SILK AND YARN THREAD TENSION'ING AnnwAxI'NG-nEvIcEQ Application" filed April 8,

filed June 1924, by a requirem'entfor division.

All similar devices with which I am familiar, provide for waxing the thread or yarn at the time it is woundupon spools, which spools are used on the knitting machines. My device however permits. winding of the thread or yarn'upon the spools inan unwaxed condition and provides for waxing upon the knitting machine, the benefits fromthis being numerous. Less wax is necessary by theuse of the invention,'tlie knitting ma chineneed not be stopped from time to time on account; of the thread or yarn being wound upon the spools: in a 'dry' condition, such condition preventing the yarn or thread from'sticking upon the spools, which stick-' ing now causes jerking of certain springs of the machine and resultsin automatic stopping of such machine,'just as if the thread or yarn had become broken. Y

The mjachinei'when provided with my ole-- vice; will be kept clean of waxdirt, which is' particularly advantageous. in regard to "the aforesaid springs; as'when theyh-ecome' gummed with wax or the like; they will not properly act to automatically stop the maw causingloop holesin'the material, commonly knownas drop stitch, I

cause the tl readswill be-o' fmore uniform thickness. My invention provides for uniform; waxing'of the thread or yarn, whereas prev ously, the thread orthelike'was' not uniformly-waxed, and wherever heavily .waxed would cause a" thickness inlthe completed material, and wherever lightly waxed, would cause a thin place.v w 7 T One operator may attend to twice 11865 many machines when they are equippedwith my invention and the work will be of better v quality because said invention will eliminate frequenflbreaking of threads as they are drawn from he SPoolsI" These threads re- 7 I tain their uniform strength andtheir freedom from each other, eliminating sticking of threads together. the same when it is unwound from the spools Machines equipped with my invention need not be repeatedly" adjusted and readjusted with" regard to hooks which support the'work, which operations must follow each time the threads break. Very often, after each such 0' eration', some hooks are left loose and w en thus neglected, they will break after awhile, causing" more trouble, material non-uniform, losing time, etc.v I

It is one object-of'the invention to provide a new and improved waxing device from which all; of the advantages hereinbefore enumerated will" flow. Another object of the presentinvention is to generally'sim-pli fy the construction and so'form a waxing device" that it may'beread- My assembled and disassembled and may he I easily adjusted and-repaired. chine in case of breakage "of the thread or" .Another aim is to provide clearance be tween the wax block and an upstanding sleeve on thetable, which" sleeve is received a in an opening in the block, said clearance serving to collect any dirt, dye-stuff orthe like from the thread and'preventing it from. covering the lower surface of the block, which would prevent proper waxing of the thread. p 11.0 With the foregoing in View, the invention" resides in the novel suhj ect" matter; hereinwhich thet'able 10o 1 after desc:ibed and claimed, the description being supplemented by the accompanying drawing.

Big. 1 is detail perspective view oft-he waxing device supported upon an adjustably mounted arm; and

Fig. 2 is a vertical central sectional view through the waxing device.

in the drawings above briefly described, the numeral 4L designates a beam supported in any desired manner.- Upon one end of this beam, I have shown an angularly adjustablesupport- 5 for a vertically swinging carrying arm 6 of the waxlng device. By

reason of the vertical swinging of this arm,

desired tcnsioning of the thread being waxed, 1s effected. sired number'of the supports 5, arms 6 and avaxing devices and if desired, two or more of said supports 5 may be mounted upon each beam 4t. Thus, either one or a battery of many of the tenslonmg devices may be arranged on one beam 4, whileseveral beams formed with a central opening 9 through which the post or spindle 7 passes, a nut 7 being threaded upon said post or spindle in contact with the bottom of-the cup, so as to not only tightly secure said cup in place, but to rigidly anchor the post or spindle, and permit vertical adjustment of it.

Closing the open upper side of the cup 9 and forming a table to support awax cake N, is a disc-like'plate or cap 10 having a depending, flared skirt or flange 11, the latter being spaced outwardly from the annular exposed edge of the cup By the provision of this cup, the table closing its open upper side, and the flange 11, no lint, threads, dirt or the like can reach the lower portion of the post or spindle 7 to interfere with proper action of the device, and the upper portion of said post or spindle is covered and thus protected, as will hereinafterap pear.

The table 10 is formed with a central opening 12, larger than the post or spindle 7, and the lowerend of a cylindrical tube or sleeve 13 is tightly pressed into said opening and is thus rigidly attached tothe'table 10. Pressed firmly into the lower end of tubeor sleeve 13 and crowding it tightly outward against the wall of the opening '12, is a bushing 14 whose lower end is provided with an outstanding annular flange 15 lying tightly against the lower side of the table Th re may be any deweight of the rotatable parts of the device and the wax cake W is supported anti-fric- 'tionally upon the upper end of the post or spindle 7, and the bushing l-i which surrounds said post or spindle, merely holds the table against angling with respect to the adjacent, stationary parts. Vlhen the table 10 is thus supported, there isfrom one to two-thousandths of an inch clearance between it and the cup 9, which clearance may be obtained by using the nuts 7 vertically adjust the post or spindle 7 to the required extent.

The Wax cake W, it will be observed, is of cylindrical form and is provided with an axial bore 19 to receive the sleeve or tube 13, and the lower portion of this wax cake is counterbored at 20, providing clearance between it and said tube or sleeve, so that any lint, dirt, dye-stud or the like from the thread 21 may accumulate in this clearance space instead of coating the lower side of the waxing operation.

Guiding means for the thread may well comprise an inverted L-shaped eye member 22 having thread guiding eyes 23 and 24, spaced different distances from the vertical part or shank 25 of said member. This shank passes through or into an opening 26 in the arm 6 and is held by a set screw-27 When this screw is loosened, the entire member 22 may be raised or lowered as occasion may demand, to properly guide the thread 21 on a level with the table 10, and said member 22 may be swung laterally so as to guide the thread to the desired portion of the device. This adjustability is exceptionally desir-able when a table of one size. is removed and another table substituted to carry either a larger or a smaller cakeof wax, as the case may be. c

While the operation of the device would probably be understood from the foregoing, it may be brieflyexplained as follows:

The thread is drawn between the wax cake W and the supporting table 10 and by reason of the fact that the thread engages adjacent faces of the cake and the table at points spaced from the post or spindle 7 and the bearing sleeve, rotary motion will be imparted to the block and to the table.

' The "waxing operation is facilitated by having the wax cake rotate and it will of course be understood that this cake is free to move downwardly upon the post or sleeve 13, as

and 8 to "wax cake and interfering with the proper p it wears away. The weightof the wax restng upon the thread as wellas the rotary I movement of the wax cake and table, are

v lowed. However, within the scope'of the invention as claimed, variations may be made.

I claim:

and sleeve and closing the end of the latter.

instrumental in effecting the desired waxing operation.

As excellent results are obtainable from the details disclosed, they are preferably 01- 1. A thread Waxer comprising, a substan tially vertical post, a cup surrounding the post near its lower end, a sleeve rotatable about the upper portion of. thepost and adapted for passage through an opening in a wax cake, a thread supporting. cap closing the upper end of the cup, a bearing bushing arranged centrally'of the-cap and surrounding the medial portion of the post, and an anti-friction bearing between the adjacent outer ends of the post and sleeve.

2. Athread waxer comprising, a substantially vertical post, a' cup surrounding the post near its lower end, a thread supporting table closing the upper end of the cup and extending radially beyond the edge of the latter, a depending skirt at the periphery of the table, a bushing centrally disposed in the table and surrounding the medial portion of said post, a bearing sleeve secured around a portion of said bushing and extending up wardly, beyond said post for passage through an opening in a wax block, and a bearing cap connecting the outer ends of the post 3. A thread waxer comprising'a'n upstand the post, a sleeve surrounding the post above- -sa1d table, and having a bearing resting on said post, the lower end of said sleeve being tightly pressed I into said opening, and a bushing tightly pressed into the lower end of thesleeve to crowdthe latter outwardly against the wall of said opening, the lower end of said bushing being provided with; out.- standing means lying tightly against the lowerside of the table, said bushing rotatably surrounding said post.

4-. In a threadfwax'er, an upstanding post, a thread supporting table having an upstanding bearing sleeve around and protecting the upper portion of said post, and dirt excluding means-adjacent to the. lower end of the post, said means comprising an up wardly opening cup tightly secured to and surrounding the post with its upperedge in close "proximity to the lower side of the table, and a depending annular skirt on the edge of said table, surrounding said cup.

5. In a thread waxer, a rotatable table having an upstanding cylindrical memberf at its center, and a cake of wax bored vertically I to receive said member, the lower portion of l i said wax cake being counterbored to form a dirt receivingchamberthereby keeping the waxing face of the cake clean.

In testimony'whereof I have hereunto aflixed my signature. e
