PROVISIONAL SPECIFICATION.
Improvements in Perambulators or similar Vehicles.
I, FRANK HARVEY Engineer 64 Strode Road, Willesden Green N.W.in' the
County of Middlesex, do hereby declare the nature of this invention to be as
follows:-
My invention has for its object to provide perambulators or similar. vehicles
with a brake such that the brake is automatically put on, when the person by.
whom the perambulator is propelled leaves go the handle of the perambulator or
the like.
The normal position of the brake is "on." The brake may take the form of
four arms or two double arms to the outer ends of which are attached the rubbing
pieces or brake blocks which engage with the tyres of the wheels or one of the
wheels when the perambulator hardle is not grasped, but when the handle is so
grasped, a lever, chain, or analogous device is moved in such a manner that the
brake blocks or rubbing pieces are withdrawn or lifted from the tyres of the wheel,
or wheels, but when the attendant leaves go the handle of the vehicle the brake
blocks automatically engage with the tyres of the wheel or wheels and so the brake
is put on.

COMPLETE SPECIFICATION.
Improvements in Perambulators or similar Vehicles. : .
I, FRANK HARVEY, of 64, Strode Road, Willesden Green, in the County of
Middlesex, 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 :-
My invention relates to an improved construction of brake for perambulators
and similar vehicles, which brake is normally upon the wheels and must be lifted
therefrom before the perambulator or the like can be propelled.
In carrying out my invention I pivot to one of the axles of the vehicle two pairs
of arms carrying at their free ends rubbing-pieces or brake-blocks adapted to bear
upon the wheels upon the said axle.
I move the brake-blocks away from the wheels either by rotating the handle-bar
to tighten cords or chains or by moving a lever to which cords are connected.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings, in which :-
:-
Figure 1 is an elevation of a perambulator provided with my improved brake-
mechanism; and,
Figure 2 is a plan of the perambulator with the body removed:
Figure 3 is a view similar to Figure 1 but shewing the arrangement wherein a
lever is employed for operating the brake:
Figure 4 is a plan view illustrating the arrangement of the said lever.
a, a are the hind wheels of a perambulator, and is the axle upon which the
said wheels rotate. c, c, c', c¹ are two pairs of arms which are pivotted at d, d to
brackets on the axle band connected together by the tie-rods e, e respectively.
ffare the brake-blocks carried by the said arms and which when the latter are
in the horizontal position indicated by the full lines in Figures 1 and 3 are designed
to bear against the tyres of the wheels a, a: when, however, the said arms are

page_text: moved to the position indicated by the dotted lines in Figure 1 then the brake-
blocks are removed from the wheels.
As shewn in Figures 1 and 2 the pairs of arms c, c, c¹, c¹ are lifted by cords g, g'
respectively, which cords pass over suitable pulleys, as shewn, to the handle h of
the perambulator which is adapted to be turned. It will be understood that the
weight of the levers c, c¹ will tend to hold the brake-blocks upon the wheels and
that in order to lift the said brake-blocks away from the wheels it is necessary to
rotate the handle h.
In the arrangement shewn in Figures 3 and 4 the cords or chains g, gl are
connected to a ring i suspended from a lever i pivotted at j to the body of the
perambulator and having a hand-piece k designed to fit against the handle h of the
perambulator which in this case does not turn. As the weight of the lever might
be sufficient to counterbalance the weight of the arms c, c, c¹, c¹ and so hold the
brake-blocks away from the wheels I provide the spring between the ring and
the axle b to hold the brake-blocks upon the wheels. In order to lift the brake
from the wheels it is only necessary to grasp the hand-piece k of the lever i and
the handle h simultaneously.
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 improvements in perambulators or similar vehicles consisting in providing
such vehicles with pivotted arms carrying brake-blocks which normally bear against
the wheels and which must be lifted from the wheels before the vehicle can be
propelled, substantially as described.
2. In a perambulator or similar vehicle two pairs of pivotted arms carrying
brake-blocks, the said arms being adapted to be moved to lift the brake-blocks off
the wheels by rotating the handle of the perambulator or similar vehicle, substan-
tially as described by reference to Figures 1 and 2 of the drawings or by moving
a lever, substantially as described by reference to Figures 3 and 4 of the drawings.
Dated this 8th day of March 1893.
