This invention relates to improvements in weft '
replenishing looms and .it'is the general object of
the invention to provide a receiver for discharged
bobbins so constructed that it can be readily

plished by the same mechanism which effects in

able to move rearwardly under the path of the

.
It .is an important objectof my present inven
tion to provide a bobbin receiver having a rigid
frame from which a cloth bag is suspended, and
mount the frame in such manner that it can be 20
This feature of the invention is possible dueto
the fact that one of thesuspending links for the
‘floating lever moves ?rst forwardly away from its
‘moved forwardly and upwardly by swinging move
version of the mouth.
With these and other objects in view which
will appear as the description proceeds, my in
vention resides in the combination and arrange
ment which inverts the mouth to facilitate dis
charge of bobbins from the receiver into a box,
carriage or the like which is moved from loom

The aforesaid chute traverses a given path
during the back and forth reciprocation of the
lay and the mouth of the receiver extends rear

more particularly in Figs. 2 and 3 the frame may
be made of a single piece of rod material and
mouth is inverted and opens downwardly so that
as the bobbins are discharged upon raising the
bag they will fall into a box or the like 42 which
is moved from loom to loom. During the latter
has a front member i5 which is bent rearwardly
part of this motion the link 25 which has been
to de?ne an outer side member I8, after which ‘
the frame is bent to the left to form back mem
ber I1 extending in a direction substantially par
allel to the member IS. The free end of the
frame is then bent forwardly to form an inner
side member l8 which terminates close to the
front member l5. These four members de?ne
an opening or mouth M through which the de
scending bobbins pass into the bag. Any convene
ient means may be provided for attaching the
bag to the frame and the latter will ordinarily
be inclined downwardly and rearwardly as shown
in Fig. 1 to provide an upwardly opening mouth.
The mechanism for' controlling the movement
of the frame F comprises a floating lever 20 the
. upper end of which is provided with a hub 21 in
which the forward member l5 of the frame F
is held in ?xed position by a set screw 22. I do
not wish to be limited to this particular means
for fastening the frame to the ?oating lever,
but it is desirable that the frame and lever be
moving forwardly, returns to rear position
against stop screw 31 and the frame is stable
when in the position of Fig. 7. A tab or the like
43 may be secured to the bottom of the bag to
facilitate lifting it to the position shown in Fig. '7.
After the bag has been emptied the attendant
will let it fall behind the frame F, and will then
push the frame backwardly, reversing the pre
vious operation. During this reverse movement
the links and ?oating lever cause the frame to
traverse a determined or ?xed path in which the
mouth M will assume a position below the path of
the chute before reaching the ?nal reset position
under the path, such as shown in Fig. 1. In this
way all danger of interference on the part of the
reciprocating chute is eliminated.
During movement of the receiver toward and
from discharging positions the pivots 26 and 29
swing around primary and secondary arcs a and
I), see Fig. 1. Successive positions of the pivots
26 and 29 along their arcs cause the turning of
