Improvements in Bicycle Locks.
I, SAMUEL HUGH PATTERSON, of 661, 6th Avenue, in the City, County and
State of New York, United States of America, Agent, 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 locks for bicycle wheels and the object thereof is to
produce a padlock or a lock of similar character, which may be applied to the
sprocket wheel of a bicycle, and to the drive chain thereon, whenever it is desired
to lock the machine.
The invention is fully disclosed in the following Specification, of which the
accompanying drawing forms a part, in which :-
Fig. 1, is a side elevation of a sprocket wheel and its supports, showing also the
drive chain and my improved pad lock applied thereto; and,
Fig. 2, a section on the line 2, 2, of Fig. 1.
Referring to Fig. 1, of the drawing A, designates the sprocket wheel of a bicycle,
on which is mounted the drive chain B, and that portion of the frame of the
bicycle which supports the sprocket wheel, as shown at C, D, and E.
In the practice of my invention, I provide a lock of the general form and
character, of an ordinary pad lock as shown at F, the yoke or bale G, of which
however is formed so as to conform to the shape of the rim of the sprocket wheel
in cross section, as shown at H, aud K, in Fig. 2, and the body of the lock is
provided with a lug or extension L, which projects inward as shown in said figure,
and when the lock is applied to the sprocket wheel, as shown, the lug or
projection I, extends into the chain B, or between the links, thereof, as shown in
Fig. 2, so as to prevent the revolution, of the chain upon the wheel, and it will
thus be seen that when thus applied my improved lock constitutes a simple and
effective device for accomplishing the object for which it is intended.
My improved lock for bicycles, is not limited to any particular form or con-
struction of the locking mechanism, the only object being to produce a pad lock of
such form and construction, that when applied to the sprocket wheel, and the drive
chain of a bicycle, the parts will be so locked together as to prevent the operation
of the machine.
Having fully described my invention, I claim and desire to secure by Letters
Patent :-
1. The combination with a sprocket wheel and the drive chain of a bicycle, of a
pad lock the yoke or bale of which encloses the rim of the wheel, and the chain,
substantially as shown and described.
2. The combination with a sprocket wheel of a bicycle and the drive chain, of a
pad lock the yoke or bale of which when applied to the wheel, encloses the rim of
the wheel and the chain, said yoke or bale being so formed as to conform to the
shape of the rim of the wheel, in cross section and said pad lock being provided
with a lug or projection, which extends into or between the links of the chain,
substantially as shown and described.
3. A lock for bicycles consisting of a pad lock, the yoke or bale of which is
adapted to be connected with the rim of the wheel, and the chain, so as to enclose
the same and prevent the operation of the chain on the wheel, substantially as
shown and described.

chain, substantially as shown and described.
