PROVISIONAL SPECIFICATION.
An Instantaneous Automatic Brake to be applied to Perambulators
or other Manumotive Vehicles.
GEORGE FARMER and WILLIAM MILBURN trading as Farmer, Lane & Co.,
at 77-79 New Oxford Street, London, W.C. Manufacturers of Invalids'
Furniture, Baby Carriages Perambulators etc. do hereby declare the nature of this
invention to be as follows:-
A self-acting brake, the motive power of which is applied by means of a lever:
this lever has a light cross bar attached at right angles to its outer extremity,
which is grasped simultaneously with the handle (along which it lies flat) of the
perambulator, by the hands of the propeller.
The inner extremity of the lever is hooked on to flexible band coiled round a
drum fixed to the revolving axle of the back wheels (on the locomotive principle)
the other end of the band being screwed to the bottom of the carriage.
At the junction of the lever and band a powerful spring is attached, which when
the lever is dropped from the hands, draws up the band and coiling it round the
drum completely locks the wheels.
Dated this 26th day of February 1891.

COMPLETE SPECIFICATION.
An Instantaneous Automatic Brake to be applied to Perambulators
or other Manumotive Vehicles.
We, GEORGE FARMER and WILLIAM MILBURN, trading as Farmer,
Lane & Co., 77-79 New Oxford Street, London, W.C., Manufacturers of
Invalids Furniture, Baby Carriages Perambulators &c. 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 motive power in working this brake is applied by means of a lever marked A
on drawing, the fulcrum (H) of which is close to the well or bottom of the vehicle;
this lever the length of which depends on the height of the propelling handle (G)
from the back axle, has a light cross bar or rod, made of metal, or other suitable
material attached at right angles to its upper limit (F) the said bar or rod being
grasped simultaneously with the handle (along which it lies flat) of the perambulator
or other manumotive vehicle, in the hands of the propeller when the carriage is in
motion.
The inner or lower extremity of the lever is hooked on to a flexible metallic
band (B), which coils round a drum (G) immovably fixed to the revolving axle (on
the locomotive principle) of the back wheels, the other end of the band being
attached as hereinafter described.
At the junction opposite to where the lever is hooked to the flexible band, which
encircles the drum on the axle, a powerful compressed spiral spring (D) is fixed,
cased in a vertical cylinder (E) to protect it from outward injury, which cylinder is
in turn screwed or bolted by means of projecting tangent-wise flanges to the outer
end of the carriage well, directly over the drum, the other extremity of the band
aforesaid, being hooked on to the spring in question.
When the cross arm of the lever drops (Fig. 2) from the hands of the person
wheeling, this spiral spring acts ou the flexible band, and pulling it up, locks the

page_text: axle completely, thus affording absolute security, by preventing any possible motion
of the vehicle, till the lever is again brought into play by the propeller laying hold
of the cross bar with the handle of the carriage, thus counteracting the haulage
exercised by the spring freeing the drum from the embrace of the flexible band
(Figs. 1 & 3) and allowing of locomotion.
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 :—
