A2 in Figs. ,'23 and 3, rapping thmugh the sied aecue forward or backward carrying Vthe movable die toward or from the .stationary die.

To conveniently slide the wedge l0 it is provided on its rear face with a rack 42 which meshes with the teeth on a. segment l5. ll"he segment is pivoted on a' screw pin a6 and beyond the pivot 1s bent or termed into a lever el?. 'lhe movement of the lever shifts the wedge i0 and this operates the movable die. 'i he rack is shown as litting snugly in a recess in the wedge, and holes 43 are provided to enable it to 'oe driven out for repair. 'l'he wedge is provided with a guiding rib i9 extending into a groove in the bed plate parallel with the face of the die, and the movement ot the wedge is liniited by set screws 50 and 31 mounted in bracket arms 52 and of the frame.

As heretoiorestated, the stationary and movable dies carry blades 1i) and 2O respec tively. These blades seat in kerl's in the dies which are of such depth that, in operation, the bottom or innert-ace of the kerf contacts with the edge the blade and the die and blade operate a unit. 'ihe blades are rabbeted at their loi-ward edges, as shown at 60 in Fig. 4, so that they are adapted to engage and mash the upper portion ot' the ribs without contacting with the lower portion. To enable the blades, however, to support the inserted slug when the dies are open, the blades are made slightly movable toward each ,other by means or springs 61,-\vhich are mounted in the respective dies and bear against the outer Vedges of the blades. The movement ot' the blades toward .each other is limited by pins G2 engaging slots in the blades.

B y reason of the spring pressedblades described, when the dies are separated there is provided a space between them suliicient for the convenient insertion of the body portion of the slug. 'l`he blades, however, are always close enough together to extend beneathl the head al ol" the slug and support it. Accordingly, n' hen the blades are separated, the slug may be put in place, and then a movement of the lever -l forces the'movabledie towardthe stationary die, which causes the blades to travel relatively backwardly in their respective dies until seating firmly within the dies, so that, as the knife edges 17 and 1S come practically together to shear oil' the lower portion of the ribs and body, the blade edges above the rabbets have engaged and mashed the upper portion a3v of the slug ribs. Then, on the reverse movement ot the lever 4T, the lower cutoil' portion A2 of the slug is released and drops thm/)ugh the opening 13 in the bed and the upper portion A1 is linished and ready to be removed. A

To insure the slug to be treated being firmly seated in the dies so that theribs will be mashed down immediately adjacent t0 the head of the slug (so that the printing pressure of the finished slug will be taken by the original cast underv surface of the head), I provide a pressing device consisting of al roller on the shaft 71 mounted in roch arms 72 pinned to a rock shaft 73. ligid on this rock shaft is a hand lever Tl. fhen the lever 74 is swung over, the roller is pressed down on the' tace of the slug, which presses the head down iirmly on the

blades

19 and 20. The upper faces of the blades are slightly inclined downwardly, as shown in exaggerated form at G5 in l*"ig.,7, so that sharp edgesare provided onto which the head-ct1 is forced by the roller 70. This line-engagement enables an ordinary hand pressure on the lever Tet to hold the head irmly on the dies so that they act on the ribs immediately adjacent to the head.

To prevent the roller 'i0 injuring the characters cast on the face ot' the slug I make it slightly yielding. For example, it may conveniently be made of hard rubber. The movable die turns the roller slightly with each impression, so that a fresh tace is contina-ally presented and an even wear is insured. A suitable set screw 76 mounted in an ear 77 projecting from lthe lever 74 is adapted to abut the die l5 and form a stop for the downward movement of theroller.

In operating my machine. the slug A, as shown in Fig. 5,'is inserted between the dies by hand or any suitable mechanism. It may be conveniently,shoved in endwise betweenthe dies and dropped. With the slug in this position the operator, with one hand, swings over the lever TLl, holding the slug down on the

blades

19 and 20 and, with the other hand, operates the lever d?, thus cutting'ol' the lower portion ot' the slug and mashing the ribs ras described. Tien, when the two levers are returned to normal position, the bottom portion of the slug drops through the opening 13, as illustrated in F ig. 3.

When the next slug is inserted from the end oi' the space between the dies, it shoves out the finished slug fronrthe opposite end f ot' the machine. Y ,l f

It will be seen that, where onlyia hand 6peration is desired, 'it is, convenient for Vthe operator to stand 'faeingthe edge of the machine shown at the bottom'of Fig. 1; then to insert the fresh slug with the right hand from a convenient supplyand receive the. shoved out linished slug with the lelt hand and place it in a` suitable receptacle; then to shove over the lever 7% with the right hand and pull on the leverl-'T with the 'left hand, completing the treatn'lentof the new slug. Itis to be understood that, if desired, mechanism may be provided for performing these hand operations; that is, mechanism which feeds in the fresh slug 'and removes the finished slug and operates the let ers 'T-i and 47. Y

The combination of a stationary die, a .coacting movable die, a wedge for forcing the movable die toward or from the station-P ary die, a `lever for moving said wedge, a pressing device adapted to engage the face of the slug held between the dies7 and a le-v lever geared with said rack, whereby the operation of the lever may force the movable die toward the other die, said dies being provided with coacting knife edges toshear otl a portion of the slug between them. 23.
