SECTION on WABPER BEAM 1 William McCaskie. New Bedford, Mass. Application July 8, 1946,, Serial No. 682,036

, 4 Claims.

. 1' This invention relates to a. section or warper beam upon which warp threads are to be wound. In the use of some of the synthetic threads such as nylon, contraction and expansion of the material on the beam causes great pressure upon the heads and sometimes a spacing of the head from the barrel sufliciently so that the yarn or thread will enter'the crevice between the two and I be jammed or held therein to such an extent that poor selvages may be formed due to the uneven unreeling of this stock from the beam.

One of the objects of this invention is to provide a structure by which the yarn or thread cannot become caught in the crevice between the beam and the head.

Another object of this invention is to provide a firm and strong beam and one in which the heads as well as the barrel are well supported.

Another object of this invention is to provide a structure in which it will be unnecessary to have a plurality of rods extending in grooves in the inner surface of the barrel from one head to the other.

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 drawings:

Fig. l is an elevation shown partly in section of a section or warper beam embodying my invention;

Fig. 2 is a section on line 2-2 of Fig. l

Fig. 3 is a section on line 3-3 of Fig. 1; and

Fig. 4 is a View of a modified construction.

In proceeding with this invention, I recess the head of the section beam and cause the barrel of the beam to extend into the recess so as to fit snugly therein. In order to support this head in position, a hub is secured within the barrel and bolts extend through the hub and head being reinforced by plates which are held on the outer surface of the head and abut the inner surface of the hub, the latter plate being so arranged as to engage grooves in the barrel to prevent relative rotation of the hub and the barrel.

With reference to the drawings, l designates one of a plurality of wooden staves which go to make up the barrel ll of the beam. Each of these staves is grooved on its inner surface as F at 62, which groove extends lengthwise throughout the length of the barrel. Heads designated generally I3 are provided at each end of the barrel and are made up of a plurality of plies I4, [5 and 16 of wood for strengthening the head. The inner surface l of this head is recessed as at llso as to receive the end of the barrel which fits snugly against the walls of the recess and the I head and barrel are held in this assembled relation by a structure now to be described.

A plurality of hubs i8 are positioned in the barrel at various points therealong. at which it may be desirable to provide a support for the bar'- rel'. and these hubs are held in position by screws or other metallic fastening means 19' which extend through the barrel and into the hub to hold the two in assembled relation. The end hub I8 is spaced from the head [3 by means of a collar 20 which surrounds a center shaft 2i which extends through the hub, head and collar. This collar is secured to the end hub l8 by screws or fastening means 22 and is secured to the shaft 2| by a screw 23. Threads 24 are provided on the outer end of the shaft 2| and a nut 25 engages these threads and will force the plate 26 on the outer surface of the head against the head to hold the head against the barrel.

The end hub I8 is also engaged by a spider plate 2'! which has a plurality of projections 28 extending outwardly from its main body portion so positioned as to engage the grooves l2 in the barrel staves and prevent this spider from rotating relative to the barrel. The spider is provided with a neck portion 29 which extends somewhat along the shaft 2| and screws 30 extend through this neck portion to engage the shaft and bind the spider plate thereto. Additional head attaching means consisting of a plurality of bolts 3| extend through the spider plate, hub, head and reinforcing plate 26 and are provided with heads 32 at one end and are threaded and provided with nuts 33 at the other end for additionally binding the head in position. These bolts are squared as at 34 where they pass through the spider plate 21 so as to prevent rotation of the bolt while the nut is being applied. The bolt as it passes through the hub I8 has a tight driven fit therewith. By this arrangement the head' I3 is firmly secured to the end of the barrel and as the recess is provided for the barrel to extend into the head, any slight relative movement of the head and barrel will not permit of yarn which is Wound on the barrel extending into a crevice thus formed to cause interference in its withdrawal from the beam.

In the modification shown in Fig. l, an annulus 35 is positioned adjacent hubs I8 so as to additionally strengthen the barrel ll so as to prevent its being deformed by contraction of the yarn wound thereon. The annulus 35 is of a size to be snugly received within the barrel and may be made of "Shelby tubing or a drop forging.

I claim:

1. A section beam comprising a barrel formed of a plurality of staves having grooves therein, a head at each end of the barrel, a hub, means to hold said hub within the barrel, a spider abutting the inner surface of the hub and having a plurality of projections extending into said grooves to interlock therewith, and bolts to bind the head and spider to the hub.

2. A section beam comprising a barrel formed of a plurality of staves, a head at each end of the barrel, each stave having a groove in its inner surface extending axially of the beam and a spider provided with projections extending into some of said grooves and secured to one of said heads to assist in holding the head in position.

3. A section beam as set forth in claim 2 wherein there is an axial shaft, a hub on said shaft,

a collar on said shaft to space said hub and head and means to draw the spider hub, collar and head together.

4. A section beam comprising a barrel formed of a plurality of staves, a head at each end of the barrel, each head having a recess in its inner surface and the end of the barrel extending into the recess, the walls of said recess closely fitting the surface of the barrel, an axial shaft extending through the barrel and heads, a plate on the outer surface of each head through which the shaft extends, threads on said shaft and nuts engaging said threads and said plates to hold the heads in position, and a hub in the barrel extending radially from the shaft to the inner surface of the barrel, means to secure the hub to the barrel, a collar spacing the hub from the head and engaging both and means to hold the collar on the shaft, a spider engaging the inner surface of the hub and bound to'the shaft and bolts extending through the spider, hub, head and plate to bind the whole together.
