IMPROVED ARRANGEMENTSS FOR OPENING AND SHUTTING CARRIAGE WINDOWS
Year: 1865

page_text: LETTERS PATENT to Sidney Courtauld, of Waddon, in the County of
Surrey, and Charles Wilkins Atkinson, of Saint George's, Bloomsbury, iu
the County of Middlesex, for the Invention of "IMPROVED ARRANGEMENTS
PROVISIONAL SPECIFICATION left by the said Sidney Courtauld and
Charles Wilkins Atkinson at the Office of the Commissioners of Patents,
with their Petition, on the 14th June 1865.
We, SIDNEY COURTAULD, of Waddon, in the County of Surrey, and CHARLES
WILKINS ATKINSON, of Saint George's, Bloomsbury, in the County of Middle-
sex, do hereby declare the nature of the said Invention for "IMPROVED
ARRANGEMENTS FOR OPENING AND SHUTTING CARRIAGE WINDOWS'to be as
follows:-
Our Invention consists in an excentric motion worked by a hand lever
or disc, describing either a whole revolution or only the are of a circle, so
arranged as to be easily accessible, and to be capable of being turned when
it is desired to raise or lower the window to any required distance. The
aforenamed excentric works a lever to which is attached a chain, cord, op
gut, passing round a pulley. Another pulley and cord or gut derives its

page_text: motion from the first-named pulley, and is constructed of such a diameter as
to give the requisite distance of motion to the window. The said cord or
gut is passed round pulleys at or about the top and bottom of the bottom sash,
and is fixed to the bottom of the window frame at or about the centre
thereof, by which means when the excentric is turned by the hand the window
is raised or lowered as required. The weight of the window is counteracted
by a spring or weight, whereby the window can be raised with greater ease.
The force of the spring or weight combined with the mechanical action of the
excentric allows the window to remain at any required height.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Sidney Courtauld and Charles Wilkins Atkinson in the Great
Seal Patent Office on the 14th December 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, SIDNEY
COURTAULD, of Waddon, in the County of Surrey, and CHARLES WILKINS
ATKINSON, of Saint George's, Bloomsbury, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of June, 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 us,
the said Sidney Courtauld and Charles Wilkins Atkinson, Her special licence
that we, the said Sidney Courtauld and Charles Wilkins Atkinson, our
executors, administrators, and assigns, or such others as we, the said Sidney
Courtauld and Charles Wilkins Atkinson, 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 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 "IMPROVED ARRANGEMENTS FOR OPENING AND SHUTTING CARRIAGE WINDOWS,"
upon the condition (amongst others) that we, the said Sidney Courtauld and
Charles Wilkins Atkinson, 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.

page_text: NOW KNOW YE, that we, the said Sidney Courtauld and Charles Wilkins
Atkinson, 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:
Our Invention consists in an excentric motion worked by a hand lever or
'disc, describing either a whole revolution or only the arc of a circle, so
arranged as to be easily accessible, and to be capable of being turned when
it is desired to raise or lower the window to any required distance. The
afore-námed excentric works a lever to which is attached a chain, cord, or
gut passing round a pulley. Another pulley and cord or gut derives its
motion from the first-named pulley, and is constructed of such a diameter as
give the réquisité distance of motion to the window. The said còrd or
gut is passed round pulleys at or about the top and bottom of the bottom
sash, and is fixed to the bottom of the window frame at or about the centre
thereof, by which means when the excentric is turned by the hand the window
is raised or lowered as required. The weight of the window is counteracted
by a spring or weight, whereby the window can be raised with greater ease.
The force of the spring or weight, combined with the mechanical action of
the excentric allows the window to remain at any required height.
Having thus far explained the nature and object of our said Invention, we
will.proceed to describe the same more minutely, and exhibit its practical
working. In order to do this as completely as possible we shall refer to the
Sheet of Drawings accompanying this Specification, and to the letters and
figures of reference marked thereon respectively as follows:-
Fig. 1 is an elevation of the internal mechanism of our improved arrange-
ments for opening and shutting carriage windows, the wooden face and
ornamental carriage stuffing marked S, S, Fig. 2, being removed; Eig. 3
is a section of the mechanism, showing its arrangement within the lower
sash of the door: Like letters denote similar parts throughout all the
Figures.
A is an excentric disc with its strap P actuated by the handle M, which is
moved when desired in the ornamental slot N, Fig. 2; B is a lever having C
for its fulcrum, and attached to the excentric strap by the pin O. The broad
end of the lever B is formed as shown, having a cord D wound round a
small pulley E; this motion actuates the large pulley F with its cord I,
which is passed round it two or three times. The cord I is fixed to the
bottom of the window frame at K, and passes round two small pulleys G, H,
at the bottom and top of the lower sash of the door. The window is here
represented as being shut, the point K being at the top. By moving the

page_text: knob or handle M in the slot to N the excentric is drawn back, and the
lever B takes the position shown by dotted lines, the pulley F revolving
in the direction of the arrow, and drawing down. the window by the cord over
the pulley G. The spring L, which has a tendency to open, being adjusted
to the lever B, as shown, counteracts the weight of the window; this may
also be done by means of a weight or otherwise, and the window will remain
at any required point from being full open to being shut.
.
Having now fully described the nature and object of this our said Invention'
together with the mechanical arrangements which we prefer to adopt, we wish
it to be clearly understood that we do not confine ourselves to the precise
forms, details, or relative dimensions herein-before described or illustrated, as
they may be considerably varied without departing from the principle and
features of our Invention; what we claim as our Invention to be protected by
Her Majesty's Letters Patent is, the mechanical arrangement and combina-
tions of mechanism herein-before set forth and described for opening and
shutting carriage windows.
In witness whereof, we, the said Sidney Courtauld and Charles Wilkins
Atkinson, have hereunto set our hands and seals, this Fourteenth
day of December, in the year of our Lord One thousand eight hundred
and sixty-five
