An Improvement in the Construction of Frames for Cycles..
I, HERMAN MASON of No. 4 Minshull Street, Manchester, in the County of
Lancaster, Merchant, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is so to construct a tubular cycle frame that it may be
convertible so as to be adapted to be ridden by a lady or a gentleman.
For this purpose, instead of connecting the upper tube or bone of the ordinary
diamond-shaped frame rigidly to the top of the steering-bar socket, and to the top of
the seat post as usual, I attach the forward end of the said tube or bone to the top of
the steering-bar socket by means of a strong joint or hinge upon which it can be.
turned so as to raise the other or rear end up into the ordinary position for a gentleman,
or to lower the same when the machine is required to have an "open" frame so as to.
be used by a lady.
On the lower tube or bone of the frame, which as usual is fixed and extends.
from the bottom of the steering bar socket to the crank-axle bearing socket, and
fixed on or near to the latter, and also at the top of the tubular seat post,
I provide a short socket or other suitable means of attaching the rear end of the
upper tube or bone securely (when raised or lowered into either position) by
means of screws, bolts, slides, or other suitable locking device, so that the frame
of the machine can easily be converted from a "diamond" pattern into an.
open" frame, so as to be adapted for use by riders of either sex, and will remain
perfectly rigid in either form.
It will be obvious that the means employed for locking the rear end of the-,
upper tube or bone of the frame in either position may be varied to a considerable-
extent without departing from the main feature of my invention.

COMPLETE OF
An Improvement in the Construction of Frames for Cycles.
I HERMAN MASON, of No. 4 Minshull Street, Manchester, in the County of
Lancaster, Merchant, 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 :-
The object of this invention is so to construct a tubular cycle frame that it may
be convertible so as to be adapted to be ridden by a lady or a gentleman; and
the said invention will be readily understood on reference to the accompanying
drawings which is an elevation of so much of a bicycle as is necessary to illustrate-
my improvement.

page_text: Instead of connecting the upper tube or bone a of the ordinary diamond-shaped
frame rigidly to the top of the steering-bar socket b and to the top of the seat
post c as usual I attach the forward end of the said tube or bone a to the top
of the steering-bar socket 6 by means of a strong joint or hinge a* upon which
it can be turned so as to raise the other or rear end up into the ordinary
position for a gentleman, as shewn in full lines, or to lower the same when the
machine is required to have an "open" frame so as to be used by a lady, as
shewn by dotted lines on the drawing.
On the lower tube or bone c of the frame, which as usual is fixed and extends
from the bottom of the steering-bar socket b to the crank-axle bearing socket c¹
and fixed on or near to the latter, or near to the bottom of the seat post 61 as
shown, and also at the top of the tubular seat post b¹, I provide a short socket or lug
or lugs as seen at d and e or other suitable means of attaching the rear end of the
upper tube or bone a securely (when raised or lowered into either position) by means
of screws, bolts, slides, or other suitable locking device, so that the frame of the
machine can easily be converted from a "diamond" pattern into an "open" frame, so
as to be adapted for use by riders of either sex, and will remain perfectly rigid in
either form.
It will be obvious that the means employed for locking the rear end of the upper
tube or bone of the frame in either position may be varied to a considerable extent
without departing from the main feature of my invention.
For example the upper tube or bone may be straight as shown by the full lines on
the drawing, or curved as shewn by the dot and dash lines, and the point of attachment
thereof when in the position suitable for a lady rider may vary according to various
styles of frame.
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 1
claim is :-
An adjustable upper tube or bone pivotted at or near the upper part of the steering
bar socket and capable of being fixed in such positions in the frame of the bicycle
that the said bicycle can be converted or adapted to the requirements of a rider of
either sex substantially as hereinbefore described and illustrated by the annexed
drawing.
