Patented Feb. 18, 1930 UNITED STATES JOHN BRANDWOOD, F SOUTI-IPORT, ENGLAND YARN BEAM Application filed January 15, 1926. Serial No. 81,561.

The treatment with dye or analogous liquors of yarns wound on beams by the passing of the said liquors through the yarns and through the body of the beam has great and commercially recognized advantages as to saving of time and cost, over the old method of skein dyeing analogous treatment; and also, when there is a suih'ciency of the yarn to be dyed, over the method of dyeing the yarn in cheeses or like packages and then winding upon a beam for subsequent handling. it often happens however that the quantity of yarn to be dealt with is not suflicient to fill a treatment beam of full size and is too great for economical handling by the cheese treatment methods. Skein dyeing is then resorted to, with the unavoidable disadvantage of the extra costs, entailed by that method over the beam treatment method.

The object of this present invention is to provide means whereby yarn in quantities less than that required to fill an ordinary full sized beam, for treatment thereon, may be wound as required and then dyed or otherwise treated in the same manner and by the same means as a full size beam. According to the said invention section beams are employed to any desirable number and of any desired width between flanges, with means for assembling a plurality of such section beams into a complete beam, and means ior ensuring that all fluids with which the yarns on the said section beams are to be treated shall pass through the yarns only in the treatment vessel.

A very convenient method of carrying the invention into effect will now'be described, it being understood that the details given may be varied without departing from the spirit of the invention.

In the drawings Figure 1 is an end elevation of a section beam showing the flange and a method of securing one type of yarn bearing surface within the end flanges;

Figure 2 is an elevation partly in section of the section beam shown in Figure 1;

Figure 3' is a sectional View showing the end flanges of adjacent section beams when placed together;

Figure 4 represents the extreme end flanges forming the flanges of a complete beam composed of a plurality of section'beams, showingthe means for converting the beam into a homogeneous whole for the purpose of handling and treatment;

Figure 5 is an elevation, partly in section of a full size beam composed of a plurality of section beams of varying widths; Figure 6 is an elevation (broken) partly in section section of a filler or dummy beam; and

Figure 7 is an elevation of an assembled beam consisting of a plurality of section beams one of which is a dummy section beam.

Referring to Figures 1 and 2, 6 are end flanges each of which as to its outer portionis composed of non-corrodible metal of convenient thickness, nickelor a nickel alloy may be used. The inner portion of each flange is composed of a ring of cast metal 7 having the strengthening arms 8, the central bore 9 for the reception of a shaft, circular bosses 1O bored for the reception of further shafts. The edge or" each ring is returned outwardly as at 11, thus forming an angle ring, and the outer peripheries of the rings so formed are slotted on a radius as at 12. Each slot 12 is of just sutficient width to allow of a strip of non-corrodible metal 13 to be pushed thereinto with a tight push fit. Intermediate of the end flanges is the supporting ring 14 which is slotted in a similar manner to the flange rings 7 to receive the metal strips 13. The supporting ring 14: is provided with the bosses 15' registering with the similar bosses 10 of the flange rings 7, and through these bosses on the flange rings and intermediate supporting ring are passed tubular shafts 16, which are threaded at their extremities to receive nuts 17. The ring 14 may be maintained in the position longitudinally of the beam in any convenient manner, for instance by means of set screws passing through bosses and engaging the tubular shatts. The outer flange portions 6 of nickel or the like, which are annular, have their inner peripheries returned as at 18, and the angle rings 7 are secured within these returned flanges 18 by the rivets 19.

It is essential, to ensure that when two sections are in place together, there should be no passage for fluids between adjacent flanges, as treatment by fluids under pressure is contemplated and all fluids must pass through the yarns only to the interior of the beam, or in the reverse direction, in the known manner of treating full sized beams of yarn. A convenient method of making a fluid tight joint is shown in Figure 3. One angle ring 7 of each section has the inner face of its peripheral flange 11 recessed as shown at 20, and the other angle ring 7 is recessed on the outer face of the peripheral flange as shown at 21. lVhen two section beams are placed together, therefore, a rabbet joint is formed which, the recesses being machined and faced up, will under pressure form a fluid tight joint.

Various sect-ion beams sufficient to form a complete beam length having been wound, these section beams-five various widths are shown in Figure 5are taken and a central shaft 22 Figure 5 is passed through the central bosses 9. Rods 23 of a non-corrodible metal such as Monel metal, are then passed through the tubular shafts 16 of the section beams, these rods being threaded at their extremities to receive the nuts 24, as seen in Figure 4. In this figure the metal strips 13 are omitted for clearness. By screwing up the nuts 24 therefore the adjacent flanges of section beams are pressed tightly together and the plurality of'section beams are for practical purposes transformed into a singi beam for handling and treatment in a treatment vessel, such as the kier described in the specification to United States Letters PatentNo. 1,174,662. It will be noted that owing to the form of the flange rings 7 the end flanges of the completed composite beam will always have a tubular boss to fit within a seating of a vessel such as that described in the prior specification just referred to, whilst it may be maintained in position by the screw also described in that specification, the central shaft 22 of course being removed.

The weight of yarn on each section beam is of course much less than the weight of yarn wound on a complete single unit full size beam, and it is considered unnecessary there fore to provide a strong cast iron or like backing for the nickel or like flange portions. Nevertheless where it is thought desirable such backings may be provided, as they will not come into contact with the yarns. Where the nickel or like outer flange portion only is employed, the periphery of such flange may be turned over as shown at 25 Figure 4, to present a greater surface for support of the edge when it is for instane rolled, to prevent distortion of the plane of the flange.

The section beams which go to form a complete composite beam need not be of equal widths between flanges. They may be of varying widths to receive a greater or smaller weight of yarn, as in Figure 5. Any overall widths or combination thereof, suitable to make up the length of a full sized beam may be adapted. here the length of a section beam makes it desirable, extra supporting rings may be provided between the flanges or the ring may be omitted. Two of these are shown in the section beam on the right of Figure 5; the next in position has one; whilst the remaining two sections being comparatively narrow, do not require these intermediate supports.

Any convenient and suitable means for winding section beams for the purpose of the invention may be employed, for instance the known sectional warping frame or the ordinary full beam warper. If the latter is employed the usual winding drum is removed and winding effected by means of the apparatus described in the specification of application for United States patent filed under Serial No. 32,513. By the latter method a number of sections may be wound simultaneously, when connected together. At those points where flanges and angle rings occur in the length of such a composite beam, the dents in the comb of the warping frame which are opposite to the said flanges and rings are of course left blank.

After treatment of the yarns, the composite beam may be handled in any desired manner, or the said beam disassembled for the handling of each section beam separately.

It is not-essential for the purposes of this invention that the yarn bearing surface of a section beam should be formed of strips of metal as shown in Figures 1, 2 and 5. The construction of a beam such as described in the specification to United States Letters Patent No. 1,125,803 may of course be followed, with the necessary modification where necessary as to the structure of the flanges.

In addition to the advantage of enabling various section beams to be wound with a less number of ends of yarn upon each than would be necessary to fill a full beam, with subsequent treatment of .a plurality of such section beams together, the invention can be employed for the purpose of treating a number of section beams which, in their total length when placed together as hereinbefore described, would fall short of the length of a complete and single unit beam. WVhere the number of section beams wound with yarn is not sufiicient to form, when such section beams are placed together, a complete beam of a sufficient length for treatment in a desired vessel as for instance the kier of United States Letters Patent 1,174,662, fillers or dummy sections may be employed to make up the necessary length, and a convenient form of such a filler or dummy is illustrated in Figure 6. In that figure, 26 is an angle ring which with the exception of the radial slots 12 may be of the same form and construction as the angle rings hereinbefore described and indicated at 7 in the drawings Figures 1, 2, 3 and l. The surface of the dummy beam is composed of an imperforate cylinder 27 of metal open at the ends and riveted to the angle rings as shown in Figure 6. The flanges 6 are omitted as being unnecessary but as shown in the Figure 6 the means for making a tight joint with an adjacent section beam flange are provided on the angle rings. The position of one such dummy section in its relation to the yarn bearing section beams, in a complete assembled beam, is shown in Figure 7.

By using more of these fillers therefore as may be required or only one of the length required the full length of a complete beam may be made up for treatment, whilst the imperforate surface of the cylinder 27 effectually prevents the passage of fluids other than through the yarns on the adjacent section beams when a filler or fillers is or are assembled with such section beams.

In the form of dummy beam illustrated tubular shafts 16 are provided as in the section beams for the passage of the tie rods 23 therethrough.
