PROVISIONAL SPECIFICATION.
Improvements in Locking Apparatus connected with the Steering
Gea of Bicycles and other Velocipedes.
We, ROBERT EASTHAM of 42, Turpin Green Lane, Leyland, in the County of
Lancaster, Engineer, and GEORGE HAWORTH of 6 Ashton Terrace, Preston in
same county, Hose Pipe Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention has for its object to place difficulties in the way of bicycle thieves
by locking the front or steering wheel in such a position that the bicycle or other
velocipede cannot easily be moved unless it be lifted off the ground and carried bodily.
To this end we affix to the socket of the front fork locking apparatus having a
spring bolt so arranged that when the front wheel is brought round to a position
preferably at right angles to the rear wheel the outer end of the bolt slips into a
hole in the fork head thus securely holding or locking the said front wheel in its
crosswise position. A suitable key is employed to fetch the spring bolt out of the
hole when the apparatus is to be released and the front wheel moved back again to
its normal position. The lock may conveniently be secured to the socket by being
formed in one piece with one of a pair of metal clips which may be drawn together
and fastened to the outside of the socket by means of screws. The outer end of
the bolt passes through a projecting part or nipple which fits within a hole in the
socket additional means being thus provided for preventing the locking apparatus
being forced out of place on the socket. It is obviously desirable that with
apparatus as above described the locks and keys should all be different that is to
say that no key should fit more than one lock.

Improvements in Locking Apparatus connected with the Steering
Gear of Bicycles and other Velocipedes.
We,
ROBERT EASTHAM, of 42 Turpin Green Lane, Leyland, in the County of
Lancaster, Engineer, and GEORGE HAWORTH, of 6 Ashton Terrace, Preston, in
the same county, Hose Pipe 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 :-
This invention has for its object to place difficulties in the way of bicycle thieves
by locking the front or steering wheel in such a position that the bicycle or other
velocipede cannot easily be moved unless it be lifted off the ground and carried bodily.
To this end we affix to the socket of the front fork locking apparatus having a
spring bolt so arranged that when the front wheel is brought round to a position
preferably at right angles to the rear wheel the outer end of the bolt slips into
a hole in the fork head thus securely holding or locking the said front wheel in
its crosswise position. A suitable key is employed to fetch the spring bolt out of
the hole when the apparatus is to be released and the front wheel moved back

page_text: again to its normal position. The lock may conveniently be secured to the socket
by being formed in one piece with one of a pair of metal clips which may be
drawn together and fastened to the outside of the socket by means of screws.
The outer end of the bolt passes through a projecting part or nipple which fits
within a hole in the socket additional means being thus provided for preventing
the locking apparatus being forced out of place on the socket. It is obviously
desirable that with apparatus as above described the locks and keys should all
he different that is to say that no key should fit more than one lock.
In the accompanying drawings,
Fig. 1 is a side view and
Fig. 2 a plan view of locking apparatus for bicycles of the kind herein before
-described.
Fig. 3 is a vertical sectional view of the apparatus when the bolt of the lock is
shot out or in locking position and
Fig. 4 is a similar view but with the bolt withdrawn.
Figs. 5 and 6 shew the apparatus in elevation and sectional view respectively as
affixed to the socket of the front fork of a bicycle.
:and
Fig. 7 is a side view of a bicycle having our improved apparatus applied thereto
Fig. 8 is a plan view of the same shewing the position in which the front wheel A
is securely held when in its locked position.
The lock mechanism is arranged within a box a forming a short arm from one of a
pair of metal clips bbwhich are drawn together and secured to the front fork
socket c by the screws d d.
e is the bolt impelled outwardly by the spring finger f. The outer extremity e¹
of the bolt is round and passes through a suitable hole whilst the inner part of the
said bolt is flat and has a slotted part e' working on a guide pin g. The pin g also
answers as the axis for the pivotted tumblers h. is the key hole and m the key
pin. When unlocking the apparatus the furthest key ward presses against the
projecting part e³ of the bolt and forces the said bolt back to the position shewn
at Fig. 4 whereupon the spring catch or detent i drops down and engages with the
hook part e of the bolt and so retains it in its unlocked position. The button j
is attached to the detent i thus affording the required facility for releasing or
disengaging from the outside the detent i from the bolt e so as to allow the bolt to
be free to slip automatically into the hole in the fork stem when the front wheel is
.moved round to the position shewn at Fig. 8.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The use or employment with a bicycle of locking apparatus substantially no
described for the purpose specified.
