socket being preferably of semispherical
form or contour, as illustrated by Fig. 6.
The spring units are applied by having the
outer catch or hook extremities 15 thereof
5 fitted in the seats or recesses 11 which pro-
vide spaces relatively to the spring band 9
against the outer side of which and over the
opposite side edges the said hooks or catches
15 firmly engage. The spring units are dis-
10 posed in alternation relatively to the oppo-
site sides of the tread organization or unit,
or so that the outer catch or hook extremity
15 of one unit will engage with one side of
the tread organization or unit or the spring
15 band 9 and one of the recesses 11, and the
next spring unit will have its similar outer
catch or hook extremity 15 in engagement
with the opposite side of the spring band
and fit in the adjacent seat or recess 11.
20 When the outer catch extremities of the
spring units are arranged as just described,
it will be seen that they serve to prevent lat-
eral as well as longitudinal shifting move-
ment of the tread organization or unit, and
25 by shieldirng the outer catch or hook extremi-
ties of the spring units within the seats 11,
wear or deterioration of the solid tread
member 12 is prevented, and, furthermore,
the said outer extremities of the spring units
30 are given a very positive securement. The.
outer catches or hooks 15 of the spring units
may be easily assembled in secured relation
to the tread organization or unit 8, or be
separated from said latter unit, and anyone
35 of these spring units may be removed and
replaced by another similar spring unit
when found necessary without disorganiz-
ing or detaching the remaining units or dis-
mantling the entire wheel. The disk 5 has
40 its outer or peripheral edge laterally bent
as at 18 to provide a reinforce for or to
stiffen the said outer edge of the disk, and
at a suitable distance inwardly from the lat-
erally bent or flanged outer edge of the disk
45 sockets 19 are formed in circular alinement
fully around the disk and in alternation, or,
the sockets open outwardly in a reverse-man-
ner in regular sequence around the disk so
as to provide for cooperation with the sock-
50 ets 17 at the inner extremities of the spring
units 13 and 14. The sockets 19 of the disk
5 are formed by indenting the'disk alter-
nately in reverse directions, and the said
sockets 19 are of the same dimensions as the
55 sockets 17 of the spring units and are also
semispherical. In assembling and connect-
ing the spring units relatively to the disk,
the inner socket extremities 17 of the units
are drawn outward from the normal posi-
60 tion shown in Fig. 6 to the dotted line' posi-
tion shown in the same figure until they
aline with or are disposed over the sockets
19, each spring unit being reversed in alter-
nation to 'bring its socket 17 in proper as-
65 sembling relation with the correspondingsocket 19 of the disk. Between the sockets
17 of the springs and the sockets 19 of the
disk antifrictional balls or similar devices
20 are interposed and serve to movably as-
sociate the sockets of the spring units and 70
disk in such manner that separation or dis-
jointure of the inner extremities of the
spring units relatively to the sockets of the
disk is prevented and at the same time the
springs are disposed for loose reciprocating ,
action, or so that there may be a relative re-
ciprocation or sliding movement by the disk
and spring units, and, furthermore, lateral
and torsional movements are provided for
by the association of the spring units and 80
disk as specified.
By arranging the spring units 13 and 14
in alternation as explained and shown in the
drawings, accidental separation of the said
units from the disk and the tread organiza- 85
tion or unit will be prevented in view of
the fact that when the tire organization is
subjected to weight pressure, shocks and
jars, or to lateral stress movements, the said
spring units will pull inwardly across and g0
within the confines of the tread unit close to
the spring band 9, and, as a consequence,
the inward pulling stresses on the outer ex-
tremities of the spring units or the hooks 15
will be increased relatively to the tread unit 95
and particularly the spring band 9. The
free reciprocation or sliding movement of
the inner spring extremities relatively to
the disk through the provision of the co-
operating sockets in the respective parts and 100
the antifrictional balls or analogous de-
vices 20 in engagement with the said sock-
ets will reduce wear on the interacting parts
to a minimum, and it will be practically im-
possible for the inner extremities of the 105
spring units to become accidentally disen-
gaged or disconnected from the disk. In
addition to the reinforcing or stiffening
structure at the periphery of the disk 5 as
provided by the, flange 18, the said latter 110
flange will also serve as a stop means to en-
gage the inner adjacent part of the tread
organization or unit and limit the compres-
sion when the latter is excessive or extremely
abnormal. 115
It will be seen that the spring units and
disk are operatively and positively con-
nected without the use of bolts, rivets or
other devices that might have a tendency to
structurally deteriorate the several parts or 120
reduce the strength thereof, and, likewise,
the spring units are assembled with the
tread organization or unit in a manner
which will entirely obviate the necessity of
using penetrating fastening means. 'More- 125
over, the improved wheel is reduced in cost
of manufacture in view of the simplicity of
associating the disk with the spring units
and the tread organization or unit, and at
the same time the advantages of a resilient 130
