\ W. PQSTRAW. LoM SHUTTLE AN`D BOBBIN THERBPOR. APPLTGATION I'IISEI) MAY 13, 1912.

1,053,678. PatentedFeb. 18, 1913.

curved and outwardly-flared, at 19, and also -with the faces 5 inclined downward toward the free ends 'of the jaws, as shown in Figs. 1 and 3. ySaid guides are at such a distance apart that the faces 5 on'the bobbin base will enter between them when the bobbin is transferred from the hopper, as shown in Fig. 4c, and obviously the guides will prevent any rotative movement of the bobbin as it passes into posi` .brought intoy proper position opposite the feeler-opening 14 of the shuttle.

By inclining as well as flaring the upper I ends. 19 of the guides I improve the corrective action of the latter upon the bobbin, while at` the same timew I provide for an VVeasier and smoother entrance of the fiatfaced portion of the bobbin base between theguides. j

The guides herein shown are very easily and cheaply made, as they can be cut or lstamped out of resilient plate metal and easily and quickly bent to the proper shape,

yand as the 'guides proper 16 are quite long and sustained wholly at their lower ends by the bends 2O a very desirablelateral resiliency or yieldingis assured Whenever necessary.

When the rings Q are ente i'ing the grooves 9 in the jaws the latter are pressed apart, as is usual, and so'separate the guides temporarily and very slightly, but,k the closing action of the jaws again brings'said guides into proper position with relation tothe dat faces on the base of thefbobbin.

Loeae'ze Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a loom shuttle having spring jaws adapted to engage and hold the rings on the base of a bobbin provided with opposite parallel and at faces beyond the rings, each jaw having an upright recess in its outer face, a Ushaped resilient guide carried by each jaw and having legs of unequal length,- the shorter leg being seated and fixedly held in the recess of the jaw, the guide passing under the jaw and having its longer leg up turned near the inner face of and extended above the aw, the upturned guide legs being opposite each other and substantially parallel, to coperate with andv receive between them the flat faces of the bobbin and positionit when inserted in the shuttle.

In a loom shuttle provided with spring-jaws adapted to engage and hold the rings on the base of a bobbin having beyond the rings a non-cylindrical portion, oppositely located resilient guides, each substantially U-shaped and having legs of lunequal length, the vshorter leg of each guide being 'attached tixedly to a jaw at its outer face and the longer leg' being extended upward adjacent ,the inner face of and above the jaw, said longer legs being shaped to fit against and position the interposed nonecylindrical portion of the bobbin and having their upper ends arcd outwardly and inclined toward the tips of the jaws, to'direct the specified portion of the bobbin into proper position between the guide legs when the bobbin is inserted in the shuttle.

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