An Improvement in or relating to Cycle Seats and their Frames.
I, WALTER FLETCHER, of 39, Lyndhurst Grove, Peckham, County of Surrey,
Gunsmith, do hereby declare the nature of this invention to be as follows:-
This invention has for object :
1. The construction of cycle seat frames from rigid metal with fore and aft ends
only. The front of the frame is formed with a peak and the back with a rounding,
a full opening being between them. The ends are supported on a stretcher bar
for attachment to the pin of the machine.
2. To making the seat proper, or the foundation of such, of stout yet very pliable
india rubber cut or moulded to shape, the edges of which may be strengthened by
canvas and may be arranged to be stretched over the skeleton frame ends, or be
fixed by a back lacing, or be clamped as desired after being drawn over the front
peak.
The rubber seat proper or the foundation for one, as before referred to, may be
thickened at parts and may have side curtains and be perforated or gratinged for
ventilation and for keeping the seat cool, but it may be cushioned or covered with
leather felt or a canvas cover, or of other material.
If the seat be clamped to the frame, I prefer to form a groove with an inner
rib and a corresponding notch between which the seat be fixed.

I, WALTER FLETCHER, of 39, Lyndhurst Grove, Peckham, County of Surrey,
Gunsmith, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement:―
This invention relates to an improvement in cycle seats and their frames the
object being and as shown on the annexed drawings Figures 1 and 2, side view
and under plan respectively.
1. The construction of cycle seat frames A from rigid metal with fore and aft
ends B, C, only. The front B of the frame is formed with a peak D and the back

page_text: with a rounding E, a full opening being between them. The frame is supported on
a stretcher bar F for attachment to the L pin G of the machine.
2. To making the seat proper H or the foundation of such of stout yet very
pliable india rubber cut or moulded to shape, the edges of which may be strength-
ened by canvas and may be arranged to be stretched over the skeleton frame
ends D, E, or be fixed by a back lacing or be clamped as desired after being drawn
over the front peak D.
The rubber seat proper H or the foundation for one as before referred to, may be
thickened at parts and may have side curtains I, I, and be perforated or gratinged
for ventilation and for keeping the seat cool, but it may be cushioned or covered
with leather, felt or a canvas cover or of other material.
Figure 3 is a transverse sectional view of my plain elastic cycle seat with inflated
ribs JJ, or channels on or in the upper surface for the rider to sit on as a soft
yielding body and be slightly compressed before his actual weight is borne by the
seat proper which then yields as a cushion to give ease and comfort while travelling.
Figure 4 shows a similar section of an elastic cycle seat with the inflated channels
and ribs from the under surface.
The frame is preferably of steel and springless in itself nor is any of the metallic
portion, thus throwing all the elasticity and springyness in the seat proper of plain
soft cured rubber stretched over a metal skeleton frame.
I have shown the rubber saddle seat plain on the surface but it may be perforated
or otherwise as found desirable and instead of being stretched it can be drawn over
and then be laced tightly to fix the edges over the ends only of the skeleton frame,
or the frame may be made extensible for exerting pressure against the end edges of
the seat and of the curtain.
The cured soft rubber seat may vary in thickness to give extra strength where
necessary with a gradual thinning down to those parts less liable to injury and
instead of the ribs being inflated they may be solid to resist undue compression and
be on top and also on bottom.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. The manufacture of a soft cured rubber seat for a cycle stretched over and
suspended from and secured to fore and aft portions of a rigid frame, the inter-
vening underspace being clear as set forth and as shown on the annexed drawings.
2. The improved manufacture of a cycle seat consisting of a hammock suspended
seat proper of soft cured rubber affixed over and to a skeleton frame composed of a
peak at the fore part and a rounded part at the rear such two parts being connected
rigidly to a rigid spanned bridge or inverted arch as represented in the annexed
drawings and as described.
