Improvements in and relating to Spring Wheels for Vehicles.
I, GEORGE THOMAS LINK, of Willow Cottages, Staplehurst, in the County of
Kent, Engineer and Machinist, do hereby declare the nature of this invention
to be as follows:-
"
In the Specification of the invention patented by me April 4th 1893 num-
bered 6930, I have described certain improvements in spring wheels for heavy-
wheeled vehicles such as traction engines and the like, whereby the weight
carried by the wheels is more evenly counterbalanced or distributed to the
various parts of the vehicle, and so avoiding the "jur" and shaking experienced
with wheels in which the spokes are a fixture with the wheel rim or felloes.
Now, in accordance with my present invention, in order to produce a spring
wheel adapted for "light" vehicles of every description, including motor cars,
and so forth, I dispense with the use of the blocks cast into steel plates, so secured
that they may be easily taken out when worn and fresli ones inserted, all as
described in the Specification herein before identified, and numbered 6930 of
the year 1893, and instead thereof, the wheel spokes at the outer end, simply
take, into or "play" in recesses or pockets" formed in the wheel rim or
felloes, but without coming into contact with the inside of the sole of the
wheel rim.

COMPLETE SPECIFICATION.
improvements in and relating to Spring Wheels for Vehicles.
T, GEORGE THOMAS LINK, of Willow Cottages, Staplehurst, in the County of
Kent, Engineer and Machinist, 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 : —
In the Specification of the invention patented to me April 4th 1893 Num-
ber 6930; I have described and shewn certain improvements in spring wheels
for heavy vehicles such as traction engines and which ensure that the weight
carried by the wheels, is more evenly balanced or distributed to the various
parts of the vehicle than had theretofore been obtainable, and so avoiding the
jarring, jolting and shaking experienced with wheels in which the spokes are
fixed rigidly into the felloes of the rim of the wheel.
Now in accordance with my present invention, in order to produce a spring
wheel adapted more especially for the lighter class of vehicles relatively to
those above referred to, I proceed as follows, namely; whilst I still retain the
employment of diagonally arranged coiled springs disposed between the spokes
of the wheel substantially as set forth in the Specification of my invention
No. 6930 of 1893; dispense with the use of the blocks cast into steel plates
so secured that they may be easily taken out when worn and fresh ones inserted,

all as described in the said Specification of my invention of prior date herein-
before indentified; and, in lieu thereof, the wheel spokes at the outer end,
take into recesses or "pockets" formed in the felloes of the wheel rim. That
is to say, the spokes are free to play or plunge in said recesses or pockets
but are not allowed to come in contact or touch" with the inside of the sole
of the wheel rim. This latter may be of the usual type; or, it may, to ensure
additional lightness, be made up of a series of segments of inverted Tirons;.
under which latter modification, the ends of the spokes would be formed with
a bifurcated bearing-block piece which would take over and be free to play
between, the vertical member of the 1 iron of the wheel rim but without touch-
ing the bottom member of said iron (inverted T iron).
In the accompanying sheet of drawings illustrative of my said invention
Figure is a side elevation of my improved wheel, two only, of the springs
fitted to the spokes and rim being shewn, the positions of the others being
indicated by the dotted lines. Figure 2 is a cross section, to a larger scale,
of the rim and a portion of one of the spokes. Figure 3 is a cross section, of
a modified arrangement of wheel and spoke adapted to ensure additional light-
ness; and Figure 4 is a side elevation of same.
In the drawings, a are the springs arranged and fitted to the spokes bin a
manner similar to that described in my former specification above referred to
and identified; a¹ are bolts or pins for securing the outer ends of the springs
.to the rim c. The outer ends of the spokes are reduced at-b¹ and enter recesses d
which may either be formed in the woodwork or other material' forming the
rim, or may be constructed by means of flanges or cheeks of metal e forming
the sides of the recesses; and which may be made in one with the ring f fixed to
the inner circumference of the rim, and serving as a guide to the parts b.
Sufficient space is left between the outer ends of the spokes and the bottom of
the said recesses to permit of their outer, lineal motion without coming into
contact with the latter.
In the modification shewn in Figures 3 and the rim is constructed of in-
verted iron in segments, the outer ends of the spokes h are formed with
the bifurcated recessed block or member h, the two sides of which take over
and play upon the vertical member of the inverted T iron rim. The said
sides of the blocks h¹ are preferably recessed and fitted with steel plates which
serve as sliding bearing surfaces between the blocks and the vertical flange
of the rim, and prevent lateral play between them. These plates may be re-
moved when worn and fresh ones placed in position in the recessed blocks.
Amongst the various classes of vehicles (apart from wheeled vehicles generally
including automobiles) for which my improved spring wheels may, with, great
advantage, be adopted, I may particularise army service ambulances, as the
sufferings of the occupants would be very considerably alleviated owing to
the absence of jolting and shaking when my improved wheels are used. They
may also be used with like advantages in the case of invalid chairs.
Having now particularly described and ascertained the nature of any said
invention and in what manner the same is to be performed I declare that
what I claim is:-
An improved spring wheel for vehicles, in which the spokes are so arranged
and fitted in conjunction with the springs, that the outer ends of the spokes
do not come in contact with the inside of the sole of the rim of the vehicle
wheel, substantially as described and with the objects in view herein set forth.
