IMPROVEMENTS IN DOORS TO LANDAU AND OTHER CARRIAGES SIMILAR THERETO
Year: 1866

page_text: LETTERS PATENT to Philippe Devilliard and Achille Postweiler, Carriage
Builders, of No. 82, Boulevard Sébastopol, Paris, in the Empire of
France, for the Invention of "IMPROVEMENTS IN DOORS TO LANDAU AND
PROVISIONAL SPECIFICATION left by the said Philippe Devilliard and
Achille Postweiler at the Office of the Commissioners of Patents, with
their Petition, on the 18th May 1866.
We, PHILIPPE DEVILLIARD and ACHILLE POSTWEILEB, Carriage Builders, of
No. 82, Boulevard Sébastopol, Paris, in the Empire of France, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN DOORS TO
LANDAU AND OTHER CARRIAGES SIMILAR THERETO," to be as follows:-
The great objection to the present mode of manufacturing the doors of
Landau and other similar carriages is that they cannot be opened without
first lowering the glass, otherwise it would be broken. In order to overcome
this drawback we make the door in appearance similar to an ordinary carriage
door, having the framework complete and independent of that connected to
the hood of the carriage, such part being so arranged simply to admit of the

page_text: door opening and shutting freely. These two parts, that is to say, that fixed
to the hood of the carriage and that forming the frame of the door, are so
connected by hinges as to allow of all the parts moving and folding together
when the hood is thrown back, and this without in any way interfering with
the form of the carriage. When the bood is closed and the door in situ, that
part of the framework connected to the hood at the upper part of the carriage
is secured by a tenon, and that of the door by means of screws, catches, and
other suitable fastenings. The opening and shutting of the hood is precisely
the same as usual, our improvements consisting in the adaptation of a jointed
framework to the door, so as to make it entire and capable of being readily
folded together with the parts connected to the hood in opening the carriage,
and by this mode of construction the necessity of lowering the glass each time
of opening the door is dispensed with.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Philippe Devilliard and Achille Postweiler in the Great
-Seal Patent Office on the 17th November 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wе, PHILIPPE
DEVILLIARD and ACHILLE POSTWEILER, Carriage Builders, of No. 82, Boulevard
Sébastopol, Paris, in the Empire of France, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of May, in the year of our Lord One
thousand eight hundred and sixty-six, in the twenty-ninth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Philippe Devilliard and Achille Postweiler, Her special licence that we, the
said Philippe Devilliard and Achille Postweiler, our executors, administrators,
and assigns, or such others as we, the said Philippe Devilliard and Achille
Postweiler, 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 "IMPROVEMENTS IN DOORS TO LANDAU
AND OTHER CARRIAGES SIMILAR THERETO," upon the condition (amongst others)
that we, the said Philippe Devilliard and Achille Postweiler, 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

page_text: 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 Philippe Devilliard and Achille
Postweiler, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement and accompanying Drawings, that
is to say:
:
The great objection to the present mode of manufacturing the doors of
landaus and other similar carriages is that they cannot be opened without
first lowering the glass, otherwise it would be broken. In order to overcome
this drawback we make the door in appearance similar to an ordinary carriage
door, having the framework complete and independent of that connected to
the hood of the carriage, such part being so arranged simply to admit of the
door opening and shutting freely. These two parts, that is to say, that fixed
to the hood of the carriage and that forming the frame of the door, are so
connected by hinges as to allow of all the parts moving and folding together
when the hood is thrown back, and this without in any way interfering with
the form of the carriage. When the hood is closed and the door in situ that
part of the framework connected to the hood at the upper part of the carriage
is secured by a tenon, and that of the door by means of screws, bolts, catches,
and other suitable fastenings. The opening and shutting of the hood is precisely
the same as usual, our improvements consisting in the adaptation of a jointed.
framework to the door, so as to make it entire and capable of being readily.
folded together with the parts connected with the hood, in opening: the.
carriage; and by this mode of construction the necessity of lowering-the
glass each time of opening the door is dispensed with.
•
The above description will be more readily understood by reference to the
accompanying Drawings, of which Fig. 1 is a front view of our improved
door, having the glass up and the hood closed; Fig. 2 is a-similar-view. of
the same, the hood being thrown back and the glass down. Figs. 8 and 4
represent enlarged views of the bolts and staples. shown on a smaller scale
at C, C, Figs. 1 and 2. This a simple node of securing the framework of
the door to the door when the hood is closed; but the system of bolt and
lock we prefer for this purpose is represented in Figures 5, 6, and 7, and will
be mentioned hereafter.
A, A, are the uprights of the door; B, B, are those of the hood;. C, C,.aro

page_text: the bolts above mentioned. They are furnished with hooks at the upper ends,
which in turning the bolts catch in the rings e, e, attached to the hood frame,
and connect it to that of the door when the carriage is open, that is to say,
having the hood back. D, D, E, E, are the jointed bars usually employed for
opening and closing this species of carriage; F, F, are square hinges placed
at the upper angles of the frame of the door; G, G, is the spring catch for
securing the said frame at the top; H is the tenon serving the same purpose
to the frame J, I, of the hood; J is a pivot hinge attached to the door and
frame of the hood which guides the frame of the door in opening or closing
the hood. Fig. 5 is a modification of the bolts C, C, Figures 1, 2, 3, and 4; it
consists of a copper or other metal plate M, on which the bolt N is mounted;
b, b, are sockets thereto; O is a square thread nut screw, on turning which
the bolt is set in motion by means of the crank piece or arm P. The object
of these bolts is the same as the before mentioned ones, namely, for fixing the
uprights of the door to the door. The part or plate M is attached to the
upright Fig. 9, so that the end of the lock Q is even with that R of the
upright of the door; S, S, is the other part of the lock, which is fixed to the
corresponding frame of the hood; T, T, Figs. 8 and 9, are the parts forming
the cross piece or bar of the top of the door. It will be perceived that the
spring catch G, G, Fig. 1, is dispensed with for a more simple mode of
connection; Fig. 6 is placed at the end u, inside the upright of the door,
Fig. 8, so that the end of the lock V is even with the extremity u; Fig. 7 is
the other part of the lock, which is fixed to the upright of the hood, corre-
sponding with that of the door, Fig. 8.
It will thus bo observed that the principal feature of our Invention is the
adaptation of a jointed framework, readily connected to the door by means of
bolts as described, when the hood is closed, and when open connected to the
frame of the hood. For instance, supposing the landau to be closed and the
door frame connected by the bolt to the door, by giving one single turn to the
nut screw the frame is disconnected from the door and becomes attached to
that of the hood, before throwing back which the glass is lowered. By this
simple arrangement the door can be opened or shut with the glass up, the
only necessity for lowering it being when the hood is thrown back, or, in in
other words, when the carriage is open.
Having thus described our Invention, and the mode of carrying the same
into effect, what we claim and desire to secure by Letters Patent is, the mode
of constructing the framework of the door, as already described and illustrated,
and the means employed for securing the same or affixing it to the door by the

page_text: bolts, as shown Figs. 5, 6, and 7, reserving however to ourselves the right of
varying or modifying the same, which may readily be done without departing
from the principle of action thereof.
In witness whereof, we, the said Philippe Devilliard and Achillo
Postweiler, have bereunto set our hands and seals, this Twelfth day
of November, in the year of our Lord One thousand eight hundred
and sixty-six.
