ALONZO E. RHOADES, OF HOPEDALE, MASSACHUSETTS, ASSIGNOR TO DRAPEB CORPORATION, OF HOPEDALE, MASSACHUSETTS, A CORPORATION OF MAINE.

To all whom it may concern Be it known that I, ALoNz'o E. RHoADEs, a citizen of the United States, and resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Yarn Supports and Guides for Winding-Machines, of Which the following description, in connection with theaccompanying drawing, characters on the drawing representing like parts. a

This invention relates to improvements in yarn supports and guides for Winding machines in which the yarn supplying means areso wound as to require the running strand to be drawn ofl' substantially in the axis of the yarn supplying means asin the case of filling wound bobbins.

a In order to unwind such yarnsupplying means it is desirable to provide guiding means positioned closely tothe nose otand substantially in line With the axis of the bobbins. Inusual yarn yvinding machines such as spooling'machines the yarn supplying means are supported upon relatively short studs which enable the yarn supplying means to be dofi'ed and replaced beneath the guiding means.

As bobbins vary in size, shape andlength and have bores of dilierent diameters it is in many 1nstances imposslble to retaln them upon the short studsof the usual spoolers.

If longer spindles are employed, Which will properly support bobbins of dilferentsizes and having different bores the guiding means for the running strandhasto be located so far from the nose of the bobbin, to provide for dotting and replacement, that therunning strand is not properly drawn Off of the bobbin. a

The principal object of the p-resentinvention is to provide a combined support for the yarn supporting means or bobbinand a guiding means for the running strand in which a relatively long spindle adapted to support any kind of bobbin or yarn supplying means may be employed and a guiding means positioned closely adjacent the nose of the bobbin.

This is accomplished in the present invention by providing a bracket having a is a specification, like Specification of Letters ratent. t t June 2 k915i Application fi1ed October 5,1918. Serial 1%. 256,946.

relatively long spindle and securing to the uppjer end of the bracket a guidepivhich whenin normal position is in the axial line of thespmdlabut which may be removed, preferably by being swung aside, to permit the dofiing and replacementvotthe bobbins or otheryarn supplying means.

A furtherpbject of the invention is to p-rovidea guiding means of the character specified which when syvung aside to permit the placing on or the taking ofi of the bobblIlS Wlll automatically return to its normal gulding position when released by the operator. a y i y A further object of the invention is to provide a bobbinguide of the character descrlbedwhich willvbe returned to its guidlng pos tlon by the force of gravity thereby avoiding the necessity of springs.

ing bracket and yarn guide embodying my invention, a

\Fig. 3 is an enlarged plan view of the same showing in full lines the guide in normal position and in dotted lines the guide swung aside to permit dotting of the bobbin, and,

t Fig. 4 is a detail end view of the guide forthe yarn showing the manner in which it is pivotallysupported upon the bracket.

The spooler which is illustratedin the accompanying drawingsis of a usual type comprising a frame 1 having the usual top rail 2 upon whichis mounted a series of spindles 3 which are adapted to be rotated by, whirls 4, said spindles being provided with means for supportingspools or other yarn receivers 5. The yarn receivers 5 are rotated in the usual manner by belts passingaround a driving drum 6 and the whirls 4:. The yarn is caused to traverse the spools is carried upon rocker arms 9 extending upwardly from shaft 10 which are oscillated through yokes 11 in the customary manner; i

The construction thus described is of a usual character and my invention contemplates an improved support for the bobbins and guide for directing the running strand as it leaves the bobbin to be drawn through the guide upon the traverse rod to the spool.

preferred bobbin support which is illustrated herein comprises a bracket 12 having means, such as a notch 13. and 0p. posing set screw 14, for securing the same to a rod 15 extending longitudinally of the spooler frame andsupported therefrom bv brackets l6. v

The bracket 12 has at itslowerend a lateral extension 17 which'supports a. spindle 18 which may be provided with conical sections 19, 20 and 21 of different diameters.

The bracket is also provided with an arm 22 extending upwardly to a distance some what beyond the end of the spindle 1 8. The upper end of the arm 22 has a laterally extending boss 23 which is bored longitudinally to receive the pivotal stud 24 of the yarn guiding means. The yarn guidingmeans comprises a member 25 which preferably extends upwardly and laterally from the bracket arm 22 and has a bifurcated extension'26 which forms a .-shaped guide for the running strand, the the bifurcation preferably being in alinement with'the axis. of the spindle 18 when the guide is in normal position as illustrated in full lines in Fig. 3. The upper end of the bracket arm 22, or the boss 23, is provided with an upward extension 27 extending partially around the pivotal stud 2-1, the face of said extension presenting a shoulder 28 adapted to engage a comple-- mentary shoulder upon a downward extension 29 on the guiding member 25. The shoulder 28 is so positioned that when the downward extension 29 of the guiding member 25 engages it,the apex of the thread guiding recess in thebifurcated'extension 26 will be positioned directly over the axis of the spindle. It will thus be obvious that when in normal position the guide may be located in such proximity to the bobbin as to direct the yarn running from the bobbin substantially in the axial line of the bobbin and that it may be swung aside to enable the bobbin to be placed upon or removed from the spindle.

When placed upon the spooling frame, the bracket desirably is secured in a position inclined to the horizontal approximately 45 degrees and the connection between the bracket and guiding means is such that when in this position the guiding means will return by gravity to its norapex of mal position in line with the axis of the bobbin. Thus the necessity for springs or locking means for securing the guide in place is avoided and a simple construction provided which will not be likely to become broken.

When the empty bobbins are to be replaced by fresh ones, it is merely necessary to swing aside the pivotally mounted guide to enable the empty bobbin to be pulled directly off of the spindle and a new bobbin to be placed upon the spindle. When the guide is released it will instantly return'to normal position by gravity whereupon the yarn may be carried directly up to the traverse mechanism and led to the spool without the necessity of threading its endthrough an eye, so that a considerable amount of the operators time is saved in replenishment.

It is to be understood that the specific embodiment of the invention disclosed herein is of an illustrative character and that various modifications in form and construction may be made within themeaning and scope of the following claims.

Having thus described my invention, what I claim as new aad desire to secure by Letters Patent is:

1. In a spooler, a support for bobbins having a filling wind comprising a stand having a spindle for the bobbin and a guide pivotally mounted on said stand normally positioned to direct the running strand substantially axially of said bobbin but capable of being swung from said position to permit the dofling of the bobbin, said guide tending under the action of gravity to return to normal position.

In a spooler, a bobbin support comprising a bracket having a spindle positioned at an inclination to the horizontal, an arm extending in parallelism with said spindle, a guide pivotally mounted upon the upper end of said arm, means for limiting the pivotal movement of the guide under the action of gravity to hold the guide in position to direct the strand running from the bobbin substantially axially of the bobbin but capable of being swung aside to permit the doffing of the bobbin.

3. In a spooler, a bobbin support comprising a bracket having a spindle positioned at an inclination to the horizontal, an arm extending in parallelism with said spindle, a guide overhanging the end of the spindle pivotally mouinted upon the upper end of said arm and said guide and said arm having cooperating shoulders to limit the movement of said guide, so positioned that the guide will normally be held by gravity in position to direct said strand axially of said bobbin but enabling the guide to be swung aside to permit the doifing of the bobbin.

4. A bobbin stand for spoolers comprising of the spindle and acting to direct the runa bracket having means for adjustably atning strand of yarn substantially axially taching the same to the side rail of the of said bobbin and means to limit the eX- 10 spooler at any desired inclination, a spihtent of swinging movement of said guide. 5 dle for the bobbin an arm extending in In testimony whereof, I have signed my parallelism with sand spindle, a guide pivname to this specification. otally mounted thereon overhanging the end ALONZO E.
