PROVISIONAL SPECIFICATION:
Improved Spring Wheel for Locomotives and Heavy Waggons or
Carriages.
I GEORGE THOMAS LINK of Staplehurst, Kent, Engine Proprietor do hereby
declare the nature of this invention to be as follows:-
This invention has for its object the construction of an improved spring wheel for
locomotives, and heavy waggons or carriages whereby the weight carried by the
wheels is more equally counterbalanced or distributed to the various parts of
the same.
In accordance with my invention and with reference to the Specification of my
Patent No. 2333 dated 9th February 1889, I attach one extremity of parallel
coil or spiral springs to the double spokes at a point midway between the periphery
and the centre of the wheel, the other extremity of said springs being attached to
blocks rivetted to the inside of the sole of the wheel.

I provide for the adjustment of the above mentioned springs so as to produce a
greater or lesser tension, in the following manner. At the point in the double
spokes midway between the periphery and the centre of the wheel I place an
ordinary
hinge joint adapted to the spokes by a pin ; and, in the
block rivetted to the sole of the wheel I also place a similar joint fixed thereto by
means similar to those above described :-formed in one piece with each part of the
"fork" or "hinge" joint is a screw and on this screw runs a nut, the blocks at the
ends of the springs are tapped to receive the screws above referred to, the threads
on these screws are cut right and left handed respectively so that instead of
withdrawing the aforesaid pin and removing the block as in the Specification of my
Patent No. 2333, dated 9th February 1889, it is only necessary to either turn the
springs to the right or left as may be required for either expanding or contracting
the tension of the wheel.
On the ends of the spokes near the sole of the wheel I cast blocks, these blocks
do not touch the inside of the sole of the wheel but enough space is allowed for the
movement according to the tension or compression of the various springs, said
tension or compression being caused by the nature of the road over which the wheel
passes. In order to prevent the sideways shaking of the blocks cast to the ends of
the spokes I dovetail them into steel plates, thus filling up the transverse space,
these plates are so secured that they may easily be taken out when worn and fresh
ones inserted.
.
I arrange the exact positions of attaching the springs both to the double spokes
and to-the-blocks so that the distance between the centre of the wheel and the pin,
and from the pin to the blocks-and-from the pin to the periphery of the wheel are
all equal, and further, each spring can be removed-and-replaced without interfering
with other parts and springs.

I, GEORGE THOMAS LINK, of Staplehurst, Kent, Engine Proprietor, 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 has for its object the construction of an improved spring wheel for
locomotives, and heavy waggons or carriages, whereby the weight carried by the
wheels, is more equally counter-balanced or distributed to the various parts
of same.
And in order that my invention may be more fully understood I have appended
the accompanying sheet of drawings in which
Figure represents a side elevational view of a wheel, partly in section,
constructed in accordance with my invention and
Figure 2, an elevational view to an enlarged scale of one of the coiled or spiral
springs hereinafter more particularly referred to.
In accordance with my invention and with reference to the Specification of my
Patent No. 2333 dated 9th February 1889. I attach one extremity of parallel coil
or spiral springs a to the double spokes bat a point midway between the periphery
and the centre of the wheel, the other extremity of said springs being attached to
blocks c rivetted to the inside of the sole of the wheel.

I provide for the adjustment of the above mentioned springs, so as to produce a
greater or lesser tension, in the following manner; at the point of the double
spokes b midway between the periphery, and the centre of the wheel, I place an
ordinary "fork or hinge" joint d adapted to the spokes by a pin; and, in the
block c rivetted to the sole of the wheel I also place a similar joint, fixed thereto by
means similar to those above described. Forined in oue piece with each part
of the "fork or "hinge" joint is a screw; the blocks formed at the ends of the
springs are tapped to receive the screws above referred to, the threads on these
screws are cut right and left handed respectively, so that instead of withdrawing the
aforesaid pin and removing the block cas in the Specification of my Patent
No. 2333 dated 9th February 1889, it is only necessary to either turn the springs
to the right or, left as may be required for either expanding or contracting the
tension of the wheel.

On the ends of the spokes 6 near the sole of the wheel, I cast blocks g, these
blocks do not touch the inside of the sole of the wheel but enough space is allowed
for the movement according to the tension or compression of the various springs a,
said tension or compression being caused by the nature of the road over which the
wheel passes.
In order to prevent the sideways shaking of the blocks g cast to the
ends of the spokes 6 I dovetail them into steel plates, thus filling up the transverse
space, these plates are so secured that they may easily be taken out when worn and
fresh ones inserted.
I arrange the exact positions of attaching the springs a both to the double
spokes band to the blocks c so that the distance between the centre of the wheel
and the pin to the blocks, and from the pin to the periphery of the wheel are all
equal, and further, each spring can be removed and replaced without interfering
with other parts and springs.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is: :-
The improved spring wheel for locomotives and heavy waggons or carriages,

page_text: arranged and constructed substantially as herein set forth and shown in the
accompanying sheet of drawings.
