COVERED ELASTIC ENDLESS BAND.

SPECIFICATION forming part of Letters Patent No. 423,713, dated March 18, 1890.

Application filed November 19, 1887.

T0 aZZ whom it may concern.-

Be it known that 1, JOHN AsHWoRrH, of Somerville, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Covered Elastic Endless Bands, of which the following, taken in connection with the accompanying drawings, is a specification.

The object of this invention is to produce an improved eXtensibly-elastic covered endless band, designed especially for use as an armlet or a stocking-supporter, and useful generally where an ornamental and protected endless band is required.

The peculiarity which distinguishes my improved band from all others is that two or more endless elastic cores, each having an endless and seamless sleeve or envelope wound or braided upon it, are united laterally by a thread, which passes alternately entirely around each of such covered cores and is looped or formed into a stitch between such adjacent cores, the outer edges of the band thus begun being ornamented by a looped or knitted border, the threads of each border surrounding one of the covered cores and forming an ornamental looped edge thereon, while the threads forming such edges or borders are bound or-held in place by an additional bindingthread, so that they cannot twist out of position.

I do not herein claim, broadly, a covered elastic endless band, as I have obtained other patents thereon, one-No. 409,001, dated August 13, 1889, on my application filed May 11, 1881, and another, N 0. 345,660, dated July 20, 1886, on my application filed October 3, 1885.

In the drawings, Figures 1 to 4 represent sections of the band expanded to bring before the covering, as hereinafter explained, although the band is formed symmetrically by the several stitches taken simultaneously, and not by completing one part in advance of the other. Fig, 5 shows the band complete, one having two cores being selected for illustration.

A represents the elastic core, an endless band of india-rubber, and B is the primary covering thereof, formed seamless and end less by winding or braiding threads thereon, so as to conceal and protect the core and Serial No. 255,661. (No model.)

leave it extensibly elastic. Two of these covered cores are shown to avoid unnecessary complication in the figures.

O is the thread or cord which unites laterally the covered strands B B, said thread passing entirely around each of said strands alternately and between the two at each such passage, forming between them a stitch or loop after every passage around either one. This serves to hold the covered strands very slightly apart, and secures a flat character to the band, instead of it being nearly or practically round by winding around both strands at once. On each edge of the bandI form a looped border, which is made of a thread or cord D or E, passed simultaneously with the thread 0 around one of the covered strands B and alternately around a part of the machine by which said thread D or E is held temporarily, as by another band, so that a succession of loop-stitches is formedby each thread D or E along one edge of the band. Vhile one thread D is forming the border along one edge the other thread E at the same time is similarly forming alike border on the other edge of the band by alternately passing around the other strand B and arounda part of the machine, forming a succession of loops, a knot or stitch being in each case formed after such thread D or E has passed around the strand B and before it forms a loop of the border, and also after forming such aloop and before passing again around the strand B. In addition to this border, the band has a bindingthread F, Figs. 4 and 5, introduced for the purpose of holding the loops of the two distinct border-threads D E from turning on the strands B B. This thread F is interwoven with the threads 0, D, and E in such a way that it engages with each loop of the border, as seen in the heavy black lines of Fig. 4, crossing at the back of the band, as in Fig. 5, alternately from one border to the other. It will be understood that the covered cores A B are stretched in a suitable extended position in the machine, and that the several subsequent operations above described go on simultaneously and form the band complete with both its borders and the binding-thread applied at the same time.
