JOHN JAMES HEYWOOD, OF FALL RIVER, MASSACHUSETTS.

BAND FOR DRIVING SPINDLES.

SPECIFICATION forming part of Letters Patent No. 367,041, dated July 26, 1887.

Application filed February 16, 1587. Serial No. 217,787.

To aZZ whom it may concern:

Be itknown that I, J OI-IN JAMES HEYwooD, of Fall River, county of Bristol, and State of Massachusetts, have invented a new and useful Improvement in Bands for Driving Spin dles,&c. and I do hereby declare the following specification, taken in connection with the accompanying drawings,forming a part of the same, to be a description thereof.

This invention relates to bands for driving spindles, &c.; and the improvement consists in providing the band with means whereby the ends of the band may be conveniently and quickly pulled through the body-of the band, so that the strain upon the band will cause its ends to be held by the gripping force of that part of the body of the band which surrounds the ends,as hereinafter described and claimed.

It also consists in the improved method of fastening the ends to each other, hereinafter described.

The object of the invention is to enable the ends of the band to be conveniently and securely fastened to each other,and so that there will be no salient projections where the ends arejoined to interfere with the smooth running of the band, as there would be were the ends tied together in the ordinary manner.

In the accompanying drawings, Figure 1 shows a braided band provided near its ends with wire loops passed longitudinally through the body of the band. Fig. 2 represents a braided band which has a loop of wire near one end, and at the other end has a loop formed by passing the end of the band itself back through its body. Fig. 3 shows one end of a twisted band supplied with a wire loop in accordance with theinvention. Fig. 4 represents one of the wire loops. Fig. 5 represents both ends of the band shownin Fig. 1 pulled through its body. Fig. 6 represents a portion of a band after the ends arejoined ready for use. Fig. 7 represents the ends of the band shown in Fig. 2 pulled through its body. Fig. 8 shows a part of said band after its ends are joined ready for use.

A is the band, which may be braided or twisted, as are bands in common use.

B B are the loops orhooks, which may be of metal, cord, or other suitable material. The loops shown in Fig.1 are of wire,and are passed N'o model.)

longitudinally through the body of the band near its ends a a for the distance of aninch or more, the length of the band between the points a a where the loops emerge being such that when its ends are properly joined the band shall be just the desired length. In the condition shown in Fig. 1 the bands are designed to be sold to the trade and supplied to mills.

lVhen the band is to be applied to driving spindles, it is passed around the drum of the machine and around a spindle whirl. The end a is then passed through the loop B, and by said loop is pulled longitudinally through the body of the band, and the end a is passed through the loop B, and by it is pulled longitudinally through the body of the band, as shown in Fig. 5. The ends a a are then pulled upon to bring the points a together, and are then cut off where they emerge, leaving the band with its ends joined, as in Fig. 6.

Instead of securing the ends of the band by pulling them through, as shown in Fig. 5, they may be returned upon themselves, be interlocked, and be pulled back through the body. The band shown in Fig. 2 is particularly arranged forfastening the ends in this manner. Near the end a the band is provided with a loop, B, as in Fig. 1; but the end a is returned upon itself, and by means of a wire loop or other'suitable device has been pulled back through the body of the band, making a loop, B. In this condition the bands may be supplied to the trade and consumers. To secure the ends of this band,it is only necessary to pass the end a through the loop B, then back through the loop B,and by said loop pull the end through the body of the band,as shown in Fig. 7, and then finallyto pull upon both the ends a a to bring the points a together. The ends are then cut off where they emerge, leaving the band with its ends joined, as shown in Fig. 8.

I prefer to make the wire loops B B of springstock, so that when they are in place in the band their spring force,whieh tends to spread their ends and to make the loop assume the shape shown in dotted lines at Fig. 4.,willn1aterially assist in retaining the loops in the band against accidental detachment.

By fastening the ends of the band as, hereinbefore described, they will be prevented from any slipping by the gripping force of that part of the body of the band which surrounds the ends when the band is under strain or tension.

The distance longitudinally of the band between the points a a being regulated to produce the desired length of band when the ends have been properly joined, such junction can be effected by unskilled labor Without any danger of the band being too long or too short when applied.

What I claim, and desire to secure by Letters Patent, is- I JOHN JAMES 'HEYVOOD. v
