Improvements in Frames for Bicycles and Tricycles.
We, CHARLES FRANCIS YOUNG of Oldham Road, Manchester in the County of
Lancaster, Cycle Makor and CHRISTOPHER BULLEN of Flora Street, Lower Broughton,
Salford, in the said County, Cycle Maker do hereby declare the nature of this
invention to be as follows:-
This invention is designed to render the machine readily convertible either into a
gentleinan's or ladies machine.
We make the seat pillar tube curved to the arc of a circle with the centre at the
top of the steering head and securely affix the bottom of this tube or stay to the
bottom bracket by an additional stay or other device and also preferably to the front
down tube to give the desired rigidity.
The top bar we pivot to the steering head at one end aud cover the joint with a
suitable cap or cover. The other end of this bar we form with a clip or socket to
embrace the seat pillar tube and which can be moved up and down thereon to any
desired position from that of a top bar of a gentleman's machine to the drop bar of
a lady's machine or vice-versa. A suitable lock or clamp may be applied to secure
is at the desired positions.

Improvements in Frames for Bicycles and Tricycles.
We CHARLES FRANCIS YOUNG, of 2 Baker Street, New Islington, Manchester in the
County of Lancaster, late of Oldham Road, Manchester in the County of Lancaster,
Cycle Maker, and CHRISTOPHER BULLEN, of Flora Street, Lower Broughton, Salford, in
the said County, Cycle 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:-.
This invention is designed to render the machine readily convertible either into a
gentleman's or lady's machine.
The invention consists essentially in constructing the frame of the machine with
the seat pillar tube curved to the arc of a circle (with its centre the top of the
ball-head) and a pivoted top har capable of sliding up and down thereon to be
secured either to the top or bottom of the curved seat pillar tube as it may be
required in a horizontal or inclined position.
It will be fully described with reference to the accompanying drawings.
Fig. 1. Side elevation of bicycle constructed in accordance with the invention.

page_text: Fig. 2. Plan of parts of same.
The seat pillar tube A, we curve to the arc of a circle with its centre at a near
the top of the ball-head B. The curved seat pillar tube A is brazed or otherwise
securely fixed at the bottom end as shown, and is rendered more rigid by the
additional stay D.
The top bar E is pivoted or hinged to the ball head top lug b, so that it may be
dropped from the horizontal position to the inclined position shown in dotted lines.
At the other end it is formed with a socket e which embraces the curved seat pillar
tube A and slides up and down upon it.
The socket e is provided with a clip and bolt el by which it can be tightened up
upon the seat pillar tube, and the seat pillar tube A is preferably inade with an
enlargement or bush at each end over which the socket e fits so that it may slide
easily over the other length of the tube.
The seat pillar bracket F may be made with a centre aperture to receive the seat.
pillar G, or the seat pillar G may be curved to correspond with the curve of the seat
pillar tube A, and fit into the interior of the tube in the ordinary way.
The invention may be applied either to a single or tandem machine.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, we declare that what we
claim is :-
1. A cycle frame constructed with a curved seat pillar tube, and a bar pivoted to
the ball head, which may be placed either in a horizontal or inclined position,
substantially as and for the purpose described.
2. In a cycle frame the combination with a drop bar pivoted to the ball head of a
curved seat pillar tube and a socket on the end of the drop bar, which embraces the
tube and may be moved from one end to the other, substantially as and for the
purpose described and shown.
