BOBBIN CLEARER FOR- FILLING REPLENISI-IING LOOMS.

Application filed January 22, 1927. Serial No. 162,865.

This invention relates to improvements in means for removing from a shuttle discharged from automatic filling-replenishing looms the trailing end of the filling so that the bobbin will be entirely cleared or cleaned of filling during its passage into the bobbin receiving box and the general object of the present invention is to provide very simple means for this purpose which includes means whereby the bobbin may be positively guided downward past a revolving spindle which will engage the filling drawn from the abandoned bobbin, unwind the filling from the bobbin, and leave the bobbin clear so that it does not have to be cleaned by hand afterwards, this device further doing away with any chance of the free end of the yarn being caught by the moving shuttle and carried through the shed and woven into the cloth, which would render the cloth imperfect.

My invention is illustrated in the accompanying drawings wherein Figure 1 is a fragmentary elevation of a loom having my improvement applied thereto, part of the lay beam and my attachment being broken away;

Fig. 2 is a section on the line 2 -2 of Figure 1;

Fig. 3 is a section on the line 3-3 of Figure 1; 7

Figures 4 and 5 are perspective views of the front and rear chute plates respectively;

Fig. 6 is an elevation showing the manner in which the spindle is driven.

Referring to these drawings it will be seen that I have illustrateda portion of the lay beam 10 of a loom and a portion of the magazine 11 disposed above the lay beam and from which filled bobbins are discharged automatically into a shuttle. After the filling on a bobbin in a shuttle has become nearly used up, the used up bobbin is automatically discharged from the shuttle by means which forms no part of my invention but which is well known in the art, and the more or less empty bobbin is discharged through a slot 12 which is formed in the lay beam and in a plate 13 constituting the face plate of the lay beam. A box 14 receives the shuttle so discharged and a shield 15'is ordinarily supported by the lay beam just rearward of the slot- 12 to act as a guide for the bobbin to cause its discharge into the box.

My invention consists in providing in connection with the shield 15 a chute element 16 which may be made of metal, leather, cloth,

wood or any othersuitable material This is attached as illustrated, to the under face of the lay or may be attached to the shield itself. Preferably this part 16 has inwardly extended ends 17 which extend around the side edges of the shield 15 so as to partially embrace the same and together with the shield constitute a chute through which the bobbin is discharged. One wall of the chute thus formed is provided adjacent its lower edge with a strip of card clothing designated 18 or material of like nature which will act to catch the free end of the yarn or filling on the bobbin as the bobbin falls through the slot.

Disposed above the box 14 and mounted upon a bracketlQ is a spindle 20, this spindle being driven in any suitable manner but illustrated as driven by mounting thereon a pulley 21 driven by a belt 22 from a driving pulley 23. The pulley 23 is preferably of wood and about 4 in diameter while the pulley 21 is preferably of iron and about 1% in diameter. The pulley 23 is mounted upon the crankshaft 24 of the loom and the bracket 19 is slotted so as to permit a proper adjustment of the spindle. The spindle is disposed as shown in Figure 1 so as to extend across the open mouth of the box 14 and, therefore, extend across the path of movement of the discharged bobbin.

In the operation of this device, when the bobbin is discharged it falls through the slot 12 and downward through the chute formed by the parts 15 and 16. The floating end of the filling on the bobbin is likely to be caught by the card clothing 18'so that as the bobbin moves downward past the spindle the filling will be brought against the spindle and the spindle will wind up the filling. The filling may be so short as to leave the bobbin before the bobbin has reached the box but, on the other hand, the bobbin may drop into the box but the spindle will continue to wind the yarn off the bobbin until the bobbin is entirely cleared.

I claim 1. In a weft replenishing loom having a slotted lay beam through which discharged bobbins pass and a receiving box disposed below the lay beam, of a chute mounted below the lay beam, the chute being rela tively shallow from front to rear and having a length slightly greater than the length of the bobbin and comprising front and rear walls and end walls, means disposed within the chute for detaining one end of the filling on the bobbin, and a spindle rotatably mounted between the lay bean] and the box in the path of movement of the bobbin and adapted to engage the filling and wind it oil from the bobbin.

2. The combination with a replenishing 100111 and a receivingbox, the 100111 including a slotted laybeani, ot' a chute mounted upon the under side of the laybeani and oscillating therewith and receiving a discharged bobbin through said slot, said chute including a back wall attached to the laybeam and having downwardly convergent side edges, a front wall, end walls extending rearward from the front wall and then signature.
