"this moment an empty cavity presents itself at the base of the passage 6 into which a In their travel with the barrel and at the base thereof the pirns are supfrom which they escape when expelled by the hammer 2. At each movement of the lever'o the lever rocks and the dog I) releases the ratchet wheel which acted upon by a spiral spring wound around its shaft is free to rotate in the direction indicated by the arrow 00 if the finger b is liberated by the escape of the last pirn from one of the grooves a a The lever c is lifted by a roller 0* mounted upon the lay of the loom and its pawl c maintains it cooked for the ratchet 0 ready to drive the barrel assoon as the hammer z expels the shuttle located at its base. The pirns in falling into the cavities and the recesses in the barrel 0 and the plate 0 engage their plugs e in the pincers F which are opened at this moment by the boss f. As the barrel rotates, the pincers close after having escaped from the boss f seize the plug 6 and draw the latter out therewith as the said pincers F are displaced longitudinally .hpon the shaft f, by the helicoidal groove in the drum f, so that the plugs e occupy fnsuccessiori the positions 3, 4 and 5 and finally reach the position 6. In this position the weft thread (Fig. 3) is arranged in line with the path when the pirn is inserted in the shuttle the After having traversed 7 the arm f of the another boss f which and the latter then falls into, a receptacle arranged below. i

What I claim and desire to secure by Letters Patent of the United States is 1. A weft replenishing device for looms, comprising a rotary feed cylinder adapted to carry a supply of pirns, gripping devices for drawing out in succession from the several pirns a reserve of thread arranged at the end of each thereof, and cam means for moving certain of said gripping devices serially and simultaneously in extension of the pirns to draw out said reserves of thread for the purpose specified.

of the shuttle, so that 2. A weft replenishing device for looms,

comprising an automatic feed cylinder adapted to carry a supply of pirns in combination with a series of pinccrs arranged at one end of said feed cylinder and rotating therewith, means to longitudinally displace said pincers during said rotation and means to open the sameat the beginning and at the end of their longitudinal displacement, for the purpose described.

3. A weft replenishing device for looms, comprising an automatic feed cylinder adapted to carry a supply of pirns in combination' with a at one end of said cylinder and rotating therewith, and a stationary member with helicoidal guideway engaged by said pi'ncers whereby the latter are longitudinally dis placed, substantially as described.

4. A weft replenishing device for looms, comprising an automatic feed cylinder adapted to carry a supply of pirns in combination with a series of pincers arranged at one end of said cylinder and rotating therewith, and a stationary member with helicoidal guideway engaged by said pincerswhereby the latter are longitudinally displaced. said pincerscomprising a fixed arm provided with a claw engaging said helicoida! guideway and a movable arm pivoted to said fixed arm and a spring tending to keep said pivoted arm closed upon the fixed arm, substantially as described.

5. A weft replenishing device for looms. comprising an automatic feed adapted to carry a supplyof pirns in eombination with a series of pincers arranged at one end of said cylinder and rotating therewith, and a stationary member with helicoidal guideway engaged by said pincers whereby the latter are longitudinally displaced. said pincers comprising a fixed arm provided with a claw engaging said helicoidal guidcway and a movable arm pivoted to said fixed arm and a spring tending to keep said pivoted arm closed upon the fixed arm, together with stops arranged at the extremities of said helicoidal guideway adapted to engage and temporarily open said pivoted arm, for the purpose described.

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