SPECIFICATION forming part of Letters Patent No. 754,649, dated March 15, 1904.-

Applieation filed l'uly 15, 1902. Serial No. 115,642. (No model.)

To aZZ whom it may concerm Be it known that I, ERNST GEssNER, a subject of the Emperor of Germany, and a resident of the city of Aue, Kingdom of Saxony, Empire of Germany, have invented a new and useful Improvement in Cloth-Holding Devices for Textile Machinery.

Heretofore in machines for tentering and drying cloth the mechanism for holding the cloth has generally consisted of two chains each of which was armed with upright pins upon which the selvage edges of the cloth were impaled. At the entrance to the machine the chains were comparatively near together, so that the selvage edges could be conveniently placed upon, the pins by hand. From this entrance-point the chains diverged from each other, so as to stretch the cloth to the requisite width for the drying or tenter- 2O ing operation. Although the attendant could by hand place the edges of the cloth upon the pins, he hadnot suflicient time to impale the cloth upon the pins, and for this purpose pressure-wheels were located along the path of.

5 the chains to produce the impaling before the diverging of the chains commenced to stretch the cloth. The placing and impaling of the cloth upon the pins in this manner was open to serious difiiculties, as well asthe holding of 3 the clothin this'way during the drying or tentering operation.

I have discovered that the impaling of the cloth upon the pins may be automatically accomplished by the pull of the cloth itself, and

one part of my inventionconsists of a device for utilizing this discovery. This device sat isfactorily overcomes the objections attendant upon the old method and also satisfactorily holds the cloth during the drying or tenter- 4 ing operation and also is of such a character as to permit of the ready disimpalement of the cloth from the pins as the'chains converge toward each other at the exit of the cloth from the machine. Other features of my invention will be pointed out in the claims.

In the accompanying drawings, Figure 1 is a cross-section of sufficient of the machine to represent a simple form of my invention. Fig. 2 is a plan of the same. Figs. 3, 5, and

5 7 are cross-sections of sufficient of the machine to represent each a modified and additional form of my invention. Figs. 4:, 6, and

8 are corresponding plan views of the same. Figs. 9 and 10 representa modification. Figs.

11 and 12 are diagrammatic views in elevation and plan of the machine in which my invention is employed.

My device is shown in its simplest form in Figsl and 2, which form will be first described. a I

a a. a a are links of the chain of a drying or tentering machine, every alternate link of which is provided with an opening A to receive the sprockets of the wheels by which the chain is supported and driven. The links 5 of this chain have tongues j and ,clevis forming pivots which are so arranged that the connecting-pins I I I are alternately at right angles with each other. The chain is supported and guided from below by guide- 7 bar D and is guided in the desired vertical plane by the tongue OZ extending downward from the guide-bar D into a groove formed between the outeredge of each, alternate link a a and a flange C, fixed to such outer edge.

The mechanism which I will next describe is duplicated on each of the alternate links a (f, &c., of the chain, a description of one answering for all.

B is a flange extending horizontally from and fixed to the inner side of the link a and havinga foot-piece b to rest upon the guidebar D; I

B is a cloth-plate resting and secured in any suitable manner upon the flange B at such 5 an elevation that its upper surface is in substantially the same plane as the axes of the pins I and 1 This cloth-plate B has diverging sides, so that its greatest length is nearly equal to the distance between the centers of the pins I I The efiect is that the series of cloth-plates B B B form a nearlycont'inuous cloth-bearing surface and enable the se-. ries of pins upon which the cloth is impaled to be substantially continuous and equidistant from each other.

E is an overhanging arm fixed to the inner edge of the link a and extending inwardly toward the opposite chain farther than the cloth-plate B. The extremity of this over- I00 hanging arm is provided with a cross-piece E, in which is journaled the pin E Fixed to the ends of this pin are the downwardly and outwardly inclined arms ff, which carry at their extremities the cross-bar F, to which is secured the pin-plate Gr, carrying the series of pins G. The series of pins carried by each link a is sufiiciently extended to form a substantially continuous series with the adjacent series of pins supported on other links.

H H are two fingers or feelers fixed to the bar F, which are capable of oscillating arou nd the center E through the slots 5 12 in the cloth-plate.

f is a finger fixed by a yoke f to the arms ff and extending upwardly above the overhanging arm. e is a stop on the overhanging arm, whereby the motion of the finger f is limited.

6 b, &c., are a series of slots or notches in the edge of the cloth-plate through which the series of pins G may oscillate around the center of E The operation is as follows: At the entrance to the machine, where the chains are comparatively near together, the selvage edge of the cloth goes onto the cloth-plate in the position shown at J, Fig. 1. The presence of the cloth in this position supports the feeler H, and consequently the series of pins G, in the position shown in full lines in Fig. 1. As the cloth and chain advance from the entrance toward the drying or tentering chamber the recession of the chains from each other causes the edges of the cloth to slip toward the inner edge of the cloth-plate until the cloth edge slips from under the feelers H and permits the feelers to drop into the slots 6 b and permits the scries of pins G to rest upon the surface of the cloth. In this position the edge of the cloth is still supported from below by the clothplate B and the series of pins rests on top of it. As now the recession of the chains from each other is continued the opposition of the cloth to being stretched will pull the edge of the cloth still farther inward over that portion of the cloth-plate containing the series of slots 6. This movement, however, carries with it the series of pins resting upon the cloth, which, moving around the center of E pass down through the slots '6, and therefore are compelled by the pull of the cloth itself to thoroughly impale the cloth. As the inward movement of the edge of the cloth proceeds still farther, owing to the further divergence of the chains, the edge of the cloth will fall off of the inner edge of the cloth-plate by the time that the series of pins reaches the position shown in dotted lines in Fig. 1, so that by the time the chains have reached their greatest distance apart and begin to run parallel with each other the edge of the cloth will be held exclusively upon the series of pins G. The stop 0 holds the series of pins at each edge of the cloth in the outwardly inclined or diverging position, (shown in dotted lines in Fig. 1,) so that as the cloth passes through the drying or tentering chamber the cloth tends to hold itself securely upon the series of pins by its own tendency to shrink or oppose the stretching. As soon as the cloth has passed out of the drying or tentering chamber and the chains begin to converge toward each other the slack thereby produced crosswise of the cloth will enable it to be readily stripped by the pull of any suitable draft-roll from the series of pins at each edge. Thereafter any suitable device engaging the arm f' returns the parts to the position shown in full lines of Fig. 1 and retains them there, ready to receive a new portion of the cloth at the entrance of the machine. During all of this operation the cloth is protected from being spotted by oil or grease by the location of the guiding-tongue d and its engaging groove exclusively on the opposite side of the chain from the. cloth. This location of said guide also enables the wearing-surface to be increased.

In the modification shown in Figs. 3 and 4 the parts already referred to are, with the exceptions below noted, substantially as already described; but in addition thereto means is provided for straightening out the list-curl of the cloth, if such occur. This consists of an uncurling-plate K, which is pivotally mounted upon the pin E. It rests upon a stop k fixed to the overhanging arm, and is therefore capable of being raised above but not lowered below the position shown in Fig. 3, where the distance between its lower edge and the upper face of the cloth-plate is just sufficient to accommodate the thickness of the cloth. This stop can be made adjustable, as byaset-screw, if desired. As the edge of the cloth is, as before described, drawn inwardly over the clothplate any curled list, such as that shown in Fig. 3,will be straightened out by the plate K pre-' paratory to being impaled by the series of pins, The plate K is preferably held in the position shown in Fig. 3, inclined to the surface of the cloth. In Fig. 3 the function which in Fig. 1 was performed by the stop a is performed by the engagement between the projection f on the arm f with the projection on the uncurling-plate K, as shown by dotted lines in Fig. 3. To insure straightening of curled lists if they happen to turn under, I form a recess or groove L, the edge thereof which engages the curl in the cloth lying beneath the corresponding edge of the uncurling-plate K,

IIO

the edges of both the uncurling-plate K and might be used; but a clear open space provides room for the roll to drop down in better position to be uncurled than if there were ribs to the chain.

hold portions thereof at the level of the cloth plate. I

The construction shown in Figs. 5 and 6 is substantially like that shown in Figs. '3 and i, the principal difference being that the uncurling-plate K is hinged on special pivots N,

' carried by the arm E nearer to the chain than the pivot E Slots 7c in the plate K accommodate the feelers H. The plate K is raised by engagement with the feelers H. In this construction the arm f is connected with the arms f and f.

In Figs. 7 and 8 the construction shown differs from that shown in Figs. 5 and 6 in having the smoothing or uncurling plate K pro- Vided with arms K pivoted at N entirely outside of the cloth or between the cloth and the chain. The ends of the feelers H extend be neath the plate K and lift it when the pinplate is swung inward and upward or toward InFigs. 7, 8, 9, and the flange B of the other figures is replaced by arms M, which are shown as directly beneath the arms E, although this is not an essential position.

In Figs. 9 and 10 the feeler-arm H is an extension of the arm f, and the feeler H is made I I of such shape that it acts as the smoothing or the chain is led to the point of attachment, are

on separate studs or shafts set at an angle to each other, so that the planes of the wheels g g converge and'cause the chains to converge as they rise from below to the point of attachment. h h are the trackways, the general trends of which diverge to the dryingmachine proper and thence extend parallel back and forth through the machine. From the wheels 2', at which the cloth is detached, each chain extends loosely, as shown, to its entering wheel.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a cloth-holding device for textile machinery, in combination, a cloth-support, a series of pins and means whereby said pins are forced to impale said cloth by the pull of the cloth on said pins.
