page_text: LETTERS PATENT to Charles William Corpe, of Great Winchester
Street Buildings, in the City of London, for the Invention of "IM-
PROVEMENTS IN APPARATUS EMPLOYED IN THE CONSTRUCTION OF CONCRETE
BUILDINGS.""
Sealed the 7th July 1874, and dated the 10th January 1874.
;
PROVISIONAL SPECIFICATION left by the said Charles William Corpe
at the Office of the Commissioners of Patents, with his Petition,
on the 10th January 1874.
I, CHARLES WILLIAM CORPE, of Great Winchester Street Buildings,
in the City of London, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN APPARATUS EMPLOYED IN THE CONSTRUCTION OF
CONCRETE BUILDINGS," to be as follows:-
"This Invention has for its object improvements in apparatus of the
character described in the Provisional Specification of an Invention for
which Letters Patent were applied for by me dated 26th October 1872,
No. 3183, such apparatus being used in the erection of concrete buildings,
and according to my present improvements apparatus of this description
is much reduced in cost, and by its simplicity in working a great saving
in labour is effected.

page_text: Concrete walls are generally constructed between parallel panels of
iron or wood fixed at the necessary distances apart to form the respective
thicknesses of wall, such panels being attached to uprights on either
side of the wall to be constructed. The uprights are held together by
cores adjustable to the various thicknesses of wall required. The
panels are generally attached to the uprights by means of screws or
bolts.
According to my present improvements I attach the horizontal panels
to the uprights by means of a hook and eye. The hook is secured to
the rail of panel by screw bolts passing through the thickness of the
rail, which bolts can be easily removed in the event of the panel being
shortened or lengthened. The eye is forged on and a screw bolt is
passed through the thickness of upright, then secured with a nut at the
back, and with a washer on the front face of upright. By these means
the panels are rapidly fixed in position or raised when required, all
screwing up at each operation being avoided. The eyes on the upright
being 6 inches apart the panelling may be adjusted to any height
required for filling in under joists, string courses, cornices, or other
parts of a building.
In accordance with my improvements I employ another method of
fixing the panels to uprights by means of a slotted plate secured to rails
or panels with screw bolts as before described, and a conical headed pin
on plate screwed on face of upright, the slot in the plate being passed
over the head of the pin and then allowed to drop, thus securing the
panel firmly to the upright.
According to another part of my improvements I use round cores
for panels and uprights with slot holes at certain distances to form
various thicknesses of wall, the parts being secured together by flat pins
or wedges.
SPECIFICATION in pursuance of the conditions of the Letters Patent, a
filed by the said Charles William Corpe in the Great Seal Patent
Office on the 10th July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
WILLIAM CORPE, of Great Winchester Street Buildings, in the City of
London, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of January, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Charles William Corpe, Her special
license that I, the said Charles William Corpe, my executors, adminis-
trators, and assigns, or such others as I, the said Charles William Corpe,
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 APPARATUS EMPLOYED IN THE CONSTRUCTION OF CONCRETE
BUILDINGS," upon the condition (amongst others) that I, the said Charles
William Corpe, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands 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.
NOW KNOW YE, that I, the said Charles William Corpe, do hereby
declare 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 statement thereof, that is to say :-
1
This Invention has for its object improvements in apparatus of the
character described in the Provisional Specification of an Invention for
which Letters Patent were applied for by me, dated 26th October 1872,
No. 3183, such apparatus being used in the erection of concrete buildings,
and according to my present improvements apparatus of this description
is much reduced in cost, and by its simplicity in working a great saving
in labour is effected.
Concrete walls are generally constructed between parallel panels of
iron or wood fixed at the necessary distances apart to form the respective
thicknesses of wall, such panels being attached to uprights on either
side of the wall to be constructed. The uprights are held together by
cores adjustable to the various thicknesses of wall required. The
panels are generally attached to the uprights by means of screws or
bolts.

page_text: According to the first part of my present improvements I attach the
horizontal panels a, as shewn at Figures 1, 2, and 3, Sheet 1 of the Draw-
ings hereunto annexed to the uprights 6 by means of a hook and eye c, c¹².
The hook c is secured to the rail of panel by screw bolts & passing through
the thickness of the rail a, which bolts can be easily removed in the event
of the panel being shortened or lengthened. The eye c¹ is forged on, and a
screw bolt is passed through the thickness of upright, then secured with
a nut at the back and with a washer on the front face of the upright.
By these means the panels are rapidly fixed in position or raised when
required, all screwing up at each operation being avoided. The eyes on
the upright being 6 inches apart the panelling may be adjusted to any
height required for filling in under joists, string courses, cornices, or other
parts of a building.
In accordance with a second part of my improvements I employ
another method of fixing the panels a to uprights 6, as shown at Figures
4, 5, and 6, Sheet 1 of the Drawings, by means of a slotted plate a
secured to rails a of panel with screw bolts d, as before described, and a
conical headed pin 6¹ on plate screwed on face of upright b, the slot in
the plate being passed over the head of the pin and then allowed to drop,
thus securing the panel firmly to the upright.
According to another part of my improvements I use round cores e
for panels and uprights with slot holes e¹ at certain distances to form
various thicknesses of wall, the parts being secured together by flat
pins or wedges, as shown at Figures 7, 8, 9, 10, 11, and 12, Sheet 2 of
the Drawings.
Figure 7 is a general elevation of panel and uprights; Figure 8 is a
plan of the panels with angle when fixed, also shewing the mode of
forming chimney breasts and other projections; Figure 9 shows a panel
plate a¹ connecting the panel a with the upright b. Figure 10 shows a
plan of top or bottom rail of panelling a and section of upright b;
Figure 11 shows a vertical section of panelling showing the manner of
fixing the parts together; Figure 12 shows a separate view of the round
core e with slot holes e¹ to keep the panels to the proper gauge for the
required thickness of the walls.
Having thus described the nature of my Invention and the manner of
comusing the came into nuation what I claim is

page_text: First. The improved method of attaching the horizontal panels a to
the uprights 6 of apparatus employed in the construction of concrete
buildings by means of a hook and eye c, c¹, substantially in the manner
herein-before described and represented in Figures 1, 2, and 3, of the
Drawings hereunto annexed.
b
Secondly. I claim the improved method of fixing the panels a to the
uprights 6 by means of a slotted plate a¹ substantially in the manner
and for the purpose herein-before described and represented in Figures
4, 5, and 6, of the Drawings hereunto annexed.
Thirdly. I claim the use and application of round cores e having slot
holes e¹ for connecting panels and uprights together, substantially in
the manner and for the purpose herein-before described and represented
in Figures 7, 8, 9, 10, 11, and 12, of the Drawings hereunto annexed.
Lastly. I claim the improved construction and arrangement of
apparatus to be employed in the construction of concrete buildings, sub-
stantially as herein-before described and represented in Sheets 1 and 2 of
the Drawings hereunto annexed.
In witness whereof, I, the said Charles William Corpe, have here-
unto set my hand and seal, this Tenth day of July, in the
year of our Lord One thousand eight hundred and seventy-
four.
