H. M. CRAIG WARP DYE BEAM Oct. 24; 1939.

Filed July 24, 1957 INVENTOR. Hu BERT MCRR/G Patented Oct. 24, 1939 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to a perforated beam for dyeing and the like, and more especially to means for supporting a perforated cylindrical drum around which the yarn is placed prior to the dyeing operation. It is a standard practice to construct dye beams by providing a perforated cylindrical drum between two beam heads. The yarn is wound around this cylindrical, perforated portion, after which it is subjected to the dyeing l0 operation and to other liquid treatment. During this treatment the perforated portion is subjected to much pressure and therefore, it is necessary to properly reinforce this perforated cylinder on its interior so that the pressure will not cause 16 the same to buckle or collapse.

It is therefore, an object of this invention to provide a dye beam comprising a pair of heads between which is placed a perforated cylindrical member, said cylindrical member being supported on the interior portion thereof both longitudinally and axially, by struts and rings respectively. Both the struts and rings in the present instance, have contact with the interior periphery of the perforated cylinder thereby utilizing the entire intermediate framework between the two heads as a supporting means for the cylinder as well 'as giving added rigidity to the beam. Also, by providing a framework construction of this type, the longitudinal struts serve as spacer members for the head portionsand thereby carry the entire stress between the two heads so that the perforated cylindrical member will not be subjected to any compressive stress. This is very important since such stress, when carried by the cylindrical member, often results in buckling or warping of the drum, especially when it is subjected to the pressure during a dyeing operation. This construction is very important where stainless metal is employed for constructing the dye beam. In dyeing certain colors or shades, it is necessary to use a highly chemical resistant metal in order to avoid off-shades. Certain stainless metals, when subjected to temperatures necessary for welding, lose their stainless qualities. By providing the present type of construction, it is possible to eliminate welding and high temperature soldering, but at the same time, have a beam of the desired strength.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawing, in which:

Figure 1 is an elevation with portions thereof broken away, of a dye beam made in accordance with the invention;

Figure 2 is a top plan view of Figure 1 with portions thereof broken away;

Figure 3 is a sectional view taken along line 3-3 in Figure 1;

Figure 4 is a sectional view taken along line 5 4-4 in Figure 1;

Figure 5 is a sectional view taken along line 55 in Figure 2;

Figure 6 is an enlarged, detail view showing the intersection point of the rings which give 10 axial support to the perforated plates and the longitudinal struts which give longitudinal support thereto.

Referring more specifically to the drawing, the numeral Ill indicates suitable beam heads, each 18 of which have a hole I I in the central portion thereof, which hole is partially closed by a plurality of radially disposed spokes l2. At the intersection of the spokes l2, 3, hole I3 is provided which is penetrated by a suitable shaft, not 20 shown, when the beam is placed in an operative position. Each of the beam heads also has a hub portion I 4 in which rope grooves l5 are cut for accommodating a suitable rope by which tension is placed upon the beam.

The head portions ID are secured in spaced re lation to each other by suitable longitudinal struts l1. The ends of these struts are secured to the head portions ID by a standard gusset connection which comprises a pair of angles I8, 30 one angle being placed on each side of the ends of bars l1. Penetrating the upright legs of these angles I8 and the bar are bolts IS. The other legs of the angle I8 are adapted to fit against the proximate faces of beam head In and are secured 35 thereto by stud bolts 20. The bars I! are radially disposed about the hole l3 and the outer edges of the bars are adapted to support the interior surface of a cylindrical drum 25 which has perforations 25a therein. The bars l1 have at 40 spaced intervals along the outer edges thereof suitable notches 26, which notches accommodate rings 21, said rings having their peripheries normally contacting the interior periphery of the cylindrical, perforated cylinder 25. 4

It is thus seen that both of the struts I! and th rings 21, at their intersection, support the interior of the plate member or drum 25. This plate member has its ends embedded in annular cavities which are cut in the face of the head 50 members l0, (Fig. 5) however, it should be stated that this embedding of the ends of the perforated plate is made only for the purpose of eliminating a crack between the head portions l0 and the end of the plate. The beam is so de- 55 signed that the longitudinal struts carry the entire stress between the head members It, therefore no compressing stress will be placed upon the perforated cylinder 25. The ends of the perforated cylinder 25 have an additional support which comprises arcuate projections 29 which are integral with the face of head members I0 and which are disposed between the gusset connections for the bar H. The perforated cylinder 25 is adapted to support yarn which is placed therearound and when the same is desired to be dyed or subjected to other liquid treatment it is placed under pressure so that the dye stuff will flow through the yarn and through the perforations 25a in the cylinder.

It is thus seen that I have provided a dye beam having the perforated yarn supporting surface supported on the interior portion thereof both longitudinally and axially so that the lightest, strongest, and most economical design can be made without resorting to welding, brazing or soldering which is detrimental to the stainless properties of the material from which the beam is constructed.

In the drawing and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being set forth in the appended claims.
