EUGENE PERRIN, or PORT JEE-vIs, new YORK, AssIeNon or ONE-HALF TO HENDRIK VAN BREDER-ODE, or MIDLAND PARK, NEW JERSEY.

LOOM.

Application-filed. June 4, 1925. Serial No. 34,821.

To (ZZZ 1071 0772 it may concern:

Be it known that I, EUGENE. PnRnIN, a citizen of France, residing at Port Jervis, in the county of Orange and State of New York, have invented certain new and useful Improvements in Looms, of which the following is a specification.

This invention relates to looms in which the fabric is woven two-ply with a fold at one side, or in other words woven folded longitudinally, so that when it is removed from the loom and unfolded its width is represented by the combined widths of the two plies in which it was woven. It is known that in weaving in this manner the warp threads which are at or near the side of the warp corresponding to the fold become more closely related to each other than the warp threads elsewhere in the goods, so that in the finished product, when the sheet of fabric is unfolded and laid out flat, there is in effect a blemish running lengthwise of the goods and represented by these tooclosely related warp threads. This fault is caused by the warp-threads at the side of the warp corresponding to the fold being unsupported against displacement toward the opposite side by the pull of the weft when the shuttle is traversing toward the latter side of .the warp, so that the threads at the fold-side become unduly crowded together. My object is to prevent this, and I accomplish the desired result by providing a fold-guide which is fixed to some rigid part of the loom at the open side of the folded fabric and projects between its two plies and bears against the folded fabric within the same and at its fold and more or less close to the fell, or beating-up line of the reed. This fold-guide is preferably adjustable transversely of the fabric, so as to maintain the proper tension for preserving the fold-forming warps in the desired spacing.

In the drawing,

Fig. 1 is a view of the forward part of a loom equipped with my invention;

Fig. 2 is a sectional view on the line 2-2, Fig. 1;

Fig. 3 is a view showing in plan and righthand elevation the fold-guide;

Fig. 4 is a view showing the breast beam in fragmentary section and the fold-guide and its supporting bracket in left-hand elevation; and

Fig. 5 is a front elevation of the foldguide, showing the fabric as it exists folded in the loom in transverse section.

a is the loom frame and 6 its breast beam which may have a roller or other guide 0 over which the finished fabric A is extended. The sheet of warp B and finished fabric is advanced as usual during the weaving in a given path by a driven take-up means including a sand-roller d, or equivalent, the cloth beam 6, and suitable guides f. g indicates any suitable means, as a harness, for manipulating the threads of the warp B to form she'ds. For this purpose in accordance with the character of weaving to which this invention specifically relates, the warp is divided into two sections, one above the other, and sheds are formed in each section independently of the other by proper and well known operations of the harness. being referred to, the filling carrier or shettle h, when a shed is formed in one of the sections or sheets of warp, is passed through that shed and then back again and subsequently passes through a shed formed in the othersection and then back again, always entering one shed after leaving the other from-the same side of the warp, so that the finished goods will be woven two-ply and with its plies joined and thereby forming a fold in the fabric at one side and not at the other. The plies are indicated at A A in Fig. 5, which figure shows them unjoined at the left side and joined and thereby forming a fold A at the right side.

z'indicates the lay or batten, movable back and forth in the usual way, and j the reed,

carried thereby, for beating-up each. shot of weft or filling to the fell of "the fabric.

The frame may include an angle bracket 71: which is attached to the back of the breast beam so that one arm is vertical and the other is horizontal and about flush with the top of the breast beam. The latter arm has set-screws Z. This bracket carries the fold-guide which is shown best in Fig. 3 as including a flat bar at having at one end a flat arm n projecting therefrom substantially at right angles thereto, the other end of the arm having longitudinal slots 0 to receive the set-screws Z when the fold-guide is secured in position as shown in Fig. 1. The bracket 71 1's arranged at the left path 1 of the fabric as shown in this figure, and

According to the kind of weaving the fold-guide projects across said path between the tWo plies of the fabric With its arm bearing against the inside of the fold A? of the fabric. :l't is preferable to round, as at n, that corner of the :arm n which adjoins the fold A and is at the free or rear end of the arm, so that in the advance of the fabric the latter will not catch thereon. On account of the slots 0 it will be apparent that the fold-guide may be adjusted across the path of advance of the fabric so ':as to obtain the needed pressure onthe'same at the fold. I

it will be seen that when the loom is .operated the fold-guide maintains: the righthand or folded side of the tWo-p'ly fabric and near the fell off the cloth in a definite position, that is against being drawn to the left by the pull of the filling each time the shuttle is thrown to the left, and that thereby the crowding together of the Warp threads at the right or foldside of the fabric is prevented, they being kept spaced the same all the other Warp threads, withthe result that when the fabricisremoved from the loom and laid out flat, or unfolded, the

cloth will give the same appearance .on the line of the told as elsewhere.

Having thus fully described my -inven tion What I claim and desire to obtain by Letters Patent is: i 1.111 a loom, the combination of i a' frame having abreast-beam, means to advance the Warp in a given path .overthe breast-beam, means to form independent sheds in the Warp one above the other, a filling carrier adapted to pass back'and forth through one and then the other shed allternately, whereby fabric Wilibe formed in two plies dined and thereby forming a fold in thefaibric atone side and not at the other, and a fold guide fixed to the frame and projecting across said path in position to be contained between the two plies and bear against said fold at the inside thereof.

2- In a loom, the combination of a frame having a breast-beam, means to advance the Warp in a given path over the breastheam, means to form independent sheds in the Warp one above the other, a filling carrier adapted to pass back and forth through one and then the other shed alternately, whereby fabric Will be formed in two plies joined and thereby forming a fold in "the fabric at one side and not at the other, and a fold-guide fixed to the frame and projecting across saidpath in position to be contained between the two plies and bear against said fold at the inside thereof and being also adjustable on the frame across said path.

In a loom, the combination of a frame having a breast-beam, means to advance the warp in a given path over the breast-beam, means to form independent sheds in the Warp one above the other, a filling carrier adapted to pass back and forth through one and then the other shed alternately, where by fabric will be for-medfin 'tWo plies joined and thereby forming a fold in the fabric atone side and not at "the other, and a foldguide consisting of a bar fixed to the frame and projecting across said path in position to be contained bet-Ween the two plies and having a rear-Wardly projecting arm at its free end arranged to bear against said foid at the inside thereof.

in testimony whereof I afiix my *sigirature.
