An Improved Bicycle Saddle.
I, IRVING GERARD CHATFIELD of Cook Street Waterbury, New Haven
County, Connecticut, United States of America, Sheet Brass Worker, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a bicycle saddle composed of two frame pieces each
substantially oval in general plan outline and wider at their rear that at their
forward ends. Each of the frames has an oval opening corresponding to its outline
and has its outer edge higher than its inner edge. On the inner edge of each frame
there is a downwardly projecting lug to receive a screw bolt by which the frames
are secured to a saddle post. By means of an adjusting device consisting mainly of
a stirrup and set screw the inclination of the saddle relatively to the saddle post
may be determined, the said stirrup being pivotally attached to the depending lugs
of the frames. The frames are covered with a flexible material.

1, IRVING GERARD CHATFIELD of Cook Street, Waterbury, New Haven
County, Connecticut, United States of America, Sheet Brass Worker, 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 :-
In the drawing
Fig. 1 is a top view of one form which a bicycle saddle constructed in accordance
with this invention may assume. Fig. 2 a side elevation thereof.
Fig. 3 a top view of the saddle with the cover removed.
Fig. 4 a view of the saddle in section through line - of Fig. 1.
Fig. 5 a perspective view of the adjusting stirrup.
A, A', are two corresponding frame pieces made of heavy sheet metal bowed in
transverse section to give them rigidity and having their convex faces uppermost.
Each of these pieces is oval in general outline and has a large oval opening
corresponding to it in general form. The inner edges of the frame pieces extend
in substantially parallel lines while their outer edges which are considerably
higher than their inner edges, taper forward, where said frame pieces are much
narrower than they are at their rear ends which are rounded. The two sections
taken together may be compared in general outline to the outline of the hip bone.
The inner edge of each of these frame pieces is constructed with a depending
ear a the ears of the two pieces being applied respectively to the opposite faces of
the perforated forward end of the saddle post B and receive a screw bolt C provided
with a nut C¹ whereby said pieces are firmly clamped to the saddle post. Washers a¹

page_text: are interposed between the nut, the head of the screw bolt, and the ears a (Fig. 4).
An adjusting device comprising a stirrup D carrying a set screw E determines the
inclination of the saddle with reference to the saddle post, said stirrup being
pivotally attached by means of a pin d to the depending ears of the frame pieces
at a point to the rear of the screw bolt C (Fig. 2). The leverage imposed upon
the saddle will tend to tip it forward and downward on the screw bolt C so as to
bring the inner end of the screw E against the under face of the saddle post B
which is embraced by the stirrup. It will be clear that by turning said screw in or
out the inclination of the saddle may be regulated. The frame pieces A, A', are
covered by a flexible covering F, preferably of leather, and secured in place in any
suitable manner, as by straps f, f¹, (Fig. 4).
By giving the two pieces, which form the framework of the saddle, the general
outline of the hip bone, I secure a natural and comfortable seat, while by elevating
the outer edge of the frame pieces above their inner edges, the weight of the rider
is supported above the middle of the saddle in such a manner that the pubic or
inter-pelvic region is not compressed, thus avoiding injury and discomfort.
The seat when applied should be sufficiently slack to allow depressions conforming
to the contours of the body to be formed within the frame pieces and ou opposite
sides of their parallel inner edges.
I am aware that bicycle saddles constructed in two corresponding skeleton-like
members tapering from their rear ends forward and made independent of each other,
are not new, and that it is not new to provide the members of such a saddle with
a cover.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. A bicycle saddle having its framework composed of two frame pieces
substantially oval in general outline and wider at their outer rear than at their
forward ends, each having an oval opening conforming to its outline, and having
their outer edges higher than their inner edges which are substantially parallel,
substantially as described and shewn.
2. A bicycle saddle having its framework composed of two frame pieces, oval
in general outline, and tapering at their forward ends, having their outer edges
higher than their inner edges, which are substantially parallel, and constructed with
ears depending from their inner edges to receive a screw bolt, by means of which
they are clamped to a saddle post, substantially as described and shewn.
3. A bicycle saddle composed of two independent frame pieces, having their outer
edges higher than their inner edges and together having the general form of the
hip bone, a saddle post to which said frame pieces are adapted to be secured, and an
adjusting device connecting the saddle post and frame pieces at a point in rear of
the attachment of the latter to the former, substantially as described and shewn.
