ATTORNEY WILLIAM J. MAL ONEY, 0F ANSONIA, CONNECTICUT.

NARBOW-FABRIG-LOOM SHUTTLE.

Application filed August 4, 1921.

To all whom it may concern:

Be it known that I, WILLIAM J. MALONE-Y, a citizen of the United States, residing at Ansonia, county of New Haven, State of Connecticut, have invented an Improvement in N arrow-Fabric-Loom Shuttles, of which the following is a specification.

This invention relates to loom shuttles and particularly narrow fabric loom shuttles such as are used for the manufacture of Suspender wedding, tapes, ribbon, surgical webbing, garter and armband webbing, elastic frill web and so forth.

An object of the invention is to yieldingly place the filling or weft yarn in the webbing or ribbon, so as to break the sudden throw of the thread: in the shuttle against the edge ofthe web. I g

It is also an object of the invention to provide a shuttle which may be adjusted to give a tight or round edge on one side and a loose or frill edge on the other side.

It isa further object of the invention to provide a shuttle which may be adjusted to make two round edges exactly alike.

In my preferred construction these objects are accomplished by mounting a shuttle eyes-or guide in a ball yieldingly mounted in the grooved front part of the shuttle and also providing adjustable means by which the ball and the eye can be made stationary at any point within the slot in the front partof the shuttle.

In connection with a more detailed description of the invention reference is had to the accompanying drawings illustrating the. preferred form thereof, and in which;

Fig. 1 is 'a plan view of a shuttle comprising my invention;

Fig. 2 is a transverse central section thereof;

r Fig.- 3 is a longitudinal central section;

Fig. 4: is'a front edge view;

Fig; 5 is a detail perspective view of one of the adjustable stops for the ball, and

Fig. 6 is a sectional View of the ball.

In the form of shuttle illustrated, the body 10 thereof is provided with a bowed front portion 11, the usual guide 12 for the shuttle block, and the rack 13. Within the opening formed by the base and front portions of thebody is mounted the bobbin or spool 14 which carries the supply of filling thread, it being mounted on the wire spindle 15 removably mounted in the shuttle in reicesses at the opposite ends thereof in the Specification of Letters Patent.

Patented Apr. 4, 1922.

Serial No. 489,789.

opposite ends of a spool or bobbin are the guiding eyes 16 and 17 secured to the ends of light springs 18 and 19 mounted within the body. .Mounted in back of the bobbinis av brake 2O bearing against the thread and pivotally mounted in the body at 21. This brake is pressed against the thread by means of a spring 22 and preventsthe thread unwinding too rapidly. The construction so far described is usual in thistypeof shuttle.

The front curved or bowed portion of the body is provided with two slots 23 and 24 and between the two within the front portion is mounted the ball 25. This ball fits loosely within the body portion so that it is free to turn therein and maymove back and forth. A guiding tube 26 extends diagonally through the ball to form a guiding eye-for the thread. This tube is secured in the ball by any suitable'means such as set screw 27. On substantially opposite diagonal points the ball is provided with eyes 28 and 29 to which are secured light coil springs 30 and 31, these springsextending through suitable guiding tubes 32 to the base of the body portion where the other ends of the springs are firmly secured by any suitable means as wedges or plugs 30. WVithin the bowed front portion of thebody, on opposite sides of the ball, are adjustably mounted clamping and limiting rings 33 and 3 1. These rings are preferably made of wire provided at one side thereof with two spaced parallel supports 35 bent substantially at right angles to the body of the ring and they may be strengthened by soldering at the bend b if desired. These supports are adapted to straddle screws 36 and 37 threaded into the inner wall of the closed portion adjacent the opposite ends of the slot 24. Beyond the screws, the body is provided with two openings 38 through which the'free ends of the supports 35 may extend. -By loosening either or both of the through the eye 39, yieldingly mounted guiding eyes 16 and 17, and then through tube-26 from the inner end thereof-emerging away from the ball allowing it to yie from the outer free end at the front curved portion of the shuttle.

In operation, the clamping and limitlng rin 33 and 34 may be adjusted to any position according to the effect desired. If they are spaced away from the ball 25, as shown in Fig. 3 of the drawing, the ball will be yieldingly mounted within the bowed front portion 11 by means of springs 30 and 31, and a tension either to the right or left will turn the ball accordingly or may move the ball bodily against one of the rlngs 33 0134 according to the amount and direction of the pull thereon. It will be apparent that, if one of the rings 33 or 34 is spaced a greater distancefrom the central or neutral position than the other, that the guide or eye 26 will yieldmore when the shuttle is reversed at one endvof its travel than at the other, thus giving different effects on the opposite edges of the fabric. It will be clear from this that, under the normal conditions where a stationary guide corresponding to the guides 26 is employed, nonuniform edges are liable to be produced. With my form of shuttle, adjustments may be made to counteract the unequal conditions to be I met.

Again, if it is desired to form different edges on the opposite sides of the fabric, as for instance, a frilled edge on one side and a round edge on the other, one of the rin s 34 may be advanced to prevent the shutt e ball 25 moving toward that side of the shuttle, but the other ring may be s aced h toward this side.

Further, the shuttle may be employed the same as the present shuttles in which the guide or eye 26 is stationary in the center. of the shuttle. This may be accomplished b moving the rings 33 and'34 toward the ba 1 25 an clamping it in the central position. It will also be apparent that by the same means the ball 25 may be secured stationary at any point within the curved front 11 by moving it to the position desired and then clamping it therein by means of the rin 33 and 34. An arrangement such as this will give a tight ed e on one side and a loose edge on the other ecause, as the guide 26 is not in the center of the shuttle, the same throw is not obtained on the two sides ha i 1 cause the shuttle travels the same distance each time.

- In forming a frill edge with the shuttles at present employed in which the central guide or eye is stationary, an edge wire is usually required to hold out the e ge while weaving because of the hard pull of the stationary guide or eye in said shuttle. With shuttles embodying the present invention, however, this wire is unnecessary in making a frill edge because as the eye or guide 26 is yieldingly mounted, it breaks the sudden throw of the thread in the shuttle against the edge of the web. At the same time the filling is placed in the web at the same tension as it would with a stationary guide because of the tension springs 18 and 19.

Although I have disclosed the invention as embodied in the type of shuttle shown it may be used equally as well in a circu r shuttle.

Having thus set forth the nature of my invention, what I claim is:

1. A loom shuttle comprising a body, a guide for the thread as it leaves the shuttle mounted in the front portion of the body, and means allowing adjustment of said guide longitudinally of said front portion and for securing it in adjusted position.
