CLAMP FOR FABRIC-MAKING MACHINES.

SPECIFICATION formingpart of Letters Patent No. 640,824, dated January 9, 1900.

Application filed February 17, 1899.

Be it known that I, JOHN 'SOMMER, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Clamps for Fabric-Makin g Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in clamps revoluble with relation to the machine with which they are connected, by means of which a clamp is provided, being simple in construction and very efiective for the purpose designed.

More particularly, my invention relates to a revoluble clamp designed to be used in connection with a fabric-making machine purposed through suitable mechanism provided upon its surface to alternately through a series of jaws engage and release the strands of a fabric being woven upon the machine with which the clamp is connected for the purpose of drawing out the strands of the fabric being woven.

My invention consists, essentially, of a cylindrically-form ed roller suitably constructed for lightness and cheapness and for durability, purposed to be mounted upon the framework of a fabric-making machine in suitable manner to provide for its rotation by the proper connection with suitable mechanism provided in the machine for turning it at the proper times and the proper distances.

My invention also consists, essentially, of a row or rows of jaws suitably mounted upon the surface of a roller or cylinder and of suitable mechanism for actuating the said jaws in such a manner as to cause a uniform pressure to be brought to bear simultaneously by the jaws upon the strands of the wire fabric and to cause the alternating engagement and releasing of the strands by a series of the rows of jaws upon the fabric being woven upon the machine, and of certain other details of construction hereinafter more particularly described, and pointed out in the drawings.

That my invention may be more fully un- Serial N0- 705,8ZZ. (No model.)

derstood, reference is had to the accompany ing drawings, in which-- Figure 1 is a plan elevation of the clamp. Fig. 2 is an end view of the clamp,showing the manner of engaging the strands of the wire fabric by the jaws upon the clamp. Fig. 3 is an enlarged elevation of Fig. 1, showing the mountings removed. Fig. 4 is a vertical longitudinal section showing the detail construction of the clamp. Figs. 5 and 6 show detailed cross-sections at different points on the clamp. Fig. 7 is a plan viewof aportion of the forward end of a fabric-making machine, showing the manner of mounting the clamp-cylinder and means for turning the same and the fabric carried in and upon the clamp -surface. Fig. 8 is a detailed view showing the face of the cam. Fig. 9 shows an edge view of the cam and the manner of mounting the same in connection with a frame part. Fig. 10 is a detailed view of the clamping plates or jaws.

In the drawings, A is a cylinder provided with a series of longitudinal guideways B, connected by cross-pieces a and mounted upon the axis V, which said axis is suitably journaled in the frame work of the fabricmachine with which it may be connected, the said cylinder being designed for adjustment in a proper position to receive the strand delivery from the fabric-making machine.

0 are spider-arms provided at intervals in the cylinder for strengthening the same and to serve as a supporting means therefor, the cylinder being bolted to the spider-arms, as at T.

O are plates or jaws loosely mounted upon the surface of the cylinder A in both trans verse and circumferential rows, the plates being provided with laterally-projecting lugs c 0, extending from the sides thereof and adapted to slide in grooves o c,pr0vided transversely within the guideways B.

D D are plates or jaws carried in substan tially the same manner as the plates or jaws C, but are carried in a circumferential line around the ends of the clamp and are what will be hereinafter referred to as the wedging plates or jaws.

' E are plates arranged longitudinally in the cylinder-guideways B and are carried in suitable grooves e therein. These plates extend some distance through the cylinder and are made convex, adapting them to be seated in the concave surface providedin the plates or jaws C. To facilitate the sliding movement of the plates or jaws C, the wedgingplates D and D, and the plates E within the guideways B, there are provided the short studs d, bolted or otherwise through the plates E, and the wedging-jaws D, which carry the antifrictionrollers d at their lower extremities.

F are rods carried within the guideways B in the cylinder, and each is supported in the stationary collar E in the plates E, the rear end of the rod being secured in the block D which is bolted or otherwise secured to the wedging plate or jaw D. On the rod and near its forward end I have shown a collar F, secured firmly thereto.

G is a spring carried on the rod Fand hearing between the collars E and F.

H are antifriction-rollers carried on the forward ends of therods F and coacting with the rollers d in engaging with the stationary cam I in giving a uniform pressure of the adjoining and intermediate jaws 0 upon the strands of the wire fabric. The cam I is suitably carried upon the framework of the machine and upon the dish P, it being upon the same center or centering at the same point as the cylinder-axis V, against which cam I or the irregular face thereof on either side the wedging-jaws D and D, through their antifriction-rollers Cl and H, are designed to bear and travel as the cylinder is revolved, and as the antifriction-rollers d and H traverse the irregular surface of the stationary cam I the said wedging plates or jaws D and D will be shifted simultaneously in opposite directions when the rollers are traversing the cam on the upward turn of the cylinder, thus relieving the pressure on the intermediate jaws C, and thus releasing the strands of the fabric, as the plates or jaws 0 when relieved from pressure move freely to disengage the strand wires held between their respective adjacent ends, and'when so relieved are ready again to receive the strands of the fabric as the cylinder revolves each respective series of jaws into position to engage the same.

The jaws or plates 0 are formed with herels upon their upper faces at each end, substantially as shown in Fig. 10 of the drawings, and by means of this bevel, which may be of a greater or less degree, as may be desired, the wires of the fabric are deflected or guided into position between the plates C, and the plates being free to move at the time when revolved into position to receive the strands will part readily to receive said strands, the bevel on the plates aiding in their proper separation therefor. The plates C are so arranged that the bevels of the adjacent plates are in line with the strands they are adapted to engage. In this manner the strands are adapted to pass between the jaws O, and as the cylinder continues to turn the aniifriction-rollers d and H will pass gradually down the declining face of cam I, and the wedgingplates D D will be relieved thereby, and under pressure of their spring connection, consisting of spring G upon rod F, the wedgingplates D D will be drawn toward each other and will press the plates 0 together, causing them to engage the wire strands carried between their respective adjacent ends. In this manner the said jaws G will alternately be relieved from pressure to allow the wires to pass between their adjacent ends and then will be subjected to pressure between the wedging-piates to cause the engagement of the strands.

Means are shown in Fig. 10 for rotating the clamp-cylinder. In that figure, T T are frame parts. U is a cog-wheel carried upon shaft U properly jou rnaled in the framework. U is a large cog-wheel fixed to shaft V, which supports the clamp-cylinder. R is a shaft carrying the belt-wheel r. u u, are sprocketwheels connected by a suitable sprocketchain. Power applied to belt-wheel r is transmitted to shaft R, sprocket-wheels a a, and sprocket-chain, shaft U cog-wheels U and U, and shaftV to the reel-cylinder; but other means may be provided that are suitable for the purpose,

The operation of the device is very simple. The cylinder A having first been adjusted upon the framework of a machine in connection with which it is designed to be used to accommodate its free and easy rotation and the parts of the complete clamp being in the relative positions shown in the drawings and the cylinder turned, the antifriction-rollers d and H, as best shown in Fig. 4, will be caused to traverse the irregular surface of the cam, and the said cam I being so arranged within the cylinder between the autifrictionrollers d and H that the said rollers on their respective rods F and jaws D, parallel with the cam, will traverse the cam and at the same time gradually cause the jaws in their respective guideways to open to facilitate in the engagement of the strands of the fabric from the machine. As the rollers pass from'tbe cam the pressure that has been brought to bear upon the springs G, bearin g between the collars E and F, will be removed, and the wedging-jaws D and D, which are at this time under pressure of the springs G, through the collars E and F will draw the outer jaws in opposite directions from either side of the clam p, thus bringing an even pressure upon the adjoining or intermediate jaws, causing them to uniformly and simultaneously grip the strands of the wire fabric. ment is purposed to begin at the top of the cylinder and to continue in such engagement until the said rows of jaws shall have been carried by the revolution of the cylinder to the lower portion thereof, when the antifriction-rollers d and H will again engage with the cam I, which will push the rods F rear- This engagewardly, thus relieving the pressure that has been brought to bear on the jaws 0 through the wedging-jaws D, and to also push the wedging-jaws D forward, thus relieving all pressure that has been brought to bear through them on the adjoining or intermediate jaws 0, thus releasing the said strands, so that the fabric may be carried rearwardly and rolled upon a suitable reel that may be provided for that purpose and that said jaws shall remain so open until in the revolution of the cylinder they shall be carried to the upper portion thereof and until {the strands of the fabric shall have been again carried between the jaws, when it is purposed that they shall again be engaged and held in the manner just previously described, the operation of each particular row of jaws of the series mounted upon the cylinder being identical with that just above described.

While I have shown rows of jaws in connection with a revoluble cylinder, asI regard it as the best mode of carrying out the idea of their use for the purpose of drawing out the strands of a fabric, yetI have other means of application of these jaws for the same purpose-namely, the carrying of a row of jaws horizontally back and forth lengthwise of the strandsthe parts thereof adjustable with relation to each other for the purpose of alternate opening and closing, substantially in the same manner herein set forth; but I deem it unnecessary to carry out such plan by further illustration.
