9 Giaims; (Cl. 28-43) The present invention relates to a leasing device for warping machines having a split rod frame for the split reds and a support for the lease reed.

-The device according to the invention is characternee by the fact that the splitrod frame is mounted on the lease reed support and in that the split rods are arranged immediately in front of the lease reed.

Thereby the split rod frame may be hinged tothe reed support so that it may be swung away from the lease reed to thereby displace a pair of guiding rolls in such a way towards each other that all ends passing through the lease reed are brought into one level or plane. In this position broken ends may readily be found and new ends drawn in. This position moreover forms the starting position for the so-called 1:1 end lease. To this end the lease reed may be displaced with respect to the split rod frame in a plane parallel to the plane of the split rod frame and inthe direction in which the teeth of the lease reed extend in order to vdivide in the usual manner the ends lying in one plane into two layers.

Preferably the splitrods are arranged in the split rod frame so that they can be lowered in common and lifted separately. For the multiple lease the distance separating two successive split rods may be enlarged, the thus formed larger interspace permitting an easy drawing-in of cords between two end layers. -Thereafter the split rods may be brought back into their starting position inwhich the successive split rods are equally spaced.

.There may be means providedfor imparting to the split rod frame during normal operation a constant oscillating movement in a plane parallel to the lease reed. Thereby it is prevented that the ends coming from the creel always .pass the lease reed at the same point which may lead to local wear of the reed.

Other features and advantages of the invention will become apparent from the description now to follow, of a preferred embodiment thereof, given'by way of example-only and in which reference will be made to the accompanying drawings, in which:

Referring to Figurel reference numeral 1 designates a support carrying a lease reed 2, the teeth 3 of which having upper and' lower abutments 4, 5 respectively. These abutments 4 and 5 in the interstices between the teeth 3 permit separation of the passing ends into corresponding layers. Guiding pins 6 project laterally the support 1 for slidably guiding the latter in grooves'7 of a. pair of guide bars 8. A traverseor cross bar 9 connects the two guide bars 8. The vertical displacement of support 1 on the pins 6 in the grooves 7 ofthe guide bars gis effected by cranks 10 and 11, positioned on both ends of the traverse 9 as is visible from Figure 2, and through a shaft 12 and toothed wheels Band 14, and racks 15 and 16 on support 1. A locking disc 17 mounted on shaft. 12 is engageable with a ball lock device 18 to secure the support 1 in any desired position; By means of the traverse 9 the leasing device is also connected with the warping slide 19 of a warping machine (not shown) and simultaneously it is supported by a pair of braces 59 and 60 on a carriage 61 displaceable on rolls 62 and .63 on the floor 64' immediately in front of the warping machine'and parallelly to. the longitudinal axis of the latter.

Figure 3 shows the actual leasing device and more particularly the mounting of the split rods 20-28 guided in a pair of side bars 29 and 3% having U-shapedcross sections and, as is visible from Figure 4a, held intheir relative position. To this end the outer tap diameter 31 of the split rods 21-27 increases from the lowermost split rod to the uppermost split rod so that these rods are maintained equally spaced from each other by a stepped fixing bar 32. A projection 33 formed on the fixing bar 32 bears on a cam 34, which may be operated through a shaft 35 from handles 36 and 37 arranged at both sides ofthe apparatus; If, as seen in Figure 4a, the cam 34 is rotated in a counterclockwise direction, the fixing bar 32 is lowered and displaced laterally-by the action of bolts 38, 39 of this bar guided in slots 40 and 41 respectively of the side bars 29 and 30, respectively. As a result of this movement of the fixing bar, the split rods 21-27, which are no longer supportedon the steps of this fixing bar, fall downwardly and gather but- 'on the lowermost split rod 28. This position is shown which the movable splitrods 21-27 maybe held in an,

upper gathered position. The meansiprovided to this end are visible in Figure 5b. In the latch bar 42 pawls 43 are arranged in such manner that they maybe pivoted in the direction'of arrow 92 but due to their asymmetric Patented May 31, 1950.

32, the latch bar 42 is also guided by bolts 47 and 48 f secured to itand guided in slots 49 and 50 of the side bars 29 and 30 respectively, so that the: latch bar effects a lateral movement resulting in the liberation of 'the movable split rods 21-27 from the pawls 43 so that-the split'rods may fall back into the arrangement'according to Figure 4a. Both cams 34 and 45 mountedon shaft 35 and serving to actuate the fixing bar 32 and the latch bar 42, respectively, are staggered with respectto each other so that upon lowering of the latch bar 42 the fixing bar 32 is already back in position to receive the split rods according to Figure 4a.

In order to bring the movable split rods 21-27 into the upper gathered arrangement according to Figure a, a lift bar 5-1 (Figure 3) is arranged laterally of the latch bar 42. As shown in Figure 6 this lift bar 51 may be lifted by a ball handle 52in slots 53 and 54. This movement is transmitted to a lift bar (not shown) in the side bar 30 by a rack 55, a gear 56 and a shaft 57. The split rods 21-27 are thereby separately engaged by a latch 58 at the taps 44, lifted and thereafter held in this lifted position by the pawl 43 (Figure 5b) associated with each split rod.

' Figure 7 shows in a side view the assembling of the lease reed support (Figure l) and of the split rod frame (Figure 3). In the guide rods 8 (Figure 2) there is formed a groove 65 opposite the groove 7. Two hinge levers 66 and 67 are guided in this groove 65 and are pivotally mounted in the side bars 29 and 30. Moreover the side bars 29 and 30 are pivotally mounted a distance in front of the lease reed braces 59 and 60 which is only a fraction of the thickness of side bars 29 and 30 as at 93 on .the carriage 61 by hinge supports 68. A pull spring 69 draws the whole split rod frame continuously against the lease reed support. By tilting about the pivotal point 93 on the carriage it is possible to pivot the split rod frame against the action of spring 69 from ;its position shown in full lines into the position shown in dot-and-dashlines. Thereby the two hinge levers 66 and 67 guided in the grooves 65 of the guide rods 8 are pivoted towards each other in a scissor-like movement. Guide rods 81, 82 are mounted on the hinge levers 66 and 67, respectively and these guide rods approach each other upon'the mentionedmovementof the hinge levers, that is when the split rod frame is pivoted outwardly as will be explained more in detail with reference to the Figures 811-80. According to Figure 8a the ends 70 are divided by a'creel (not shown) into a number of end layers 71-78 corresponding to the number of stages of the creel, passed through the lease reed 2 and through the guide reed, secured tothc warping cylinder 80 and wound up.

In order to form the so called 1 :1 end lease the described and illustrated device operates as follows: The split rod frame is pivoted away from the reed holder into the position shown in dot-and-dash lines in Figure 7. The relative movement of the guide rods 81 and 82 thereby produced brings the ends 70 on one level. If hereafter the lease reed 2 is upwardly displaced by actuation of the cranks or 11 (Figure 2), the ends 71, 73,, 75, and 77 are divided by the abutments Sand the ends;72, 74, 76, 78 by the frame of the lease reed 2 into two layers between which the first lease cord 83 may be inserted in a known manner (Figure 8b). Now the lease reed 2 is moved downwardly completely by means of the cranks 10 or 11 and'the same operation is repeated but with inverted ends 71, 73, 7 77 and 72, 74, 76, 78 respectively (Figure 8c). After inserting the second lease cord 84 the lease reed 2 is brought back into its starting position (Figure 8a) which simultaneously brings the guide rods 81, 82 again out of the end fields into the position shown in Figure. 8a. ,l-Ierewith the 1:1 end lease is terminated.

For the multiple lease, in which the ends 70, for example for the dressing, must be divided into several layers .the operator firstrotates oneof the handles 36m 37 (Figure 3) so'th'at the split rods 21-27 are lowered as shown in Figure 4b which results in the production of a larger space between the end layer 71 and the end layer 72 (Figure 9a). This larger space makes the insertion ofthe first lease or split cord 85 easy. Thereafter the split rod 21 (Figure 6) is raised by means of the lift bar 51 and the pawl 58 so that a larger space is now formed between the end layers 72 and 73, this second space permitting drawing-in of the second cord 86. This is repeated until all split rods 21-27 are in the upper gathered arrangement and all cords 87-91 have been drawn-in. By further'rotation of the handle 36 or 37 the latch bar 42 is displaced in the slots 49, 50 as described with reference to Figure 5a so that the "split rods 21-27 fall back into their starting position shown in Figure 8a. The multiple lease is herewith terminated.

If an end breakage occurs duringnormal warping the split rod frame is swung away from thelease reed support as shown in Figure 10 into the position shownin dot-and-dash line in Figure 7. Thereby the two guide rods 81 and 82 bring all ends on one leveland in this arrangement of the ends the point at which the new end must be drawn-in may be readily identified.

Preferably the split rods are removably arranged in the split rod frame. This facilitates the new drawingin of the end field and also makes it possible to position the lease reed and the guide reed on the creel with the ends drawn-in.

In order to avoid the situation in which, during the normal warping the ends always pass the lease reed at the same point, a movement may be imparted to the split rod frame parallel to the lease feed and perpendicular to the direction of the ends passing through the lease reed, for example by means of cams 62a and 63a driven by rollers 62, 63 and producing, during movement of the chariot 61 in front of the warping machine, an oscillating movement of the split rod frame with respect to the lease reed in thatthe cams act upon the displaceable pivot 93 of the split rod frame.
