Improvements in Wheels.
I, FELIX KLINGELHÖFER, of 32 Clanricarde Gardens, Notting Hill, in the
County of London, Mechanical Engineer, do hereby declare the nature of this
invention to be as follows:-
a
My invention relates to improvements in wheels, which consists of a hub with a
zig zag collar, constructed of any metallic substance and if preferable enclosing
nave of wood or other suitable material, and into which the spokes are fitted. The
zig zag collar is formed on its outer periphery into a number of projections that
constitute sockets for the reception of the ends of the spokes. The lower inner
portion of the sockets is made taper, for reasons to be hereafter explained. Each
spoke is constructed in two parts; in order to effect this, a number of pieces of flat
steel are first corrugated longitudinally, leaving a flange on each side of the
corrugation and are then bent round a template so as to form an isosceles triangle
with the corners rounded.
The free ends of the segments thus formed are then inserted into the taper
sockets on the hub, and are then pressed home. It will thus be seen that two
adjacent sides of two adjacent segments will form one spoke, while the base of the
isosceles triangle will form a segmental portion of the rim of the wheel. The
Hanges which are formed on each side of the longitudinal corrugations with the
corrugated portion will constitute a cylindrical spoke with lateral ribs. A wood
spoke may if preferable be inserted inside the metallic spoke. The sockets on the
hub are slotted half their depth on each side so as to receive the flanges and thus
afford additional support and rigidity to the spokes. The ribbed or flanged sides
of the spokes may, if desired, be rivetted or otherwise secured together so as to
prevent them from separating. The flanges do not extend to the extreme ends of
the segments, and the opposing faces of the ends of the corrugations are slightly
bevelled so as to enable the adjacent segments to be forced closely together at the
bottom of the taper sockets by hollow steel plugs. When the segments are in
position in their sockets, all their bases forming the periphery are surrounded by a
corrugated rim to receive an india-rubber tyre. The corrugated rim may be
constructed in one piece. Upon the inner surface of the rim is formed semi-
circular projections or beads which are intended to fit into the depression or
corresponding corrugations of the periphery of the combined segments. The rim
is bent to the requisite circular form and is then placed round the wheel so as to
encircle the combined segments, and compressing it into the peripheral depressions.
its two ends are then joined together in any suitable and practical manner. If
necessary the small triangular spaces between the rounded corners of the
segments and the rim may be filled by small chocks composed of any suitable
material.
All the segments when placed together will form a rough circle the adjacent
sides of the segments forming tubular flanged spokes of the wheel. The ends of
the segments are then introduced into the zig zag sockets on the hub and pressed
home, and the taper portion of the socket causes the space between the bevelled
and other edges to lie close together.
In order to afford additional support and rigidity to the spokes, the sockets are
slotted half their depth on each side, the lateral ribs or flanges entering these
slots.
In order to prevent the flanges of the spokes from separating or buckling in the
centre, between the hub and the rim, the flanges of the spokes may be secured

page_text: together by rivetting or otherwise. The rim may be filled in with wood, papier-
mache or other suitable material, and will preferably be constructed in one piece,
the ends being secured together in any suitable manner. The inner surface of the
filling is formed into corrugated projections, so arranged that it shall fit into the
depression or grooves in the segmental portions of the metallic rim.
If preferable an india rubber band may be inserted in the corrugated rim for the
purpose of fixing an additional wood rim or felly to receive the usual iron tyre.
It will be understood that I do not particularly bind myself to construct the
wheel in the manner herein described, as the materials shapes and parts may be
varied in many ways within the scope of my invention.

Improvements in Wheels.
I, FELIX KLINGELHÖFER, of 32 Clanricarde Gardens, Notting Hill, in the
County of London, Mechanical 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:
My invention relates to improvements in wheels, which consists of a metallic hub
with a zig zag socketed collar, and into which corrugated metallic spokes fit,
surrounded by a corrugated sheet steel rim.
The object of my invention is to provide a rigid wheel constructed mostly of
corrugated sheet steel of a light and strong description for every class of
vehicle.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a front elevation of a wheel with an india rubber tyre.
Fig. 2, is a side elevation of Fig. 1.
Fig. 3, is a front elevation of a wheel with a metallic tyre.
Fig. 4, is a section of the rim of Fig. 3.
Fig. 5, is a longitudinal section of half the hub and a part of the fitting of a
spoke.
Fig. 6, is a section on line C. D.
Fig. 7, is a section on line A. B.
Fig. 8, is one fourth of the plan of the circumference of the socketed collar on
the hub.
Fig. 9, is a half section of a metallic spoke.
Fig. 10, is a section of an india rubber tyre fitted to a rim.
Parts of the figures are drawn to an enlarged scale and are broken off for
convenience.
Similar letters refer to similar parts throughout the several views.
The zig zag collar a is formed on its outer periphery into a number of slotted
sockets for the reception of 'the ends of the spokes. The lower inner portions of
the sockets b are made straight as indicated by dotted lines for reasons to be
bereafter explained. Each spoke cis constructed in two parts; in order to effect
this, & number of pieces of flat steel are first corrugated longitudinally, leaving a
flange d on-each side of the corrugations and are then-bent round a template so as
to form an isosceles triangle with the corners rounded: The free ends of the
segments thus formed are inserted into the taper sockets on the hub f, and are
then pressed home. It will thus be seen that two adjacent sides of two adjacent
segments will form one spoke, while the base of the isosceles triangle will form a

page_text: segmental portion of the rim of the wheel. The flanges d which are forined on
each side of the longitudinal corrugations with the corrugated portion will
constitute a cylindrical spoke c with lateral ribs. A wood spoke m may if
preferable be inserted inside the metallic spoke as in Fig. 6. The sockets on the
hub fare slotted to a suitable depth on each side so as to receive the flanges d and
thus afford additional support and rigidity to the spokes c. End of each spoke
rests on an india rubber cushion f which is let in the wood hub. When the segments.
are in position in their sockets, all their bases forming the periphery are surrounded.
by a corrugated rim g to receive an india-rubber tyre i. The corrugated rim g
may be constructed in one piece. Upon the inner surface of the rim are formed
semi-circular projections or beads which are intended to fit into the depressions or
corresponding corrugations of the periphery of the combined segments. The
rim g is bent to the requisite circular form and is then placed rount the wheel so
as to encircle the combined segments, and compressed into the peripheral
depressions; its two ends are then joined together in any suitable and practical
manner. If necessary the small triangular spaces k between the rounded corners
of the segments and the rim g may be filled by small chocks composed of any
suitable material.
All the segments when placed together will form a rough circle the adjacent
sides of the segments forming tubular flanged spokes of the wheel. The ends of
the segments are then introduced into the zig zag sockets on the hub f and pressed
home.
In order to prevent the flanges d of the spokes from separating or buckling in
the centre, between the hub and the rim g, the flanges of the spokes may be
secured together by overlapping. The rim-o as in Fig. 4, may be filled in with a
felly n of wood, papier-mache or other suitable material, and will preferably be
constructed in one piece in order to receive a metallic tyre l, the inner surface of
the fellyn is formed into corrugated projections, so arranged that it shall fit into
the depression or grooves in the segmental portions of the metallic rim.
The hub is lined in the inside with wood lining for the purpose of enlarging
the opening to suit any size axle box.
It will be understood that I do not particularly bind myself to construct the
wheel in the manner herein described, as the materials shapes and parts may be
varied in many ways within the scope of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, declare that what I
claim is :-
1. In vehicle wheels, the combination of the slotted sockets arranged peripherally
on a zig zag collar around a metallic hub, substantially as described and for the
purpose specified.
2. In vehicle wheels, the combination of the segments each segment being
composed of a longitudinally corrugated plate of sheet steel so arranged that the
adjacent sides of the adjacent segments forms flanged spokes with wood fillings,
substantially as described.
3. In vehicle wheels, the combination of a projecting felly and iron tyre on the
inner surface of the corrugated rim as in Fig. 4, substantially as described and for
the purpose specified.
4. In vehicle wheels, the combination of the spokes and rim constructed of
corrugated sheet steel, substantially as herein described and according to the
accompanying drawing.
