combinations and arrangements of parts com
prising the same, will be understood from the
hereinafter contained detail description when
considered in connection with the accompanying
25 drawing, forming part hereof and illustrating
one embodiment of the invention.

While a speci?c embodiment of the invention
is illustrated in the drawing, it will of course be
understood that minor changes and modi?cations
may be made in the particular construction,
shown, and the invention may be embodied in
50 other forms as will appeal to those skilled in the
art and falling within the scope of the appended
claims, without departing from the spirit of the
invention.
Referring to a detail description of the par
55 ticular embodiment of the invention illustrated
wood or similar material with a metal sleeve 8
secured thereon forming the outer contact base
portion.
The metal sleeve, as shown, projects
a short distance beyond the inner end of the
main body part 7 and is provided with an out
wardly projecting ?ange 8’ for engagement by
?ngers 9, ID to- removably hold the ?lling holder
on the spindle. On the rear portion of the spin
dle is a coiled metal spring I I and a metal washer
l2, the spring being interposed between an en
larged part of the spindle and the washer and
acting to ‘press the washer against the ?ange 8’
of the metal sleeve 8, and the latter against the
retaining ?ngers 9——|0.
Set in the bottom of the shuttle is a transverse
pin [3, said pin being positioned to extend below
the metal sleeve 8 of the cop or bobbin when the
bobbin is placed on the spindle. Pivotally mount
ed on the pin I3 is a feeler member M in the
form of a small metal ?nger having an enlarged
base portion l5 through which the pin [3 extends,
and having a beveled face It at its outer end
adapted to contact with the metal sleeve 8 when
the bobbin is almost emptied of its ?llings. The
forward end of the feeler member I 4 is pressed
toward the metal sleeve 8 of the cop or bobbin
by an elastic rubber strip I‘! attached at opposite
ends to opposite sides of the shuttle and engag
ing the under side of the feeler member.
The rubber strip I1 may conveniently be
formed from an ordinary rubber band as shown,
the band being severed and formed with knots l8
at its ends, and the end portions of the rubber
strip being engaged with notches IS in the re
taining ?ngers 9-H) with the knots I8 disposed
at the rear side of the ?ngers 9-40. The metal
base portion l5 of the feeler member in rear of 50
the pin I3 is provided with a notched portion 20.
A transverse pin 2! on the shuttle extends be
tween the sides of the notched portion 20, said
pin cooperating with the notched portion to limit
the pivotal movement of the feeler member to 55
2,127,182
2
prevent the same from moving upwardly too far
when the shuttle is opened to change cops, and
also to prevent the feeler member from falling
through the opening in the bottom of the shut
tle should the rubber strip break.
Secured to one side of the shuttle by small bolts
and nuts 22—23 is a contact plate 24 of brass
or other suitable conducting material, said con
tact plate being so positioned that when the
shuttle is in the box the plate will be in contact
with the iron swell or front part 2 of the box.
The contact plate 24 is electrically connected to
the feeler member l4 through a short conductor
wire 25 having one end secured to the bolt 22
15 and connected at its other end to the pivot pin
13 of the feeler member. Within a recess of the
shuttle at the rear end of the spindle is a coiled
spring 26 and a plate 21, the spring pressing the
plate against the rear end of the spindle.
The other end of the spring 26 bears against
20
the head of a contact screw 28, the end of which
is in contact with the end of an inwardly ex—
tending stem 29 on the steel shuttle point 36,
which latter when the shuttle enters the box,
makes contact with a contact on the picker. As
25
will be understood, the spring 26 and plate 21 act
to hold the spindle in operative position, and
also serve as an electrical connection between
the spindle and contact screw 28.
Referring particularly to Figures 1, 5 and 6 of
the drawing, the picker shown comprises a cylin
drical shaped head part 3|, an intermediate por
tion 32, and an enlarged end portion 33, the
latter being tubular to slidably engage the guide
34. 35 designates the picker stick of con
35 red
ventional form having its upper end extending
through a slot in the picker. The picker is
formed of any suitable nonconducting material
and is provided at each side of its head with a
contact 36, with which the shuttle point 30 is
adapted to contact. On the enlarged tubular end
portion 33 of the picker are a pair of binding
posts 31. A pair of conductor wires 38—-39 con
nect each one of the contacts 36 with one of the
45
binding posts 31 and the pair of conducting wires
38-—39 are shown connected intermediate their
ends by a conductor wire 46. In the particular
exempli?cation of the invention illustrated in the
drawing, the picker is formed of layers of raw
hide secured together by rivets 40’, as shown,
50 with the contacts 36 of the head and the con
ductor wires 38-——39 and 4!) embedded therein,
the contacts 36 being in the form of soft copper
cores, and the conductor wires 38-39 and 46
being arranged between the layers of rawhide out
55
of contact with the rivets 46’.
On the upper part of the picker stick near the
picker is a binding post 4|, and 42 is a conductor
wire connected with the binding post 41 on the
picker stick and one of the binding posts 31 on
60 the picker. The conductor 42 is ?exible to allow
for relative movement between the picker and
stick, the same preferably, as shown, taking the
form of a coiled wire or spring.
43 designates a
for operating a conventional knock-off device for .
stopping the loom when the circuit is closed.
To prevent the ?lling from running out com
pletely from the bobbin before the closing of the
circuit, a small extra bunch of ?lling material is
wound on the rear end of the cop or bobbin in
accordance with the regular practice in the use
of ?lling feeler mechanisms. In operation, as
will be understood, when there is ?lling on the
cop or bobbin, the ?lling separates the feeler 4 O
member 14 from the metal contact sleeve 8 so
that the circuit is broken at this point, but as
soon as the cop is almost emptied of its ?lling,
the end I6 of the feeler member I4 will contact '
with the metal sleeve 8 so that when the shuttle
is boxed, the circuit will be closed through the
binding post 45, the loom frame, the iron swell 2
of the shuttle box, contact plate 24, feeler M, the
metal sleeve 6, washer l2, spindle 4, spring 26,
plate 27, contact screw 28, stem 29, shuttle point
30, and one of the contacts 36 on the picker.
As will be understood, with the picker head
provided with a contact 36 at each side thereof,
the picker is reversible or adapted to be con
nected with the picker stick at either side of the
25.1
loom.
It will be noted that by the particular con
struction and arrangement of parts hereinbefore
described, ?lling feeler mechanism of a simple,
ei'?cient nature is afforded that can be readily
applied to fancy pick and pick looms. With
looms that have change boxes at both sides, the
mechanism can be installed at either side, and
it will be observed that it obviates the necessity
for built in contacts on the iron swell or box
35.2:
front 2, which are objectionable because they
make it dif?cult to bend and shape the iron swell.
