Treadles for Bicycles.
DANIEL SPINK, Engineer, 3 Cranham Street Oxford do hereby declare the
nature of this invention to be as follows:-
That of increasing the length of the outer or inner plates of the treadles of
bicycles and also curving the end or ends of such plates, that when they are turned
downwards, they rest on the ground, and thus support the bicycle in an almost
upright position, as shown at B; but such support need not necessarily be formed
of the treadles themselves, but may be attached to such treadles and may be made
of metal or wood or of any other suitable material.
In the drawing one of the treadles is shown at A, while B represents an end
view of a bicycle thus supported, and C is a side view of the above-named treadle.

DANIEL SPINK.
DANIEL SPINK, 3 Cranham Street, Oxford, Engineer, 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 :-
That of making the outer plate or plates of which the treadles of bicycles are
formed, of such a shape that when a treadle is so constructed and turned down-
wards, it keeps the bicycle almost upright, after the rider has dismounted as shown
on Sheet No. 2 where E shows a side view of such treadle turned downwards
and D an end view of the same, where the curved part of the treadle is seen
supporting the bicycle at an angle A, B, C with the ground line B, C.
Sheet No. 1 shews one kind of adaptation of my principle and m is a view
edgewise of the inner plate of treadle and m' a side view of such plate.
to are the usual india rubber pieces or blocks to form the treadle, a section of
which is shown at w' and are kept in their places by the screw-bolts n, n passing
through them, which have their heads countersunk in the before-mentioned plate m,
as shown at t.
The other ends of the bolts n are inserted in the outer piece P and attached to
it by the nuts 9:
r, is the usual distance-piece through which the treadle pin passes, which latter
is attached to the crank in the manner shown at c, View 2 on the same sheet
(Sheet 1) as the preceding details.
The before-mentioned outer piece P may be made of wrought iron, mild steel,
brass, or any other metal or material that may be deemed suitable. P1 is a side
view of the curved outer-piece P, which latter is shown in plan.
View No. 2 on the sanie sheet is that of a treadle similar to No. 1, but has only
one end of the outer-piece curved. P 2 is a plan and P 3 a side view of the same.

page_text: No. 3 on Sheet 3 has both ends of its outer plate curved, but is made of thin
sheet iron or steel.
No. 4, on Sheet 3 also differs from the above in having only one end curved.
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
That of forming the outer treadle plate of bicycles with their end or ends
lengthened and curved, so as to be able to support the bicycle to which they are
attached, in an almost upright position when the rider has dismounted.
Dated this 25th day of June 1894.
