similar Vehicles,
We, JAMES SIMPSON BOLLAND WRIGLEY and FREDERICK WRIGLEY, both of 413,
Park Road, Oldham, in the County of Lancaster, Engineers, and JAMES STOTT, uf
2, Camberwell Street, Oldham, aforesaid, Engineer, do hereby declare the nature
of this invention to be as follows:-
This invention relates to means for automatically putting a bruke on the wheels
of railway platform trucks or trolleys when the latter are not under the direct
control of the porter or other person in charge thereof, but the same invention
is equally applicable to similar hand trucks or vehicles.
We mount upon the forecarriage or the transverse wooden bar which carries
the front wheel and handle, a pair of brackets (one at each side) extending to the
edge of and not far from the said wheels. Each bracket carries a brake lever, the
short end of which is provided with a brake shoe and brake block of suitable
material.
The other end of cach brake lever is prolonged inwards towards the centre of
the transverse wooden bar aforesaid, where it is slotted and engages with a pin
on a central rod which passes through (or above or below) and across the wooden
bar or forecarriage.
A spring at the back of the latter adjustable by a suitable nut and screw on the
rod last named normally holds the brake on the front wheels by pushing back the
long ends of the break levers.
The front end of the rod however is connected to a small crank lever (carried
by the fore carriage) the other end of which is connected by a link or otherwise
with the end of the handle which normally hangs down and allows the rod to be
pushed back by the aforesaid spring.
As Boon however as any one raises the handle to move the vehicle the link or
like device connected thereto pulls the cranked lever and draws back the spring
rod, withdrawing the brakes from the wheels, until the handle is released again
and falls, allowing the spring to put on the brakes again.

WO, JAMES SIMPSON BOLLAND WRIGLEY and FREDERICK WRIGLEY, both of 413,
Park Road, Oldham, in the County of Lancaster, Engineers, and JAMES STOTT, Jf
2, Camberwell Street, Oldham, aforesaid, Engineer, do hereby declare the nature
of this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement:
-
This invention relates to means for automatically putting a brake on the wheels
of railway platform trucks or trolleys when the latter are not under the direct
control of the porter or other person in charge thereof, but the same invention
is equally applicable to similar trucks or vehicles.
We mount upon the forecarriage or the transvorse wooden bar which carries
the front wheel and handle, a pair of brackets (one at each side) extending to the
edge of and not far from the said wheels. Each bracket carries a brake lever, the
short end of which is provided with a brake shoe and brake block of suitable
material.
The other end of each brake lever is prolonged inwards towards the centre of
the transverse wooden bar aforesaid where it is slotted and engages with a pin
on a central rod which passes through (or above or below) and across the wooden
bar or fore-carriage.
A spring at the back of the latter adjustable by a suitable nut and screw on the
rod last named normally holds the brakes on the front wheels by pushing back the
long ends of the break levers.
The front end of the rod however is connected to a small crank lever (carried
by the fore-carriage) the other end of which is connected by a link or otherwise
with the end of the handle which normally hangs down and allows the rod to be
pushed back by the aforesaid spring.
As soon however as any one raises the handle to move the vehicle the link or
like device connected thereto pulls the cranked lever and draws back the spring
rod, withdrawing the brakes from the wheels, until the handle is released again
and falls, allowing the spring to put on the brakes again.
It will be evident that the brakes may be applied to special wheels or pulleys
fixed to or forming part of or otherwise rotating with the wheels of the vehicles."
The annexed drawings illustrate clearly how our invention may be applied to
a railway platform trolley or truck and from these its application to similar vehicles
is self evident.
Fig. 1 is an elevation of the bogie end of the truck.
Fig. 2 is an underneath plan thereof.
Figs. 3 and 4 are similar views of a modification hereafter described.
On the drawings a is the body of the truck, and b is the forecarriage or trans-
verse swivelling bar which carries the front wheels 61 and handle e of which the
upper end hangs down when the truck is not in use.
is the link aoove described connecting the part el of the handle to the small
cranked levere carried by a bracket f fixed on the bar b; the lever e is connected
to the rod g, normally held back by the spring g', this spring g' pressing against
the adjustable nut and abutting against the bar 6 as shown at Figs. 2 and 4.
The inner or rear end of the rod 9 is connected to the two levers h h carried by
the bracket i fixed to the bar or forcarriage b, and the other or shorter end of
the levers hh are brake shoes or blocks kk.
These brakes act either directly on the wheels 6¹¹ as seen at Figs. 1 and 2

page_text: or indirectly by their application to special wheels or pulleys 66 fixed to or
forming part of or otherwise rotating with the wheels bb as seen at Figs. 3 and 4.
In this case the wheels or pulleys 66 and the brakes & may be roughened or
toothed as shewn to render the grip or brake action more effectual.
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 combination of the hanging end of the handle of a trolley or truck of the
kind above described with a link, lever, spring rod, and brake levers mounted and
operating substantially as herein before set forth.
Dated this 18th day of March 1899.
