A E Q F HENRY MARTIN BnowN, or PROVIDENCE, RHODE ISLAND, AssieNoa TO U. s. 'BOBBIN AND SHUTTLE 00., OF PRO- VIDENCE, RHODE ISLAND, .A CORPORATIQN OF NEW JERSEY.

' Loom-SH TTLE.

To alt whom. it may concern:

Be it known that I, HENRY MARTIN BROWN,

a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Loom-Shuttles, of which the following is a specification.

This invention hasmreference to an improvement in loom shuttles and more articularly to an j improvement in auxil ary threading devices for hand threading loom shuttles. i

In threading loom shuttles by hand the thread is first pulled .irom the bobbin over the hand threading mechanism of the shuttle. .As usually constructed the threading mechanism requires that the thread be do pressed between the end of the bobbin and the threading mechanism, so as to bring the,

thread into the entrance opening of the threading mechanism.

The object of my invention is to improve the construction of an auxiliary threading device for hand threading loom shuttles, whereby in drawing the thread from the bobbin over the hand threading mechanism to thread the shuttle the device is adapted to automatically depress the thread into the threadin mechanism and to be adjusted by turning t e device on itsaxis.

A further object of my invention is to construct an auxiliary threading device for hand threading loom shuttles integral, whereby the device is strengthened and supported at both ends in the throat of the shuttle by the side walls of the shuttle.

My invention consists in the eculiar and novel construction 'of an adjusta le auxiliary threading device adapted to be applied to any form of hand threading loom shuttle to facilitate the threading of the shuttle by details of construction as wil devicehaving be more fully set forth hereinafter and claimed.

Fig. 2 is a longitudinal sectional view through the delivery end of the shuttle, taken on line 2 2 of Fig.1, andFig. 3 is an enlarged transverse sectional view through theshuttle taken on line33of Fig.1. p

the bobbin cavity, '6 the throat, f the threading mechanism which may be any one hand i of the usual constructions, and g the adjustable auxiliary threading,device'located in' the throat (4 intermediate the end of the'bobbin 0 and the handthreading mechanism f. The shuttle'has the

transverse holes

6 and 7 extending-through the side walls one line with each other into the throat ,e and referably centrally between the end of the obbin c andthe threading mechanism f and slightly above the center line of the bobbin. The threading mechanismf has the entrance opening 8 for the thread which is manipulated by hand through the threading mechanism f to brin the thread out of the delivery eye 9 in t e side ofthe shuttle.

The auxiliary threading device g consists of a round pin 10 the length ofwhichj equals approximately the width of the shuttle and having the round ends 11 .11- in one of which is a transverse slot 12 and the flattened central portion13 in which is a lo itudinal slot- 14.and an inclined slit 15 exten' 'ng fromthe upper edge of the flattened portion 13 downward toward the transverse slot 12 into the end of the longitudinal slot 14, as shown in Fi 3'. The pin 10 is driven through the ho es 6 and '7 1n the side walls of the shuttle in a position to bring the flattened 'portion 13 in the throat e and to bring the inclined slit 15 in an upward position. The auxiliary threadin'g'device may now be adjusted to brin the slit 15-in'to the required position to catc the thread b inserting a screw-driver or other tool into t e slot 12 and turning the pin'10 on its axis. Q

In the operation of my improved auxiliary threading device the thread in threading the shuttle by hand is pulled ofijthe end of the bobbin over the auxiliary threading device gand over the threading mechanism f, as shown in light broken lines in Flgs. 1 and 2. The thread as it is pulled from the bobbin whips around the end of the bobbin in the direction'of the arrow shown in Fig. 3 and catches in the slit 15 in the auxiliary threading device 9 and" passes downward through the slit 15 into the longitudinal slot 14 The thread is, now depressed o1: forced downward by the auxiliary'threading device in the throat e andinto the entrance openin heavyjdotted lines in Fig. 1,- omfwhicli 204 longitudinal slot;

nipulated through the threading mechanism f and out of the delivery eye 9, as shownin.

v Fig. 2, to thread the shuttle. The auxiliary threading device 9 being laced between the I 5 end of. the bobbin 0 and t e threading rnechanisni-fwith the thread extending through the slot 14 in the auxiliary threading device prevents excessive ballooning of the thread i and'also exerts a slight friction or tension on- 10 th thread. i

Having thus described niy invention, I claim as new and desire to secure by Letters Patent 1. In a hand threading loom shuttle, an

I auxiliary threading device consisting of a pin.

' extending transversely through the sidewalls and throat of the shuttle and having a longitudirial slot and an inclined slit extending 4 from the side ofthe pin downward into the -'2. In a hand threading loom shuttle; an

In testimony whereof I have signed my name tb this specification in the presence ol two subscribing witnesses;
