DROP-BOX LOOM.

Application led October 7, 1924. Serial No. 742,172.

To ZZ ywhom t may Conce/m.'

Be it known that I, JOHN C. SHAMBow, a citizen of the United States, residing at lVoonsocket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Drop-l`lox Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to an imi'novement in drop box looms.

Plain drop box looms were provided with shuttles which had the delivery eye in the end of the shuttle nearer the selvage when the shuttle was boxed on the drop box side ot the loom. In this loom the butt of the bobbin was located at the opposite end of the shuttle from the shuttle eye. These looms were satisfactory in operation, but with the advent ot the use ot' t'eelers the weavers attempted to apply the teeler to the loom, inasmuch, however, as the feelers were mounted on the single box side of the loom and usually made their 'feeling movement in a direction outward trom the side ol the loom upon which they werey mountedr` such a leeler was not adapted l'or use with the shuttles employed in the loom. Consequently opposite hand shuttles were employed in the looms in order to adapt them to the use otl the l'eeler mechanism. This, however. although it brought the butt otl the bobbin in the right position for the teeler, resulted in the maloperation of the drop box, because it threw the eye. of the shuttle into the shuttle box on the drop box side ot the loom at, the end ot the shuttle remote trom the selvagge with the result that the yarn Vfrequently was caught between the bindt-r and the shuttle due to the lifting and falling oll the drop box. 'l`he present invention contemplates the use in a drop box loom ot the filling teeler type ot a shuttle ha ving` its eye at the same end as the butt of the bobbin and located iu a plane non-registering with the teeler hole ot the shuttle.

The present invention consists in the box loom hereinafter described and particularly detned in the claims.

In the accompanying drawings Fig. 1 is a diagrammatic view of a plain box loom embodying the invention: Fig. 2 is a plan,

and Fig. 3 an elevation of a shuttle for the looms.

The illustrated embodiment of the invention is described as follows The cloth being woven is indicated at 10, the selvages of the cloth are indicated at 11, and the single box 12 is shown at the one side and the drop box 13 at the other side of the loom. The loom is provided with a tilling feeler 14, stopping mechanism 15, and connections therebetween 16. A tilling fork 17 is provided, also connected with the stopping mechanism by the connections 18. The shuttle 20 employed in the leoni is provided with a feeler hole 21 through which the eeler enters the shuttle and feels of the yarn on the bobbin. When the yarn is exhausted to a predetermined extent, determined by the operation of the feeler, it stops the loom and the operative places a new bobbin in the shuttle. The shuttle is provided with a delivery eye 27 which is located in fixed position at the bobbin butt end of the shuttle, which is the end of the shuttle nearer the selvage when the shuttle is boxed on the drop box side ot' the loom. The yarn from the bobbin extends from the tip ot' the bobbin through the guide eye 22 into the tension cavity in the end ot' the shuttle where it may be passed through a tension device, it' desired, but which is shown as extending directly t'rom the guide eye 22 to the guide eye 23, which leads it from the tension cavity in the end of the shuttle to the top of the shuttle, or to a point near the top of the shuttle, where the yarn turns and enters the yarn tube 24 through which the yarn extends to the opposite end ot the shuttle. Here the yarn descends through the guide eye which may be a delivery eye in case the thread is delivered at this point into the groove 2G in the upper part ot' the front side ot the shuttle, or the eye 25 may be merely a guide eye, in which case the yarn extends down to the delivery eye 27 near the bottom ot' the shuttle, where it delivers the ya rn to the groove 28 at the lower front corner of the shuttle.

The position of the delivery eye is important, and is made non-registering with the position of the feeler hole in the shuttle, so that when the shuttle is boxed on the filling feeler side of the loom there is no possibility of the yarn being broken by the blow of the feeler against it as the teeler enters the shuttle. The filling fork 17 on failure ot' the wett indicates absence and operates the stopping mechanism to stop the loorn.

The shuttle herein described and claiined is particularly adapted for use in existing box looins provided with lilling teelers because the location ot the delivery eye of the shuttle on the side nearer the selvage when il is boxed on the dron box side ot the loom reduces wett breakage, and the location ot auch eye, in a plane non-registering with that ot the teeler hole reduces a V'nrther liability ot breakage by the teeler. Obviously the shuttle is ot advantage even in looms un- ]'novided with a teeler because of the reduction ot weft breakage due to the action ot' the binders on the drop box side of the loom.

Having thus described the invention, what is claimed is:

1. A box looin of the tilling teeler type having7 in combination. a lay having a single box on one end and a drop box on the other end, a 'feeler on the single box side ot the loon'i, a stop niotion, connections between the stop Inotion and the feeler, shuttles Yfor the boxes, each provided with a teeler hole and a yarn delivery eye located in the end ot the shuttle nearer to the selvage when boxed on the drop box side of the loom.

Q. A box looin ot the filling` feeler type having. in combination, a lay having a singlo box on one end and a drop box on the other end, a teeler on the single box side of the loont, a stop inotion.y connections between the stop inotion and the. lieeler. shuttles for the boxes, each provided with a Jf'eeler hole and and a yarn delivery eye in the end ot the shuttle nearer the selvage when the shuttle is boxed in the drop box side of the loont. said teeler hole and delivery eye being located in non-registeringv planes.

shuttle for teeler loonis having a body provided with a bobbin cavity. a teeler hole in the front et the shuttle. a delivery eye located at the bobbin-butt end ot' the shuttle, and yarn guiding means for eading the yarn troni the bobbin to the delivery eye, said teeler hole and delivery eye being lo cated in non-registering planes. i

4. A shuttle for Yteeler limnishavinga body provided with a bobbin cavitya a tceler hole in the 'front of the shuttle, a delivery eye located at the bobbin-butt end of thc shuttle and yarn guiding nieans 'tor leading the yarn tron: the bobbin to the. eye.

)t shuttle tor teeler loonis having a body provided with a bobbin cavity? a Vtreler hole in the front of the shuttle. a delivery eye located at the bobbin-bntt end of the shuttle and jfarn guiding ineens ir leading the yarn from the bobbin to the eye. prising a yarn tube extending alon the bobbin cavity to protect the yam troni contact with the yarn running oli the bobbin. i

(S. A shuttle for box looms ha\ ing a body provided with a bobbin cavity, a delivery eye tired at the bobbin butt end olI the shuttlc, and yarn guiding ineans tor lean/ling the yarn troni the bobbin to the eye.

In testimony whereof l have signed niy naine to this specification.
