described. Similarly, in the case of flap pockets, two tools,
as in Fig. 3, may be joined with an adjustable screw for
making the cut of the length required, in one operation.
Figs. 1 and 3 represent tools to be used in a power press, and
are formed with angle blades having cutting-edges at the
end; they also have a width-regulator in the centre, to regu-
late the width of the cut in the fabric, and a shank at the
top to fix them into the socket of a power press. Figs. 2
and 4 represent cuts made in fabric by tools shown in Figs.
1, 3, 5, 6, 7, and 8. The tool as shown in Figs. 5, 6, 7, and 8
is intended to be used in cutting single or small quantities
of pocket-holes; the tool as shown in Figs. 1 and 3 is in-
tended to be used in cutting unlimited numbers of pocket-
holea at one time. The knife or cutter may be made of
any suitable material.

Claim.—The use of an improved appliance, as herein-
before described, for cutting pocket-holes or mouths in cloth
or other fabric, of the width, length, and shape required for
making up.

(white-lead)—a solvent-fluid reservoir and a litharge-
hopper from which measured quantities of their contents are
liberated into a carbonating-chamber, said carbonating-cham-
ber having an agitator therein, and a carbonic acid-gas ad-
mission-hole, in combination with settling-cylinders and a
heated vacuum pan, all as and for the purposes described,
and as illustrated in the drawings. (3.) An improved appa-
ratus for manufacturing lead-carbonate—PbCO₃ or 2PbCO₃+
PbH₂O₂ (white-lead)—consisting of an upper solvent-fluid
reservoir fed by a pump from a lower reservoir and re-
plenished as described, a litharge-hopper, means for regulat-
ing discharges from the upper fluid-reservoir and litharge-
hopper into a carbonating-chamber into which carbonic acid
is admitted and in which is an agitator, settling-cylinders
having floats and siphon pipes leading into a distilling-coil,

No. 12865.—13th August, 1900.—AXEL PETERSEN, of
Hellerup, 7, Copenhagen, Denmark, Commercial Clerk. Im-
provements in locks.

Claims.—(1.) In locks in which the bolt is provided with
a rack gearing into a cog-wheel that may be turned by the
pushing-in or withdrawing of a key, the arrangement that
the lock-cylinder, into which the key is inserted, is made to
turn, and is provided on its side partly with an open slit and
partly with an arm actuated by a spring, which arm, when
the lock is closed, catches into a notch in the spindle of the
gear-wheel whereby such a position is given to the cylinder
that the key gets disengaged from a cog-wheel fixed upon
the spindle and provided with teeth corresponding with those
on a rack on the side of the key. (2.) The cylinder indicated
in claim 1, having a notch s in the lower end of the cylinder
in combination with a spring v in the case so placed that it
catches into the said notch when the cylinder takes up a
suitable position in which its slit is not in line with the cog-
wheel. (3.) The combination with the lock described in
claim 1 of one or several springs w placed in such a manner
that they have a tendency to pull out the lock in order to
render difficult the picking of the lock by the introduction
into the key-hole of a crooked instrument. (4.) In con-
nection with the one or several springs w, indicated in
claim 3, the arrangement on the bolt b of a lug s¹ with a
notch t, in combination with a disc u placed upon the
spindle f so that the disc may fill up the notch t when the
bolt is drawn in, all for the purpose of automatically keeping
the bolt in the drawn-in position. (5.) The spindle f, having
a flattening on the one side of the spindle, in combination
with a spring v on the casing, which spring may rest upon
the flattening and thus prevent the turning of the spindle
when the bolt is drawn in.
