Application filed April 8, 1932. Serial N0. 604,018.

This invention relates to looms for weaving tuft pile fabrics, and more particularly tuft pile fabrics wherein the pattern of the pile surface is reproduced upon the back.

Tuft pile fabrics, such, for instance as Axminster and like carpets and rugs, as ordinarily woven present an objectionable looseness 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 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 become detached from the ground fabric, and the pattern on the back, as well as the pile surface, presents a distorted and unsatisfactory appearance.

The ordinary Axminster loom is provided with a fixed breast plate over which the fabric passes as it is woven and loops of the tuft yarn which may pass about a back weft shot are supported upon the surface of the breast plate near its rear edge. On the beat up of the lay the reed approaches the rear edge of the breast plate but terminates its beat-up action short of the rear edge of the breast plate with the result that the binding weft shot for the pile forming tufts is not driven into close binding relation with the tufts and the fabric presents a loose weave with the objections above noted.

One of the objects of the present invention is to produce a tuft pile fabric of the AX- minster 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 moved rearwardly at intervals and is returned to its front position by a part carried by the lay on the beat up of the binding weft shot for the pile forming tufts, the effect being that on its rearward movement the back legs of the pile forming tufts are turned upwardly, the loops of the tufts are supported by the breast plate, and while so supported the advancing lay beats up the binding weft shot I for the tufts and returns the breast plate to front position, thus drawing the tufts tightly about the holding back shot and pro ducing a close weave of the ground fabric giti: a clear and well defined pattern on the ac The invention and novel features thereof will best be made clear from the following description and accompanying drawings of one good practical form or embodiment thereof.

In the drawings Fig. 1 is a sectional side elevation of a tuft pile fabric loom containing the present invention;

Fig. 2 is a. fore and aft section on an enlarged scale showing the movable breast plate being moved to its rearward position, the lay and reed being shown in elevation;

Fig. 3 is a view similar to that of 2 showing the relation of parts as the breast plate is being moved frontwardly;

Fig. 4 is a view of the breast plate extending transversely of the loom; and

Fig. 5 is a perspective broken out detail of the breast plate and its associated parts.

The invention will be described in connection with a loom of the well known Axminster type and as indicated in Fig. 1 the loom frame 1 may be of usual construction and at the rear portion thereof supports the warp beams 2 and 3 from which the warp threads pass frontwardly through the usual weaving mechanisms.

Rising from the loom frame 1 are the standards 4 having brackets 5 for the support of the usual sprockets 6 about which the tube frame carrier or chains pass. The carrier or chains 7 support a number of tube frames, 8 as usual in the Axminster loom and such tube frames carry the pile forming tuft yarns. The tube frames 8 are taken from the carrier or chains 7 by a transferrer 9 to present the pile forming tuft yarns to the weaving point.

As indicated in Fig. l the cutter carriers 10 and 11 have the usual cutters for parting or cutting the pile forming tufts after the latter have been introduced about the holdin weft shot at the weaving point.

ounted upon the shaft 12 is the lay 13 having a reed 14 and the lay is given its movements towards and from the front of the loom by a rod or connection 15 actuated by a going part of the loom.

The comb 16 is given its appropriate movements as usual to turn up the rear legs of the tuft yarns and then recedc by means of actuating connections 17 and 18. As the fabric is Woven it passes frontwardly about the spike roll 19.

All of the parts so far described may be of usual construction now well known to those familiar with Axminster or tuft pile fabric looms and further elucidation of these features is unnecessary.

Mounted upon the front portion of the loom is the breast beam 20 which forms a convenient support for the movable breast late 21 which is mounted on the breastam for movements rearwardly and frontwardly.

In accordance with the present invention the breast plate 21 is to be moved rear- Wardly at intervals and then freed from the moving means that it may be returned frontwardly on the beat-up by means carried on the lay.

In the present instance of the invention the breast beam 20 and the movable breast plate 21 are associated for sliding movement of the latter nearwardly and frontwardly and while various means may be devised for effecting the relative movement of the breast plate and the breast beam, in the present instance the breast plate 21 is connected to the breast beam 20 at each end of the breast plate by bolts or screws 22 which pass through elongated slots 23 in the breast plate with the result that the breast plate may be moved backwardly and frontwardly relative to the breast beam and in order that the breast plate may be supported and guided at intervals the breast beam has secured thereto the supporting lugs 24 which extend beneath the breast plate, and, as indicated in Fig. 4, two or more of such supporting lu may be utilized.

Ti. is likewise desirable that the breast plate may be held from displacement vertically and to this end the breast beam 21 has secured thereto the guides 25 of which there may be an appropriate number to effect the purpose. From the construction thus far described it will be apparent that the breast plate 21 is mounted for movement on the breast beam in a direction backwardly and frontwardly.

As more clearly indicated in Figs 2 and 3 the guides 25 are connected to the breast beam by screws 26 and the rearwardly projecting end portions of the guides 25 overlie portions of the breast plate. In the present instance of the invention the upper surface of the breast plate 21 adjacent the guides 25 is provided with a recess 27, and a recess 28 is preferably formed at the gooseneck portion of the guides 25 to permit the breast plate a limited but substantial movement backwardly and frontwardly.

The breast plate 21 is )rovidcd with a rib or projection 29 extending longitudinally thereof and formed with openings at intervals for the rearwardly extending portion of the supporting lu s 24, the construction being such that wh'le the lugs 24 support the breast plate they do not interfere with the movement of the breast plate backwardly and frontwardly.

Secured to the rib or projection 29 of the breast plate at intervals are the arms 30 which afford means for engagement with an actuating member or members for moving the breast plate rearwardly. In the present instance the arms 30 are provided with pins 31 which enter elongated recesses 32 formed in the upper portion of the actuating members 33.

The function of the actuating members 33 is to move the breast plate rearwardly at intervals and then free the breast plate for movement frontwardly by a part carried on the lay on the beat up of the binding weft shot for the tufts, and since the actuating members are similar a description of one will be sufficient. Referring to Fig. 1 the actuating member 33 is mounted for rocki movement on a transversely extending she 34 which may be carried in bearings 35 secured to the front girth 36 of the loom.

Connected to the actuating member 33 is a rod 37 which if desired may be provided I with a turn buckle 38 for adjustment purposes and the rear end portion of the rod 37 is connected at 39 to a lever 40 mounted for rocking movement on a support 41 carried by suitable brackets 42 secured to the rear girth 43 of the loom.

The lever 40 is provided with a roller 44 and under the impulse of a spring 45 secured at one end to the upper portion of the lever 40 and at its other end to a fixed portion 46 the roller 44 is held in contact with a surface of a cam disk 47 which is mounted upon the cam shaft 48 actuated by a going part of the machine.

The cam disk 47 carries a cam 49 which, as it passes under the roller 44 gives the actuator 33 a movement to carry the breast plate 21 rearwardly, and then free the breast plate that it may rest in its rearward position and be held there by the frictional engagement of the breast plate with its guiding means.

From the construction thus far described it will be apparent that the actuating member 33 moves the breast plate to a rearward position under the impulse of the cam 49 and then immediately the actuating member moves back to its normal position, as indicated by dotted lines in Fig. 2, thus freeing the breast plate in the rearward position to which it as been moved.

It may be desirable at times to adjust the rearward position of the breast plate or vary its position for reasons that will later app and consequently the actuatin memb is provided with a lug 50 in which is threaded an adjusting member or screw 51 whereby the effective length of the slot 32 of the actuating member 33 may be varied and consequently the rear position to wlii the breast plate is moved may be changed.

In the particular construction of the tuft pile fabric selected for illustration of the in vention antL its operation there is a surrace weft shot a, a tuft holding weft shot 5 and a binding weft shot a but obviously the number of weft shots will be varied in accordance with the construction of the fabric to be woven.

During the insertion of the surface weft shot 0; and the holding weft shot 5 about which the tuft yarns d are passed the breast plate 21 is in its front position. Upon the insertion of the binding weft shot 0 for the tuft yarns, the breast plate is moved rearwardly, as indicated in Fig. 2, thereby turning the rear leg of the tuft yarns upwardly and supporting the loops thereof, and at this time also the comb 16 is actuated to complete the upturning movement of the tuft yarns. As the binding weft shot 0 is beaten up the reed 14 engages the rear edge portion of the breast plate 21 and moves the breast plate frontwardly thereby causing the binding weft shot 0 to draw the loop of the tuft yarns tightly about the holding weft shot as indicated in 3.

The result of the general opera scribed is to tighten the loops of t about the holding weft shot to make c weave and securely anchor the tuft yarns in the backing fabric with the produ tion 0 well defined pattern on the heel: of the C011} pleted fabric.
