mn eu n fled ma 1, 1908. serial are. 435,974.

of the cialyl of New. York, borough of Brook 1 l in e county of Kings and Stateof ew York have invented a new and Im proved Lubricating Attachment for Wind-- in -Machines, of which the following is a jmer of which is threaded and the latter of fu l, clear, and exact description.

This invention relates to certain im rove- I r m- ,wax, or-ot er similarma e like, as the, latter is being wound onto a spool, bobbin,-

ments in ap lying a lubricant, as, stance, para I terial, to yarn, thread, or

or spindle.

Various winding machine, as, for instance, while passing from a skein to a bobbin. The applying of the lubricant to a single thread or stran presents certain diflicu ties, in that if sufficient pressure be applied to the thread -vation of the to lubricate it to the eslred extent, the thread isoften broken, or if there is a knot or enlargement in the thread, the thread will break when said knot or enlargement comes in contact with the lubricant.

The object of my invention is to apply the lubricant tothe thread after it is wound on the bobbin or the like, the lubricant pref-' erably being in solid form and held against the sides of the several windings on the.

bobbin as the latterrotates.

Reference is who had to the accompany-f forming apart of thiss of mechanism constructed in accordance with my invention, and Fig.2 is a side eleparts shown in Fig. 1, the spindle or bobbm bein removed.

My invention is ap lcable for use in any type of winding mac e, and the lubricant may be held a inst the material while wound on a bob in, spindle, spool, or any other rotatable member; the materlal to be lubricated may be yarn, or thread of cotton, wool, or any other material.

In the accompanying drawings, I have shown a portion of'a common type of machine for winding yarn from skems to the bottle bobbin used on knitting machines.

The bobbin 10 is-mounted for rotation and difierent mechanisms have. been designed and employed for lubricating a single strand of yarn or thread while in a portion-of my 3 In connection with this winding 1 is adapted to receive .yarn thereom 'Ad ,jacent the bobbin, there is mounted a base or. platform 11, vertically movable under the action of a cam or any other suitable mech and upon platform is mounted a sm .filde and the controlling means therefor . of machine, the platform .11 carries two uprights 12 and 13, the forwhich is smooth. Mounted on the threaded upright 12 is a cone 14 having a thin bar At the lower end of the cone and rotatable in respect thereto, is a collar 17 having two arms 18 and 19. The arm 18 terminates in a sleeve encircling the upr' ht 13 and serves to preventthe rotation of t e arm 18 about ht 12, so that as the upr' ht 12, and the-arm 1-9 carries a yarn gui e 20 adjustable in respect thereto. he entire mechanism'mounted on the base 11 is moved up and down, so that the ide 20 is moved ongitudinally of the b0 bin.

When the yarn hasiaccumulated onthe lower end of the bobbin to such an extent that. it contacts the conei the latter is rotated-to travel u the upright 12' and rais'e'th'e. 'de. old-and t e details thereof constituten invention.

. mechanism, I employ an attachment for applging a lubricant, preferably arafiin, to t e yarn as it is wound upon e bobbin. In

' of this mechanism is the specific form shown, this attachment" comprises an arm 21 mounted to swing on the upright 13 and disposed above the arm '18, so as. to be moved upward when the cone 14 is rotated to raise the arms 18 and 19.

At the outer end of the arm 21 is a suitable down and the entire outer surface each layer of yarn on the bobbin is thoroughly and eflectively coated with the lubricant.

. The lubricant may be held against the bobbin with any desired amount of pressure, and it will not tend to break the yarn or be interfered with by the passage of a knot, en-Z largement or other obstruction in the yarn. By holding the lubricant against the yarn on'the bobbin, the yarn passes it several times before being covered by" a second layer of yarn. The lubricant'serves to hold the yarn in place on the bobbin, and serves to a certain extent to guide or direct it. When a single strand of yarn is drawn ast the lubricant, a difference in the s ee I of winding at the be ning and the en of the bobbin, makes a lubrication, but the lubrication is uniform when the lubricant is held against the bobbin as in my construction.v

Various changes may be made in the construction and details of the lubricating attachment, and it may beapplied to various diflerent ty es of .machines.

In the 0 owing-claims, the term yarn is used to cover any and all forms of threads or strands, irrespective of the material, and the term bobbin is used-to designate any type of rotary member upon which any type of am is to be wou'nd.

liaving thus described my invention, I

ifl'erence in the degree of new claim as new and desire to secure by Let ters Patent:

1. In a winding machine, the combination of arotatable member upon which the yarn is to be wound, and means movable longitudinally of the rotatable member for re- ,siliently holding a lubricant against the wound ya'rn on said member, said means includin a U-shaped bar of spring metal, the terminal portions of which form sprin jaws for engaging with opposite sides 0 the lubricant and a clamping bolt extending through both of said jaws at a distance from the end thereof for moving them relatively to each other.

2.- In a winding machine, the combination of'a rotatable member upon which the yarn is to be wound, a guide movable longitudinally of said member for directing the yarnthereto, and means movable lon itudinall of the rotatable member and wit said gui e for holding a lubricant against said yarn after it is wound on said member, said holding means includin two spring-pressed jaws having inwardly-directed teeth and a clamping bolt for drawing said jaws together.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

'SELIG BROADWIN.
