TEXTlLE-CLAM P.

SPECIFICATION forming part of Letters Patent No. 633,630, dated September 26,1899.

Application filed November 8, 1898, Serial No. 696,827. (No model.)

To all whom it may (307L667IL;

Be it known that I, CHARLES L. WEICHELT, a subject of the Emperor of Germany, having resided in the United States one year last past and having declared my intention of becoming a citizen thereof, residing in the city and county of Philadelphia, State of Pennsylvania, haveinvented a new and useful Improvement in Textile-Clamps, which improvement is fully set forth in the following speci fication and accompanying drawings. 7

My invention consists of a textile-clamp employed in a fabric stitching or tentering machine embodying a table, a movable jaw, a swinging arm, bearings for said jaw and arm, a jaw pivot-ally mounted on said arm and having a fork thereon, and an arm fixed to said jaw adapted to be engaged by one member of said fork to elevate the jaw and by the other member to assist in depressing the same, it also embodying a spring connected with said jaw to further assist in the descent of the latter, and a shoe pivoted to said arm, adapted to enter an opening in the table, and a heel fixed to said arm and freely resting upon said table, as will be hereinafter more fully described, and pointed out in the claims.

Figure 1 represents a front view ofa textileclamp embodying my invention. Figs. 2 and 3 represent a section thereof on line .93 50, Fig. 1, the parts being in different positions. Fig. i represents a top or plan view thereof.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a traveler or link which is mounted on or forms part of an endless belt, as usual in clamps of the present class. Secured to said traveler is the table B, from which rise the arms D of the frame of the clamp, whose upper ends form the bearings for the rock-shaft E, to which is secured the jaw F, which depends therefrom over the table 13 and has the handle or lever G secured thereto and so disposed that the machine to which the clamp is applied has a movable member thereof adapted to engage said lever, so as to raise said jaw whenfabric is to be placed on said table and afterward start the lowering of said jaw when the fabric is to be engaged, as will be hereinafter more fully-described.

Mounted on the shaft E is the rearwardlyprojecting rising-and-falling arm H, and secured to the jaw F below said arm II is the arm J, which also projects rearward, said arm H having the heel K depending therefrom and carrying on its lower limb H the shaft L, on which is mounted the shoe M, below which is the opening N in the table B. The upper end of said shoe is provided with the horns P and Q, between which the end of the arm J is adapted to enter, as shown in Fig. 3, while the horn Q is adapted to hold said arm in elevated position, as shown in Fig. 1, when the jaw F is controlled, thrown back from the front portion of the table, and held above the same, as also shown in said Fig. 1.

R designates a spring which bears against the jaw F, as at S, and some fixed member, (in the present case the arms D,) so as to exert forward pressure on said jaw, a portion of said spring being coiled on the shaftE for con venience, as shown'in the figures.

The operation is as follows: The lever G is moved forwardly or to the left, as shown dotted in Fig. 3, when the jaw, the shoe, and connected parts are raised from the table. The fabric is now placed on the table, and the lever is then moved to the right, as shown in Fig. 2, when the shoe M rests on the fabric and the latter covers the opening N and controls the shoe, and consequently the jaw, against descent, it being noticed that the fabric is relieved of the weight of some of the parts above the same, owing to the heel K resting on the table B, the position of the several members heing shown in said Fig. 2. The fabric is now drawn in the direction of the arrow, when as it clears the shoe the latter is permitted to drop into the opening N, when the parts connected with the shoe also drop, and the jaw swings outwardly overthe table, while the fabric draws the lower edge of said jaw downwardly against the table, as a bite, assisted by the weight of the parts and the pressure of the spring R against said jaw, the power of said spring being effective should the bearings of the part be clogged by pieces of yarn or material, dust, &c., thus most firmly clamping the fabric between the jaw and table and controlling it against further outward motion, as will be most apparent on inspection of Fig. 3. Then the work is accomplished, the lever is again moved in the ICO direction to the left, when the jaw is raised and the parts reset in elevated position, releasing the fabric and permitting it to be removed and admitting of the application of a fresh length or piece of fabric to the table preparatory to the next advance of the jaw and the action of the same similar to that hereinbefore set forth.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In atextile clamp, a table, a movable jaw, a swinging arm, bearings for said jaw and arm, a shoe pivotally mounted on said arm and having a fork thereon, and an arm fixed to said jaw adapted to be engaged by one of the members of said fork to elevate the jaw and by the other member to assistin depressing the same.

2. In a textile-clamp, a table, a movable jaw, a swinging arm, bearings for said jaw and arm, a shoe pivotally mounted on said arm, and having a fork thereon, an arm fixed to said jaw adapted to be engaged by one of the members of said fork to elevate the jaw and bythe other member to assist in depressing the same, and a spring connected with said jaw and fixed member to further assist the descent of said jaw.

3. In a textile-clamp, a jaw, a table, a swinging arm independent of said jaw, bearings for said jaw and arm, a shoe pivotally mounted on said arm, a heel on said arm and a fork on said jaw, in combination with an arm fixed to said jaw, and entering the members of said fork, one member being adapted to bear upwardly against said arm to elevate it and the other member being adapted to bear downwardly on said arm to depress and lower said jaw.

4. In a textile-clamp, a jaw, a table, a swinging arm independent of said jaw, bearings for said jaw and arm, ashoe pivotally mounted on said arm, a heel on said arm and a fork on said j aw,'in combination with an arm fixed to said jaw-and entering the members of said fork and one member being adapted to bear upwardly against said arm to elevate it and the other member being adapted to bear downwardly on said arm to depress and lower said jaw, and a spring connected with said jaw and a fixed member to further assist the descent of said jaw.

5. In ateXtile-clamp, ajaw, a swinging arm independent thereof, bearings for said jaw and arm, and a table, in combination with a shoe pivoted to said arm and adapted to enter an opening in said table, and a heel fixed to said arm and adapted to freely rest upon said table.
