JOHN GOOD, or BROOKLYN, NEW YORK.

MEANS FOR CONTROLLING THE UNWINDING 0F THREAD, TWINE, AND CORD FROM BOBBINS AND SPOOLS.

SPECIFICATION forming part of Letters Patent No. 352,312, dated November 9, 1886.

Application filed December 5, 1885. Serial No. 184,798. 1 (No model.)

To-aZZ whom it may concern:

Be it known that 1, JOHN GOOD, a citizen of the United States, residing in the city of Brooklyn, in the county of Kings and State of New York, haveinvented a new and useful Improvement in Means for Controlling the Unwinding of Thread, Twine, and Cord from Bobbins and Spools, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to what may be termed gravity traversing guides, used in connecmonly applied, and especially to adapt them. to balling-machines for balling heavy twine and cord; and the invention consists in the novel construction of parts, hereinafter described and claimed, whereby the desired result is obtained.

,The accompanying drawings represent my invention applied to the supply-bobbin of a machine.

Figure 1 represents an elevation, partly in section, of a bobbin and its support having my invention applied. Fig. 2 is a plan of thesame. Fig. 3 is a vertical sectional view of the gravity traversing guide audits appurtenances, taken at right angles to Fig. 1.

Similar letters of reference indicate corresponding parts in the severalfigu-res.

A. in the drawings designates part of the top framingof a balling-machine,which forms the base ofthe bobbin-support, the other parts of said support consisting of fixed upright posts 0 0'0 and a cap, B.

D is the bobbin fitted loosely to an upright spindle, E, which passes through the cap B of thesupport and entersaloosebushing,f, which is fitted into abearing in the base A, and which is integrally formed with the friction-disk F.

The foot of the bobbin is attached to this friction-disk in the usual way of attaching bob- .bins to such disks, or in any suitable manner, so that the said disk is compelled to turn with rial, to equalize the friction which is produced between the bobbin and its supporting-base A by the weight above mentioned and the rotation of the-bobbin.

G is a guide, consisting of a sheave pivoted in a fixed position to the cap B of the bobbinsupport.

H h designate the principal parts of the gravity traversing guide, consisting of a hanger, H, and a broad sheave, h, pivoted thereto, the said hanger being fitted to slide freely on the upright posts 0 O of the bobbin-support parallel with the axis of the bobbin, the said posts 0 0 being set far enough apart to receive between them the broad sheave h, the sheaveholder h, which will presently be described, and the part of the hanger H below them, and thereby keeping the planes of rotation of the said sheave in proper relation with the bobbin and the unwinding twine or cord. The

. combined weight of the hanger H and its sheave may be properly proportioned relatively to the tension or drag on the yarn produced by the friction between the bobbin and its base; but

as this proportion may require to be adjusted or varied to suit varying circumstances, I attach to the hanger by screws or otherwise a weight, a,which may be changed for a heavier or lighter one, and I provide on the bottomof the hanger H an eye, 1), into which may be hooked an additional weight, as may be necessary.

In order to prevent any jerking on the twine.

by the loaded traversing guide hung thereon between the bobbin and the guide G, Ido not pivot the sheave it directly to the hanger H, which constitutes or carries the load of the traversing guide, but I pivot it into a forked holder, h, which is fitted to slide freely and vertically within the hanger, and the lower part'of which is connected with the hanger by a spring, 1L2, so that the hanger and any Weight attached to it is suspended from the sheave and through it from the twine, through the medium of the spring, which, to a great degree, counteracts the effects of the jerking which might otherwise be produced by the changes of direction of the guide and its load. In the drawings the twine is represented as passing from the'guide Grv to and under a stationary guide-sheave, 1', and thence to a guide sheave, J, in the head K of the flier of the balling-machine. These guide-sheaves constitute no part of the present invention, but are elements of combination forming part of certain improvements in balling machines which are the subject of my application No. 187,691, filed January 5, 1886, forUnited States Letters Patent, and they are only represented here to give such illustration as may be required in this specification of the practical application of this invention. v

In the operation-of my invention the twine tpasses from'the bobbin D to and under the sheave h of the traversing guide, thence upward over the sheave G to any take-up apparatus or machine in connection with which the invention is used. As the twine is unwound from the bobbin, the gravity-guide traverses the whole length of the bobbin, causing the draft of the twine to be at all times in planes parallel with the planes of rotation of the bobbin, a'ndthe movement of the said guide, owing to itsconstruction and the combination of its sheaves and hanger with each other and the fixed guide-posts O 0, is free from jerks and twists and perfectly steady and uniform.

What I claim as my invention, and desire to secure by Letters Patent, is-

The gravity traversing guide consisting of the combination of the hanger H, the movable sheave-holder fitted to said hanger, the sheave h, fitted to said holder, and the spring h, connectingthe said holder and hanger, all substantially as and for the purpose herein set forth.

1 JOHN GOOD. \Vitnesses:
