PROVISIONAL SPECIFICATION.
An Improved Method of Making Gear and other Wheels.
I, JOHN RICHARDSON, of the City of Lincoln, Engineer, do hereby declare the
nature of this invention to be as follows:--
In carrying out this invention, I make the boss or hub of a wheel in one or more
pieces and with flanges.
Instead of the usual arms, I secure discs of wrought steel plate by bolts or rivets
to the flanges upon the boss.
These discs may be flat or dished according to the circumstances, and may be of
any number according to the width of the wheel required. The rim of the wheel
is composed of a number of rings placed side by side, the discs before mentioned
going between these rings, and bolted or rivetted thereto.
These rings may be further subdivided, so that each ring may be in halves or
quarters so as to reduce their length and size. The intersections of the joints
may overlap each other, so that not more than one joint shall be in the same line
transversely.
By this means a wheel of any size or strength may be built up of small pieces,
and in small weights, and erected with perfect truth on arrival at its destination.
In the case of gear or toothed wheels, after all is built up, as above described,
the teeth are cut in the circumference by suitable mechanism, thus all the advan-
tages of a strong solid wheel are secured, with, at the same time, the facility for
dividing into small pieces.

COMPLETE SPECIFICATION.
An Improved Method of Making Gear and other Wheels.
I, JOHN RICHARDSON, of the City of Lincoln, Engineer, 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 relates to an improved method of making gear and other
wheels.
In carrying out this invention, I make the boss or hub of a wheel in one or
more pieces and with flanges and instead of the usual arms, I secure discs of
wrought steel plate by bolts or rivets to the flanges upon the boss. These discs
may be flat or dished according to the circumstances, and may be of any number
according to the width of the wheel required. The rim of the wheel is composed
of a number of rings placed side by side and may be in sections, the discs before
mentioned going between these rings, and bolted or rivetted thereto.
These rings may be further subdivided, so that each ring may be in halves or
quarters so as to reduce their length and size. The intersections of the joints may
overlap each other so that not more than one joint shall be in the same line
transversely.
The annexed drawings show a spur gear wheel constructed according to my
invention, which is however applicable to all kinds of wheels.

page_text: A. Boss or hub shown as made of a single casting.
B, B. Flanges slightly tapered.
C, C, C, C. Plates constituting discs attached respectively to the flanges B, B.
D, D. Strips or overlaps of the sectional disc plates by which they can be
bolted, or otherwise secured in position to one another.
.
E, E, E. Rim rings between which the outer edges or ends of the disc plates
lodge.
F, F, F. Bolts through rim rings and plate C, C, C, C.
It will be observed by the sectional portion of Figure 2, that the middle ring E
is annularly recessed on each side, the depth of the recesses corresponding to the
thickness of the plates C, C, in order that the surfaces may when bolted close home
be in actual and firm contact.
The peripheries of the rim rings E, E, E, may be plain or scored according to
the purpose for which the wheel is intended and in the case of gear or toothed
wheels, after all is built up as above described, the teeth are cut in the circum-
ference by suitable mechanism, thus all the advantages of a strong solid wheel are
secured, with, at the same time, the facility for dividing into small pieces.
By this means, a wheel of any size or strength may be built up of small
pieces and in small weights, and erected with perfect truth on arrival at its
destination.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
-
1. The hereinbefore described method of constructing gear and other wheels,
and as exemplified by the annexed drawings.
2. The building up and the attachments of parts, as described, to constitute a
wheel, and their removal and separation for transportable purposes as herein set
forth.
