SHUTTLE OPERATING DEVICE
James F. Rourke, Worcester, Mass.
Application June 23, 1936, Serial No. 86,811
6 Claims. (01. 139-133)
.
The principal objects of this invention are to
eliminate the picker stick and the whole picking
motion of a loom for the purpose of eliminating
vibration, noise and wear; to provide submerged
ways for the yarn so that, when the shuttle
moves over the yarn, friction will be materially
reduced; to provide a construction in which the
picker motion produces no sharp bang or other
sudden action, but the action is gentle; to pro?
vide a nipper shuttle adapted to get ?lling from
a stationary supply at either or both ends of the
machine; to provide a tractor shuttle which will
run over a wide space on raceway rods; to pro
vide an ordinary shuttle to be propelled with two
uprights from the shuttle or a nipper shuttle
to be propelled by one upright. at the center of
the shuttle; to provide a construction in which
a magnet is not ordinarily used but can be used
on extreme widths to obtain the momentum of
the shuttle, and to provide a construction which
can be used in connection with my previous Pat
ent No. 1,976,095 with a magnet with cloth 'of
extraordinary width.

Other objects and advantages of the invention
will appear hereinafter.
Reference is to be hadto the accompanying

a preferred embodiment of this invention;

This is an improvement over the type of loom
disclosed in my prior Patent No. 1,976,095, pat
ented October 9, 1934.
‘
'
The invention is shown as applied to a loom
of well known characteristics except that it has
no picker stick and no picker stick motion.
It
has the usual lay sword ID on which is mounted
the lay l8 carrying a three rail track II. A lower
carriage l2 having wheels l3 runs on the track
and is provided with means not shown which
operates the wheels '3 to traverse the carriage
along the track. The means for operating the
50 carriage I 2 does not constitute a part of-this
invention. At the top are two‘ pairs of, prefer
ably rubber tired, wheels l5 which are also
grooved. A’pair of parallel or raceway rods I'l,
preferably cylindrical, constitute a shuttle car
55 rier. The rods I‘! are secured to- the lay l8 by
means of rods 19. It is to be noticed in passing
that these rods H are provided throughout the
portion in which the yarn crosses them with a
series of notches 20. The lower half of the shed
passes through these notches which have in- ’ '
. clined sides.
Therefore, the yarn is located un
der the surface of the rods ll and is not en~
gaged by the wheels 2! of the upper carriage 22
which contains the shuttle. The usual shed 23
is formed. The usual reeds on the lay I8, har 10
nesses 24, and lease rods 25 are used in the ordi~
nary way except that, as stated, the lower yarn
of the shed passes through the cross ways notch
es of'the rods ll, thusreducing or eliminating
the friction between the wheels 2| and the yarn.
This feature is called the submerging of the
warp in the raceway.
, .
.
On the carriage I 2 at each end is mounted a
plate trigger 21 held in a projecting position by
. a spring 28 on a rod 29 which is ?xed to the 1
end of the trigger and guided by a bracket 38.
As the carriage moves along the tracks the end
of the trigger, which is of curved shape, comes
into contact with the stationary cam 26 and the
trigger is pushed in. When the trigger‘ is in its
set position, as shown in Fig. 3, a spring-pressed
vertical rod 3| is held in a bracket 32.
The rod 1
is supported on the top of the trigger plate 21
by the fact that the rod 3| is provided with a
sharp cornered notch 33 which is held in ‘ele
vated position vin a notch 34 in the plate 21. The
pulling in of the plate 21 releases the vertical
rod and the spring thereon forces it down. In
order to set it up it has to be pushed up by a
cam 39 which the bottom of the rod 31 engages 35
at the end of its stroke. This will release the
plate 21 and allow the spring 28 to move it to
such a point that the edge of the hole will hold
it up. The rod 3|, when pushed up, comes
against a ?at surface 35 atone end of the shuttle 40
carriage 22. Consequently the movement of the
carriage l2 will carry with it the shuttle which is
located in the upper carriage 22.
The upper carriage 22 is carried along with it‘
through one of the rods 3| until the carriage l2 14:.5
reaches the shed. At that time the cam 39 cp
erates the plate 21 and releases the upper shuttle
carriage 22. It is carried across the shed by mo
mentum and the lower half of the shed, being
submerged in the notches 20, gives the wheels 50
2| very little friction or resistance of any kind.
The carriage 12 passes through under the shed
until it gets across the loom and the two car
riages go together and ?nally are stopped in
2,136,712
2
a suitable manner not shown and then are start
ed back again in the same way.
It will be observed that in Fig. 3 this upper
carriage or shuttle box is made the same at each
end and one of these rods 3| is located at each
end so as to carry the shuttle box back and forth,
one of the rods being in use in either case.
The shuttle in the carriage 22 gets its ?lling
from a stationary supply at either or both ends
10 of the machine. In the form shown in Figs. 1
and 5 the ordinary shuttle is propelled with two
upwardly extending rods 3|, one moving it in one
direction and the other in the other.
In the form shown in Figs. 6 and '7 this shut
15 tle is propelled by one rod 36 which extends up
wardly in the center into a space 31 between two
springs 38 which project inwardly from the ends
along the bottom of this shuttle. Two cams are
also needed to operate this rod 36 as two cams
20 are needed to operate the two rods 3| in the
other form shown.
'
A magnet can be used on extreme widths of
cloth to maintain momentum after the carriage
i2 is stopped. The main features of this inven
tion can be used in connection with the magnet
operated loom shown in my Patent No. 1,976,095
for excessive widths of cloth. In this case the
carriage l2 can be reciprocated by the means
shown in said patent.
In either form shown, or in any form coming
30
within the scope of this invention, there being no
picker, there is no sudden blow given by it and
the machinery is not used so severely but a gentle
action is provided eliminating vibration and
35
noise.
'
Having thus described my invention and the
advantages thereof, I do not wish to be limited to
the details herein disclosed, otherwise than as set
forth in the claims, but what I claim is:

lower carriage to propel the upper carriage.
2. In a pickerless loom having a lay, the com
50 bination of a track extending across the lay, a
carriage movable along the track, wheels mount
ed on the carriage near the top, two parallel rods
in fixed position guiding the Wheels, an upper
carriage carrying a bobbin, the upper carriage
having wheels movable along said rods, and posi
tive means adapted to move up from the lower
carriage above said rods alternately to propel the
upper carriage.
3. In a pickerless loom having a lay, the com
bination of a track extending across the lay, a 10
carriage movable along the track, two parallel
rods in ?xed position for guiding the top of the
carriage, an upper carriage carrying a bobbin
