being formed when heat causes the mercury contained within
the tube to expand and reach a level above its normal, the
mercury thereby coming in contact with the end of the wire
which is insulated from the metal of the tube, forming a com-
plete circuit for the current of electricity to pass from suitable
batteries connected within the circuit through the mercury,
causing the electric bell or bells to ring. Suitable means
are used for regulating the device so as to cause it to
ring when the surrounding atmosphere reaches any specified
or predetermined degree of temperature.

[NOTE.—The above extract from the specification is inserted in place
of the claims.]

(Specification, 7s. ; drawing, 1s.)

No. 23943.—29th January, 1908.—EDWIN COOMBS, of
Lilydale Grove, Auburn, Victoria, Australia, Plasterer. Im-
provements in and relating to plaster ceilings and like sur-
faces.

Claims.—(1.) The process consisting in fixing meshed
material at a slight distance below joists, placing a mould
sheet or sheets below the meshed material, adding plaster
of thin consistency through the meshed material, and causing
it to flow (unobstructed by said meshed material) on to
substantially the whole surface of the mould sheeting and
form a casting of sufficient thickness, then imbedding meshed
material upon the surface of the casting before it sets, and
subsequently removing the mould sheeting. (2.) The pro-
cess of ceiling-construction by means of cast plaster, using
enriched or embossed moulding-sheeting, wire netting, or
other stiffening-means, scrim or the like between the wire
netting and the mould sheeting, wires or thin rods between
the wire netting and joists, fastening-means for the mould
sheeting, scrim, netting, and wires, and, pressed upon the
plaster casting and imbedded therein, scrim or meshed
material extended beneath the joists. (3.) The combination
of the materials described to form a ceiling or structure
having parts as illustrated in Figs. 1 and 2. (4.) The com-
bination of the materials described to form a ceiling or structure
having parts as illustrated in Fig. 3.

Claims.—(1.) In boots and shoes, in combination with them,
clips formed in at least two pieces, the lower being permanently
secured to the heel-butt, the other sliding under and being
gripped by it, and, passing through the lift, is opened
out, all substantially as shown in the drawing, and
as described and as explained. (2.) In boots and shoes,
in combination with them, a clip formed in two pieces, the
lower one being permanently secured to the ply-sole and grip-
ping the other, which is passed through the sole and opened
out, all substantially as set forth, and as shown on the drawing.
(3.) In combination with removable soles and heels secured
by clips, gripping-studs through which a clip is passed and
doubled over, all substantially as set forth.

No. 24091.—29th February, 1908.—THOMAS MORRIS, Morn-
ington, Dunedin, New Zealand. Protection of steps in
vehicles.

Claims.—(1.) In the steps of vehicles, in combination with
them, a protecting-pad arranged to fit over the face and edges
of the said step, and be secured to same, all substantially as
shown in the drawing, and as described and as explained.
(2.) In combination with a vehicle’s steps, a pad, preferably
having a pattern on the face of same, arranged to fit over
the face and edges of the said step, and capable of being
secured to same, all substantially as set forth.

(Specification, 1s. 6d. ; drawing, 1s.)

No. 24147.—18th March, 1908.—JAMES MULLIGAN, of Christ-
church, New Zealand, Chef (the nominee of George Wesley
White, of Footscray, Victoria, Australia, Farmer). An im-
proved hose-coupling.

Claim.—An improved hose-coupling, comprising a coned
sleeve or thimble placed inside the hose-end, and having its
outer extremity threaded to engage a correspondingly threaded
nut or union adapted to be screwed against the end of a collar,
coned internally and encircling the hose-end, so that said
collar and sleeve move in opposite directions, and thus firmly
grip the hose-end between them, substantially as and for the
purposes set forth.

(Specification, 1s. 9d. ; drawing, 1s.)

No. 24169.—24th March, 1908.—CHARLES WILLIAM CLAY-
TON, of 221 Victoria Avenue, Wanganui, New Zealand. A
spiral-spring-heeled insole.

Claim.—The particular and special use of spiral springs
attached to insoles of boots, shoes, or slippers, resting in
socket-holes bored into the heels of boots, shoes, and slippers,
thus allowing a yielding base for the heels of the wearers of
boots, shoes, or slippers to rest upon, and relieving con-
cussion each step taken, as described.

(Specification, 2s. ; drawing, 1s.)

No. 24174.—25th March, 1908.—JAMES THOMAS HUNTER,
of Queen’s Chambers, Wellington, New Zealand, Patent
Agent (the nominee of the Electric Railway Improvement
Company, a corporation organized and existing under the
laws of Ohio, and having its principal place of business at
Cleveland, Ohio, United States of America, Manufacturers).
Improved method of homogeneously uniting metal bodies by
heat.

Claims.—(1.) A method of homogeneously uniting metals
of unequal heat-conductivities, and having unequal fusing-
points, characterized in that heat from an external source
is concentrated on the metal of greater heat-conductivity
and lower fusing-point, the metal of lesser conductivity
and higher fusing-point being heated largely by con-
duction of heat through the metal of greater conduc-
tivity, whereby the contacting faces of the metals are fused
practically simultaneously. (2.) In the method claimed in
claim 1, heating the metal of greater heat-conductivity and
lower fusing-point by passing a heating electric current
through an electrode of high resistance pressed against the
outer or free face thereof. (3.) In the method claimed in claim 2,
interposing a cementing-material having a lower fusing-point
than the metals to be united, the resistance of the joint
or joints between such metals and cementing-material being
made such that the said material is fused upon the initial
application of the electric current. (4.) The improved method
of uniting a copper bond to a steel rail, substantially as de-
scribed.
