Improvements in Saddles for Bicycles, Tricycles, and other similar
purposes.
I, WALTER BRAMPTON, of Chesfield, Great Malvern, in the County of Worcester,
Gentleman, do hereby declare the nature of my said invention to be as follows:-
My invention has for its object improvements in saddles for bicycles, tricycles,
and other similar purposes which are so constructed as to form an easier and
more comfortable seat than the ordinary saddle and is specially adapted to
minimize the effect of concussion.
My new saddles are built upon a base plate which I generally stamp or press
from a steel or other metal plate the outside form being very much that of the
configuration of saddles now in use. This plate is stamped, pierced, and manipu-
lated so as to leave two considerable holes under the tuberosities or tuber ischium
of the seat and a long slot is cut out of the plate between these holes which leaves
strips of metal running longitudinally on each side of the boss which fits on the
L pin, and the back part of the frame is curved inwards so as to give a more cor-
rect shape as agreeing with the seat. In stamping or cutting out the centre hole
sufficient metal is left by the side strips to form flanges to carry the side rails
upon which the boss is hung for adjustment. The remaining metal or that form-
ing the frame of the base plate is formed into a U or curved or hollow section
so as to impart the necessary stiffness to this light under frame upon which the
saddle is built. Or this base plate may be made from tubing either round or
pressed Ushape in cross section & may be either flat or formed somewhat to
the shape or contour desired for the seat surface whether for a lady or gentleman's
saddle. Around and upon the middle of the frame or strips of the plate form-
ing the base I mount helical or spiral springs and these are so arranged around
the edge as to leave considerable space under the tuber ischium bones of the
seat. These springs are run around the back and around the edges of the front
and also up each side of the boss leaving the centre space and the two side spaces
as previously explained and the springs may be coiled or screwed one into the
other or they may be mounted separately, but in either case they are so connected
by a top covering of leather or textile or other material as to maintain the large
number of small springs used in sympathetic connection the one with the other
the ends of each spring being rivetted or eyeletted or otherwise fastened top and
bottom so as to be well secured against displacement. If the base plate used is
an unshaped one or flat the springs may be made of varying lengths to give
the top shape or contour but if the base plate is made the same shape as the
top is required all the springs may be of the same length. I then as a covering
stamp or press or otherwise form a leather or other covering and line the same
with a pad, which covering may be either fastened down to the spring covering
I thus obtain a saddle com-
or the edges may be attached to the under frame.

tuberosities of the seat are maintained or supported in two slings, the slings
themselves being supported upon abutments or walls composed of a series of

COMPLETE SPECIFICATION.
Improvements in Saddles for Bicycles, Tricycles, and other similar
purposes.
I, WALTER BRAMPTON, of Chesfield, Great Malvern, in the County of Worcester,
Gentleman, do hereby declare the nature of my said invention 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 improvements in saddles for bicycles, tricycles,
and other similar purposes which are so constructed as to form an easier and
more comfortable seat than the ordinary saddle and is especially adapted to
minimize the effect of concussion.
In order that my invention may be more clearly understood and more easily
carried into practical effect I have appended hereunto sheets of drawings upon
which I have shewn examples of my saddle.
Figure 1 is a perspective view of my saddle complete.
Figure 2 is a side view of my saddle with the cover removed.
Figure 3 is a back view of Figure 2.
Figure 4 is a similar view to Figure 2 shewing a modified form of my saddle.
Figure 5 is a plan view of Figure 2 shewing a portion of the seat removed.
Figure 6 is a plan view of the stamping of the base plate.
Figure 7 is a plan view shewing a modified form of base plate.
Figure 8 is an elevation shewing a further modified form of base plate.
Figure 9 is an underside plan view of Figure 8.
Figure 10 is a section through a specially formed framing.
In carrying my invention into practice I build my saddles upon the specially
shaped base plate A which I generally stamp or press from a steel or other metal
plate the outside form being very much that of the configuration of saddles now
in use. This plate is stamped pierced and manipulated so as to leave two con-
siderable holes K K under the tuberosities or tuber ischium of the seat and the
long slot a is cut out of the plate between these holes leaving the strips of
metal and a running longitudinally on each side of the boss B which fits
on the pin and the back part 6 of the frame is curved inwards so as to give
a more correct shape as agreeing with the seat as shewn at Figures 5 6 and 7. In
stamping or cutting out the centre slot sufficient metal is left by the side strips
a and as so that when bent down they form flanges to carry the side rails b¹ upon
which the boss B is hung for adjustment. The remaining metal or that form-
ing the frame of the base plate is formed into a U or curved or hollow section
so as to impart the necessary stiffness to this light under frame upon which the
saddle is built. Or this base plate may be made from tubing either round or
pressed shape in cross section as shewn at Figure 10 and it may be either flat
as shewn at Figures 1, 2, and 3 or formed somewhat to the shape or contour
desired for the seat surface whether for a lady or gentleman's saddle as shewn at
Figure 4. Or I may form the base plate as shewn at Figures 8 and 9. In this

page_text: case I dispense with the back portion and also the strips at anda and on the
underside of this plate I secure the wire or steel frame J to which the saddle
clip or boss B is attached.
Around and upon the middle of the frame or strips of the plate forming this
base I mount a number of helical or spiral springs S which are so arranged
around the edge as to leave considerable space K K under the tube ischium bone
of the seat. These springs are run around the back and around the edges to
the front and also up each side of the boss leaving the centre space and the two
side spaces as previously explained and as clearly shewn at Figure 5, and these
springs may be coiled or screwed one into the other or they may be mounted
separately but in either case they are so connected by the top covering D of
leather or textile or other material as to maintain the large number or small
springs used in sympathetic connection the one with the other the end of each
spring being connected by the eyelets or rivetted or otherwise fastened to the
base plate and the covering 1) so as to be well secured against displacement and
arranged in two principal groups around the holes K, K. If the base used is
an unshaped one or flat as shewn at Figures 1, 2, and 3 the springs may be
made of varying lengths to give the top shape or contour but if the base plate
is made the same shape as the top is required as shewn at Figure 4 all the springs
may be of the same length. I then stamp or press or otherwise form the leather
or other cover E and line the same with a pad and this cover may be either
fastened down to the spring covering D or it may be attached to the under frame.
I thus obtain a saddle composed of a large series of small springs arranged in
such a manner that the tuberosities of the seat are maintained or supported in
two slings the slings themselves being supported upon abutments or walls com-
posed of a series of springs in sympathetic relationship to each other so that it
becomes impossible for the tuberosities of the seat to receive blows of any descrip-
tion other than through the slings and springs supporting the the slings and by
these means I form a remarkably easy and safe saddle. It will be evident that if the
holes K are not formed in the foundation plate A that the springs may still be
so arranged as to constitute with the covering slings for the protruding portions
of the seat with similar effect. The manner of mounting the springs to the base
and to the cover is such as before explained that each spring is capable of the
utmost possible travel or compression which affords the maximum elasticity to
my saddles.
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
:
CLAIMS.
First The improvements in saddles for bicycles tricycles and other similar
purposes consisting essentially of a base plate formed to support a series of
springs arranged and extending around the seat so as to form walls for sus-
pending slings to carry the tuberosities of the seat and constructed with and
secured to the flexione covering to which the springs are securely fastened sub-
stantially as herein set forth and as shewn upon the drawings.
Second: In saddles for cycle forming the foundation thereof from a such
like plate as shewn in plan at Figures 5 and 6 with inner spaces or holes around
which the springs are fixed so as to suspend the flexible seat portion upon the
walls formed by the springs, portions of the said plate being turned down to
carry the rails substantially as herein set forth and shewn.
Third: In saddles for cycles forming the foundation from bent tubes as
shewn at Figures and 10 whether the tube is left round or flattened or moulded
into shape and upon which foundation frame the springs are directly fixed
with spaces left for the tuberosities of the seat substantially as set forth and shewn.
Fourth In saddles for cycles forming the foundation thereof from a such

page_text: like plate as shewn at Figures 8 and 9 with inner spaces or holes around which
the springs are fixed and securing under the said plate a wire or other metal
frame such as J to carry the boss or clip B substantially as herein set forth and
shewn,
Fifth The improvements in saddles herein set forth and shewn upon the
drawings consisting of a series of springs connected together around and under
the seat by flexible material, the lower ends of the springs being connected to
the base plate and in sympathetic connection with each other.
