PROVISIONAL SPECIFICATION.
Improvements in Safety Bicycles.
I LOUIS WILLIAM JELF-PETIT of 77 Colmore Row Birmingham, Barrister at
Law in the County of Warwick do hereby declare the nature of my said invention
to be as follows
My invention has for its object improvements in safety bicycles by means of
which such machines may be made to stand independently of any separate support
such as a wall, the curb stone or other object and this I accomplish in a most simple
cheap and effective manner.
In carrying my invention into effect I attach a pendant support to or across the
outside end of one or both of the pedals of the machine by means of a shaped
plate to fit the top of the pedal and pins with countersunk heads passing between
the bars of the pedals into the cross plate of the said support where they are
secured by nuts or their equivalent. To this support I hinge or pivot a prop or
crutch which turns down or hangs under the pedal or pedals so that the bottom of
the said crutch when down rests on the ground and thus supports the machine in a
vertical or practically vertical position. Pointed projections are formed upon the
bottom of the crutch for entering the ground. The crutch hinged and arranged to
turn up over the end of the treadle until the sides of the crutch are parallel or
nearly parallel with the rubber or other tread of the pedal. A slight incision may
be made in the rubber to receive the bar which connects the sides of the crutch
together so that there is no projection above the tread of the rubber.
A shoulder may be formed upon the crutch so that when in position for supporting
the machine it rests against a pin or other projection upon the pendant support for
the purpose of preventing the possibility of the crutch turning under on its own
hinge when the weight of the machine is brought to bear upon it.
It will be understood that while the machine is in use it is impossible for the
crutch to accidently fall down as the foot keeps it in the required position.
I do not confine myself to the exact mode of carrying out my improvement as it
will be evident that a number of modes may be used for mounting a crutch to the
end of the pedal.

COMPLETE SPECIFICATION.
Improvements in Safety Bicycles.
I, LOUIS WILLIAM JELF-PETIT of 77 Colmore Row Birmingham in the County
of Warwick Barrister at Law do hereby declare 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 statement :-
My invention has for its object improvements in safety bicycles by means of
which such machines may be made to stand independently of any separate support
such as a wall, the curb stone, or other object and this I accomplish in a most
simple cheap, and effective manner.
In carrying my invention into effect I attach a pendant support to or across the
outside of one or both of the pedals of the machine by means of a shaped plate to
fit the top of the pedal and the pins with counter-sunk heads passing between the
bars of the pedals into the cross plate of the said support where they are secured

page_text: by nuts or their equivalents. To this support I hinge or pivot a prop or crutch
which turns down or hangs under the pedal or pedals so that the bottom of the said
crutch when down rests on the ground and thus supports the machine in a vertical
or practically vertical position. Pointed projections are formed upon the bottom
of the crutch for entering the ground. The crutch is hinged or arranged to turn
up over the end of the treadle until the sides of the crutch are parallel or nearly
parallel with the rubber or other tread of the pedal. A slight incision may be made
in the rubber to receive the bar which connects the sides of the crutch together so
that there is no projection above the tread of the rubber.
A shoulder may be formed upon the crutch so that when in position for supporting
the machine it rests against a pin or other projection upon the pendant support for
the purpose of preventing the possibility of the crutch turning under on its own
hinge when the weight of the machine is brought to bear upon it.
It will be understood that while the machine is in use it is impossible for the
crutch to accidentally fall down as the foot keeps it in the required position.
I do not confine myself to this exact mode of carrying out my improvement as
it will be evident that a number of equivalent devices may be used for mounting a
crutch to the end of the pedal.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a double sized sheet of drawings upon which
I have illustrated three modes of applying the same to an ordinary treadle and which
will be quite sufficient to enable others to adapt the invention to other forms or
modifications as may be required in practice.
Figure 1., is a side elevation of my invention applied to the pedal B of the
crank A of any ordinary safety bicycle. The invention is shewn in its closed up
condition as it would be when the machine is running.
Figure 2, is a plan of the invention in the exact position as shewn by Figure 1.
Figure 3., is a broken off prospective view of a portion of the pedal B showing
one of the modes of fixing the invention by means of the angle plates E.
Figure 4, is a side elevation of the invention similar to Figure 1 except the
pendant part or crutch K is here turned down as it would be when the machine is
at rest.
Figure 5, is an end elevation of the invention in the same position as seen in the
previous Figure 4.
Figure 6., is a sectional elevation looking to the right on line C-D Figure 7
showing a slightly different mode of fixing to that of the previous figures and
easily adaptable to any existing machines now running without any alteration
thereto.
Figure 7., is a side view of the modification as seen at Figure 6.
Figure 8., is a cross sectional elevation on line U-V of Figure 9 looking to the
right and shewing another slight modification in the mode of fixing the invention.
Figure 9., is a side sectional elevation on line W-X of Figure 8 which allows
the U-fastening S to be more distinctly seen.
In Figures 1, 2, 3, 4, & 5 I have shown my improvements in safety bicycles
as they would generally be applied to such machines when they are at first built
and this modification I will explain first as follows:-The two angle plates E as
seen in all the first five figures upon the drawing, but most clearly at Figure 3, are
bent round with the rings el and holes through which the pedal pins pass thus
securing them one on each side to the pedals B. To these angle plates Ę I hinge
or pivot my pendant support or crutch K at es and k¹ in such a manner that when
it is turned down the shoulder A bears against the edge of E and prevents the
crutch from turning too far as seen at Figures 4 & 5. At Figure 5 the construction
of the crutch is clearly seen where the two sides K are secured at the upper part
by the pivot bar the angle pieces E are riveted or otherwise secured at the ends
over the washers while the lower ends of K are kept firm by the cross plate k³
secured to the side plates K by the tongues 7. The edges of plates Kinay be
Figures 1 & 4 or they may be plain as seen at Figure 7. The
serrated as seen at k

page_text: points are useful to hold in the ground when turned down as at Figure 4 but the
ends of the sides K may answer the same purpose. In Figures 1, 2 & 3, the
crutch K is shewn turned up and folded over and entirely out of the way which is
their normal position when the machine is running.
The crutch may be provided with slots P as shewn by dotted lines in Figure 4
in which case the bar would be secured in the slots by nuts so that the crutch
may be raised or lowered to suit the height of various pedals or adjustment may be
made at the same time as the length of the pedal is altered.
In Figures 6 & 7 the pedal rubbers B are shown round & the crutch K is hinged
to a plate N by the two ears n¹. This plate N is secured to the pedal by two
screws n which pass through it and also through another plate n' which securely
binds the whole together. It will be understood how easily this modification may
be applied to any machine now in use.
A similar modification to the last is shewn by Figures 8 & 9 where the plate N is
attached to the pedal by a U-clip S which has two screwed ends s¹ which pass
through the plate N the curved portion of the U-plate S fitting over the centre
strut 6 of the pedal.
I have shown these three modes of applying my invention as simple illustrations
but do not confine myself to these or to the particular configuration of the crutch K
or other parts as they may evidently be varied to a great extent without departing
from the principle of the invention. It will also be evident that the invention
may be applied to either one or both of such pedals or to even more if desired as
in such machines for instance as tandems.
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 :-
The improvements in safety bicycles of a crutch or crutches such as K attached
thereto substantially as and for the purpose herein set forth and as shewn upon
the drawings.
