PROVISIONAL SPECIFICATION.
Improvements in and connected with the Flue Dampers of Portable
and other Ranges.
I, ALEXANDER MATHIESON, of the Firma of Messrs. Mathieson, Wilson, and
Company, of Scotch Foundry Armley, near Leeds, Artistic and General Iron-
founders do hereby declare the nature of this invention to be as follows:-
-
The object of my invention is to provide means whereby the flue dampers of
portable and other ranges can be placed and held at any required position, also to
arrange or construct such dampers that they can be readily removed when required
and to give better access to the flue for cleaning purposes.
In carrying out my invention I employ friction devices consisting of curved pro-
jections or lips upon the flue, the damper handles (which are placed at a suitable
angular position) or the dampers working upon such curved projections or lips, and
in such a manner as to retard the movement of the dampers so that when they are
placed at the required angle or position they are held there by means of the
friction of the handles or dampers upon the curved projection or lips.
The dampers are made so that they are detachable and removable, as is
also the flue cleaning door, so that the flue can be readily cleaned when required.

COMPLETE SPECIFICATION.
Improvements in and connected with the Flue Dampers of Portable
and other Ranges.
I, ALEXANDER MATHIESON, of the Firm of Messrs. Mathieson, Wilson, and
Company, of Scotch Foundry, Armley, near Leeds, Artistic and General Iron-
founders, 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 :-
The object of my invention is to provide means whereby the flue dampers of
portable and other ranges can be placed and held at any required position, also to
arrange or construct such dampers that they can be readily removed when
required, and to give better access to the flue for cleaning purposes.
DESCRIPTION OF DRAWINGS.
Fig. 1, is a front elevation showing my improvements applied.
Fig. 2, is an end elevation partly in section of Fig. 1.
In carrying out my invention I employ friction devices consisting of curved pro-
jections or lips A upon the front plate G of the flue B, the damper handle C
(which are placed at a suitable angular position) working upon such curved
projections or lips, (or the dampers D may work upon such curved projections or
lips which may be arranged inside the front or back of the flue B for this purpose)
and in such a manner as to retard the movement of the dampers so that when
they are placed at the required angle or position they are held there by means of
the friction of the handles or dampers upon the curved projections or lips.
The dampers D are made so that they are detachable and removable, for this
purpose the dampers have pins or projections F working in holes E in the back of
n

page_text: the chimney or flue D and the damper handles C work freely in the front plates G
so that they and the dampers can be lifted out when required. The flue cleaning
door His free to fit into the position shown in the drawings and is held in position
by means of a hook J engaging with an eye K attached to the top of the flue or
chimney. When it is desired to remove the said door all that is necessary is to lift
the said door upwards until the said hook is free to come through the said eye, the
door can then be removed.
Lis the top of the range.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what 1
claim is ;-
;-
1. In portable and other ranges a device whereby the flue dampers can be
placed at and held at any required position, substantially as shown and described.
2. In portable and other ranges a frictional device whereby the flue dampers
can be placed at and held at any required position, substantially as shown and
described.
3. In portable and other ranges constructing the flue dampers so that they
can be removed, in the manner and for the purposes, substantially as shown and
described.
4. In portable and other ranges the combination of flue dampers and flue
cleaning door, as and for the purposes, shown and described.
