LOUIE-SHUTTLE.

Specification of Letters Patent.

Patented Dec. 22, 1914.

Application filed September 25, 1913. Serial No. 791,762.

To all whom it may concern Be it known that I, HUDSON W. Harms, a citizen of the United States, residing at Millbury, in the county of Worcester and State of Massachusetts, have invented a new and useful Loom-Shuttle, of which the following is a specification.

This invention relates to a loom shuttle and more particularly to improved hand threading devices for such a shuttle. These devices comprise two essential elements, a horizontally extending shuttle eye and a vertically positioned thread retainer, these elements cooperating to permit easy threading ofthe shuttle and to guide and securely retain the thread in its passage therefrom. In accordance with the usual practice, 1 form the shuttle eye from sheet material pressed into substantially cylindrical shape and disposed within a transverse passage in the shuttle body. A horizontally disposed return slot communicates with the transverse passage and provides for the entrance of the thread therein. In order to prevent the thread from thereafter escaping through the horizontal slot, 1 provide the common recessed or cut-away portion upon'one edge of the sheet material and a cooperating projecting tongue upon the other edge, these parts overlapping to confine the thread within the eye. The thread as it is drawn from the slot into the eye passes over the projecting tongue and it is therefore, necessary to provide clearance outside of said tongue to permit the passage of the thread. Such clearance has been heretofore provided in several ways, no one of which has been found entirely satisfactory. Eyes have been formed in which the material of the tongue was reduced in thickness, thus involving an additional milling operation with increased eX pense. In other forms, the projecting tongue has been bent downward into the cylindrical opening within the eye, but this construction tends to obstruct the eye and the varying resilience of the material makes it difficult to secure uniformity in positioning the tongue. In a third form, the tongue is located at the end of the eye and the wood of the shuttle body is cut away outside of the tongue, thus avoiding the defects previously noted but permitting easy rentrance of the thread into the clearance space and the horizontal slot.

It is one of the objects of my invention to provide an eye which shall avoid the defects and objections herein set forth and this I accomplish by forming the tongue intermediate of the ends of the eye and concentric with the body of the eye, and by providing a recess in the shuttle body removed from the ends of the transverse passage and cooperating with the tongue to provide clearance thereover.

A second object of my invention is to provide an improved thread retainer into which the entrance of the thread shall be assured and escape from which shall be essentiallv impossible.

\Vith these objects in view, the invention comprises certain arrangements and combinations of parts hereinafter described and more fully set forth in the appended claims.

A preferred form of my invention is shown in the drawings in which- Figure 1 is a plan view of a shuttle embodying my improved device: Fig. 2 is a side elevation of the front end of the shuttle: Fig. 3 is a transverse sectional view taken along the irregular line 3-3 in Fig. l, looking in the direction of the arrow: Fig. 4 is a horizontal sectional view taken on the line 4:'-% of Fig. 2: Fig. 5 is a perspective view of my improved shuttle eye; and Figs. 6 and 7 are perspective views showing the exit and entrance sides, respectively of my thread retainer.

A loom shuttle 10 of common form is shown in Fig. 1 in which a cop 11 is mounted upon the spindle 12 in the usual manner. The front end of the shuttle is provided with a vertically disposed threading slot 13 communicating with a horizontally disposed slot 14, as shown in Fig. 2. The horizontal slot provides entrance into a transverse cylindrical passage 15 within which is secured the threading eye 16. The eye 16 is formed from sheet material which is pressed into substantially cylindrical form and is provided at one end with an outwardly turned flange 17 adapted to be received in a slot 18 in the shuttle body thereby securing the eye against rotation in the transverse passage 15. The eye 16 is also provided with an entrance opening 19 and with a pair of separated lips 20 having outturned end portions also received in the slot 18. The opposite edge of the sheet material forming,

the eye supports an obliquely disposed tongue 21 which projects within the space between the separated lips 20. The tongue 21 is formed concentric with the axis of the c eye 16 thus permitting a clear cylindrical opening 22 therethrough. In order that the tongue 21 is so located that it will underlie the recess 23 while the lips 20 upon either side of the tongue rest against the cylindrical portion of the passage 15, and have their end portions secured in the slot 18.

In the actual construction of my improved shuttle, a T-headed-milling cutter is inserted within the passage 15 and when it has reached a point properly removed from the extremity thereof the axis of the cutter is shifted relative to the axis of the passage 15 to provide the eccentric recess 23 which is shown in the drawings.

A vertically disposed cylindrical recess 2% is provided in the shuttle body, underlying the vertical threading slot 13, and within this recess is secured the thread retainer 25, the retainer having a projecting flange 25 received in a slot in the shuttle body and preventing relative rotation therein. This retainer is formed of sheet material bent to substantially cylindrical shape and is provided with an entrance slot 26 and an exit opening 27 through which the thread passes shown at 28, the space between the extreme upper edges thereof being greater than the width of the slot 13 so that the thread in entering the thread retainer through the slot 13 will strike the beveled edges 28 and cannot lodge upon the upper end ofthe thread retainer. One edge of the sheet material forming the retainer isrecessed at 29 and a tongue 30 upon the opposite edge of the sheet material projects into the recess and serves to retain the thread within the exit opening 27. The tongue 30 is bent slightly inward to provide clearance for the entrance of the thread into the retainer.

In the operation of threading my improved shuttle, the cop is placed upon the A spindle as is usual and the thread is drawn forward into the slot 13 and rearwardly through the slot 14 into the opening 22 Within the shuttle eye. These operations serve to introduce the thread first into the thread retainer 25 and thereafter 'into the eye 16. The principal "function of the thread retainer is to prevent the catching of the thread upon the edges of the slot 13 which sometimes-occurs from the ballooningof the thread as it leaves the cop.

It is obvious that many'modifications of my device may be made bythose skilled in the art without departing from the spirit and scope of my invention and I do not wish to be limited to the precise details disclosed herein, but

What I do claim :is

1. A loom shuttle comprising a body having a transverse passage therethrough anda substantially cylindrical sheet metal eye secured in said passage, said passagebeing formed cylindrical in its end'portions and having a recessed eccentric portion intermediate its ends, said eye having a recess in one edge of the sheet material at a point removed from the end of the eye and having an obliquely disposed tongue concentric with the axis of the eye projecting into said recess in the sheet material and underlying the recessed portion ofthe transverse pas sage.

2. A loom shuttle comprising a body having a transverse passage therethrough and a hand-threading eye secured in said pas-- sage, said passage being cylindrical throughout the greater portion ofits length but having a laterally off-set recess intermediate its ends, and said eye being formed from sheet material and having a cylindrical body with a pair of separated lips formed in one edge of said sheet material and an obliquely disposed tongue projecting from the other edge of said sheet material into the space between said separated'l-ips, the end of said tongue underlying the off-set recess of the transverse passage and being spaced from the end of the eye.

3. A loom shuttle comprising a body having a longitudinal vertically disposed slot and a vertical recess within said slot but below the upper end thereof, and a thread retainer secured in said recess and comprising a vertical tube having an entrance slot and an exit opening formed therein and a projecting lip overlying said exit opening and crossing said vertically disposed slot, said entrance slot having oppositely disposed .side walls beveled at their upper ends, the

upper edges of said beveled walls being separated by a space greaterthan the width of said threading slot whereby free entrance of the thread into said retainer is assured,

4. A loom shuttle having in combination a body having a longitudinally verticallydisposed slot and a cylindrical vertical recess within said slot but below the'upper end thereof, said recess being of greater diameter 7 than the saidslot, and a thread retainer secured in said recess and comprising a vertical tube having oppositely slotted sides and having a lip projecting from one side of one of said slots and extending transversely my hand, in the presence of two subscribing across the vertically disposed slot in the Witnesses.

shuttle body, said lip and said vertical slot 7 cooperating to permit free entrance of the HUDSON HAKES' thread into said retainer but effectively pre- Witnesses: venting its escape therefrom. IDA A. HOBART,

In testimony whereof I have hereunto set IRA N. GODDARD.
