PROVISIONAL SPECIFICATION.
A New or Improved Automatic Brake for Bassinettes, Perambulators,
and other like Vehicles.
We JOHN SCOTT MARLAND, Yarn Agent, JAMES SCOTT MARLAND, Clerk
and WILLIAM WYLIE MARLAND, Brass Finisher, all of 12 Wall Street, Park
Road, Oldham, in the County of Lancaster, do hereby declare the nature of our
said invention to be as fo'lows :-
:-
This invention consists in employing the supporting rods of the handles of
bassinettes, perambulators and other like vehicles as a means of automatically
controlling a brake appliance situated beneath the body of the vehicle to effectually
scotch and prevent the vehicle running backwards or forwards when left standing
on an incline.
In carrying out our invention instead of rigidly affixing the supporting rods to
the vehicle as heretofore we now mount the same on a short arm or its equivalent
branching from the body of the vehicle and being supported thereby are capable
of oscillating to and fro in a direction parallel therewith.
And underneath the vehicle and arranged in a line with the rims of one set of
wheels, preferably the larger set, is a horizontal rod or shaft which is supported by
preference in bearings depending from the underside of the vehicle, and upon the
respective ends of which shaft is affixed a brake shoe, so adjusted in position
thereupon as to come opposite and of its own weight fall onto the rim or tyre of the
wheel.
At a suitable distance apart a pair of short arms project from the shaft, which
are connected at their extremities to the ends of the supporting rods herein before
mentioned by suitable connecting rods.
"
By these means it will be readily apparent that as the handle is grasped and
pushed or pressure is exercised thereupon, the brake shoes will be raised out of
contact with the wheels, but immediately the handle is "let go
again or the
pressure diminishes the brake shoes simultaneously fall and effectually scotch the
wheels.
The brake shoes may be weighted to counterbalance the weight of the handle
and supporting rods or a spring may be applied to the horizontal rod to cause it to
always tend to bring the shoes into play with the wheels.
The horizontal rod in some cases might be supported on the flat springs of the
vehicle or may be otherwise conveniently supported. To ensure greater certainty
of action the brake shoes may in some cases work independently of each other.

COMPLETE SPECIFICATION.
A New or Improved Automatic Brake for Bassinettes, Perambulators,
and other like Vehicles.
We, JOHN SCOTT MARLAND, Yarn Agent, JAMES SCOTT MARLAND, Clerk,
and WILLIAM WYLIE MARLAND, Brass Finisher, all of 12 Wall Street, Park
Road, Oldham, in the County of Lancaster, do hereby declare the nature of our
said 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 consists in employing the handle bars or supporting rods of the

page_text: handles of bassinettes, perambulators, and other like vehicles, as a means of
automatically controlling a brake appliance situated beneath the body of the
vehicle to effectually scotch or prevent the vehicle running backwards or forwards
when left standing on an incline.
And in order that this our said invention may be better understood and more
readily carried into effect we have hereunto annexed a sheet of drawings showing
the application of our invention to a perambulator and will now proceed to describe
the same by means of the figures and letters of reference marked thereon.
Fig. 1 is a side elevation of a perambulator and Fig. 2 a plan of so much of the
underframe as will be needful to show what we have found to be the best method of
carrying out our invention. A. A. are the supporting rods for the handle A which
instead of being fixed to the body of the carriage as heretofore are in accordance
with our invention pivoted on short arms B. B. branching from the perambulator
body as illustrated thus permitting of an oscillating movement. Underneath the
carriage body and in a line with the rims of one pair of wheels (in this case the
front pair) we affix a pair of brake shoes C. C. on the ends of a horizontal rod D
working in a spring box E (see detail view Fig. 3). In this spring box will be
seen a spring whose function is to press the horizontal rod D and therefore the
brake shoes C. C. into contact with the wheels unless they are drawn out of contact
by the pushing forward of the handle for which purpose the lower ends G of the
handle rods A. A. are connected to the horizontal rod D through the connecting
rod H. It will thus be seen that the brake shoes C. C. are always in contact with
the wheels except in the act of pushing the vehicle when they are automatically
withdrawn by the slight forward movement of the handle rods turning upon the
short arms B. B.
In this manner we effectually scotch or prevent the vehicle moving either
backwards or forwards except under the push of the handle in the act of wheeling
and in this manner we produce a brake device which is automatic and free from the
defects of previous devices, for the purpose.
In our Provisional Specification we mentioned that the handle rods might be
operated by pressure exercised upon them in lieu of being pushed as in the act of
wheeling the vehicle. In such case we should support the rods by preference on
springs strong enough to raise the rods to their full height but capable of being
depressed by the weight of the hand resting upon the handle and the downward
movement thus obtained is utilised to lift the brake shoe C. C. out of contact with
the wheels as in the previous modification but immediately the handle is "let go
the brake shoes come into action. Instead of using springs we might utilize the
weight of the brake shoe to counter-balance the weight of the handle rods.
be obvious that our invention is equally applicable to bassinettes, bath-chairs,
and other like vehicles which are propelled in a similar manner to perambulators.
Having thus particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what we
claim is :-
It will

operating substantially as herein before described and illustrated on the accom-
panying drawing.
