hooks 27, the clips being curved outwardly,
as at 28, to give ample space between the in-
ner extremities thereof for the application
and practical operation of plate springs 29
5 of the form particularly shown by Figs. 9
and 10. Each plate spring 29 has inwardly
bent terminal hooks 30 at opposite ends, the
center of the spring being increased in
width, as at 31, and from which opposite
10 portions of the spring taper toward the
hooks 30. At the center each spring is
formed with an opening 32 therethrough to
fit over one of the stems 16 of one of the studs
15, and to hold each spring in applied posi-
15 tion on its stem 16 a securing head or elon-
gated nut 33 is used and applied over the
stein 16, said head or nut having an inner
convex side or face 34 adjacent to the outer
convex edge 14 of the rim 13 and also a
20 transverse opening 35 to coincide with the
opening 17 through the stem 16 for the pur-
pose of receiving a removable cotter pin or
analogous device 36. It will be observed
that the center of each spring 29 is held be-
25 tween two convex surfaces, and the object
of this arrangement is to cause the said
spring at the center to gradually follow the
curvature of these opposing faces and pre-
vent fracture of the spring at this point by
30 avoiding engagement thereof with flat sur-
faces or angular projections that would ob-
viously tend to injure the central attached
portion of the spring. These opposed con-
vex faces, and especially the convex edge
35 14 of the rim 13, provide for a regular bend-
ing operation of each spring in a curved
form, and to, carry out the same advantage
the inner portions of the terminal hooks 27
of the clips 25 have regular convex edges
40 37 over which the adjacent portions of the
extremities of each spring may bend with-
out liability of fracture.
Each clip 25 has an overhanging shoulder
or beveled seat 38 at its outer end which
45 opens outwardly and the seats of the op-
posed clips at opposite sides of the tire are
engaged by correspondingly shaped flanges
or hook members 39 at the ends of con-
necting plates 40 which are resilient and
50 serve to tie the outer ends of the clips and
also provide a support for a continuous
spring band 41 extending completely around
the tire, and applied over the said spring
band, connecting plates 40, and the outer
55 ends of the clips 25 or the heads 26, is a
resilient tread 42 preferably constructed of
rubber or rubber composition and provided
with a seat 43 to receive the said spring
band 41 and plates 40, as clearly shown by
6o Fig. 4. Each clip 25 near its outer end or
head 26 has an inwardly projecting rib or
boss 44 extending partially over the width
thereof and between guard bosses or flanges
45, as shown particularly by Fig. 5. Be-
CS tween the ribs 44 and the bosses or flanges45 of each pair of opposed clips, auxiliary
springs 46 are interposed and comprise a se-
ries .of springs 47 of equal length arranged
in groups and bowed in opposite directions,
the ends of the groups of springs having 70
recesses 48 to fit over the ribs 44, the springs
being held against sidewise shifting move-
ment by the bosses or guard flanges 45, as
shown by Fig. 5. These auxiliary springs
operate to maintain the parts of the tire 75
in connected relation or in operative asso-
ciation and also give to the tire material
resilience or yielding action or augment the
tire in its sensitive operation. Moreover.
it will be seen that the present tire has a so
part thereof assembled without the use of
connecting bolts or rivets, the clips 25 be-
ing connected through the springs 29 which
always have a tendency to draw inwardly
on the inner extremities of said clips. 85
When the springs 29 are disconnected, the
clips may be readily separated and release
the auxiliary springs 46, and the assem-
blage of the latter springs may be readily
accomplished in view of the fact that there 90
are no fastening devices therefor, said
springs being simply slipped in place be-
tween the clips in engagement with the
ribs 44.
When weight pressure is exerted on the 95
wheel and tire embodying the features of
the invention, the springs 29 will be
bowed downwardly or toward the auxiliary
springs 46, and the tendency of this action
of the springs 29 is to draw inwardly on 100
the inner extremities of the clips 25, but
this inward drawing action is materially
resisted by the auxiliary springs 46 which
expand and contract between the clips and
also by the resilient action of the spring 105
band 41 and the plates 40 through the pres-
sure on the tread 42. It will therefore be
seen that a multiplied resilient operation
ensues in the tire when the latter is !sub-
jected to weight pressure and this action is 110
distributed over the length of the tire or
taken up by the elements of the tire in op-
posite directions relatively to the portion
of the tire subjected to the greatest pres-
sure, as the clips are free to compensate or 115
accommodate themselves to this distribut-
ing resilient action of the tire. The springs
29 may be readily applied and removed
without dismantling the remaining portion
of the tire and all of the parts of the tire 120
can be easily assembled, and it will be seen
that the several parts are of similar form
and can all be constructed from the same
pattern with material economy in the cost
of manufacture. 125
What is claimed is:
1. A tire comprising a removable rim, a
series of fiat springs connected to the rim, a
plurality of opposed clips having their in-
ner extremities engaged by the ends of the 1302
