This invent-ion relates to a device for warp leasing, and it has particular relation to novel means for effecting the separation of the warp threads to permit the insertion of lease cords or 55 rods which are used to maintain an orderly arrangement of the warp threads, usually at the beginning and ending of thewarp. The formation of such leases in a warp facilitates the drawing in or layingin the Warp in a reed or comb, and, in some instances, the entering of the warp through the harness of a'loom.

The present invention is "more particularly adaptable for use in the formation of what are known as pin leases, that isto say, where the lease is so formed that the threads are separated in sets, one set for each dent space of the reed of the loom-in which the warp is subsequently to be mounted, although, of course, it should be understood that the device may, undercertain conditions, be used for the formation of other types of leases if so desired.

The pin leases above referred to are used principally when the warp is placed in a slasher preparatory to sizing the yarn. However, the invention is also adaptable to be used in the formation of a lease in a warp prepared on a Warping machine, and will also be found to be adaptable for the formation of various other types of leases.

The principal object of the present invention is to provide a simple, yet efficient, device for effecting the formation of a lease in a warp whereby the lease may-be formed in a simpleand expeditious manner, and by a simple series of manipulations.

A further object of the invention is to providea device for forming warp leases which may be inexpensively constructed.

The present invention contemplates the provision, in a comb or reed, of a dent having a hook portion of novel and peculiar formation for selectively engaging the warp --to take a loose therein.

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

Figure 1 is a front elevation of a reed or comb for leasing purposes embodying the main features of the present invention;

Fig. 2 is a face view of one of the dents of the reed or comb shown in Fig. 1, the same being provided with a hook portion of a peculiar formation;

employed in the reed or comb shown in Fig. 1, the same having its intermediate part formed without any hook portion therein;

Fig. 4 is an-enlarged perspective view of the hookportion of one of the dents shown in Figs. I

1 and 2; a

Fig. 5 is a longitudinal section illustrating, to a certain extent diagrammatically, an early step "in the formation of the lease by means of the device of the present invention;

Fig. 6 is a similar view illustrating a later step in the formation of the lease;

Fig, 7 .is a horizontal section through a portion of the reed or comb shown in Fig. 1 with the warp threads illustrated in operative relationship with respect thereto, when the first part of the lease is taken as in thestep shown in Fig. 5; and

Fig.8 is a similar view when the second part of the lease is taken as in the step shown in Fig. 6.

It should, of course, be understood that the drawing and description herein contained are illustrative merely, and that various modifications and changes may-be made in the structure disclosed without departing from the spirit of the invention.

Referring more particularly to Figs. 1 to 4 of the drawing, there is there shown one form of constructionofa leasing reed .or comb l0 embodying the principal features of the present invention andparticularly adaptable for use in the formation .of a pin lease in a warp. Said device consists of .a suitable frame ll havingside struts l2, and disposed between side struts I2, hook .dents l3 and plain dents M are suitably spaced in alternate relationship, said dents being rigidly secured at their lower ends in the frame ID in the usual manner of construction of soldered reeds.

As there shown, each of the dents l3 and I4 comprises a thin flat strip of metal, the dents l3 being each provided intermediate its ends with a hook portion of peculiar formation. At the place where the hook portion is provided, the dent I3 is cut out as at IS, the preferred shape of the cutout being illustrated in Figs. 2 and 4 of the drawing. The cutout is so shaped as to provide a sloping or inclined margin l6 extending from one edge of the dent to a medial point, thence extending downwardly parallel to the side edges of the dentas at H. 50

At the lower end of the cutout I5 adjacent the edge of the dent, there is provided an upwardly extending projection 18 which constitutes a hook adapted to function in a manner to be hereinafter more fully set forth to effect the leasing operation. It should be noted that the hook provided by the upwardly extending projection I8 is disposed entirely in the plane of the dent strip, and does not project beyond either side face thereof.

The other dents M are made plain,'without any hook portions, and ordinarily the dents will be disposed in spaced relationship, a hook dent l3 alternating with a plain dent 14. It will be noted that by this arrangement, when viewed from the front and rear, the dent spaces will be free and unobstructed, so that as long as the warp extends straight through the dent spaces, none of the ends thereof will be engaged by the hook portion of the dents l3.

The reed or comb formed as aforesaid is preferably open at the top to permit the ready insertion of the warp ends in the proper dent spaces, although it should be noted that, if desired, a cap (not shown) may be placed over the top of the reed or comb, as is sometimes done in devices of this character. In other instances, the reed or comb may have the upper ends of the dents rigidly secured in a manner similar to structure at the bottom. In still other instances, the dents may be supported at their lower ends by suitable springs, as is commonly done in expansion combs which permit the number of dents per inch to be varied to suit the requirement of the user.

The invention relates primarily to the construction and arrangement of the dents, but not to any particular manner in which they may be supported.

In the manipulation of the warp to form a lease therein, the comb or reed may be initially positioned, or shifted sidewise if necessary, to cause the warp ends which are located in each of the dent spaces to bear against one set of faces of the dents, as, for example, in Fig. 7. As illustrated in Fig. 5 of the drawing, one of the supports S of the warp is now lowered from the position shown in dotted lines to that shown in full lines. As the warp is thus lowered, the warp ends in each alternate dent space will be caught by the hooks l8 of the dents l3, and the warp ends which are located in the other alternate dent spaces will pass freely along the smooth faces of the dents l4 against which they bear, and a shed will thus be formed, as shown in Fig. 5, into which may be inserted the first lease rod or cord L After the lease rod or cord L is inserted in the shed formed as aforesaid, the warp may again be raised by elevating support S to its initial position, as shown in dotted lines in Fig. 6, and the reed may then be shifted sidewise to cause the warp ends, which previously bore against the smooth faces of the dents 14 to now bear against the faces of adjacent dents l3. The support S may then again be lowered from the position shown in dotted lines in Fig. 6 to the position shown in full lines, it being noted that as the support S is thus lowered, the warp ends which encounter the hooks l8 of the dents 13 will be caught in said hooks, and the other warp ends which bear against the faces of the dents I4 will pass downwardly without being engaged by any of said hooks, thereby forming a new shed into which the second lease rod or cord L may be inserted to complete the lease.

Of course, it will be apparent that instead of raising or lowering the warp as above described, the lease sheds may be formed by leaving the warp supports stationary and causing the comb or reed H] to be raised and lowered, whereby the hook portions of the dents l3 will selectively engage the warp ends in the same manner as above set forth to form the lease sheds; and it will also be apparent that instead of shifting the reed sidewise, as above set forth, the reed may be left stationary, and the entire body of the warp shifted sidewise but in a contrary direction.

It will be noted that the manipulation for the formation of the lease is quite simple and may be expeditiously performed without requiring any particular skill on the part of the operator; or on the other hand, the device may be readily incorporated in an automatic machine without undue complication.
