. To all whom it may concern:

Be it known that I, Laas H. Vow, a citizen of. the United States, residing. at Westvil'le, county of Gloucester, State of New Jersey, have invented a new and useful Improvement in Multiple Punches, of which the followin is a full, clear, and exact description, re erence being had to the accompanying drawings, which form a part of this specification.

In Letters Patent No. 833,811, issued to me October 23, 1906, is described and illustrated a multiple punching machine. In the machine of that patent a single "punchin bar is used, and while the punches are ad ustable with respect to each other, upon that punching bar, such machine has considerable limitations, both as to the character of holes capable of being punched and the longitudinal alinementof the arrangement of holes. I

- It is essential, for practical reasons, t-ha the punch holders shall be considerably wider than the diameter of the punches, thus for one inch-punches it has been found impracticable to make the punchholders less than two and one quarter inches wide. The width of the punch holder, therefore limits the distance between any two adjacent holes in the line transverse to the movement of the work. It is not practicable to move punches laterally between successive punchmgs and no two punches in the same row can be set closer together than the minimum, say two and one-quarter inches; therefore ot er provision must be made for punching holes closer together transversely than the minimum allowed by the punch holders.

Speaking generally, I accomplish this re- 'sult by using a plurality of rows of punches carried on one or more punching bars. \Vith two unching bars, each carrying two rows of a justable punches, I have a possibility .of four adjustments less than the minimum distance between any two punches in one row, or I can use punches of different diameters, even if they fall on the same longitudinalline with the other holes not of the under consideration, said punch bars are simultaneously reciprocated to and from the plate and the coacting dies, and when moved rom the plate, the work or plate is moved forward. As in my previous patent, each individual punch is controlled by a gag block operated b a pneumatic means, which in turn'is contro led by a perforated paper roll. For exam Ie, the space between sets of punches, on t e same bar, may be about six inches.

Where a number of holes are to be made by punches in diiferent sets or rows, it is necessary that the various punches shall be rendered operative at the moment when the proper point on the advancing plate shall be directly under the proper row of punches,

.and the perforated templet must be so preparedas to accomplish this result. For instance, if apunch in a given row is to punch a hole and another hole in thesame line is to be punched by a punch of another row of punches, separated from the first row of punches, by, say 36 inches, it is obvious that the second punch mustnot become operative until the plate has advanced 36 inches from the point where it was when the first hole mentioned was punched. To accomplish this the perforated templet must be so made that the second punch will only operate after the. plate has moVed 36 inches after the action of the first punch.

I will now describe the embodiment of my invention illustrated in the accompanying drawings.

Figure 1 is a side view of the machine, partially broken away. Fig. 2 is a front view of the machine partially broken away. Fig. 3 is a plan view of the machine. Fig. 4 is an enlarged sectional view of a unch bar. Fig. 5 is a front View of a portion of the bar shown in Fig. 4. Fig. 6 shows a drawing with the punch indications in the position the corresponding punch holes will appear on the plate. This drawing may represent an actual drawing, the lay out or the indications on the plate to be punched itself. F igl 7 shows a drawing inwhich the punch indications of Fig. 6 are arranged with respect to the distance between the rows of punches from which theyare to be cut. Fig.

8 is a diagram showing the relative position of the punch row or punch bar and the punch indications of each baror row.

e is the driving shaft driven by the gear 7...

On this shaft 9 are the eccentrics-g and h.

' .The eccentric goperates the lever z, and the eccentric h the lever j. The punch bar (1' is operated by the lever 2', and the punch bar I; operated by the lever j. The lever 2', resting on the intermediate bar. k, which bears on the punch bar a, is the connection for moving the bar a down. The connection to lift the punch bar a is through the bolt I, which rests on the top of the lever 2'.

and has-the links 722- which pass through the bar I: and are secured to the punch bar a. The punch'bar b is lifted and depressed by similar means, which are similarly lettered.

In ermediate of the rows of punches on an h bars a and b are the stripping memers 11. connected. to the rods 0 which in turn are connected to the levers. p operated by cam g on the shaft 6. This cam is set so that the stripping member moves downward ahead of the punch bar and clamps the work at the point of punching and retains the work clamped until after the punch bars are lifted sufiiciently to relieve the punch from the plate.

1' are the the punches.

s are the cylinders for operating the gag blocks and t are levers connecting the gag blocks and the-pistons of these cylinders. These levers and their mountings are novel vith this invention. They are so constructad that the gag blocks may be out of vertical alinement with the pistons or air cylinders which are fixed, and yet the device be operated. Generally speaking this is accomplished by mounting the levers so thatthey have a free movement in two directions. Specifically the construction is as follows: Corresponding to each lever is a bolt u on which ispivotally mounted a rectangular bearingblock 1: which has the bearing points 20. Through this bearing passes the lever t, which rests against these bearing points to, so that the block 4) can be moved on the bolt'u into proper position'and clamped securely by the said bolt. The lever t can then operate on the bearing points w as a fulcrum or axis. The position of the lever may thus, as desired, be made to conform to any adjustment of the punch with reference to its cylinder. Connecting the cylinders .s' with the air boxes (not shown) are the connecting-tubes cc, and theadmission of air or the closure of air from these pipes. and thus, the control of the operativeness of the punches individually, is accomplished bv means of a perforated sheet, all as fully de scribed and illustrated in my Patent No. 833,811.

gag bhicks, for rendering active I 3 are rollers in advance of the punches, and z rollers beyond the punches.

30 are the coacti ng punch dies.

10 is a movable stock carrier or member mounted on rollers 11 having integral there with at several points the cylinders 2, carrying the pistons 3, each piston is connected b a rod 4 with, a clamping lever 5, whic clamping. lever is, when the piston is lifted, adapted to clamp the stockiiarrier and plate together between the clamping lever ti and the abutment 25. This moving member or stock carrier I9- has upon'it the rack 6, which is operated by the gear 7. The operation of this gear 7 may be'by the same means as is used to operate the gears of the stock carrier described and illustrated in my Patent- Air is admitted to the cylinders 2 by means of a flexible connection 17. This flexible connection is connected with a source 7 of air under pressure and an exhaust orifice.

The moving member or stock carrier 10 has the oflset portion 40 forming a longitudinal straight edge, thus forming a gage line for setting the plate in its proper transverse position. Italso gives the operator a base from which to measure in locating the punches in the various rows.

'In the illustrations shown in Figs. 6, 7,

and 8, I have taken it that two punch bars separated by a distance of forty-two inches and two rows of punches on each bar separated by a distance of six inches are used. The Roman figuresdesi'gnate the row carrying the punch, corresponding to the indications, while the Arabic designation indicates the punch corresponding to the indication independent of what bar it may be on.

In the drawing, Fig- 7, all the indications II of Fig. 6, are moved back a distance equal to the distance between the first and second row of punches 2". e. a distance representing six inches. All the indications III of Fig.

6 are moved back a. distance represented by a distance between the first and second row sented by the last mentioned distance and a distance represented by the distance, six

inches, between the two rows of punches on the second punch bar, aggregating forty eight inches. Thus in the drawing of Fig.

7 the punch hole indications occupy the proper relative position with respect to each other, taking into consideration the distance between the rows of punches and punch bars. From this latter drawing, the perforated templet operating the pneumatic control of the gag blocks, may readily be formed in the ordinary manner. That is, the cutter in .transverse line of Fig. 7, and also the kevs corresponding to the s acing cutters for the distance between the rst and second rows of Fig. 7. On the next section of the templet the same method is carried out by the cutter ressing the keys corresponding to the num-' ers of the punches appearin on the second transverse line of Fig. 7 an valso the keys corresponding to the spacing cutters fort e distance between the second and third transverse lines of Fig. 7. This is precisely the method used with the single row of punches or sin le punch bar.

In Fig. 8 the rows of punches are designated I, II, III and IV, rows I and II being on the same punch bar and rows III and IV being on the same punch bar as each other, but on a different punch bar from rows I and II. The distances between rows of punches and unch bars are also indicated. In' the drawings and description I have treated the relative positions'of the indications of Fig. 7 as based on the first row ,of punches. This row becomes the key row for'the relative positions of the indications. I can use any other row of punches 'for the key row.

The drawing Fig. 6 is practically the lay a outand may bear drawing per se or any other form of indication of the lay out, for instance, the plateitself.

I do not claim herein the matter illustrated in Figs. 6, 7 and 8, as the same forms the subject matter of a separate application filed by me.
