' IMPROVEMENT IN PAPER-COLLAR MACHINES.

' Specification forming part of Letters Patent No. 5 l ,233', dated November i8, 1865.

To all whom it may concern:

Beit known that I, GEORGE K. SNOW, of Watertown,`in the county of Middlesex and State of Massachusetts, have made a new and useful invention having referenceto'cutting or stamping shirt-collars from a'strip of paper or other material 5 and I do hereby declare the same to be fully described .in the following specification and represented'in the accomfemale end and button-hole-die plate. Fig. 7

is a top View, and Fig.8a longitudinal section, of the central button-hole-die plate.

`This machine is intended to stamp out neckcollars from a continuous roll or strip of paper of a Width corresponding to that of a collar to be made from it. Fig. 9 exhibitsthe arrangement of such collars in the strip, or the cutsV made in such strip'iu order to reduce it to collars-th at is to say, the short pieces e, being cut from the strip at equal or proper distances apart, leave collars A A. Each of these co1- lars has a central button-hole, c, and two'end button-holes, d d, stamped through it by the machine. With 'the exception of the small pieces necessary to the formation of the button-holes, parts such as are marked ein Fig. 9 are all that it is necessary to remove from the strip in orderto convertitinto collars. In this way of forming the collars from a strip it will be observed that the end of each collar extends by that of the other, and goes close, or nearly close, up to the upper portion of the Vsaid-other collar. This peculiar arrangement vof the collars or their ends I claim to be new and of my invention,as well as the machine forfcutting or-stamping such collars in such manner from a strip.

-In the drawings,A denotes the bed-plate of the machine, which 'is dovetailed into the cutv ter-carriageB, or so applied to it'as to en able the die-plate C. Suitable openings,h t', are formed in the carriage B and the bed-plate A, in

order to lallow the waste separated from the striplby the dies to be discharged from the plate C.

Y The opening 'i' between the two platesj'gis the female die, by which the ends of the collars are formed through the action of a corresponding male die, 7c, projecting from the bottoni of a plunger, D. (See Fig. 2.) The said plunger plays vertically within a box or frame, E, (fastened to the carriage B and on the top surface of the die-plate C,) and has a cross head or bar, Z, bolted across its top and resting on .springs m m, which, in turn, rest on two ears or projections, n n, extended from the ends of the box E. `(Spee Fig. 3.) The purpose of the springs on ,in is to eli'ect the elevation of the plunger I) and the Withdrawal of the male die It from the female die t" at the proper periods.

There are two female button-hole dies, o o', formed through `the plate f, and there `are also two other female button-hole dies, o 0, formed in the plate g, they being arranged as shown in Fig. 5. Corresponding male dies should be projected from the bottom of the plunger D, so as to enter and operate with the female dies o o o o in a manner analogous to that in' which the male die k operates with the female die t. Furthermore, there is applied to the car'- riage B adjustable button-hole dies for cutting or stamping from the strip, the middle buttonhole. dierepresented at c in Fig. 9. The fe male dies of these lastmentioned button-hole dies are shown pin Fig. 7 as made inand through a rectangular plate, F, which is arranged on the upper surface of the carriage B, and so as to be capable of being slid thereon between two parallel guides, q q, arranged on' the said carriage in manner as represented in Fig. l, 2 and 4.'

Corresponding male dies projecting from the plun gers r r, extending downward from a crosshead, s, operate with the said female dies p p, one-ot' such male dies being shown at t in Fig. 2. f i

The twoplungers r r play within a standard, u, which projects upward from the plate y F, and has a long screw, G, screwed through 'y it, and so connected with the box E that-on revolving the screw the distance of the dieplate F from the die-plate G may be either increased or dii'ninished, as circumstances may require.

Lassagesiv l1n for discharge of the Waste from the dies j; p are made through the carriage Ii andthe bed-plate A.

The bar s rests on springs fr, which, in turn, are supported onv ears y y, the same being as shown in liig. 4, the said springs being for elevatingl the dies 1 out of the die-plate F after each descent ot' such dies.

`Ih con neetion with the mechanism described, I malte use of au adjustable gageplate, H, carrying two projections, s z, which are arranged. on and so as to extend from it, as shown in Figs. 1,2, and 3. This gage-plate slides rectiiinearly on the carriage l5, and is provided with a clamp-screw, a', by which it can be iixed in position on the carriage and with reference to the end dies. A straight rib, 1,',p1oiecting downward from the plate H, euters a groove, c', made in the carriage, and at right :ingles with the outer edge. of the platef. The clamp-screw a passes through a groove, d', formed in the plate II, and screws into the carriage.

lt is on one o." the proicctions or guards c that the middle bntton-holeofeach collar, prior to the separation of such collar from the strip,

. is placed in order to determine the correct position ofA the lstrip for the end dies to operate in order to out the said collar therefrom. As the middle button-holes of each two next adpaper are not at the same edge of the strip,

but are situated at opposite edges ,of it, in4

manner. as shown in Fig. Si, it becomes necessary that theprojections z .1: should be used alternately dnring`the process of forming the collars by the machine.

In going through the machine the strip of paper passes underneath the standard a and the box E and rests on the dic-plates C and Ii, and is to be fed along with an intermittent motion. Ireviousto each descent of the male dies the carriage I3 is to be moved laterally, so as to transfer the paper from lone side ot' the middle line ot' the carriage to the opposite side thereot.

Ihe mechanisms for so moving the carriage,

'and for feeding the strip of paper along, and

dies; also, that the two sets of each kind of thc dies are arranged on opposite sides ot' the middle line of the carriage B.

What, therefore, I claim as my invention in the said machine isi 1,. The above-described arrangement and combination ot' endend button-hole dies, irrespective of the middle button-hole dies.

2. The above-,described arrangement and combination of end and button-hole dies, in-

clusive ot' the middle button-hole dies.

'3. In combination with the end dies and the middle button-hole dies, arranged as specified, a mechanism for adjusting the distance of the said middle button-hole dies from the end forming-dies. i f

4. In combination with the end cutting-dies and the middle button-hole dies, arranged as described, the gages z e, whether stationary on 'thecarriage B or adjustable thereon, a's specified.

v5. The end forming-dies, substantially as described, for shaping the contiguous ends ot' two collars at one operation.

6 The formation of collarsin a continuous strip in the' manner, or' with their ends to overlap one another, as hcreinbefore described, and as represented in Fig. t).

7. The formation of collars from a continu ous strip of paper, as described, by means of end forming-dies arranged as specified, and by alternately changing the strip from one `side to the other of the middle line ot' the dies, as specified.
