PROVISIONAL SPECIFICATION.
A Contrivance for the Purpose of Rendering a Cycle (of the Safety
Type) suitable for either Lady or Gentleman.
I, FELIX JOAQUIM DE ANDRADE of 26 Chetwynd Street, St. Michael's
Hamlet, Liverpool, in the County of Lancaster, Clerk, do hereby declare the
nature of this invention to be as follows:-
On the hend & apex of the triangle formed by the frame, is attached a solid
circular bracket which is slotted with a "V" shaped slot. A tube (circular in
section) is fitted at both ends with a solid "V" shaped feather which are attached
to it by means of a screwed thread-the round neck of the feather being screwed
to go inside the tube-these feathers fit into the aforesaid slots, and, when the
machine is adapted for a gentleman forms the top tube-but when the machine is
required for a lady's use this tube is removed & placed in two other slotted
brackets-one placed on the upper portion of the head & the other just above the
driving crank on the back bone-to secure the feathers in the slots, small holes are
drilled through the feathers & cheeks of the slots & secured with a bolt & nut.
Dated this 29th day of July 1896.

A Contrivance for the Purpose of Rendering a Cycle (of the Safety
Type) suitable for either Lady or Gentleman.
I, FELIX JOAQUIM DE ANDRADE, of 26, Chetwynd Street, St. Michael's
Hamlet, Liverpool, Clerk, 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 relates to means of adapting the ordinary "diamond" frame of
bicycles, and other velocipede frames constructed on the same or an equivalent
principle, to the service of either a lady or gentleman, and consists in constituting
the upper horizontal member of such frame removable and capable of occupying
two distinct positions in the frame.
In the accompanying drawing,
Figure 1 shews the application of my invention to a diamond frame bicycle, and
Figure 2 its application to a tandem bicycle.
Figure 3 is a detail view of the removable member of the frame and its
fittings.
I attach the upper horizontal member A of a diamond frame to its adjacent
members B and C in the manner shewn in detail in Figure 3, namely by the
bevelled tongue pieces a carried by the member A, which ship between two
internally bevelled cheeks 6 formed in each of the four couplings D, D, D¹, D',
carried by the members B and C. The tongues a have each an abutment collar c
and a stem d, which latter screws into the tubular member A. The tongues a may
be secured in the cheeks b by a split. pin or a small bolt and nut, which passes

page_text: through the apertures e. The screw threading of the stems d is preferably right
and left handed at opposite ends of the member A, so that by turning the latter the
frame may be drawn together. In other cases the member A and stems d may be
brazed together.
Figure 2 shews the application of my invention to a tandem bicycle,
and as the parts above described are only multiplied, it needs no further
description.
To adapt the frames shewn in Figures 1 and 2 to ladies' use, the member A
is unshipped from its upper position (shewn in full lines) by removing the split
pins or bolts from the cheeks b. The member A and its tongues a are then lifted
out of the upper couplings D, D, and placed in the lower couplings D', D', thus
assuming the position shewn in dotted lines in each figure, where they are secured
by reinserting the split pins or bolts in the cheeks 6 of such lower couplings and, if
necessary, revolving the member A upon its right and left hand threaded tongue
stems d.
In the case of the tandem bicycle, one member A may remain in its upward
position and the other member A may be removed to its lower position, when the
bicycle is ridden by a lady and gentleman.
It will be seen that my invention provides for the adaptation of a bicycle to
either a lady or a gentleman's use, in a simple manner, and at the same time
utilising all the members of the frame for the purpose of strengthening the
frame.
Although I have described the application of this invention to single and
tandem bicycle frames only, it must be understood that the invention is equally
applicable to the frames of tricycles and other velocipedes constructed on the
diamond or equivalent principle.
I am aware that it has heretofore been proposed to constitute the upper member
of a diamond frame removable for ladies' use; but where this has been done the
said member is discarded and the frame is consequently weakened, and it has not,
so far as I am aware, been proposed to remove such member to another position in
the frame so as to utilize it for strengthening the latter when used by ladies, as is
done in my present invention.
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 :-
1. A "diamond" or equivalent velocipede frame comprising a removable
member A, into the ends of which are screwed, with right and left hand threads,
the stems d of tongue pieces a, which latter may be entered at will into corre
sponding cheeks 6 formed on each of two pairs of brackets D D and D' D',
mounted at different altitudes on said frame, and be secured therein by pins or
bolts, whereby said removable member may, when occupying the upper pair of
cheeks b, form the upper horizontal member of said frame, for gentlemen's use,
or may, when occupying the lower pair of cheeks b, strengthen the frame for
ladies' use, as hereinabove described and illustrated in the annexed drawing.
2. Constituting the upper member A of a diamond or equivalently shaped frame
of a velocipede, capable of transposition from its position as the upper horizontal
member of said frame to a lower position parallel or approximately parallel with
the lower inclined member of said frame, substantially as and for the purpose
herein described and illustrated.
