Improvements in the Saddles or Seats of Bicycles, Tricycles, and
other Velocipedes.
I JAMES ALFRED LAMPLUGH of No. 135 Great Colmore Street, Birmingham
in the County of Warwick, Manufacturer do hereby declare the nature of this
invention to be as follows:-
My invention relates to the leather tops of the saddles or seats of bicycles,
tricycles and other velocipedes, and has for its object to give a special elasticity or
yielding property to a particular part or particular parts of the said leather tops,
thereby removing the sense of pressure experienced by some riders at different
parts of the saddle.
When seated on the saddle or seat of a bicycle, tricycle or other velocipede, the
weight of the rider is mainly borne by that part of the leather top immediately
under the ischia of the pelvis and the resistance of the leather at that part often
distresses the rider. In order to relieve the rider of this sense of pressure I make at
the rear of the leather top of the saddle or seat and on each side of the middle line
of the said leather top, that is, at the parts immediately under the ischia, a series
of slits crossing a common centre so as to form a series of tongues in the leather
top, the points of which tongues meet at the common centre. On the underside of
the leather top I attach a disc of vulcanized india rubber at each of the slit parts,
the said disc of vulcanized india rubber being fixed to the leather top either by
circular stitching or by india rubber cement or by both. Pressure on the part
having the crossing or star like slits, depresses the leather tongues of the said part
producing a slight concavity and preventing the sense of pressure which would
have been produced but for the yielding of the leather in consequence of the slits
described. When pressure is removed from the slitted parts of the leather top,
the vulcanized india rubber discs underneath restore the leather top to its normal
figure and the configuration of the top of the saddle differs in no respect from that
of an ordinary saddle.
Although the parts of the leather top of the saddle or seat to which my invention
is especially applicable are the parts have herein before referred to, yet other
parts of the leather top of the saddle or seat may be slit and treated in the manner
described to suit the requirements of different riders.

Improvements in the Saddles or Seats of Bicycles, Tricycles, and

I JAMES ALFRED LAMPLUGH of No. 135 Great Colmore Street, Birmingham
in the County of Warwick Manufacturer, do hereby declare the nature of the said
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :—

or yielding property to a particular part or particular parts of the said leather tops
thereby removing the sense of pressure experienced by some. riders at different
barts of the saddle.

page_text: When seated on the saddle or seat of a bicycle, tricycle, or other velocipede,
the weight of the rider is mainly borne by that part of the leather top immediately
under the ischia of the pelvis and the resistance of the leather at that part often
distresses the rider. In order to relieve the rider of this sense of pressure I make
at the rear of the leather top of the saddle or seat and on each side of the
middle line of the said leather top; that is, at the parts immediately under
the ischia of the rider, a series of slits crossing a common centre so as to
form a series of tongues in the leather top, the points of which tongues meet.
at the common centre. On the underside of the leather top attach a disc
of vulcanized india rubber at each of the slit parts, the said disc of
vulcanized india rubber being fixed to the leather top either by circular stitching
or by india rubber cement or by both Pressure on the part having the crossing
or star like slits depresses the leather tongues and the india rubber disc of the said
part, producing a slight concavity and preventing the sense of pressure which
would have been produced but for the yielding of the leather in consequence of the
slits and india rubber discs described. When pressure is removed from the slitted
parts of the leather top, the vulcanized india rubber discs underneath them restore
the leather top to its normal figure and the configuration of the top of the saddle
differs in no respect from that of an ordinary saddle.
Figure 1 of the accompanying drawings represents in side elevation, partly in
section and Figure 2 in plan the leather top of a saddle or scat containing my
improvements;
Figures 3 and 4 represent in section and Figure 5 in plan a portion of the
leather top drawn to a larger scale;
a is the leather top of the saddle or seat and b, bare the series of tongues made
from the said top by a series of radial or star like slits crossing a common centre,
the points of the tongues b, meeting at the common centre as illustrated in the
drawing. The ends of the slits joining the leather top may be provided with
perforations for ventilating the saddle; c, c are the discs of vulcanized india rubber
under the star like slits or tongues at 6 for supporting the said slit parts or tongues
and acting as yielding. pads. These india rubber discs e, e may be secured at their
edges to the leather top by circular stitching or by india rubber cement or
by both.
When there is no pressure upon the saddle top a the star like slitted parts or
tongues b, have the normal figure of the saddle top, but when pressure is put
upon the said slitted parts or tongues by the rider they are depressed and with
them the india rubber supporting discs e, c. A concavity is thereby produced in
the leather top a by the yielding of the star like slitted parts or tongues b, band
india rubber disc c as illustrated in Figure 4 and the sense of pressure experienced
by riders on the ischia of the pelvis is thereby removed.
The india rubber discs c, e under the star like slitted parts or tongues, acting
as yielding pads restore, by their elasticity the leather top to its normal figure on
the removal of the pressure.
Figure 6 represents partly in longitudinal section and partly in elevation and
Figure 7 in plan the leather top of a saddle made according to my invention in
which leather top instead of a series of star like slits, a series of parallel and
curved slits d, d is made and arranged at the rear half of the saddle top in the
manner best seen in Figure 7, a single piece of india rubber or yielding pad
marked e, fixed under the slitted portions of the leather top by sewing or cement,
supporting the slit parts of the leather top as described with respect to the star
like slitted parts. The action of this arrangement is the same as that first
described and represented.
Although the parts of the leather top of the saddle or seat to which my invention
is especially applicable are the parts I have hereinbefore referred to and shown in
the accompanying drawings yet other parts of the leather top of the saddle or
seat may be slit and treated in the manner described to suit the requirements of
different riders; for example the star like slitted parts or tongues and their india

page_text: rubber supporting discs or yielding pads may be applied to the front of the
leather top.
Instead of fixing the vulcanized india rubber discs or pads under the star like
slitted parts or tongues b, b and parallel and curved slitted parts d, d of the leather
top, the said india rubber discs or pads may be fixed above the said slitted parts or
tongues. In this case I make depressions in the leather top, where the slits are to
be made, below the level of the said top and fix the india-rubber discs or pads in
the said depressed slitted parts so that the said discs do not project beyond the
surface of the leather top.
Or the parts of the leather top where the special elasticity or yielding property
is required may be reduced in thickness so as to make them capable of readily
yielding when pressure is put upon them, the yielding or thin parts of the leather
top being provided with the india rubber discs or pads fixed either below or above
them as described with respect to the star like and other slitted parts.
Having now particularly described and ascertained the nature of my invention
and the manner in which the same is to be performed I declare that I claim as my
invention of " Improvements in the saddles or seats of bicycles, tricycles and other
velocipedes ;".
-
Giving the leather tops of saddles or seats a special clasticity or yielding
property at the parts immediately under the ischia of the pelvis of the rider or
other parts of the leather top to suit the requirements of different riders, by making
in the said leather top a series of radiating or star like slits or parallel and curved
slits or other like slits thereby forming a series of yielding parts, or reducing the
thickness of certain parts of the leather top so as to make them capable of readily
yielding when pressure is put upon them, the said slitted tongues or parts or thin
yielding parts in the leather top being used in combination with discs or pieces of
vulcanized india rubber fixed underneath or over them substantially as and for the
purpose hereinbefore described and illustrated in the accompanying drawings.
