Completa Cassification Loft 17th June 1807 -Accented 17th July 1807
I, THOMAS NEVELL, of No. 19 Lordship Park Stoke Newington, London, N.,
Gentleman, do hereby declare the nature of this invention to be as follows:-
My Invention relates to an improved lock for bicycles, tricycles, or velocipedes,
and has for its object to prevent them being stolen, when they are left unattended.
According to my Invention, I take a "word," or "permutation" lock, consisting
of any suitable number or combination of discs, or diaphragms, with a slot in
each, and marked with letters or figures (or both), and adapt to such lock, a
tapered slotted pin, which is passed through a hole drilled in the head of the
machine, and then slipped into the lock.
The hole in the head may be drilled at any suitable angle (say 45 degrees) to
the frame of the machine so that the pin can be passed through, and the lock
slipped on, outside the frame, after the wheel has been turned to an angle with
the frame. It will thus be seen that by my Invention, the machine can only run
in a circle, and that it will be impossible for any unauthorised person to ride the
machine away in a straight direction, unless he is in possession of the particular
combination of letters, or figures, necessary to open the lock.

I, THOMAS NEVELL of No. 19 Lordship Park, Stoke Newington, London, N.,
Gentleman, 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 an improved lock for bicycles, tricycles, or other
velocipedes, and has for its object to prevent their being stolen, when they are
left unattended.
I will now particularly describe this invention making reference to the
accompanying sheet of drawings in which:
Figure 1 is a broken view in side elevation of the steering post or head of a
velocipede fitted with my invention, and
Figure 2 is a plan view in section on line - of Figure 1.
Throughout both views similar parts are marked with like letters of reference.
A cottar or tapered pin A is slotted or cut away at its smaller end so as to adapt
it to engage with a series of slotted discs or the like B marked with letters or

page_text: figures on their peripheries so as to form a "letter" or "permutation" lock
which can only be disengaged from the pin after a certain combination of letters
or figures have been formed.
To lock the steering of the velocipede and thus prevent it from being ridden,
the pin is first passed through holes formed both in the socket X of the steering
head forming part of the main frame and in the tubular stem X' of the steering
fork, and then the discs B of the "letter" or "permutation" lock are passed on
to the end of the pin forming an enlargement which prevents the pin A from
being withdrawn.
The holes are preferably so formed as not to coincide until the steering wheel
has turned out of line with the frame, preferably in such a position as to form an
angle of 45° as shown. It will thus be seen that by this means, the velocipede
when locked can only run in a circle which effectually prevents it from being
ridden.
Instead of forming the pin A tapered as shown, it may be of the same diameter
throughout in which case its free end is formed with a head.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A lock for bicycles and other velocipedes consisting essentially of a tapered
or headed pin adapted to pass through holes formed in the both parts of the steer-
ing head, the smaller or outer end of the said pin being adapted to receive the
dises of the letter" or "permutation" lock, as and for the purpose set forth.
2. A lock for bicycles, and other velocipedes constructed, arranged and adapted
to operate as and for the purpose set forth.
