PROVISIONAL SPECIFICATION.
Improvements in Combination Saddles and Springs for Velocipedes.
I, ARTHUR ADAMS, of Monument Road, Birmingham, in the County of Stafford,
Manager, do hereby declare the nature of this invention to be as follows:-
My invention relates to a novel combination and construction of parts, forming a
self-contained combined saddle and spring for velocipedes.
I take a piece of leather of the usual shape to fit the seat, and on the rear of
it fix a cantle plate having a depression at its centre to give a longitudinal grooved
form to the rear part of the seat. The usual staples or eyes for attaching a bug or
pouch are formed as part of the cantle plate. On to the front of the leather seat is
fixed a small depending plate provided with a circular hole to receive the threaded
end of a central bar, or its equivalent, forming a rigid under frame for the seat. On
the threaded end of this bar are screwed two nuts, the one-having a milled end-
behind the plate, and the other-an ordinary hexagon nut-before the plate. These
two nuts provide the screw tension for adjusting the leather seat. On to the cantle
plate equidistant on each side of the centre thereof, and on to the forward end of the
central bar, or its equivalent, I attach a coiled spring. These three springs support
the leather seat and are themselves fixed to, and supported by, a foundation plate
suitably formned to receive them. At about the centre of this foundation plate a
curved depression is made, giving it a segmental form. The top of the socket, or its
equivalent, to receive the seat pillar is recessed to fit this segmental part of the
foundation plate, and the engaging faces of both parts are serated, or otherwise
fashioned, to ensure their firm interlocking when fixed the one to the other by means
of a stud and nut, or bolt. To give the nut or bolt head a good grip, a suitable
washer is interposed in the concave part of the segment in the foundation plate.

In order that my invention may be fully understood I herewith append a drawing
showing how my invention is carried into practical effect. Figure 1. is a view in
side elevation partly in section of my improved combination saddle and spring and
Figure 2 is a view in end elevation thereof. Eigures 3 and 4 are views in side
elevation partly in section-and end elevation, respectively, of a modified form of
my improved combination saddle and spring.
In this
Throughout these views similar parts are marked with like letters of reference.
Referring to the drawings. A designates the leather seat cut of the usual or any
other convenient form or shape. B designates the cantle plate rivetted or otherwise
fixed to the rear end of the leather seat A, and either formned with a depression a
in the centre of its length to give a longitudinal grooved form to the rear part of
the leather seat A as illustrated by Figures 1. and 2 or formed flat as illustrated.
by Figures 3 and 4.
C designates the depending plate rivetted or otherwise fixed to
the forward end of the leather seat A. D designates the central bar or its equivalent
the rear end of which is-fixed-to-the cantle plate. B.and the forward end is supported
by the plate C and is threaded to receive two nuts E and E the former-preferably
a milled edged nut to be operated by hand-adapted to operate against the rear side
of the plate C to stretch the leather seat A and take up the slack thereof, and the
latter an ordinary hexagon nut-adapted to bear against the front side of the plate C
and lock it against the nut E.after the necessary adjustment of the leather seat A has
been effected. In the modification illustrated by Figures 3 and 4 the bar D or it's
equivalent is forked to adapt it to be fixed to the cantle plate B at two points. The
forward end of the bar may then either be made circular in form and threaded as and
for the purpose hereinbefore described, or it may be adapted to receive the threaded
end of a fang C¹ formed on the plate C as illustrated by Figures 3 and 4.
case the nut E is placed to operate against the forward end of the bar D for the
purpose of stretching the leather seat A. F. F. F. designate the three coiled springs,
one fixed to the under side of the forward end of the bar D, and the other two to the
under side of the cantle plate B by suitable bolts and nuts 1, f,f, as illustrated.
G designates the T-shaped foundation plate to support the springs F, F, F, which
are fixed thereto by suitable bolts and nuts f¹, f, f, and G¹ designates the segmental
depression formed at or about the centre of the length of the said foundation plate,
and having its convex side on the under part of the said plate. yg etc. designate
the teeth or serations on the convex side of the segmental part, G1 of the
plate G. H designates the socket adapted to fit on the seat pillar and to be fixed
thereto by the set screw h. The part of the socket H adapted to engage with the
toothed or serated face of the segmental depression G¹ is provided with one or more
engaging teeth or serations h¹ to ensure the firin interlocking of the two parts when
locked together by the bolt H¹, passing through the longitudinal slot g' in the
segmental depression G¹ and the nut h2 screwed down on the said bolt. J designates
the convex shaped washer adapted to fit in the concave part of the segmental depres-
sion G. By constructing the foundation plate G and socket H in the manner
described the position of the foundation plate may be varied to alter the tilt of the
saddle as desired without altering the longitudinal position of the saddle on the machine.
I do not limit myself to the particular forin or shape of the socket H as it will require
to be varied to suit the various seat pillars used on the different makes of machines.

page_text: I am aware that prior to the date of my invention the leather seats of saddles
have been inade adjustable by tension devices, also that they have been supported
on three coiled springs, and further that the foundation plates have been curved so that
by altering the position of the saddle on its support the tilt of the saddle could
be varied, I therefore do not claim any of these devices broadly, but having now
particularly described and ascertained the nature of my said invention and in what
inanner same is to be performed I declare that what I claim is ;-
1st. A combination saddle and spring for velocipedes, the several parts of which
are combined, arranged, and operate, substantially as and for the purpose set forth.
2nd. In a combination saddle and spring for Velocipedes, the combination with
the leather seat A, cantle plate B, and depending plate C, of the bar D or its
equivalent rigidly fixed to the cantle plate B and adjustably attached to the plate C,
the springs F, F, F, supporting the cantle plate B and the bar D, the foundation
plate G having a segmental depression G₁ on its underside, the teeth or serra-
tions gg etc. on the convex side of the said depression, the socket H having a
concave surface with one or more teeth h¹ adapted to receive the segmental
depression G¹, of the bolt H and the convex washer J, all combined, arranged,
and operating as and for the purpose set forth.
3rd. In a combination saddle and spring, the combination with the leather seat A
the bar D or its equivalent and the three coiled springs F, F, F, of the foundation
plate G having a segmental depression G at or about the centre of its length
adapted to engage with a corresponding depression in or on the socket by which
it is mounted on the seat pillar, and having interlocking teeth or serations on the
engaging faces of the two parts whereby the position of the foundation plate with
respect to the supporting socket may be varied to alter the tilt of the saddle
without altering its position longitudinally, as set forth.
Dated this 21st day of October 1889.
