ciaims. (ci. 24a- 124) This invention relates to a spool, reel or section beamhead, in which the head is made large in order that an increased amount of strand material may be wound upon the spool, reel, or beam, and has for one of its objects to provide means for strengthening the head in devices of this character.

Another object of the invention is to increase the strength of the head with very little additional weight.

Another object of the invention is to choose a location for strengthening of the head which will be extremely effective for the added weight Y supplied.

A further and more specific object of the invention is to locate the strengthening means at a greater radial distance from the axis of the barrel than the radius of the barrel.

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 accompanying drawing:

In the textile industry, the tendency has been to increase the diameter of the heads of section beams or the like in order to enable a greater length of warp to be warped onto the beam. The increase in the diameter of the head has created a problem for strengthening the head against the stresses which are exerted by the warp when the beam is filled with yarn which is especially important when the yarn is formed from synthetic fibers, such as is known as rayon or the like. If these heads do not remain true on a warp beam, difficulty is experienced in the warping of the ment is placed between the head plate and the reinforcing plate and at a location outwardly with reference to the position of the barrel that a very remarkable increase in strength is provided in the head in its resistance to stresses and this is accomplished with very little increase in weight of the head. Further, by utilization of this character of strengthening, I can very readily strengthen the head between the bolts which tie the heads to the barrel, the location between the bolts being the weakest part of the head, and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished:

With reference to the drawing, I0 designates a barrel of a section beam although it will be readily understood that this may be the barrel of a spool or reel so far as this inventionis concerned.

A head unit I I is secured to each end of the beam I0 by means of the tie rods I2 extending through channels I3 in the barrel and passing through the head units where they are secured by nuts I4 on the threaded ends of the rods. I have illustrated five of these tie rods I2 and it will be readily understood that any suitable number may be provided. Wooden discs I5, I6 are doweled in position in the barrel I0 and an axially extending shaft I'I is supported by these discs assisted by means of the bearing member I8. This rod is threaded along the portion which extends through the heads and is reduced to provide trunnion ends I9 for supporting the section beam for rotation in warping or drawing off the warps therefrom.

The heads II Iare each a unit construction which may be attached bodily to the barrel and the shaft I'I just above described. Each unit consists of a head plate 2l! arranged with its inner surface at right angles to the axis for contact with the work. The reinforcing plate 2| is bowed outwardly so that it contacts the plate 20 where it is welded as at 22 while it is spaced from the head plate 20 at its middle portion as at 23.

The head plate 20 is deflected outwardly as at 24 and provided with a central opening in which fits a bushing 25 having a flange 26 beneath which there are washers 21 to assist in supporting the same. The bushing is Welded to the head plate around the opening in portion 24 and also welded to the reinforcing plate. An opening 28 in the reinforcing plate 2i continues the openyarn. I have found that if a strengthening eleing formed by the bushing 25 and is of a size to slide over the axle I1. A nut 29 engages the threads 30 of the axle to abut the reinforcing plate and assist in holding the head securely against the edge of the barrel I and also assists in supporting the axle. Bosses 3l having openings through which the tie rods I2 extend are welded to the head plate 20 and extend through reinforcing plate 2| and are welded to this reinforcing plate, so that when the nuts I4 are threaded onto the ends ,of the tie rods they abut these bosses carried by the head unit and assist in holding the head unit against the edge of the barrel.

In order to further strengthen the plates of the head unit, I provide a strengthening element 35 which, as illustrated in Figs. 1 to 6, is annular in form. This strengthening element is located at a greater radial distance from the axis of the barrel than the radius of the barrel Ill or, in other words, it is positioned further outwardly from the center of the head than the surface of the barrel. This location is of importance as it is found that a greatly increased strength is acquired in such location which is not present if this strengthening element is not positioned outwardly beyond the radius ofthe barrel. This strengthening element is welded as at 3l annually to the head plate 20 on both its outer and inner circumference and is welded at intervals to the reinforcing plate 2I, such intervals of attachment being selected at locations 38 about midway between the attachment of the tie rods I2 to the head. This location serves to strengthen the head at the weakest point as it is between the tie rods that the head is most liable to be distorted because of stresses which are provided by the packageclyarn. These Welds as at 38 are provided by an opening 39 in the reinforcing plate and a filling of this opening with Welded material which attaches the annular strengthening element 35 to the reinforcing plate in a very the annular member 35, ribs 4I (see Figs. 4 andI 5) may be provided at the locations between thev tie bolts I4, these ribs extending radially either inwardly from or outwardly from the annular fined and limited only bythe terms of the appended claims.

I claim:

l. In a section beam, spool, reel or the like, a barrel, a head unit secured at intervals to the barrel, comprising a pair of plates with one overlying the other and so 'arranged as to provide a space between them, and a strengthening element contacting said plates and located in saidV space and having an inner radius greater than the outer radius of the barrel, said element being generally circular, radial reinforcing ribs located in said space between the points of attachment of said head unit to said barrel and contacting said element and of a size to engage both of said plates.

2. In a section beam, spool, reel or the like, a barrel, a head unit secured at intervals to the barrel comprising a pair of plates with one overlying the other and so arranged as to provide a space between them, and a strengthening element contacting said plates and located in said space at a distance from the barrel axis greater than the outer radius of the barrel, said element being generally circular, radial reinforcing ribs located in said space between the points of attachment of said head unit to said barrel and extending inwardly and outwardly from said element and of a size to engage both of said plates.

3. In a section beam, spool, reel or the like, a barrel, a head unit secured at intervals to the barrel, comprising a pair of plates with one overlying the other and so arranged as to pro- Vide a space between them, and a strengthening element contacting said plates and located in said space at a distance from the barrel axis greater than the outer radius of the barrel, said element being generally circular, radial reinforcing ribs located in said space between the points of attachment of said head unit to said barrel and extending outwardly from said element and of a size to engage both of said plates.

4. In a section beam, spool, reel or the like, a barrel, a head unit secured at intervals to the barrel, comprising a pair of plates with one overlying the other and so arranged as to provide a space between them, and a strengthening element contacting said plates and located in said strengthening element but preferably crossing the annular strengthening element as I have illustrated in Figs. 4, 5 and 8. This crossing is performed by notching the annular strengthening element as at 42 and also notching the ribs as at 43 causing the two parts to fit together and be welded as at 44 as shown in Fig. 8.

By the arrangement here shown, a head is provided in which the weight is but very slightly increased and yet the strength is increased about which is exceedingly important where heads are used of a large diameter. This arrangement enables the heads to be light and yet strong which is avery desirable feature.
