An Improved Frame for Bicycles.
I, HENRY COOPER, of 7, Norfolk Street, Saint Pauls, Bristol, Cabinet Maker,
do hereby declare the nature of this invention to be as follows:-
This invention relates to bicycles, and consists in an improved frame therefor.
The improved frame consists of a pair of members of steel or wood bent to a
suitable shape, placed abreast and secured together at suitable points, by bolts or
other means. English ash and American rock elm and the like are examples of
suitable kinds of wood in which to construct the members. Each member is bent
to form a pair of bows of which the larger is at the rear, and the smaller at the
front. The rear wheel runs between the members, and the front wheel is clear of
them. The saddle pillar is carried on the frame, and the steering pillar socket is
held between the members at the front bow.
Each member crosses itself in advance of the rear wheel and is, at its ends,
secured to itself by bolts screws or other suitable means.

I, HENRY COOPER of 7 Norfolk Street Saint Pauls, Bristol, Cabinet Maker
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:-
My invention relates to cycle frames, and more particularly to bicycles for
ladies. The improved frame is constructed of steel tubing or wood, bent to a
special form; and when wood is used for the frame I employ English ash, or
American rock elm, and like timber suitable for bending.
The outlines of my frame are such as produce a very strong and elastic
construction with minimum of weight, and the objectionable vibration so common
in the ordinary straight line frame in general use is obviated. In actual practice
the described frame has the effect of a spring frame, without the complication of
springs and mechanism.
My improved frame is constructed as shown in the accompanying drawings.
Fig. 1 is a side elevation of one of the bent members used in the frame, and two
of such members are placed abreast of each other with sufficient space at the rear
for the driving wheel to run clear between the two members.
The frame members are looped at a and at 6; and the loop a is disposed at the
rear of the cycle; the smaller loop b is disposed so as to carry the steering pillar
socket above the front wheel. The ends of each member cross themselves at d,
and are there secured by screws or bolts, or similar fastenings.

page_text: In Fig. 2, two of the members described are placed side by side with a suitable
space between, and the said space is preserved by means of distance pieces secured
between the members. At e a projection is formed on one of the said distance
pieces, and a hole in the said projection is provided for the reception of the
saddle pillar f.
The space between the members at the rear of the cycle allows the driving
wheel to run clear between the said members, but the said space diminishes
towards the loop b at the front of the cycle.
The two members are securely clamped together by means of bolts or screws g, g.
or other clamping device.
Ath the two members are close together, and are clamped upon the steering
pillar socket c and the frame is recessed suitably to hold the said socket perfectly
rigid.
Fig. 3 is a plan of the described frame, and shows the pair of members A, B,
clearly..
The hole for the saddle pillar is shown at i through one of the distance pieces, j;
the driving wheel k, clamping bolts or fastenings g, g, the recesses ll in the loops b
for the steering pillar socket. The said socket omitted for convenience of
illustration.
The improved frame described is similarly constructed with lengths of steel
tubing, the two members being disposed adjacent to each other as described and
suitably connected to form a complete frame by means of brazed joints, or by bolts
or screws as may be convenient.
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.
1. In an improved bicycle frame, the combination of two members looped as
described; the members connected as shown to form an elastic frame.
2. In an improved bicycle frame, the combination of two looped members formed
of steel tubing, or wood; and disposed as shown.
3. In an improved bicycle frame, the combination of two looped members
adjacent one to the other, and bolt or screw clamped to hold the steering pillar
socket substantially as shown and described.
