IMPROVEMENT IN MACHINES FOR FOLDING PAPER COLLARS.

' Specification forming part of Letters Patent N0. 59. 13/1. dated October '23, 1866.

To all whom it may concern:

Be it known that I, CHARLES E. MOORE, of Roxbury, in the county of Norfolk and State of Massachusetts, have invented a new and useful Machine for Folding Paper Collars; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference heilig had to the accompanying drawings, forming a part of this specification, in which- Figurel is a top view, and Figs. 2 and 3 are side elevations.

Like parts are indicated by the same letters in all the drawings.

The purpose of my invention is to fold or turn over paper collars on a curve line with the greatest accuracy and dispatch and its nature consists in the employment of an angular groove or channel ofthe same curvature as the line on which the collar is to be folded or turned over, and a former or die, so shaped and arranged as to fit iuto the said groove or channel, and force a-collar into the same, and thereby turn it over on the required curve.

My invention further consists in the employment 'of rollers, arranged each side of the center of the said groove to grasp the collar, (while it is under the formingdie,) press the two parts together, and drive it laterally from the groove into any suitable receptacle, the die being slightly elevated, so as to allow Vvthe collar to slide freely under it after it has been bent thereby iuto the requisite curve.

To enable others skilled in the art to make and use my invention, I will now proceed to describe the construction and operation of the same.

A, B, C, and D constitute the frame of the machine, of wood or metal. E is the drivingshaft, turning in suitable bearings in the arms fu c each side of the frame, the said shaft being driven by the crank t, by hand, or by power, in any obvious manner. F is a pinion fa-st to the shaft H, and shaped as clearly shown in Figs. 2 and 3. K is a bent lever, which vibrates on the trunnions L in suitable boxes h h attached to the frame A. The lower end of this lever K is provided with a friction-wheel, J', which turns on a pin, J, projecting from the side of the same, and rides on the cam I, giving the required movements to the lever K. M is aflat bar attached to the front end of the lever K, at right angles to the same, as shown in the drawings. l Attached to the bottom of the bar M by means of screws g, or in any other obvious manner, is the die or former N, of wood or metal, the under side of which is brought to a point, as represented in Figs. 2 and 3, while its general shape or curve is intended to be the same as that on which the collars are to be folded or turned over.

O is the block or table, of wood or metal, fast to the top of the frame A, and provided with an angular groove or channel, I?, the end of which is seen in Figs. 2 and 3, and the top in Fig. 1, being'of the same curvature as that ofthe die N and the line ou which the collars are to be folded.

Q and R are wheels fast to the ends of thev shafts T and S, and arranged in slots iu the table O each side of the center of the groove P, and extending from the bottom of the same nearly up to the top, as represented in the drawings. 4A/rotary motion is communicated to these vwheels by means of a belt, V, running from a pulley, U, on the shaft E to the pulley W on the shaft X, the latter being provided with a bevel-pinion, Y, which aetuates" the bevel-pinion Z on the shaft T, a being a gearwheel on the shaft S, actuated by the gearwheel w, which is cast in one piece with the bevel-gear Z.

The upper end of the shaft S runs ina box, l, which slides under the table O, as represented bythe dotted lines in the drawings. This box l is connected by the link 7c and pivots m and a with the bent lever d, which vibrates on the fulcrum e. The lower end of the lever d is provided with a friction-wheel, t', which runs on the periphery of the cam b, the latter being so shaped and arranged as to cause the wheel R to approach the wheel Q, as shown in Fig. 2, or recede from it, as shown in Fig. 3. ff are small pins projecting above the table O back of the groove P, to operate as guides for placing the collar to be folded in the re quired position.

The operation of the machine is as follows: The collar, bein g cut out the proper size and shape, arid inished with the exception of being folded, is placed upon the table O so that its convex side shall rest against the guidepins ff, torming-dic N being raised above the table and the roller R withdrawn from the roller Q, as represented in Fi g. 3. If the driving-shaft E is now rotated by hand or power, the die N, actuated by the cam I, will be brought down upon the collar and forceitinto the bottom of the groove or channel P, thereby folding or turning the collar in a curved line each side ot' the edge of the die, which'it does, owingto the shape of the die and channel, without wrinkling or pucliering the paper. The cam I from this point is made a little smaller, so as to allow the die to rise the sixteenth ot' an inch or so above the collar, in order that the latter may slide with freedom in the channel. At this point also the wheelR is, by means of the cam b, forced into the position shown in Figs. l and 2, so as to nip the turnedover portion of the collar between them and draw the collar alongfrom under the die through the groove, and deliver it one side ot' the machine, in the direction of the arrows, into any suitable receptacle, while at the saine time they complete the operation of turning and pressing the one part of the collar upon the other.

My machine is capable of folding collars as rapidly as an attendant can place them (one at a time) in the proper position on the table under the die, and performs the operation with the greatest uniformity and neatness.

Having thus described the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent,

l. Folding collars by means of the angular groove P and die N, substantially as described.

2. The rollers R and Q, arranged and operating in combination with the groove P and die N, substantially as and for the purpose described.
