$93 I 3Z\ 6 31! III/I u B .B'SLOCOMBE M'FULTON mvsMToas Patented Jan. 10, 1950 UNITED STATES: PATENT OFFICE This invention relates to textile apparatus andparticularly to warp beams, and is especially concerned with warp beams provided with endflanges which are adjustable along the length oithe beam barrel so to varythe length of barrelon which theyarnis wound.

In one form of warp beam with adjustable flanges the barrel is iormed'with a screw thread extendin from the ends of the barrel towards the middle, and the flanges are mounted on bosses which are internally threadedso that'theycan be screwed along the length of the barrel to adjust the position of the flanges along the barreli Locking collars are provided on the barrel outside the'flanges, which are screwed up tightly against: the bosses when the'flangesare in the desiredposition so as toprevent accidental rotation of the flanges. This form of beam is very satisfactory in many respects but-is'open to' the disad vantage that the screw threads on the barrel of the beam are liable to bedamaged, particularly in the transport, handling and storage of the empty beams, when the flange of one beam is apt to strike against the barrel of another and to damage the unprotectedscrew threads thereof.

It is an object of 'the'present invention to provide a warp beam with adjustable flanges in whichthis disadvantage is overcome or very substantially reduced.

According to the present invention the flange of a warp beam is carried on the inner end of a long collar that fits over the end of the beam barrel, the beam barrel and part of" the bore of the collarbeing screw-threaded for the attachment and adjustment of the" collar and flange,

while apart (generally less than one half) of'the length of the boreadjacent'to the inner end of the-collar isleft plain. The plain part of the bore of the collar then-covers, in the outermost position of the flange, the screw threadsof the barrel that are engaged by the threads of the collar'in the innermost :position of the flange, and the threads onthe barrelare thereby protected against'damage. It is desirable'to provide locking means for preventing accidental rotationof theflange and collar on the barrel, and consequent disturbance of the adjustment ofthe flange position By the arrangement described above; anad justment of the flange equal in length tothe plain part oi the bore is availabie'without any exposure of the screw threads; The assembly may, however, be arranged to" give a somewhat greater adjustmentsince" it is permissible for a limited length of the-threaded part of the barrel 65 V to beexposedinsidetheiiange; Thread's exposed immediately insidetlie' flange are not likely to-be damagedby theflanges'of other beams; since the parts of the flange assembly lying outside the inner face of the flange, e. gisupporting;buttresses on the outside" of the flange-and the collar itself which carries the flange; preventthe edges of the flange from" coming into contact with the barrel of another" beam-close to the flange'thereof.

While the range of adjustment afforded by the invention is limited thisis not a serious disad vantage since it iseasy'flbyproviding a small number of'bariel's (ii-"different lengths to anew for" a wide range of distances between flanges; Moreover it would in" any case be hi'ghly incon venient either to" have a long overhang of idle barrel with no yarn thereon extending beyond the-side-frames of the loom; or'for'the sake of accommodating a longbarrel, tduse a wide'loom for weaving: a relatively narrow fabric; The complete beam in accordance with the present invention; withit's flange assembly at each end, is light in'st-i'ucture andis; moreover, particularly well adapted to be constructed wholly or to a large extentof'lightalloyl The adjustment of distances between flanges is quick and easy to' make and theflangesoi different diameters may be readily: exchanged for one? another.

While the collarand the? flange may be made in one piece, it i'sfmore convenient" in manufacture to make them astwopieces; a collar that is' internally screw-threaded over'the" whole or the greater" part of its length, and a bossed flange" having a bore which ispartly plain and adapted tefi't closely/round the'barrel of the'beam and partly enlarged and screw-threaded in order to" bescrewedf tightly over" one=end oi the" collar,

the 1 latter being provided with" external threads for this purpose. Ihe plain part of the bore' of" tiie'fiangeandc'ollar assembly a'sawhole is thus provided; whollyor in p'ar't; by the'bore of the flange'boss. I

Theouter' surfaceof' the collar may conven- 4 iently be'fonnegi as 'a ohaing'race or 'ruiile adapted to be engaged by'chains or ropes for controlling the beam let-oi! in'tlie usuarway'. The end of the collar may be closed (since the. end of the barrel'does not extend through it) and'arrange'd to receivea screwed pike or trunnionfor convenience in the transport and handling: of the beam. For'the" purpose of mounting the beam in the'loom a suitable" bearing'surface maybe provided onthe collar" outside the chaingrace' orruflie;

A convenient form of lockingmjeans' to pre-- ing torque during weaving should tend to drive the flanges inwards along the length of the 4 The flange member 1 comprises a boss IS, the bore of which (including the flange thickness) is about 3 long and fits closely over the barrel I for 2" of its length at I1. The remaining part I8 of the bore, 1 in length, is enlarged and screw threaded so as to be screwed tightly over the external threaded part II) of the collar 6. Four radial holes I9 are bored, threaded and countersunk through the boss I6 to correspond with the four holes I2 of the collar 6. The holes I9, I2 receive four locking screws 20 with counter-- sunk heads, the ends of which are adapted to beam,'against the'pressure of the yarn wound on the beam. In this way the strain 'on the locking means is partly balanced and, moreover, there is little tendency for the warp threads to be trapped against the flanges.

The barrel of the beam preferably consists engage with the flats 5 milled on the surface of thebeam barrel I. The screws 2% thus serve the double function of preventing the flange member I from turning on the collar 6, and the collar 6 from turning on the barrel I.

The flange "2I itself is in thickness and is provided with of a tube of light metal of, say, quarter-inch gauge, provided at intervals with slots to receive the tying-on knots of the warp. .The barrel may, however, be made of woodwith a screw-threaded metal sleeve fittedover each endto receive the flange assembly. The flange and collar may likewise be made of light alloy. Where, however, chains or metal brake-shoes are .to be used for controlling the beam let-off, it is preferable to make the collar either of cast malleable iron or of a light alloy on'which'a surface skin, of hard metal, such as ,chromium is deposited by spraying or by electro-chemical methods.

By way of example two forms of warp beam according to theinvention. will now be described in greaterdetail with referenceto the accompanying drawings in which- Figurel is'an elevation of one form of beam in which the right-hand end is shown in external view and the left-hand end in section, with its parts separated. Q.

.Figure 2 is an outside face view of the beam flange of a second form-of beam, and V Figure 3 is a section through a flange assembly incorporating thefflange shown in Figure 2.

Referring to Figure l, the beam comprises a barrel I in the form of'a light metaLtubefi" in diameter and A? '*in thickness slotted every 6f as at 2 to receive thetying-on knots of the warp. The barrel I is screw threaded at'both ends 3, 4 for a distance of 5%f', the threads at 3 being right-hand threadswhile the threads at 4 are left-hand threads. Into thescrew threads at the ends3, 4 are milled four flats 5 wide and 3 long,.parallel to the axis of the barrel I and extending to within'z h of the ends thereof.

-On each end of the barrel I is screwed a flange assembly consisting principally'of 'a. collar portion 6 and a flange portion 1. Thecollar 6 is 6" inoverall length and; its'outer surface is formed so as to constitutea bearing surface 8 1" wide for the mounting of the beam in a loom, a chaingrace or brake surface 9 2 'fwide and a threaded part I 1 wide; Four holes I2 are bored radially through the threaded part ID at. a distance of A" from the inner edge thereof. The bore of the collar .6 is screw threaded over the whole of its length'to match thescrew thread on the corresponding end of the beam barrel, I and is closed at the outer end of the collar by means of a disc I3 welded or otherwise secured to the collar. The disc [3 is centrallybored and threaded for the reception of a pike or. trunnion I4, which issecuredby means of a lock nut I disposed on the inner face of the disc I 3, and facilitates the handling of the beam and its lo-- cation during beaming. a

eight radial buttresses 22 extending from the edge of the flange 2I to the boss It, the buttresses being 1 in width'and l in depth at the boss 2 and 3 is adapted to be fitted to a beam barrel of the kind described with reference to Figure l and is somewhat lighter in construction than the assembly shown in Figure 1. It comprises, like that of Figure l, a flange member 25 and a collar 'member 26. The flange 28 ofthe flange member is only in thicknessbut is reinforced notonly by eight buttresses 29 but also by a finger ring 30 1" in depth and '7-;; in radius and by a further ring 3I about thick and deep at the separated by two flanges 36 bevelled to 45 and.

A2" in maximum width and thickness. Four holes 31 are bored at equal intervals round the threaded portion 35 to correspond with four holes 38 bored through thethickness of the boss 32 for the reception oflocking screws 39. tachable pike 49, secured by means of a locking nut 4| in the end plate 42 of the collar 26, is also provided. j V

Each ofthe beams described above has a flange adjustment of 3" at each end, the adjustment being capable of being made in steps each equal to A; of the pitch of the-screw threads on the barrel I. The screw threads are completely concealed for the first two inches of the adjustment and only one inch of thread is exposed when the flanges are in theirextreme outward position, the threads so exposed being nevertheless protected from damage by the. proximity of the flange. By the provision of four interchangeable barrels I of 48", 54", 60" and 66" length re spectively any width of warp from 36 to 60" can be accommodated.
