TUBE FRAME FOR TUFTYWEAVING.
Applica'tiomfilbd .Tu'ly 2e, 1923. Seria1"No.*652,727.
This invention relates to tube'f-ramesused in weaving tufted fabrics such as Axminster carpets and isintended-to provide means for detachably securing the tuft tubes to the longitudinal carrier bar formlhps orf=flanges.5, by Wl'lLChithG carrier-bar ing' the back bone of the tube frame that will'preserve perfect alignment and parallelism of the tuft tubes against theordinary stresses of service, while making it possible to remove injured tubes and replace them with others without withdrawing the tube frame from the loom.
The present invention is particularly applicable for use in cases where it is-desired for special reasons to 'locate the tuft tubes with their intake ends positioned nearthe lower edge of thecarrier bar,- andyet not leave the delivery endsprojectingan unnecessary distance below' the lower edge or bottom of the bar.
A leading feature of the invention consists -in the combination with thelongitudi- 3; and P, which form part of, the interlocking connection by which the tuft (tubes; are ,detachablysecuredrto the carrier-bar.
nal carrier bar, of aseries-of parallel: tuft tubes detachably secured thereto by a telescopic' connection which allows :the tuft tubes to be attached or detached by sliding them longitudinally of the barninto or out of their proper positions "for use. These and other features will be explained :the following specification and: will vbeja-defined in the claims hereto annexed.
In the accompanying.drawings: I :have v illustrated different forms of construction and arrangement embodying the principles of this invention, in-which:
' Figure 1 is a front elevationshowlng :the
complete tube frame embodying Vmy" im-- provements with the middle portion broken away.
Figure 2 is a transverse section through In the practice of the invention, as 1llus-- trated in the drawingsglthe longitudinal can "rier bar 1,'=is made inhollow form of sheet metal and comprises a hollow truss or chan- -nel comprising a back wall 2, top-wall 3 and a bottom wall 4, adapted to be secureclzovei' the inwardly projecting verticalattaching is secured to thelhanger 6,:which; is:.pro
:vided with an upwardly extending chainengagingtongue 7, and a movable hook arm 8, cooperating therewith 'tosuspendxthe hanger from' the carrier chain :in: a rwell xknown manner. 'The yarn-spoolynot shown,
:the loom.
The main ielement or' channel of, the carrier bar has its top ,andobottomewalls bent back to form reversely turned lips Orfianges The individual tuft tubes 10 are soldered side by side in parallelism with their opposite ends aligned with one another to a suitable-holding strip12, whose opposite edges .are 'rever-sely bent to form ,-interlocking flanges l2 and 12", dimensioned to forma telescoping engagement with the icorre spondlng flanges 3, and 4,-of,the main elementor channel oftheearrier bar construction. I
In order to protect the iii-feeding yarn tufts from chafing against the fsharp rearward edges-of the intake openings of the tuft tubes, the:1nai1r body portion of the bar 12 has, its upper portion somewhatzoif set or, outwardly bulgechasshown, at 12, to
raise thisportion of its surfacebeyond the I level of the, adjacent back edges of the tuft tubes so that the yarn does notcomeiin contact with or scrape against the backedges of the tubes.
As shown in the drawings,the end of the tube-carrying elementor strip 12 may be formed with inwardly offset lipsoraflanges 12 which lap-under the adjacentwedge of 'the next unit or-section of the'tube-attachelement 12.
The main carrier bar element is: made zine tegral of the required length for the tube frame, but the tube-attaching members may be made-in shorter sections ot any desired length, and in such cases the short flanges 12 serve to preserve perfect alignment by forming a lapped oint between (llfiBl'GIll) adjacent sections.
In practice, the individual tuft tube units or sections are assembled by presenting them with their attaching plate in endwise alignment with the flanged edge portions 3 andl of the main carrier bar element, and are then slid along the main carrier bar element with which they have telescoping engagement until the requisite number of tuft tubes are assembled side by side on the carrier bar. To provide against endwise displacement the carrier bar 20, is made with integral top, bottom and back walls, the bottom wall having its forward edge reversely bent to form an attaching flange 20*, while the top wall is extended and carried over in a forward direction and has itsedge reversely infolded as at 20, thus leaving a gap be tween the edge of the integral front wall 20 and the front edge of the bottom wall to be bridged over by the tube-carrying and attaching strip 21. which has correspondingly turned lips or flanges 22 and 23 for slidingly interlocking or telescoping with the flanged edges of the carrier bar 20. The attaching strip 21 also may be provided with an inwardly offset lip 21 to lap under the adjacent edge of the next section.
hat I claim is:-
1. A tube frame for tuft weaving embracing in its construction a longitudinal carrier-bar, and a series of parallel tuft-tubes secured thereto to project transversely thereof by an interlocking, slidable, attaching connection which permits the assemblage of the tubes on the bar by a sliding movement longitudinally of the bar, substantially as described.
2. A tube frame for tuft weaving embrac ing' in its construction a longitudinal carrier-bar, and transversely disposed tuft-tubes secured to an attaching member, said member having interlocking attaching connection with said car'rierbar which permits its assemblage and removal by movement longitudinally of the bar, substantially as de-- scribed.
provided with longitudinal tube-attachinglips, a'series of parallel tuft tubes, a tubecarrying attaching strip constructed to be in'terlockingly engaged with said lips to detachably retain the tuft tubes in operation. position for service, substantially as de scribed.
5. A tube frame for tuft weaving, embracing in its construction a longitudinal carrier bar provided with longitudinal lips, a tube-attaching strip having cooperating lip-engaging members for. locking. them to said bar and a plurality of parallel tuft tubes secured to said strips, substantially as described. I
6. A tube frame for tuftweaving embracing in its construction a longitudinal carrier bar provided with longitudinal hooklike flanges, a tuft-tube attaching strip provided with hook-like members adapted to form interlocking engagement with said flanges, tuft tubes secured on said strip, and
means for anchoring said strip against longs tudinal displacement along the bar, substantially as described.
7. A. tube frame for tuft weaving, embracing in its construction a hollow carrier bar having an open side whose longitudinal edges are bent back to form retaining flanges, a tube-supporting strip WlIUSQlOlAgl" tudinal edges are formed to slidingly interlock with said flanges, and, a row of tuft tubes whose intake ends overlap one side of said strip andare secured thereto, an m hanging portion'of said strip being projected outwardly 'to protect the yarn from chafing against the rear edges of said tubes, sub stantially as described.
8. A carrier-bar for a tube frame embracing a hollow longitudinal bar and a longitudinal tube-carrying strip detachably se cured thereto by a retaining connection permitting the strip to be operatively assembled and to be released by movement lengthwhae of the bar, said strip being formed with a longitudinal offset for protecting the tuft yarns against chafing as they enter the tufttubes, substantially as described.
- In witness whereof, I have subscribedthe above specification.
