Description
Patented Nov. 28, 1933 FRAME FOR Looms John Szczerba, Amsterdam; N.. Y.,fassignoi' to Bigelow-Sanford Carpet Co:,-Inc.,- Thompson ville, Conn.,' a corporation'of Massachusetts 1 Application February 10, 1933. Serial No. 556,055 f This invention-relates to tube frames employed for weaving tuft pile fabrics such 'forfinstance' as' Axminster carpets and -rugs, and is more particularly directed to the yarn tubes throughwhich the pile forming yarn extends and by which it is presentedto the weaving 'point.
It is now the common practice to provide tube frames with yarn tubes extending therefrom and of generally ovoid shape in cross section. Such yarn tubes have heretofore been assembled on the carrier bar of the tube frame sideby side and each has been provided with a mouth or entrance end complete in itself for the yarn.
In weaving tuft pile fabrics of fine pitch it has been foundthat the dimensional area of' the mouth or entrance to the yarn tube frequently interferes with the free passage into the mouth and through the tubes of the pilevf'orming yarn.
especially when the latter offers any obstruction such as knots or other projections and frequently breakage of the pile forming yarn has resulted necessitating loom stoppage and repair. I 1
One of the objects of the invention is to provide yarn tubes which are not open to the oh- I jections heretofore existing and to so construct such tubes that the eflective area of the mouth or entranceof the yarntubes may be substantially and effectively increased, thereby permitting the ready passage of knots or other projec-'- extends from the spool '3 through the tu e-name 5" tions on the pile forming 'yarn'and adapting the tube frame for weaving tuft pile fabrics of finer pitch.
In accordance with the present invention each yarn tube is provided with only one side wall for defining the mouth or entrance to the yarn tubes while the other or oppositewall is constituted by a side wall of the next adjacent yarn tube. In
other words, the side walls forming the yarn tube are of different lengths, one extending the full length of the yarn tube while the other or shorter portion of the yarn tube terminates a substantial distance from the upper or entrance end of the yarn tube, the construction being such that when a series of yarn tubes thus constructed are assembled side by side the longer wall of the yarn tube forms one side of themouth or entrance while the longer wall of the next adjacent yarn tube forms the opposite wall of the entrance. I v g As a further feature of the invention the longer wall of each of the yarntubes is provided with a laterally extending portion or foot which serves as a means for securing the assembled yarn tubes in their assembled relation. Preferably a series of yarn tubes constructed as above ,connecting'it to the usual carrier chain 1 the warp threads.
outlined will be assembled on a backing strip-to 1 which they maybe secured by solder or other-;
wise, and then such 'a b'ack'ing strip'may beattubes in their assembledr'elationupon'a backing strip;
Fig. 3 is a'perspective view atthe rear of one of the yarn tubesdetached; i Fig. 4 shows theblank fro'm'f which the yarn tubes maybe;formed;'and
'Fig; 5 is a section'on the line 5 5 of Fig;-1'. I The tube frameindicated in- Fig. 1 may 'be of' usual construction/except as modified by the yarn" tubes of the presentiinventi'onand comprises the longitudinallyextending carrier'b'a'r 1 from which extendsupporting brackets 2 for the yarncarry-Q r ing spool or spools 3,' and elach of the tube frames of a set" isprovided with means forjdeta'chablyi;
As indicated in Fig; 1 the pile'forr'nin g" yam-{w 1 frame is taken to the weaving-point; as usual,
by the transferrer theprojecting endpo'rtionsof the pile forming yarn will be introducedi'betweeri Each yarntube 4 comprises a'tubular body 'por tion which as usual, may beovoi'd in cross sectionand at the top or entrance portion of the yarn tubethere is a head 5 ofs omewhat larger dimen sion thanthe tube. a V
One side wall 6 of the yarn tube extends bei yond the head and constitutes the longer side of the yarn tube, while theother side portion terminates at a point 7 a substantial distance from 1 9 the upper or mouth entrance end of the yarn tube, the result being that the two side walls 6 and 7 of each yarn tube are of different lengths and considered'separately the mouth or entrance end'f may be formed in convenient lengths and have tubular body portion of the yarn 9 'of course, restricted thereto. be folded :along the line 11 to provide a foot or "lateralextension 3 projecting from the longer side assembled thereon a desired number of the yarn tubes which may be secured to the backing'strip by solder or otherwise by means of the'la'terally extending portion or foot 8.
From the construction thus far described it will be apparent that each yarn tube is formed of a body portion of general ovoid cross sectional shape and an entrance or mouth portion having only one side wall, but when a series of such yarn tubes are assembled together, as indicated in Fig. 2, the side wall 6 of one yarn tube and the longer side 6, of the next adjacent yarn tube Referring to, 5 it will be seen at once that the dimensional area'jof the mouth or entrance ojtheyarn tube is definedby thelonger walls'of the two adjacent yarn tubes.- 7 I In Fig. 4 a blank is indicated from which th yarn tubes of the presentinvention maybe conveniently formed, althoughthe invention is not, The blank 10 may 6 of the yarn tube. The bends of the blank along the lines 1 2 a nd l3 form one portion of thetubu- 1 la-r body 4, while thebendsalong the lines 11 and .14 aiiord means for connecting the two edge portions of the blank to formthe completed tube, as
indicated in Fig. 3.
While it is preferred to secure or solder a seriesof yarn tubes ona relatively short backingstrip, as indicated in Fig; 2, it is apparent that the later-al extension 8 of the yarn tubes maybe connected directly to the carrier barl,
By forming the entrance or mouth portion of each. yarn tube cfa single side walland associating adjacent tubes, as shown, the effective area 'ofthe mouth entrance. is increased,- with the result that any knots or kinks which seek. to pass into and through'the yarn tubes will not be obstructed thereby, sothat breakage of the yarn will be avoided; and the assembling adapted for weaving tuft pile fabrics of finer pitch than heretofore.
