' SHUTTLE 0R FILLEING-GARRIER FOR LOOMS.

Specification of ilettersratenta Application filed February 13, 1969. $erial No. 477,504.

To all whom 'it may concern:

Be it known that I, ORREN A. SAWYER, citizen of the United States, residing at Lowell, in the county of Middlesei: and

Commonwealth of Massachusetts, have invented a certain new and useful Improve- I ment in Shuttles or Filling-Carriers for tion.

This invention relates to shuttles or filling- Looms, of which the following is a specificacarriers for looms and its objectis to provide means for producing an increased tension on the filling just before the exhaustion ol said filling.

In carrying out this object, I arrange a frictional device in the shuttle-chamber near the pivoted end of the spindle and arrange the sameto press upon the first 'iewpturns of filling wound upon the bobbin or coptube in such a inanner as to retard the unwinding of said yarn just before these turns are completely unwound. A filling-carrier provided with such tension-producing means may be used to operate controlling means for stop-motion devices or welt-replenishing devices, as by tilting a weft-tori; in the manner shown in other applications filed by me herewith.

In the accompanying drawing, on two sheets, Figure l is a plan of the shuttle with filling-holder or bobbin and my improved tension devices represented as consisting pieces of cloth secured to the inner faces of tlieu-alls of the filling-'chainber; Fig. 2, an enlarged plan of said tension devices and adjacent parts of the shuttle-body and bobbin; Fig. 3, a plan similar to Fig. it, except that brushes are shown instead of\cloth;

Fig.4, an enlarged plan of the brushes" shown in Fig. 3'with adjacent parts of the filling-carrier and filling-holder; Fig. 5, a plan of a shuttle and bobbin similar to what is shown in Fig. 3, exceptthat the bobbin is provided with an annular groove near the base to receive the first turns of yarn wound upon-the bobbin; Fig. 6, a plan of ashuttle' injwliich a cop-tube takes the place of the bobbin and shows a bunch of filling wound upon the cop-tube before commencing to build the cop. I

The shuttle herein shown has body A; pivoted spindle B; held in operative posi tionby a spring G and adapted to carry a it will be understood that the conical stepped base at of the bobbin forms no 1part of the invention, it being necessary on y Patented- 0a. 26, 1 909.

that J a suilicient length of the filling should be wound upon the filling-holder before the. building of the cop commences and in Fig. 5 I have shown how the bunch-e or part of the filling to be acted uponby. thev tension devices hereinafter described may be in the form of a narrow ring wound ina groove (5 in order that the upper side of the groove may increase the tension of the yarn by fric tion when the yarn is being drawn there trom towardthe point or top of the bobbin,-

and in Fig. 6 I have shown a bunch e of.

fillingwound on the cop-tube 6 just below the cop E or mass'of fil ng yarn, the'Dbject of the bunch in this case being to cause a' greater friction and tension of the filling as drawn from the side of the bunch adjacent to the base of the bobbin. In all these cases, additional tension on the part of the filling first wound upon the filling-holder'may be caused. by the pressure or frictionof pieces Poi? cloth F F secured as by glue to the inner sides of the walls a a of the shuttle-chamber in contact with said first wound fillin or brushes or bristles F F may be use as shown in Fig. 4, said brushes beingsecured as by glue in holes formed in the wallsoi the shuttle-chamber.

If the groove (1 which reoeii es the bunch or first winds of tlie filling, similar to what' is shown in Figi 'o, is made. deep enou h, suliicient friction may be caused on the fill ing when the filling 1S drawn out ofsaid groove over the side of said groove farthest from the base to enable the brushes dispensed with..

I claim as my invention ,1. The combination in a filling carrienoi a shuttle-body, a filling 'holder, means for supporting said holder in said body and means for producing an increased tension on the fillin just before the exhaustion of said filling trom said holder.

2. The combination in a filling carrier, of

, a shuttle-body, a filling holder, means for supporting said holder in said body and friction creating devices arranged in said shuttle-body and adapted to prodiice an in- 10 ORREN A. SAWYER. Witnesses: v. V
