1h all-whom it may concern Be it known that I, JAMES R. Cox, a citizen of the United States of America, and a resident of Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Punch-Presses, of which the following is a specification.

Thislinvention relates to punch presses, and the specific embodiment thereof which will be hereinafter described is, particularly designed for cutting notches in the edges of the anchor plates which are used for supporting the rules for printing tabular column lines in connection with linotype forms. The structure and method of securing these rules will be hereinafter briefly described, but will not be claimed, as they are made the subject matter of my copending application, Serial No. 640,252, filed July 24th, 1911. As these rules usually consist of extremely thin prismatic metal bars, it is of the utmost importance that the recesses in the anchor plates in which the rules are secured be exactly alined, and as the spacing of the rules must be capable of variation to suit the requirements of any particular job, it has been found necessary to devise a, special form ofpunch press for cutting the recesses having special means whereby the spacing of punches may be readily adjusted and whereby the setting of the punches may be gaged direct from the linotype slugs in connection with which the rules are to be used.

The main objects of this invention are to provide an improved form of multiple punch press wherein the punches may be readily adjusted with respect to each other, and wherein accurate alineinent of the punches and their respective dies will be positively insured; to provide a punch press of this class which is particularly suitable for cutting recesses in cross rules and anchor plates to be used for supporting column rules in a printing form madeup of linotype slugs; to provide an improved arrangement of parts of the press whereby the setting of the punches may be gaged direct from the linotype slugs;'and to provide improved means plates in position press so as to infor clampingthe anchor on the bed of the punch sure accurate registration of the column rule 7 recesses of successive anchor plates, regardless of whether such anchor plates are of a Specification of Letters Patent. Application filed September 5, 1911.

width suitable to enable them to serve as cross rules, or are of reduced width, so as to be below the printing surface and to serve merely as securing means for anchoring the column rules. i

An illustrative embodiment of this invention is shown in the accompanying drawings, in which Figure 1 is a perspective view of a punch press constructed according to this invention for use in' connection with the assembling of linotype printing forms for tabular work. Fig. 2 is a sectional detail taken on the plane of the irregular line A-A of Fig. 1. Fig. 3. is a fragmentary perspective view showing the kind of printing form which has been made commercially practical by the use of the device shown in Fig.1. Fig. 4 is a section taken on the line BB of Fig. 1. Fig. 5 is a section taken on the line CC of F 4. Fig. 6 is a detail in perspective of one of the clamp jaws which hold theanchor plates in position upon the bed of the press while the column line recesses are being cut. Fig. 7 is a detail in perspective ,of the punch. Figs. 8 and' 9 are details respectively of the wide and narrow anchor plates.

The printing form represented in Fig. 3 ismade up of the usual cast slugs a representing a line oftype, column rules 6 consisting of'fine triangular bars which rest on the upper faces of the slugs so as to provide an upstanding printing edge, and anchor plates 0 and d which are of two widths. The plate a is of a width equal to the type height so that its upper beveled edge will lie in the same the column rules 1) and will thus serve as a cross rule, and the plate (I is of narrower width so that its upper edge will be below the printing surface. In making up the form, the column rules 6 are inserted through dovetail recesses in the upper edges of the anchor plates. The hereinafter described machine is especially designed for cutting these recesses.

In the construction of the machine shown in the drawings, the main frame comprises a bed plate 1, uprights 2, and across bar 3 connecting the upper ends of the uprights 2.

There is a series of punch units 4 mounted between the bed 1 and the cross bar 3 and each'of the units 4 comprises a sub-frame or along .the bed. Each of the punch units is slidably mounted to fit between the cross bar 3 and'the bed 1. This is preferably accomplished by means of wedge-shaped guide ribs 7 and grooves 8, so that when the cross bar 3 is fastened in operative position on the uprights 2, all of the sub-frames 1 will be clamped against lateral displacement. In the form shown, the cross bar 3 is connected with the uprights 2 by means of bolts 9 threaded at their upper ends and carrying wing nuts 10. The apertures for the bolts 9 are counterbored at the upper ends of the uprights 2 so as to provide seats for springs 11(Fig. 4) which, when released, lift the cross bar 3 clear of the sub-frames of the punches and allow the punches to be adjusted freely relatively to each other.

Each punch 5 is carried b an enlarged plunger or shank 12, whic is slidably mounted in the sub-frame and is normally urged to a raised posit-ion by means of a spring 12 (Fi 2), seated in a counterbore in the subrame, and bearing against a collar 13 on the shank 12. -In the form shown, turning of the punch 5 is prevented by a pin 12 engaging a slot 12 in the shank. The shank 12 is provided with a head 14 at its upper end, which engages a cross head 15, by means of which all of the punches are operated in unison. The cross head 15 is guided in the uprights 2 to have vertical movement, being normally urged to its lifted position by means of springs 1'6 and being forced downward during the punching operation by means of a cam 17 having a hand lever 18, said cam being pivoted on the cross bar 3.

In order that the recesses in the anchor plates will be in exact alinement so as to insure that the column rules will be straight when the form is assembled, the bed 1 of the-press is provided with an L-shaped guide 19 having a gage shouder 20 disposed in parallel relation with the line of punches and a second gage shoulder 21. at right angles to the shoulder 20, and extending between the shoulder 20 and the row of punches. The

shoulder 20 is spaced from the dies a distance which is exactly equal to the height ofthe type bars, exclusive of the raised letters thereon. The shoulder 21 is the zero line with respect to which the punches 'are'adjusted. The column rules I) are of aheight equal to the height of the printing surface above the uppler surface of the type slugs, and the punc es are of the'same sectional area as the column rules so that the recesses which are cut thereby will be a close fit for the rules and rigidly hold them against distortion or displacement. Each of the punch sub-frames 4 is provided on its front face with a ruling or indicator line 22, which is vertical, and lies in a plane extending through the axis of the punch and at right angles to the base gage shoulder 20. These indicator lines enable the operator to adjust the position of the punches by standing one of the slugs in an upright position front of the row of punches with its end abutting against the gage shoulder 21, and

then setting the punch sub-frames so that their respective indicator lines 22 will correspond to the positions in which it is desired to have the column rules in-the form.

In order to insure that the anchor plates will be uniformly punched, clamp jaws 23,

one for each punch, are mounted on the punch sub-frames 1n position to engage the anchor plate and force it against the gage shoulder 20. These jaws 23 are forked at their front ends so as to allow the punches to pass through them, andtheir rear ends are seated in guide grooves 24 in the subframe blocks 4. This arrangement of the jaws 23 renders them adjustable with the punches and therefore avoids their interfer- Y ing with the adjustment of the punches.- A rod 25 extends through each of the clamp jaws 23 and through slots in the uprights,

2 and is normally urged to the forward limit of its movement by springs 26. This rod controls the position of the clamp jaws, as

will appear from Figs. 1 and 2. The jaws 23 may beshifted at will 'to their retracted position by means of a pair of arms 27 carried by the shaft 28, extending through the frame from end to end, one of said arms 27 being provided with a handle 29.

The operation of the device shown is as follows :After the slugs a have been cast, preparatory to making up the form, one of the slugs is placed upright on the base 1 of the unch press in front of the row of ,punc es and is pushed toward the left of Fig. 1 until its edge abuts firmly against the gage shoulder 21. The wing nuts 10 are then released so as to release the cross bar 5,

from clamping engagement .with the subframes 4 of the punches, and the punches are then shifted so that their indicator lines 22 willoccupy positions with respect to the slug corresponding to the desired location of j j column rulings in the form. Then the nuts 10 are screwed down, causing the punch frames to be securely clamped through the wedging action of the ribs 7, insuring that each punch takes a position exactly in a vertical plane at right angles tothe bed plate and gage shoulder 20. The slug is now removed from the base and may be replaced in, the form. The machine is now ready for cutting the recesses in the anchorplates 0,11. One of these at a time is placed in position so as to lie flat upon the bed 1 with its bottom edge bearing against the gage shoulder 20 lmaaei late firmly against the gage. shoulder 2O.

taneously operating all of he recesses are thenpunched by pushing down. onthe handle 18 and thereb simulthepunc es. In

' this way, each of the anchor plates is punched and itis immaterial whether the anchor plate is of the wide or narrow form, the position of the perfora-tions is gaged from the bottom edge of since in either case,

the anchor plate? In the anchor plates '0 which serve as cross-rules, the apex of-the triangular holewill lie exactly in the upper edge of the plate, whereas, in the anchor plates d, Which do not rint, and which serve.

merely for securing t e column rules, the apex will lie outside of the edge of the plate and the front part only of thepunch will penetrate the plate. v
