TRAVERSE-RING.

SPECIFICATION forming part of Letters Patent No. 497,076, dated May 9, 1893.

Application filed February 24, 1892. Serial No. 422,686. (No model.)

To all whom it may concern: being surrounded by an annular projection 50 Be it known that I, CHARLES W. RUGG, of a and the eye 0,, being of sufficient size to Boston, county of Suffolk, State of Massachureceive the said annular projection a so that setts, have invented an Improvement in Travwhen the strip is bent into circular shape, the 5 erse-Rings, of which the following description, ends thereof, may be turned outwardly or in connection with the accompanying drawdownwardly, and brought together as shown I; 5 ings, is a specification,like letters and figures in Figs. 1 and 10, with the annular projection on the drawings representing like parts. a passing through the eye a. The annular This invention has for its object to conprojection a is made longer than the thick- IO struct a traverse ring which may be cheaply ness of the strip, or that end of it containing manufactured, is serviceable and sightly. the eye a, so that it projects through said eye 6 The invention consists of a traverse ring sufficiently to enable it to be upset or turned composed of a circular band reduced in width over upon the opposite side of the end of the at suitable points to present as many shoulstrip. This annular projection thereby serves I 5 dered connecting bars, which serve as bearas a means for securing the ends of the strip ings for split friction rolls applied to them in together, and also gives to the eye a smooth 6: the manner and for the purpose hereinafter finished interior. The strip a, is cut away at particularly set forth and claimed. each side as at 2, 3, and 4:, 5, to thereby form Figure 1, shows in front elevation a trava short narrow connecting bar 6, and shoul- 2o erse ringembodying this invention; Fig. 2, a ders 7,7; or said strip may be otherwise formed plan view of the flat strip which is bent into to provide bearings for the friction rolls to be circular shape to form the ring; Fig. 3, an endescribed. As the strip a is quite thin I have larged cross sectional view of the strip shown secured to it by solder or otherwise a reinin Fig. 2, taken on the dotted line 00-03; Fig. forcing bar 8, of a width equal to the width 2 5 4, an enlarged cross sectional View of the strip of the connecting bar 6, and of suitable thickafter its side edges have been upturned; Fig. ness to form in conjunction with said con- 5, an enlarged detail of one of the split or slitnecting bar a quadrangular bearing.

The bushing is made of suitable length to closed. Fig. 9 is a cross-section at one side fit snugly upon the quadrangular bearing 6, 8 of one of the friction rolls, showing a strip 8, between the shoulders 7, 7. having the reinforcing bar and the bushing The friction rolls 0, are provided with cirand roll applied; and Fig. 10, an enlarged seccular central holes of suitable size to turn 40 tional detail of the eye. Fig. 11 is a plan freely on the bushing b, and said rolls are View similar in scale to Fig. 2, of a modificaslitted radially like the bushings, that they tion, and Fig. 12, is a sectional elevation simimay beopened at such slit, as shown in Fig. lar in scale to Fig. 9, these last twofigures (11 5, to receive the bushings, after which they and 12) showing the split friction roll applied will be closed as shown in Fig. 6. 5 without a bushing. When the strip a, is made of thin material,

The ring shown in Fig. 1, is composed of a the side edges thereof will be overturned as fiat strip a, see Fig. 2, of suitable length and shown in Figs. 1 and 4:, or otherwise, to stiffen width, bent into circular shape. The strip a, it, and likewise improve its appearance. If has at each end an eye as a, a the eye a the strip a should be made of quite thick material, the said side edges may or may not be overturned, and furthermore in such event the connecting bar 6, may be large enough to thereby obviate the necessity of employing a reinforcing strip or bar 8.

The strip or band a may and preferably will be made of thin sheet iron or some other cheap material, and then a layer or coating of brass as a, afterward applied, thereby presenting a core of a cheap yet strong, durable material, covered or coated with a thin finishing material.

I do not desire to limit my invention to the employment of split bushings to furnish the cylindrical bearings for the friction rolls, as it is obvious that said bearings may be made cylindrical in different ways.

I claim 1. In a traverse ring, a circular band, reduced in Width at suitable points to present one or more connecting bars 6, and shoulders 7, 7, and split friction rolls having central holes through them to receive and be thereby supported on said connecting bars 6, between the shoulders, substantially as described.

2. In a traverse ring, a circular band, reduced in Width at suitable points to present one or more connecting bars 6, a reinforcing strip 8, for said connecting bars 6, and split friction rolls having central holes through them to receive and be thereby supported on the reinforced bearings thus provided, substantially as described.

3. In a traverse ring, a circular band reduced in Width at suitable points to present bearings 6, integral with the band, split bushings placed on said bearings 6, and split frietion rolls on said bushings, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES \V. RUGG.
