Claims.

This invention relates to tuft pile fabric looms and more particularly to such looms for the production of a well defined pattern on the back.

Tuft pile fabrics, such as Axminster and like 5 carpets and rugs as ordinarily woven present an objectionable looseness in the weave of the backing fabric and of the pile forming tufts where they pass about the tuft holding weft shot, due to the fact that the binding weft shot for the pile forming tufts is beaten up under conditions which fail to draw the tufts tightly about the holding weft shot, with the result that the pile forming tufts work loose and frequently become detached from the ground fabric, and the pattern on the back, as well as the pile surface presents a distorted and unsatisfactory appearance.

One of the objects of the present invention is to produce a tuft pile fabric of the Axminster or similar type wherein the objections heretofore existing may be eliminated, the pile forming tufts be drawn tightly about the holding weft shot, and a well defined pattern of the pile surface be produced upon the back of the finished fabric.

In accordance with the present invention the breast plate is formed of two parts, one fixed and the other movable, and the movable part or nose of the breast plate extends rearwardly of the fixed breast plate, and means are provided for moving the rear portion or nose of the breast plate rearwardly at intervals to support the loops of the last row of pile forming tufts and then withdraw the nose frontwardly on the beat up of the binding weft shot. The result of this condition is that when the pile forming tufts are placed about the holding weft shot and are at that time liable to be displaced, they are held with the loops of the tufts passing about the hold ing Weft shot, and at the finishing portion of the beat up of the binding weft shot the nose or rear portion of the breast plate is withdrawn frontwardly to permit the binding weft shot to draw the loops of the tufts tightly about the holding weft shot thereby producing a close and even weave of the backing fabric with a well defined pattern on the back.

The invention and novel features thereof will best be made clear from the following description and accompanying drawings of one good embodiment thereof.

In the drawings:-

Fig. 1 is a side elevation showing sufficient portions of an Axminster or tuft pile fabric loom to make clear the association of the present invention therewith;

Fig. 2 is an enlarged detail showing the relation of parts when the pile forming tufts have been passed through or between the warp threads ready to be engaged by the holding weft shot;

Fig. 3 is a similar view showing the comb as having turned the rear leg of the last row of 5 pile forming tufts upwardly with the loops passing about the holding weft shot;

Fig. 4 is a similar View showing the rear portion or nose of the breast plate as having been moved relatively to the fixed breast plate in a 10 rearward direction to support the loops of the last row of pile forming tufts and a binding weft shot has been laid in the shed;

Fig. 5 is a similar view showing the relation of parts during the completion of the beat up of the 15 binding weft shot; and

Fig. 6 is a detached detail of the rear part or nose of the breast plate.

The invention will be herein described in connection with the loom of the well known Ax- 20 minster type, and as indicated in Fig. l, the loom frame I may be of usual or suitable construction for the support of the operating parts.

Rising from the loom frame are the standards 2 which afford a convenient support for brackets 3 25 having suitable bearings for the carrier or chain sprocket 4.

In looms of this general type the tube frames 5, only one of which is shown, are taken from the carrier or chains to present the pile forming tuft 30 yarns to the weaving point and, as shown in Fig. 1, the tube frames 5 are taken from the carrier or chains by a transferrer 6 which may be of usual construction to present the pile forming tuft yarns to the weaving point. 35

The lay l is mounted upon a shaft 8 carried by the loom frame and is actuated to beat up the weft shots by means of a rod 9 actuated from a going part of the loom.

As usual in Axminster looms the tuft yarns 40 are out, after they have been secured to the backing fabric, by the usual cutters l0 and II, but since the parts thus far described may be of usual and well known construction detailed description and illustration of such well known features is unnecessary for proper disclosure to those skilled in the art.

At the front of the loom is the breast beam I2 which affords a convenient support for the 50 novel breast plate of the present invention.

It is also usual in looms of this type to provide a comb and actuating mechanism therefor to cause the comb to turn the leg of the tuft yarn upwardly between the warp threads and about 55 What is claimed is:

1. In a tuft pile fabric loom, the combination of the breast beam at the front of the loom over which the fabric passes as it is woven, a breast plate mounted on the loom frame rearward of the breast beam and having a fabric supporting surface on which the fabric rests as it is woven, a nose mounted at the rear of the breast plate and having a fabric supporting surface in the plane of the fabric supporting surface of the breast plate, rods for supporting the nose rearward of the breast plate and means for moving the nose rearwardly from and frontwardly towards the rear end of the breast plate with the fabric supporting surfaces in thesame plane.

2. In a tuft pile fabricv loom, the combination of the breast beam at the front of the loom over which the fabric passes as it is woven, a breast plate mounted on the loom frame rearward of the breast beam and having a fabric supporting surface on which the fabric rests as it is woven, a nose mounted at the rear of the breast plate and having a fabric supporting surface in the plane of the fabric supporting surface of the breast plate, rods for supporting the nose rearward of the breast plate, guides through which the rods pass and by which the rods are supported, and means for moving the nose rearwardly from and frontwardly into contact with the rear end of the breast plate with the fabric supporting surfaces in the same plane.

3. In a tuft pile fabric loom, the combination of the breast beam at the front of the loom over which the fabric passes as it is woven, a breast plate mounted on the loom frame rearward of the breast beam and having a fabric supporting surface on which the fabric rests as it is woven, a nose mounted at the rear of the breast plate and having a fabric supporting surface in the plane of the fabric supporting surface of the breast plate, rods for supporting the nose rearward of the breast plate, a cross bar connecting the rods, and means acting through the cross bar for moving the nose rearwardly from and frontwardly into contact with the rear end of the breast plate with the fabric supporting surfaces in the same plane.

4. In a tuft pile fabric loom, the combination of a breast beam, a breast plate mounted on the loom frame rearward of the breast beam, a nose at the rear of the breast plate, rods extending rearwardly of and beyond the breast plate, connections between the rods and nose for supporting the nose at points rearward of the breast plate, guiding supports for the rods through which they pass, and means for moving the nose bodily from the rear end of the breast plate and frontwardly into contact with the rear end of the breast plate while maintaining the fabric supporting surfaces of the breast plate and nose in the same plane.

5. In a tuft pile fabric loom, the combination of a breast beam, a breast plate mounted on the loom frame rearward of the breast beam, a nose at the rear of the breast plate, rods extending rearwardly of and beyond the breast plate, adjustable threaded connections between the rods and nose for supporting the nose at points rearward of the breast plate, guiding supports for the rods through which they pass, and means for moving the nose bodily from the rear end of the breast plate and frontwardly into contact with the rear end of the breast plate while maintaining the fabric supporting surfaces of the breast plate and nose in the same plane.
