PROVISIONAL SPECIFICATION.
Improvements in and relating to the Construction of Wheels for
Velocipedes and other Light Vehicles.
I ARTHUR COMINGS HIDE, of 23 West Street, Battersea, in the County of
Surrey, Manager of Works, do hereby declare the nature of this invention to be
as follows:-
:-
My invention relates to a further improvement in the construction of wheels
made out of discs of sheet metal, and it has for its object, increased rigidity and
lightness without materially increasing the wind resistance.
My present invention is applicable to all types of wheels in which discs of sheet
metal are used as substitutes for spokes, though it is particularly adapted to be
used in combination with the improved construction of wheel set forth in my prior
Patent No. 8395 of 1891.
My present invention consists in stamping three or more pieces out of each disc
of metal and in so blocking or pressing in the edges of the holes so made, that when
the discs are placed together to form the wheel the said edges meet and are fixed
together by folding or sweating or by both in combination. The solid parts of the
discs therefore form large tubular spokes, the wheel thereby having greatly increased
strength and rigidity with less weight and offering resistance to the wind not
materially greater than that of a solid disc wheel.
Dated this 11th day of January 1892.

COMPLETE SPECIFICATION.
Improvements in and relating to the Construction of Wheels for
Velocipedes and other Light Vehioles.
I ARTHUR COMINGS HIDE, of 23, West Street, Battersea, in the County of
Surrey, Manager of Works, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
My invention relates to a further improvement in the construction of wheels made
out of discs of sheet metal, and it has for its object, increased rigidity and lightness
without materially increasing the air resistance.
My present invention is applicable to all types of wheels in which discs of sheet
metal are used as substitutes for spokes, though it is particularly adapted to be used
in combination with the improved construction of wheel set forth in my prior
Patent No. 8395 of 1891.
My present invention consists in stamping three or more pieces out of each disc
of metal and in so blocking or pressing in the edges of the holes so made, that when
the discs are placed together to form the wheel the said edges meet and are fixed
together by folding or sweating or by both in combination. The solid parts of the
discs therefore form large tubular spokes, the wheel thereby having greatly
increased strength and rigidity with less weight and offering resistance to the air
not materially greater than that of a solid disc wheel.

page_text: In order that my invention may be fully understood I will more particularly
describe it making reference to the accompanying drawing in which
Figure 1 is a view in sectional elevation of the disc of metal ready to be operated
upon to form one side of the wheel.
Figure 2 is a view in sectional elevation of the said disc stamped, blocked, or
pressed to the desired shape to form one side of the wheel but not having the pieces
cut out of it..
Figures 3 and 4 are views in side and sectional elevation respectively showing
the shaped disc having four holes cut in it.
Figure 5 is a view showing the first operation of fixing two of the said discs
together to form the wheel, and
Figure 6 is a view in sectional elevation showing the completed wheel.
Figure 7 is a view in transverse section on line x, x, Figure 3, and
Figure 8 is a broken view in transverse section showing a modification in the
construction of the rim of the wheel.
Throughout the several views similar parts are marked with like letters of
reference.
In constructing my improved wheel I take two discs of sheet metal A, A, each of
which is stamped, pressed, or blocked into the shape shown by Figure 2 of the
accompanying drawing. I then cut or stamp out of each disc three or more pieces
leaving holes a, a, etc. The holes a, a, etc. in one of the discs are of a smaller size
than those in the other for a purpose that will presently be obvious. I then take
the two discs A, A, and having placed the hub B of the wheel between them, I bend
or press in the edges a', a', etc. of the holes a, a, in the disc having the smaller holes
as shown by Figure 5 of the accompanying drawing, and by another operation turn
the said edges over the edges of the holes in the other disc as shown by Figure 6 of
the accompanying drawing to hold the two discs together. The joints so made are
then preferably sweated as also is the joint of the two discs at the periphery of the
wheel. The rim C'may be made out of the discs A, but it is preferably made in
the manner set forth in my prior Patent No. 8395 of 1891.
Instead of folding the edges of the holes of one disc over those of the other disc
to hold the said discs together, the edges may be simply brought together and
sweated or brazed, or as a modification the edges may be clamped together by a
piece of metal of a channel section spun round the edges of the holes.
By this construction I obtain a wheel which has many advantages over those
constructed according to the known methods.
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 construction of wheel as hereinbefore described and illustrated by
the accompanying drawing
