SIDNEY CHARLES LEEDHAM FULLER, of Bath, in the County of Somerset,
"IMPROVEMENTS IN THE ARRANGEMENT OF MECHANISM FOR FACILITATING
REGULATING THE RAISING AND LOWERING OF THE HEADS OF LANDAUS AND
OTHER CARRIAGES,"
AND
This invention consists in improvements in the arrangement of mechanism for
facilitating and regulating the raising and lowering of the heads of landaus and
other carriages.
In landaus and other carriages of ordinary construction a spring is arranged to
assist the raising of the head by tending to push the same up into position, and
this invention relates to the arrangement of a spring in such a manner that it
assists in raising the head of the carriage by acting thereon with a pulling force
by means of a lever connection whereby the strain is made almost entirely tensile
thus giving greater power with an equal sized spring thereby permitting the
employment of lighter springs and reducing the strain on the pillar hinge.
The nature of this invention will be clearly understood by reference to the
accompanying Drawings in which Figure 1. is a side elevation of a spring and
mechanism connected therewith arranged for facilitating the raising and lowering
of the front portion of the head of a carriage, Figure 2, being a cross section of the
same. Figure 3. shows a spring and mechanism connected therewith arranged in
accordance with this invention for raising the back part of the head or hood of a
landau or other similarly headed carriage. Figure 4, is a detached view of the
rod E. E'. E, and Figure 5. is a section of the last mentioned rod taken through
the line A. B. Figure 4. The same letters of reference indicate like parts in all
the Figures. A, is a coiled spring which is arranged on the rod B. the ends of
which are shown respectively at B'. B¹¹. The end B. of the rod B, is pivoted or
hinged to the lever C, which is fixed on the spindle C, connected to the pillar
framework F, of the head of the carriage. The end B¹. of the rod B. is arranged to
work through the swivel D, which is attached to the frame of the carriage. The
rod B. is also arranged to pass through the eyes or apertures formed in the
extremities E. and E. of the rod E. The ends of the spring A. bear respectively
against the end E", of the rod E, and the screw nut H, on the rod B.

page_text: Instead of employing the swivel D, any part of the rod E, is, in some cases,
attached on pivot to the frame of the carriage, or any extension of the rod E, is so
used thus allowing for the rise and fall of the end B, of the rod B, when the
lever C, is moved, or, the rod E, is affixed to the body of the carriage by two
moveable parallel connecting rods which may be pivoted or the swivel D, is
retained and that portion of the rod E, marked E, is fixed on a pivot to the body,
but in this latter case the distance between the point E. and the pivoted part
fixed to the body frame work must be of sufficient length to allow of the up and
down travel of the lever or the rod E, is, in some cases, fixed to the framework of
the body with a slot to allow of the up and down travel of the rod B. when the
lever C, is moved or the lever E, is, in some cases, fixed and the rod B. is
connected with a slot in the lever C¹.
In Figure 3. of the accompanying drawings the rod B. is shown in a position
which is nearly horizontal but, when considered desirable, it is arranged at the
side of the pillar F. or at any other suitable angle to the same.
