Application April 25, 1936, Serial No. 76,463

12 Claims. (Cl. 28-40) This invention relates to a machine for forming an end-and-end lease in warp, and in particular to a machine for forming a lease in Warp having a large number of ends per inch. The present invention involves improvements over the arrangement disclosed in my pending application Serial No. 16,250, filed April 13, 1935.

In my earlier filed application I have disclosed an arrangement for forming an end-and-end lease in warp having a large number of ends per inch, the arrangement involving a special reed construction in which each split or dent in the reed is provided with a plurality of spaced hook elements, and the warp to be leased is guided through the reed in four or more superposed vertically spaced sheets, with each reed space receiving an end from each sheet. Split rods (or parting bars) are suitably positioned to guide the sheets of warp through the reed so that two sheets are arranged between each pair of hooks. Suitable means is provided for shifting the reed both horizontally and vertically to selectively engage the ends of one or the other of the two sheets located immediately above each hook, and to carry the engaged ends vertically beyond the unhooked ends to form a shed between the hooked ends and the unhooked ends.

Broadly, the object of the present invention is to devise an arrangement to facilitate the operation of the leasing device disclosed in my prior application.

A specific object of the present invention is to provide a movable support for the split-rods which hold the warp sheets in vertically spaced relation, and to provide an arrangement for shifting the split-rod support along the bed of the machine to a point adjacent the reed when it is desired to shift the reed to engage the warp ends so the Warp ends will be accurately positioned with respect to the hooks on the reed, and, after the warp ends have been engaged, to quickly shift the split-rod support away from the reed to allow the reed to be moved vertically to form a shed in the warp. My invention also involves a method of manipulating the arrangement to form a lease.

A preferred embodiment of my invention is illustrated in the accompanying drawings, in which:

Figure 1 is a fragmentary view showing the essential elements of my invention in side elevation, with the split-rod support moved away from the reed support;

Figure 2 is a fragmentary side elevational view like Figure 1, except that the split-rod support has been moved into position adjacent the reed support;

Figure 3 is an enlarged fragmentary view taken along line 33 of Figure 1;

Figure 4 is a fragmentary side elevational view like Figure 1 showing the reed in elevated position to form a shed in the warp;

Figure 5 is a sectional view taken along line 55 of Figure 1; and

Figure 6 is an enlarged view showing certain details of construction of the split-rod support.

For the purpose of illustration, I shall describe my invention as applied to a slasher, but it will be understood that my lease forming machine may be used independently of a slasher, and in any situation Where it is desired to form an endand-end lease in warp. Referring to Figure 1. I indicates a section of the top side beam of the slasher frame located between the steam cylinder and the extensible comb on the slasher. A similar side-beam la. is located in the opposite side of the slasher as shown in Figure 5. The steam cylinder is not shown, but it is located to the right of Figure 1, and the extensible comb, the presser roll, the delivery roll and the warp beam are all located to the left of Figure 1 and are not shown.

The special hook reed for forming the lease is shown in end elevation at 2 and is mounted in vertical position transversely of the slasher frame. The details of construction of the reed 2 are given in my copending application above referred to and will not be described here. It will suffice to say that the reed is of the open-top type consisting of a plurality of splits supported from a rigid back, each split being provided with a plurality of hook elements spaced along the length thereof, and the hooks are arranged to engage warp ends bearing against the supporting split but will pass warp ends bearing against the adjacent split. Rigid end-bars are supported from the back and provide lateral support for the splits. In Figure 2, I have shown the end bar of the reed broken away to illustrate the spaced hooks 2a on one split of the reed.

The arrangement for shifting the reed transversely of the warp sheets consists of two vertical frames, one shiftable horizontally and the other mounted on the first and being shiftable vertically. The horizontally shiftable frame is formed of two end members 3 slidably mounted upon a cross-beam 4 supported between side beams I and la. The end members 3 are joined by horizontal rods (not shown) extending between these members transversely of the slasher frame. One

end member 3 is provided with a toothed rack 3a extending transversely of the side beam l, and the horizontally slidable frame is shiftable transversely of the slasher frame by means of a sector gear 5 engaging the rack 3d, the gear 5 being mounted upon a stub shaft 6 journaled in brackets T and 8 secured to the side beam l. The gear 5 is operated by lever B secured to the end of shaft 6. A short rod 312 secured to end-member 3 extends transverselyof the slasher frame and passes through a hole in a flange Set on bracket 8 with a slight clearance to permit sliding of the rod in the hole. A similar rod is provided at the other end of the frame for the lateralsllplwrt of I the frame and to maintain it in vertical position. The vertically shiftable frame is mounted to slide vertically within the horizontally slidable frame and is formed of two end members I0 joined by suitable horizontal rods (not shown) extending transversely of the slasher frame. One face of the end members i9 is provided with a gear rack at the upper end and the frame is raised and lowered by means: of spur gears (not shown) engaging these racks and mounted upon shaft H which may be rotated by the handwheel l2. The reed 2 is supported'from the vertically sliding frame by any suitable brackets engaging the end bars of the reed, such as brackets 83 and M. From the foregoing, it will be seen that the reed 2 may be moved vertically by operation of the handwheel l2 and horizontally by operation of the lever 9. My copending application above identified discloses an arrangement for operating the reed substantially like that disclosed herein and differing only in details of construction.

The split-rod support for vertically spacing the sheets of warp passing through the reed is shown to the right of the reed support in Figure 1. This support consists of two inverted gear racks l5 and l5a mounted longitudinally of the two sidebeams I and la (see Figures 1 and 5), and two base elements l6 and I611 having H-shaped sections (as' shown in Figure 5) are arranged to slide upon racks l5 and I511 respectively. A shaft at I1 is journal-ed in'the lower portion of base elements 5 and 5a and two spur gears l8 and, l8a located in the lower bifurcations of the two base members, respectively, and engaging the racks l5 and 15a, are secured to the shaft I7 and are driven by handwheel l9 mounted on one end of the shaft ll. Two horizontalshafts 20 and 2! are journaled in the upper portion of base members l5 and ltla. Two arms or standards 22 and 23 are secured to the shafts 2!] and 2! within the upper bifurcation of base member 16, and the lower ends of thse arms are provided with interengaging sector gears which cause the two arms to move symmetrically with respect to the vertical axis of the base 3. A similar pair of arms 22a and 23a are likewise secured to the other ends of shafts 20 and 2| within the upper bifurcation of the base member "5a. The shaft 2| is extended at one end beyond the base member I6 and is provided with an operating lever 24 by which the standards 22-23 and 22a23a may be moved into the vertical position shown in solid lines in Figure 1, or into an angular position shown in dotted lines in Figure 1 for the purpose to be described hereinafter. Suitable straps 25 and 25a may be provided for maintaining the standards in vertical position, but these straps are removed when it is desired to' open the standards.

Each of the standards on the split-rod support is provided witha-plurality of collar elements 26 which may be adjustably clamped in any desired position along the length thereof by means of set screws 2?, and each collar is provided with a transverse bore for receiving the reduced end of a parting bar or split-rod 28. By supporting the split-rods 28 transversely of the slasher frame by means of the Vertically adjustable collars 26, it is possible to quickly and easily adjust the vertical spacing between the sheets of warp passing through the slasher. By supporting half of the split rods from one standard andhalf from the other standard, it is possible to obtain a very,

slasher, the sheets of warp are first roughly positioned' in the split-rod support, each sheet being supported by an individual split rod. In order to accurately adjust the vertical spacing of the split-rods, the reed 2 is moved to its lowermost position and the split-rod support is moved into position adjacent the reed support as shown in Figure 2. The split-rods are then adjusted in position on the supporting standards so that two sheets of warp are located immediately above each row of hooks on the reed, as shown in Figure 2. It wil1 be seen that the ends of sheets A and B are positioned immediately'above the lowermost row of hooks, the ends of sheets 0 and D are positioned immediately above the second row and the ends of sheets E and F are positioned immediately above the third row of hooks. Ifadditional sheets are being run through the slasher they will be positioned in a like manner above the extra rows of hooks. When the warp sheets are arranged as described, it is possible, by shifting the reed horizontally and vertically to simultaneously select the ends of. either the odd numbered sheets or the even numbered sheets as desired, and, by shifting the reed so that the hooks will pass the unhooked ends, the hooked ends may be moved vertically beyond the unhooked ends to form a shed between the odd numbered sheets and the even numbered sheets.

The position of the split-rod support for the normal running of the slasher is shown in Figure 1, and where a small number of sheets are being passed through the slasher, the split-rod standards may remain in vertical position as shown in solid lines, but where a large number of sheets are employed, the split-rod standards may be opened up as shown in dotted lines in Figure 1 in order to relieve the tension on the warp sheets as they are being drawn through the slasher. If a large number of sheets are being used and the standards are allowed to remain in vertical position, the uppermost sheets would be subjected to greater tension than the lowermost sheets, but by opening the standards, the tension is more or less equalized.

When thewarp beam becomes full and is ready to doff, an end-and-end lease must be formed in the warp before the warp is cut. In order to form the lease, the reed'is moved to its lower- 'most position and the split-rod support is moved to the position adjacent the reed support shown in Figure 2. The reed is then manipulated to engage the ends of the odd numbered or the even numbered sheets, for example, the ends of the even numbered sheets B, D and F are engaged. The reed is then shifted so the unhooked ends bear against adjacent splitsand will pass the hooks. The split-rod support is then moved away from the reed support as shown in Figure 4, and the reed is then shifted to carry these sheets vertically upward and beyond the odd numbered sheets to a position shown in Figure 'A leasing bar 29 is then inserted Within the shed formed between the odd numbered sheets and even numbered sheets as shown in Figure 4. The leasing bar 29 is then moved to'a position adjacent the extensible comb and a leasing string is inserted in the shed in front of the comband the bar 29 is removed. In forming the second shed .of the. lease, the reed is returned to its lowermost position so that the warp sheets again occupy the normal running position shown in Figure l, and then the same series of operations are performed as described above for forming the first shed except that the ends of sheets A, C and E are engaged and are raised above sheets B, D and F. The leasing string is then returned through the second shed at the front of the comb and the end-and-end lease is complete.

From the foregoing, it will be seen that by providing a slidable support for the split rods, it is possible to accurately and quickly position the warp sheets with respect to the hooks on the leasing reed simply by moving the split-rod support to a position adjacent the reed support, and after the reed has been manipulated to engage the ends. of the desired sheets, the splitrod support is moved away from the reed support in order to allow the engaged ends to be raised to form a shed without subjecting the engaged ends to excessive tension.

Many modifications of my invention will be obvious to those skilled in the art. For example, the base members IS and Mia may be arranged to rest directly on the side frame members l and la and the racks I and |5a may be inverted and supported directly on the sidebeams. Also, by increasing the vertical separation of the hooks on the reed or by decreasing the size of the split-rods, all of the split-rods may be supported on one set of standards and the other set can be eliminated.
