MACHINE-FOR CRIMPINGAND PREPARING ELASTIC FABRIC.

SPECIFICATION forming part of Letters Patent No. 315,842, dated April 14, 1885.

I Application filed December i2, 1883. (No model.)

:To cZZ whom itmwy concern:

Be it known that I, GUSTAV SOHILLING, of Detroit, in the county of Vayne and State of Michigan, have invented a new and useful, Improvement in Machines forlir'eparing and Crimping Elastic Fabric; and I'hereby declare; the following to be a full, clear, and exact de-? scription of my invention, that will enable. others skilled in the art to which it appertainsf to make and use the same, reference being had: to the accompanying drawings. 1

Figure 1 represents a portion of my ma-; chine, and Fig. 2 represents the remainder.; Fig. 3 is a side view of the part 0, showingi the slots by which it is' attached to the part{ B. Fig. i is a perspective view of the 'machine, the jaws being represented as closed, and the removable clamp shown in position. in dotted lines. I

A represents the fixed and B represents the movable jaw of a vise, the motion of which is controlled by a screw or any equivalent mech anism. Along the upper side of each of these jaws is a line of indentations, either continuous or at intervals, according to the pattern desired to be imparted to the crimped fabric.

K and K are two bars, hinged at H and H to the ends of the jaws, so that K can be turned on the hinge H into contact with the upper surface of A over the line of indentati ons therein, and K can be turned in the same ni anner into contact with the upper surface 0 B.

On the inner surface of B, I place two knobs or hooks to hold and support the removable block D. C, also removable from A, is supported upon it in the same manner.

At the end of A,opposite to the hinge H, I construct a spring-catch to hold the bar K firmly in contact with A when it has been turned down upon it. A similar catch upon the end of B holds K when it has been turned upon the hinge H into contact with the line of dents along B. I

(l, D, and R represent the parts of a removable clamp, the parts of which are constructed as follows: The main portion or body of O has a width equal to one-half that which it is desired to have the fabric after it is crimped. On the side which comes against the jawA of the vise I afiix, permanently, a

plate of metal covering the side of C, and extending above its upper surface. This projecting portion is indented to correspond with the indentations on the upper surface of the jaw B of the vise, and slots are out into the plate,

as shown at c a in Fig. 3, to fitover the knobs or hooks upon the inner surface of the jaw of the vise, care being taken in making these slots to have the indentations in the upper edge of the plate and in the upper edge of the jaw of the vise to correspond accurately when the parts 0 D are placed in position upon the knobs or hooks. The ends of the parts G D preferably extend a short distance beyond the plate affixed to the side of each, to enable the clasp upon Rto embrace and hold the two firmly together. 0 and D are similarly constructed, and are similarly attached to the jaws, except that one is fitted for attachment to the right side and the other to the left side.

The binder R is made of a single piece to correspond with the shape of the united upper faces of O and D when the same are brought 7 5 into conjunction. At either end it has a hinged socketed clasp, so that when the binder is placed over the piecesG D, the latter being brought into conjunction and the clasps turned down, the ends 6 e are embraced by the socket t, and the ends f f are inserted in the socket u. The three pieces being firmly held together, they may be removed from between the jaws of the vise by lifting them from the sustaining hooks or knobs.

In employing my said invention I attach the pieces 0 D upon A and B, respectively, by slipping the slots 0 a down upon the knobs or hooks on the inner side of A and B. I then place the fabric, prepared in the usual manner, by quilting or stitching it so as to form sacks or pockets through which wires are thrust, and lay itbetween the indented projections upon 0 and D, placing the ends of the wires in the indentations of both A and B. The clamps K K are then turned on the hinges H H until the ends are caught under the spring-catches. The inner edges of G D are brought together by closing the jaws of the vise containing them, and the fabric is thus crimped upon the wires. I now place the binder shown in Fig. 1 upon the fabric, and turn the socketed claspst a are to be kept parallel.

down over the ends e e ff. The fabric is now closely confined between the faces of R on the upper side and O and D on the under side,

' and prevented from expanding laterally by the in" a group, leaving intervals between the groups from one-half (i) inch to one and onehalf inch. I also arrange the indentations so that the groups of wires shall not lie entirely parallel with each other across the fab ric, though the wires of each separate group This arrangement causes the portion of the fabric between the groups of wires to be crimped much more evenly and in a more attractive manner than when the wires are laid entirely parallel. It also tends to prevent the crimped fabric from flattening down. v

I am aware that fabric has been shirred by the use of a clamp or machine composed of a stationary clamp in combination with a movable clamp, within which the two ends of the wires thrust through the fabric are received, and a removable clamp, into which the fabric is crimped by the moving up of a movable holder, and that in such machine the removable clamp was intended to hold the fabric from lateralexpansion and the wires in proper position by means of blocks of elastic material arranged at suitable distance apart to receive the pocket-sections between them, and having serrated plates on the edges of the inner faces. In such machines, however, the elasticblocks compressed the fabric so as to injure its appearance, and there being only a single part to the clamp below the fabric, the fabric in crimping was forced over the serrations. which frequently caught the fabric and tore it or rendered the crimping uneven, and frequently, when removed, the serrations did not suffice to confine the fabric and prevent a lateral expansion. These difficulties are entirely' obviatedin my machine.

Having thus described my invention, what I claim as new, and desire to have secured by Letters Patent, is- I 1. In a machine for preparing elastic fabric, in combination with the fixed and movable clamps attached to and forming the jaws of a vise, the compound clamp composed of two parts below the fabric and a third above the fabric, the latter having clasps affixed to it for binding all three together and firmly hold- .ing the crimped fabric between the three, substantially as described.

2. In a machine for preparing elastic fabric, the compound clamp composed of two parts indented along their outer'upper edge, within whichdents the two ends of the wires thrust through the fabric are received, and having their upper face within the dents together equal to the width of the shirred fabric, and a third binding part having aflixed to it clasps for binding all three parts firmly together andfirmly holding the crimped fabric between the three, substantially as described.

3. In combination with a fixed and movable clamp, within which the two ends of the wires thrust through the fabric are received, the two removable parts of the compound clamp herein described, each of which is adapted to be attached or detached readily from said fixed and movable clamps, substantially as and for the purpose described.
