The bar24 of the frame 20 is capable òf sliding and turning movements in the bearing From the foregoing it will be seen that I have provided a simple mounting for a spent bobbin Areceiver of a weft replenishing loom, the re ceiver being rotatable about an axis which as shown herein-r is horizontal and substantially parallelA to the length -of the .lay as seen in Fig. 2 so that the mouth of the receiver can be swung 32, hence the support 3d provides a sliding and j JU to a forward inverted position to facilitate pivotal mounting for the receiver.v 4_emptying of- the> bobbins.
