R. BUTTE-RWORTH.

DIE. No. 340,976.' Patented May 4, 1886.

NrTnD STATES ROBERT BUTTERVVORTH,

PATENT Ormea.

OF SOMERVILLE, ASSlGNOR, BY MESNE ASSIGN- SPECIFICATION forming part of Letters Patent No, 340.976, dated May 4, 1886. Application filed June 6, 1885. Serial No. 167,847. (No modcl.)`

To all whom it may concern:

Be it known that I, ROBERT BUTTERWORTH, of Somerville, in the county of Middlesex, State of Massachusetts, have invented a certain new and useful Improvement in Dies, of which the following is a description sufiiciently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a diagram showing the method of cutting the collars; Fig. 2, a plan view of the under side of the upper die or force; Fig. 3, a vertical transverse section of the same, taken on line :v x in Fig. 2; Fig. 4, a plan view of the lower or bed die; Fig. 5, a vertical transverse section of the saine, taken on line y y in Fig. 4.

Like letters of reference indicate corresponding parts in the different gures of the drawings.

My improvement relates more especially t6 that class of dies which are employed in cutting paper and cloth-faced paper collars; and it consists in a novel construction and arrangement of the parts, as hereinafter more fully set forth and claimed, the object being to produce a more effective device of this character for certain kinds of work than was in ordinary use prior to iny invention.

The nature and operation of the improvemeut will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the upper die or force; B, the stock or holder for the same; C, the lower die, and D the bed for the same.

Thelower die, C, consists,in part, of two dies', m m, which correspond approximately in form or outline with the adjacent sections or halves of two collars placed end to end, and are attached to the bed D by screws a, the cuttingedge of each of these dies extending from o to i, and thence to z. Each of the dies m is also provided with a creaser, b, for creasing or indenting the collar on its folding-line in the usual manner; also with an embosser, d, for producing imitation stitches around the flap, and with holes r o, for receiving corresponding punches on the upper die for punching the button-holes in the ends of the band. Aclearer, f, provided with two downwardly-projecting studs, (not shown,) which work in corresponding holes in the bed D, is disposed adjoining the cutting-edges c, the clearer being provided with suitable springs, g, for raising it after being depressed by the upper die.

The embossers d and creasers b are flush or on the same plane with the cutting-edges z fi o and elearerf, all of these parts being elevated above the bed D about three-fourths of an inch.

A die, t, provided with a hole, w, for receiving a corresponding punch on the upper die, is secured to the bed D, opposite the ceuter of the clearer f, for punching the buttonhole in the back of the collar-band. There is also an auxiliary die, j, secured to the bed D 7o by screws 14 near its right-hand end, said auxiliary die being adapted to work in conjunction with a corresponding die secured to the holder B, for trimming the collars, as hereinafter described.

The upper die, A, consists in part of the die h, die k, embossers Z Z, creasers n, auxiliary die p, and punches ce Q. The die h is secured to the stock B by screws 20, and provided with a cut-ter, s s, corresponding with the cut- 8o ters zz of the lower die. The die k is provided with a cutter, a, at either side,which extends to the cutter s, the cutter a corresponding with the cutters o of the lower die.

The embosscrs l Z and creasersn a of the upper die respectively correspond with the embossers d d and creasers b b of the lower die, and are secured to plates 2 2, attached to the stock B by screws 24. The punches e e are adapted to enter the holes r in the lower die, 9o

and are designed for punching the buttonholes in the ends of the collar-baud, the punch q being adapted to ententhe hole w in the die t, and designed for punching the button-hole in the back or center ol' the collar-band, all of 9 5 said punches being secured to the holder B. Projecting from the face of the die k, near its front, there is a cutter,'25, adapted to iit a slot, 27, formed in the inner edge of the clearer f, said clearer subserving as a bed-die for said cutter.

The dies are designed to-be used in cutting IOS collars from the side of a sheet or strip of paper or cloth-faced paper, E, one-half each of two adjoining collars being formed at the same time, as shown at H J in Fig. l, the dotted lines in said figure showingthe method oflaying out the work to save stock. In cutting the collars said strip or sheet is placed on a table or platen, (not shown,)in which the beddie is set, and is fed to the dies intermittently, being moved from right to left about the length of one collarat a time, and secured to the table while at rest by pins, (not showin) which pass upwardly through holes 29 in the paper, these holes being so disposed as to come in the waste pieces 34 between the ends of the collars along one edge of the strip or sheet. In order to form the ends of t-he collar-bands properly, or to have them turn upwardly, as shown in Fig. l, when collars are cut in this manner, a small triangular waste piece, 35, is necessarily left adhering to the center of the collar-flap of each collar in the next succeeding row or series of collars, these pieces being trimmed off by the auxiliary dies p j in advance of the main dies A C. For instance, in Fig. l the piece marked 35 on the extreme outer edge of the strip or sheet E will be removed at the next advance of said strip to nish Vthe collar J and cut the rst section or half of the collar K. The waste-piece 3-1 is connected with the piece 35 by the narrow strip of paper 39, which comes between the ends of the bands of t-he collars, and the piece 3l, unless separated therefrom, will be dragged along with the strip or sheet E as the same is fed forward over the table, and therefore interfere with the work. It has, however, been difficult to separate these pieces at the right time and in a perfect manner without greatly complicating the machinery or wasting stock on account of the narrow space between the ends of the bands and the liability ofinterfering with the cutting-edges of the dies at that point, and also with the working of the clearer. To obviate this difficulty I make use of the cutter 25 on the die 7c, and construct the clearerf with the notch 27 for receiving said cutter, the notch having cutting-edges around its closed sides, so that as the upper die, A, descends the cutter 25 will separate the pieces 3i and 35 by bisecting the narrow strip 39 before the clearer is depressed by the die l1y or the other cutting-edges ofthe dies are brought into operation. The cuttingedges of the dies h It: p stand about an inch and one-fourth from the face ofthe stock B, and the point of the cutter 25 about an inch and threeeighths from said stock.

It has been usual, when cutting a series of paper or cloth-faced paper collars end to end7 7 from astrip orsheet, to die77 the stock outinto narrow strips, as shown in Fig. 6, and then cut it up into collars, the first process forming the side edges of the bands and iiaps, doing the creasing and embossing, and punching the center button-holes, and the second punching the end button-holes and removing the pieces 34 and 35, thereby cutting the strip up into collars.

My improvement enables the collars to be eut directly from the side or edge ofthe sheet of paper by a single process, thereby greatly reducing the cost of manufacture, and avoidirg the liability of soiling or injuring the stock by too-frequent handling.

It will be observed that one of the distinguishing features of my improved die consists in so constructing andai-ranging the parts as to cut'one-half each of two collars conjointly.

For convenience of reference, all ofthe parts attached to the face of the holder B, except the die p and punches e q, are denominated the die A, and all of the parts attached to the face of the bed D, except the dies tj and clearer are denominated the die C.

It will be understood that the bed D is to be properly mounted in a table or platen, and the follower and dies used with a suitable press and operative mechanism.

As I propose to make the process of cutting or manufacturing collars substantially as described the subject-matter of other Letters Patent, (for which I have filed an application under date of June 9, 1885, Serial No. 168,192,) I do not claim the same herein, lthis application being confined to the dies.

Having thus explained myinvention,what I claim isl. In a lower or bed die for cutting paper or cloth-faced paper collars, the combination of two cutters, each adapted, in conjunction with a suit-able upper die, to cut one-half of a collar, said cutters being arranged substantiall y as described, so that the parts which cut the ends ofthe collar band and iiap will be in juxtaposition, suitable creasers and stitch-embcssersfor each of the halves of the collars being cut by said cutters, and a clearer, all constructed, combined, and arranged to operate substantially as set forth.

2. In an upper die for cutting paper or cloth-faced paper collars, the combination of two cutters, each adapted, in conjunction with a suitable lower die, to cut one-half of a co1- lar, said cutters being so arranged that the cutters which cut the ends of the collar band and flap will be injuxtapositiomsuitable creasers and a clearer for said cutters, and a die adapted, in conjunction with a suitable lower die, to cut out the waste pieces upon the ends of the bands and iaps, substantially as described.

' 3. In a die for cutting paper or cloth-faced paper collars, the cutter 25, in combination with the die k, the clearer f, having the notch 27, and springs g, substantially as and for the purpose specified.

4. In a die for cutting the halves of two paper or cloth-faced paper collars, the die 7L, embossers Z, creasers a, punches e e, and die k, constructed, combined, and arranged to complete the formation of said-halves at one operation, substantially as described.

5. In a die for cutting paper or cloth-faced pa- ICO IIO

per collars7 the dies m, creasers b, embossers d, said creasers and embossers acting on the parts of the collars out out, and the clearer f, provided with the notch 27, all said parts 5 being constructed, combined, and arranged to operate substantially as set forth.

6. In a die for cutting out and completing the formation of the halves of two paper or clothfaced paper collars whose ends are in [o juxtaposition, the combination, with the dies A C, of the auxiliary dies p j, adapted to cut off the waste piece between the ends of the bands of the two halves of collars being cut out, substantially as and fortho purpose set forth. r 5 7. In a die for cutting paper or clotlrfaced paper collars, the dies A C jp t, punches q e, holder B, and bed D, constructed, combined, and arranged to cut out and complete the formation of the two halves of two different col- 2o lars whose ends are in juxtaposition, substantially as described.
