IMPROVEMENT IN APARATUS FOR BENDING AND FOLDING PAPER COLLARS.

Specification forming part of Letters Patent No. 44640. dated October ll, 186i.

To all whom it mwy eww-erro:

Be it known that I, WILLIAM E. Locri- WOOD, of Philadelphia, Pennsylvania, have invented an Improvement iu Apparatus for Bending and Folding Shirt-Collars; and [do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in the machine for bending and folding paper collars, for which Letters Patent were granted to me as assignee of John F. Schuyler on the 24th day of February, 1863; and my improve ment consists in the use, substantially as described hereinafter, of two rollersone having a concave and the other a convex surface-in combination with a reciprocating plate, so that the line in which the fold is made shall be curved instead of straight, a collar thus folded having a tendency to bend oi' itselfand thus more readily conform to the shape ofthe wearers neck without that puckering which is apt to take place in collars folded in a straight line.

On reference to the accompanying drawings, which form a part of thisspeciiication, Figure 1 is a sectional view ofthe front end of the said patented machine with my improvements, Fig. 2, a transverse sectional elevation on the line l 2, Fig. 1; Fig. 3, a view of a collar prior to its being bent; Fig. 4, a modified view of the rollers, and Fig. 5 a diagram illustrating part of my improvements.

In the manufacture of ordinary linen collars, of the turn-downl or Byron class, it has been usual for some years past to make them of two pieces, a and b, Fig. 3, stitched together, the line on which this junction of the two pieces is made being curved, as shown at x, and the hem presenting a curved ridge, which serves to guide the dresser ofthe collar who turns the portion a over the portion b, the bend being made on the line ofthe ridge. Owing to this arrangement, the collar, when folded and ironed, has a tendency to bend of itselfand to approximate in form to that which it has to assume on being applied to the wearers neck. v

In the above-mentioned patented machine the paper blanks were submitted to the action of steam, which reduced them to such a moist and pliable condition that they could be readily bent and folded without breaking and crumpling the paper. The blanks were the-n pushed toward a pair of rolls by means ot' areciprocating serrated plate, which struck each blank at the part where the collar had to be bent and forced ii between the converging surfaces oll the rolls, the line of the. bend being straight as the rollers and the blade in the said m chinc were straight 5 hence the folded collars were flat and had to be subjected to a moldingl process, in order to impart to them a shape approximating to that which they have subsequently to assume on being applied to the wearers neck, a shape which in the oldfashioned linen collars had been previously acquired by makingl the bend in a curved line.

ln the drawings, A represents the base-plate of my improved apparatus; B, part of the side frames, and U the serrated plate, which tits in guidingslots in the frame and to which a horizontal reciprocating motion is imparted, as in the aforesaid patented machine.

D and D are two rollers turning in the frame and so geared together as to revolve in the direction pointed out by the arrows. rl`he surface of the upper roller, D, is rounded and that of the lower roller concave, the concavity of one roller conforming to the convexity of the other.

The paper blank to be converted into a folded collar is caused to fall with its Vlower edge on a suitable stop or ledge, as described in my aforesaid patent, and While in a vertical position is struck by the serrated edge of the reciprocating-plate, which bends the collar and pushes the bent portion of the same between the converging surfaces of the two rollers which complete the fold.

It will be observed that the plate C is bent to conform to the rollers-that is to say, the upper surface is made concave to suit the concavity of the roller D, and the under surface convex to conform with the convexity of the roller D'. Owing to this arrangement theline ofthe bend in the folded collar must be in a curve corresponding with that of the rollers and blade, and this curve will cause the folded collar to assume the bent form best adapted to that of the wearers neck. At the same time the puckers, which take place in' ordinary collars folded with a straight bend, are obviated.

A result approximating to that described may be arrived at by making the rollers of the modied form represented in Fig. 4. the serrated plate being made to correspond with the rollers. 1, however, prefer the form of rollers represented in Figs. 1 and 2.

It will be observed that the surface of the lower roller, D', is cut away atone point to a limited extent, the portion thus cnt away be ing uppermost when the plate C approaches the limit of its forward movement, so that an opening, y, Fig. 5, is presented between the rollers for receiving the bent edge of the collar. This opening does not extend throughout the length of the rollers, but is such that the collar, as it is seized by therollers, will be held by the same at the opposite ends, while the middle passes freely into the space between the rollers. By this arrangement thc collar more :readily conforms to the shape of the rollers, without being puckered.

Therollersinstead of revolving continuously may be so geared together as to stop for an instant while the collar is being thrust in between them.

I claim as myinvention and desire to secure by Letters Patent- 1. The use of two rollers, one having a concave and the other a convex surface, in combination with a.- reciprocating plate, G, of a form corresponding with that of the rollers, substantially as and for the purpose herein set forth.

2. Cutting awa)7 the circumference of one or both vof the rollers at one point, in the manner and for the purpose described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM E. LOUKWOOD.
