Morton, of Halifax, in the County of York, Fire-brick, Tile, Retort,
and Sanitary Tube Manufacturers, for the Invention of "IMPROVED
PROVISIONAL SPECIFICATION left by the said George Greenwood,
Thomas Saville, and Joseph Morton, at the Office of the Com-
missioners of Patents, with their Petition, on the 15th February
1873.
We, GEORGE GREENWOOD, THOMAS SAVILLE, and JOSEPH MORTON; of
Halifax, in the County of York, Fire-brick, Tile, Retort, and Sanitary
Tube Manufacturers, do hereby declare the nature of the said Invention
for "IMPROVED MEANS AND ARRANGEMENTS FOR HEATING ROOMS OR BUILDINGS," to
be as follows ..

page_text: articles made of clay or plastic material, and for drying wool or other
fibrous substances or fabrics, wood, or other materials required to be
dried, and consists in the use or employment of the exhaust steam
from the engine, in manner as follows:-Heretofore exhaust steam has
been used for such purposes which has been conveyed by pipes placed
either above or underneath the floor of the drying room, and when under-
neath the floors have usually been made of metal plates. Also in some
cases the metal floor plates have been constructed hollow to allow of
steam being turned into them in a liberated or free state without the use
of pipes, but the steam heretofore used for this purpose has been live
steam obtained direct from the boiler.
Now our improvements consist in using exhaust steam and allowing
the same to pass underneath either or into and in direct contact with the
metal floor plates of the drying room, whereby we greatly economize
fuel and also first costs in the construction of such rooms.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Greenwood, Thomas Saville, and Joseph
Morton in the Great Seal Patent Office on the 15th August 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
GREENWOOD, THOMAS SAVILLE, and JOSEPH MORTON, of Halifax, in the
County of York, Fire-brick, Tile, Retort, and Sanitary Tube Manu-
facturers, send greeting.

cessors, give and grant unto us, the said George Greenwood, Thomas
Saville, and Joseph Morton, Her special licence that we, the said George
Greenwood, Thomas Saville, and Joseph Morton, executors, admini-
strators, and assigns, or such others as we, the said George Greenwood,
Thomas Saville, and Joseph Morton, our 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

page_text: Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVED MEANS AND ARRANGEMENTS FOR
HEATING ROOMS OR BUILDINGS," upon the condition (amongst others) that
we, the said George Greenwood, Thomas Saville, and Joseph Morton,
our executors or administrators, by an instrument in writing under our,
or their, or one of their hands and seals, should particularly 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.
NOW KNOW YE, that we, tho said George Greenwood, Thomas Saville,
and Joseph Morton, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This Invention relates to means and arrangements for heating or
warming rooms for drying bricks, tiles, retorts, sanitary tubes, or other
articles made of clay or other plastic material, and for drying wool or
other fibrous substances or fabrics, wood, or other material required to be
dryed, and consists in the use or employment of the exhaust steam from
the engine, in manner as follows:-Heretofore exhaust steam has been
used for such purposes being conveyed by pipes placed either above
or underneath the floor of the drying roon, and when underneath
the floors have been usually made of metal plates. Also in some cases
the metal floor plates have been constructed hollow to admit of steam
being turned into them in a liberated or free state without the use of
pipes, but the steam heretofore used for such purposes has been "live"
steam obtained direct from the boiler.
Now our improvements consist in using exhaust steam and allowing
the same to pass underneath or into and in direct contact with the metal
floor plates of the drying room, whereby we greatly economize fuel and
also first costs in the construction of such rooms.
Such being the nature and object of this our said Invention in order
that the same may be fully understood we would add, that on the
exhaust steam being discharged to the flues a syphon box or syphon pipe
of ordinary construction will be applied to such flucs for the purpose of
carrying off the water of condensation and preventing the entrance of
cold air.

page_text: Having thus fully described the nature and particulars of this our said
Invention, together with the manner in which the same is to be per-
formed or carried into practical effect, we would have it understood that
we claim as our Invention, the application and use of exhaust steam for
purposes herein described.
In witness. whereof, I, the said George Greenwood, for and on
behalf of myself and the said Thomas Saville and Joseph Morton,
have hereunto set my hand and seal, this Fourteenth day of
August, in the year of our Lord One thousand eight hundred and
seventy-three.
