thread up tube frames not provided with like guards.

I attain the same result and to virtually the same extent as do these various guard devices, by strengthening the end yarn tubes of the units in the manner illustrated in the drawings so that they are capable of guarding the rest of the tubes on the unit or traine against accidental distortion or displacen'ieut; and without increasing the usual overall length of the yarn tube series.

Reference to the drawings, especially to Fig. lthereof, will disclose th-e manner in which I strengthen said end yarn tubes. The tubes TS, are made from pieces of metal of suitable gage and material out and formed into tubes of the desired shape which have a rearwardly projecting rib t2, the upper end T3 of which is bent at substantially a right angle thereto and is adapted to be secured to the underside of the tube bar A, or of the tube carrying angle I-I, to which tubes are frequently attached so as to form a yarn tube unit. The angle II, being adapted for secure attachment to the tube bar proper. By making and attaching the end yarn tubes substantially as shown and described, I provide satisfactory guards for the usual yarn tubes on the frame without making any change which will make necessary a change in the usual yarn tube threading devices which will interfere in any way with the proper handling of present tube frames which are not provided with my improved end tubes or other guards.

That I claim as my invention and desire to secure by Letters Patent is:

l. In a tube frame for an Axlninster loom, a tub-e bar; frame carrying chain 'engaging members attached at the ends of said tube bar; and a series of yarn tubes projecting` from said tube bar, the end tubes of said series having reinforcement and bracing parts so disposed that said end tub-es are capable of withstanding a greater force than will the rest of the series.

2. A tube bar for a tube frame for an AX- minster loom, comprising a single strip of metal formed into a hollow tube with a channel of substantialv depth in the 'top side thereof, the edges of said strip bent back upon themselves and joined together so as to form an interlocked bead; and end pieces attached inside of and closing` the major portion of the opening in the ends of said tube bar whereby the uuclosed portions ol" said openings form sockets adapted to re ceive and lit closely a tongue on the chain engaging en-d brackets.

3. A tube bar for a tube frame for an Axminster loom, comprising a single strip of metal formed into a hollow tube with a channel of substantial depth in the top side thereof, the edges of said strip turned back upon themselves and joined tog-ether so as to form an interlocked bead.

In a tuft yarn tube for an Axminster tube frame, a metal tube with a rearwardly projecting rib longitudinal thereon, a continuation of said rib projecting sideways therefrom.

5. In a tuft yarn tube for an Axminster tube frame', a metal tube with a rearwardly projecting rib longitudinal thereon, the rear of the upper part of said tube adapted to be secured to the face and the top of said rib to the bottom of the tube carrying member of the tube frame.

6. In a tube frame for an Axminster loom, the combination of a hollow metal tube bar, a clip secured to end of said tube leaving a spaced opening between the wall of said tube and said clip, a chain-engaging end bracket having a single horizontal arm adapted to enter said spaced opening.

7. A tuft yarn tube for a tube frai'i'ie for an AXminster loom, comprising a picee of sheet metal looped back upon itself, then closed together so as to form a. tube with a longitudinal projecting rib thereon, the up* per end of said rib bent sideways so as to lie at substantially right angles to the plane of said rib.

8. In a tubej frame for an Axminster loom, frame-carrying chain-engaging end brackets, and a one piece hollow tube bar of sheet metal with a channel formed in the top side thereof, said channel comprising spaced integral upstanding flanges and adapted to permit the use of tuft yarn spools of greater diameter by providing greater clearance without change in the relative location of the yarn tubes anid the spool center, said sheet metal bar having its longitudinal edges united intern'iediate the corner edges whereby to form a firm rigid hollow tube bar.

In testimony whereof I have atlixed my siginiture.
