IMPROVEMENT IN APPARATUS FOR MAKING PAPER COLLARS.A

Specification forming part of Letters PatentNo. 43,870, dated August 16, 1864.

To all whom it may con/cern:

Be it known that l, DAVID M. SMYTH, of the city, county, and State of N ew York, have invented certain new and useful Improvementsin Machinery for Making Iaper Gollars 5 and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specifi cation, in which- Figure 1 is afront elevation Fig. 2, a cross vertical section; Fig. 3, a face View of the lower press face or die and the opening through which the collars are dischargedv when cut, and Fig. 4 a face view of the upper press-face and the punch by which the colars are punched or cut.

The same letters indicate like parts in all the figures.

By my taid invention the edges of the collar are so cut as to present a better edge than by any other means heretofore employed for the purpose. The surface near the edge is embossed in imitation of stitching, and the parts are so combined that as one collar is being cut off, the surface of the paper is being embossed and the holes for the buttons punched for another collar. The collars are cut successively from a long sheet of paper, which is a little wider than the length of the collars to be made.

In the accompanying drawings, a represents a suitable frame, and b the bed, which forms the lower press face or die, c, and what may be termed the female 7 portion of the shears. rIhe lower die, c, is simply a flat, smooth face of metal. I prefer to make it of steel. There are three apertures, d d d, made in it of the form of the button-holes required to be made in each collar. These holes should be formed with sharp, square edges; and for the purpose of embossing the surface a short distance within the upper edge in imitation of the stitching, two line wires are twisted together and secured in a groove, as at c, the groove being made of such depth as to leave a sufficient portion ofthe diameter of the twisted wires projecting above the surface of the bed or die c.

Heretofore the imitation of stitching hasbeen. very imperfectly done by fine teeth cut in the edges of two thin plates inserted in the bed or die, which simply emboss two rows of of the collar when completed.

pointed indentations, notat all representing stitches 5 but by my said improvement, which consists, in this, respect, in substituting two wires twisted together, the embossing produced therebyT resembles very accurately the two rows of stitches. The twisted wires are to be placed to suit the shape of the collar to be made, so that the rows of stitches shall be at the required distance within the edge A mortise, j', of the size and shape of the intended collar is formed through the bed o, leaving the'upper edge square and sharp, andthis forms what I term the female 7 part of the shears. .lo this mortise is accurately fitted a plunger, g, which forms the male portion of the shears. This is secured to the Linder face of a follower, z, which is fitted to slide in suitable ways, t' t', of the frame, so as to slide accurately therein; and the lower face of this plunger g is beveled in opposite directions from the middle toward cach end, so as to give the cutting-ed ges thereof, in entering the mortise'or female [art of the shears, a shearing eut, so that by this and the accuracy with which which it fits the mortise the collars will be cut with a perfectly smooth edge, and without bending the paper, thereby avoiding a serious difficulty heretofore experienced. rIhe face of the follower h'by the side of the plunger should be smooth and parallel with the fa'ce of the die or bed c, and this is provided with three punches, d d d', so as to accurately fit in the apertures cl d d in the bed, to punch the button-holes. The follower receives an up-anddown motion from an eccentric, j, on a horizontal shaft, 7c or the required motion may be given by other and equivalent means. While the follower is up, the sheet of paper is pushed in by hand until its forward edge strikes two gage-stops, I l, on the bed c, and as the follower descends, a 'collar is cut or punched from the sheet and discharged through the mortise or female portion of the shears, while by the same operation the sheet of paper beyond is punched to form the button-holes, and the surface is embossed ready to be cut or punched by the next operation to complete another collar. In this way it will be seen that at each operation a collarl is completed and discharged.

What I claim as my invention, and desire to secure by Letters Patent, is
