United States Patent APPARATUS FOR WARP LEASING Claude W. Cain and John A. Yarbrough, Greensboro, N. C.

Application December 24, 1953, Serial No. 400,246

12 Claims. (CI. 28-40) This invention relates to apparatus for warp leasing, and it relates more particularly to a novel form of reed or comb for effecting the separation of the warp threads to permit the insertion of lease cords or rods. Such lease cords or rods are used to maintain an orderly arrangement of the warp threads, usually near the beginning and ending of the warp for the purpose of facilitating the drawing-in of the warp through the harness and reed of a loom, and also for facilitating the twisting in of a new warp when a previous one runs out.

In the formation of a lease in a warp it is important that the separation of the warp threads be accurately done, and that there be no fouling of any of the threads which would cause the same to be raised when they should be lowered in the formation of the lease, or vice versa. It is also important that the lease be formed with a minimum expenditure of time and labor.

Heretofore, in the use of hook reeds or combs for the separation of the threads to permit the insertion of lease cords or rods in the warp, it was necessary first to raise one or more sets of warps above the other or others to form two sheets, and then after the insertion of a lease cord or rod between the upper sheet and the lower sheet, the supporting rods were so manipulated as to cause a reversal of the arrangement so that the warps initially forming the lower sheet were brought to the top, forming a new shed for the insertion of the second lease cord or rod which is necessary to complete and maintain the lease.

The present invention, however, contemplates a device by means of which the warp may be simultaneously formed into two sheds with a crossing therebetween whereby the insertion of the lease cords or rods in their proper lease forming positions will be greatly facilitated.

The principal object of the present invention is to provide a device for warp leasing whereby the respective sheets of the warp will be separated, so that the lease cords or rods may be inserted, with a minimum of manipulation of the supporting rods over which the warp ends are guided.

A further object of the invention is to provide a device, of the character aforesaid, in the use of which likelihood of error by reason of any of the warp threads being disposed in the wrong shed, during the formation of the lease, will be reduced to a minimum.

A further object of the invention is to provide a device, of the character aforesaid, which is so constructed and arranged as to result in a considerable saving of time and labor in the formation of the lease.

The nature and characteristic features of the present invention will be more readily understood from the following description, taken in connection with the accompanying drawings forming part hereof, in which:

Figure 1 is a transverse section of a reed or comb for leasing purposes embodying the main or principal features of the present invention;

Fig. 2 is a front elevation of a portion of the reed or comb shown in Fig. 1;

Fig. 3 is a similar rear elevation thereof;

Fig. 4 is a view, to a certain extent diagrammatic, illustrating the manner of forming a lease by means of the reed or comb shown in Figs. 1, 2 and 3 of the drawings;

Fig. 5 is a fragmentary horizontal sectional view illustrating the arrangement of the warp passing from the section beams at one stage in the formation of the lease;

Fig. 6 is a similar view illustrating the arrangement of the warp at another stage in the formation of the lease;

Fig. 7 is a fragmentary elevational view of a portion 2. of one of the legs of one of the intermediate dents at the front, which dents are disposed between the others which are provided with hooks for engaging the warp to form the lease; and

Fig. 8 is a similar view of a portion of the other or rear leg portion of one of the intermediate dents.

It should, of course, be understood that the description and drawings herein are illustrative merely, and that various modifications and changes may be made in the device described and shown without departing from the spirit of the invention.

Referring now more particularly to Figs. 1, 2 and 3 of the drawings, there is therein shown a preferred form of hook reed or comb forming the principal part of the apparatus of the present invention.

As there shown, the reed or comb is made up of a series of evenly spaced dents, each having its outer marginal edges of U-shaped formation, and as specifically shown in which each alternate dent has vertical side or leg portions 10 and 20 respectively provided, along the outer margins thereof, with a plurality of hooks.

However, whatever form the dents of the reed may take, it is essential that the outer edge of the portion of each dent, which is disposed toward the front of the reed, be separated an'appreciable distance from the outer edge of the portion of the reed which is disposed to the rear for a reason, which will later appear, that the crossing of the warp between the upper and lower sheds must take place between said front and rear edges of the reed.

Each leg portion 10 at the front of each of the hook dents is provided with two hooks 11 and 12 spaced along its outer marginal edge. The hooks 11 and 12 are open toward the bottom and are bent in such formation as shown in Figs. 2 and 3 of the drawings, as to respectively extend into the dent spaces on each side thereof to selectively engage the warp ends when they are raised in the dent spaces in a manner to be hereinafter more fully explained.

Likewise, the outer marginal edge of the vertical leg portion 10 of each alternate dent may, if desired, be provided with a pair of hooks 13 and 14, respectively, open toward the top, and likewise bent into the adjacent dent spaces to engage any warp ends which are lowered in the dent spaces. Such hooks 13 and 14 are only provided when the hook reed is to be used in an arrangement with double sizing boxes, and when it is necessary to separate the warp for different treatment, which may be required by reason of different characteristics of the yarn used in the warp.

Likewise, each of the vertical legs 20 at the rear of each hook dent, is provided along the outer marginal edge thereof, that is, on the edge toward the rear of the reed, with hooks 21 and 22 formed similarly to the hooks 11 and 12, on the front leg portion 10, but preferably at a higher location. into the dent spaces on each side of the respective hook dents in which they are formed for the purpose of selectively engaging the warp ends which are raised in said dent spaces.

Also, the leg members 20 at the rear of each hook dent may be provided with hooks 23 and 24, similar to the hooks 13 and 14 of the vertical leg portion 10, but at a lower elevation and open toward the top, for selectively engaging such warp ends as may be lowered in the dent spaces, but here again, the hooks 23 and 24 are used only when a double sizing box is used as aforesaid. When a single sizing box only is employed, the hooks 13 and 14, and hooks 23 and 24 may be omitted.

Each of the intermediate dents, which is not provided with warp engaging hooks, also has vertical leg portions 30 and 40, at the front and rear, respectively, and the leg portions 30, at the same vertical location as the hooks 11 and 12, are provided with cutouts 31, and at the same vertical location where the lower hooks 13 and 14 are employed, the leg portions 30 of the hookless dents are provided with cutouts 32 (see Fig. 7).

In like manner, each of the leg portions 40 of each of the hookless dents is provided, at locations corresponding to the hooks 21 and 22 of the leg portion 20 of the hook dent, with a cut out 41, and in those reeds in which the hooks 23 and 24 are employed, the leg portion 40 of The hooks 21 and 22 likewise extend each of the hookless dents is provided with a cutout 42 (see Fig. 8).

Each of the hook dents is slitted in the upper portion thereof and the metal of the dent is formed outwardly on each side thereof, as at 50, to provide a spacer for each of said dents, and in like manner the hookless dents may also be provided with similar bent out portions as at 51, but at a different elevation. Of course, other forms of spacing projections may be used if preferred.

Preferably there is also provided at the top a removable cap member 60 which may be removed at the time the warp ends are being laid in the dent spaces or splits, but such cap member 60 is ordinarily in place as shown in Figs. 1 and 3 at the time the lease is being taken and while the warp is running through the reed as, for example, between the taking of a lease at the beginning and at the end of a warp which is being Wound on the loom beam.

The lower ends of the legs of the dents are mounted, in proper spaced relationship, in a base member 70 having slots 71 and 72 in which the extremities of the leg portions of the dents are mounted.

While the reed is adapted for use in forming a lease in a warp which comes from a number of section beams, the same is shown, however, with but two of such section beams A and B, and the warp threads which come therefrom will first pass over the rods 80 and 81 which are adapted to be raised and lowered. The warp is placed in the desired arrangement in the dent spaces of the reed, the cap member 60 having been previously removed, and extends over to the support rod 82 after which it may pass through the slasher and thence to the loom beam in the usual manner.

Where but two section beams A and B are employed, the warp ends coming from each of the section beams will be disposed consecutively in the dent spaces of the reed, but where more than two section beams are used, other and different dispositions of the warp ends in the dent spaces of the reed will be made as will be readily apparent to those familiar With leasing operations.

When a lease is to be taken, the warp is first tensioned sidewise, as shown in Fig. of the drawings, which will cause the warp ends passing through alternate dent spaces of the reed to bear aaginst one side of the hook dents at the front of the reed, and against the corner edges of the hookless dents at the rear of the reed, whereas, in the other alternate dent spaces, the warp ends passing therethrough will, at the front of the reed, bear against the corner edges of the hookless dents, and at the rear will bear against the corner edges of the hook dents. The rod 80 is now raised which will cause the warp ends a to be engaged by the hooks 11, and the warp ends a will be engaged by the hooks 22, as shown in Fig. 4 of the drawings.

The sidewise tensioning of the warp ends passing through the reed will then be changed, as shown in Fig. 6 of the drawings, so as to cause the warp ends in each dent space to bear against other and different corner edges of the respective dents.

The supporting rod 81 may then be raised to cause the warp ends which pass over the same to be lifted in their respective dent spaces, whereby the warp ends b disposed in alternate dent spaces will be engaged by the hooks 12 at the front of the reed, and the warp ends I) in the other alternate dent spaces will be engaged by the hooks 21 at the rear of the reed.

The lease will now be formed and a suitable temporary lease rod 90 of the relatively fiat sort, may be inserted in the shed formed in front of the reed, although if desired, the lease cord may be directly passed through said shed without any change in the arrangement of the warp.

A lease rod 91 may also be inserted in the shed provided at the rear of the reed, and this rod is also preferably of the relatively flat type. of suffcient width so as to enable the shed at the rear to be transferred through the reed for the purpose of inserting the second lease cord behind the crossing of the warp ends and thus hold the formation of the lease.

It will thus be seen that in the use of a reed of the peculiar formation herein described, a complete lease may be readily made in the warp with a minimum of manipulation. and with little likelihood of error by reason of any of the warp threads being disposed in the wrong shed in the formation of the lease. It will also be seen that in the use of such a reed a considerable saving of time and labor will be elfected.
