machines, and particularly to the thread carriers and the means for supporting and controlling the same. In Letters Patent No.

1,105,452, issued to me July 28, 1914, there is shown a form of thread carrier having a roller at its inner end and a roller at its outer end by which the carrier is supported at both its inner and its outer ends upon positlvely driven pairs of rollers mounted on a revolving frame. One of the principal objects of this invention is to eliminate the inner pair of supporting rollers altogether and the positive drive of the outer rollers, and to take the weight off the outer pair of supporting rollers which are used in the present invention merely to drive the thread carrier in its circular path about the machine. The roller at the inner end of the thread carrier in my new construction runs on the margin of a disk which is preferably rotary and travels in the opposite direction to the thread carrier and in the same direction as the strands whichare passed over and under the thread carriers.

These and other features of the invention will be hereinafter more fully described and particularly pointed out in the claims.

In the accompanying drawings which show one embodiment of the invention,

Figure 1 is a vertical section of such parts of a braiding machine as are necessary to illustrate the invention; v

Fig. 2 is a plan view, partly broken away, of certain of, the parts shown in Fig. and

Fig. 3 is an elevation of the outer end of one of the thread-mass carriers.

For a description of the general type of machine to which ble, reference may be had to the aforesald patent, and it will only be necessary in the present specification to describe such parts the mvention is app1icaof the machineas will serve to make clear a the novel features and their relation to the machine as a whole.

Referring to the drawings, 1 represents the frame of the machine, preferably made spider shaped and provided with a central hub 2 which supports a central tubular shaft 3, at the top of which the fabric is formed. The shaft 3 is surrounded by a sleeve 4, which is rotatable on the shaft 3 and has secured to it a bevel gear 5, which rotates on the upper face of the hub 21 The fabric passes down through the hollow shaft 3 to an idler roller 6 mounted on hub, 2, and thence passes to the take-up mechanism (not shown). A driving-shaft 7, journaled in bearing bracket 8, secured to a ring 9 which forms part-ofthe frame, is provided at its inner end with a pinion 10 which meshes with bevel gear 5. I

Upon sleeve 4, above the bevel gear 5, is the revolving frame 11 which supports the strand guides (not shown), and is revoluble on sleeve 4. The frame 11, which may be termed the main revolving frame, is provided with a bevel gear 12 on its under side engaging pinion 10. Thus the parts carried by frame 11, and those carried by sleeve 4, to which gear 5 is secured, are caused to revolve in opposite directions.

Above the frame 11, is a disk 13, fast to sleeve 4, to which are secured concentric annular rims 14, 15 and 16 connected by radial arms 17 the inner 14 being mounted on disk '13. In each of the segmental spaces between rims 15 and 16, there is journaled a pair of idler rollers 18 and 19 for driving. the thread carriers hereinafter described. The disk 13 with its rims and radial arms may be termed the roller frame.

Another disk 20 is mountedto revolve on hollow shaft 3 above sleeve 4. The disk 20 is provided with a bevel gear 21 on its under side and the disk 13 is provided with a bevel gear 22 on its upper side. Bevel pinions 23, mounted on a bracket 24 fixed to the hollow shaft 3., work between gears 21 and 22 causing the disk 20 to be rotated in the opposite direction to disk 13 and the thread carriers driven thereby, and in the same direction as the strand guides (not shown) mounted on the revolving frame 11.

Thus the disk 20 moves in'the same direction with the strands t and prevents rubbing and chafing of the strands, while the rollers 27 roll freely over the strands. For certain classes of work, and in small size machines it will be found possible to mount the disk 20 stationary on the shaft 3.-

A series of thread carriers 25, each carrying a cop or mass of thread 26, are mounted in the several segmental spaces between rims 1A and and arms 17. At the inner end of the frame of each thread carrier is a supporting roller 27 which rests on disk 20. At the outer end of the thread carrier frame are a pair of rollers 28, mounted in a horizontal plane and running in a groove 29 in frame 11. Said rollers 28 both support the outer end of the thread carrier and take the centrifugal thrust as the carriers revolve. Another roller 30, mounted in a vertical plane at the outer end of the thread carrier frame, extends between rollers 18 and 19 Q (Fig. 3). Thethre'ad carriers are driven fromsleeve 4, through disk 13, and rollers 18, 19, engaging rollers 30, said rollers permitting the strands from the strand guides to be passed under the carriers and above @the rollers 18, 19, as the strands are car'- rled over and under. the thread. carriers.

The weight of the outer ends of the thread carriers is not supported by the rollers 18,19,

but by rollers 28 runmng in groove 29, and the rollers 18, 19, ,merely drive the-thread carriers. The outer end of each thread car- 1 rier frame is also provided on its upper side with another roller 31, lying in a horizontal plane and running between the frame 11 and a downwardly extending flange 'or guard 40 ring 32 secured to frame 11. Roller 31 acts in conjunction with rollers 28 to resist centrifugal thrust and cooperates with guard ring 32 to prevent the thread carrier from being dislodged inwardly from its position.

The threads 25 from the thread mass 276, and the strands t which are passed over and under the thread carrier, all'extend to the bushing 33, at the top of the hollow shaft 3, where the fabric isformed. I claim: 7 e
