BOBBlN-HOLDER.

SPECIFICATION forming part of Letters Patent No. 762,088, dated une '7, 1904. Application filed January 25, 1904. Serial No. 190,534. (No model.)

To (LZZ whom it may concern.-

Be it known that we, J OHN RoNEY and JOHN (J. RAE, citizens of the United States, residing at oonsocket, in the county of Providence and State of Rhode Island, have inventednew and useful Improvements in Bobbin-Holders, of which the following is a specification. I

Our invention pertainsto bobbin-holders; and it has for its object to provide a simple and sturdy bobbin-holder adapted to be frictionally secured on a spindle and one which may be depended upon to prevent casual flying up of a bobbin and the waste frequently occasioned thereby.

The invention will be fully understood from w the following description and claims when taken in connection with the accompanying drawings, forming part of this specification, in which Figure 1 is a View, partly in section and partly in elevation, illustrating our novel holder as frictionally secured on the tapered portion of a spindle and holding a bobbin. Fig. 2 is an enlarged view, partly in side elevation and partly in diametrical section, of the bobbin-holder removed, the section being taken on the line 2 2 of Fig. 3. Fig. 3 is a plan view of the bobbin-holder.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which* A is a spindle which has a lower tapered portion a and is otherwise of the ordinary construction.

B is a bobbin arranged on the spindle in the usual manner and provided at the side of its lower portion with means for the engagement of the jaws of a bobbin-holder, which means in the present instance is a circumferential groove 6.

C is the bobbin-holder constituting the present and preferred embodiment of our invention. The said holder comprises a bushing or annulus 0, preferably of brass, having an exterior shoulder (Z, an annular cup 0, preferably of steel, surrounding the upper portion and bearing on the shoulder (Z of the bushing and brazed or otherwise fixed with respect thereto, jaws f for engaging and holding a bobbin, and a spring 9, surrounding the upper portions of the jaws and tending to press the same inwardly against a bobbin. As clearly shown in Fig. 2, the cup eis provided at its base with an outwardly-extending integral flange it. This flange is provided with three (more or less) equidistant verticallydisposed slots 9:, and in the said slots are arranged reduced portions at the lower ends of the jaws f, which reduced portions are bent inwardly below the cup, whereby it will be seen that the jaws are connected to the cup in a hinged manner, and hence are free to move inwardly and outwardly at the outer side of the side wall of thecup.

In using our novel holder the same is placed and pressed down hard on the tapered portion of the spindle, so as to frictionally secure the bushing c to said tapered portion, after which the bobbin is placed on the spindle and its lower end is seated in the cup 6 between the jaws f and is held by the latter after the manner shown in Fig. 1. When the bobbin is thus held, it will be observed that casual upward movement of the same on the spindle is precluded, and hence there is no liability of yarn piling up on a part of the bobbin that is already filled and rendering the bobbin too large to enter a shuttle.

The cup 0, as will be readily observed by reference to Fig. 1, serves as a seat for the bobbin and assists materially in holding the same in place. Said cup also lends strength to the bottom of theholder and prolongs the usefulness of the same; and it further serves.

as a stop to prevent undue inward movement of the upper portions of the jaws f and at the same time reinforce said jaws when the same are engaged in holding a bobbin.

While we prefer to provide the cup with a bushing, as c, we desire it understood that the cup may be adapted to directly engage a spindle without involving a departure from the scope of our invention. v

The bobbin-holder herein' shown and described constitutes the preferred embodiment of our invention, and we haveentercd into a detailed description of the construction and relative arrangement of the several parts in order to impart a definite understanding of the invention. WVe desire it understood,

however, that in practice such changes or modifications may be made as fairly fall within the scope of our claims. 1

Having described our invention, what we claim, and desire to secure by Letters Patent.

1. As an article of manufacture, a bobbinholder comprising a cup shaped to seat the lower end of a bobbin, radially-movable bobbin-clamping jaws hinged to the cup and disposed at the outer side of the side wall of the same, whereby undue inward movement of the upper portions of said jaws is prevented, and means for pressing the upper portions of the jaws inwardly.

2. As an article of manufacture, a bobbinholder comprising a cup shaped to seat the lower end of a bobbin, and having an outwardly-extending base-flange, radially-movable bobbin-clamping jaws disposed at the outer side of the side wall of the cup and hinged at their lower ends to the base-flange thereof, and means for pressing the upper portions of the said jaws inwardly.

3. A bobbin-holder comprising a cup shaped to seat the lower end of a bobbin, and having an outwardly-extending base-flange provided with vertiCally-disposed apertures, radiallymovable bobbin-clamping jaws disposed at the outer side of the side wall of the cup, whereby said wall limits und ue inward movement of the upper portions of the aws, and reinforces the same; said aws having reduced lower ends loosely arranged in the apertures of the base' flange on the cup, and bent below said flange, and means for pressing the jaws inwardly.

4. A bobbin-holder comprising a bushing having an exterior shoulder, an annular cup surrounding the upper portion and bearing on the shoulder of the bushing and fixed thereto; said cup being shaped to seat the lower end of a bobbin, and being provided with an outwardly-extending base-flange provided with vertically-disposed apertures, radially-movable bobbin-elamping jaws normally resting against the outer side of the side wall of the cup, and having reduced lower ends loosely arranged in the apertures of the base flange on the cup, and bent below said flange, and a spring surrounding the upper portions of the jaws.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
