PROVISIONAL SPECIFICATION.
Improvements relating to Hand Trucks or Waggons.
We, EDGAR CARTER, of 1, Mount Street, Southport, Baker, and WILLIAM
HENRY HOLLAND, of 38, Chambres Road, Southport, Soap Manufacturer, do
hereby declare the nature of this invention to be as follows:-
:-
This invention relates to improved means for applying a brake to the wheels
of railway platform trucks and similar hand carriages.
In applying this invention to an ordinary four-wheeled truck, of which the
front wheels are upon a swivel and are provided with a handle--which is also
swivelled so that may be raised and lowered-we form a boss upon the inner
surface of each of the front wheels and we arrange band brakes to be tightened
around such bosses by the said handle when in its lower position.
The said handle will be bifurcated at its lower end as usual, the two branches
thereof being led to the sides of the swivelled under carriage, where they will
be fulcrumed upon a bar carried in front of such undercarriage. To the extremity
of each of the branches are attached one end of each of the band brakes above
referred to, whilst the other ends of the bands are secured to the under-carriage.
In operation the bands are slackened upon the wheel bosses when the handle
of the truck is raised, so that the wheels are free to revolve, but when the handle
is quitted, and falls the bands are tightened around the bosses by the weight
and leverage of the handle, and a brake is thus applied to the wheels.
Dated this 5th day of December 1898.

Improvements relating to Hand Trucks or Waggons.
We, EDGAR CARTER, of 1, Mount Street, Southport, Baker, and WILLIAM
HENRY HOLLAND, of 38, Chambres Road, Southport, Soap Manufacturer 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 improved means for applying a brake to the wheels
of railway platform trucks and similar hand carriages.
In applying this invention to an ordinary four wheeled truck, of which the
front wheels are upon a swivel and are provided with a handle-which is also

page_text: swivelled so that it may be raised and lowered--we form a boss upon the inner
surface of each of the front wheels, and we arrange band brakes to be tightened
around such bosses by the release of said handle.
Our invention is illustrated in the annexed drawings in which Figure 1 is
a side elevation and Figure 2 an underside plan of the front portion of a common
hand truck. Figure 3 illustrates a modified form of our invention.
Reference to Figures 1 and 2. The handle a is bifurcated at its lower end and
the two branches thereof are fulcrumed on the rod b. These branches pass
through the axle-tree and in their extremities is carried a rod c. The handle a
thus forms a lever of the first order. To the inside of each of the wheels d
is fitted a boss e which may be of wood, and partially extending around these
bosses are band brakes f. The brakes f extend from the fixed pins g to the
rods c.
Consequently when a person, in the act of pulling the truck, depresses
the handle a, the said handle, acting as a lever, raises the band f out of contact
with the bosses e.
Upon releasing the handle the springs h depress the rod c
and so automatically apply the brakes.
In Figure 3 is shewn an arrangement of our invention, wherein we constitute
the handle a a lever of the second order and wherein we utilize the weight of the
handle a (which in some cases may be more weighty than usual) as the means
whereby the brakes are applied. This we do by attaching the free ends of the
band brakes f to pins i upon the handle a. In this case the handle a is
arranged at such a height that when a person grasps it in order to propel the
truck he naturally raises it, and, using the handle as a lever of the second
order, he thus releases the band f. When it is released, the handle by its own
weight tightens the band f around the bosses e and so automatically applies the
brakes.
It will be seen that our invention provides means whereby a railway platform
truck or like hand waggon is automatically braked when the handle by which
such waggon is propelled is released, so that when unattended the waggon is
still under control and cannot run away and whereby the brakes are released
simultaneously with the grasping of the handle by the person about to use the
truck.
Having now 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:-
The employment on a truck of the type herein referred to of band brakes f
adapted to be applied around bosses on the front wheels of such a truck when
the propelling handle thereof is released, substantially as herein described with
reference to the annexed drawings.
