BRAIDING-MACHIN E.

To all whom it may concern:

Be it known that I, Amman PETERSEN, a citizen of the United States, and resident of Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Braiding-Machines, of which the following is a specification.

This invention relates to rotary braiding machines, and particularly to braiding machines of the type having a main revolving frame Within which a series of thread carriers are revolved in the opposite direction by a revolving roller frame, the main revolving frame carrying strand guides for passing the strands over and under said thread carriers. The invention consists in the novel'features of construction hereinafter described and particularly pointed out in the claims. I

In the accompanying drawings which illustrate one embodiment of the invention, and show such parts only of the braiding machine as a whole as are necessary for an understanding of the novel features of the invention,

Figure 1 is a vertical section of a part of a braiding machine containing the invention;

Fig. 2 is a fragmentary view, partly in plan and partly in horizontal section, of a pair of rollers and friction wheels carried by the revolving roller frame; and V Fig. 3 is an end view of one of said rollers and the friction wheel secured thereto.

Referring to the drawings, 1 represents the frame of the machine, preferably made spider sha ed, and provided with a central hub 2 whic supports a central tubular shaft 3, at the top of which the fabric is formed.

The shaft 3 is' sur'rounded by a sleeve 4 which is rotatable on shaft 3 and has secured to it, by nieans of a set screw 6, a bevel gear 5 which rotates on the upperface of hub 2. Thebraide'd fabric passes down through the hollow shaft 3 to a takeup mechanism of usual construction (not shown). A driving shaft -7journaled in bracket 8, carried by the main frame, is provided at its inner en'd with a'pinion 10 Specification of Letters Patent.

which meshes with and drives the bevel gear 5.

Upon the sleeve 4. above the bevel gear 5 is a revolving frame 11 which supports the strand guides (not shown) in the usual way,

and is revoluble 0n 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 the pinion 10. Thus the frame 11. and the parts carried thereby are caused to revolve in opposite directions to the sleeve a and the parts carried thereby.

Above the frame 11 is a disk 13 fast on sleeve 4- and turning therewith, to which are secured concentric annular rims 14 and 15 connected by radial arms 16, the inner rim 14 being mounted on the disk 13. The disk 13 with its rim and radialarms may be termed the roller frame. In each of the segmental spaces between the rims 14 and 15 and the arms 16, there is journaled a pairof rollers for supporting and driving the thread carriers hereinafter described, each roller comprising an outer roller element 17 and an inner roller element 18 connected by a shaft 19 disposed radially of the roller frame and journaled at its ends in the rims 14 and 15.

A friction wheel 20 made of felt or other suitable compressible resilient material, is fixed to the outer side of each roller 17 so that it rotates therewith. Preferably said friction wheel is in the form of an annulus secured to the outer face of the roller 17 by means of a Washer or rin 21 secured to the roller 17 by screws 22. r aid annular friction Wheel 20 and said washer wheel 21, as herein shown, are fitted over the outside of a flange or rim 17 on the roller 17. Thus the friction wheels are readily removable and replaceable in case they become worn or damaged. A ledge or flange'23 is secured to the inner side of the upright portion 24 of the main revolving frame 11, and the friction wheels 20 run on said ledge 23 thereby rotating'the supporting and driving rollers 17-18.

A series of thread carriers 25, each adapted" to carry a cop or mass of'thread, are

mounted in the several segmental spares between the rims l4 and 15 and arms it), earh being supported and driven by one of the pairs of rollers on the roller fram At lhe inner end of each thread rarrirr L in; a roller 26 resting on a pair ol rollers lb, and at the outer end of each thread carrier is a roller QT r sling on the corresponding pair ol' outer rollers 17. Said thread rarriers may also have horimnially disposed rollers 28 which run in guideivzrvs 21.] on the main revolving l'ranie to talv up the entrifugal thrust as the said carriers revolve about the machine. l larh thread arrier may also have a roller 30 at the top, aiding in resisting centrifugal thrust, and cooperating with guard ring 31 to prevent the thread carrier from being dislodged inwardly from its position.

As the main revolving frame and the roller frame are revolved in opposite dired tions about the machine. and the tl'iread or strand '1 is arried over and under the thread carrier in the usual manner, the pas sage of the thread "l between the lhrcad arrier rollers and the supporting and driving rollers is aided by the rotation of the said rollers by means of the friction wheels travcling on the ledge 23 on the main revolving frame. The relatively positive drive of said rollers caused by said friction wheel is of especial advantage Where the machine is operated upon light material which would be likely to break if the rollers were idler rollers and the tension of the thread itself were relied upon to pull the thread between the rollers.

I claim:

1. A braiding machine comprising a lined and a main revolving frame, a revolving roller frame, means to drive said Flames in opp sih? direc ons, llireadrarrier supporling and driving rollers arranged in pa s on radially disposed axes carried by said roller frame, a series of thread carriers each having a roller resting on one of said pairs of supporting and driving rollers, and friction wheels fixed to said supporting and driving rollers to turn therewith and cooperating with said main revolving frame to rotate said supporting and driving rollers and also said rollers on the thread carriers.
