PROVISIONAL SPECIFICATION left by the said Joseph Thomas Harris
at the Office of the Commissioners of Patents, with his Petition, on the
9th March 1865.
I, JOSEPH THOMAS HARRIS, of Marsh Street, Bristol, do hereby declare the
nature of, the said Invention for "IMPROVED IRON DOORS, ESPECIALLY ADAPTED
FOR USE IN ORDINARY BUILDINGS," to be as follows:-
The nature of the said Invention for improved iron doors, especially
adapted for use in ordinary buildings, is as follows;-Apertures to suit the
size and number of panels desired are cut out of flattened sheets of plate iron
of any required thickness, leaving the stiles and rails defined, as in ordinary
framed doors. Each plate thus prepared is rivetted or otherwise secured to
sufficient angle iron of a dimension equal to about half the desired thickness
of the door when completed. Any number of panels as may be arranged in
first cutting through the plate are formed with the pieces then cut out, or
other similar pieces, which are also rivetted or otherwise secured to angle iron
suitable to the required depth of the panels. Cast or wrought mouldings of
any requisite pattern are dropped into the panels. and the whole firmly
attached to the stiles and rails by screws or rivets put through the plate panel
Two entire plates thus
and angle iron into the moulding from the back.

page_text: panelled and prepared are placed together and held in position by two or more
rivetted pins passed through four or more pieces of angle iron attached to the
muntins and rails inside, and then the two complete plates or entire half faces
of doors are thoroughly secured by a continuous band of hoop or other iron
screwed or otherwise attached to the angle iron around the entire outer edge
of the stiles and rails. Hollow stiles, rails, and panels are thus formed to
each door, which may be filled with fire-resisting composition when desired.
The panels need not necessarily be sunk, but may be flush with the face of
stiles and rails. The doors may be fitted with mortice or rim locks, and
furniture, as ordinary wood doors, and may be hung folding or otherwise, or
made to slide. The doors may be hung in wood, iron, slate, or other frames
as desired. These doors may also be made with a cast ground or framework.
SPECIFICATION
in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Thomas Harris in, the Great Seal. Patent Office on
the 8th September 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
THOMAS HARRIS,, of Marsh Street, Bristol, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of March, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Joseph Thomas' Harris, Her special licence that I, the said Joseph
Thomas Harris, my executors, administrators, and assigns, or such others as I,
the said Joseph Thomas Harris, 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 "Iм-
PROVED IRON DOORS, ESPECIALLY ADAPTED FOR USE IN, ORDINARY BUILDINGS," upon
the condition (amongst others) that 1. the said Joseph Thomas Harris, my
executors or administrators, by an instrument in writing under my, 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 per-
formed, 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 Joseph Thomas Harris, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the fol-
lowing statement, reference being had to the Drawings hereunto annexed.
that is to say
Improved Iron Doors, especially
The nature of the said Invention for
adapted for Use in Ordinary Buildings," is as follows: Apertures to suit the
size and number of panels desired are cut out of flattened sheets of plate
iron of any required thickness, leaving the stiles and rails defined, as in
ordinary framed doors. Each plate thus prepared is riveted or otherwise
secured to sufficient angle iron of a dimension equal to about half the desired
thickness of the door when completed. Any number of panels as may be
árranged in first cutting through the plate are formed with the pieces then
cut out, or other similar pieces, which are also riveted or otherwise secured to
angle iron suitable to the required depth of the panels. Cast or wrought
mouldings of any requisite pattern are dropped into the panels, and the
whole firmly attached to the stiles and rails by screws or rivets put through
the plate, panel, and angle iron into the moulding from the back. Two entire
plates thus panelled and prepared are placed together and held in position by
two or more riveted pins passed through four or more pieces of angle iron
attached to the "mumtins" and rails inside, and then the two complete plates
or entire half faces of doors are thoroughly secured by a continuous band of
hoop or other iron screwed or otherwise attached to the angle iron around the
entire outer edge of the stiles and rails. Hollow stiles, rails. and panels are
thus: formed to each door, which may be filled with fire-resisting composition
when desired. The panels need not necessarily he sunk. but may be flush
with the face of the stiles and rails. The doors may be fitted with mortice or
rim locks and furniture, as ordinary wood doors, and may be hung folding or
otherwise, or made to slide. The doors may, be; hung in wood, iron, slate, or
other frames as desired. These doors may also be inade with a cast ground
or framework.
Figures 1 and 2 of the accompanying Drawings are respectively an
elevation and section of a portion of one face of a door constructed according
to my. Invention.
a is a sheet of plate iron having parts removed to make apertures for the
insertion of panels; the parts removed are used for the panels when the cast
or wrought moulding of any requisite pattern is attached thereto by rivets or
screws. a is the part just referred to; b is the cast or wrought moulding;
the rivets or screws by which it is secured pass through a length of angle

page_text: iron c extending round the outer edge of the panel plate. When the two
faces are constructed as above described, a strip of angle iron d is secured to
the inside edge of the same, as shewn in Figure 2. A continuous band e is
then attached by screws to the angle iron d to form the door, the breadth of
the band determines the thickness of the door. Sometimes instead of re-
moving portions as above described, I form the panels and moulding by
pressing the plate in a press furnished with dies, by which a sunken, raised,
or flush moulding and panel are imparted to the plate itself, as represented in
Figures 3 and 4. The doors may be filled with a composition for resisting
the action of fire, if not filled they may be strengthened by placing angle irons
to form stays in any desired position.
In Figure 5 I have shown one mode of preventing the two faces collapsing.
f is a strip of angle iron having the flat surface uppermost secured to the
inside of one face of the door; it is furnished with pins g, which take into
holes formed in a strip of angle iron h secured to the inside of the other face
of the door.
Although I have mentioned in the foregoing description that the doors are
made of sheet iron, I do not confine myself thereto, as they may be made
with a framing of cast iron, and have wrought or cast panels and mouldings
attached to them.
And having now described the nature of my said Invention, and in what
manner the same may be performed, I declare that I claim, the construction
of iron doors, especially adapted for use in ordinary buildings, as herein-before
described and illustrated in the accompanying Drawings.
In witness whereof, I, the said Joseph Thomas Harris, have hereunto
set my hand and seal, this Seventh day of September, Onc thousand
eight hundred and sixty-five.
JOSEPH THOS. HARRIS. (L.S.)
