DREVIFICATION.
I, JAMES ALFRED LAMPLUGH of the Firm of Lamplugh and Brown of
No 135 Great Colmore Street Birmingham in the County of. Warwick, Saddler
do hereby declare the nature of the said invention for "AN IMPROVEMENT
IN SADDLES FOR BICYCLES, TRICYCLES AND SUCH LIKE VEHICLES to be as
follows:-
:-
"
My invention relates to a construction of saddle for bicycles, tricycles and such
like vehicles, the object which I have in view being to provide an elastic seat for
the rider free from all jar. For this purpose I provide a steel plate of a form
approximately the sector of a circle, corrugated longitudinally to give it stiffness.
To the narrow end of this plate is secured the front part of the leather of the
saddle, preferably with a layer of caoutchouc or other elastic material interposed
between the leather and the steel. The other or back end of the plate, which is
approximately an arc of a circle or which may be straight is bent into a trough
form and in this trough is cemented or otherwise secured a round band of
caoutchouc or other elastic material. The broad end of the leather of the saddle is
passed partly over this elastic band and secured to a steel strip underneath it.
This steel strip is connected by several helical springs to studs projecting down
from the main steel plate, each spring being provided with an adjusting screw
and nut so as to give such elastic strain as may be desired. The steel plate is
curved in such form that throughout its length there is a free space between it and
the leather above.

page_text: I, JAMES ALFRED LAMPLUGH of the firm of Lamplugh and Brown of
N° 135 Great Colmore Street, Birmingham, in the county of Warwick, Saddler,
do hereby declare the nature of my invention for "AN IMPROVEMENT IN
SADDLES FOR BICYCLES, TRICYCLES AND SUCH LIKE VEHICLES "and in what
manner the same is to be performed to be 'particularly described and ascertained
in and by the following statement:-
My invention relates to a construction of saddle for bicycles, tricycles and such
like vehicles, the object which I have in view being to provide an elastic seat for
the rider free from all jar. For this purpose, I construct the saddle as I will
describe referring to the accompanying drawings. Fig. 1 is a plan of the saddlo
looking from below and fig. 2 is a like plan of the same with a modification to
which I will presently refer; fig. 3 is a longitudinal section, taken along the
line X X in fig. 2, and fig. 4 is a transverse section on the line Y Y of fig. 3. In
these figures corresponding parts are marked by similar letters. A is a steel plate
of a form approximately the sector of a circle corrugated longitudinally to give it
stiffness. To the narrow end of this plate is secured the front end of the leather B
of the saddle preferably with a layer C of caoutchouc or other elastic material
interposed between the leather and metal. The back end of the plate A is bent
into a trough form into which is cemented or otherwise secured a round band D of
caoutchouc or other elastic material. The broad end of the leather B is passed
partly over the elastic band B and secured to steel strips E. These strips E are
connected by several helical springs F as shewn in fig. 1 or simply by bolts G as
shewn in figs. 2 and 3 to screwed studs H which project down from the plate A
and which serve to hold by nuts the clamp bar J by which the saddle is secured to
the spring of the vehicle. I prefer to use the springs F shewn in fig. 1 when it is
desired to have the elastic band D of small diameter. I find, however, that by
employing a band D of larger diameter as shewn in figs. 2 and 3, sufficient elasticity
is given without requiring the springs F, for which bolts G are substituted.
These bolts, as well as the bolts K connecting to the studs H, have nuts for adjusting
the elastic strain at the various parts of the leather, also the bolts K are made with
joints at L and are free to turn on the studs H so that they can accommodate their
positions to suit the relative strains of the parts. The bolts K.may be forged of
steel with their broad ends so flexible and elastic as to yield sufficiently in a
vertical direction, in which case the joints L may be dispensed with. The plate A
is curved downwards about the middle, so as to leave a free air space between it
and the leather B which is preferably perforated for ventilation. Obviously, the
shape of the plate A might be varied without departing from the character of my
invention. For example, the trough-like hollows in which the bands D lie, instead
of having circular curvature in plan might be straight, or instead of being
discontinuous as shewn in figs 1 and 2 they might be continued across the gap M
which is cut out merely for the purpose of saving weight. Instead of round elastic
bands D laid in hollows of the plate A, pieces of thick caoutchouc band D¹ may be
folded over the hinder edges of A as indicated in fig. 5.

page_text: 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 construction of saddles for bicycles, tricycles and such like vehicles wherein
a bent steel plate having the leather attached to its front, has at its hinder edge
elastic bands over which the leather is turned and adjustably secured to the
underside of the plate, substantially as and for the purposes herein set forth.
