Improvements in Bicycle Locking Devices.
1, JOHN REEVE VAN DERVEER, of 34 Watts Street, New York City, N.Y. in
the United States of America Manufacturer, 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 especially to devices employed for securing the wheels of
bicycles against movement when the machine is left in an exposed or unguarded
position, and has for its object the provision of a simple, cheap and effective device
adapted and arranged to secure both of the wheels against rotation.
To attain the desired end, iny invention consists essentially in a body provided
at each extremity with separate hooks, adapted and arranged to engage with the
rims of both wheels of a bicycle, or with the front wheel and the driving sprocket,
and be locked in such position, preventing the possible rotation of both of the
wheels.
In the accompanying drawing forming a part hereof,
Fig. 1 is a plan view of my locking device with the parts closed, as when
in use.
Fig. 2 is a plan view showing the grasping hooks as opened out.
Fig. 3 is a plan view showing the device as folded for carrying.
Like numerals of reference indicate corresponding parts.
The parts of the device are preferably stamped or struck up of sheet metal.
1 are shanks, pivoted together at 2. 3 are hooks pivoted to the shanks 1 at 4,
and to each other at 5. At 6 the shanks 1 are slotted, and in said slot play
pivots, 7 which engage with hooks, 8, pivoted together at 9. This slot permits
a variation of the length of the locking device in accordance with the space
beneath the wheels to be locked.
10 is a lock, preferably mounted upon one of the shanks, 1, although any form
of lock, such as a padlock may be substituted therefor. 11 is the key hole of the
lock, the bolt being arranged to engage with a perforation or depression 12 in the
opposite shank 1 when the parts are in place, as in Fig. 1.
When not in use, the device is folded up as in Fig. 3, and may be carried in the
tool bag or pocket. When it is desired to secure a bicycle, the parts are unfolded
and extended, as in Fig. 2, and then the hooks 3 and 8 are clasped around the
front wheel and sprocket, holding both wheels against movement and the shanks
locked together.
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. A bicycle locking device in which is comprised a body provided at each
extremity with separable hooks adapted and arranged to engage with the front and
rear wheels or with the sprocket and front wheel of a bicycle, and be secured
against opening.
2. In a bicycle locking device, a body provided at each extremity with separable
grasping devices, and means for securing the grasping devices in a closed position.
3. A bicycle locking device in which is comprised folding body, the parts
whereof, are connected together by pivots; grasping hooks located at each

page_text: extremity of the body, and a lock arranged to hold the parts in place, when
closed.
