Engineer, (communicated to me from abroad by Walter Abbott Wood of Hoosick
Falls, State of New York, United States of America,) do hereby declare the nature
of this invention to be as follows:-
The object of this invention is an improved construction of wheels for agricultural
inachines, vehicles and other purposes by which a considerable saving of both
labour and material in their manufacture is effected, combined with the greatest
amount of strength.
According to this invention the hub which receives the spokes is made in two
parts or discs of malleable iron, steel or any other suitable metal one part or disc
is made with a box cast upon it, which has a hole large enough to receive the axle
bearing. The other part is a disc without a hub, but has a hole large enough to
allow it to slip over the hub on the other disc. The spokes are made oval in form
in their cross section for a portion of their length at their larger end and of
the right size to fit into recesses or oval shaped forms one half of which are
formed in or on one disc and one half in or on the other. The large end of the
spokes abut against the hub on one disc, the ends being made in proper shape to
fit the same when the spokes are inserted and the other disc then slid upon the
hub of the first disc until it comes in contact with the spokes, the recesses in or
on one disc corresponding with those on the other disc, enclosing or fitting over
the spokes and when in this position the two discs or parts are fastened firmly
together by bolts and nuts.
The outer and smaller ends of the spokes are screw threaded and pass through
holes in the rim of the wheel and receive the gripping lugs which are screwed on
to their projecting ends. They also have nuts threaded on the interior surface
of the rim for the purpose of producing an end strain between the hub and rim
through the spokes.

page_text: When the wheel is required to be smooth on the exterior surface of the rim the
nuts can be screwed up against the interior of the rim and the outside ends
of the holes in the rim counter sunk and the small ends of the spokes rivetted
down in them.
The rim of the wheel (as made for a Harvesting Machine) is made of a thin
plate of rolled steel with preferably four ribs or webs on the inner surface to give
it strength, one on each side of where the spokes enter and one on each edge.
The rim is bent and rivetted together.
The bearing for the axle passes through the hub and is furnished with arms or
branches with holes and is bolted to the discs or flanges of the hub.
When the wheel is to be used on a Harvesting or other machine where it is
necessary to impart motion from the wheel to other working parts, one portion
of the hub is made long enough to receive the hub of the gear wheel or other
driving mechanism.

I, WILLIAM MCINTYRE CRANSTON of 36 Worship Street, Middlesex, Agricultural
Engineer, do hereby declare the nature of this invention which has been communi-
cated to me from abroad by Walter Abbott Wood of Hoosick Falls, State of New
York, United States of America and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:—
The object of this invention, is an improved construction of wheels for agricultural
machines, vehicles, and other purposes by which a considerable saving of both
labour and material in their manufacture is effected, combined with the greatest
amount of strength.
According to this invention, which will be understood by reference to the annexed
drawings, the hub A which receives the spokes B B is made in two parts, or discs
(as shown at Figures 1 and 2) of malleable iron, steel, or any other suitable metal,
one part or disc C is made with a box D cast upon it, which has a hole F large
enough to receive the axle bearing. The other part (Figure 2) is a disc F¹ without
a box, but has a hole G large enough to allow it to slip over the hub or box D on
the other disc C. The spokes B B are made oval in form in their cross section for
a portion of their length at their larger end B¹ B' and of the right size to fit into
recesses, or oval shaped forms H H one half of which are formed in or on one disc
and one half in or on the other. The large end B' B¹ of the spokes abut against
the hub D on the disc C, the ends being made in proper shape to fit the same when.
the spokes B B are inserted and the other disc F1 then slid upon the hub D of the
disc C until it comes in contact with the spokes B B as shown at Figure 3, the
recesses H H in or on one disc corresponding with those on the other disc, enclosing
or fitting over the spokes and when in this position the two discs or parts are
fastened firmly together by bolts and nuts J J.
The outer and smaller ends of the spokes B B are screw threaded and pass
through holes in the rim K of the wheel and receive the gripping lugs L L which
are screwed on to their projecting ends. as shown at Figure 4 which is a perspective
view of a wheel ready to receive the axle bearing. They also have nuts M M
threaded on the interior surface N of the rim for the purpose of producing an end
strain between the hub A and rim K through the spokes B B.
When the wheel is required to be smooth on the exterior surface of the rim K
the nuts M M can be screwed up against the interior N of the rim and the outside
ends of the holes in the rim counter sunk and the small ends of the spokes rivetted
down in them as represented at P Figure 5.
The rim K of the wheel (as made for a Harvesting Machine) is made of a thin
plate of rolled steel with preferably four ribs or webs Q on the inner surface N to
give it strength, one on each side of where the spokes enter and one on each edge.
The rim is bent and rivetted together.
In Figure 5 the bearing R for the axle passes through the hub A and is furnished
with arms or branches S S with holes and is bolted to the discs, or flanges C and F¹
of the bub A

page_text: When the wheel is to be used on a Harvesting, or other machine, where it is
necessary to impart motion from the wheel to other working parts, one portion of
the hub is made long enough to receive the hub of the gear wheel or other driving
mechanism which may be attached in any convenient manner, immediately behind
the hub A as shown at T in Figure 5 or in any suitable position, according to the
machino to which it is adapted.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :-
The improved construction of wheels for vehicles, specially those used for
agricultural, harvesting, and other agricultural purposes as set forth.
