' MACHINE FOR MAKING SELVAG ES ON FABRICS.

SPECIFICATION forming part of Letters Patent No. 567,779, dated September 15, 1896. Applic tion fil d November 9,1895. Serial No. 568,425. (No model.)

To all whom it may concern:

Be it known that I, THOMAS W. BRACHER,

. a citizen of the United States of America, re-

siding in the city, county, and State of New York, have invented certain new and useful Improvements in Machines for Making Selvages on Fabrics, of which the following is a specification.

The purpose of my machine is to shear apart textile fabrics and secure the severed edges with adhesive material. This it does by passing the work between rolls, one of which has a knife-edge, and applying the adhesive material to the severed edges at the rolls as the fabric is passing between them. Afine cord or thread moistened with adhesive material is conducted between the cuttingrolls with the fabric. The pressure of the rolls squeezes the adhesive material out of the cord into the severed edges of the fabric and the adhesive material on setting forms a selvage. Means are also provided for folding over the severed edges and applying adhesive material in the angles of the foldedover edges to cement them down. In this way I can produce a selvage edge around pieces of-fabric of straight or sinuous outline. This selvage edge, however, has an important specific application in the production of ribbons of varying width, such as are, forexample, desirable for scarfs and hat-bindings. I make these by cutting apart a wide ribbon along a wavy or other line to give the desired varia tion in width to the severed parts. For the automatic production of these the machine is provided with a trough, which guides the fabric to the cutting-rolls and which,by means of cams, is given a combined lateral and angular movement, so that the fabric will be fed to the rolls in such a way that it will be sheared apart along the desired curve. The mechanism by which these results are obtained I believe to be new, as hereinafter described and claimed.

In the accompanying two sheets of drawings, which form a part of this specification, Figure l is a plan view of my invention. Fig. 2 is an end view thereof, and Fig. 3 is a side view of the rolls by which the fabric is severed and the adhesive material applied. Fig. 4: is a plan view in which thespindles bearing the cutting-rolls and the rod over which the work is delivered are removed. Fig.

5 is a side view of the machine.

The severing of the fabric is effected by means of two rolls, the upper of which is brought to a single edge and is the knife-roll K. Below it is the grooved roll G, which is brought to two sharp edges. These rolls are carried by two spindles Q Q, which are geared together by gears U U. The lower of these spindles has a gear N, which meshes with a pinion O 011 a stud with a pulley-Wheel IV, by which the machine is driven. A fine cord or thread G passes through a box S, which contains adhesive material, as, for example, shellac. From this it passes half-Way around the grooved roll and under the fabric. The knife-r011 acts as a separating device and cuts through the fabric and into the underlying cord in the groove of the grooved roll. The cord is preferably of greater resistance than the fabric to be severed and being of yielding substance prevents the dulling of the knife-edge and insures the complete severing of the fabric. At the same time the pressure squeezes the shellac out of the cord and into the edges of the fabric as they are cut. The

cord thus serves a double function-first, as a traveling carrier to transfer the adhesive material to the cut edges while they are tightly held between the two rolls, and, second, as a buffer on the opposite side of the fabric from the knife, into which the knifeedge of one of the rolls presses on cutting through the fabric. There is also a second box for shellac, R, in which is a gum-roll r, by which the shellac is transferred to the flanges of the grooved roll.

011 the spindle with the knife-roll and on each side of the knife-roll are. disks D D, which are pressed toward the rolls by springs P P. These disks are loose on the knife-roll spindle, so that they can tilt slightly, but they revolve with it. On the side where the two rolls come together the disks overlap the grooved roll and serve to fold the fabric over its sharp edges. The fabric having thus been folded and at the same time out it is carried around with the knife-roll and the disks for nearly three-fourths of a revolution, and the folded edges of the two severed parts sink into the two grooves formed by the meeting of the disks and knife-ro1l. The edges of the fabric are thus pinched down and held while the shellac sets. On leaving the knife-roll and the disks the severed parts are delivered over a rod H.

It is not necessary to the carrying out of my invention always to apply the shellac in both the Ways which have been described, for under some conditions either may be sufficient, and the application of the shellac may, if desired, be made by means of a gum-roll directly to the knife-roll or to the groove of the grooved roll and the use of a moistened cord avoided. There is an advantage, however, in cutting against a moistened cord that the knife-roll does not dull so readily, since it is not necessary to set it so close to the grooved roll in order to insure the complete severing of the fabric.

As a binding for hat-brims I find that it is desirable to use a ribbon which has a width of an inch at the sides of the hat and a width of half an inch at the front and back. Taking the circumference of a hat-brim at thirtyfour inches it will be seen that such a ribbon should have two narrow and two wide places in that length. This is What my machine, as shown, is designed to make when constructed of such proportions that the rolls will be one inch in diameter. The work is fed to the machine as a straight ribbon having a uniform width of one and a half inches. This is sheared apart along an undulating or sinuous line, the waves of which repeat every seventeen inches, and two ribbons, as above described, are simultaneously produced.

Automatic means are provided for guiding the work, so that it will be sheared in the way that has been indicated. This is done by cams which reciprocate transversely the guide or trough T, through which the work passes to the cutting-rolls. The trough is supportedat the front by a bracket which is jointed to a rod E, that slides through a hole in the frame ofthe machine below the spindles of the cutting rolls. The rod is reciprocated through a lever L by a cam A. A second cam B is located under the guide for the work and operates upon it directly. These cams are revolved through suitable gearing, consisting of worm-Wheels I and J, a worm -shaft F, and gearing M and N, so that each will turn through one revolution to a peripheral travel of thirty-four inches by the rolls. By changing the gearing the machine can readily be altered so as to produce other lengths.

In order to produce two undulations to a revolution of the cams they are each provided with two lobes. The cams are so shaped and set with respect to each other that the highest points of one and the lowest points of the other will bear simultaneously against their respective rolls. Then one of the lowest points of the cam A and one of the highest points of the cam 13 are against their respective cam-rolls, the guide will be in its extreme position to the right. With the converse positions of the cams the guide will be in its extreme left position. In both positions the guide is parallel to the direction of cutting, since at these points the line along which the ribbon is sheared lies in the direction of the ribbon; but while shifting the guide from one side to the other it is necessary to tilt slightly to an angular position in order to keep the line of shear in the direction of cutting. This is effected by so shaping the cam B that the part of the guide acted upon by it will move laterally in advance of the part acted on by the cam A.

The adhesive material employed as described is a finishing substance and is a liquid or semiliquid substance.
