IMPROVEMENTS IN THE APPARATUS FOR RAISING, LOWERING AND LOCKING THE COVERINGS OR HEADS OF LANDAU CARRIAGES
Year: 1884

page_text: I GEORGE THOMAS CHEETHAM, of 135 Chapel Lane, Bradford, in the County
of York, Coach Builder, do hereby declare the nature of my Invention for
IMPROVEMENTS IN THE APPARATUS FOR RAISING, LOWERING AND LOCKING THE
COVERINGS OR HEADS OF LANDAU CARRIAGES, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :-
.
My Invention has for its object the construction of a simple and effective
apparatus for the raising, lowering, and locking of the coverings of heads of landau
carriages in such a manner, that the head is completely locked when it is raised
and also when lowered; and consists in securing to each standing pillar, a bracket
to which is mounted a coiled spring having a rod attached thereto, which slides in
a notched slotted bracket secured to the pillar and locks the head when either
raised or lowered to the full extent.
In order that my Invention may be better understood, I will describe the same
more in detail, reference being made to the accompanying Drawings, in which
Figure 1 represents a side elevation of such portions of the frame of a landau or
carriage head when closed, as are required to describe my Invention. Figure 2 is
a view of the pillar top with the apparatus attached thereto. Figure 3 a view of
the head when open, and the following Figures are details of the various parts.
Figures 4 and 5 of the notched slotted bracket shewing the position of the lock bar
when the head is respectively closed and open. Figure 6 the lock bar. Figure 7
the coiled spring. Figure 8 the opposite end of rod to which the coiled spring
is secured and Figure 9 a detail of the hinge for securing the cant rail to the
pillar top. In all the Figures where like parts appear they are indicated by similar
letters.
To each standing pillar I secure a bracket A, to which is mounted a coiled
spring B, having the rod C attached thereto, which extends to the notched slotted
bracket D, secured to the pillar top D¹, which is hinged to the standing pillar D² to
which the slat E of the back rib is also hinged.
Each cant rail F is hinged to the respective pillar tops D¹, by hinge G, shewn in
detail by Figure 9, and is provided with a projection G₁, to which the hoop stick H
is secured.

page_text: By arranging the cant rail hinge in this manner, I provide room for the links J
connecting the bar K and lock bar L, the latter of which works in a groove formed
in the back portion of notched slotted bracket D.
When the landau or carriage head is closed, the same is locked by the action of
the coiled spring B pressing the end C¹ of rod C into the bottom notch of bracket D
against the reduced portion of lock bar L at L', thereby locking the head in that
position, and which is unlocked in the following manner:-
In order to lower the head, the cant rail F is raised, which causes the lock bar L
to slide down the groove in bracket D such a distance, that the end of rod C at C¹
is forced out of the bottom notch, and presses against the parallel portion of lock
bar L, the head can then be lowered to the position shewn by Figure 3, and when
in that position, the end C¹ of rod C will be sprung into the top notch of bracket D,
and lock the head by pressing against the reduced portion L².
The head is again raised by moving the cant rail F to the position as shewn
by dotted lines in Figure 3, by which the lock bar L is caused to slide in the
bracket D, and force the end C¹ of rod C out of the top notch, thereby unlocking
the head, which is then free to be raised by the uncoiling of the springs B, acting
through the rods C on the brackets and pillar tops D¹.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what I
claim is :-
The combination of the notched slotted bracket D and lock bar L with the rod C
substantially in the manner and for the purpose as herein before described.
The combination of the notched slotted bracket D with the rod C.
The use of coiled spring B applied substantially in the manner and for the
purpose as herein before described.
