FILLING-FEEDER FOR FILLING-REP-IJENISHING LooM's.

Patented Aug. 9, 1910.

Application filed February 2, 1910. Seria1 No.-541,418. i

To all whom it may concern:-

Be it known that I, EDWARD S. STIMPSON,

a citizen of the United States, and resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Filling-Feeders for Filling-Replenishing Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to. looms wherein the running shuttle is replenished automatically with filling by the insertion therein of a fresh filling-carrier or bobbin, the fillingcarricrs in reserve being held in a suitable feeder or magazine.

There are numerous instances in the prior art of filling-feeders arranged to support the filling-carriers at their butts and tips in such manner that they may be removed readily and transferred to the shuttle at the proper time, a well knowntype of feeder comprising essentially two connected and rotatable plates or heads arranged to cooperate respectively with the butts and tips of the carriers, Some of the feeders have been arranged With yieldingly-mounted butt-holders, while others haverbeen provided with yieldingly-mountcd tip-holders, one instance of the latter arrangement being shown in my United States Patent No. 755,252 dated March 22, 1904. Reference is made to this patent because in my present invention the tip-holders are very similar. tothose shown in said patent, and sofaras their functions are concerned they are substantially the same. V

My present invention, however, has for its object the productionof a filling-feeder embodying certain novel and valuable features of "construction whereby, notwithstanding the pressure of yieldingly-mounted' tip-hold .ers, the catching, pinchin or other interference with:.tlie filling-en s, as they are led from the -tips of the filling-carriers to a suitable end-holder, is absolutely and altogether eliminated. I 4 I The various novel features of my invention will lle fiilly described in the subjoined specificatioii and particularly pointed out. in

the following claims.

Fi'gurelis a front elevation and partial section of a filling-feeder embodying one form of my present invention, shown 1n connection' with other parts of the filling-replenside of the plate,

ishing mechanism of anautomatic loom of the well-known Northrop type; Fig. 2 is a partial inner side elevation of the plate or head of the feeder which supports the tips of the filling-carriers, one of the tip-holders being omitted to show the aperture in which such holder is seated; Fig. 3 is a similar 'view, but of the outer side of the plate, showthe backs of the tip-holders and their relation to certain portions of the-plate, tobe referred to.

Referring to Fig. 1, the circular plate a' of the filling-feeder, its hub a the stand A mounted on the breast-beam A; the fixed horizontal studa on which't-he" feeder rotates, the filling-end holding means, as th disk 6 and stud b carried'by and rotatabld with the feeder, and the transferrer f, may

be and are -all,substantially-as in my patent 'hereinbefore referred to, the plate a having a series of open-ended, circularly-arranged seats or pockets 2 to receive the butts ofthe filling-carriers. present invention the plate 3 at theouter end of the feeder is also circular, its hub 4 being rigidly attached to the hub a of plate a, so that said plates will rotate in unison the plate 3bein herein shown as provide with an outwar 1y flared peripheral flange -5 which presents a smooth and continuous annular surface to support the filling-ends, the outer edge 6 of the flan 6 also being continuous, as shown. Said p ate 3 thus has a smooth and continuous circular periphery, and'within it the plate has a series of ra- In. accordance with my dially arranged apertures, shown herein as elongated slots 7, which inpractice equal number to and are arranged opposite the seats or pockets 2 9f plate a.

As-shownin Figs. 1 and 2 the inner and outer ends ef the apertures 7 are curved, the outer ends extending into the base pf the flange 5, as at 8, the apertured portion ofthe. plate being thickened to form a "transverse rib 9 at the inner end of each of the aperturesfsee Figs. 1 and 3, on the outer while thelatter is shaped to present spring-seats lOspanning the apertures 7 between their ends.

Viewed from the outer side the springseats 10 form a continuous annular rib, as shown best in Fig. 3, and each seat on its inner face hasa circular depression or pocket 11 to receive one end of a spiral spring 8", Fig. -1.

end being shaped to present a deep transverse and slightlycurved groove h to receive and rock on the rib 9.

' When the holder is in position on the plate the cars it extendilaterally adjacent. the outer side of plate, at each side of the aperture 7, so that the holder can rock out ward on the rib 9 but can rock inward only l to an extent limited by engagement of the cars with the plate.- The spring 8 at its inner end enters a socket or recess h in theback of the holder,

opposite the spring-seat 11, the spring maintaining the holder pressed inward, as shown 'at the lower part of Fig. 1.

Upon its inner face the holder is thickened ath to form a substantially U-shaped seat h for the reception of the tip of the filling-carrier, the'spring s" acting with a longitudinal pressure upon the carrier to hold it firmly in position in the feeder, with its .butt in the opposite seat 2.

The thickened seat-forming parts 71 of the tip-holders ,project through the apertures 7 beyond the inner side of the plate 3, and as the seats open outwardly the tips of the fillling-carriers are readily inserted in the seatswhen the feeder is being loaded,

the springs SK yielding at such time to permit the requisite outward rocking movement of the holders on the ribs 9 as fulcra. v

As shown clearly in Fig. 2, and also at the upper part ofFig. .1, the outer ends of the holders extend into the outer ends of the apertures 7, and the parts 8 of the latter which extend into the base of flange 5 provide for a free and uninterrupted passage of the tips of the carriers down into the seats /z*.

The filling-end t is led from each fillingcarrier upward and outward onto the smooth and continuous annular face of the flange, over its circular, continuous edge 6 to the disk b' and thence to the holdingor fastening s ud 6 about which the end is wound,' in usual manner.

As will be apparent the flangeoverhangs and hoodsor shields the outer ends ofthe tip-holders, and the filling-ends are sup.- ported by the continuous outer face of such flange Well beyond the outer ends of the holders, so that it is impossible for the filling-ends to be caught, pinched or-held in any way.

By outwardly flaring the flange 5 the fill ing-end is led outward diagonally wit-h relation to the longitudinal axis of the fillingcarrier, in such a position that it is clear of the enlargement If for the tip-seat It, and with such directionoflead for the fillingend there is very little chance for it to pull filling-carriers, a connected plate having continuous,'circular periphery over which the filling-ends are led, a corresponding series of tip-holders movably mounted on the latter plate to engage and sustain the tips of the filling-carriers at the inner. face of i said plate and wholly within its continuous periphery, and springs to maintain the tipholders in operative position, the filling-ends being .led from the filling-carriers over the peripheral edgeof the plate and being held thereby out of contact with the tip-holders.

2. A filling-feeder comprising a plate adapted'to sustain the butts of a series of filling-carriers, a connected plate having a peripheral, outwardly-fiared flange presenting a smooth, continuous annular supporting surface for'the' filling-ends, said plate havinga series of elongated, closed radial slots whose outer ends terminate adjacent the base of said flange, and a series of yieldingly-sustained and individually-movable holders seated in said slots, to engage and sustain the tips of the filling-carriers at the inner side of said plate, the flange covering the outer ends of the holders and preventing contact of the filling-ends therewith.

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