This invention relates to weft replenishing
looms and it is the general object of the inven
tion to provide a spent bobbin receiver removable
from its normal position by a downward motion.
Weft replenishing looms discharge depleted or
spent bobbins downwardly along a bobbin chute
which traverses a given back and forth path as the
lay reciprocates. The bobbin receiving mouth of
the bobbin receiver ordinarily extends under the
forward part of this path so that discharged
bobbins can enter the receiver. The usual bobbin
can which rests on the ?oor must first be pulled
forwardly and then lifted to empty the bobbins in
it. The can is free to be raised without ?rst be
ing moved forwardly, and if this should happen
the bobbin chute might strike the can. ' It is an
important object of my present invention‘ to
mount a bobbin receiver in such manner that it
must be moved downwardly away from the path
of the chute before it can be mnipulate'd for bob
bin emptying purposes.
It is another‘ object of my invention to provide
a support and receiver unit so formed that upward
movement of the unit will establish holding rela
(Cl. 139-255)
The bobbin chute swings along a back and ‘forth
path and bobbins are discharged when the lay is
on front’ center position, or tothe left ‘as viewed
in Fig. 1.
g r
The spent bobbins are collected in a receiver
designated generally at R and including a cloth
bag B and a frame F to which it is attached. The
bag has a mouth 20 which extends rearwardly of
and under the front part of the path of the chute
so that the discharged bobbins can enter the bag.
A support or supporting unit 2| is secured at
22 to the lower part of the loom frame Ill and has
its forward end as viewed from the front of the
loom formed with a head 23 shown in Figs. 3 and
4.. As shown in Fig. 5a vertically extending slot
24 has its inner side nearest the loom formed by a
wall 25;of head 23 and has its outer side partly
closed by front and back ?anges 26 and 21‘, respec
tively, having reference to the front of the loom.
These ?anges are spaced from wall 25 and form
with the latter front and back pockets 28 and 29
respectively. Flanges 26 and 2T, and pockets 28
and 29 are inclined downwardly and away from
. each other, as shown in Fig. 4, so that slot 24 is
tion with the support by a means, such as a spring re in wedge shaped and tapers upwardly.
Front wall 30 of head 23 is provided with a
ment of the unit from the support by a downward
plunger 3! made substantially as shown in
force directed downwardly on‘the unit.
