PROVISIONAL SPECIFICATION.
A Self-acting Brake for Perambulators, Mail Carts, Bath Chairs,
or the like.
WILLIAM THOMAS ROUNSIVELL, Mechanical Engineer, of 25, Kitto Road, Nunhead,
London, S.E., do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide a means of applying a brake or retarding
mechanisin to any hand propelled vehicle such as perambulators, mail carts, Bath
chairs or the like, causing them to be instantly brought to a standstill automatically
when left unattended, or when the hand or hands are removed from the driving
handles.
The invention consists of a handle a, made to revolve freely in its bearings. On
this handle, rigidly fixed, one at each end, are two curved levers 61 62. From one
end of handle a cord, chain or wire c, is fastened. Upon suitable brackets under the
carriage is fixed an axle d, carrying two ordinary brake spoons el e², so arranged to
engage into two wheels. The other end of cord c is attached to lever g.
A spring fin tension, connects lever g and keeps spoons tight upon wheels.
The action of brake is as follows:-The accompanying design shews the invention
applied to a perambulator at rest. When it is desired to move it, the projecting
levers b, are revolved in direction of arrow, until they match the main handles.
This winds the cord c, around the handle pulling lever g against the spring f, thus
releasing the spoons. The moment the hands are removed from the handles b', 62,
the spring being always in tension, at once pulls levers b¹, 62 back in the position
of drawing, causing the spoons to grip the wheels. The motion of the perambulator
is immediately arrested in the event of any careless person letting go the handles.
This invention is also intended for use in checking descent of such hand propelled
vehicles as before mentioned in going down hill, the levers 61, 62 being used in the
same manner as an ordinary brake.

WILLIAM THOMAS ROUNSIVELL, Mechanical Engineer, of 25, Kitto Road, Nunhead,
London, S.E., 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 :-

chairs or the like, causing them to be instantly brought to a standstill automatically,
when left unattended, or when the hand or hands are removed from the driving
handles. Drawings left with the Provisional Specification. The invention consists
of a handle a, made to revolve freely in its bearings. On this handle rigidly fixed,
one at each end, two curved handles b1, b2 project from the revolving handle a. "From
this handle a, a cord chain or wire a is fastened. Upon suitable brackets under the
carriage is fixed an axle d, carrying two brake spoons e¹, e², so arranged to to engage
into two wheels. The other end of the cord, chain or wire is attached to the lever g.
A spring f, in tension, connects lever g, and keeps spoons tight upon wheels.
The action of brake is as follows:-The drawings left with the Provisional
Specification shews the invention applied to a perambulator at rest. When it is
desired to move it, the projecting levers 61 62 are revolved in the direction of the
arrrow, until they match the main handles. This winds the cord c, around the
handle pulling lever g against tension of spring f, thus releasing the spoons.
The moment the hands are removed from levers 61, 62, the spring, being always in
tension at once pulls the levers back into the position shewn on drawing, causing the
spoons to grip the wheels.
The motion of the vehicle is immediately arrested in the event of any careless
person letting go the handles. This invention is also intended to be used in checking
the descent of such hand propelled vehicles as before described, in going down hill,
the levers b', b2 being used in the same manner as an ordinary brake.
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:-
(1) The application of a revolving handle with projecting levers in combination
with the spoon brake & spring in the arrangement as herein and before described
and illustrated.
(2) The same combination of parts as herein and before described acting upon two,
three or four wheels of such vehicles as herein and before mentioned.
(3) The application of lever or levers as herein and before mentioned without the
revolving handle.
