A block of solder 24 Fig. 4 is a transverse vertical section thereof, is positioned between each of said auxiliary dents taken on the line 4-4 of Fig. 3; and an adjacent main dent l1, being located a 55 short distance below the upper end of the auxiliary dent whereby there is thus provided a hooklike structure 25 at the lower part of each of the main dents I1 for the selective engagement of the warp ends during the leasing operation.

It should here be noted, however, that preferably the hook device 25 at the lower end of each of the main dents I'I is on 'the opposite side of the dent from the hook structure 2| which is provided in the upper portion of each of th main dents I1.

There is also provided means for preventing the warp ends which are not engaged by the hooks in the upper portion of the structure from becoming fouled with the offset portions 22 which are provided to maintain the .spacing of the dents at their upper ends. For this purpose there may be provided a cap member 26 4made of sheet metal mounted on the upper portion of the frame extending downwardly on both faces, the plate lportion 21 on one face thereof vextending to a point below the .offset 'portions 22 of the .dent Il.

During the initial entering of `-the warp in the leasing comb, the cap member will, of course, be removed therefrom to permit the "warp ends to be freely placed in their :respective dent spaces.

In Figs. 3 and 4 of the ydra-wingsthere isv illustrated a modified form of leasing comb I4 in which the bent-over tongue portions :I9 and inserted metallic blocks `2l) and 24 are y'dispensed with, and :in lieu thereof eachV of the dents Il is provided with struck-up hook members 2In and 25a, `the hook members 2l*EL :being provided in the upper portion ofthe frame vand the .hook

'members 25ab being provided .in .the lower portion thereof.

In 'the yform of leasing comb Ma illustrated in Figs. 3 and 4 there is also shown a different means of spacing the upper ends =of thedents, each of said dents being provided near its upper end with offsets 22a and 22b preferably Atwo or more in number `in each dent, as the provision of a .plurality of such offsets in veach `dent will -serve to prevent distortion ofthe individual dents. Furthermore, the-offsets of leach dent are staggered with relation tothe offsets of adjacent dents -so that said offsets will in each instance :bear against a portion of the adjacent dent which lies .fin 4the main plane thereof `and which fis resilient to Va sufficient extent to permit the warpends to pass into the dent spaces during vthe initial entering thereof.

The form of leasing comb shown in Figs. 3 and 4 is also .provided with 'a cap member 26 ias in the other form.

In Figs. 5 to 8, inclusive, 'there Vis shown the manner of manipulation -.of the warp with respect to the leasing comb '(of' either form) hereinbefore described. The warp,..after `leaving the Slasher, passes over a guide rod or roller G', extends through the leasing comb I4 by means of which the 'lease is for-med, and then passes over another guide rod or rollerSG2. The usual series of separator rods s1, s2, s3 and s4, are also provided, there being one of these .for vthe warp coming from each section Ibeam -on which the warp is primarily wound 'from the creel, the warp from each section beam spassinglover its respective separator rod. The separator rods are supported in suitable racksor standards `(not shown) between the guide rod G' and 'the 4leasing comb I4. These racks or standards `are arranged in such a manner so that each separator rod occupies two different positions inthe formation of the lease, these rods being moved successively from one position to the other as hereinafter more fully set forth.

The leasing comb I4 is so mounted that the same may be shifted sidewise with respect to the warp as is customary in the use of the common form of hook reed used for leasing, and if desired mechanism (not shown) of the same type as is used for shifting the common form of hook reed may be used for this purpose, or the same may be shifted by hand.

However, in carrying out the method of the Ypresent invention the leasing comb I 4 is also shifted to upper and lower positions respectively at different stages in the formation of the lease.

The rst step in the formation of the lease is shown in Fig. 5 of the drawings. In this instance, the comb or reed is in its lower position and the separator rods s1, s2, s3 and s4 are in their rearmost positions, that is, adjacent the guide -rod or roller G. It will be noted that in this position the wa-rp from -all the section beams extends through the dent spaces of the leasing comb between theV hooks 2I in the upper portion of the comb and the hooks 25 in the lower portion 'of the comb. The comb is now moved' sidewise with `respect to the warp, whereupon the separator rod s1 is moved from its rearward position as shown in Fig. 5 to the forward position as shown in Fig. 6. The warp which passes over the separator rod s1 will now be carried up free of the hooks 2|, whereupon the comb is then shifted sidewise with -respect to the warp but in the opposite direction. Separator rod s2 is `now moved forward from its rearward position, whereupon all of the warp ends controlled thereby -will be caught in the respective hooks 2I of the comb. The comb is again shifted sidewise lin the original direction and the Aseparator rod s3 is moved from its rearward to its forward position carrying with it -the war-p controlled thereby, raising the same upward free of the hooks 2'I. 'Ihe comb is again shifted sidewise in the opposite direction after which lthe separator rod s4 is moved forward from its rearward position causing the warp controlled thereby to be engaged by the hooks 2 I.

In this manner, the warps controlled by the separator rods s1 and s3 will be raised free of ythe Vhooks 2'I of the leasing comb I4 and the warps lcontrolled by the separator rods s2 and s4 will 'be engaged thereby, separating the same in two sheets as shown at the forward end of Fig. -6 and into the shed Vlike space thus provided, between the two sheets of warp, the leasing cord or rod vL' is inserted.

The leasing comb I4 is now raised to the position shown in Fig. '7 of the drawings, causing all of the warp to be free from engagement by the hooks thereof. A reverse actuation of the separator rods is now effected, step by step, the leasing comb, however, being in the proper position so that when the separator rod .s4 is returned from its forward to its rearward position, the Vwarp ends controlled thereby will be caught in the respective hcoks25in the lower portion of the comb. The comb :is `now shifted sidewise so that when the separator rod s3 is returned from its forward position to its rearwardpositionl the `warp ends .con- `trolled thereby will pass freely in -the dent spaces beyond the hooks 25 inthe lower portion of the comb. Likewise with the warps cont-rolled bythe separator rods s2 and s1 the leasing comb in each instance being shifted sidewise to selectively engage or permit the warp to pass, as may be required to effect the leasing.

When all of the separator rods are returned to their initial positions, the warp will again be separated by the leasing comb into two sheets as shown at the forward end of Fig. 8, and into the shedlike space thus provided, between the two sheets of warp, the leasing cord or rod L2 is inserted to complete the formation of the lease. The leasing comb iii may now be lowered to its initial positicn and the warp thereafter fed through the same free of engagement by the hooks thereof.

It will be noted that the method employed differs essentially from that in which a hook reed of the ordinary type is employed, in that the double lease is accomplished by the movement of the separator rods from their rearward to their forward positions and back again instead of requiring the same to be returned to their initial positions before the second part of the lease is taken. In this manner a considerable economy in the operation is obtained.

It will also be understood that in the practice of the method it is not essential that a leasing comb of either of the types shown be employed, as a reed having a permanently closed top may be used if the same be provided, in connection with each dent thereof, with two hooks suitably spaced to be operable in the manner hereinbefore set forth. However, the use of the comb-like device permits the warp to be more expeditiously entered in the dent spaces.
