HUGH HENDRY, OF NEWARK, NEW JERSEY.

SELF-ACTING SPINNlNG-MULE.

SPECIFICATION forming part of Letters Patent No. 225,984, dated March 30, 1880.

Application filed November 10, 1879.

To all whom it may concern Be it known that I, HUGH HENDRY, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Self-Acting Spinning-Hides, of which the following is a specification.

My invention relates to the means made use of for regulating the tension of the yarn in spinning-mules, whereby a more perfect winding of the yarn upon the cop is. effected; and it consists in a lever, in combination with the carriage of the spinning-mule, the underfaller, the counter-balance, and devices between the faller and lever for effecting a gradual lessening of the tension at a point in the order of winding where hitherto the yarn has been subject to snarling because of a slack windin g, or to breaking and weakening by the tension being too strong. In the former order the tension from the under-faller K remained the same throughout the en tire length of winding each stretch on the cop, and the difficulty has been, from the uniformity of this tension, in winding the yarn up close at the last end ofthe stretch, so as not to cause or allow a snarl, and at the same time preserve the full strength of the yarn. These difficulties by my improvement I now overcome.

In the drawings, Figure l is an end view of the unile-carriage, showing the relation of my improvement to the winding. Fig. 2 is a plan of the lever, weight, Ste., employed in my improvement.

A is the lever; B, the stud or journal; C, the counterbalancing-weight, and I) the stand, which is the fulcrum of the lever, bolted to the floor, where the carriage E may pass over it. The carriage moves on the tracks F', made fast to the floor, and has the wheels F, hung to the arms A', united to the carriage, but broken off in the drawings to show other parts.

To the carriage, by a bracket, B', is hung a weighted lever, G, to the outer end of which is united a strap, H, having the upper end secured to the periphery of a quadrant, I, and to this quadrant is hung the under-faller K, having the wire K', extending through a series offallers lying under the yarn M. The weighted lever G acts with uniformity on the strap H and on the faller K throughout the length of the stretch being wound, producing uniformity of tension.

The yarn is brought from the rollers L, attached to the stationary part of the machine, to the spindle N, where, when twisted, it is 1- wound upon the cop-tube or spindle l?.

O is the faller or guide, having the wire O' lying above the yarn, and is used to guide the yarn down the cop and back along the line of winding up.

' The lever A is located near the lever G, so that an arm or roller, G', having a sliding connection with the lever G, making it adjustable, will reach out, and by the roller G' will ride upon the lever A.

It will be understood that the yarn delivered from the rollers L to the spindle is spun as the carriage recedes from the rollers, and is wound upon the cop as it returns toward the rollers, the faller K and the wire K' constituting the tension on the yarn, which, as I have before said, being uniform, remains the same throughout the length of the stretch to be wound.

To regulate this tension so that winding will be perfect throughout the length of winding the stretch, the lever A, with the weight G, relieves the strain on the faller K by the arm or roller G' riding up the incline upon the lever A as the spindle moves up toward the rollers L.

As it will be seen, the lever G, hanging to the carriage at B', and by the strap H operating the faller K, is lifted as it moves toward the fulcrum D, which reduces the tension and regulates it perfectly to the portion of the stretch being wound. The approach of the roller G' to the fulcrum increases the counterbalancing eect of the weight C, corresponding to the approach of the yarn to the point of the cop, and in this wayI secure a perfect automatic tension.

In the place of the weight C a spring may be employed as a counter-balance, and the lever and the devices for a counter-balance may be differently located in the machine, in connection with the under-faller, and substantially the same effect be produced.

The stand D, in being secured to the floor,

'will be adjusted in relation to the position of roo the roller G', being;` controlled by the amount of tension required for different kinds of yarn, coarser or ner.

By changing the position of the Weight and lever they maybe applied to allow the tension to come gradually onto the yarn at the beginning of Winding each stretch. Therefore What I Claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, With the lever A, having the Weight C and fuloruul B, of the earriage E, under-taller K, and connecting devioes between said faller and lever, substantially as and for the purposes specified.
