page_text: An improved Furnace for the Heating of Tyres.
I WALTER MOTTRAM of Polesworth near Tamworth in the County of Warwick
Wheelwright do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved furnace for the heating of tyres and has for
its object the construction of a simple circular iron furnace, which is so constructed
as to be extremely simple in its working, and to reduce the cost in material for the
heating of tyres.
My said invention consists in an iron furnace made chiefly of tubes which
encompass the fire, first a large one which forms the outside of the furnace, then
a smaller one for the inside. To explain this I give the size of two tubes for a
furnace, the large one will be 5 feet 5 inches in diameter by 12 inches deep with a
2 inch tube, this will have door in so as to admit lifting bars or other means of
removing the tyres when heated. The small tube will be, 3 feet in diameter by
12 inches deep with a 2 inch tube, this is placed inside the large one leaving a
12 inch space between the two, this is the fireplace and where the tyres are heated.
The large tubes are connected and held in position by small tubes which go from
the bottom of the large tube to the side of small tube, thus the outside tube stands
higher than inside one. By these tubes I mean four iron plates secured by rivets
so as to leave a passage between which will carry water, this is to keep the plates
cold when the furnace is in use. I shall cover the said furnace with iron doors,
slides, or the like, the smoke passes over the inner tube to the centre where a flue
or pipe is fixed which is fitted with a movable pipe at the top or is connected on to
any flue or the like which will carry the smoke to any large chimney. All steam
that may be made will escape down this flue or pipe.

An Improved Furnace for the Heating of Tyres.
I WALTER MOTTRAM of Polesworth in the County of Warwick Wheelwright
do hereby declare the nature of my invention for an improved furnace for the
heating of tyres and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to an improved furnace for the heating of tyres and has for
its object the construction of a simple circular iron furnace, which is so constructed
as to be extremely simple in its working and to reduce the cost in material for the
heating of tyres.
In order that my invention may be clearly understood I have appended hereunto

page_text: the accompanying sheet of drawing in which Fig. 1 is a sectional elevation and
Fig. 2 a plan view of the bottom of the improved furnace.
Similar letters of reference are used to indicate like parts in both views.
In carrying my invention into practice I form the circular tube A and inside
this tube 1 place the smaller circular tube B which communicates at the bottom
with the outer tube by the pipes C, the spaces between these pipes being filled up
by the fire bars D. Hinged in a suitable manner on the top of the tube A are the
doors E for covering up the furnace, their inner edges resting upon the supports F
and flush with the trap door G.
'
The furnace is worked as follows-Water is put into the tube A through any
convenient opening fixed on the top, and passes along the pipes C into the small
tube B, and when these pipes are full and the fire ignited the water contained
therein prevents the tubes from getting too hot s that the furnace can be worked
any length of time without injury to the tubes. The steam from these tubes and
the smoke pass down the flue H and thence to any conveniently situated chimney.
The tyres to be heated are placed between the two pipes and the doors closed
down. The ends of the lifting bars are admitted through the side doors J and J¹
when lifting the tyre out of the furnace, or tongues or their equivalent may
be used.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
First. In a furnace for the heating of tyres, the combination of parts whereby
the tyres are heated all round at the same time aud with a small amount of fuel
substantially as herein described and shown.
. Second. In a furnace for the heating of tyres, the combination of parts whereby
an amount of water flows round those parts which are brought into contact with the
fire, substantially as herein described with reference to the drawing.
Dated this 7th day of April 1896.
