Year: 1867

page_text: LETTERS PATENT to Edward Thring, of Uppingham, in the County
of Rutland, Clerk, for the Invention of "IMPROVEMENTS IN STOVES OR
FIRE-PLACES."
Sealed the 17th May 1867, and dated the 2nd March 1867.
PROVISIONAL SPECIFICATION left by the said Edward Thring at the
Office of the Commissioners of Patents, with his Petition, on the
2nd March 1867.
I, EDWARD THRING, of Uppingham, in the County of Rutland, Clerk, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
STOVES OR FIRE-PLACES," to be as follows:-
. This Invention has for its object improvements in stoves or fire-places...
For these purposes the fuel to be burnt is placed in a shell or grate, circular
in section and turning on centres; at its two ends an opening is made through
one side of the cireular shell or grate, at which fuel is introduced into it.
When fuel is to be introduced into the shell the shell is turned on its axis so
as to bring this opening to the top, and after putting on fuel the shell is again
turned to bring the opening to the front side, so that the fire therein may be..
the fresh fuel is by this means covered with the heated fuel previously
contained in the shell, and any smoke arising from the fresh fuel will be con-
seen;

page_text: sumed by its having to pass through the heated fuel.
When the shell is
turned to bring the opening towards the front, air is allowed to pass to the
fuel in the shell through perforations or openings formed through its bottom,
and the products of combustion escape from the shell through similar per-
forations or openings and pass away by the chimney, the axes of the rotating
shell may be carried by a moveable frame, so that it may be placed in any
ordinary fire-place, or they may be carried by a frame to be fixed in the fire-
place.
In place of the shell being mounted on axes it may be fixed with the
opening in it towards the front side, it will then form an oven-like chamber
for containing the fuel, by which the amount of fuel required for heating a
room will be considerably diminished. The shell may be of fire-brick, or iron,
or other suitable material,
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Thring in the Great Seal Patent Oflice on the
2nd September 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, J, EDWARD

Thring, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
STOVES OR FIRE-PLACES," upon the condition (amongst others) that I, the
said Edward Thring, my executors or administrators, by an instrument in
writing under my, or their, or one of their hauds and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be filed'
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Edward Thring, do hereby declaro the
nature of the said Invention, and, in what manner the same is to be performed,
to be particularly described and ascertained in and by the following state-
ment thereof, that is to say:-
This Invention has for its object improvements in stoves or fire-places.
For these purposes the fuel to be burnt, is placed in a shell or grate, circular
in section, or it might be of other convenient shape, and turning on centres
at its two ends; an opening is made through one side of the circular shell or
grate at which fuel is introduced into it. When fuel is introduced into the
shell the shell is turned on its axes so as to cause the fresh fuel to be covered
with the heated fuel previously contained in the shell, and any.
smoke arising
from the fresh fuel will be consumed by its having to pass through the heated:
fuel. Air is allowed to pass to the fuel in the shell, through perforations or
openings formed through its bottom, as well as from the front opening, and
the products of combustion.escape from the shell through similar perforations
or openings at the top and pass away by the chimney. The axes of the
rotating, shell may be carried by a moveable frame, so that it may be placed in
any ordinary fire-place, or they may be carried by a frame to be fixed in the
fire-place,
In place of the shell being mounted on axes it may be fixed with the
opening in it towards the front side; it will then form an oven-like chamber
for containing the fuel, by which the amount of fuel required for beating
room will be considerably diminished. The shell may be of fire-brick or iron,
or other suitable material,
a
And in order that my said Invention may be most fully understood and
readily carried into effect I will proceed to describe the Drawings hereunto
annexed,
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front view f a store or fire place constructed according to
my Invention; Figure 2 is a side view of the shell or fire basket, with its
stand or support; Figure 3 is a vertical section; and Figure 4 a back view of
the same.
a, a, is the shell or fire-basket, by preference it is moulded in fire-clay and
burnt in one piece; it may, however, be made in separate pieces, or it may
be in other material in lieu of fire-clay; a', a', are iron bands surrounding
the shell or basket, as is shown on one of them, which is shorter than the rest,
the pivots a, a, are fixed. The stand or support consists of a base 6, which
is shown in plan at Figure 5, at its centre is formed the socket 6', this socket
Gructed according to
my Invention; Figure 2 is a side view of the shell or fire basket, with its
stand or support; Figure 3 is a vertical section; and Figure 4 a back view of
the same.
a, a, is the shell or fire-basket, by preference it is moulded in fire-elay and
burnt in one piece; it may, however, be made in separate pieces, or it may
be in other material in lieu of fire-clay; a¹, a', are iron bands surrounding
the shell or basket, as is shown on one of them, which is shorter than the rest,
the pivots a, a, are fixed. The stand or support consists of a base b, which
is shown in plan at Figure 5, at its centre is formed the socket 6', this socket

page_text: receives an upright spindle fixed upon the other part of the stand or support,
and which consists of a curved bar 6 with notches at its upper ends to receive
the pivots a² of the shell or basket; a³, a³, are perforations in the shell or
basket, which serve alternately for the passage of air to the fuel, and for the
passage away of the products of combustion therefrom.
The fire should be managed in the following manner:-The fire having
been lighted in the shell or basket, which should be inclined about to the
position in which it is shown at Figures 2 and 3, when the fire requires
replenishing the fresh coal is first placed on the top of the bright fire, as it is
shown at Figure 6, then by inserting the end of the poker into a suitable hole
in one of the pivots the shell or basket is turned over in the direction
indicated by the arrow until it is brought to the position indicated at Figure 7
then by moving the shell or basket half round, the vertical spindle turning in
the socket b¹ the fire is brought to the front. The glowing coals will now be
found at the top of the fire and the fresh fuel below.
In witness whereof, I, the said Edward Thring, have hereunto set my
hand and seal, this Twenty-ninth day of August, in the year of our
Lord One thousand eight hundred and sixty-seven.
EDWARD THRING.
