PROVISIONAL SPECIFICATION.
An Improved Furnace for Heating Rivets, Drills, Mining Implements,
or other Articles.
I, HUGH BROWN COLLINS, of 121, West George Street, in the County of the
City of Glasgow, North Britain, Merchant, do hereby declare the nature of this
invention to be as follows:-
This invention relates to an improved furnace for heating rivets, drills, mining
implements, or other articles.
The furnace consists of an inclined flue bent round in a zig-zag form and the
heat, which may be supplied by a Lucal or other oil, or gas and coal heater, is
applied at the bottom and directed first downwards and then up the flue. The
rivets are put in at the top of the flue, which is the coolest part and gradually
worked down to the bottom by means of rods, when they come into the hottest
part of the furnace.
The apparatus may also be applied for heating ore.

An Improved Furnace for Heating Rivets, Drills, Mining Implements,
or other Articles.
I, HUGH BROWN COLLINS, of 121, West George Street, in the County of the
City of Glasgow, North Britain, Merchant, do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This invention relates to an improved furnace for heating minerals, ores,
metals, rivets, drills, mining implements, or other articles.
In order that my invention may be properly understood and readily carried
into effect, I have hereunto appended two sheets of drawings, in which Figure 1
represents a longitudinal section taken through the centre of the apparatus, and
Figure 2 is a section on the liner.
The furnace which is constructed of angle iron consists of an inclined flue A
and a return flue A' of zig-zag form and the heat, which may be supplied by
a Lucal as shown or by other oil, spray, vapour, gas or coal heater, is applied
at B and directed first downwards, along the inclined floor of the flue A and

page_text: then up the return flue A and out by the chimney C. The rivets are put in
at the door D at the top of the return flue A', which is the coolest part, when
they lie upon the floor, u, which is formed of fire brick sections b as shown and
are gradually worked down to the bottom partly by gravity and partly by means
of rods, when they come into the hottest part of the furnace and are withdrawn
by sliding aside the hearth or removing the brick from above the aperture or
opening E, or by a door or other suitable opening. For heating drills, holes,
as shown in dotted lines, are put in the sides of the heating flue to allow of
their being entered and the apparatus is readily adaptable for the heating of
different articles as required. The floor and roof of the inclined flues may be
composed of asbestos compound, fire brick, or other suitable refractory, heat
resisting material. H is a hole cut out of the sheet iron frame. The whole
apparatus is mounted upon wheels F in order to render it portable, and a suitable
handle not shown on the drawings, is mounted on the axle G by which it may
be moved about to any convenient position.
The apparatus may also be applied for heating ore or as a liquation furnace,
or for other metallurgical or chemical use, without any material variation from
its present construction.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is-
The improved heating apparatus constructed and operating as and for the
purposes hereinbefore described and shown on the accompanying sheet of drawings,
Dated this 3rd day of March 1900.
