IMPROVEMENT IN' MACHINES OR .PPLYING- REINFORCING-PATCHBS TO BUTTON- 4HOLES OF COLLARS.

The Schedule referred to inpthese'Letl-.ers Patent and making part of the'same.

To all whom it ma/y concer-n Be it known that I, H. F. CARY, of Boston, in the county of Suffolk, and State of Massachusetts, have invented au Improvement in the Manufacture of Paper Collars; and l do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my inventionsuiicient to enable those skilled in the art to practise it.

In the use of paper collars, as articles of wearing or dress-apparel, one obstacle to their success or endurance is the tendency of the button-holes' to tear out, the paper not having strength, iu itself, sufficient to resist the strain brought at the angles of the buttonholes, without giving way.

To obviate this dfculty, the paper is sometimes strengthened at those surfaces, or portions of surface, Where the button-holes are or 'are to be cut, by cementing thereto patches of cloth or paper; and my invention relates to the manner of applying these reinforcing-patches.

Before rny invention, it was generally the practice to apply these patches by hand, patch by patch, and, besides the time consumed by such process, itwas difficult to always place the patches just in proper positionfor surrounding the holes to becut; and my invention consists, primarily, inthe employment of ribbons, each having a'cement-applied surface, these ribbons travelling over. the collar-paper, (before it is punched into collars or collarblanks,) at the centre and near the opposite edges of the paper, or in lines Where the button-holes are to be cut, so that, by the action of a punch and die to cut out the patch, and a follower to press the patch down upon the surface of the paper, the patches shall be cemented to the paper in proper position, the cement-applied surface of the ribbons being moistened before the dies operate, so that the patches shall adhere to the paper.

The drawings represent a machine for cutting out and applying the button-hole reinforcing-patches, in accordance with my invention, the mechanism being shown in connection with the mechanism for stamping out the collar-blanks and the button-holes.

A shows the machine in side elevation.

B is an end view of the same.

C shows a portion of the collar-paper, with the patches aed thereto.

a denotes the frame, a't one end of which are the ordinary button-hole punches, b, and collar or collar blank punches, c. At the opposite'eud of this frame a loose shaft, d, is mounted in suitable bearings, this shaft carrying three-drums or spools, e, having wound upon them ribbons, j, from which are cut the buttonhole patches, each ribbon being preferably made of cloth, and having one dry cement-applied or gummed surface.

,Under the shaft. d is a trough, g, for holding water,

Vand over the trough is a loose shaft, h, cairying three allowing-rolls, i, the peripheries of which dip into the water, so that their surfaces are kept wet by rotation ofthe shaft. On the opposite sides of the shaft h are guide-rolls, k Z, and the ribbon from each spool e passes under the front roll, 7s, over one of the wallowing-rolls i, underneath the roll l, its cement-applied surface being thereby brought into contact with the wet surface of the roll i, to make such surface adhesive.

j denotes the collar-paper, passing from a suitable roll or paper-cylinder, up and over three bed-plates or flat disks, m, and thence over a platform, n, to the button-hole and blank-cutting mechanism.

o denotes a vertically-reciprocating carriage, sliding between ways, p, and jointed to pitmen, g, hung upon crank-pins o', on the ends of a crank-shaft, s. To this carriage are fixed'three punches, t, arranged directly over the bed-plates m, and working through die-plates u, between the lower surface of which and the bedplates m, the collar-paper passes, as seen at A, while beneath each punch, and between the upper surface of each die-plate and the under surface of the die-head or stock c, one of the patch-ribbons f passes, as seen at A.

Each die-plate has a die-matrix or female die corresponding to the end of the punch above it, and to the form which the button-hole reinforcing-patch is to have, and at each descent' of the carriage o, each punch t is carriedthrough the die beneath it, cutting a patch from the ribbon in its descent, and carrying such patch down against the collar-paper beneath it, forcing the patch and paper against the bed-plate, and thereby causing the cement-applied and moistened patch to adhere to the paper, as will be readily understood.

The three punches t are arranged at distances apart corresponding to the positions at which the end `and centre button-holes are to be formed, and each punch is preferably made oblong or oval, and so arranged that the end patches are applied lengthwise of 4the collar- .blank to be cut, and the centre one crosswise, as shown at C, so as to correspond to the oblong form of each button-hole.

n Each patch-ribbon j, after passing over the bed-plate my, (that is to say, after having the patch cut from it,) passes under a guide-roll, x, thence up between a pair of draw-rolls, y, and thence around a waste-roll, z, as seen at A.

The roll is connected to ahd driven from the crank- 'shaft s, by a band, a2, passing aroundv pulleys on the shaft and roll,l this band being, however, suiiiciently' Qloose to slip on the pulley on roll z if the ribbon is held back by the draw-rolls y.

The rollsy have an intermittent positive movement imparted to them, so that they shall cease to draw the ribbon while the patch-cutting punches are descending. this intermittent motion being derived as follows;

vthe periphery of a cam, i2, on the crank-shaft s.

On the end of the lower shaft, i is a gear-pinion, b2, which meshes into and Yis driven by a gear-wheel, c, mounted ona short shaft, (l2, projecting from the frame A. This gear c2 canies a series of pins, e2, into which engages, at proper times, a sliding latch or hook, f?. The shank of this hook slides vertically through a suitable guide or guides, and is connected at its lower end, by a spring, gz, with the frame a, this spring holding the hook-shank, or an arm, h2, thereof, up against As the shaft s, in its ascent, carries up the punches At, the cam i? presses down the hook, which, being hooked upon one of the pins, e2, will thereby impart rotative movement to the lower draw-roll, which'will draw forward the patch-ribbon, the roll z turning at the same time, and winding the waste-ribbon upon it.

When the punches descend, however, thehook-shank will be carried up by the spring gi, and an incline, t2, will cause the hook to slip out by the next pin above it, passing which, it will slip in over such pin.

rI he collar-paper, with the patches cemented upon its upper slu'face, is fed along by suitable mechanism, and passes forward to the operation of the button-hole punches b and the punches c, which cut out the collarblank.

It willithus be seen that the collars are automatically provided with button-holes having reinforced edges, and that these patches are applied while the paper is in sheet-form, or before the button-holes or collar-blanks are cutout.

The mechanism may, of course, be varied, but I consider that a mechanism, substantially as shown, is the best to use. v

As the centre patches cover less space, in the direction of the length of the' collar-papenthan the side ones, provision may be. made for taking up the side strips or waste ribbon, after the patches are out, a little faster than the centre strip, and this provision I have made in a machine now in use.

.Instead of cloth ribbons for the patches, paper strips may be employed, but I consider the cloth preferable.

I claim the process herein described, of applying to paper,'before or after its conversion int-o collars, reinforcing button-hole patches, automatically cut from gummed' stlips, continuously moistened in their pas? sage through the machine, substantially as described.

I also claim, in a machine for applying strengthening-patches to button-holes of collars, a trough andguides, for moi'stening the cement-applied surface of the ribbon.
