Klampenhorg, Denmark, and Poul Ejnar Schou, Ordrupvej No. 94, Charlotteniund, Denmark Filed Dec. 21, 1962, Ser. No. 246,427 8 Claims. (Cl. 28-40) This invention relates to devices for warp leasing, and more particularly to a novel form of comb for effecting the separation of warp threads to permit the insertion of lease cords or rods. The leasing is done to maintain an orderly arrangement of the warp threads mainly to facilitate the tying of new warp threads to the ends of runningout warp threads. i

Various apparatuses are known wherein the comb consists of a row of evenly spaced dents or needles each having a projecting hook on one side, while the other side is plain. These combs are arranged to be moved laterally in such a manner that previously inserted threads of a number of warps will, when being raised by means of breaker rods, either be engaged by the hooks or pass unhindered along the plain side of the needles. In this way a lease will be formed to permit the insertion of a lease rod, fixing the warps in a crossed relationship.

These known combs have the disadvantage of being selective by means of the lateral movement. This movement demands that the comb be exactly as broad as the warp. If this is not so the threads will not run parallel from the beam through the comb and out again to the slasher, or any other part of the weaving aggregate, with the result that the lateral movement of the comb ceases to have any selective effect on threads which enter it at an angle. In such an apparatus there must be as many combs as there are different warp sizes.

The present invention permits the employment of one comb for all warp sizes, because instead of moving the whole comb, it is the dents which are moved, since these can be made to turn around their axis to change the position of the projecting hooks in relation to the direction of the warp threads. This novel comb will be more readily understood from the following description taken in connection with the accompanying schematic drawings, in which:

FIG. 1 is an end view of the improved comb showing it between two beams;

FIG. 2 is a top view of what is shown in FIG. 1, and showing the hooks on the dents extending parallel with the warp;

FIG. 3 is a detail section on line IIIIII in FIG. 1;

FIG. 4 is a view similar to FIG. 2 showing the hooks extending across the interstices between the dents;

FIG. 5 is a detail section on line V-V in FIG. 4;

FIG. 6 is a view similar to FIG. 1 showing a modified form of comb;

FIG. 7 is a top view of FIG. 6;

FIG. 8 is a detail section on line VHI-VIII in FIG. 6;

FIG. 9 is a side elevation of a lease;

FIG. 10 is a detail view of a portion of a comb showing a few of the teeth or dents in front elevation with downwardly inclined hooks extending crosswise of the warp; and

FIG. 11 is a view similar to FIG. 10 showing the dents with curved hooks.

Referring now to the drawing, a warp 1 is shown drawn in full lines, and a warp 2 in broken lines. These warps 1 and 2 come from beams 3 and 4 respectively, and pass 7 3,164,883 Patented Jan. 12, 1965 ICC sidewise projecting straight hooks 10. When dents 6 are turned so that the hooks'lil project parallel with the warp threads (as shown in FIGS. 2 and 3) the warp 2 can be raised by means of breaker rod 8 to the position 2' shown in FIGS. 1 and 6. When the dents 6 are turned about their axis so that the hooks 10 project across the warp threads (FIGS. 1, 4 and 5), the warp 1 can be raised by the breaker rod 9 to the position 1' in FIGS. 1 and 6, and as warp 1 is raised it will be caught by the hooks 10. In that manner a shed or opening is formed through which a leasing cord or rod 12 can be inserted to fix the first half of the lease. Thereafter the dents 6 are turned so that their books again project parallel with the warp threads, and then warps 1 and 2 are lowered into their initial positions. At that time warp 1 can be raised by means of the breaker rod 9 without interference from the hooks 10. Thereafter the dents 6 are turned so that their hooks project across the warp so that they will catch the threads of warp 2 when it is raised by means of breaker rod 8. In this manner a second opening is formed through which a leasing cord or rod 11 (shown in FIG. 9) can be inserted fixing the complete lease.

It is understood that hooks 10 are sufliciently embracing to ensure that all threads are caught when this is desired. This is especially important if more than two warps are to be leased. It will be noted that in FIGS. 5 and 8, the hooks 10 extend entirely across the interstices between the adjoining dents and also crosswise of the threads. Hence no thread can escape being caught by a hook. The shape of hooks 13 may be varied as shown in-FIGS. 5, 10 and 11. In FIG. 5 they are shown as being straight and'having a slight downward inclination. In FIG. 10 they are shown as being curved in a downward direction. In FIG. 11 they are shown as curving out, down and in again. The threads of warps 14 and 16 are raised above hooks 13 while threads of warps 15 and 17 are caught by hooks 13.

To facilitate turning of the dents 6 these may be furnished with cranks 18 which are engaged by a ruler or connecting rod 19 to be moved simultaneously. As shown in FIG. 1 the dents have their lower portions extending through and rotatable in the comb body 5 with their projecting lower ends bent at right angles to form the crank arms 18, and the ends of the latter are bent upwardly at right angles and pivotally mounted in the connecting rod or bar 19.

In case of an uneven number of warps it is of advantage to be able to turn every second needle or dent 6 simultaneously. This may be done by employing two rulers connecting rods 20 and 21 as shown in FIGS. 6 and 7.

It will be seenthat by mounting a row of upright dents for axial turning on a support such as the body of a comb, by providing the dents with endwise projecting hooks and by connecting either all of the dents or groups of them for simultaneous axial turning, the connected dents may be moved to either of two positions, in one of which the hooks are disposed parallel with the warp and in the other position crosswise of the warp; and hence the device may be used for forming leases without any movement of the comb or other support and with very little move ment of the threads of the warp either vertically or horizontally. Thus the use of the invention overcomes many of the disadvantages of prior devices used for forming leases.

We claim:

1. A warp leasing device comprising in combination a supporting body, a row of upright dents, means mount ing said dents on said body for axial turning movement and in spaced relation to provide dentspaces through which the warp threads may extend, a sidewise project ing hook on each of said dents, and dent operating 3 means including at least one movable member operatively connecting at least some of said dents for simultaneous turning movement from one position, in which the hooks of the moved dents extend in a direction parallel to the warps, to another position in which such hooks extend in a direction crosswise of the warps, whereby the use of the device permits the warps to be crossed to form two openings for the insertion of two lease members therein.

2. The device of claim 1 in which said movable member of the dent operating means connects all of said dents for simultaneous turning movement, so that in said one position the hooks of all of the dents will extend parallel to the warps and in the other position the hooks of all of the dents will extend crosswise of the warps.

3. The device of claim 1 in which said dent operating means includes two of said movable members, one member being operatively connected to every other dent in the said row and the other member being operatively connected to the remaining dents.

4. The device of claim 1 in which each of said sidewise projecting hooks on the dents curves outwardly and downwardly from the side of the dent and then inwardly toward the dent, to provide space for a plurality of warp threads.

5. The device of claim 1 in which said dent operating means includes crank arms projecting from the dents, and said movable member is a connecting rod that connects the crank arms on those dents which are to be simultaneously turned.

6. The device of claim 1 in which said dent operating means includes two of said movable members and an outwardly projecting crank arm on each of said dents, the crank arms on every other dent in said row being operatively connected to one of said members for simultaneous movement and the cranks on the remaining dents being operatively connected to the other of said members.

7. A warp leasing device comprising in combination a comb having a horizontally disposed elongated body, a row of upright dents disposed along said body and having their lower portions extending through and axially rotatable in said body, said dents being spaced from each other to provide dent spaces through which the warp threads may extend, a sidewise projecting hook on the upper portion of each of said dents, a crank arm on the projecting lower end of each of said dents, and a movable connecting rod to which all of said crank arms are pivotally connected, whereby when said rod is moved to one position the hooks on said dents may be disposed in a direction parallel to the warps and when moved to another position the hooks will be disposed crosswise of the warps.

8. In a warp leasing device, a horizontal support, a row of spaced upright dents arranged along said support and each having a sidewise projecting hook, means mounting said dents on said support for axial turning movement, and means for simultaneously turning said dents and keeping their hooks projecting in the same direction.
