ALLAN E. BURTT, OF HOPEDALE, MASSACHUSETTS, ASSIGNOR TO DRAPER COMPANY, OF .HOPEDALE, MASSACHUSETTS, A CORPORATION OF MAINE.

FILLING-TENSION AND CONTROLLING MEANS FOR LOOIVIS- No.s2e,922.

Specification of Iietters Patent.

Patented m 21, 1906.

Application filed November 13.1905. Serial No. 287,033.

Be it known that I, ALLAN E. BURTT, a citizen of the United States, and a resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Filling- Tension and Controlling Means for Looms, of which the following description, in connection with the accomp any-' ing drawings, is a specification, like letters andfigures on the drawings representing like parts.

This invention has for its object the production-of novel means for controlling and imparting tension to the filling as it is drawn off from the filling-carrier or bobbin in the running shuttle of a loo m, said controlling,

and tension-producing means in m present invention being mounted on the filling-carrier. By means of such invention the filling is subjected to acertain amount of tension as it travels around the tip of the carrier, and at the same time it is guided'and its ballooning or whipping around the filling carrier is greatly restricted. A very even oruniform delivery of the filling is thus effected.

The various novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a top plan view of the delivery end of a loom-shuttle and the adj acent or tip portion of a filling-carrier with one embodiment of my invention applied thereto. Fig.

herein I have shown only the portion of the.

barrel 1 of the filling-carrier at or near the tip or delivery end thereof, it having the usual longitudinal bore 2,, Fig. 2. At the ti end the bore is reamed out or counterbore as at 3, to receive tightl the tubular shank 4 of a plug 5, the shank being long enough to leave an annular clearance or recess between parallel to the longitudinal axis of the fillingcarrier.

The filling t is threaded through the eye, as shown in Fig. 1, and passes thence to the delivery-eye of the shuttle S, Fig. 1. As the filling is drawnofi through the eye it travels in a spiral path around the tip end of the carrier and in so doing, imparts rotation to the ring, so that the frictional resistance of the latter exerts a drag or tension 11 on the filling sufficient to maintain it proper y taut during the weaving operation. Thus the filling-tension is provided by means mounted directly on the filling-carrier, and such means not only provides tension, but it also guides the filling as it is delivered and limits or restricts the usual whipping action of the filling as it draws oil to be delivered. This is of very material advantage, as the filling is not so liable to catch upon adjacent portions of the shuttle, and when the filling-carrier is adaptthe plug and the tip of the carrier. In the ed for use in shuttles having an automa'tically self-threading device, as T, Fig. 1, the restriction of the-filling from ballooning or undue whipping prevents any throwing for- 4 ward of a loop of the filling into the threading device. As the filling is delivered from the eye 7, which travels in a constant circular path close to the tip of the fillingcarrier,

the conical path of thefilling between the controlling means and the passage in the shuttle leading to the delivery-eye is very materially decreased in dimensions and is maintained substantially constant at all times.

f Having fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1. A filling-carrier for loom-shuttles, havingan annular clearance or recess near its carrier, said ring having an eye through 10 tip, and an annular fillin -guide rotatably' which the filhngis drawn. mounted in said recess, sai guide havin an In testimony whereof I have signed my eye formed therein'through which the ing name to this specification in the presence of 5 is drawn ofi. two subscribing witnesses.
