Improvements in Bicycle Locks.
I, AUGUSTUS ROBERT SEWELL, residing at No. 162 Spruce Street, Detroit, in
the County of Wayne, and State of Michigan, United States of America, Clerk,
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:-
3-41
This invention relates to locks for bicycles and similar vehicles, and the object
thereof is to provide an improved device of this class by means of which both
wheels of the bicycle may be securely locked whenever desired; and with this and
other objects in view; the invention consists in the construction, combination and
arrangement of parts hereinafter described and claimed.
The invention is fully disclosed in the following specification, of, which the
accompanying drawing forms a part, in which';
Fig. 1, is a side view of a portion of a bicycle showing the application of my
improved lock;
Fig. 2, a side view of the lock detached, and on an enlarged scale;
Fig. 3, a similar view showing "the manner of folding the separate parts of the
lock together;
t.
Figs. 4, and 5, are plan views of separate locking bars which form a part of the
lock, said bars being detached from the casing of the lock in connection with which
they are used; and,
:
Fig. 6, a section on the line 6, 6, of Fig. 3.
In the drawing forming part of this specification, the separate parts of my
improvement are designated by the same numerals of reference in each of the
views, and in said drawing I have shown at 7, a part of the drive wheel of a
bicycle or similar vehicle, and at 7°, a part of the guide wheel, and between the
wheels 7, and 7, are shown the support 8, of 'the pedal shaft, and the pedal
cranks 9, connected with said" shaft, and in the practice of my invention I provide
a lock which comprises a box or casing 10, which is preferably rectangular in form,
and through which are passed two locking bars '11, and 12, each of which is
provided with a hinged section 13, said hinged sections being connected, with said
locking bars at 11, and 12 by means of hinges 14 as clearly shown in Fig. 1.
The locking bars 11, and 12, are provided at the 'ends thereof opposite the
hinge 14, with shoulders or projections 16, and 'said ends project through the box
or casing 10, in opposite directions, and the locking bar 11, adjacent to the shoulder
or projection 16, is round for a' portion of its length as shown at 17, whereby it
may be turned in the casing 10, and the locking bar 12, is also provided with a
round portion 18, for a similar purpose.
The box or casing 10, is provided with a key hole 19, and mounted therein, is a
locking device of any desired form or construction, part of which is shown in
dotted lines at 20, and said locking device is adapted to be operated by a key, and
is also adapted to operate in connection with ratchet teeth 21, formed on the bottom
of the locking bar 11.
The hinged section 13, of the locking bar 11, is provided with a hook 22, which
is adapted to engage with the rim of one of the wheels, as shown in Fig. 1, and the
hinged section 13, of the locking bar 12, is provided' with a corresponding hook 23,

page_text: which is adapted to engage with the tire of the other wheel, and the holes or
openings in the box or casing 10, through which the bars 11, and 12, are passed,
are rectangular in form as shown at 24, in Fig. 6, and the main portions of said
bars are also rectangular in cross section, and the operation will be readily
understood from the foregoing. description when taken in connection with the
accompanying drawing, and the following statement thereof.
When the locking bars are in position for locking the vehicle, the ratchet teeth
on the bar 11, projects downwardly, and the hooks 22, and 23, project transversely
of the rims of the wheels, and the hinged section of the said bars are swung into
line with the main portions thereof, and the bar 12, is passed through the casing
until the lugs or projections 16, strike the side thereof, after which the bar 11, is
forced into the casing, in the opposite direction as far as it will go, the hooks 22,
and 23, being connected with the tires of the wheels, and the lock within the box
or casing 10, is operated, to hold. the bars in this position, and in this position of
the lock the wheels of the vehicle will be securely held and cannot be operated,
and in order to unlock the device, the key must be inserted into the box or casing.
Any suitable form of lock may be placed in the box or casing, and my invention
is not limited thereto, and it will be apparent that changes in, and modifications of
the construction herein described, may be made without departing from the spirit
of my invention, or sacrificing its advantages.
In order to fold the separate parts of the lock, so as to put the same in the
pocket, the locking bars 11, and 12, are adjusted in the box or casing 10, so that
they may be turned on their cylindrical portions 17, and 18, and when this is done,
the hinged sections 13, may be folded parallel or adjacent to the main portions 11,.
and 12, of the locking bars, and in this position of the parts, the hooks 22, and 23,
will be in the same plane as said bars, and said box or casing.
This position of the parts, of the lock is shown in Fig. 3, and the device when
thus folded, may be conveniently carried in the pocket as will be readily
understood.
Having fully 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 similar vehicles, the same comprising a box or casing,
locking bars which are longitudinally movable therein, the opposite ends of said
bars being provided with a hinged section, each of which is provided with a hook,
and said bars being adapted to be adjusted in said box or casing, and to be locked
in the desired position therein, substantially as shown and described.
2. A lock for bicycles and similar vehicles, comprising a box or casing, two
longitudinally movable and parallel locking bars mounted therein, one of which is
provided with ratchet teeth, said bars being provided at their opposite ends with a
hinged section, each of which is provided with a hook, and said box or casing being
also provided with a key operated lock, which is adapted to operate in connection
with the ratchet teeth on one of said bars, substantially as shown and described.
3. A lock for bicycles and similar vehicles, comprising a box or casing, two
longitudinally movable and parallel locking bars mounted therein, one of which is
provided with ratchet teeth, said bars being provided, at their opposite ends with
a hinged section, each of which is provided with a hook, and said box or casing
being also provided with a key operated lock, which is adapted to operate in
connection, with the ratchet teeth on one of said bars, said bars being also
cylindrical in form for a portion of their lengths, and each being provided at the
end thereof, opposite the hinged extension with a lug or projection substantially as
shown and described.
4. The herein described lock for bicycles and similar vehicles, the same.consisting
of a rectangular box or casing in which are mounted two longitudinally movable
parallel bars, the main portions of which are angular in cross section, and the
openings in said box or casing through which said bars. are passed being, also
angular in form, said' bars being provided at their opposite ends with a hinged

page_text: extension each of which is provided with a hook said bars being also provided with
a cylindrical portion, and with lugs or projections at the ends thereof opposite the
hinged extension substantially as shown and described.
