Patented Sept. 24, 1940 UNITED STATES PATENT loFFlCE K v SLASHER I Homer H. Grier, New Holland, Ga. f Application September 23, 1939, Serial No. 296,245 Y 1l claim. l `(C1. fas-2s) 1 This invention relates to a Slasher and more especially toa particular arrangement of drying cylinders whereby yarn can be `more eiciently and speedily,vr treated. It is common practice in 5 textile manufacturing to apply a coating of size solution to the warpstrands so that the fibers will be consolidated thus giving added strength v 15.y prevents the breakingI of ends during a weaving ,It is a wellr known'fact that many mills have installed therein what is commonly known as normal two cylinder slashers. These machines were designed -for efficient work but in recent years they have often proved to be inadequate because their production is due primarily to the lack of drying surface which drys the yarn after it has passed through the size solution and before itis wound into a package.` Also these slashers have been installed in the mill as close as possible to each other, or to other textile machinery, so as to conserve space in the mill. In order to prevent the respacing of the machines and at thesame time to give theA necessary additional drying surface, an additional detachable drying cylinder-'must be provided at a convenient location, which will not ordinarily interfere with the other portions of .adjoining machinery.

It is therefore an object of this'invention to provide an addi-tional drying cylinder for the normal two cylinder Slasher in a position above the lease rods on the Slasher frama Where the conditions warrant, lit is preferable to suspend 40 this additional cylinder from the ceiling of the room in which the Slasher is located So that the supporting framework forthe same will notinterfere with the manipulation of the lease rods. and other operationsperfo-rmed in this vicinity k of the machine. u f l It is a further object of this invention to pro-` vide an additional cylinder above the leaseY rods of a normal two cylinder Slasher which is vdriven solely by the'frictional contact of the yarn passing thereover and whose horizontal projectionis disposed within the confines of the normal Slasher frame therebelow. By providing suitable antifriction bearings for this additional cylinder, the yarn can be caused to contact substantially the entire circumference of the cylinder thus insur-f.l

ing that the maximum drying surface will be utilized. Also by providing this additional cylin-,l der, the conventional Slashersfwhich are-nowin use can beremodeled so as to be equivalent to, or better-than, the latest up-to-da-te slashers. 5

` Some of the objects ofthe invention having been stated,v other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which-` Figure 1 is a sectional view througha room of 10 a building showing my improved slasher;

Figure 2 is a sectional viewtaken along the line 2-2 inFigure 1 Showing'Afthe additional drying cylinder;A y l Figure 3' is a view similar to the right-hand 15 portion' of Figure l, but showing the added cylinder Supported by Athe frameworkl ofthe Slasher instead of being Suspended from the ceiling as in the preceding form. Y v

Referring more specifically to the drawings, the 20 numeral ill denotes: the floor of a building having mounted thereon a creel frame I I in'which warp beams` l2 and I4 are rotatably mounted. From these beams a sheet -of warp threads |5` are drawn, `saidsheets being adapted to pass over 25 rollers I3 and which are rotatably mounted upon sizebox I8. This box has a. suitable size solution 1I9 therein in which immersionroller 20 rotates. Alsothe lower peripheries of .rollers 2| and 22 are submerged within the solution. After 30 the yarn leaves theroller itfpasses: beneath the immersion roller 20 andy over rollers 2| and 22 which apply the solution I9 to the sheet of yarn. Additional rollers 24 and 25ar`e mounted directly above rollers'2l and 22 respectively, and these'35 last-named rollers are adapted to squeeze the excess size. which has been applied to the sheet `with the size appliedto therwap sheet I5, it is V then'necessaryto dry the same, and also tofsep- 40 arater the individual ends from each other so that the yarn rwill bein condition for weaving or other uses. This drying processl is usually accomplished 'by Suitable drying cylinders such as designated end of a vertically disposed shaft 4I, said shaft 4I having another beveled gear 42 fixedly secured on its lower end which meshes with beveled gear 43 on positively driven shaft 40. It is therefore seen that, as the shaft rotates, both of the cylinders 28 and 29 will be caused to turn'in timed relation thereto.

The structure thus far described is conventional, and is well known in the textile art as being a normal two cylinder Slasher. The purpose of showing and describing this much of the old structure is to more clearly disclose the utility of the added structure which constitutes the invention.

The sheet of 'warp I5, after passing through the size box I8, passes upwardly over rollers and 46, and beneath roller 4I, these rollers being rotatably supported by a framework 48 at points slightly removed from the upper periphery of drying cylinder 28. After leaving the roller 4l, the warp I5 passes upwardly and around the cylinder 29 and then around cylinder 23, over a roller 4s, under a roller 5B and then upwardly in contact with 'rollers 5I and 52. The last named roller 52 is supported by a U-shaped framework 53 suspended from a ceiling 54. The warp I5 then passes around acylinder' 55, which likewise is supported by a framework 53, over a roller 56 and downwardly beneath a roller 51, after which it passes in a horizontal direction over and beneath lease rods 59, 60 and 5I which serve to separate the individual ends coming from the let oi beams, such as I2 and I4. The ends then pass through comb 62 which further serves to separate the ends 'coming from the individual beams from each other. When the ends have become properly separated, the warp sheet I5 passes over a roller B4, beneath roller 55 and over another roller 56, from whence it is wound around a take-up warpbeam 6l.

It is seen by observing Figure 1 that the added cylinder 55 is positioned directly above the lease rods 59, 60 and 6I and above the comb 62, but due to the fact that it is suspended from the ceiling 64, the operation of these lease rods and the comb is not affected. This arrangement gives the added heating surface, which is desired in modern machinery and serves to increase the production without an expensive outlay for new equipment.

Special attention is also called to the location of the rollers 45, 46 and 4l which serve to guide the warp sheet I5 in substantially a concentric manner about the cylinder 28 in its travel to the periphery of the cylinder 29. By keeping the sheet of yarn spaced closely to the cylinder 28, a certain amount of predrying is effected. This particular arrangement of the rollersalso makes it possible to cause the warp I5 to contact substantially all of the periphery of cylinder 219.`

In a similar manner the location of roller 49 causes the warp to Contact practically all of the periphery of the drying cylinder 2B. Similarly the rollers 52 and 56 are so positioned relative to each other and to the added cylinder 55 that its entire periphery is utilized. Therefore, it is seen that this improved Slasher not only makes it possible to have more heating surface on a normal two cylinder slasher at a minimum expense, but it also provides an arrangement of rollers whereby all of the drying surface will be utilized.

Attention is again called to the added cylinder 55. By referring to Figure 2 it is seen that this cylinder is rotatably mounted in uprights 'I5 which, in turn, are supported by the U-shaped members 53. As heretofore stated, this cylinder is mounted in anti-friction bearings such as designated bythe reference characters 15a. so that it` will be possible -to pass the yarn` around the cylinder and rotate it by frctional contact. This cylinder is normally heated by steam which is caused to enter the same by means of the intake pipe 'I1 and which is discharged from the cylinder by means of a pipe 18. From the discharge pipe the steam passes through trap members 'I9 and 89. At this point practically all of the steam has been condensed into a liquid.

Figure 3 shows a slightly modified form of the invention in which like reference characters will apply to corresponding parts which are shown in Figures 1 and 2. The chiefdifference in this form and thatl of the preceding form is vthe man-` ner yin which the added cylinder 55 is supported. lSometimes local conditions will not warrant y a suspension of the cylinder 55 from the ceiling of the building; consequently, other means must berprovided. In such cases an inverted U-shaped member 8l may be mounted upon the framework 30 of the slasher and upon this U'shaped frame-A work the uprights 'I5 and the addedvcylinder 55 are mounted. This type of mounting is desirable especially where the Slasher is to be constructed in a single self-contained unit.

rvrIn the drawings and specification, there has been set forth a preferred embodiment of the invention and although specific terms have been employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being set forth'in the appended claim.

A yarn Slasher having a size box at one end and atake-up beam at the other end, three drying cylinders located at progressively increasing heights beginning near the size box and terminating near the take-up beam end of the slaSher, a framework disposed `above the first cylinder and having three rollers therein the yarn being led above the first two of said rollers 'and beneath the third roller, for guiding the yarn from the size box over the first cylinder and out of contact therewith, the third roller being in close proximity to the periphery of the second cylinder for depositing' the yarn onto the second cylinder at a point substantially parallel with the axis of the second cylinder, `and thence almost around the first cylinder, means for guiding the yarn from the first cylinder at a point almost Ain perpendicular alinement with the point where the yarn first contacts the second cylinder'to the third cylinder, a pair of rollers in close proximity to each other and also in close proximity to the surface of the third cylinder for guiding the yarn to cause it to almost encircle the third cylinder, and means for then guiding the yarn from the third cylinder tol the take-up beam.
