Complete Specification Left, 22nd June, 1894-Accepted 28th July, 1894.
PROVISIONAL SPECIFICATION.
Apparatus for Locking the Wheels of Vehicles.
I, FREDERIC HUGHES, of No. 20 Paget Road, West Dulwich in the County of
Surrey, Mechanical Engineer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to apparatus for locking the wheels of a vehicle when
brought to a standstill, so as to reduce the risk of a horse running away with such
vehicle when left unattended.
For this purpose, I mount on a vertical axis on any convenient part of the
bottom of the vehicle a lever which is held in its normal position by means of a
suitable spring so that one of its arms projects between two of the spokes of one of
the wheels of the vehicle; thus preventing it from being turned round. The other
arm is connected by means of a chain or an arrangement of levers with a handle or
pedal on the drivers seat so that by moving this handle or pressing on the pedal he
can actuate the lever so as to withdraw the arm from between the spokes, and lock
the lever in that position. On releasing the handle or pedal when leaving his seat,
the projecting arm is caused by the spring to enter between two of the spokes
of the wheel and lock it.
Dated this 7th day of May 1894.

COMPLETE SPECIFICATION.
Apparatus for Locking the Wheels of Vehicles.
I, FREDERIC HUGHES, of No. 20 Paget Road, West Dulwich, in the County
of Surrey, Mechanical Engineer, 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 to apparatus for locking the wheels of a vehicle when
brought to a standstill, so as to reduce the risk of a horse running away with such
vehicle when left unattended. For this purpose I arrange on the vehicle apparatus
such as is illustrated by the accompanying drawings.
Fig. 1 is a part transverse section and Fig. 2 is a part plan.
I mount on a vertical axis A on a convenient part of the bottom of the vehicle a
lever arm L which is held in its normal position by means of a suitable spring S so
that it projects between two of the spokes of one of the wheels W of the vehicle,
thus preventing it from being turned round.
Another arm or a pulley P on the axis A has attached to it a strap or chain C
which can be secured to a hook or other fastening, or it might be connected to a
handle or pedal on the driver's seat so that by pulling up the strap or chain or by
moving this handle or pressing on the pedal he can withdraw the arm L from
between the spokes, and lock it in that position. On releasing the strap or chain
or the handle or pedal when leaving his seat, the projecting arm L is caused by the
spring S to enter between two of the spokes of the wheel and so lock it. To
prevent the arm L from injuring the spokes of the wheel it is preferably covered
with india rubber or other suitable pad.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what
I claim is :-
For locking the wheel of a vehicle, an arm urged by a spring to a position
between two spokes of the wheel and having a connection by which it can at will
be withdrawn, substantially as described.
