LOOM WORKS, or woncn's'rnn,j vmssacnusn'rrs, .A- CORPORATION OF MASSACHU- snr'rs. V,

To all whom it may concern: p

Be it known that I, ErrA H. RYoN, a citizen of the United States, residing atjWaltham, in the county of Middlesexcand State of Massachusetts, have invented a new and: useful .Weft-Replenishing Loom, of which the following is a specification.

taken in a different position, and 1 This inventlon relates particularly .to a weft replenishing loom of the type having a movable weft carrier magazine inwhich the weft carriers are preferably arranged in groups and in which mechanism is provided for advancing successive groups of weft carriersrto. operative position. 1

This general type of weft replenishing mechanism is shown in prior Patents Nos. 939,326; 951,659; 1,032,709 and"1,045,- 443. Such mechanism isicommonly used on dropbox looms using a plurality of shuttles, and a particular weft carrier in theoperatively positioned group is moved to transfer position whenever the corresponding shuttle becomes active. Theimagazine is advanced to bring another group to operative position whenever any weft carrier in a group or a i t 26 1) positioned in the camjgroove 27 of 'a side cam 28 mounted 'on'the usual bottomor cam shaft 29. This'cam makes 1 particular ferred. I

It is the object of my present invention to weft carrier in a groupis'trans- 7 provide improvedactuating devices forthe transfer and feeding mechanism by means 7 of which the several operations maybe per formed in a reliable and accurate manner.

W1th this general ob ect in view, an 1m- .portant feature of my invention relates to the provision of a single actuating cam and a single lever movedflthereby, togetherwith Another feature relatesto the provision of p sociated with the magazine, and a worm engaging therewith and movable longitudinallyf as well as angularly. The worm and a storage spring for! advaneing the magazine whenever the spring is" tensioned and Y released by the control mechanism. p My invention further relates toarrangements and combinationsof parts hereinafter 7 described and more particularly pointed out v in the a pended claims.

The transferrer 13 is pivoted at 15 tothe magazine frame. A de-, pending hook 16 is pivoted at 17 c to the transferrer l3 and is under the control ofa weft detecting member or feeler 18 projecting'rearwardly tointermittently engagethe 'ac'tive weft carrier. 1 When the hook 161is operatively located, as shown in Fig. 1, it is positioned for engagement ,by'the headf 19 of a plunger20 slidable vertically in a fixed bearing.21. The plunger 20, is connected byarod 22 to an actuating'lever 23 pivoted 1 at 24 to a bracket 25 fixed to the loom.

A member 38 is pivoted to move freely 36 on its-periphery and 37 on its outer slde surabout the of the stud 33 and is pro vided with two arms 39 and 40. The arm 39 is provided wlth a sprlng plunger 41 adapted to engage one of the notches 37in" the disk 35, while the arm 40 constitutes a striker adapted to engage and lift a lock ing latch 42 normallyseated'in one of the notches 36. The latch 42 is mounted upon a fixedpivot 43 upon which is also mounted a second or hold-back latch 44 adapted to engage another one ofthe notches 36 and to prevent backward movement of the plate as the latch 42 is raised. A coil spring 45' positioned between portions of the latches 42 and 44 yieldingiy forces each of the latches into engagement with the notches 36.

A vertically movable bar 46 is pivoted at 47 to the arm 39 of the member 38 and is provided with a lug 48 which is at times engaged byan offset lug 49 formed on the end'ofthe lever 23. Normally, however, the lugs are out of engagement, as is shown in Fig. 1. A rod or link 50 is pivoted at its upper end to the transferrer 13 and at its lower end extends through an opening in the upper end of the bar 46. v A spring 51 is positioned between theheaded lowerv end of the rod 50 and the offset upper endof the bar '46. The lever 23 is further provided with an upward extension 52 andan adjusting screw 53 adapted to engage the -bar '46 as the lever 23 is swung upward. A heavy coil springf54 encircles the stud 33 and. is connected at one end to a collar 55 fixed to said stud and at the other end to the angularly movable member 38.

I Having described the details of construction of my improved actuating mechanism, I will now describe its operation. The plunger 20 and headf19 are reciprocated vertically at every alternate beat of the lay, and upon weft exhaustion the hook/16 is positioned for engagement by the head 19. The transferrer is thus actuated to insert" a fresh wveft carrier and through the rod "50 the transferrer moves the bar 46 to bring its lug 48 into the pathof the lug 49 on the lever 28, as shown in Fig. 2. As the lever 23imoves upwardly, the member 38 is moved about the axis of the stud 33 and, against thetensionof the spring 54. Such movement of the member 38 permits the spring plunger 39 to engage the next notch 37 in ,notch .36. @fthe stop screw 53 in the upward extension 52 of the lever 23 engages the bar '46 and the disk35 and also causes the arm40-to disengage the locking latch 42 from the As this disengagement occurs,

forcesit rearwardlyuntil the lugs-48 and .49 are disengaged, The member 38jthen 7 makes a partial revolution under the influence of the spring 54, advanoingthe disk 35 and beveled gear 32, and thus feedlng the magazine through the beveled pinion 31 and parts associated therewith.

As the disk 35 revolves, the latch 42 engages. the next notch 36 and the feeding unnecessary for the magazine to'make sudden or rapid'mov'ements.

Having thus described my invention, it is' evident that changes and modifications. can be made thereinby those skilled in the art Without departing from the spirit and scope thereof as set forth in the claims, and I do not wish to be otherwiseilimited to the details herein disclosed, but what I claim is 2- 1; In a weft replenishing loom, a weft carrier magazine, feeding means to advance a fresh weft carrier in said magazine to transfer position, transfer mechanism, a single continuously moving cam, andconnections through .whichsaid cam controls the movements of bothsaid transfer mechanism and said feeding means. 1
