HARRY ARTHUR WOOD MIDDLEDITCH Electrical Engineer Lyminster Sussex
do hereby declare the nature of this invention to be as follows :—
An invention for applying the brake on perambulators & vehicles by means of
an automatic mechanical appliance by means of a spring which is held in tension
whilst the motive or propulsion power is on and acts immediately the motive or
propulsion power ceases.
An invention for applying the brake on perambulators and vehicles by means of
an automatic mechanical appliance by means of a spring, the said spring is fixed to
axle or other suitable place it is connected to brake rod by means of a bell
crank.
The bell crank on brake rod is connected to handle or book by means of a
connecting rod which having a lever arrangement so that the spring becomes
compressed by the pushing or drawing motive power so that the
caused'
pressure
by spring is relieved by the aforesaid powers, but when the vehicles is at rest
the full pressure or pull of the said spring is utilised by brake blocks gripping the
wheels.

HARRY ARTHUR WOOD MIDDLEDitch Lyminster, Arundel, Sussex Electrical
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 :-
This invention relates to an improved apparatus for the purpose of automatically
applying the brake to perambulators mail carts and vehicles wheels on which
vehicle the appliance is fixed. The action is completely automatic.
The brake is applied by the pull or push of a spring which spring is compressed
by the power used in hauling or propelling the vehicle. Upon the hauling or
propelling ceasing the pull or push of spring is transmitted to the brake block by
means of a crank, rod, or other mechanical means.
I prefer to use mechanical arrangements actuated by handles or hooks to which
the hauling or propulsion power is applied.
A spring is fixed in a convenient place on the vehicle and connected to the brake
rod by means of a bell crank, on the brake rod, to connecting rod which connects
to crank or lever arm on handle or the spring fits as a sleeve over rod which connects
to friction block one end and to hook for hauling gear the other end. The spring
becomes compressed by the hauling or propulsion power so that the pressure caused
D

the full pull or pressure of the said spring is utilised by the friction blocks gripping
the wheels.
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet of drawings shewing the mechanicle device I propose to
employ in which
Fig. 1 is a side elevation of the complete arrangement.
Fig. 2 is a back elevation.
Fig. 3 is a section of the mechanical parts as used for a perambulator.
a is the handle B is a crank fixed to handle to form lever c is a connecting rod
connecting B to d which is arm of bell crank dd. F. is tension rod connecting
arm of bell crank d to spring e provided with a nut for regulating tension of spring
Kis provision made in handle a to receive link fixed in the top of H H Fig. 2 so
as to form lever when handle is pressed upon. R Fig. 2 is the brake rod which
passes through handle stays H H, in which s s are bushes. Bell crank d d is fixed
to brake rod R by means of a set screw. The rod M is fixed in B B and the
handle a a works upon links fixed in the top of H H.
Fig. 4 is a side elevation of complete arrangement for mail cart or vehicle.
B is the connecting rod c is the spring d is a fixed collar which receives the push
of the spring c.
e and e1 are guides through which the connecting rod B passes
and when drawn back by the raising of handle a the spring c is compressed
between el and fixed collar d. When connecting rod is released the push of
spring against fixed collar, d, presses friction block, F, against wheel.
Fig. 5 is section of parts-For hauling gear a hook is fixed on the end of
connecting rod.
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. An improved apparatus for applying brake to wheels of vehicles on which
the apparatus is fixed. To prevent vehicles running away, consisting of friction
blocks brake rod, crank, connecting rod and lever as and for the purpose
specified.
II. An improved apparatus for automatically applying the brake to wheels of
vehicles consisting of a mechanical arrangement of springs rods, levers and cranks
and means whereby the brake is applied when the hauling or propulsion power
ceases as described and for the purpose specified.
III. An improved apparatus of the kind described the combination of a spring
crank, lever, rod, hook handle fixed to the vehicle operated by the hauling or
propulsion power substancially described and for the purpose specified.
Dated this 26th day of September 1895.
