Al the working parts are light and wood iostead OF
metal is used for nntcDg-rodi, shutle-binders,
shuttes gavels and others. Tne driving belt is round
and ihe driving pulley is cut with three grooves OF
different diameter, thus enabling the girls who are
paid by the pi. ce TO run the mschine faster slower
according TO their ability. This arrangement i, good
in moral sense since by exciting emulation and pc.
cunisry interest it tends 10 make the operatives more
ski1ful. This pulley turns freely ON the shaft,
ard is always in motion when the power OF
the factory is. To connect the puly with the
loom, there are inside Of IT,, and on the shaft,
three friction segments of circle covered with leather,
which, by kind OF togge joint, are strongly pressed
agar st the pulley Outside of them, which they carry
rOui by friction. This device is extremely ing9n-
ious much superior TO the usual process of fast and
free pul4y-in ths, that it allows of stopping tae
loom more rapidly arer the breaking of the thread,
and it will prove useful in many machines beside
looms The device for making the loom stop BY Itself
when the filing breaks, is in priucipe tue ordinary
one but here for the wires which rest against the
thread when not broken ard lfG the small hook
which stops the motion when not lifted, are substi
tuted small wooden sticks. These are often broken
by the shuttle, and others are as easily substituted
which is not the case when made of iron of the same
piece with the hook. If the filing breaks the hook
mentioned catches lever, which, acting on several

against the center OF the leg This is better than acting
agarst one end as is usual; but it would be better

higher which sldes against the arc of circle, the

mere secure that the harness is pulled straight. The
shuttle bDders which stop the shuttle the end of
its course by eide friction are in ordinary looms acted
upon by stationary springs. so tina. the same amount
of friction which is necessary to stop the shuttle has to
be overcome for throwing it, In this machine a
whole spring is acted upon by pins on tde connecting
rods that transmit the motion from the shaft to the
leg, in such that the bincer begins to a,t the

similar, but not perfect, exsts in w. Masons loom
but its parts being of metal, are more heavy. Wlat
makes the looms Of the Empire Works more worthy
of cOmmendation fIom us is wooden guard, which
confines the shuttle between the head the legsoe and
the reel without any possibility of escape. Such a
guard, made of iron wire, exists in some looms, but it
ought to be in all, broken thread in the way is
apt to entange it, and the slightest obstruction sends
the shuttle flying in the face or breast of the attending
girl, with sufficient force TO knock out an eye or do
even more serious injury.

The tool lie forged with two horns each ground for
cutting One acts during the forward stroke the other
during the return stroke. One s shaped for cutting,
the other for smoothing. The tooholder is arranged
20 as to turn the tool incline it in any direction, so
that both cutting edges can be placed in the proper
relaive position without extra labor in fitting them.
This machine is muca simple than those known
for the same purpose in which the toolholder s made
to revolve half circumference at each end of the
stroke, so as to bring the cutting edge against the
work.
