Improved Means for Locking against Rotation the Wheels of
Perambulators and other Vehicles.
We JOSEPH BRINDLE of 14 Field Street Failsworth in the County of Lancaster
Mechanic RICHARD LOVETT READE of New Hall Wythenshaw Road Sale in the
County of Chester Merchant and JOHN TAYLOR of 181 Northenden Road Sale in the
County of Chester Merchant, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to afford a ready means of locking the wheels of
perambulators and other vehicles so as to prevent the liability of their running away
if left unguarded upon a sloping or uneven surface.
The invention consists principally of a clutch box made in two parts, one of which
is fixed upon the inner side of the hub of the wheel, and the other is mounted so as to
slide endwise upon the squared or other part of the fixed axle. The approximate
faces of these two parts are made with alternato projections and corresponding recesses
so that when the one is slidden endwise into contact with the other they become
interlocked and the wheel is prevented from revolving. The movable part of the
clutch box is made with a recess or neck into which takes a short lever or finger
projecting from one end of a horizontal shaft, the other end of which is turned up and
made into a spring lever the end of which is within easy reach of the cross handle.
The spring lever-acts against a notched bar so that by moving it either to the right or
left and allowing it to spring into one or other of the notches the clutch box is held
either in or out of gear as the case may be.

COMPLETE SPECIFICATION.
Improved Means for Locking against Rotation the Wheels of
Perambulators and other Vehicles.
We JOSEPH BRINDLE of 14 Field Street Failsworth in the County of Lancaster
Mechanic, RICHARD LOVETT READE of New Hall Wythenshaw Road Sale in the
County of Chester Merchant and JOHN TAYLOR of 181 Northenden Road also of Sale
in the County of Chester Merchant 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 object of this invention is to afford a ready means of locking the wheels of
perambulators and other vehicles so as to prevent the liability of their running away
if left unguarded upon a sloping or uneven surface.
The invention will be readily understood from the following description on reference
to the annexed sheet of drawings on which Fig. 1 is an elevation of one end of a
perambulator with our improvement applied thereto, and Fig. 2 is a side view of the
same with the wheel (marked a on Fig. 1) removed. Fig. 3 is a plan view of a
detached part hereafter more particularly referred to.
The invention consists principally of a clutch box b, b' made in two parts, one of
which (b) is fixed upon the inner side of the hub of the wheel a and the other (61)
is mounted so as to slide end wise upon the squared or other part of the fixed axle c.
The approximate faces of these two parts b, b' are made with alternate projections
and corresponding recesses so that when the part is slidden endwise into contact

revolving.
The movable part of the clutch box is made with a recess or neck into which
takes a short lever or finger d projecting from or forming part of a horizontal shaft
or rod d' the other end of which is turned up and made into a spring lever d², the end
of which is within easy reach of the cross handle e.
they become interlocked and the wheel a is prevented from
The spring lever d², acts against a notched bar or a slotted plate f (see also Fig. 3)
so that by moving it either to the right or left and allowing it to spring into one or
other of the notches or depressions the clutch b' is held either in or out of gear as the
case may be.
The arm d is also made (by preference) so that it can yield or give way in case
the wheel is in such a position that the clutches b, will not immediately interlock
but as soon as the wheel a has revolved sufficiently to allow of such interlocking the
arm d will act as a spring to force the part 6' into gear with the part b.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The improved means for locking against rotation the wheels of perambulators and
other vehicles substantially as hereinbefore described and illustrated by the annexed
drawings.
