is made on the chain, and this tendency also exists when the
chain becomes slack slowly or suddenly. The coupling is
thus secure in the case of a sudden jerk or a sudden slacken-
ing. The hooked pieces forming the coupling are made of
such a shape as to be reversible, so that when worn they
may be interchanged, thus increasing the durability of the
couplings. All points of the couplings are turned inwards,
and all external faces are rounded, so that adjacent objects
will not be caught by it. There are three modifications of
the coupling, which are called by me the “twisted coupling,”
the “block-hook coupling,” and the “tug-hook coupling.”
The invention consists of the features and combination
and arrangement of parts described with reference to the
drawings.

No. 16376.—19th May, 1903.—ALEXANDER PARKER, of
Dannevirke, New Zealand. An improved dust and draught
excluder for doors.*

Extract from Specification.—This invention relates to im-
proved means whereby the crack or opening at the bottom
of a door, when the door is closed, may be covered so as
to prevent the entrance of dust, draught, or rain beneath
the door. The means devised consist of a roller that is freely
mounted in a groove formed in the bottom edge of the door
and which extends throughout the whole width thereof.
This roller is supported by suitable bearings at each end of
the groove, and is provided with a flat plate attached to its
periphery at a tangent, or radially, and extending throughout
its whole length. The edge of this plate is preferably formed
of rubber or other resilient material. When the roller is
partially revolved in its bearings, this plate will be turned
down so that its edge shall engage with the floor. To oper-
ate the roller to drop its plate different devices may be em-
ployed. In the drawings three distinct arrangements are
shown, but I desire it to be understood that I do not confine
myself exclusively to the use of all or any one of such, my
invention consisting principally in the use of a roller and
tangential or radial plate.

Traveller, and CHRISTIAN CASIMIR, of 15, Angus Street,
Sydenham, New Zealand, Tutor. An improved vapour-burn-
ing incandescent lamp.*

[NOTE.—The title in this case has been altered. See list of pro-
visional specifications, Gazette No. 47, of the 11th June, 1903.]

Claims.—(1.) In a vapour-burning lamp, the employment
of a tapered cylinder situated between a vaporiser and a
reservoir for containing the illuminant, said cylinder contain-
ing a granular slag rich in carbon, as specified. (2.) In a
vapour-burning lamp, in combination, a reservoir for con-
taining an illuminant, means for conducting said illuminant
from the reservoir to a tapering cylinder, a vaporising pipe in
connection with the cylinder at one end, its other end being
adapted to deliver the gas formed in the vaporiser into a
semicircular-shaped tube upon whose other end the lamp-
burner is mounted, and carbon in the cylinder, said carbon
being contained in a granulated slag, as described, and for the
purposes set forth.

No. 16661.—18th July, 1903.—JAMES BATES, of Mount
Eden Road, Auckland, New Zealand, Stove-maker. Im-
provements in portable boilers.*

Claims.—(1.) In portable boilers, an outer casing provided
with a boiler or copper supported therein, in combination
with an annular metallic ring secured to the top edge of the
casing and formed with a downwardly and inwardly inclined
top surface and with a bulbed enlargement upon its outer
periphery, substantially as specified. (2.) In portable boilers,
an outer casing provided with a copper or boiler supported
therein, a fireplace beneath the copper or boiler, composed of
a circular plate supported on the outer casing with a de-
pressed central portion and a hole in the depression, and a
grating or fire-bars supported within the depression and cover-
ing the hole therein, such grating or fire-bars being approxi-
mately on a level with the bottom of a door opening in the
outer casing, substantially as specified. (3.) In portable
boilers, an outer casing carrying a copper or boiler, a fire-
place beneath the copper or boiler, a flue leading from the
top of the casing at the rear of the fireplace, a lining of fire-
bricks surrounding the inside of the casing above the fire-
place, and an inwardly projecting piece upon the lining-

bricks at the rear of the fireplace, engaging with the bottom
of the copper or boiler, substantially as and for the purposes
set forth. (4.) The general arrangement, construction, and
combination of parts comprising my improvements in port-
able boilers, as described and explained, as illustrated in the
drawings, and for the several purposes set forth.

No. 16754.—6th August, 1903.—JOHN BENSON, of Grove
Bush, Southland, New Zealand, Labourer. Improved com-
bined collar and hames.

Extract from Specification.—This invention relates to
a combined collar and hames, such being designed in order
to provide for a freer action at the top and bottom, and also
to provide means whereby the traces may be attached more
easily and their pressure on the collar be better regulated
than at present. . . . The combined collar and hames are con-
structed in two halves, as ordinarily constructed, each half
being composed of a front portion A of wood or other suitable
material, and upon the back of which a pad B is secured.
The two halves of the collar are joined together at their
bottom ends by means of a strap C passed through holes
formed in the adjacent edges of the portions A, while their
top ends are adapted to be secured by means of a strap D
(shown in dotted lines in Fig. 1) which passes through
links E secured to the outer faces of the portions A near
their top ends. The traces F are attached to the front
portions A by means of links F¹ that are hooked on to
swivel links G pivoted upon plates H secured to the collar by
means of pins h passing into holes h¹ formed in the collar.
These holes h¹ are made at different heights in the collar, in
order that the plates and swivel links may be raised or
lowered as desired, thus altering and adjusting the pressure
or draw of the traces upon the collar.

No. 16796.—14th August, 1903.—HERBERT DAVIDSON,
Musician, PHEBE JANE CAUSER, Married Woman, and
PETER BRYANT RICHARDS, Machinist, all of Katamatite,
Moira, Victoria. An improved wire-strainer.

Claim.—A wire-strainer consisting of the tube A, in com-
bination with the cross-bar B, forming the apparatus de-
scribed, and illustrated by Figs. 1 and 2 in the sheet of
drawings.

No. 16816.—19th August, 1903.—FOREIGN MCKENNA PRO-
CESS COMPANY, a corporation organized under the laws of the
State of Wisconsin, having its offices at the corner of Mil-
waukee and Mason Streets, Milwaukee, Wisconsin, United
States of America (assignees of David Holliday Lentz, of
Joliet, Will, Illinois, United States of America, Mechanical
Engineer). Improvements in charging-machines for rails or
other material.

Extract from Specification.—Generally speaking, the inven-
tion consists in the provision of a plurality of parallelly
movable transfer tables which are adapted to receive steel
rails, or other bars of iron, and support the same throughout
their length. The steel rails upon the transfer tables are
conveyed by means of said tables over a plurality of preferably
horizontally mounted idlers. When in position over the
idlers the transfer tables are simultaneously lowered, thus
depositing the steel rails upon said idler-rollers, after which
the transfer tables again recede to their former position, the
steel rails remaining upon said idlers. Means are then em-
ployed to charge the rails deposited upon said idlers, over
said idlers, and into a furnace placed at one end of the row
of idlers. The means for propelling the steel rails is then re-
turned to its original position, and a new supply of rails is
again laid upon the idlers by means of said transfer tables.
The second consignment may then also be charged into the
furnace. In this manner a continuous operation of the
charging-machine is effected. The transfer tables and idler-
rollers are preferably movably mounted in one integral struc-
ture, the transfer tables preferably moving transversely to the
roller-bed. The whole structure is mounted upon suitable
wheels, and is adapted to operate upon suitable tracks pro-
vided for said wheels, so that the driving-machine is movable
bodily in front of a row of furnaces into which rails are to be
charged. It is the further object of this invention to facili-
tate the rapid working of the machine, and to automatically
perform operations which had previously to be performed by
hand, whereby a new mode of operation and a new technical
result are obtained. To this end an operating-table is pro-
vided, preferably integrally united with the frame of the
machine, upon which all levers and operating mechanism are
