No. 13713.—13th June, 1901.—WILLIAM ALLEN PENDRY,
of 65, Farnsworth Avenue, Detroit, Michigan, United States
of America, Mechanical Engineer. Improvements in button-
making machines.

Extract from Specification.—My invention relates to an
improved button-making machine having for its object a
machine for this purpose whereby the entire operation of
making completed buttons from suitable blanks may be
carried out by a single machine rapidly and economically,
various operations necessary for the construction of the com-
pleted buttons being carried out by the machine in a succes-
sion of steps or stages from the feeding of the button-blanks
thereto until the finished result is obtained. My invention
has more special reference to a machine for making pearl
buttons, but I would have it understood that I do not
confine its scope or application thereto alone, as it may be
used for the construction of buttons from other materials.
[NOTE.—The number and length of the claims in this case pre-
clude them from being printed, and the foregoing extract from
the descriptive part of the specification is inserted instead.]

strasse, Frankfurt-am-Main, Germany, Manufacturer). An
improved calcium-carbide admission-valve for use with
acetylene-gas generators.

Claim.—In acetylene-gas generators, an admission-valve
for granulated calcium-carbide, consisting of two funnels
arranged within the carbide-receptacle and a valve-block be-
tween the exit-openings of said funnels, operating sub-
stantially as described with reference to the drawing, and
for the purposes specified.

No. 14027.—18th September, 1901.—THURE FREDERICK
NORDENFELT, of Greymouth, New Zealand, Miner. Boring-
pipes for prospecting and other boring purposes.

Claims.—(1.) The double casing or pipes for boring pur-
poses. (2.) The manner in which the different lengths of
inside and outside pipes are joined or fitted together, as
shown at points D E and A.B. (3.) The manner in which
the two casings or inside and outside pipes are screwed or
fastened together.
(Specification, 1s.; drawings, 1s.)

No. 14063.—26th September, 1901.—HARRY TOM SMITH,
of City Sawmills, Christchurch, New Zealand, Engineer,
and ARTHUR JAMES TARRANT, of Tuam Street, Christchurch
aforesaid, Merchant. An automatic electrical apparatus,
for giving an alarm and exhibiting the name of a station
or stopping-place in railway-carriages, tram-cars, or other
vehicles, as each approaches any given station or stopping-
place.

Claims.—(1.) The construction and arrangement of parts
constituting our automatic electrical apparatus for giving an
alarm and exhibiting the name of a station or stopping-place
in railway-carriages, tram-cars, or other vehicles, as each
approaches any given station or stopping-place, and for the
purposes described, and illustrated on the drawings Nos. 1
and 2, and clearly shown by Figs. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
11, and letters A, C, D, E.L., F, F¹, F², G, G.B., H, H¹,
I, J¹, J², J³, K, L, L², M, N, O, P, Q, R, R¹, R², S, T, T², U,
V, V¹, V², W, W², X, Y, Y¹, Z, and E.B. (2.) Employing
an electric bell E.B. worked electrically in parallel and in
conjunction with our automatic electrical apparatus, &c.
(3.) The employment of the following parts in the construc-
tion of our automatic electrical apparatus, &c.—namely, a
balance-weight W, movable pulleys 2 and 3 with cord 5
and the attachments for securing cord and pulleys—viz., 1, 4,
and 11—in combination with drum D, ratchet wheel X,
pawl Z, the peculiar-formed spring Y, the toothed wheel V,
and the spindle T, used for carrying the drum D, ratchet
wheel X, toothed wheel V with pawl Z and spring Y attached
thereto. The whole of the parts particularly described in
this 3rd claim are used to secure the absolute motion of the
escapement-disc C during the forward and backward move-
ments of the escapement-lever E.L., as well as to compel
the remainder of the gearing to move on in the direction
required. The pawl Z is attached to the toothed wheel V,
and firmly pressed in contact with the ratched wheel X by
the peculiar-formed spring Y, thus securing absolute cer-
tainty of motion of the wheel V when motion is imparted to
the escapement apparatus. (4.) The arrangement and com-
bination of the following parts in conjunction with the
electric magnets M, M, forming our escapement apparatus
for regulating the speed and position of the roller R and the
canvas or other belting carrying the laths L. The parts
constituting this claim are as follows: The electric magnets
M, M, the escapement-disc C, which is provided with sixteen
studs on each side of disc (the number of studs may be
varied according to circumstances, and arranged to suit the
number of teeth in the various operating gearing wheels
following). The escapement-lever E.L., with armature N
attached by screws to lugs as shown at O, O, this escape-
ment-lever being secured on spindle Y¹ with suitable set-
screws. The inside portion of this escapement-lever
spanning the escapement-disc C is provided with two
stops P, Q, one on each side, which allows one
stud on disc C to pass alternately as the escapement-
lever and armature are moved forward by the magnets
attracting the armature N, and another stud on the opposite
side of disc C is allowed to pass, when the escapement-lever
E.L. is drawn backwards by the spiral spring S, which spiral
spring is attached to the lever L³ with stud bracket R², also
the stud bracket R¹ for attachment of spiral spring at its
lower end. The spiral spring S, lever L², with stud bracket
R² and the stud bracket R¹, are all portions or parts in the
above claim No. 4 for escapement apparatus, as well as the
bracket H¹, with set-screw for adjusting the travel of escape-
ment-lever, also the spindle Y¹ used for carrying the escape-
ment-lever, and the lever L², which lever L² is used for operat-
ing the spiral spring S. The spindle Y¹ is fixed in position by
two set-screws tapped into framing F, each set-screw being
provided with a milled-headed lock-nut. The set-screws
enable the operator to fix the escapement-lever E.L. truly
in its exact position. (5.) The employment of the com-
bination of parts used in the gearing for transmitting
the motion imparted by the balance-weight, escapement-
lever, and disc, as described, to rotate the four-sided
roller R, which in turn carries the endless canvas or other
suitable belts, upon which belts are secured the laths L,
upon which are painted or printed the names of the
stations, &c., for exhibition through the opening in door
