SAMUEL CEUMP, OF MONTCLAIR, NEV JERSEY.

DIE FOR CUTTING PAPER, SLC.

SPECIFICATION forming part; of Letters Patent No. 348,548, dated September 7, 1886.

Application filed March 20, 1886. Serial No. 195,933. (No model.) V

T0 @ZZ whom it may concern:

Be it known that I, SAMUEL CRUMP, a citizen of the United States, and resident ofMont clair, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Dies forCuttingPaper, die., of which the following is a specification.

My invention relates to an improvement in dies for cutting paper or other material, the object being to provide a die which will at one operation cut the material, half cut the same ou certain lines, and score `it on others, on which it is to be folded in forming a box or other article.

A further object of my invention isto construct a die of practically one piece, and obviate the necesssity of forming separate blocks wherewith to hold the several sections of the cutting-knives and scoring-pieces together.

A further object of my invention is to provide a die which shall be simple and economical in construction, capable of being easily and readily formed, and which shall be durable and eflcient in use; andwith such ends in view my invention consists in certain novel features of construction, as will be hereinafter described, and pointed ont in the claims.

In the accompanyingdrawings, Figure l is a top plan view of my improved die. Fig. 2 is asectional view thereof on the line ab of Fig. 1. 3 is a top plan view of the templet.

For the sake of illustration I will describe my invention constructed to cnt blanks for paper boxes; but I would have it understood that I in nowise limit my invention to such appli cation, as dies construct-edili accordance with my improvement might be used for cutting veneers, labels, showcards, placques, 85e.

Referring to the drawings, A represents the base-plate of the die, on which rest the cutting-wires B, arranged to impart to the material being cut the proper outline. On the plate A also rest the cutting-wires C, the edges of which are located in a plane somewhat below that of the edges B, the'purpose of the cutting-wires C being to partially cut through the material of which the blank is formed on Vcertainlines on which the box is to be folded.

These cutting-wires B C are preferably made of hardened steel, in order to prevent losing their sharpened edges when they come in contact with the metallic plate on which the material being cut rests.

I) represents brass wires arranged to score the blank on the lines on which it is to be folded, the upper edges of these wires being located in about the same plane as that of the Wires C.

Upon the surface of theylt A is a coating of metal, Acelluloidor other material-serving to hold the cutting and scoring wires in po sition on the plate, the saidmetal or Celluloid serving as an anchorage for the wires, and also practically forms the die of one piece. This arrangement I have found far superior to the ordinary cutting-dies, which have generally been constructed of metal blades arranged in accordance with the outline to be given the blank and the brass scoring-rods all held in their proper relative positions by blocks, the whole being set up similar to a form of type and then bound or locked together.l It is very evident that the construction of this form of die involves a great expenditure of time and labor-as, for instance, in constructing a die of the Vform shownin the drawings-it was first necessary to arrange the metal blades similar to the wires B and C, then the scoring-pieces D, and then to form blocks to lit in between the blades and scoring-pieces.

It will be readily seen that to form blocks similar in contour to the polygon a, the triangle I), the triangle c, quadrilateral d, die., in order to hold the blades in position added materially to the cost and time of producing the die, and that by myimproved device these objections are entirely overcome.

In forming my improved die Ifust construct the templet E, which consists of a plate having grooves formed therein for the reception of the cutting and scoring wires, the grooves being formed to hold the wires in positions to impart to the blank the proper outline. In cutting these grooves, which is preferably done by a ruling-machine, care should be taken to form them of proper depths,the grooves f, for

the reception of the cutting-wires B, being of such depths as to receive wires slightly thicker than the material of which the blank is made, and the grooves g, for the reception of the wires G, being of such depth as to receive wires of such thickness as will partially cut through IOC the material. The cutting and scoring wires are placed Within their respective grooves and a coating of metal, Celluloid, or other suitable substance spread over the templet and Wires, the sharp edges of which nlatter are turned downwardly, the surface of the templet being rst coated,.if necessary, with a suitable ma teriahas soapstone or plumbago,to prevent'the metal from adhering thereto. The upper edges of the groove formed in the templet are beveled, for the purpose of allowing the metal or celluloid or other substance to partially en.-

Y ter the groovcs-and take a iirm hold of the Wires. A plate, A, is then placed on the layer or coating A, and the Whole subjected to heat and pressure, either orboth, according to the material of which the coating is composed un- `til said coating has entered the grooves and grasped the Wires, and also taken hold of the plate A. After this operation the die is allowed to cool and `then raised from the templet, the scoring and cutting wires having their baseedgesqemledcled in the substance of Which the anchorage is cmposedrgnd by virtue thereof held firmly to the baseYpiate,-,and,having scraped away the excess of metal, if any, from around the cutting-wires, the die is ready for.

use.

It will now be seen from the above description that my improved die can be constructed much quicker and much cheaper than ordinary dies used for the same purpose, and is not so liable to get out of order, as the anchorage of metal or other material forming one piece with the plate and Wire is more effective in holding the latter in position than the blocks heretofore describe( Several of these dies may be used conjunctively, and a corresponding number of blanks cut from a sheet of material at one operation, the edges of the cutting-Wire being preferably provided with a notch or notches to prevent said blanks from being entirely severed from the sheet of material.

I do not Wish to have it understood that I in anyWise limit lnysel` to any particular metal or substance for forming the anchorage of the Wires, as I might use any of the metals, celluloid, or other substances, butin forming my improved die I would recommend the use of the composition described in the patent granted to me, assignee, No. 336,590, and dated February 23, 1856, which may be spread on the templet in a powdered form, and by the aid of heat and pressure be transformed into a solid metal; nor do I Wish it understood that I make any claim in this application to the method of forming my improved die, as I reserve unto myself the ri ghtto make such the subject matter of a separate application.

That I claim as my invention, -and desire to secure by Letters Patent, is-` l. A die for cutting paper or other material, constructed of cutting-Wires arranged in proper relative positions, having their baseedges embedded in a plastic substa-nce hardcned to form a solid anchorage for the wires, substantially as set forth. Y

2. A die fofcutting paper and other material, constructed of a base-plate, scoring and cutting wires arranged in suitable relative positions, and a coating or anchorage attaching itself to the base-plate and embedding the base-edges of the wires and securing them in position, substantially as described.
