The parts are so proportioned that the bottom 40 will be slightly above the level of the 5 cross bar [9 when the bag is empty. _ As successive weft replenishing operations of the front end of the plate 40 should remain up on the bar 19 the accumulating weight of the bobbins will tip the back of the ?oor 40 down wardly, causing it to become inclined and eventually slide off the bar l9. Having thus described my invention it will be seen that changes and modi?cations may be made therein by those skilled in the art with the loom occur bobbins will accumulate in the bag and their weight will depress the bottom 40 out departing from the spirit and scope of the against the action of the elastics 42. During this 10 invention and I do not wish to be limited to the accumulation of bobbins the bottom of the bag will descend gradually and will ultimately reach the position indicated in dotted lines in Fig. 1 details herein disclosed, but what I claim is: 1.
