County of Middlesex, Architect, for an Invention of "IMPROVEMENTS IN
SMOKE CONSUMING GRATES OR STOVES."
PROVISIONAL SPECIFICATION left by the said Henry Saxon Snell at the
Office of the Commissioners of Patents on the 11th December 1880.
HENRY SAXON SNELL, of Southampton Buildings, in the County of Middlesex,
Architect. IMPROVEMENTS IN SMOKE CONSUMING GRATES OR STOVES."
"
The Invention has for its object improvements in that class of smoke consuming
grates in which the grate proper is caused to revolve on a pivot at the back
thereof.
The sides of the grate are formed cylindrical to occupy a corresponding socket
or recess formed in the body of the stove, and the covers to the top and bottom of
the grate are hinged, as heretofore, to enable the same to be opened and closed as
required.
According to my present Invention instead of forming the cylindrical sides of
the grate of bars with spaces between them I form them of solid metal so as com-
pletely to enclose the fire at such parts, and thereby prevent the fuel coming against
the sides of the recess or socket, and so interfering with the motion of the grate.
This construction also prevents the waste of the fuel which would be produced
by the unnecessarily speedy combustion at the sides of the revolving grate when
the latter is formed as heretofore.
I also mount the supporting pivot in an iron box or frame, fitted with a number
of friction rollers, bearing against the said pivot to facilitate the rotation of the
grate.
I provide the revolving grate with a spring handle to enable the same to be
readily revolved and adjusted to the required position, a catch being fixed on each
side of the body of the grate to act in combination with such handle.
I also mount on each cover a locking bar pivotted at its centre, and arranged to
take a bearing at its ends when desired under catches formed on or fixed one at
each side of the revolving grate.
In some cases I form the covers to the top and bottom of the revolving grate
solid, so as to reduce the rate of combustion.

arranged to take a bearing at its ends, when desired, under catches d³ formed or
fixed one at each side of the revolving grate d.
In some cases I form the covers d² to the top and bottom of the revolving grate d
solid, so as to reduce the rate of combustion of the fuel in the grate.
Having thus described the nature of my said Invention and the mode in which
I carry the same into effect, I would have it understood that I claim the improve-
ments in smoke consuming grates or stoves, substantially as herein shown and
described.
In witness whereof, I, the said Henry Saxon Snell, have hereunto set my
hand and seal, this Eleventh day of June, in the year of our Lord One
thousand eight hundred and eighty one.
