Application December 22, 1945, Serial No. 636,945
6 Claims. (Cl. 139--255)
This invention relates to improvements in bob
bin receivers for weft replenishing looms and it
is the general object ef the invention to provide
a receiver including a bag which is supported and
reinforced by a frame which holds it in normal
position and by which it may be inverted to empty
the bobbins in it.
It is customary to provide a bobbin collector
for bobbins which are discharged from the shut
tle during the weft replenishing operations. In l0.
an application filed on even date herewith I have
set forth a bobbin receiver having a frame which
supports a bobbin receiving bag the front part of
which is connected to vertical members of the
frame by lacing or the like. It is an important
object of my present invention to construct the
bag in such a way that it will be reinforced by
the frame, more particularly the vertical mem
bers thereof which extend alo-rig the front cor
ners of the bag.

tionof arrow 4, Fig. _3,v
Fig. 5 is an enlarged horizontal section on line

Fig. 6 is an enlarged front elevation looking in
the direction of arrow 6, Fig. 1, and
Fig. 7 is a view similar to Fig. 6 but showing
the modified form of the invention.
Referring particularly to Figs. 1 and 2, I have
shown .a loom frame ID and a lay II supporting
a shuttle box I2 which receives a shuttle S. `Dur
ing replenishing operations of the loom the ex
hausted or _depleted bobbins are discharged
downwardly from the shuttle and are guided for
wardly by a bobbin chute I3 secured to the‘lay
under the box I2. The bo‘bbins are ordinarily dis
charged when the lay is at so-called front center
or in the left `hand position thereof as viewed in
Fig. 1.. `During loom Voperation the chute I3
20 swings back and forth >along a path under the
shuttle box.

Each side member 3i] and 3l is provided near
the lower end thereof with a iitting 35 formed
with a lug or boss 36 for cooperation `with the
associated spring 25. The fittings 35 `may be
vsecured to .their »respective Vside members in any
65 `approved `manner ‘ as `by soldering before the
frame F is bent at its upper end to provide the
arms 33. The lugs or bosses 35 project outwardly
from the vertical center of the frame F and are
preferably in horizontal alignment, as are also
the springs 25.
The bag B is made of cloth and has inner and
outer side walls 31 and 38, respectively, a rear
wall 39, and a front wall 40. These walls extend
l upwardly and provide the bag with an open bob
bin receiving mouth M. Each of the inner and
outer side walls is provided with upwardly ex- .
tending straps or loops 4| through which the
arms 33 extend, as shown in Fig. 1. Each ver
tical front corner of the bag is .provided with an

tion the side members 30 and 3l support the
forward part of the bag.
When the receiver is returned to normal posi
tion the cross bar 32 thereof is placed between
the stops 23 and slippeddown into the recess 22,
after which the receiver is pushedk rearwardly
until the lugs 36 pass under the spring clips 25.
The latter not only prevent upward movement
of the receiver until after the latter has been
moved forwardly of the path of the chute I3,
but also assist gravity in holding the receiver
