An Improved Device for Automatically Stopping the Rotation of the
Wheels of Perambulators and other similar Vehicles.
I, THEODORE ARTHUR IZOD, of No. 5 Queen Anne Road, South Hackney, in the
County of Middlesex, Butcher, do hereby declare the nature of this Invention to be
as follows
My invention relates to an improved device for automatically stopping the rotation
of the wheels of perambulators and other similar vehicles, whenever the same cease
to be under proper control.
It is well known that accidents occur constantly owing to the carelessness of those
in charge of perambulators who suddenly release their hold upon the handles thereof
perhaps on a steep incline whereby the said perambulator starts and runs with its
occupants off the pavement into the gutter when it is overturned or into the road
where it is liable to be knocked down by the passing traffic.
Now according to my invention whenever the handle of a perambulator is released,
mechanism is brought automatically into play whereby two rods are thrust out
between the spokes of the hind wheels and thus stop their rotation and likewise the
motion of the perambulator.
In carrying my invention into practice I provide a bar or rod, the top extremity
of which is bent around the handle of a perambulator so as to form a ring capable
of sliding loosely thereon. The lower end of this bar or rod is fixed to one
extremity of a lever oscillating upon a pin mounted in the centre of a longitudinal
plate fixed to the underside of the perambulator frame. The other extremity of this
lever terminates in the form of a hook to which is attached one end of a spiral
spring whose other end is conveniently fixed to the underside of the perambulator
frame.
At a short distance from its two extremities are attached to the above lever the
curved ends of two rods travelling through guides fixed to the underframe and
designed when solicited by the action of the spiral spring to enter between the
spokes of the wheels of the perambulator.

page_text: Wheels of Perambulators and other similar Vehicles.
I, THEODORE ARTHUR IZOD, of No. 5 Queen Anne Road, South Hackney, in the
county of Middlesex, Butcher, 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 an improved device for automatically stopping the rotation
of the wheels of perambulators and other similar vehicles, whenever the same cease
to be under proper control.
It is well known that accidents occur constantly owing to the carelessness of those
in charge of perambulators, who suddenly release their hold upon the handles thereof
perhaps on a steep incline whereby the said perambulator starts and runs with its
occupants off the pavement into the gutter when it is overturned, or into the road
where it is liable to be knocked down by the passing traffic.
Now according to my invention whenever the handle of a perambulator is released
mechanism is brought automatically into play whereby two rods are thrust out
between the spokes of the hind wheels and thus stop their rotation and likewise the
motion of the perambulator.
And, in order that my invention may be more fully understood, I shall now proceed
to describe the same with reference to the accompanying drawings in which Fig. 1 is
a back elevation of a perambulator whose hind wheels are fitted with my improved
break apparatus. Fig. 2 is an underside view of the said perambulator showing only
the portion thereof which carries the said apparatus. Fig. 3 is a side view of the
rear part of a perambulator likewise furnished with my improved automatic stopping
apparatus.
To the underside of the bottom board B. of the perambulator frame P, I fix by
screws or otherwise a plate A. separated from the board B. by four corner blocks or
supports ss to allow the necessary space for the double-armed lever to oscillate upon
a pin p. fixed on the top of the said plate A.
One extremity of this lever is furnished with a hook . to which is fixed one end of
a spiral spring. whose other end is attached to a hook screwed in the board A.
The other extremity of the lever L. is provided with a screw threaded pin carrying
a nut and around which is bent in the form of an eye the lower end of a bar or
lever pivoting upon la pin o centrally mounted upon the strap 3. The other end of
this lever or bar / terminates above the handle H. of the perambulator and assuming
a curved shape as shewn at E. in the drawing, or may be bent round so as to form a
ring. Close to the two extremities of the lever L. are fixed by rivets or otherwise the
two cranked extremities of two bolts & capable of running through tubular guides
formed in the centre of the guide plates 9 g fixed to the plate A. These two bolts
move in opposite directions as clearly shown in the drawings, and their extremities
are provided with india-rubber caps to prevent them from injuring the spokes of the
wheel when abutting against them.

page_text: Fig. 1 shows in full lines the position of the lever and bolts when the latter
are shot automatically, while the position of the same lever when the bolts are off is
shewn therein in dotted lines.
The position of the lever in Fig. 2. is similar to that shewn in full lines in Fig. 1..
and the same applies to Fig. 3.
When it is required to move a perambulator fitted with my improved automatic
stopping apparatus, the end E. of the lever must be pushed with the hand to the
right end of the handle H and held there as shewn in dotted lines in Fig. 1. thus
turning the double armed lever L. to the left hand side and disengaging the bolts
which are now moved away from the wheels. But whenever and by whatever
fortuitous or other cause the handle H. of the perambulator is released, the extremity /
of the lever L. solicited by the action of the spiral spring is pulled to the right
hand side and the bolts bb are shot between the spokes of the wheels, thus arresting
their motion and consequently that of the vehicle.
Having thus 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
1) The improved automatic apparatus for stopping the rotation of the hind
wheels of perambulators whenever the handle thereof is released, characterized by a
plate A. furnished with a pivot p upon which oscillates a double armed lever carrying
the ends of two bolts moving through guides and to whose extremities are respectively
fixed a spiral spring, and a vertical or curved bar or lever bent at its upper extremity
or terminated by a ring passing over the handle of the said perambulator substantially
as described and shewn and for the purpose set forth.
2) My improved automatic stopping apparatus arranged, combined and operating
substantially as and for the purpose described.
