page_text: Date of Application, 30th Dec., 1895
Complete Specification Left, 24th Apr., 1896-Accepted, 25th July, 1896
I, SAMUEL HUGH PATTERSON, resident of 245 Broadway, New York, County of
New York, and State of New York, United States of America, Commercial Traveller,
do hereby declare the nature of this invention to be as follows:-
This invention relates to locks for bicycle wheels, and the object thereof, is to
produce a pad lock or lock of similar character which may be applied to the sprocket
wheel of a bicycle, and to the drive chain thereon, when it is desired to lock the
machine.
+
The invention is fully disclosed in the following specification.
In the practice of my invention, I provide a lock of the general form and character,
of any ordinary pad lock, but formed so as to conform to the shape of the rim of the
sprocket wheel in cross section, and the body of the lock is provided with a lug or
extension, which projects inward, and when the lock is applied to the sprocket wheel,
the lug or projection extends into the chain or between the links thereof, 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 construction
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.

Improvements in Bicycle Locks.
I, SAMUEL HUGH PATTERSON, a citizen of the United States, residing at
661 Sixth Avenue, of the City, County, and State of New York, U.S.A., late of
245 Broadway, New York, U.S.A., 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 pad lock or 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 drawings form a part, in which ;-
Fig. 1, is a side elevation of a sprocket wheel and its support, 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.

page_text: 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, and K, in Fig. 2, and the body of the lock is
provided with a lug or extension L, which projects inward as also shown in said
figure, and when the lock is applied to the sprocket wheel, as shown, the lug or
projection 1, 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 cbject for which it is intended.
con-
My improved lock for bicycles, is not limited to any particular form or
struction of the locking mechanism, the only object being to produce a pad lock
of such form or 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 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 1
claim is
1. In combination with a sprocket wheel and drive chain of a bicycle, of a pad
lock, consisting of a main or body portion adapted to engage the chain and the
yoke to engage one of the sprockets or lugs on said wheel whereby said wheel and
chain are clamped together, substantially as described.
2. In combination with a sprocket, wheel and a drive chain of a bicycle, of a
pad lock, consisting of a main or body portion, having an extension adapted to
engage the chain and the yoke having the same configuration or form as the
projections on the wheel, whereby when the lock is fastened the chain and the
wheel are clamped together, substantially as described.
