CORNELIUS HENRY ROBBINS Stafford Street Wolverhampton in the County
of Stafford Lock Manufacturer do hereby declare the nature of this invention to
be as follows:-
An improved lock for cycles and other purposes. By moving a knob or device

The lock is made with a semi-circle front and is fastened on the ball head tube
by four steel screws and a steel dowel into the bottom bracket tube, it contains a
steel bolt with a squar body and round or flat head. A rider having alighted off
his safety cycle has only to slide a small device or knob up turn his front wheel to

bolt shooting itself into the front fork tube and cannot be forced back without.

I, CORNELIUS HENRY ROBBINS Lock Manufacturer 61 Stafford Street
Wolverhampton in the County of Stafford 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 :-
The lock is of rhomboidial contour, having neck in upper end at G for device E
to work in, with a semicircular front to fit to ball head tube of cycle, and is fixed
underneath top ball head lug or on the top of bottom ball head lug by 4 steel
screws and a steel dowel at H. There are two runners at CC having slots and
pin hole through them, in which the bolt A and spiral spring B work. The bolt A
has three slots and pin hole through it. There is also the short bolt D with long
projection and flange which goes through slot 1 in bolt A, and the device E with
pin and spiral spring at F. The lock can have either square, round, flat, or oval
bolt and be made with one, two, three, four or five levers, and have piped or
pinned key. The lock can also be made with a knob slide fitted on top or bottom
plate of lock to be used instead of the device and pin if preferred in which case
slots 2 and 3 in bolt A would be requred.
A rider having alighted from his machine and turned the handle bar to the
right or left, by lifting the device E or slide knob with pin attached, liberates the
bolt A, which is shot out by the spiral spring B into the fork top inner ball head
tube or steering gear, and cannot be forced back without inserting the proper key.
The machine is therefore unriderable. No key is required to lock the lock, and

page_text: the key is only inserted and turned half way round to draw back the bolt, in which
operation the steel pin in device is forced through the bolt A and the two
runners CC by the spiral spring F attached to device; and the bolt is thus kept
secure in that position, while the machine is being used.
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 :
1st. The bolt A with three slots and pin hole through.
2nd. The two runners C C with slots and pin hole through them.
3rd. The device E and pin and its neck at G in upper end of lock.
4th. The short bolt D with long projection and flange.
5th. The combination of the construction and mechanism of the lock.
