SLUG STACKER.

Application filed April 22, 1921. Serial No. 463,615.

To all whom it may concern Be it known that I, WILLARD E. PRESSLER, a citizen of the United States of America, and resident of Fort Wayne, in the county of Allen and Stateof Indiana, have invented certain new and useful Improvements in Slug Stackers, of which the following is a specification.

This invention relates to improvements in stackers', adapted for use as an attachment on machines for casting printers leads, slugs, etc., and the objectthereof is to provide means for preserving the slugs in an orderly rank upon the table of the casting machine'as they are cut successively from the slug bar so that they may be conveniently.

removed in groups without the necessity of stacking them by hand.

This object of the invention is accomplished by the construction illustrated inthe accompanying drawings in which:

Fig. 1 is a plan View of that portion of a slu castin machine of known t e u on which slugs are cut from a slug bar, the present invention being shown applied thereto;

Fig. 2 is a detail erspective view of the guide including a friction stop arranged thereon;

Fig. 3 is a detail perspective view of a hinge block for the guide bar;

Fig. 4 is a detail perspective view of a slug support;

Fig. 5 is a detail perspective view of the parallel bar;

Fig. 6 is a detail perspective view of the gauge block; and

Fig. 7 is a detail perspective view of the adjustable supporting block for the parallel Similar characters of reference indicate corresponding parts throughout the several views and-having reference now to the same:

1 is a fiat table forming part of a casting machine of well known construction upon which slugs are out from a slug bar 2 that is formed in a continuous strip by a portion of the casting machine which, being of well known construction, is not included in the drawing. In the mechanism shown in Fig. 1, 3 is a longitudinally movable rod mounted in brackets 3, and 4 is a knife housing in which is positioned a reciprocable knife 5,

the housing being fixed on the rod 2 by means of a set-screw 6 so as to move therewith. A

bracket 7 adjustably'fixed on the rod 3 and supports a gauge 'block8 that is adjustably fixed thereto. In the operation of the mechanism, as usual, the slug'bar formed by the casting machine in a continuous strip extends through the housing 4:" and is progressed onto thetable in a succession of advancing movements and contacts with and moves the gauge block 8 so that the rod 3 and knife housing are moved accordingly to the position indicated in dotted outlines. When thus moved, the knife 5 is brought into the path of a reciprocating presser9 which forces the knife inwardly so as tos'ever the bar 2 andform the slug 1O. During the operation the severed slug is' moved. away from the guide 11' out of the path of the slug bar 2 so that the slug bar mayprogress on to the table. When the knife is withdrawn the housing and its appurtenances automatically return to normal position in the usual manner. The" operation described is 7 of known practice,however, commonly the slugs as they are severed from the slug bar are permitted to fall over onto the table and accumulate in disorder, necessitating constant attention of the operator in arranging the slugs in stacks by hand.

The present invention is comprised of an attachment consisting of a guide 12' that is their rear ends and maintain parallel relation with each other as their opposite ends are actuated respectively by the movable slug cutting mechanism above described, so that the space between the guide and parallel bar is uniformly maintained during their movement.

A sliding bracket 20 is mounted upon the guide 12 and has a tongue 21 that bears frictionally against the guide, and also an outwardly extending win .22 is provided with an adjustable extension plate 23 which serves as a stop for theslugs as they are formed and moved onto the table so that the slugs are held in position upon their ed es.

:1 the operation of the invention the gauge block 8 is adjusted to a position according to the length of the slugs to be cut. and the adjustable block 18 is positioned on the rod 19 so that the bar 16 will be parallel with the guide 12 the stop 22 is positioned at the inner end of the guide by moving the slide 20 accordingly. The casting machine and the cutting mechanism are then set in operation and as the slugs are cut from the slug-bar and moved upon the table in successive order they are held endwise between the guide and parallel bar and bear sidewise against the stop so that they are retained in an orderly rank. The stop, being held frictionally in position by the slide, is moved accommodatingly backward as the slugs accumulate on the table without permitting the slugs to topple over in disarrangement. When the space between the guide and parallel bar becomes filled the rank of slugs is lifted by the operator in such groups as are convenient to handle at a time, and the stop is repositioned against the first of the remaining slugs.

What I claim is:

1. In an attachment for a slug machine having a table and a movable cutting mecha nism, a guide having pivotal connection at one end with the table and at its opposite end with the cutting mechanism; a slide having a stop thereon and being frictionally engaged in connection with the guide; and

a bar arranged in parallel relation with the guide and having connection at one end with the cutting mechanism and pivotal support at its opposite end.

2. In an attachment for a slug machine having a table and movable cutting mechanism, a pair of parallel members extending over the table and having connection with the mechanism so as to be actuated thereby; and a stop having frictional support on one of the members and being adapted to hold the slugs in edgewise position upon the table as they accumulate thereon between the members.

3. In a stacker attachment for a slug machine having a table and a movable cutting mechanism, a pair of parallel members spaced apart and pivotally supported at one end at one side of the table and connected at their opposite ends with the movable mechanism to be actuated thereby; and a movable stop extending between the members and adapted to hold the slugs in edgewise position upon the table in the space be-- tween the members.

In testimony whereof I affix my signature, in presence of two Witnesses.

WILLARD E. PRESSLER.
