, of which the following is a specification.

My invention relates to improvements in bobbin-holders or supply-spindles for supporting bobbins delivering yarn to winding or other machines, the object of my improvement being to facilitate the placing of the bobbin on its spindle and the removing or dofling of the empty tube.

My invention is fully set forth in the following speciiication, illustrated by the accompanying drawings, in which Figure 1 is a side elevation of the bobbinholder, showing the bobbin in position for delivering the yarn Fig. 2, a front elevation of the same 5 Fig. 3, a side elevation showing the position the spindle assumes when the bobbin-tube is removed.

My invention consists, in brief, of a tilting supply-spindle, which when tilted to remove an empty tube remains in this position until a full bobbin is supplied, when It is automatically returned to its normal position.

` In the drawings, a represents the supplyspindle adapted to it the bore of the bobbintube which may be of any of the wellknown forms as generally manufactured of wood. The spindle a is supported in a tilting bracket b and held by the set-screw b2. The bracket is preferably formed with two wings c and d, bored to receive the rod e, onv

which the bracket turns, a series of brackets being generally arranged on the rod, with the latter supported in some convenient location on the machine. A collar f, adapted to enter between the wings c and d, is likewise bored to receive the rod c and is secured to the rod by any suitable means, thus serving to locate and retain the bracket b longitudinally on the rod. I prefer to use the split collar f, as shown, fastened by a binder-screw g, which clamps the collar tightly on the rod. The collar f is formed with a lug h, which engages the under side of the bracket b to limit the turning of the bracket on the rod e, thus maintaining the spindle normally in its upright position. The spindle a' is positioned beneath the tension device of the machine, which is here represented as of a usual form by dash-lines at i, and it is generally required to have the top of the spindle closely adjacent the tensions. If the supply-bobbin were located at too great a distance from the tensions, in unwinding the yarn would fly out and balloon, and it is a well-known fact that excessive ballooning of the yarn causes added resistance to delivery. To prevent this, it is advantageous to have the supply-bobbin close to the tensions, but it will be seen that in order that the bobbin may pass the tension device in placing it on or taking it off the spindle the latter must be ada ted to tilt, as shown in Fig. 3. Tilting supp y-spindles are well known in the art, and other means besides those just described might be employed for providing this feature of the present device.

y The novel feature o f the invention consists in means whereby the presence of the bobbin upon its spindle insures the retention of the latter in its normal operative position, while the removal of the bobbin insures that the spindle be retained in a different position, which facilitates said removal and. also the application of a new bobbin. I

The essential element of the device is a catch member j, preferably formed of a sheetmetal piece with a central aperture, through which the spindle passes. The member is crimped or formed with a bend at k, which portion rests on the top ofthe bracket b, presenting a rocker-bearing, the aperture in the member having play enough about the spindle to allow the member to tilt or rock. The catch or lock is formed by bending down the end of a projection of the member at Z, and this catch is adapted to engage a similar de'- tent fm, formed in a projection or lug on the collar Two lugs jz and are formed on the member by bending down narrow strips of the metal, and these lugs project downward between the wings c and d of the bracket b to prevent the memberj from turning, so that the catch l is maintained in its appropriate relation to the detent m. The weight of the bracket b and spindle c tends to maintain the spindle normally upright with the bracket resting on the lug 7L', as shown in Fig. 1, this being its position when IOO the tube or bobbin is in place; but when the spindle is tilted, as shown in Fig. 3, and the bobbin drawn off the member y' is released and the force of gravity acting on the heavier end of the member j carries the catch l into engagement with the detent m, so that the spindle is then held in its tilted position.

In practice the operation of my device is as follows: With the spindle a in the position shown in Fig. 3 the bobbin X is simply dropped onto the spindle and the head or bottom end of the tube x strikes the uplifted end n of the member y'. bobbin acting on the end n of the member y' tilts the latter and raises the catch l from the detent m, releasing the bracket and allowing it to drop into position against the lug hp rIhe bobbin is now ready to deliver to the tension device i, as shown in Fig. 1. After the yarn on the bobbin is exhausted the empty tube is drawn ofl, and this necessitates the tilting of the spindle, so that the catch Z engagesl the detent m. After the tube is removed the spindle remains in this convenient position, so that a new bobbin can be readily supplied. The instant the fresh bobbin reaches its seat on the spindle the catch lis released, and the spindle is automatically returned to its vertical position.

It will be seen that with my device the placing of the bobbin and the dofling of the empty tube are greatly facilitated. The operator need only use one hand, leaving the other free to thread the yarn in the tensions or otherwise manipulate it, while with other devices it has always been necessary to tilt the spindle with one hand and place the bobbin with the other, using both hands at the same time. It will be evident that a great saving of time and pains is accomplished by the use of my device, and its operation is most convenient.

Other means might be used for retaining the spindle in its tilted position and for releasing it when the bobbin is placed in position without departing from the spirit of this invention. Therefore I do not limit myself to the precise structure and arrangement here shown; but
