Application November 5, 1934, Serial No. 751,480
Claims. (01. 28-40) on the warp beam. Otherwise excessive wear and breakage of warp threads will occur as the' crossed threads approach the loom harnesses or reed dents.
For this reason, correct leasing of fine warp threads is very important, and it is the general object of my invention to provide an improved lease-forming mechanism by which the warp threads may be conveniently leased in correct and parallel weaving relation.
A further object of my invention is to provide effective means for taking a lease during theoperation of the maohine, and to provide conveniently operated manual devices for raising one or more banks of heddles and for simultaneously gr, depressing the remaining banks, and for thereafter reversely operating said banks.
Another feature of the invention relates to the operative relation of the lease forming mechanism to certain parts of the slasher on which it 39 is used. a
My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.
A preferred form of the invention is shown in the drawings, in which Fig. 1 is a side elevation of a slasher having my improved lease-forming mechanism embodied therein;
a Fig. 2 is an enlarged end elevation of the leaseforming mechanism;
Fig. 3 is a further enlarged side elevation of the manual operating device, looking in the direction of the arrow-3 in Fig. 2; a

Fig. 6 is a front elevation of my improved 50 lease-forming mechanism;
Fig. '7 is a plan View thereof, looking in the direction of the arrow 1 in Fig. 6;
Fig. 8 is a sectional side elevation, taken along the line 8-45 in Fig. 6, and
55 Figs; 9 and 10 are enlarged sectional side elevations similar to Fig. 8 but showing the parts in different operative relations.
In the drawings, I have shown a machine adapted for sizing and drying fine warp threads such as rayon and for delivering the same to a 5 loom warp; beam.
Referring to Fig. l I have indicated a frame 10 on which a plurality of section beams H may be conveniently mounted, preferably so that the sheets of threads from successive beams II will 10 be superposed as they approach the back comb i2 and size tank l3.
I have also shown the usual drying cylinders 14 and 15, from which the sized and dried thread passes around and between guide-rolls l5 and ll 15 to a plurality of separator rods 19 mounted in fixed brackets 28. At this stage the threads comprise what is termed a warp.
The warp threads then pass through my improved lease-forming mechanism, indicated gen 20 erally at M, and then through a front comb 22, over or between suitable guide-rolls 23 and around a cylinder 24 to the warp beam 25.
I will now describe the details of construction of the lease-forming mechanism M. This mech- .25 anism comprises a plurality of vertical heddles (Fig. 7) loosely mounted in separate banks on horizontal supporting bars or stringers 3i carried by harness frames 32 so that the planes of the heddles may be inclined to the direction of 30 travel of the threads therethrough as the heddles swing on the bars, as known in the art.
Each heddle 30 is provided with a much elongated slot 35 in its longitudinally central portion. The warp threads W pass freely through the slots 35 35 in the heddles 39 during the normal operation of the machine, as clearly shown in Fig. 8, and ample clearance is provided both above and below the threads, it being understood that each slot receives only one thread, as plainly shown in 40 Figure 8.
The harnesses 32 are preferably mounted on cords or straps 4t and 4! (Fig. 6) extending over guide-rolls 42 and 43. At theright of its guideroll 43 each cord or strap 40 is preferably secured 5 to the associated cord orstrap M, as indicated in Figs. 4 and 5, so that actuation'of the straps M causes simultaneous actuation of the straps 40.
The straps M are secured to a roll or shaft 45, and alternate straps M are preferably partially lapped around the roll 44 in opposite directions.
The roll 44 is mounted in a fixed bearing on a frame 48 (Fig. '7) and at its outer end is provided with a handle 5! by which the roll may be moved angularly in either direction, as indicated by the arrows a and b in Fig. 3.
The hub portion of the handle is preferably provided with an opening 52 (Fig. 3) through which a pin 53 may be manually inserted, after the handle 50 has been turned to bring the opening 52 into alignment with one or the other of two openings 54 in a depending portion of the frame 48.
Springs yieldingly draw the harness frame 32 downward, and the straps 40 and 4| are so adjusted that when the harnesses are at rest they will occupy the normal mid-position shown in Fig. 8, with the warp threads W passing freely through the slots 35, and with all of the heddles 30 at substantially the same elevation.
Having described the details of construction of my improved lease-forming mechanism, the -operation of said mechanism and of the machine to which it is applied is as follows:
The sheets of warp threads W from the different section beams H are assembled in superposed relation at the back comb I2 and thereafter pass through the size tank l3 and around the drying cylinders l4 and I5 to the guide-rolls l6 and H. The warp threads then pass over or under the separator rods I9 as indicated in Figs. 8, 9 and 10, and are thus separated into a plurality of superposed warp sections or sheets each preferably corresponding to one of the section beams l l Each section of warp threads is then drawn through the slots 35 of one bank of heddles 30, from which the warp threads pass through the front comb 22 in carefully arranged order corresponding to the drawing-in of the threads in the heddles 30. The comb 22 is preferably of the zigzag type, with a separate space for each warp thread, although when handling a warp of fine threads it will be understood that several threads may occupy a single space in the comb, as known in the art.
From the front comb 22 the warp threads W are drawn downward and around the cylinder 24 and are delivered to the warp beam 25.
During the normal operation of the machine, the heddles 3i) and harness frames 32 are positioned as indicated in Fig. 8, and the heddles are out of operative relation to the warp threads. If, however, it is desired to form a lease, the handle 50 is swung in one direction to raise certain harness frames and to depress the remaining harness frames to cause the ends of the slots in the heddles to engage the threads and raise and lower them, respectively, to form a shed as indicated in Fig. 9 in which shed the first and third harness frames and associated warp threads are raised, while the second and fourth harness frames are correspondingly depressed.
A lease rod, cord or tape 15 may be inserted in the shed thus formed, preferably in front of the front comb 22, after which the handle 50 may be swung in the opposite direction to form a second shed as indicated in Fig. 10, with the second and fourth harness frames raised and the first and third harness frames depressed.
A second leasing element 76 may then be inserted as indicated in Fig. 10, thus completing the forming of the lease. The pin 53 (Fig. 3) is preferably inserted in the holes 52 and 5A to lock the harness frames in raised or lowered position during the insertion of a leasing element.
After the lease has been thus formed and a few inches of warp has been drawn forward, a second pair of leasing elements 15 and 16 may be inserted, which second set is effective to hold the Warp threads in predetermined and correct relation to each other when secured to the barrel of a new warp beam after the warp has been severed between the two sets of leasing elements.
The above described lease-forming operation may be very quickly and easily performed and all of the threads will be correctly leased, if the drawing of the threads into the banks of heddles has been correctly performed.
The location of the mechanism M in front of the separator bars !9 is important, as the sized and dried threads have then been separated, and their position in sheets between the several bars facilitates the forming of the sheds.
Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:
