machine and adapated to be distributed to their proper magazines by the described mechanism, must have holes punched through them, said holes being arranged in two rows on all matrices. The different matrices, however, differ in respect tothe number and location of said holes in said two rows. In each row there are eight positions at which holes may be placed, and these positions are so close together that it is practically impossible to simultaneously punch two holes in contiguous positions.

This invention is a machine which is particularly adapted for punching any required combination of such holes in matrices of the character described; 01 ,.more exactly, perhaps, it consists of additions to and combinations of new arts with an ordinary punch press by which such press is adapted for the stated work, all of which is hereinafter described, and is definitely pointed out in the claims.

In the drawing Figure 1 is a side elevation of the machine employing the invention. Fig. 2 is a vertical sectional view of one of the dies associated with the machine. Fig. 3 is a plan View of the machine when the reciprocating plunger and its supports and operating mechanism have been removed. Fig. 4 is a front elevation of the machine. Fig. 5 is a bottom plan View of the punch carrying block adapted to be secured to the reciprocating head of a suitable punching machine. Fig. 6 is a front View of said block. Fig. 7 is a side view thereof. Fig. 8 is a vertical sectional view through a part of said block; and Fig. 9 is a plan View of a matrix M, having holes which the machine is adapted to punch. Fig. 10 is a rear View of one of the locking plates.

The punch press may be of anysuitable form and construction, many of such machines being now in common use and suitable to be adapted for use with the present invention. Such machines include a vertically movable reciprocating head 1; a rotating operable shaft 2, and a connecting rod 3 connected with the crank on said shaft and with said reciprocating head.

A punch carrier at is to be secured to the lower side of the punch press head.v This punch carrier is a block built up, as vrequired, of several pieces; and has on its top a dove-tailed tongue 5 adapted to enter and -fit a dove-tailed groove in the under side of the press head. This punch carrier car ries two groups of punches 6. In each group there are eight punches arranged in two rows of four,-the punches of one row be ing staggered with respect to the punches in the other row. Th1s separation of the punches into two groups is rendered necessary'by the fact that the holes, which these punches are to punch in matrices, may be so close together that it is practically impossible to arrange the punches for punching holes in any of the sixteen places, where holes may be punched, in a single group. Each group, however, is like the other. group in respect to the construction of the punches and the means for maintaining them 1n operative or inoperative position, wherefore the description of one group will answer for both. It will be understood also from the foregoing,.that the punches of one group are provided and disposed so that they may punch holes at those points upon a matrix where the punches of the other group cannot punch holes.

The punches are fitted to vertical holes 8 in the carrier, the upper ends of these holes being extended into transverse recesses 9 in the carrier. WVithin these transverse recesses there are as many sliding stop bars 10 as there are punches, one of the bars being arranged above each of the punches. In the lower surface of each bar is. a notch 11 into which, when the bar is in one position, the associated punch may project; and when the upper end of the punch does project into said notch, the lower end of the punch may be raised to an inoperative position. One end of this notch is beveled so that, by push ing the bar lengthwise this beveled end of thenotch will engage with the top of the associated punch and push it down; and the bar will slide over the top of the punch, and thereby hold it down in operative position. These various bars 10 are parallel with each other and are in the same horizontal plane. In the top of each of these bars are two notches 12, 13 which are preferably of different depths. A locking bar 14: is arranged to enter one or the other of these notches in each of said bars. This locking bar is held in position by a spring latch 15. hen it is in operative position the lower edge of the locking bar will be in one of the notches referred to of each bar 10, and will therefore prevent endwise movement of all of said bars 10. There are, preferably, as many locking bars as there are different combinations of the bars 10 to be employed. In

each locking bar the deep and shallow notches are arranged in accordance with a predetermined arrangement of the bars 10. When the latter bars are ar anged properly for cooperation with a given locking bar, those bars 10, which lie beneath the shallow notches in the locking bar, must be drawn out so as to present their deep notches beneath said locking bar, and those bars which are beneath the part of the locking bar having deep notches must be pushed in so as to present their shallow notches for engagement with the locking bar. Unless the bars are arranged in this manner the locking bar will not descend far enough to permit its top edge to be engaged by the latch 15. Set screws 16 screw into the punch carrier, and project into little slots 7 in the sides of the punches, which slots are long enough to permit of the required motion of the punches as explained.

In order to adjust the various punches the locking bar 14: is removed. Then each one of the stop bars 10 is moved as may be required to either force its associated punch downward into operative position, or to permit it to be pushed upward out of the operative posit-ion, with its end projecting into the notch in the lower face of the associated bar 10. Vhen in either position one of the notches on the top of each bar may be alined with other notches so that it and they may receive the lower edge of the locking bar whereby these bars 10 are held against endwise movement.

Upon the bed plate 17 of the machine two magazines 18, 19 are secured; and located below these magazines is a rotating plate 20 through which are numerous holes 21 which correspond in size with the matrices. lVhen this rotating plate is in one of the positions in which it comes to rest, one of these holes is directly under the feed magazine, wherefore the lowest matrix in said magazine drops into said recess, and rests upon the bed plate of the machine. At the same time, another hole 21 diametrically opposed to the recess first mentioned, is beneath the other ma azine. This rotating plate is moved intermittently distances equal to the angular distance between the said holes; and as it. moves it carries along with it the matrices in said holes, said matrices resting upon the bed plate. \Vhen the plate 20 stops, two of these holes and the matrices therein are directly under a group of punches, and directly over a die set into the bed plate of the machine. It is of course while this plate is at rest in the positions stated, that the punch head descends, with the result that both groups of punches punch holes in the matrices beneath them. It is at this time also that the bottom matrix from magazine 18 drops into a hole 21. in plate 20. and that a finished matrix is pushed out of a hole 21 and up into magazine It).

The intermittent movement of plate 20 may be produced by suitable mechz'inism such as that which the drawing shows, as follows: In the edge of this plat are numerous shoulders 22 which are adapted to be successivelyengaged by a pin 31 carried by a reciprocating slide 30. This pin is not secured directly to the slide, but to a lever 32 which is pivoted to the slide, and is subject to the influence of a spring 33 which tends to swing it so as to carry the pin 31 thereon against the edge of plate 20, and therefore into the range of one of said shoulders 22. hen the slide moves in one direction the pin engaging with an inclined surface 23 on the edge of said plate adjacent to said shoulders pushes the lever 32 back against the force of its spring until it passes the next shoulder, whereupon the lever 32 swings so as to carry the pin 31 into range with this shoulder. "When the slide moves in the contrary direction, this pin pushing against said shoulder, turns the plate 20 a distance which, as before stated, is equal to the angular distance between the adjacent holes 21 in said plate. hen the plate gets to the position in which it should be stopped, a bolt -10 is moved by a spring 40 shown in dotted lines in Fig. 1 in that direction which carries its tapered end into the adjacent tapered recess 2st in the edge of the plate. The taper on the end of this bolt is such that when force is applied to turn plate 20, the inclined edge of the recess 2%, engaging with the inclined end of the bolt, pushes this bolt back, wherefore this bolt, although when in a recess 24 will hold the plate against any accidental displacement, will not prevent the described movement of said plate.

The slide 30 is moved backward and forward by a. vertically reciprocating rack bar 3st, which is connected by a pitman 35 with a crank 36 on the press shaft 2, and a gear segment 37 which is engaged by said rack and has an arm 38, which is connected by link 39 with slide 30.

l l t) To the sides of receiving magazine 19, two springs 25 are secured, having at their lower ends fingers 25 which project into the magazine and have beveled lower faces. The matrices, as they come to rest beneath the receiving magazine are pushed up by a plunger 50. Each matrix engages with these fingers, and spreads and passes them. Thereupon these fingers spring inward beneath the matrix and thereafter sustain it and the pile of matrices resting upon it. The two magazines are shown securedto two bars 26, 27, which embrace a fixed vertical rod 29. A set screw 28 in bar 27 furnishes means for securing said bar to said rod at any desired elevation,-the advantage of this adjustability being that the magazines may be secured with their lower edges at a suitable 'elevation above plate 20 to accommodate matrices of different thicknesses.

The plunger 50 is moved upward by means of a lever 51. One end of this lever is in the path of a finger 52 secured to the punch plunger; or rather in the particular construction shown, to the carrier 4.
