down through the die, a slide arranged to reciprocate in a path at right angles to the path of the punch and between the punch and die, the slide having an opening through it of a diameter corresponding substantially to the diameter of the swaged bullet and so that when the said slide is pre sented over the die the upward movement of the follower in the die will force a swaged bullet from the die into said slide, a tube leading from the upper side of said slide and terminating at an opening to the creaser, substantially as described, whereby the swaged bullets delivered from the die through said slide form a column in the tube, which aut0- matieally conducts and delivers the said bullets successively to the creaser.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

JOHN F. MCGRAIL.
