Improvements in Wheels for Vehicles.
I, REGINALD HADDAN, of the Firm of Herbert Haddan and Co. of
18, Buckingham Street, Strand, W.C. London, Patent Agent, do hereby declare
the nature of this invention a communication to me from abroad by Edward Gustav
Schleicher, of Stamford, State of Connecticut, United States of America,
Manufacturer, and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :—
This invention consists in a wheel comprising a metallic web corrugated radially
and provided on its periphery with a wheel rim, a metal tube provided on its outer
surface with screw threads, two nuts adapted to engage the screw threads of the
metal tube and a corrugated disk interposed between the web and one of said nuts.
The web of the wheel may also be constructed of two corrugated plates. The
wheel rim consists of two sections which are secured to opposite sides of the web
and the outer ends of which form elastic jaws for the reception of a hollow elastic
tire with a projection extending beyond the jaws and forming the tread of the
wheel.
In the accompanying drawing
Figure 1 represents a transverse vertical section of a wheel, the web of which
consists of a single corrugated metal plate, the plane of section being indicated by
the line Fig. 2.
Figure 2 is a sectional face view, the plane of section being indicated by the
line y y Fig. 1.
Figure 3 is an inside face view of one of the nuts on a larger scale than the
previous figures.
Figure 4 is an inside face view of the corrugated disk.
Figure 5 is a horizontal section in the plane z z Fig. 1, the section being drawn
on the same scale as Figs. 3 & 4.
Figure 6 is a transverse vertical section of the wheel the web of which is
composed of two corrugated metal plates.
Figure 7 is a horizontal section in the plane z z¹ Fig. 6, on the same scale as
Figs. 3 and 4.
Figure 8 is a section on the rim of the wheel and of the hollow rubber tire on a
larger scale than the previous figures.
The hub of the wheel consists of a metal tube A which is provided on its outer
surface with a screw thread 10 and on its inner surface with recesses 11 which
serve to retain the lining 12 which is formed of an antifriction metal such as Babbit
metal and which can be produced by casting the antifriction metal round the
axle 13.
The screw threads 10 on the metal tube A engage two nuts 14, 15 and a disk or
washer 16 is placed loosely upon said tube and serves together with the nuts to
connect the web B with the hub. This web consists of a corrugated metal plate
which is provided with a central hole large enough to pass upon the tube A, the
form of the corrugations being indicated in Figure 5.
i..
The inner. face of the nut 14 is provided with a series of radiating grooves 17
alternating with projections 18 (Fig. 3) and the inner face of the disk 16 (which is
bored out to fit loosely upon the metal tube A) is provided with radiating
grooves 19 and projections 20 (Fig. 4) and these grooves and projections are so
proportioned, that when the outer portion of the corrugated metal plate B is placed
against the inner face of the nut 14 and the disk 16 is forced inward by the nut 15,
the corrugations of the plate B are firmly clamped between the nut 14 and the

page_text: $
disk 16 as indicated in Fig. 5 and a firm connection is effected between the web B
and the hub of the wheel.
On the circumference of the web B is formed or secured a rim C of any suitable
form. In the example represented by the drawing the rim is made of such a form,
that it is adapted to receive an elastic tire of any suitable construction.
In the example represented in Figs. 6 and 7 the web B consists of two corrugated
metal plates which engage the inner faces. of the out 14 and the disk 16 in the
manner shown in Fig. 7. As indicated in Figs. 1 and 6 the corrugations of the
web B increase in depth from the circumference towards the hub so as to impart to
the wheel a graceful appearance.
The novel construction of the rim C and of the elastic tire T is illustrated in
Figure 8. The rim C consists of two jaws 21, 22 which are fastened to the opposite
sides of the web B by screws or rivets 23 and which are made of sheet metal so
that they have a certain elasticity and that their free ends can slightly open and
close. In cross-section each of the jaws forms about three-eighths of a circle
leaving an open space 24 of about 90 degrees through which the elastic tire T is
forced in. This tire is made of soft vulcanized india-rubber and it is provided
with a bore 25 which extends throughout its entire body and which is of sufficient
size or diameter to insure the required elasticity, so that it can be compressed
sufficiently to permit its introduction through the open space 24 of the rim C and
that when it has been crowded in through this space, it will expand and fit the
interior of the rim C snugly. From the hollow or tubular body of the tire extends
a solid rib 26 through the open space 24 and a short distance beyond the edges of
this open space.
The curved circumference of the rib 26 forms the tread of the
wheel and its sides 27 are rectilinear and parallel to a line 28 drawn through the
centre of the wheel and through the centre of the tubular body of the tire (Figs. 2
and 8). When the wheel revolves on the ground, the rib 26 is forced inward so as
to compress the tubular body of the tire and the jaws 21, 22 expand sufficiently to
permit the sides of the rib to move in and out without sustaining any injury.
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. A wheel comprising a metallic web corrugated radially and provided at its
periphery with a wheel rim, a metal tube provided on its outer surface with screw
threads, two nuts adapted to engage the screw threads of the metal tube and a
'corrugated disk interposed between the web and one of said nuts substantially as
described.
;
2. A wheel composed of the metal tube A provided on its outer surface with
screw threads, the nuts 14, 15 adapted to engage these screw threads, the nut 14
being provided with grooves 17 and projections 18, the disk 16 fitting loosely upon
the metal tube A and provided with grooves 19 and projections 20 and the web B
provided with corrugations adapted to engage the grooves and projections on the
nut 14 and the disk 16 substantially as described.
3. The combination with the web B of a rim C composed of two elastic segmental
jaws 21, 22 leaving an open space 24 of about 90 degrees between their free
edges and a tubular elastic tire T provided with a solid rib 26 substantially as
described.
