METHOD OF MAKING RIVET-CLOTH.

Specification of Letters Patent.

Original application filed November 20, 1912, Serial No. 732,427. Divided and this application filed March To all whom it may concern Be it known that I, Jnnonn T. Rtrrnuntnc,

and useful Method of Making Rivet-Cloth,

of which the following is a specification.

This is a division of my application Serial No. 732,427, filed November 20, 1912.

This invention relates to the immuli'acture ot a cloth without pile having when produced on the loom, perforations therethrougl'i arranged at intervals both longitudinally and across the goods.

The principal type of fabric to which this invention relates is the soazalled rivetcloth which is used in the manufacture of rubber tires, but it is capable of use for the production of any such fabric.

The invention involves im1n'ovcments in the method of making the rivet cloth in such a manner that it will be a complete article as it comes from the loom without the necessity of picking out all the warp and filling threads occupying those spaces which are to be left vacant.

Reference is to be had to the accompanying drawings, in which- Figure 1 is a plan of the fabric on the loom showing it as it appears immediately after the weaving operation; Fig. 2 is a similar view of the fabric after the rods:

are withdrawn and the left-hand edge trimmed oil, and Fig. 3 is a similar view of the completed rivet cloth.

So far as I am aware rivet cloth has been manufactured heretofore by weaving a continuous length of cloth and having the filling.

inserted continuously from end to end of a continuous warp, but the warp and filling in the places where the openings are to appear are of a different color from the main body of the fabric, and after the fabric is woven they are drawn out. This is an expensive method, involving not only a slight complication in the weaving, but especially taking considerable time in the drawing out of the colored threads, and the wasting of these threads. This invention is designed Serial No. 756,408.

chiefly to avoid this waste by making the fabric originally with the openings therein, so that the threads will not have to be cut and drawn out, or at least only two will for each space, and also to provide a simple method of Freeing the threads which are drawn out in order to leave only a firm Fabric.

Referring now to the drawings, for the purpose of producing the rivet cloth or other fabric of a similar nature in a cheap and expeditious manner, the following arrangement is provided. First, the warp A is ar ranged to consist of a plurality of sections ol main warp threads (1 arranged in a plurality of series of a given number of threads each, say for example eight. These threads are separated by spaces substantially oi. the same width as the width of a section of these warp threads. At the edges of these sections are binding warp threads a which are smaller than the main warpthreads and thus are capable of being more closely woven in and perform a Function similar to the sclvage in that they hold the edges of the sections. Outside the main warp are two warp threads (1%, the purpose of which will be described hereinafter. The filling is woven into these warps in the usual manner the usual roller chain (not shown) being employed to operate the jacks, but one of the jacks which operates only after a definite number of picks are made, as for example ten, is arranged so as to be actuated at regular intervals, as for example, at every tenth pick in the embodiment illustrated in the drawings. In other words when ten picksot' filling have been inserted in the warp, a connection will be actuated to move the shipper handle and thus stop the loom. Then the operator inserts a rod 25 into the warp as indicated in Fig. 1. Each of these rods has a book 26 on the end. Connected with the main or crank-shaft means is provided to engage a hook 26 of one of the rods 25 at regular intervals during the operation of the loom. These parts are so timed that as the cloth 'lj'ecds over the breast beam these means will come into engagement with the respective hooks 26 when these hooks reach a predetermined point. In this case then these members will operate once for every ten picks to draw out each rod 25.

Referring especially to Fig. 1, it will be seen that the filling B is woven into the fabric to form the usual filling strand Z across the same, but that just before the loom stops, that is 011 the ninth pick in this case, a loop .7) is formed on one side of the fabric around the side warp thread a It is then woven into the fabric and extends out on the other side at 6 around the other strand o of the rod 25 which has been inserted and is woven in again forming a second loop 6 on the other side. It then continues to be woven in for the desired number of picks, for example, ten, when the loom again stops and the next rod 25 is inserted. It will be understood, of course, that these rods 25 can be inserted by the means which are em ployed for introducing pile wires in carpets, on carpet looms and the like, without departing from the scope of the invention as expressed in certain of the claims and in fact so far as the method is concerned can be both inserted and withdrawn by hand. The fabric as thus produced on the loom itself thus assumes the form shown in Fig. 1. Now as the fabric passes on, and preferably before the rods 25 are withdrawn, it is caused to come into contact with a fixed or adjustable blade at the side on which the loops 6 are located. This blade is located directly at the edge of the main warp so as to sever the loops b of the filling. This leaves the fabric when the rods are withdrawn in the form shown in Fig. 2.

F or the purpose of insuring that the filling actually remaining in the fabric shall be firmly woven therein and not likely to spread out in the rectangular spaces to be left, an extra filling thread 6 is left on each side of each space. These are the ones which are now connected with the strands b and as their opposite ends are clipped it will be obvious that each pair of them can be drawn out simultaneously with great rapidity and without interfering with the strength and firmness of the fabric. In this way the expensive operation of clipping and pulling out by hand all the threads to form spaces in the cloth, is, for practical purposes, eliminated and this reduces the cost of the material very essentially. On account of having the end strand that comes next to the rod drawn out the filling that remains is firm. secure and uniform. In this way this kind. of fabric is inexpensively manufactured and is made uniform throughout as the hand operations are dispensed with. At the same time a fabric is secured which is an improve- Then it passes to the other side ment over the old hand-drawn rivet cloth in the particulars above specified.

Although I have illustrated and described only a single embodiment of the invention I am aware of the fact that modifications-can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be strictly limited to the precise order of steps herein shown and described, but

lVha-t I do claim is l. The improvement of the art of making woven fabrics without pile which consists in inserting smooth uniform rods at intervals in the warp parallel with the filling, after weaving withdrawing said rods to leave a space between two adjacent sections of filling, and thereafter drawing out the thread on each side of each space.

2. The improvement in the art of weaving fabrics which consists in inserting rods parallel with the filling at intervals in the warp, weaving the filling thread adjacent to each rod to a point beyond the edge of the fabric on one side and the next thread on each side beyond the other edge of the fabric, with drawing the rods, cutting the last named extendingfilling threads at the edge of the fabric, and then drawing out the first named extended filling threads from the other edge of the fabric.

3. The improvement in the art of making fabrics which consists in providing a warp having two threads at a distance from the main body of the warp, inserting filling in the main body of the warp in a series of sections, inserting rods in the warp between each two of said sections, extending the threads of the filling at one end of each rod and on both sides thereof beyond the edge of the main body of the warp and around said side thread thereof, extending the other ends of both of said threads beyond the other edge of the main body of the warp and around the other side thread thereof and back into the fabric, withdrawing the rods, cutting the last named extending filling threads at the edge of the main body of the warp, and drawing out the pairs of first named extending filling threads from the main body of the warp.

t. The improvement in the art of weaving fabrics, which consists in providing a warp having a main body divided into sections with a free space between each two sections, and two side warp threads at a distance from the main body of the warp, inserting filling in the main body of the warp in a series of sections spaced apart, extending the threads of the filling beyond the edge of the main body of the warp and around the side thread thereof, extending the other ends of both of said threads beyond the other edge of the main body of the warp and In testimony whereof I have hereunto set around the other side thread thereof and my hand, in the presence of two subscribing back into the fabric, cutting the last named witnesses.

extending filling threads at the edge of the JEROME T. RUTLEDGE. main body of the Warp, and drawing out \Vitnesses:

the first named extending filling threads JENNY M. GODDARD,
