6 Claims.

This invention relates to a section warp beam', spool or reel of the type used for winding yarn prior to its winding upon a loom warp beam or for other uses. 1

In the use of section warp beams, spools or reels of the type to which this invention refers the development of theV trade is in the direction of rotation of the section warp beams, spools or reels at a higher rate of speed, and dynamic balance is required in order that they may be roo tated at such greater rates of speed. Also there is the growing use in the trade of so-called synthetic yarns such as rayon, celanese, bemberg and the like and it is found that these yarns cause greater strains upon the beams, spools, or reels than do cotton yarns. The strains are both greater compressive strains on the barrel and greater expanding strain on the heads. It is usual to use wood or fiber for the barrel of sections warp beams. The use of these synthetic materials upon such barrels compresses the barrel and in order that the barrelmay run true and in dynamic balance a chip must occasionally be taken from the surface of the barrel that the barrel may be maintained concentric and in such balance. Each time the barrel is trued it is weakened and the ultimate life is further diminished. One of thev objects of this invention is to provide a metallic barrel so trussed or supported that it may be thin and light in weightand yet will be oi such strength as to withstand the compressive strains of the yarn of synthetic-nature so that it will not become crushed or distorted but will maintain its dynamic balance for rapid rotation.

Another object of the invention is to so tie l together the metallic shell of the barrel and the central shaft through the barrel that the shell.-

central shaft and supporting means between the two will be substantially one homogeneous material.

With theseand other objects in view, the invention consists of certain novel features of construction, as will be more fully'descrlbed in, and'- Figure 3 is a fragmental sectional view on a larger scale illustrating the head vand the' means for its attachment to the barrel.

Figure V4 is a fragmental sectional view on a larger scale illustrating the relationship of the central shaft at its connection to the head.

Figure 10 is a section on line III-I0 in Figure 9.

Figure 11 is a sectional view of one of the supporting disks illustrated in Figure 8. j

Proceeding with this invention I provide a metallic shell of steel, light in weight and of cylindrical shape, and position within it a center shaft which I brace by securing supports betweenthe center shaft and the shell. These braces are welded into place so as to provide a substantially homogeneous structure.

With reference to the drawings in greater detai1,I have illustrated in Figure l a. metallic shell i5 of cylindrical shape and of a. desired length for the section warp beam which is provided. A center shaft |6 extends entirely through the shell. vDisks I'l having an opening to receivev the shaft'are of a size to extend between the shaftland the shell I5 and are welded as at I8 and I9 to the shaft and to the shell so as to provide va substantially homogeneous structure of these parts. These disks l1 are positioned at intervals along the barrel suiilciently close so as to obtain the desired supporting relation. The disks as well as the barrel are thin and light in weight secured as at 22 to the shaft I6 (see Figure 1) and A head unit designated generally 26 consists ofl an inner plate 21 and outerplate 28. The inner4 plate 21 is located substantially in a single plane with a flanged'edge 29 extending outwardly therefrom. The plate .23 serves as a reinforcing platev for the plate 21 and is dsilected'as best can be seen in Figure 1 so as to contact the plate 21 at the point 30 and extend outwardly at an angle to the plate 21 to engage the flange 29 along a portion 3|. While it extends outwardly as it approaches the center as at portion 32 to engage a hub 33 which serves to space the plate 28 from the plate 21 centrally of the head unit. Both

plates

21 and 28 are secured to this hub 33, the inner edge of the hub 33 being reduced as at 34 to receive the plate 21 against a shoulder 35 provided by its reduction in diameter. A strengthening .reinforcing annular member, 35, such as described in myco-pending application, Ser. No. 253,726, issued as Patent No. 2,263,113 Nov. l1, i941, in

ing the head to the barrel the outer plate 28 is deflected inwardly as at 31 a distance suillcient to form a recess 38 for the reception of the head of the securing means. Spacing element 39 isv positioned between the lower portion 40 of this recess and the plate 21 and is welded in position both to the plate 21 and the plate 28 at thi's deflected portion 4U. A bore 4| extends through this spacing element 39 and plate 21 so that a bolt 42 may extend through this hole and engage the threads of the hole in block 24. A lock washer 43 is positioned beneath the head 4l of the bolt while the head 44 is received in the recess 38 so as to be protected both from abrading any surface with which it may come in contact and from any jolt or bump which might serve to dislodge this means of connection from the head to the barrel or cause personal injury to the attendant. As seen in Figure 2 ilve of such connecting means all similar to the one described are provided.

-The center shaft I3 is reduced as at 45 so as to provide a shoulder 48 and the hub 33 of the head will engage this shoulder I6 solas to prevent the plates at this central 'location from cupping inwardly.

While I `have illustrated and described one means for trussing the barrel it might be desirable in some instances to provide the disks I 1 with a flange Il which provides for a greater welding area and also provides an axially extending support inwardly of the shell I5 of the barrel for greater strength and supporting relationship. The welding is performed along flange 5| of the edge oi' these disks and also is welded to the l shaft I3 as heretofore described.

In Figure 9 I have illustrated a still different or modii'ied form of strengthening construction for the barrel and here I provide annular rings 52 having a radially extending lip 53 and an axially extending lip il, the center l55 being cut away, and these rings are tied to the shaft' I8 by struts or braces '53 extending from one ring to the shaft and then returning to the next ring, as shown in Figure 9. A triangular bridge type of zigzag trussed construction is thus provided to securely brace the rings and shell against compression by utilizing a tie so that no axial movement of the shaft and the shell or the rings secured thereto may occur. Thus some of the tensile strength of the shell is utilized for support against compression in this type of structure. These braces Il are located radially of the barrel at three equally angular positions as shown in Figure 10 for the strengthening and support of the barrel in a relationship where great strength and minimum weight are necessary.

The ends of the barrels as shown in Figures 8 and 9 are the same as those shown in Figures 1-3 heretofore described and the heads may be positioned on these barrels as heretofore described.
