and other Vehicles.
I, HENRY MARTYN RYDER, of 54, Charlotte Road, Edgbaston, Birmingham,
in the County of Warwick, Electro-Metallurgist, do hereby declare the nature
of this invention to be as follows:-
This invention relates to railway trolleys, lorries, & other vehicles, & the object
thereof is to overcome the dangers arising from the starting, or running away,
of these trolleys when unattended and not under control.
To overcome these dangers I place in practice a self acting brake, operating
upon the front or bogie wheels, & freed by handle of trolley.

"
This brake is always on when the trolley is unattended, and is "off" only
when the handle of trolley is grasped & pulled or pushed down.
The moment the handle is released the brake firmly grips the wheels and
prevents any further motion.
Referring to Fig. 1, (A) is the bogie, and (B) the wooden axle beam as at
present used. (C) the wheels. (1)) the brake which is fixed to an iron bar (E).
From this bar (E) run two rods (F) going under, or through axle beam, which
is grooved out or pierced to receive them. The two rods (F) end in heads (G).
Between the heads (G) and axle beam are spiral springs which cause the brake
to firmly grasp the wheels. (H) is the iron rod, as at present used, to support
handle of trolley. From the centre of bar (E) another rod (J) runs under or
through axle beam, & connects with handle of trolley. This rod (J) is hinged
at (K) & (L) and is also pinned to (H).
By this means, when handle bar of trolley is pulled, or pushed down, leverage
is obtained from (H) to (K) & the brake is pushed "off."
As soon as handle is liberated the brake pressure is immediately applied
automatically, by pressure of springs, & remains so until handle of trolley is
again pulled, or pushed, down.
If preferred a single carriage spring may be used, instead of spiral springs
as already described. I have shewn this arrangement in Fig. 2.
The carriage
spring is bolted to (J) which passes through it.
Fig. 3 & Fig. 4 are side elevations of Figs. 1 & 2.
It will be apparent that this spring or springs may be of any desired form,
or construction, without departing from the spirit of my invention, which
consists of a self acting brake, freed by the action of the handle of trolley, sub-
stantially as shewn & described in this specification, & the drawings accompany-
ing it.
Datad this 10th day of September 1898.

Improvements in Means for Controlling Railway Trolleys, Lorries,
and other Vehicles.
I, HENRY MARTYN RYDER, of 54, Charlotte Road, Edgbaston, Birmingham,
in the County of Warwick, Electro-Metallurgist, 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 railway trolleys, lorries, & other vehicles, & the object
thereof is to overcome the dangers arising from the starting, or running away
of these vehicles when unattended & not under control.
In the drawings-reference being made to those filed with my Provisional
Specification I place in practice a self acting brake, or brakes, operating upon
the front, bogie or other wheels, & freed by the action of the handle bar of
trolley.

"
This brake is always on when the trolley is unattended & is "off" only
when the handle of trolley is grasped, & pulled or pushed down.
The moment the handle is released the brake or brakes firmly grasp the wheel
& prevent any further motion.
Referring to Fig. 1, (A) is the bogie & (B) the wooden axle beam as at present
used. (C) the wheels. (D) the brakes, which are fixed to an iron or wooden
bar (E).
From this bar (E) run two rods (F) going under or through the axle-beam,
which is grooved out or pierced to receive them.
The two rods (F) end in heads (G).
Between the heads (G) & the axle beam are spiral springs which cause the
brakes to firmly grasp the wheels.
(H) is the iron rod as at present used to support handle of trolley.
From the centre or bar (E) another rod (J) runs under or through the axle
beam & connects with handle of trolley.
The rod (J) is pinned to (H) & is hinged at (K) & (L).
By this means when handle of trolley is pulled or pushed down leverage is
obtained from (H) to (K) & the brake is pushed "off."
As soon as handle bar is liberated brake pressure is immediately applied
automatically by pressure of springs, & the trolley stops.
If preferred a single carriage spring may be used instead of the spiral springs
already described.
I have shewn this arrangement in Fig. 2. The carriage spring is bolted to (J)
which passes through it.
This arrangement can also be applied to a trolley, whose front wheels are
castors, by fixing the brake to the rear wheels.
Figs. (3) & (4) are side elevations of Figs. (1) & (2).
It will be apparent that this spring or springs may be of any desired form
or construction without departing from the spirit of my invention.
Having now particularly described and ascertained the nature of my said
invention, & in what manner the same is to be performed I declare that what
I claim is:-
1. A self acting brake or brakes, operating upon the front, bogie, or other

page_text: wheels, & freed by the action of the handle bar of trolley substantially as shewn
& described in this specification & the drawings filed with my Provisional Speci-
fication.
