Improvements in or relating to Bicycles.
I, STELIANOS SINOPYSKY, of 36, Argyle Road, Southampton, in the County of
Hants, Ship's Steward, do hereby declare the nature of this invention to be as
follows:-
My invention relates to bicycles.
The main object of my said invention is so to construct a bicycle that it can be
easily adapted for use either as a gentleman's or lady's machine.
According to my invention I construct the frame of a bicycle in the diagonal
form as made for ladies, (save with the additions hereinafter described) that is
without a fixed connecting top bar or tube between the seat pillar tube and steering
pillar tube heads, but I provide such a connecting top bar or tube as a separate
portable part that can be fitted and fixed at will between the head of the seat
pillar tube and steering pillar tube head when it is desired, and the said connecting
bar or tube can as readily be disconnected at will and re-adjusted and fixed in
another position when desired, so as to re-adapt the machine for a lady's use.
In carrying out the construction of a bicycle according to my improvements so
as to attain the above object I provide that there shall be formed upon, or attached
to the fore side of the head of seat pillar tube a short length of horizontal tube or
rod, and upon the back of the head of steering pillar tube a similar short piece of
horizontal tube or rod.
If these fittings are made of tube a short plug will be inserted and fixed in the
open end of same, and in the solid end so formed a vertical dovetail shaped recess
is made in depth about one half of the diameter of the tube or rod, as the case
may be.
I prefer to make the connecting bar of tube, in both ends of which I fit and
fix a plug the projecting end of same is shaped so as to fit in the dovetailed recess
in the aforesaid fittings provided on the seat pillar tube and steering pillar tube
heads respectively.
When the bicycle is adjusted for a gentleman's use the connecting tube will be
fitted between the seat pillar tube and steering pillar tube heads, the dovetailed
ends of the connecting tube being then in engagement with the correspondingly
shaped recess in the fittings aforesaid. For the purpose of further securing the
connecting tube in the connected position I provide internally screw threaded
collars or nuts which are arranged to screw over the joints thus securing the
connecting tube in place.
I further provide on the machine similarly shaped projecting fittings, to those
above described, one at the underside of the aforesaid fitting on the back of steer-
ing pillar tube head, and another at the lower front part of the seat pillar tube,
just above the fixed diagonal stay, these fittings are placed so as to take the con-
necting tube in similar manner as when same is fitted horizontally at the top of
the machine, but the connecting tube will now lie in a diagonal direction forming
a supplemental diagonal stay, thus adapting the machine for lady riders.

page_text: The unoccupied open ends of the fittings that take the connecting tube,—as
the case may be according to the position in which the latter is fitted,-will be
covered by suitable blank screw caps.
Improvements in or relating to Bicycles.
I, STELIANOS SINOPYSKY, of 36, Argyle Road, Southampton, in the County of
Hants, Ship's Steward, 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 bicycles.
The main object of my said invention is so to construct a bicycle that it can be
easily adapted for use either as a gentleman's or lady's machine.
In the accompanying drawings I have shewn what I consider to be the best
means of carrying out my invention, in which :-
Fig. 1 is a central sectional elevation shewing part of the framework of a
bicycle constructed according to my invention.
Fig. 2 a plan partly in section taken on the line a, a, (Fig. 3).
Fig. 3, a general outside view in elevation of a bicycle constructed according to
my invention.
Fig. 4 a complete cross sectional view taken on the lines b, b.
Like letters indicate corresponding parts throughout the drawings.
In making a bicycle according to my invention so as to attain the aforesaid
object I provide that there shall be formed upon, or attached to the frame of the
bicycle short lengths of tube, or rod at A, B, C, and D; respectively, forming lugs.
If these fittings are made of tube a short plug E, E, and E¹, E¹ will be inserted in
each of same and in the solid end so formed a vertical dovetail shaped recess F,
is made, in depth about one half of the diameter of the plug.
I prefer to make the connecting bar G of tube, in both ends of which I fit and
fix a plug H, H, the projecting ends of same are shaped so as to fit into the dove-
tailed recesses F, F.
When the bicycle is adjusted for a gentleman's use the connecting tube G will
be fitted between the seat pillar tube and steering pillar tube heads, as shewn in
full lines, in Figs. 1, 2, and 3, the dovetailed ends of the connecting tube G being
then in engagement with the correspondingly shaped recesses in the fittings E, E,
and for the purpose of securing the tube G in place in the connected position I
provide internally screw threaded collars or nuts J, J, which are arranged to screw
over the joints thus securing the connecting tube in place. When the bicycle is
adjusted for a lady rider the connecting tube G will be disconnected from the
aforesaid position and adjusted in the diagonal position as shewn in dotted lines
Figs. 1, and 3, in similar manner as hereinbefore described when adapting the
machine for a gentleman's use.
When the connecting tube G is in position adapting the machine for a lady's
use it will form a supplemental diagonal stay.
The unoccupied ends of the fittings that take the connecting tube G,-as the
case may be according to the position in which the latter is fitted,-will be covered
by suitable interchangeable blank screw caps K, K.

page_text: It will be seen that the connecting tube of a bicycle, made according to my
invention, is interchangeable from the horizontal to the diagonal position accord-
ing to whether the machine is required to be ridden by a lady or gentleman, and
that only one connecting tube G is required which is always fixed in one of the
two positions as desired.
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:-
1st. The improved bicycle consisting of the parts all constructed and combined
substantially as described with reference to the accompanying drawings and
arranged to operate as and for the purposes above specified.
2nd. The construction of a bicycle with an interchangeable connecting bar or
tube G, and other devices substantially as herein described for the purposes
specified.
3rd. The herein described method of, and means for, connecting and securing
the connecting bar or tube G in the two different positions for the purposes
specified.
4th. The combination in a bicycle frame of an interchangeable connecting
bar G, adapted to serve as a horizontal or diagonal stay, substantially as herein
described for the purposes specified.
