Year: 1875

page_text: LETTERS PATENT to Hilton Coupe, of Preston, in the County of
Lancaster, Smith, and Edward Wilson, of the same Place, Pattern
Maker, for the Invention of " IMPROVEMENTS IN APPARATUS FOR
OPENING AND CLOSING FOLDING DOORS."
Sealed the 7th September 1875, and dated the 24th March 1875.
PROVISIONAL SPECIFICATION left by the said Hilton Coupe and
Edward Wilson at the Office of the Commissioners of Patents,
with their Petition, on the 24th March 1875.
We, HILTON COUPE, of Preston, in the County of Lancaster, Smith,
and EDWARD WILSON, of the same Place, Pattern Maker, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN APPARATUS
FOR OPENING AND CLOSING FOLDING DOORS," to be as follows:-
Our improved apparatus consists of a bracket attached to one part of
the folding door, which bracket is connected by means of a rod with a
regulating screw to a short bracket fixed to the other part of the folding
door; by this means when one part of the folding door is opened the

page_text: other part is also opened in the same direction by the action of the
brackets and connecting rod. The two parts can be kept open either to
the same extent on both sides or to different extents, according to the
angle of the passage into which the doors open.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Hilton Coupe and Edward Wilson in the Great
Seal Patent Office on the 23rd September 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HILTON
COUPE, of Preston, in the County of Lancaster, Smith, and EDWARD
WILSON, of the same Place, Pattern Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of March, in the year
of our Lord One thousand cight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Hilton Coupe and Edward
Wilson, Her special licence, that we, the said Hilton Coupe and
Edward Wilson, our executors, administrators, and assigns, or such
others as we, the said Hilton Coupe and Edward Wilson, our execu-
tors, 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 "IMPROVE-
MENTS IN APPARATUS FOR OPENING AND CLOSING FOLDING DOORS," upon the
condition (amongst others) that we, the said Hilton Coupe and Edward
Wilson, our executors or administrators, by an instrument in writing
under our, or their, or one of our or 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 we, the said Hilton Coupe and Edward
Wilson, do hereby declare the nature of our said Invention, and in

page_text: what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement (that is to say):
Our improved apparatus consists of a bracket attached to one part of
a folding door, which bracket is connected by means of a rod with a
regulating screw to a short bracket fixed to the other part of the folding
door. By this means when one part of the door is opened the other
part is also opened in the same direction by the action of the brackets
and connecting [rod. The two parts can be kept open either to the
same extent on both sides or to different extents according to the angle
of the passage into which the doors open.
And in order that our Invention may be fully understood, and
readily carried into operation, we will proceed to describe the accom-
panying Sheet of Drawings, reference being had to the figures and
letters marked thereon.
Fig. 1 is an elevation of a pair of folding doors to which our improved
apparatus is applied; Fig. 2 is a plan of the same in section. a and b
are the two parts of the folding doors which are hinged as usual to the
door posts, to the part is screwed the bracket c, and to this bracket is
jointed one end of the rod d, the other end of which is provided with a
regulating screw and nut; the part forming the nut is jointed to the
short bracket c which is screwed to the part a. By means of this
apparatus when one part of the folding door is opened the other part is
also opened in the same direction, and when the folding door is open, by
acting on one part both the parts are closed. The two parts can be kept
open either to the same extent on both sides, as shewn by the dotted
lines in Fig. 2, or by varying the position of the brackets c and e, and
the length of the rod d, the doors can be opened to different extents
to correspond with the angle of the passage into which the doors
open.
The apparatus above described is also applicable to folding windows
or French lights.
Having thus stated the nature of our Invention and described a
convenient mode of performing the same, we wish it to be understood
that we do not intend to limit ourselves to the details given, as the same
may be varied or modified, and that we claim the improved apparatus
shewn and described consisting of the brackets cand e and connecting

page_text: simultaneously.
In witness whereof, we, the said Hilton Coupe and Edward
Wilson, have hereto set our hands and seals, this Eighteenth-
day of September, One thousand eight hundred and seventy-
five
