Serial No. 415,629.

repleiiishing looms, andy particularly'to that class of looms which have a magazine coma prising two or more Guide-ways or coinvpartments, at one end of the loom, and shifting or change shuttle boxes at the other end of the loom, and shuttles with fillingvof different colors or characters, corresponding to. like fillings in the compartments of the magazine. p

ln my aresent improvements lf have located the filling detector on the same end of the loom as the magazine, and when tlie'iilling detector acts as it detects the practical or substantiall exhaustion of filling in the active shuttle as the lay comes forward, and causes a movement towardy conveying the filling carrier under the transferrer, a change of filling then takes place in said shuttle when it next comes under the transferrer, which may occur during the second forward movement of the lay, in case the same shuttle remains active, or if said shuttle is changed when returned to the shifting shuttle box end of the lay, then the movement caused by the action of the lliug detector 1 ferrer.

will be incomplete or held partially completed, until'said shuttle is brought into action again. rlhis movement, caused by the filling detector, I herein term a preliminary movement, and in my improvements as herein shown and described l have caused said preliminary movement to be the movef nient of the lowest filling carrier in a compartment selected by a pattern indicator of a pattern chain, or other pattern surface, instead of by the movement' of the shifting shuttle box mechanism, as customary heretofore. The preliminary movement referred to may he made by other suitable mechanism, coiiperating with the conveying of a filling carrier to a position under the transl`his preliminary movement sepa rates the lowest filling carrier from a series of filling carriers, and after this separation said filling carrier is under the control of another indication of the pattern surface, to he immediately conveyed to a position under the transferrer, in case the saine shuttle remains on the race-way for the followingv picks of filling, but in case the shuttle box pattern chain determines that another shuttle having a different character of filling, is to becomeactive, then the filling carrier which has had its preliminary movement, is held in abeyanee by the pattern indicating surface controlling the movement of said filling carrier, until the continued movement of said pattern surface determines that the same shuttle is to again become active, whereupon said filling carrier is conveyed to its position underthe transferrer.

By controlling the iconveying of a lling carrier from its compartment, bya pattern indicating surface, instead of the shifting shuttle box mechanism, as customary heretofoie, il am enabled to determine in ad Vance, whether the lling carrier is toloe conveyed to-its position under the transferrer in the same period of the movement of the lay following the indication, which the shifting of the active shuttle, if changed, would occupy, or whether the conveying shall he delayed and the shifting of the active shuttle take place. By the conveying of the filling carrier in this earlier period 0f the movement of the lay, which was heretofore utilized by an indication by the shifting shut-tle box mechanism for the conveyi ing of the lling .cai'iier, more time is taken for the filling carrier to be conveyed, and adjust itself in its transferred position,

and the loom can he ru'n at a greater .speed f.

than heretofore.

In my present improvements I have shown a filling detecting device of a type comprising a solenoid and magnetized feeler.. My invention consists incertain novel features of construct-ion of my vimprovements as will be hereinafter fully described.

I have only shown in the drawings detached parts of a -weft,repleiiisliing loom of the class referred to, with my improvements combined therewith, sufficient to enable those skilled in the art to understand the construction and operation thereof.

Referring tothe drawings :-Figure l is an end view of parts of a loo-in of the class ioo oaaaee against the upperendvv of the yoke-shaped guide 4l, and at its lower end against the extension 31a, and acts to raise said rod 40 Iv40 is guidingly held in the upper slotted end of an extension .43 on a swin m0 frame 43,A having hubs 43 loosely mounted on the horizontally sliding rod 28, to move with x said rod as it is moved longitudinally, `see Figs. l', 6, andl 7. The longitudinal movement of said rod 28 is, in this instance, as above described, controlled through eonnections to the second pattern indicating sur face 22, see Fig. l. ln this 'instance as there are only twoguide-ways or compartments 44 in the magazine 44, for two sets of filling carriers 9', there are only two positions -of the longitudinally moving rod 28, said positions caused by the rolls or tubes, or other indicating surface on the pattern chain 22a. 4

The upper end 40 of the rod 40 is madel bent or hooked, as shown, and is adapted toe age either one of the two arms 45, and- 46, Ienitending out from the hubs 45', and 46',

i direction.

respectively, loosely mounted on a transverse shaft 47, having bearings at 47 on the back of the magazine 44, see Fig. 6. Springs 45a .and 46a are `connected with ther hubs 45 and 46', respectively, to move said hubs. in one rl`he` hub 45 of the arm 45 has a downwardly extending arm 45l thereon, termed a retaining arm, the lower end ot which is notched and adapted to extend over the upper end of a verticallymoving rod 48, which moves Ain guides on the back of the magazine 44, and has a spring48 there` on, see Fig. 6. The lower end of the rodr48 has an elongated opening 48 therein to rebeive a pin 49' on a rocking cradle or support 49, see ligs.- 6 vand 7. The I rocking cradle 49 is constructed substantially the same as the rocking cradle or support described in the application for Letters Patent, Serial No. 298,939, above reterred to. l'lhe hub 46"'oif' the arm 46 has l a downwardly extending arm 46, termed a Y end, see F ig. 7, which is adapted to extend' retaining arm, .avhich has .a notched lower over the verticallylmoving rod 48a, having a spring 48a thereon, and moving in guides said rod 40, against the action of the helically coiled expansionspring 42, see Fig. 7, and will rock one ot the arms 45, and 4G, according to the position of the upper end 40 ot the rod 40, relatively to the arms 45 and 46, and in case the rod arm 46 is operative, will move the downward extension 46 away. from the vertically moving rod 48a, see Fig. 7, and allow the helically coiled expansion spring 48?, encircling the rod 48a, to act to raise said rod'and rock the cradle 49, and allow the lowest bobbin 9 in i compartment 44 to have its preliminary move* ment, and drop down into the hollow part of the cradle 49a, as shown in Fig. 4, and be held there preparatory to being conveyed to a' position under the transterrer. The rockA ing movement of the cradle 49 will cause the pin 49a thereon, see Fig. 7, to engage a projection 43 on the arm 43 on the swinging trame '43 and move outwardly said trame, and cause the lowest end of the trame 43, see Figs. 6 und 7, to engage a longitudinally moving pin 52, guided in a side n'o'ection 53 on a verticali movin alate 53, which is supported on the inner side ot' the breast beam. After the detection ot the substantial exhaustion of filling in the active shuttle, and the preliminary movement of a filling carrier, above described, the pattern indicating surfaces 22, and 22 are moved, at aboutI kthe time the Iactive shuttle is being thrown from the magazine to the shifting shuttle boxes, the pattern surface 22, for the' shuttle box shitting` mechanism, to determine whether the-active shuttle is to remain active or another shuttle is .to be sub` stituted for it, and the second pattern surface 22a to determine whether the preliminary moved filling carrier is to be immediately conveyed under the transterrer or is to be held in abeyance.

W'Vhen the active shuttle is to remain active, and the lling carrier which has had the active shuttle has arrived in the shitting shuttle'box end of the lay at about its extreme forward movement, the tollowmg operation takes place. The longitudinally moving pin 52 has a boss 6G tastl thereon, see Fig. 7, carrying a wire 67, through which a vertically moving rod G8 passes. The up per end ot the rod G8 extends through a guide arm 69, and through the movement ot said longitudinally moving pin 52, is adapted to be movedvout of, or into alinement with the end of an arm 70, the hub 70 of which is taston the longitudinally moving shaft 28, and has the outwardlyextending v engaging arm 702l thereonnsee l* 6, which extends above the vertically moving rods 4 8,

and 4S, ot the rocking cradles or supports 49, and 49a. The lower end of the vertically t-ni'tling (n tlitttwttinn ifi' ninte tlnn'n Iutil tutti.
