the Commissioners of Patents, with his Petition, on the 17th February
1868.
I, HENRY TOMLINSON, of Rotherham, in the County of York, Stove Grate
Manufacturer, do hereby declare the nature of the said Invention for "In-
PROVEMENTS IN STOVES OR FIRE-PLACES FOR WARMING APARTMENTS," to be as
follows:-
This Invention relates to certain peculiar constructions and arrangements of
stoves or fire-places for domestic use in warming apartments, whereby economy
of fuel is obtained, and a more ornamental appearance is imparted to the flue
of the stove or fire-place.
According to one modification as applied to an open or closed grate, a lateral
grating or series of bars is made in each side of the fire-holding portion of the
grate, through which gratings a considerable proportion of the products of
combustion pass into a lateral flue partially surrounding a hot air chamber,
formed in each of the cheeks of the stove, that is, one on each side of the
fire. These lateral flues or passages open into horizontal flues at the upper
part of the stove and communicate respectively with two branches of an external
arched flue, provided with dampers, and fitted on to the top plate of the stove,
the crown of the arched flue having a transverse partition made in it to keep
the two lateral flues separate until they both unite in one common flue at the
crown of the arch. A transverse partition is also placed across the mouth of
the main aperture from the body of the fire-place from front to back, such

page_text: partition extending across the middle of the horizontal flues above referred to,
so as to divide such flues transversely. The front and back portion of these
flues are separated by a longitudinal partition, which has the effect of forming
a hot air or smoke chamber in the top front part of the stove. The orifices of
the two branch flues extend partly over the back portion of the horizontal flues
so as to enable the products of combustion passing up through the mouth of
the main aperture immediately over the fire to be carried up the branch flues
with those products which pass off through the lateral gratings and flues.
This external arched flue is susceptible of considerable ornamentation, and is
intended to replace the ordinary brick flue or chimney hitherto used with open
fire-grates. If desired, perforations may be made in the front and back plates
of the stove opening into the lateral hot air chambers above referred to.
According to a second modification the lateral flues are made to open into
the upper part of the stove, and the products of combustion pass off through
two small orifices placed one on each side of a main central flue, each flue or
orifice having a damper or regulating valve fitted therein. In this modifica-
tion the transverse partition does. not extend across the mouth of the main
central exit from the grate, but only across the front portion of the stove, so as
to separate or divide the two lateral flues. The longitudinal partition in the
horizontal flue is also. dispensed with, the entire top part of the stove from
front to back forming a continuation of the lateral flues. In place of the
external arched flue above mentioned, a single external central flue will be
employed.
In some cases it is proposed to form a communication between the lateral
passages or flues and the hot air chambers, in place of having such chambers
entirely closed in.
