Claims.

This invention relates to a warp dyeing beam head and more especially to a warp dyeing beam in which the flange portions on the proximate sides of the heads over which a perforated cylinder fits are cast integral with the heads and project a. substantial distance inwardly toward each other and have a plurality of bosses cast integral with the flanges and with the head, and the flanges being slotted longitudinally of the periphery thereof, so that not only will the ends of the perforated cylinder be amply supported, but also there will be a free flow of the treating solution such as dyeing fluid, bleaching fluid, and the like, through the flange and through the extreme ends of the perforated cylinder.

Warp beams are usually made with the heads from 28 to 32 inches in diameter and a perforated cylinder is usually from 8 inches in diameter to 24 inches in diameter. All of them are approximately 54% inches between the heads. These beams are for dyeing warps or for bleaching the warp threads wound on the beams and there is usually disposed on one of the beams about 400 pounds of yarn. This yarn is wound on the beams on a warper, the perforated beam cylinder riding down on the drum of the warper at the beginning of the winding operation. This drum on which the perforated cylinder rests is to A of an inch shorter than the inside length of the beam. By riding on the cylinder, the warper drum drives the beam and also gives the braking surface for stopping the cylinder if an end breaks down. By driving the beam from the warper drum, the heads are hanging down, supported only by the ends of the perforated beam cylinder. These perforated cylinders have their perforations usually of an inch in diameter on of an inch staggered centers but sometimes these perforations vary in size as well as in the manner of disposition. Perforations have to be all the way to the ends of the cylinder in order for the yarn to dye properly or to bleach properly in the portions where the cylinder joins the beam heads.

Heretofore, it has been common practice to make a shoulder about /2 inch high, that is, an annular shoulder around the inside surface of the beam head, and to assemble the cylinder over these annular projections or shoulders, and then suitable bolts or tie rods are passed through the beam head and in the space inside the perforated cylinder to thus hold the head and the cylinder in assembled relation. The perforated cylinders are usually made of stainless steel or some other non-corrosive material and are usually about of an inch thick. In the severe service to which these beamsare subjected, running at about 500 revolutions per minute on high speed warpers, and then suddenly stopping when an end breaks down, the heads being supported by the cylinder, there is a tendency to stretch the cylinder at the ends so that the heads become loose.

It is an object of this invention to provide a warp dyeing beam having a perforated cylinder and head members with the head members having cast integral therewith annular rim portions projecting toward each other and over which the ends of the perforated cylinder are adapted to fit, the annular shouldershaving integral therewith and integral with the heads certain supporting members for strengthening and supporting the rims and these rims are grooved peripherally down to the supporting bosses to thus allow a free flow of the treating fluid through the rims and through the perforations in the ends of the cylinders.

It is another object of this invention to provide a warp dyeing and bleaching beam comprising a pair of head members, cast from stainless steel preferably, and each of these head members has an annular rim on the inside surface thereof and over which a perforated cylinder is adapted to be fitted, said rim and head member having integral therewith a plurality of supporting members integral with the interior surface of the rim and the shoulders extending further inwardly than as has heretofore been the case to provide greater support for the ends of the perforated cylinder, and the annular shoulders having peripherally disposed grooves running entirely around the rim portions and down to the supporting bosses to thus allow. a free flow of treating fluid through the rim portions and through the perforations in the ends of the cylinders fitting over the rim portions.

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 drawings, in which Figure 1 is an elevation, with the central portion broken away, and showing one of the end portions in section of my improved warp beam;

Figure 2 is a reduced vertical sectional view taken along the line 2-2 in Figure 1;

Figure 3 is an isometric view looking at the inside surface of one of the head portions and with the perforated cylinder removed therefrom;

Figure 4 is a sectional detail view taken along the line 4-4 inFig'ure 2;

Figure 5 is an enlarged view similar to Figure 4 and showing the rim before the grooves are cut therein.

Referring more specifically to the drawings, the numeral It indicates the two head portions which are identical and these are preferably cast from stainless steel. Each head portion has integral therewith, and projecting from the inside surface thereof, an annular rim portion I l which has castlintegral therewith a plurality of reinforcing members or bosses l2. The middle portions of the heads have cross members I! and I thus providing a plurality of openings i5 through which the treating fluid may flow to the interior of the beam, or through which fluid may flow out of the openings if the direction of flow is reversed.

The central portions of the heads ill have suitable bores l'l through which supporting rods may be passed for holding the same. The heads also have a plurality of openings therethrough, through which may be passed bolts 20 for securing the heads inside the ends of a suitable cylinder 2|. After the heads and the annular portions H have been cast integral with each other, then one or more peripheral grooves or slots 22 are milled to completely penetrate the annular portion II, but which do not penetrate the reinforcing members or bosses i2. Then the annular portions II are inserted inside the ends of the cylinder 2| which has a plurality of perforations 24 through-' out its periphery and throughout its length.

The heads on their exterior surfaces have annular portions .25 which are usually employed for fitting over a suitable opening in a bleaching or dyeing operation. The bolts 20 extend longitudinally inside the cylinder 2| and have nuts 21 on their ends and whereby the heads are secured to the ends of the cylinder 2 I.

If desired, the annular portions or rims I I may be cast with the grooves 22 therein and thus dispense with milling or cutting the same after casting the head members.

In the drawings 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 defined in the claims.

I claim:

1. A warp dyeing beam comprising a pair of head members and a perforated cylinder having spaced perforations disposed throughout its length, each of the head members having an annular projection disposed on the inside surface thereof and over which the ends of the perforated cylinder are adapted to fit, the head members and annular projections having integral therewith a plurality of supporting bosses disposed on the in- 4 side of the annular projections and each annular projection having a peripheral groove extending therearound and extending therethrough but not through the supporting bosses integral with the annular projection and the head member.

2. A warp dye beam comprising a pair of head members, each having on the inside surface thereof an annular rim projecting inwardly toward each other and each rim having integral therewith supporting bosses which are also integral with the inside surface of the head member and being disposed on the inside surface of the annular rim, the annular rim having a peripheral groove cut entirely therethrough down to the bosses and extending entirely around the annular rim to provide a slot through which a treating fluid may pass, the annular rims fitting into the ends of the perforated cylinder.

3. A warp dye beam comprising a pair of head members and a perforated cylinder, the head members on their inside surfaces having annular rims extending therefrom with bosses cast integral with the rims and the head members on the inside of the rims, each rim having a plurality of peripheral slots extending entirely therearound and out entirely through the rim members down to the supporting bosses.

4. A warp dye beam comprising a pair of head members and a perforated cylinder, the head members on their inside surfaces having annular rims extending therefrom with bosses cast integral with the rims and the head members on the inside of the rims, each rim having a slot extending entirely therearound and extending through the rims down to the supporting bosses.

5. A warp dye beam comprising a pair of head members and a perforated cylinder, the head members on their inside surfaces having annular rims extending therefrom over which the ends of the cylinder are adapted to fit, a plurality of bosses cast integral with the rims and the head members on the inside of the rims, each rim having perforations extending therethrough and being disposed between the bosses.
