Improvements in connection with the Frames of Velocipedes and
in the Manufacture of the same.
I, GEORGE WILLIAM HAWKER of the Firm of Hawkers Limited, of 48, Spencer
Street, Birmingham, in the County of Warwick, Manufacturers, do hereby declare
the nature of my said invention to be as follows:-
My invention has for its object improvements in connection with velocipedes
and in the manufacture of the same by which I am enabled to easily and quickly
convert a gentleman's "safety" into a ladies machine or vice versa.
In carrying my invention into practice I form the top ball head or steering
socket lug with a double socket, one above the other. The top socket receives one
end of the top or parallel tube of a gentleman's safety frame and this end of the tube
is secured into the socket by a nut and bolt or their equivalent. Or instead of
forming the top ball head lug with a double socket I may attach a lug to the end
of the top or parallel tube provided with two ears or projections which may be
attached to the ordinary top ball head lug by a nut and bolt or equivalent. The
other end of this parallel tube is fixed into one of the sockets of the seat pillar lug
in the ordinary manner, the other socket of this lug has a short piece of tube fixed
into it and this short piece of tube fits into the socket of the seat pillar lug of a
ladies frame which lug is connected to one end of the tube fitting into the bottom
bracket. The back stays of the frame are also connected to this lug in the ordinary
manner. The lower socket on the top ball head lug receives one end of the tube
which passes down to a lug fixed at the bottom of the seat pillar tube in the
ordinary manner when building a ladies frame. The seat pillar passes down the
lug at the rear end of the top or parallel tube down the short piece of tube and into
the lug to which the back stays are fixed. It will thus be readily understood that
by disconnecting the top parallel tube from the top ball head lug the machine
can instantly be converted into a ladies' safety. The short piece of tube which is
fixed into the seat pillar lug connected to the top tube enables this tube to be
parallel when used as a gentleman's "safety."

Improvements in connection with the Frames of Velocipedes and
in the Manufacture of the same.
I, GEORGE WILLIAM HAWKER, of the Firm of Hawkers Limited, of 48, Spencer
Street, Birmingham, in the County of Warwick, Manufacturers, do hereby declare

page_text: the nature of my said invention and in what manner the same is to be performed
to be particularly described and ascertained in and by the following:
My invention has for its object improvements in connection with velocipedes
and in the manufacture of the same by which I am enabled to easily and quickly
convert a ladies safety into a gentleman's machine or vice versa.
In carrying my invention into practice I form the top ball head or steering
socket lug with a double socket one above the other. The top socket receives one
end of my
detachable niember and this end of the member is
secured into the socket by a nut and bolt or their equivalent. Or, instead of
forming the top ball head lug with a double socket I may attach a lug to the end
of my detachable member provided with two ears or projections which may be
attached to the ordinary top ball head lug by a nut and bolt or equivalent. The
other end of this detachable member is fixed into one of the sockets of a seat pillar
lug in the ordinary manner the other socket of this lug has a short piece of tube
fixed into it and this short piece of tube fits onto or into the socket of the seat
pillar lug of a ladies frame which lug is connected to one end of the tube fitting
into the bottom bracket. The back stays of the frame are also connected to this
lug in the ordinary manner. The lower socket on the top ball head lug receives.
one end of the tube which passes down to a lug fixed at the bottom of the seat
pillar tube in the ordinary manner when building a ladies frame.
The seat pillar passes down the lug at the rear end of the top or parallel tube
down the short piece of tube and into the lug to which the back stays are fixed.
It will thus be readily understood that by disconnecting the top parallel tube from
the top ball head lug the machine is instantly converted into a ladies safety.
The short piece of tube which is fixed into the seat pillar lug connected to the top.
tube enables this tube to be parallel when used as a gentleman's safety.
In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto a double sized sheet of drawings
upon which I have illustrated examples of my improvements.
Figure 1 shews the upper portion of the frame of a ladies cycle with my im-
provements applied thereto.
Figure 2 is a similar view to Figure 1 shewing a slight modification of my
improvements.
.
Figure 3 shews the member D as shewn at Figure 1 detached.
Figure 4 is a part sectional view shewing a modified form of the back portion of
the frame.
Figure 5 is a similar view to Figure 4 shewing a further modification.
In carrying my invention into practice I form the lug ď¹ which is fixed on the
front end of the top or parallel tube or member D with the ear or projections d
and these ears or projections fit around the socket of the top lug h¹ of the ball
head or steering socket H and on the other end of this member D I fix the lug d
also fixed in the socket d' of this lug in the supplemental tube or member E
which tube fits onto the usual seat pillar lug F of a ladies cycle. Or this
member E may fit into the lug F as shewn at Figures 4 and 5. To secure the
bar or tube D to a ladies cycle so as to convert it into a gentleman's the lug d'
is fixed to the top. ball head or steering socket lug h¹ by means of the screw
or other pin d which bolt passes through holes formed in the ears or projec-
tions in the socket of the lug h¹. Or. the lug d may be secured to the
lug by other suitable means. The other end of this tube D is fixed to the
seat pillar lug F by means of the seat pillar stem P which passes down the
interior of the socket d and the short tube E into the seat pillar lug F which is
provided with the usual clamping arrangement for holding the seat pillar in
position as clearly shewn at Figure 1. It will readily be seen that by this means
I am enabled to easily and quickly convert a ladies cycle into a gentleman's
having a parallel top tube or rail. The length of the tube E may vary according

page_text: to the height of the tube J and I may also provide the lug d³ with a clamping
arrangement for holding the seat pillar if desired.
At Figure 2 I have shewn a slight modification of my invention. In this case
I form the ball head or steering socket lug h¹ with an extra socket or junction h²
into which the front end of the tube D fits the tube being held therein by the pin
and nut d or by other means. The other end of the tube D is fixed to the seat
pillar lug F in a similar manner as herein before described.
In the modification as shewn at Figure 4 I bulge out the end of the member E
so as to fit over the top of the lug F the said lug being rounded off for this
purpose. Or I may fit the lower end of the member E into the top of the lug F
the member J only passing partly up this lug as shewn at Figure 5. It will thus
be seen that I can take any existing ladies machine and fit my ears or other
parts to it so that I can attach my bar D to it thus making it an exchangeable
or convertible machine.
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:
CLAIMS.
First: The improvements in connection with velocipedes and in the manufac-
ture of the same consisting essentially in attaching or fixing the top tube or
member D removably to the frame of a ladies cycle so as to convert it into a
gentleman's cycle in the particular manner and for the purpose substantially as
herein set forth and as shewn upon the accompanying sheet of drawings.
Second: In convertible cycle the subject of the first claim connecting the front
end of the tube or member Ď to the lug h¹ by a screw or other pin or its equiva-
lent which pin passes through holes formed in ears or projections such as d
and in the socket of the lug h¹ the other end of the said member D being
attached to the seat pillar lug in the manner and for the purpose substantially as
herein set forth and as shewn, at Figures 1, 4, and 5.
Third In cycles which form the subject of the first and second claims forming
the lug h¹ with an extra socket or junction piece 2 in the manner and for the
purpose substantially as herein set forth and as shewn at Figure 3 in regard to
the front end and at all the figures. in regard to the back ends.
Fourth-In cycles forming the rear end of the detachable member D with a
supplemental piece E so that when the said member is attached to the cycle it
assumes a parallel or nearly parallel position in the manner substantially as herein
set forth and as shewn upon the drawings.
