WARP BEAM Filed Aug. 29, 1935 IN V EN TOR. v

Patented June 23, 1936 UNITED STATES PATENT OFFICE WARP BEAM Frank Mossberg, Attleboro, Mass., assignor to Mossberg Pressed Steel Corporation, a corporation of Massachusetts This invention relates to a warp beam and has for one Yof its objects the simplification of the construction of a warp beam and the provision of an opening extending substantially the entire length of the beam for securing the warps in position thereon by a batten or rod.

Another object of the invention is the spacing apart of the longitudinally-extending edges of the beam and the provision of supporting disks l0V which are shaped to cooperate with the spaced edges for the reception of a fastening rod or bar for locking the warps in position.

Another object of the invention is the utilizing of the end supporting disk for mounting a friction drum or pulley in position at the end of the beam.

Another object of the invention is the provision of an adjustable head with a disk and supporting hub extending from the outer surface of the disk and with outwardly-extending supporting ribs, the same being so formulated that the hub may be contracted about the barrel of the beam for holding it in the desired adjusted posi-v tion.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims..

In the formation ofA warp beams, it is sometimes desirable to simplify the structure; and in order that this may be accomplished I have formed a construction in which the edges of the barrely of the beam are spaced and the beam supported by 55 disks which are notched so that a batten when inserted between these spaced edges may be received in the notches of the disk and by reason of its width will bind a set of warp threads against one of the edges of the barrel to hold the warps secured thereto for winding them upon the beam, and I have utilized the end supporting disk for mounting a friction pulley and have also provided a head having a hub with supporting ribs, which hub even when so supported by ribs may be contracted upon the beam to secure the head in adjusted position; and the following is a detailed description of the present embodiment of this invention illustrating the preferred means by which these advantageous results may be accomplishedr- With reference to the drawing, I have shown the beam as composed of a barrel I0 which is rolled up from sheet stock with its edges I I and I2 spaced a certain desired distance, as illustrated in Fig. 2. This barrel is supported in this position by means of disks-l3 spaced at suitable distances along the body and welded to the inner surface of the barrel. Each disk is provided with a notch I4 which will have its opposite sides I5 substantially parallel and parallel to a perpendicular to a tangent to the outer surface of thev cylindrical barrel at the center of the recess I4. This notch is provided with a bottom I6 at right angles to the sides and the notch is of a width and depth sufficient to receive a batten or rod I'I winch is of such a size relative to the spaced edges I I and I2 asto bind the warps inserted into the space against one of the edges I I or I2 and securely hold a sheet of warps in position along the barrel. The notch I4, of course, in the disk limits the amount of insertion of the rod and thus prevents it from extending inwardly beyond the edges II or I2 that the gripping action may be lost at points between the disks.

In some instances, I may, however, provide a bottom wall I8 in the form of a strip or ribbon extending from one disk to another and located in the notches thereof against the bottom I6 to provide' a bottom wall for the opening or recess between theedges II and I2 for limiting the insertion of the rod and also providing a surface against which the warps may be bound, which structure I have illustrated in Figs. 6 and 7.

A friction pulley 20 .is mounted upon each end of the beam and is provided with a recess 2| of a size to fit the barrel I0 to center it with respect to the barrel and this friction pulley is secured in this positionby meansv of' bolts -22 extending thru a web portion 23 of the friction drum and into the tapped openings 24 in the end disk 25,

which securely binds the pulley in position on the end of the warp beam. Each of these pulleys is provided with a trunnion or spindle 26 supported in a hub 46 extending thru an opening 41 in the end disk 25 for suitably mounting the beam for rotation in any convenient bearings.

Adjustable heads designated generally 30 are mounted on the barrel, each of which consists of .a fiat disk 3| to which there is welded a. hub comprising a band or collar 32 having ,a flange 33 extending outwardly therefrom, which hub and flange are welded to the outer surface 34 of the disk 3|, while leaving the inner surface 35 perfectly smooth and clear for engagement with the warps. In order to better support this hub and also stiffen the disk 3| against warping or being l distorted from shape, I provide ribs 36 extending outwardly such as illustrated in Fig. 5. Each of these ribs is welded to the hub and flange and also to the outer surface 34 of the disk. This hub 32 is provided with a threaded nut 31 at one end and an inner threaded ear 38 at the other end while a bolt 39 extends thru the ear 38 and is in threaded engagement with the ear 31 to draw these ears together, turning of the bolt being accomplished by the polygonal head of the bolt.

In order, however, that the hub and flange may be contracted, I have provided a slot 45 extending from the opening between the ears 31 and 38 to ie point 4| to space the hub and iiange from the outer face 34 of the disk and I have carried this slot into the rib 42 outwardly as far as the dotted line 43 in order to permit this inner portion of the rib to flex with reference to the disk thus upon contraction by the bolt 39 that portion of the hub between the dotted line 4| and the ear 31 will iiex and the rib 42 will also flex to permit contraction of the warp for binding the head in position along the warp beam after the proper adjustment between the heads has been obtained. V

In Fig. 8, I have illustrated a still further modified construction of barrel and recess. A full channel 5G is positioned in the notches in the disks with its bottom wall 5| resting on the bottom |6 of the notches and with its side walls 52 positioned beneath the edges and |2 of the barrel. This channel may thus be held in without welding throughout its length or by welding only at its ends.

The foregoing description is directed solely ,towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being deiined and limited only by the terms of the append-V ed claims. v
