TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES SPoEEoRD, of Boston, in the county of Suffolk, and State of Massachusetts, have invented an improved Adjustable Cutting-Die, of which the following is afull, clear, and exact description, reference beinghad to the accompanying drawings, making part'of this specification, in whioh-' Figures l, 2, and 3 are perspective views, representing thc male and female portions of my adjustable dic for cutting paper collars.

Figure 4 is a longitudinal section, and

Figure 5 a transverse section, representing the two dies in a position for cutting out the collar.

My invention relates particularly to certain improvements in a die for cutting paper collars, for which Letters Patent of the United States were granted to George K. Snow, on the 28th day of November, A. D. 1865. His said invention consisted ina pair of dies, the adjustments of which, to adapt them to cut collars of varying sizes, were'performed with diiculty, and consumed much time, owing t0 their complicated construction and theirl position in the machine, while the outer-ends only of the collars were cut by them, the division of'one collar from another on the line forming the lower edge of one and the upper edge of the other, being performed by another die or cutter at a separate and subsequent operation. 1 A

My invention consists in a single die, which cuts out the entire collar, or other article of paper, or other material at a single operation, the male portion of the die being composed lof sections, which are secured to the plunger, the outer sections being moved and adjusted longitudinally to and from each other, andthe space between them being occupied by a block of the size required to form the collar of the right length, while the female portion of the die is also formed in sections, so that its size may be varied to correspond with that of the male portion of the die, by which construction I avoid the expense incurred in making separate dies for each size of article to be out, in a more simple andv convenient manner than bythe employment ofthe dies referred to in the above-mentioned patent. l y t To enable others skilled `in theart to understand and, use my invention, I will proceed to dcscribe-the manner in which I have carried it out. v l A In the said drawings, Awrepresents the head of the plunger, to which is screwed the male portion B of a die for cutting paper collars, composed of three pieces or sections, C C D,a longitudinal strip, a, serving as a guide, being interposed between the sec-tions and the plunger, to admit of the outer sections C C being slid thereon to obtain the length of collar required, suitable slots, b, and screws c, being provided to enable the workman to secure the sections immovablyin place when adjusted, the space e f between them being iilled by a. block, D, fig. 2, which is fastened to the guide a by a screw, g, and is readily removed therefrom to allow a block, E, of a diie'rent size being substituted therefor. (See fig. The upper and lower lines hz' and k Z of the die, corresponding tothe upper and lower edges of the collar, are made straight, and parallel to each other, and the construction of the guide on which they slide is made to correspond thereto, but when a collar is required whose upper and lower edges are curved, itis simply necessary to employ a curved guide. The female portieri ofthe die consists of two end pieces, H, resting on a bed-piece, I, provided with an opening, m, whose width is equal to v the width of the male portion B of tlie'die, and consequently that of the collar to be cut. Steel strips .I K are screwed firmly to the bed-piece, and serve as ways, within which the end pieces I-I are made to slide longitudinally, so that they may be fitted snugly to the male portion B, after it has been adjusted to agiven size of collar, the female portion,when fitted, being pressed against the strip .I by set-screws n, thus preventing any lateral displacement, and being held down immovably upon the bed-piece by bolts o passing through slots and tightened by screw-nuts r. lhe edge L z' of the several sections composing the male portion of the die is slightly bevelled, as shown in figs. 2, 3, and 5, to insure a shearing cut.

Instead of constructing'the male portion B of the die in sections, it may be made in one piece, and a die i of al different size be employed, whenever a collar of diiercnt size is required, the female portion only of the die being made adjustable. l

I have referred in the above description to a die for cutting paper collars, but itmay be, cons.ructed in any form to adapt it for cutting ont a variety of articles,`either in metal, cloth,.or other material.

I C'Zaz'm.

What I claim as my invention, and desire to secure by Letters Patent, is The within-described adjustable die, constructed substantially as and for the purpose set forth.
