Year: 1875

page_text: LETTERS PATENT to William Morgan-Brown, of the Firm of Brandon
and Morgan-Brown, Engineers and Patent Agents, of 38, South-
ampton Buildings, London, and 13, Rue Gaillon, Paris, for the
Invention of "AN IMPROVED MEANS FOR CLOSING AND OPENING SHUTTELS
AND WINDOWS." -A communication from abroad by Henri Colaert,
of Poperinghe, Belgium, Mechanical Engineer.
caled the 6th July 1875, and dated the 9th January 1875.
PROVISIONAL SPECIFICATION left by the said William Morgan-
Brown at the Office of the Commissioners of Patents, with his
Petition, on the 9th January 1875.
I, WILLIAM MORGAN-BROWN, of the Firm of Brandon and Morgan-
Brown, Engineers and Patent Agents, of 38, Southampton Buildings,
London, and 13, Rue Gaillon, Paris, do hereby declare the nature of
the said Invention for "AN IMPROVED MEANS FOR CLOSING AND OPENING
SHUTTERS AND WINDOWS," to be as follows:-
This Inwanting molator to

page_text: effected from the inside, and rendering impossible all attempts that
might be made from the outside.
In carrying out my Invention I construct the shutters as well as the
windows of sheet iron, and the several parts are so formed as to receive
and protect the necessary mechanism. Each of thesc iron shutters is
composed of a certain number of flaps, generally six, and united
together vertically by hinges in such a manner as to fold one against
the other when they are opened. Along the top part of the framework
of the shutter, and behind the same, is mounted a rod of iron turning
freely at each extremity in appropriate supports. This rod is formed
with a thread, one half of which is a right-hand, and the other a left-
hand thread, and on these threads travel two little blocks attached in
such a manner to each of the central flaps of the shutter that when the
latter is closed they meet together in the centre. On one extremity
of this screw rod is fixed a small bevil wheel which gears into a similar
wheel attached to the top extremity of a horizontal rod disposed in the
framework, and which descending to the bottom of same terminates
with another bevil wheel that gears into a fourth wheel fixed on a
horizontal bar mounted in the interior of the bottom framework of the
shutter. This horizontal bar, which extends only to the centre of the
shutter, carries at its other extremity a similar bevil wheel gearing
in a fifth wheel disposed in the interior of the sill, and which is set in
motion by a pinion armed with a small crank handle. The shaft on
which is mounted the said fifth wheel carries also at about half an inch
from the latter a second wheel of same diameter, and the shaft on
which is fixed the crank wheel is so arranged as to slide at will in order
to bring said crank wheel in gear with the last-mentioned wheel for the
purpose herein-after described.
By means of the mechanism thus described on turning the crank
handle in one direction I cause the shutters to open by folding the
flaps the one on the other, and on turning it in the contrary direction
the shutters unfold and close themselves.
The windows, which are likewise constructed of sheet iron, are so
mounted in their framework as to be capable of being raised or lowered
an inch or thereabout. When they are lowered they are firmly locked
in an iron sill and rest on the extremities of two levers whose other
extremities are united together by means of a pin working in a slot

page_text: formed in both of them, and attached to the surface of a small cog
wheel fixed vertically on the centre of the sill. On this cog wheel being
caused to rotate a quarter of a revolution by means of a smaller wheel
mounted on the above-mentioned crank handle shaft, the pin fixed on
its face depresses the levers, the other extremities of which raise up
the
sash above the sill, and thus allow the window being easily opened.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Morgan-Brown in the Great Seal Patent
Office on the 7th July 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
MORGAN-BROWN, of the Firm of Brandon and Morgan-Brown, Engineers
and Patent Agents, of 38, Southampton Buildings, London, and 13, Rue
Gaillon, Paris, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of January, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said William Morgan-Brown,
Her special license that I, the said William Morgan-Brown, my
executors, administrators, and assigns, or such others as I, the said
William Morgan-Brown, 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 "AN IMPROVED MEANS FOR CLOSING AND OPENING
SHUTTERS AND WINDOWS," a communication to me from abroad by
Henri Colaert, of Poperinghe, Belgian Mechanical Engineer, upon the
condition (amongst others) that I, the said William Morgan-Brown,
my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describė
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 imme-
diately after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said William Morgan-Brown, 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:-
In conjunction with the Drawings hereto annexed and forming part of
this Specification, and in which :-

improved shutters disposed so as to work horizontally.

Figure is a section taken through the top part of the framework
and shewing how the threaded rod and nuts are lodged in the moulding 2
thereof.

Figure 2.
In Figure 9, which is a section through top part of framework, is
represented the manner of disguising the threaded rod L and screw
nuts M in the moulding thereof; O is a flat bar of iron attached to the
screw nuts M, and articulated to the shutters. This bar is made strong
enough to keep the shutters straight from top to bottom.
MECHANISM FOR WORKING THE WINDOWS.
The windows are constructed in such a manner as to permit of their
sashes being raised and lowered about an inch. When lowered they
descend behind a metal plate or shield which effectually guards them
against external violence, as well as against the rain. The way of
opening them is as follows:-After opening the shutters in the manner
above described the handle A is pulled forward about 3 of an inch, and
in such a manner that the pinion B quits the wheel C (thereby throwing
out of work all the mechanism connected with the shutters) and gears
into the wheel P, on the face of which is a pin Q moving freely in the
slotted extremities of two levers R, R, at the other extremities of which
are other pins S attached to uprights T which are guided in their
up-and-down movement by the guide pieces U. At each extremity
of the window sash are fastened wrought-iron pins V, and as the levers
are depressed at one of their extremities by the rotation of the wheel P
they rise at their other extremities until the uprights T coming in
contact with the said pins V force them (and the frame to which they
are attached) to rise sufficiently to clear the metal plate or shield W
to enable the windows to be flung open (see Figure 7), turning on said
pin as a centre. The top frame is furnished with similar kinds of pins X
attached thereto and working in the guide Y, see Figure 9, in which
Figure the window frame is represented as being elevated; when lowered
a hook Z attached to pin X falls in a nook cut in the framework and
helps to keep the window in place:
Having now described and particularly set forth the nature of the
Invention, and the best means I am acquainted with for carrying
the same into practice, I would have it understood that what I
claim is,
Firstly. The folding shutter worked by the mechanism substantially

page_text: And, Secondly. The mechanism for working the windows or sashes,
substantially as described.
In witness whereof, I, the said William Morgan-Brown, have
hereunto set my hand and seal, this Seventh day of July,
in the year of our Lord One thousand eight hundred and seventy-
five.
