TUrT-TUBErRAME FOB, WEAVING.
Application filed January 29, 1923.
1 '0 all whom it may concern.
Be it known that I, VALTER BIXBY, a citizen of the United States, and resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Tuft-Tube Frames for eaving of which the following is a specification.
This invention relates to tuft tube frames used in weaving Axminster carpets or similar pile fabrics and is intended to improve and cheapen the supporting structure or frame by which the yarn spool and tuftguiding spools are held in proper cooperative relation for service.
One feature of the invention consists in the novel construction and arrangement of the hollow carrier bar which forms the back bone of the tube frame, while other features relate to means by which such bar is con nected with suspension 'means for suspending it from the usual carrier chain, all of which will be set forth in detail in the following specification and will be defined in the claims annexed.
In the accompanying drawings I have illustrated some forms illustrative of the principles of this invention, in which:
Figure 1 is a front elevationshowing the complete tube frame embodying the features of this invention. I
Figure 2 is an enlarged rear elevation showing one end portion of the view with its suspension members.
Figure 3 is an end elevation of such tube frame.
Figure 4 is a cross section through the carrier bar showing how the individual tuft tubes are connected therewith.
Figure 5 shows in end elevation a modified construction of carrier bar.
I Figure 6 shows still another modification of the carrier bar construction.
Figure 7 is a perspective showing a. portion of the tube-holding member.
According to the form of the inv en'tionillustrated in Figures-l to 4,'the longitudinal carrier bar 2 is formed of a single strip of sheet metal which is bent or pressed'to form a tubular body of approximately polygonal cross section. the longitudinaledge portions 13 and 14 of the strip being projected from one side or corner of the tubular body to form a laterally projecting longitudinal Serial No. 615,514.
ledge to afford support for the individual tuft-guiding tubes 3.
For the suspension of the carrier bar and yarn spool I provide end brackets or sus pension arms 4, having an inwardly offset projecting ear 5, forming a bearing for the journal of the yarn spool 1, and an outwardly and upwardly projecting chain-engaging or penetrating member 6 which cooperates with a swinging hook arm 7 to releasably engage the carrier chain by which the tube frames are carried to and from position of transfer 'to the loom in the wellknown manner.
The. hook arm 7 terminates at its lower end in an eye 7 which is passed through an aperture in the lower portion of the suspension hanger 4, and is held pivotally in place by a fulcrum pin 9 passing through the eye and located inside-of the hanger. A spring 8, mounted in a pocket, exerts an outward thrust on the hook to make the hook operatively engage the chain until released therefrom by an opposing pressure.
The hanger covers the open end of the tubular body portion 2 of the carrier bar, and then is extended downward to or be- .yond the lower edge of the ledge 13, its lowerend portion being bent to horizontal position parallel with the longitudinal axis of the carrier bar with its extreme end or tip 11 bent upwardly to engage the bottom wall of the tubular body 2. The suspension arm at is also provided with an inwardly projectin'g plate or bracket 4* which telescopes inside the tubular body and through the top wall of the tubular body and said bracket Bis passed a fastening bolt whose lower end is tapped into the horizontal portion 10 of the suspension arm. In this way the suspension'arm is rigidly and firmly attached'to the end of'the carrier bar the lower .p'or-tion of said suspension arm forming a bracket or foot to rest on the transfer cani or shoe which transfers the tube frame at the propertime to the loom for the purpose of inserting the tufts in the fabric being weven. A spring arm 12, secured to the top of the carrier bar, acts as a brake to retard the rotation of the spool.
The individual tubes 3 may be securedto the carrier bar by any suitable means. In the form shown in Figures 1 and 4, I em ploy a tube-holding member 16, having parallel projecting flanges which are provided with corresponding tube-receiving apertures in registry with each other to afford support for the individual tubes at two different levels intermediate of their ends, the rear or intake ends of the tubes resting against a longitudinal bowed spring plate 17 to preserve a spring-holdmg tension against the rear ends of the tubes and form a guide for the tuft yarn as it unwinds from the spool and passes into the tubes. In this form the flanged holding member is a separate piece riveted or otherwise secured to the supporting ledge formed by the projecting ledges 13, 14 of the sheet metal forming the carrier bar.
Instead of forming the carrier bar from a single piece of sheet metal it may, for convenience in manufacture, as shown in Figure 5, be formed of two strips 2, and 2 with their inner or connecting edges rolled or folded together as at 2, while the flanges 13 and 14, as in the previously described form, overlap each other andproject laterally wi'th a row of rivets 15 uniting them to a tube-receiving and holding member 16. In this: case the tube 3, is slotted as shown at 3 to form a spring engagement with the edge of its surrounding aperture in the rearmost flange of the holding member 16. The infolded joint 2 may form a projecting rib forming a protective guide to prevent the yarn from scraping against the rearmost edge of the tube at the intake end thereof.
In Figure 6 the tubular body 20 is formed inone piece with its longitudinal edge portions 21 and 22 brought face to face and riveted together, but in that case each proj ecting edge portion is made sufficiently long to form projecting lips 23 and 24; which are apertured to permit the insertion of the individual tuft tubes in a manner similar to that indicated in Figure 4. In this case the carrier bar body and the tube-spacing and holding ribs or members are formed integrally with each other. 7
VVhatI claim is: I 1' v 1.
