SHUTTLE FOR LOOIVIS.

SPECIFICATION forming part of Letters Patent No. 669,504, dated March 12, 1901.

Application filed. October 14,1899. Serial No. 733,626. (No model.)

. To all whom it may concern:

Be it known that I, JOHN C. BRYAN, a citizen of the United States, residing at Augusta, in the county of Richmond and State of Georgia, have invented a new and useful Shuttle for Looms, of which the following is a specification.

This invention relates to loom shuttles; and the object of the same is to provide simple and effective means for removably receiving and holdiuga carrier or bobbin and which is particularly adapted for conjoint operation with automatically-actuated feeding devices.

The invention consists in the construction and arrangement of parts, which will be more fully hereinafter described and claimed.

In the accompanying drawings, Figure l is perspective view of a shuttle embodying the features of the invention. Fig. 2 is a side elevation thereof looking toward the self-threading construction. Fig. 3 is a transverse vertical section on the line 4. 4: of Fig. 2. Fig. 4 is a longitudinal vertical section, on an enlarged scale, taken in the plane of the line 5 5 of Fig. 3.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral 1 designates a shuttle-body, which, as usual, is preferably constructed of wood, but in thisinstance has the opposite extremities 2 and 3 similarly tapered and each provided with a metallic nose 4, comprising a shank 5, as shown by Fig. 4., fastened by a pin 6 to prevent it from working loose and also to strengthen the shuttle. A carrier or bobbin slot 5 is cut through the body 1 in a horizontal plane completely from one side to the other, and the top and bottom walls 6 and 7 are completely closed, with one exception, which will be presently explained. Adjacent one end wall of the slot 5 and projecting into the latter are carrier or bobbin holding devices which comprise a movable jaw 8 and a fixed jaw 9. The movable jaw 8 has a shank 10, which is slightly bowed and movably seated in a recess 11 in the adjacent portion of the body 1, said recess continuing into a slot 12, which extends through the bottom wall 7 and permits aT-head 13 to be disposed in movable relation thereto and project upwardly into the slot 5. The shank 10 is movably held in the recess 11 by a screw-rod 1 L, removably secured to a nut 15 at the opposite side of the shuttle-body, and closes a cavity or seat 16, in which a coiled spring 17 is located and surroundsa portion of the said rod 14, which acts to draw the shank 1O closely into the recess 11, but permits the movable jaw to have sufficient movement to serve its function. The jaw 8 ofitself is resilient, but offers a stiff resistance, which without reduction by the more sensitive nature of the spring 17 exerted thereon renders the same free to autom atically receive the head of a carrier or bobbin, which will be under the pressure of feeding mechanism of sufficient stress to overcome the resistance that may be offered by the normal adjustment of the said jaw. The T-head is form ed with opposite convex rounded ends 18, regularly merging into a central concaved seat 19, the latter being of a length about corresponding to that portion of the cylindrical surface of the head of the carrier or bobbin that rests therein, and the opposite curved ends 18 provide for an easy riding movement of the carrier or bobbin head into and from the seat 19. The fixed jaw 9 consists of a securing plate or member 20, having an angular supporting member 21, with an inturned flange 22, which is normally disposed over and in line with the working edge of the T-head 13 and has a central concaved seat 23 and opposite rounded ends 24:. The plate or member 20 is attached to the end wall of the slot 5 adjacent the position of the movable jaw 8, and the support 21 rests against the top wall 6, and by this means a portion of the shuttle which is ordinarily weakened is materially strengthened and splitting or fracture at said point avoided.

Having thus described the invention, what is claimed as new is 1. In a shuttle for looms, the combination of a shuttle-body having a carrier or bobbin slot entirely therethrough from one side to the other, and means for holding a carrier or bobbin in said slot consisting of a fixed jaw having an angular supporting member with a terminal inturned flange, and a yielding jaw with an inwardly-directed T-head and having a shank movably located in the body of the shuttle, the inner edge of the said T- head being in alinement with the edge of the inturned flange of the other jaw.

2. In a shuttle for looms, the combination of a body having a slot extending entirely therethrough from side to side for the reception or discharge of a carrier or bobbin, and means for holding the bobbin suspended within the said slot consisting of oppositelydisposed fixed and yielding jaws, the fixed jaw having an angular supporting member with a terminal inturned transversely-extending flange, and the yielding jaw provided with an inwardly-directed transversely-ex- JOHN C.
