1, CHRISTOPHER GRANT, of St. Mary's, Bedford, in the County of Bedford, Engineer,
do hereby declare the nature of this invention to be as follows :-
My invention relates to rear-driving safety bicycles.
In rear-driving safety bicycles as ordinarily constructed the backbone or some other
part or parts of the machine is or are at such a height from the pedals that a female
cannot in ordinary dress conveniently use them.
The object of my present invention is to construct rear-driving bicycles in such a
manner that they can be ridden by females in ordinary dress, and to this end it com-
prises the improvements hereinafter described.
According to my present invention the backbone proper is kept at or about on a
level with a horizontal line through the centre of the back wheel (so as to keep it as
low as possible) except near the front wheel, where it curves upwardly and is jointed
to the front wheel standard. The seat standard is secured to the backbone close to the
back wheel and the treadle shaft is placed immediately beneath this standard.
No stay is placed between the seat standard and the steering standard and the
portion of the backbone between the latter and the seat standard must be of
sufficient length to afford ample room for a lady to enter between the same.

page_text: I, CHRISTOPHER GRANT, of St. Mary's, Bedford, in the County of Bedford, 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:
My invention relates to rear-driving safety bicycles.
In a rear-driving safety bicycle as ordinarily constructed the backbone or some
other part or parts of the machine is or are at such a height from the pedals that a
female cannot in ordinary dress conveniently use it.
The object of my present invention is to construct rear-driving bicycles in such a
manner that they can be ridden by females in ordinary dress, and to this end it com-
prises the improvements hereinafter described.
In the accompanying drawing I show in side elevation a bicycle constructed accord-
ing to my invention.
a is the front steering wheel, b is the driving wheel, and c is the treadle axle from
which motion is communicated to the driving wheel.
d is the backbone the main part of which is kept at or about on a level with a hori-
zontal line through the centre of the driving wheel b or somewhat below the same
(so as to keep it as low as possible) and 61 is the front part which, near the front
wheel, curves upwardly and is jointed to the front wheel standard at e.
fis the seat standard which is secured to the backbone close to the back wheel, the
treadle shaft being placed immediately beneath this standard. From the base of the
seat standard the backbone extends forward before it curves upwardly to the steering
standard so as to afford ample room for a lady to enter between the same.
stay is placed between the seat and steering standards so that the space in front of
the seat is free.
No
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. The improvement in rear-driving safety bicycles which consists in placing the
main portion of the back bone at or below a horizontal line extending through the
axis of the driving wheel, and in extending the said back bone forward from the base
of the seat standard substantially as, and for the purpose, described.
2. The improved rear driving safety bicycle constructed and arranged substantially
as herein before described and illustrated in the accompanying drawing, for the purpose
specified.
