UNITED STATES LESTER J. HILL, OF LEXINGTON, NORTH CAROLINA.

THREAD STAND,

Appflication filed November To all whom it met/3} concern:

Be it known that I, Lns'rnn J. HILL, a

citizen of the United States, residing at Lexingtomin the county of Davidson and State of North Carolina, have invented certain new and useful" Improvements in a Thread Stand, of which the following is a specification.

The present invention relates to knitting machines and thelike, and has particular reference to a thread stand for supporting woundbobbins for artificial silk and, the like used in the manufacture of hosiery.

At the present time these bobbins are supported upon the ordinary thread stand or bracket to support bobbins that have been wound by a winding machine, and these ordinary stands are not adapted to support bobbins of artificial silk because these stands are adapted to support bobbins that have been'cross wound and the silk will not feed properly from the bobbins in thistype of stand. 'Even when artificial silk is cross wound on the bobbinit cannot be taken ofi satisfactorily, particularly when the silk is of inferior quality or when knots are tied in the same. A further disadvantage with the present thread stand is that when the feeding of the thread is suddenly stopped, the bobbin continues to spin sufficiently to 4 slacken the thread and loop the same downwardly against the side of the wound bobbin, with the result that as soon as the thread is started in its feeding operation the slack is taken out of the thread and the latter is subjected not only to the sudden jar incident to the starting of the bobbin but is also caught against knots or other protruding portions ofthe thread which frequently results in the breakage of the thread or the dislodgement. of the bobbin.

- The present invention has for an object the provision of a thread stand which is adapted to overcome the above and various other objectionable features which have been found by usin the common type of thread stand, and whlch will prevent-the catching of the loop or slack of the thread upon the knots or projections on the wound bobbin, particularly below the conical upper end thereof.

- Another objectof the invention is to provides. stand which may receive the usual artificial silk bobbin and willpermit the knitting machine to continue in its operations to use the threadwithout breaking vat difierent' adjustments.

the thread or imposing irregular friction on the thread.

vide a thread stand with an adjustable rover support and an adjustable spindle for receiving, the bobbin, the spindle being a djustable relatively to the rover to maintain the bobbin and the rover in axial alignment This feature of the invention accommodates bobbins of different sizes and insures the proper take off of the thread and prevents the same'from becoming entangled with the knots or other projections of the bobbin.

A further object of the invention is to" provide a two part stand with the parts relatively adjustable and arranged to support the eyelet or rover in one part and the spindle or bobbin carrier in the other part, the spindle being so mounted that itmay be Another object of the invention is to proquickly swung into upright position for re- 1 ceiving a bobbin and for the easy removal of invention will in part be described in and in part understood from the following detailed description of the present preferred embodiment, the'same being illustrated in the accompanying drawings, wherein:

7 an einpty bobbin, and also providing an ad- I stand or the istering opening and a vtion and by suitable construction but which are adjustablerclatively toeach other. These sections 10 and 11 may be of strap iron or the like having overlapping bases 12 and 13 respectively and wit a Ion itudinal slot 14 to receive therethroug a pair of machine screws 15 which are threaded in the lower base portion 13. The screws 15 form set screws and are adapted to maintain the sections 10 and 11 in true alignment at all ad'ustments. 1 The section 11 is provided with suitable openings for receiving attaching screws 16 ike for securing the thread stand to a knitting or other machine. The section 11 has a vertically extending ortion at the rear end of the base 13 and w ich is forked at its upper end to provide spaced arms 17 between which is pivotally mounted a bobbin carrier or spindle, As-shown' in Fig. 6 the bobbin carrier "comprises an elongated rod or spindle 18 the inner end of'which has a transverse opening therethrough and is fitted in a collar 19 rovided with a reg- 120 with a base flange 20 upon which the bobbin 21 is adapted to rest. The spindle 18and sleeve 19 are .cou-.

pled together by a bolt '22 which passes throu h the forked arms 17, and the bolt 22 has a indi'ng nut 23 which engages the outer side of one of the arms 17 to frictionally bind the arms a ainst the opposite sides of the sleeve or colfar 19,-the latter being flattened at its opposite sides to receive the arms. I

This bobbin holder is adapted to be swung upwardly as shown in dotted lines in Fig. 2 to to receive the bobbin and is then adapts be swung down into an inclined position as shown in Figs. 1 and 2. A set screw 24 is threaded diagonally upward through the vertical portion of the section 11 and forms an adjustable stop for engagement with the flange 20 of the bobbin holder to support the latter at the desired inclination. V

The section 10 is bent upwardly at less than a right angle as at 25 and has at its upper end a returned portion which is bent at. less than right angles to the portion 25 and which terminates in spaced relation to the outer end of the spindle 18. The upper end of the section 10 carries a rover or eyelet 26 of porcelain or the like through which the thread 27 is ada ted to pass.

From Fig. 1 it wi 1 be noted that the bobbin 21 and its carrier are adjusted by means of the stop 24-into substantially axial alignment with the rover 26 so that the thread 127 will normally tend to 100 downwardly and at the same time will be ree to swin about the bobbin 21 in the path shown y the dottedline. The bobbin 21 is shown'as having the usual knots 28 below the conical seeinclining the bobbin as shown in Fig. 1 the looped portion of the thread 27 and the section 12; provided with holder pivotally upright members arrange is maintained out of contact with the knots with the sides of the bobbin so that no undue friction or breakage of the thread can When the sections 10 and 11 are spread apart as shown Fig. 3, the bobbin holder is correspondingly adjusted by retracting the sto 24 and ermitting the spindle 18 to swing ownwar ly from the dotted line position into the full line position. Various adjustments of the bobbin holder may thus be made to correspond with various adjustments of the sections 10 and 11 ofthe thread stand. r t

It is of course understood that various chan s and modifications may be made in the etail of construction and desi of the above specifically described em diment without de arting from the s irit of this invention, t e chan es and mo lfications being restricted only y the scope of'the following claims,
