9 Claims. (Cl. 242161) This invention relates to loom beams, which are employed to take up sized warp yarns issuin from a slasher and are sectionalized by means of separator discs, so that lengths of the yarns may be separately wound on the several sections of the beam. More particularly, the invention resides in a novel sectionalized loom beam which is so constructed that the warpmay be transferred from the top layer of a filled section to the bottom of an adjacent unfilled section without stopping the slasher or cutting the warp.

Sectionalized loom beams are used for test or experimental purposes in slashing operations, as, for example, when a section of the warp is to be cut out for sampling purposes, fOr determination of its moisture content, etc., or, when difierent sections of the warp are to be kept separate, bea cause the yarns therein differ in yarn number or fibre content or in' the size mixture applied thereto. Secti-onalized beams, as constructed heretofore, have commonly included single separator discs lying between adjacent sections, and, with such a beam, it is necessary to stop the slasher after each section is filled and then cut the warp, fasten the trailing end to keep it from dangling, and attach the leading end of the warp to the beam in the bottom of the next section before the slasher can be started again. The intermittent operation of the slasher and the necessity of performing the various operations described during each of its periods of rest are obviously objectionable but can not be avoided, so long as the prior beams are employed.

The present invention is directed to the provislon of a sectionalized loom beam, the use of which permits continuous operation of the slasher, until all sections of the beam are filled, and avoids the necessity of cutting the warp, etc., after the filling of a section is completed. The sections of the new beam are'separated by pairs of discs, which are spaced apart a short distance, and one of the discs of each pair is provided near its periphery with means by which the warp from a filled section of the beam may be directed into the space between the discs as the beam rotates. The other disc of each pair is provided with a slot leading inwardly from its outer edge to the level of the bottom of the adjacent beam section. With this construction, the warp from a iiilerl beam section may be caused to enter the space between the pair of discs at the end of the section and may pass therefrom through the slot into the next section to be wound, without stopping the rotation of the beam or interrupting the has been wound, the warp ends in each space between a pair of discs may be easily cut by a knife, and this makes the ends of the warp in the several sections available for placing in the loom.

For a better understanding of the invention, reference may be made to the accompanying drawing in which Fig, 1 is a view, partly in longitudinal section on the line l-l of Fig. 2, and partly in elevation, of a loom beamoembodying the invention;

Fig. 2 isa sectional view on the line 2-2 of Fig.

1; and

Fig. 3 is a fragmentary elevational view showing the use of the new beam. The sectionaliz'ed beam embodying the invention, which is illustrated in the drawing, includes a metal spindle or shaft I0, on which a pair of metal heads or flanges l l are mounted in spaced relation. A core or barrel is mounted on the spindle between the heads and, in the construction shown, the core is made up of a plurality of a similar members 12, which have the form of secoperation of the slasher. When the entire beam tions of a cylinder and may be made of wood or other suitable material. The core members have central bores through which the spindle passes and each member has a depression 13 in its surface. into the bottom of which is driven a screw i4. The heads of the screws serve as means for attaching the knotted end of the warp to each sectionof the core, although ordinarily the warp will be attached to an end section of the core only.

Adjacent core members I2 are separated by a pair of separate discs IS, IS which have openings for the passage of the spindle and are of a diameter substantially greater than the core members. The discs of each pair are kept apart by a spacer member ll, which is mounted on the spindle and is of the same diameter as the core members. The disc ii of each pair is provided at its periphery with means for engaging warp threads and, in the construction shown, such means take the form of a notch l8 having a radial trailing edge l8a and an edge l8b leadin at an angle from the lower end of edge 18a. The disc l6 of each pair has a narrow slot l9 leading inwardly from its periphery to the surface of the spacer member H. The slot may be radial, or at an angle to a radius of the disc IS. The

discs

15, 15 of each pair may be arranged with their re spective notch and slot in any desired arrangement, but preferably the notch and the entrance to the slot are angularly ofiset and the notches in the several discs 15 are aligned lengthwise of the beam, as are also the slots in discs l5.

The heads, core members, separator discs, and spacer members are assembled on the spindle in proper relation and then held in place by tie rods 20 passed through openingsthrough the hubs Ila of the discs and through the core members, discs, and spacer members.

In the use of thenew beam, it is mounted at the delivery end of the slasher and the ends of the warp to be wound are knotted together and attached to the screw l3 threaded into the core member in the first section of the beam at the left, as shown in Fig. 1, The beam is then rotated in the direction indicated by the arrow,

Fig. 2, until the warp has built up to form the mass 2|. The warp is then guided by hand or an appropriate mechanism into the notch I 8 in the disc l5 and is thence directed into the space -between disc l5 and the adjacent disc Hi. The.

warp is next guided through the slot, IS in disc IE to the bottom of the next section of the beam between disc l6 and the second disc IS. The winding continues until the second section of the beam is filled, whereupon the operations are repeated and the warp is led into the third section of the beam. After the several sections of the beam have been filled, the warp ends extending through the spaces between discs l5, l6 of a pair may be severed by a knife inserted between those discs and the warp ends in each section of the beam are thus made available for placing in the loom. 7

By the use of the new beam, it is possible, therefore, to wind a warp on the beam in sections without stopping the slasher after each section is filled, cutting the warp, and fastening the trailing end of the warp to prevent it from dangling, and then attaching the leading end of the warp to the next section of the beam. The new beam thus permits sectionalized winding of a. warp during a continuous slashing operation.
