. reversal of said jaw-carriers.

indicated by the The lugs 5 and 8 of-each jaw constitute intles andare loosely inserted in the eyes 15 and 14 respectively, in assembling, and before the eyes are closed by the adjacent shuttlc-wood, so that each jaw is pivotally connected with its carrier and can swing toward or from the center of the shuttle, such movement being limited bythe lug 6 of a jaw enteringthe recess 16 inthe bend 11 of its carner.

Viewing Fig. 4 it will be seen that the right hand jaw 3 is fulcrumed at its upper edge and the op ositely located, left-hand jaw is fulcrume at its lower edge, the: jaws being yieldingly held in substantial parallelism but inclined with relation to the walls of the' shuttle.

Il have herein shown the yielding control effected by springs 26 held inthe openings 13 and bearing against the free, adjacent portions ofthe jaws', the springs being of any suitable character, such as blocks of rubber, though I do not restrict myselfthereto.

j Referring to Fig. 4 it will be seen that the upperI edge of the left-hand jaw may swing outward to Widen the opening between the jawsto admit the head of an incoming bobbin, the operative osition of the head being otted circle 27,l and the lower edge of the right-hand jaw can move outward, or to the right, Fig. 4, when a bobbin is ejected. This arrangement rovides for a very easy insertion of a bob in into holding position between the jaws, reducing the power required to effect such insertion,l

and also makes the ejection of a bobbin easier, while reducing the strain upon the various parts of the holding means and the A shuttle itself.-

As the jaws are precisely alike they are interchangeable, as are the carriers, and both parts can be easily and chea ly constructed .from strap metal of proper c aracter.

I do not restrict my invention yto the construction and arrangement described in detail herein, as the same is but one practical embodiment 4of my invention and may be varied in different particulars without departing `from the scope of my invention as setl forth in the claims annexed hereto.

Having fully described my invention,what

' I claim as new and desire to secure by Letters Patent is 1. A loom-shuttle adapted for the automatic insertion of a bobbin, having se arate jaws mounted thereon to engage and old a bobbin between them, independent pivots for the jaws, and means co erating with the jaws to maintain them yie dingly in OP- s erative osition.

'2..11 oom-shuttle adapted for the automatic insertion of a bobbm, having opposed.

Aindependently movable pivoted jaws thereon` a bobbin `and constitutethe sole supporttherefor, and` fulcra for said jawssubstantially parallel to the longitudinal axis of the shuttle.

4. A loom-shuttle adapted for the automatic insertion of a bobbin, having opposed, independently movable jaws to yieldingly engage and hold a bobbin, one of said jaws being pivotally sustainednear the top, and

seplarate means to pivotally sustain the ot er jaw near the bottom of the shuttle.

5. Bobbin-holding means for loom-shuttles, com rising relatively fixed carriers, oppositely ocated bobbin-engaging jaws piv- 'otally mounted on the carriers, and yielding means for and to normally maintain each jaw in 'o erative position.

6.- Bo bin-holding means for loom-shuttles, comprising oppositely located bobbinengaging jaws, means to pivotally support said jaws, one adjacent its upper longitudinal edge and the other adjacent its lower edge, and means acting at the free edges of the jaws "to maintain them yieldingly in operative osition.

7. In a oom-shuttle having a bobbin-receiving opening, opposite holding-jaws having their inner faces normally in parallelism and inclined with relation to the walls of the bobbin receiving opening, and means to maintain the jaws in yielding engagement with a bobbin.

8. In a loom-,shuttle having a bobbin-receiving opening, opposite pivoted holdingjaws having their inner faces normally in parallelism and inclined with relation to the walls of the bobbin-receiving opening, fulcra for the jaws substantially parallel to the longitudinal axis of the shuttle, and means to maintain the jaws yieldingly in operative position, the jaws constituting the sole support for the bobbin.

9. In a loom-shuttle adapted for the 'automatic insertion ofa bobbin, two opposed and movable jaws to engage and hold beed on vthe carriers faces shaped to engage and hold the head l and means to limit movement of the jaws.

stantially parallel carriers extended tudinally into the opening, holding jaws pivotally mounted on the carriers, and yielding means interposed between the jaws and carriers to maintain the jaws in operative position.

l2. in a loom-shuttle adapted for the automatic iiisertion of a bobbin, opposed, independent holding jaws to coperate with the bobbin, a separate 'pivotal' support for each jaw adjacent one ed e thereof, and substantially parallel to' t e longitudinal axis of the shuttle, and means acting on the hee edges of the jaws to maintain them yieldin ly pressed inward- 13. n a loom-shuttle ada ted for the al1- tomatio insertion of a bobhin, two oppositely located and movable 'holding jaws, a separatel and independent pivot for each jaw, means to act n on the jaws and maintain them yielding y in en a ement with the head of a bobbin inserte t erebetween,

longi- 14. Bobbin holding 'means for loom-shuttles, comprising two like and reversely po- I sitioned jaw-carriers, jaws pivotally mountl and having their inner I of a bobbin,.and means interposed between each carrier and the jaw mounted thereon to yieldingly maintain .the jaw in operative position.

15. Bobbin holding means for loom-shut tles, comprising two opposed like. jaws reversely p1voted, carriers rigidly mounted on the shuttle, and on which the jaws are pivoted, and yielding means to control the movements of the jaws.

16. Bobbin holding means for loom-shuttles, comprising two like and reversely positioned j :Lw-carriers, each having a flat base an wit 'eyes, `a separator interposed between the bases, means to hold said bases and separators rigidly to the shuttle-body, a jaw having pint es pivotally mounted in the eyes of each carrier, control pivotal movement of the jaws.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
