My invention 'further relates to the various details inthe construction oi' the Wheel, whereby its general eciency is improved.

The springs employed .in the construction of my improved Wheel are, generally speaking, of the type described in my llatent No. 903,582", dated November 10, 1908; In my improvedwheel the springs of the type mentioned serve to increase theelastieity' of the Wheel to such an extent as to practically take the place of a pneumatic tire, and doing this they are much more economical on account of the cheapness of the material employed in their construction, and of the fact that springs of this typemay weer indelinitely before becoming. useless.A As described 'in the patent mentioned, the springs in question comprise a pair of ribbons each provided with convolutions disposed `closely togetller in groups, the groups being separated by Wide intervals, the ribbons beingq generally parallel with each other and so isposed that a group of convolutions of each ribbon meet an interval between groups of convolutions of the other ribbon. By this arrangement the ribbons occupy `two distint planes, the ribbons crossing back and forth from one plane to the other. In seeking a manner for applying. springs of this type to my new wheel, I. provide several parte, the shapes of which are somewhat nn- Specification of Letters Eatent.

Wheel applied; Fig. 2 isa view partly in plan and partly in section, .showing how the springs are mounted and how the outer part of the Wheel has, Within certain limits, freedom of'movement relatively7 to the inner part thereof; Fig. 3 is a plan view of the outer member of the Wheel casing and felly of thewheel; Fig. i is a section upon the line 1--4 of Fig. looking in the direction of the arrow; Fig. 5 is a section upon the line 5-5 of Fig. 6, showing the inner member of the Wheel casing; and Fig. 6 is a planviewof .the inner member of the Wheel casing.

The outer member 7 of the casing' is provided u'ith a rounded portion 7 and With an annular sunken portion 8 for holding the tire 8. The outer member is further provided with annular danl es 9, 10, projecting inwardly, and with circu ar depressions 11, as will be understood fromFigs. 3 and 4. The outer member .7 is stillfurther provided with an annular flange 12 oi comparatively small and extending inwardly. The inner member 18 is provided with an annular flange 14 and with depressions 15, these depressions mating the depressions 11 of the outer member 7. further provided with an annular iange 16 mating the annular flange 1Q.v of the outer The outer member 7 and the uner member 13 are provided with bolt holes 17, 18 for'securing the outer and inner members to ether by aid o' bolts 19 and nuts 20, as will be understood from Figs. 1 and 2. The axle is shown at 21 and is provided with a. nut Q2 for retaining the Wheel upon it. rlhe hub is shown at Q3 and is provided With flanges 24. Disposed intermediate these lianges are spokes .Ztheldtherein by aid of bolts- 25.

y portions "34, which constitute a continuation 'of the convolutions 29, are disposed 1n the two general planes parallel with each other.

j depressions.

g respective planes.

`These convolutions encircle the' bolts 19 which hold together the inner and outer members 'of the wheel casing and are large enough to allow considerable movement between the rim 27 and forcing any part of any convolutionl into direct engagement with the bolt which it encircles. ./As the bosses 28 project into the 11 and 15 of the casing, and as the depressions are of much greaterdiamf eter than the bosses, so that the bosses have l considerable play in the general directionf of the plane of the wheel, the casinglias considerable freedom of movement relatively] .to the rim 27.

The tire S which is made of rubber or fiber, merely takes up wear upon'the outer member of the casing. The axle 2l has, bythe arrangement above described, considerable freedom of movement relatively to the casing as a Whole, and this desirable feature is attained without allowing distortion oi any part ot' the casing or. of any| movable part relatively to the casing, eX-; cept such distortion as vis due to the parts l moving normally in their predetermined l Having thus described my invention, I
