PROVISIONAL SPECIFICATION.
Improvements in Brakes for Perambulators.
I, WILLIAM JOHN PARKER, of 104 Curtain Road, Shoreditch, in the County of
Middlesex, Manufacturer, do hereby declare the nature of my said invention to be as
follows:-
My invention relates to a certain form of brake to be applied to perambulators, for
which provisional protection has been granted to George Henry Capewell Hughes,
dated 4th January 1887, No. 110, and the object of my invention is to effect certain
improvements therein.
The invention above referred to consists of a crank forming part of a rod, suitably
mounted, in a horizontal position, in such a manner that, by turning such rod through
a portion of a circle (90 degrees or thereabouts) the crank passes between the spokes
of one of the wheels, and thereby effectually prevents the rotation of any wheel, to
which it may be applied, until the removal of the same by turning it back again.
Now my improvement consists in fitting another crank to the outer end of such
horizontal rod, and applying to such additional crank, a vertical, or nearly vertical
connecting rod, which is supported near its upper end, by a suitable staple fixed to the
perambulator; above which staple a suitable handle is fitted to the connecting rod for
raising and lowering the same by hand.
The outer crank and connecting rod may be arranged so that the brake may be
applied by either the up or down movement of the same, one of such movements
being used for applying the brake, and the other to release the same.

Improvements in Brakes for Perambulators.
I WILLIAM JOHN PARKER of 104 Curtain Road Shoreditch in the County of
Middlesex Manufacturer do hereby declare the nature of my 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 a certain form of brake to be applied to perambulators
which brake was described in the provisional specification filed with his application
for patent made by George Henry Capewell Hughes on the 4th day of January 1887
No. 110 and also in the complete specification filed by the said G. H. C. Hughes and
accepted on the 7th day of October 1887 and the object of my invention is to effect
certain improvements in the said brake.
The invention above referred to consists of an arm stop or crank forming part of a
rod suitably mounted in a horizontal position in such a manner that by turning such
rod through a portion of a circle (90 degrees or thereabouts) the arm or stop passes
between the spokes of one of the wheels and thereby effectually prevents the rotation
of the wheel to which it may be applied until the removal of the same by turning it
back again.
My improvements consist in fitting a crank or crank plate to the outer end of such
horizontal rod and applying to such additional crank a vertical or nearly vertical
connecting rod which is supported near its upper end by a suitable staple fixed to the
perambulator above which staple a suitable handle is fitted to the connecting rod for
raising and lowering the same by hand.
The outer crank and connecting rod may be arranged so that the brake may be
applied by either the up or down movement of the same one of such movements
being used for applying the brake and the other to release the same.
Figure 1 of the accompanying Drawing represents in side elevation a portion of a
perambulator with which is combined a stop brake of the kind before referred to the
said stop brake being worked by mechanism constructed according to my invention.
Figures 2 and 3 represent elevations taken at right angles to one another and Figure 4
represents in plan the brake, brake mechanism and a portion of the perambulator
wheel drawn to a larger scale. In Figure 1 the brake is represented taken out of
action and in Figures 2. 3 and 4 in action.
The same letters of reference indicate the same parts in the several Figures of the
drawing.
a is the rotating brake rod turning in bearings at bb fixed to the axle of the
perambulator and c is the arm or stop on the lower end of the said rod and at right
angles thereto. By the motion of the rod a through a quadrant the said arm or stop c
is made to engage between the spokes of the wheel d of the perambulator as repre-
sented in Figures 2, 3 and 4 and thereby arrest the motion of the vehicle. By
moving the rod a in the opposite direction its arm or stop c is withdrawn from between
the spokes of the wheel d and brought into a nearly vertical position in which position

page_text: it offers no obstruction to the motion of the vehicle as represented in Figure 1 and
indicated in dotted lines in Figure 2. The mechanism for operating the brake
consists of a handle e at the rear end of the perambulator the bottom of the rod j
of the said handle being jointed to a crank pin on one end of the crank or crank
plate the other end of the said crank or crank plate 9 being rigidly connected to
the top of the prolongation a of the rotating brake rod a. The connecting rod f
works in the staple or bracket f2 on the side of the perambulator. By pulling
upwards the handle e it operates the crank or crank plate g and causes the brake
rod a to be turned through a quadrant and the arm or stop c made to engage between
the spokes of the wheel d as seen in Figures 2. 3 and 4. By depressing the handle e
into the position represented in Figure and indicated in dotted lines in Figures 2
and 3 the motion of the brake rod a is reversed and the arm or stop c withdrawn
from between the spokes of the wheel as represented in Figure 1.
Instead of putting the brake into action by the raising of the handle e and con-
necting rod the brake may be put into action by depressing the said handle e and
rod f
Although I have represented the operating mechanism as applied to a brake of
the kind before described yet the said operating mechanism may be applied to other
brakes for perambulators which are put into and taken out of action by the partial
rotation of a rod.
Having now particularly described and ascertained the nature of my invention and
the manner in which the same is to be performed I declare that what I claim as my
invention of "Improvements in brakes for perambulators."
Operating stop brakes for perambulators of the kind herein before described and
other like brakes by hand worked mechanism consisting essentially of the crank or
crank plate g one end of which is connected to the brake rod and the other end is jointed
to a connecting rod and handle the motion of the said handle and connecting rod
putting the brake into and taking it out of action substantially as herein before
described and illustrated in the accompanying Drawing.
Dated this Seventeenth day of October 1887.
