To all 'whom 'it may concern: hold the loose end of the yarn from the reserve bobbin, 55

Be it known that I, WILLIAM G. RAGsDALE, a citizen the outer end of the spindle is notched and slotted for f the United States of America, residing in Jamesthis purpose. town, in the county of Guilford and State of North In the accompanying draWings,`Figure l shows a l side elevation of my improved bobbin holder with a bobbin in position to feed to the spooling mechanism, and a reserve bobbin ready to take the place of the other bobbin when the latter has fed all its yarn. Fig.

2 is a view in elevation of the outer end of the holder with full bobbins therein. Fig. 3 is a perspective view oi the same. Fig. 4 is a perspective view showing 65 the manner in which an empty bobbin is discharged and a iull bobbin is made to take its place. Fig. 5 isa detail view on an enlarged scale and in section showing the manner in which the spindle is connected with its v supporting frame. Fig. 6 is a perspective view of one 70 n of the blocks carried by the spindle to which the side guards are connected. Figs. 7, 8 and 9 show parts of the devices for connecting the spindle to its supporting frame.

The supporting frame, A, is provided with a clamping device, A, by means of which it may be secured to the bobbin-holder-supporting-bar, B, of a spooling ma chine in the usual way. The fixed rest, C, for the My invention relates to that class oi bobbin holders Which are employed in yarn spooling machines to support bobbins during the unwinding oi yarn therefrom in which provision is made for holding the bobbins on its rest. When the yarn is all unwound from the to quickly move the empty bobbin sidewise from lts frame, A. This xed rest is in general of ordinary construction except that it is prolonged laterally on one side, c/, for a purpose hereinafter described. Thesupthe guards.

The primary object of my invention is to provide means whereby the act of discharging a spent bobbin from its rest will bring into place a reserve or full bobbin. In this way considerable time is saved in keeping the bobbin holders supplied and the output of the machine is correspondingly increased. slot, d@ to receive the loose end of the yarn from the In carrying out my invention, I provide a single reserve bobbin. The spindle also projects beyond the fixed rest or trough and two sets of side guards which rear side of the frame, A, and while it is adapted to are loosely connected to opposite sides of a spindle turn about its own axis in this frame, it is provided with spindle, D, which projects out beyond the outer end of 85 While one bobbin is held in its rest and the yarn is to the spooling machine. For this purpose the spindle being unwound therefrom, another full bobbin, or reis preferably shouldered at,A e, and bears against a boss, serve bobbin, is held between another set of side guards f, on the iront side of the frame, A, and the reduced ciron the opposite side oi the spindle, and when the culai portion of the spindle is threaded at its outer end 95 spindle is turned to cause one set of side guards to disand receives nuts, G, between which and a sliding charge the empty. bobbin from its rest, the other set block, H, is interposed a coiled spring, I. The block,

of guards carry the reserve bobbin onto the fixed rest H, is adapted to bear against the outer end of a boss, j,

or support and the loose end of the yarn may be imon the back side of the frame, A, and is normallypressed mediately attached to the spooling mechanism. The into engagement therewith by the spring, I, which also reserve bobbins can be placed in position while all tends to press the shoulder, c, against the boss, f. The

the other bobbins are feeding to the spool mechanism front side of the block, H, is provided with recesses, 7L,

and when the attendant has nothing else to do. While and a pin, K, passing through the recesses and through the bobbin is feeding yarn to the spooling mechanism, the spindle prevents the block, H, from turning on the the spindle, which supports the side guards, is locked spindle but allows it to move endwise thereon. Lugs, in place, but the locking mechanism is such that it L, project rearwardly from the boss, f, on opposite can be easily loosened to permit the spindle to be sides of the spindle and are adapted to enter the returned when the attendant so desires. In order to cesses, h. When so entered the block cannot tum relatively to the frame, A, and therefore the spindle is prevented from turning. The walls of the recesses, h, are, however, so formed that the lugs, L, may be made to leave the recesses, h, when the spindle is turned to the right by the attendant. It will be observed that the walls, hf, of the recesses are straight, while the walls, h2, are curved or inclined. This construction affords cam surfaces so that when the spindle is turned by the attendant to the right the lugs will ride on the inclined surfaces and cause the sliding block to move backwards until the lugs are disengaged, and then the spindle can turn freely through an are of 180 degrees when the block will again spring forward, the lugs will be engaged and the spindle locked. This lock acts positively tal rotation of the spindle, but it may be easily disengaged by the attendant when so desired.

I employ what is known in the art as side guards for the bobbins and which are of the usual construction and operate in the usual way except that l employ duplicate sets of guards, whereas before only one set has been used. Each set of guards comprises wire trames, M, which are pivotally connected with their supports in such manner as to have a certain freedom of movement but which movement is limited. In my bobbin-holder the side guards are pivotally connected with the centrally arranged spindle, D. For this purpose the spindle is provided with blocks, N, which are formed with recesses, n, into which the ends of the guards extend and the walls of which limit the swinging movement of the guards in such manner that, while permitting the guards to spread apart or open in order to receive or to drop a bobbin, they are not permitted to spread to too great an extent.

As shown in Figs. l, 2 and 3 a full bobbin, X, lies in its fixed rest, C, and is held in place by the guards, M, in such position as to supply yarn to the spooling mechanism. These figures of the drawings also show a reserve bobbin, X, held in similar guards immediately above the bobbin, X, on the opposite side of the spindle, D. x, indicates the yarn from the bobbin, X, leading to spooling mechanism, while x, indicates the loose end of the yarn from the bobbin, X, which is held in the outer end of the spindle in convenient position to be taken hold of by the attendant when desired. As soon as the yarn has all been drawn from the bobbin, X, the attendant by merely turning the spindle, D, to the right, may eject the empty bobbin, indicated at Y in Fig. 4, and in so doing will bring the reserve bobbin, X, into feeding position on the fixed rest, X. It will be observed that the portion, c, of the rest, C, is prolonged in such manner as to meet the reserve bobbin as it descends and guide it into feeding position on the rest. Were it not for this portion, c, the reserve bobbin would fall out of the guards, The opposite side of the rest, however, is not provided with a portion similar to c, so that when the spindle against all accideni is turned the empty bobbin will drop out into a suitable receptacle. It will be understood that the reserve bobbins may be placed in position while the other bobbins are feeding to the spooling machine and when the attendant is not otherwise engaged. ln this way much valuable time is saved and the output of the machine is correspondingly increased.

l have shown the best way now known to me of carrying out my invention, but l believe that l am the first to provide a bobbin holder with means for supporting a reserve bobbin which is brought into feeding position in the holder when an empty bobbin is ejected. I therefore do not wish to be limited to the details of construction or the particular construction of apparatus illustrated and described.
