PROVISIONAL SPECIFICATION.
Improvements in or connected with Trucks or Trolleys, more particu-
larly Intended for the Conveyance of Luggage on Railway Station
Platforms, and the like.
I, HENRY THOMAS SHADRACK, of 650, Boyd Road, Victoria Docks, London, E.,
Gentleman, do hereby declare the nature of this invention to be as follows:
-
This invention relates to improvements in trucks or trolleys more particularly
intended for the conveyance of luggage on railway station platforms and the like,
the object being to provide such trucks or trolleys with simple braking apparatus
that can be quickly and automatically applied on depressing or releasing a handle,
said braking apparatus preventing such trucks from being accidentally set in
motion, while it also prevents, to a great extent, their use by unauthorized
persons.
In carrying this invention into practical effect, I provide a longitudinal lever
arranged horizontally beneath the frame-work of the truck, and pivoted at its
forward end. To this lever is pivotally connected two arms, one upon each side
of the pivotal point of said lever, said arms extending approximately at right
angles from same and being fitted or furnished with brake blocks designed to be
brought into contact with the sides of the front pair of wheels, upon the free end or
extremity of the aforesaid horizontal lever being brought over to one side, and
which is automatically effected upon the free end of the lever being released from a
suitable catch, by means of a sufficiently powerful spiral spring, secured at one end
to the side of the frame of the truck or trolley, while the other extremity is
secured within a longitudinal slot formed in the aforesaid horizontal lever, said
slot allowing of the spiral spring being suitably adjusted as required.

I, HENRY THOMAS SHADRACK, of 650, Boyd Road, Victoria Docks, London, E.,
Gentleman, do hereby declare the nature of this invention and in what manner the
Q71

page_text: same is to be performed, to be particularly described and ascertained in and by the
following statement:-
This invention relates to improvements in trucks or trolleys more particularly
intended for the conveyance of luggage on railway station platforms and the like,
the object being to provide such trucks or trolleys with simple braking apparatus
that can be quickly and automatically applied on depressing or releasing a handle,
said braking apparatus preventing such trucks from being accidentally set in
motion, while it also prevents, to a great extent their use by unauthorized
persons.
"
In order that my invention may be fully understood, I will now proceed to
describe same with reference to the accompanying drawings in which Fig. 1 is an
underside plan of the framework of a truck fitted with my improved form of brake
apparatus.
Fig. 2 is a similar view of a modified form of this invention.
Fig. 3 is a section on line of Fig. 1 and,
Fig. 4 is an elevation of the end of a truck showing a suitable form of catch
as used in connection with Fig. 1.
All views are shown in the reverse position or upside down.
According to this invention and as shown in Figs. 1, 3 and 4, I provide a
longitudinal lever a arranged horizontally beneath the framework of the truck and
pivoted at b to the bracket c. To this lever are pivotally connected two arms ef,
one upon each side of the pivotal point b, said arms extending from same and being
fitted with brake blocks designed to be brought into contact with the sides or
solid centre portion h (Fig. 3) of the wheels w upon the free end or extremity k
of the lever a being pulled over in the direction indicated by the arrow and
which is automatically effected by the spring as soon as the said extremity k is
released from the catch m.
In the normal position of the lever it is retained by the catch m as shown (Fig. 4)
the braking apparatus being then in the position shown in Fig. 1, while upon the
extremity of the lever being relased from the indent of the said catch mit
is automatically drawn over by the spring bringing the brake blocks g against the
sides or solid central portions of the wheels.
The spiral spring 7 is secured at one extremity to the side of the truck and at the
other to a block n sliding within the slot o which allows of the spring being adjusted
when required.
In the modified form of the invention shown at Fig. 2, the essential difference
consists in applying the brake blocks to the outer peripheries of the wheels, and
according to this form of my invention I arrange a lever 7 pivoted at 21 and two
arms pivoted at q¹ in such a manner as to be free to turn, one extremity of
each arm q being furnished with a brake block g, while the other extremity q² is
suitably connected with the lever p.
I further provide a cross lever ŕ pivoted as shown, operated by a sliding arm s
and spring and in such a manner that upon the sliding arms being released
from any suitable catch retaining it in position the spring draws forward the
arm of the lever thereby depressing the arm 2 and drawing back at the same
time the lever p which operates the arms qq in such a manner as to apply the brake
blocks g to the wheels w.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. The improved braking apparatus for trucks comprising a horizontal pivoted
lever such as a having side arms e and f pivotally connected thereto and fitted with
brake blocks g designed to be brought against the sides or solid central portions h
of the wheels, by the action of a spring substantially as herein described and
shown with reference to Figs. 1, 3 and 4 of the accompanying drawings and for
the purposes specified.

page_text: 2/. The modified form of the invention comprising the arrangement of a rod or
lever 2, pivoted arms q, connected at their extremities thereto, and fitted with
brake blocks g, a pivoted cross lever r, sliding arms and an operating spring v,
and a suitable catch of any kind for retaining the arm s in the forward position
when the brake is not in use, substantially as herein described and shown with
reference to Fig. 2 of the accompanying drawings, and for the purposes specified.
3/. The improvements in or connected with trucks or trolleys, substantially as
herein described and shown with reference to the accompanying drawings, and for
the purposes specified.
