LOOK FOR WEAVING CARPETS AND LIKE FABRICS.

Application filed March so, 1928, Serial No. 265,863, and in Great Britain April 30, 1927.

This invention is for improvements in or relating to lOOIns for weaving Axminster carpets and like tufted pile fabrics, in which looms the coloured yarns for forming the patterns in the fabric are wound on spools so arranged that the yarns from each spool,

or from a series of spools placed end to end,

' single tube or its equivalent, and for these tubes to be joined together side by side upon a frame in such a manner as to occupy a width equal to the width of the fabric. These tube carrier frames are attached at each end to endless carrier chains which are operated to bring each frame into position so that the tuft yarn threads may be'inserted as required.

If the tube carrier frames extend across the entire width of the fabric it is necessary, especially in looms of considerable width, that the frames should be'sufiiciently substantial to prevent irregularity or distortion, and the frames tend therefore to become unwieldy to handle, inconvenient for threading down the tuft yarn threads, and expensive to repair. If on the other hand a series of tube carrier framesof shorter length are used, then the consequent employment of intermediate carrier chains and supporting means therefor, together with the additional mechanism required for transferring the tuft yarns to the fabric, adds greatly to the difficulty of keeping the loom running consist ently.

The present invention consists'in the pros vision of a foundation case or frame of the full width required, attachableto the carrier chains on either side in usual manner, and in the provision of sectional tube carrier frames adapted for attachment to said foundation case or frame and each adapted to carry its own spool, the sectional tube and spool carrier frames being placed end to end so as to extend completely across the fabric.

In order that this invention may be clearly understood and readily carried into practice, reference may be had to the appended explanatory sheet of drawings, upon which 2-- Figure 1 is a front elevation of a tube carrier frame having the present improvements applied.

Figure 2 is a rear elevation of the same.

Figure 6 is a plan of a part of Figure 2.

F lgure 7 is a view corresponding to Figure 3, but showing the sectional tube carrier frame disassembled from the foundation case or frame.

Figure 8 is a sectional end elevation illustrating a slight modification. 4

Figure 9 is a similar View illustrating a further modification.

In a convenient embodiment of the invention, Figures 1 to 7, I provide a foundation case or frame a, preferably of plain angular cross section ofiering the maximum resistance to distortion 'or irregularity, to the ends of which foundation case or frame a are attached the brackets 12 having springs 0 or other means of holding the frame at each end in the endless chains generally used for this purpose.

Openingsor slots d are provided at longitudinally spaced intervals in one web of the foundation case or frame a to permit of sec-' tional tube carrier framese being hung or attached in suflicient number to make the full width required, two such sectional frames 6 being illustratedf Each sectional tube carrier frame 6 is provided with substantially fiat end plates f having terminal projections g, and having hook projections h at one edge, the terminal projections g having notches i and being adapted to pass through the aforesaid openings or slots d in the one Web of the angular foundation case or frame a, and the hook projections 11. being engageable with notches j in the edge of the other web of the angular foundation case or frame a, each end plate f, as thus assembled in relation to the angular foundation case or frame a, bearing upon a flexible tongue is carried internally by the foundation case or frame, and being engaged at its extremity by a blade spring l carried externally by the foundation case or frame so as to register with the aforesaid notch i in the end plate 7.

ontheinner face of each end late is pivotally mounted at m a latch a aving at its outer end a notch 0 which is engageable with the lip of the opening or slot (Z, and,

having at its inner end a channelled lip 77, which is operatively engaged by the outer extremity of a resilient press lever q pivotally mounted at r on the frames and fitted with a spring at 8. Each end plate 7' is also fitted on its inner face with an apertured spring blade 25, the spools a being removably mounted between opposite pairs of these blades 2?. The multiplicity of tubes carried by the sectional frames 6 are indicated at o.

It will be seen that the foundation ease or frame a is adapted to carry any desired number of the sectional tube carrier frames 6, and that these sectional frames 0, with the spools it carried thereby, are located end to end in correct position. for inserting the tuft yarns into the fabric. It will further be seen that the projections g, the openings or slots (Z, the hook projections 7:, the notches j, and the flexible tongues 7a, cooperate to grip and hold the sectional tube carrier frames 0 in such correct positions within the foundation case or frame a, in which positions the sectional frames 0 are locked by means of the spring-pressed latches a. It will still further be seen that when the sectional tube carrier frames 6 are required to be unshipped from the foundation case or frame a, the latches amay be. released by means of their press levers Q? to permit of individual detachment of thesections, this detachment being facilitated by means of the blade springs Z, which impart a reverse pressure through the notched projections g to the sectional tube carrier frames 6.

hen changing the sectional tube carrier frames 6 for others of the same or any other design of the same number of rows, the foundation cases or frames a need not be takenfrom the endless chains, but the same design can be built up again, or a new design built up, by the introduction of other sectional tube carrier frames mounted upon the foundation cases or frames in the order required. j a a The interlocking of thelsectional tube carrier frames 6 to the foundation case or frame a adds greatly to the rigidity of the frame as a whole, While thesectional parts are much easier to handle, more convenient for threading, and less costly to replace or to repair, than. are the forms of tube carrier frame hitherto in use.

In a modification, Figure 8,tl 1e individual detachment of the sectional tube carrier 'frames 6, instead of being facilitated by reverse spring pressure as hereinbefore described, may be facilitated by the action of a lever w, this lever being pivoted at an to the end plate I, in such a manner as to be pressed a ainst the foundation case or frame a by the releasing movement of the latch n,

In a further modification, Figure 9, the individual detachment of the sectionaltubc carrier frames 0 may alternatively be facilitated, on the releasing movement of the latch a, by engagei'nent of a cam projection 1 with a lip of the opening or slot (Z in the foundation case or frame a.
