13 Claims. This invention relates to vehicle wheels and more particularly to pressed metal wheels of the reversible type. v

It is an object of this invention to provide a vwheel having a dished wheel body which is adapted to be mounted on a hub with either face of the wheel body out, whereby to vary the wheel tread of the vehicle on which it is used. Another object of the invention is to provide a wheel of. the character described so constructed that a firm yet resilient bearing on the hub is provided.

I rality of staggeredribs or bosses arranged to ex- A still further object of the invention is the provision of a wheel having stiffening ribs on the wheel body for strengthening the central portion thereof.

These objects and others become more apparent in the following specification when read in connection with the accompanying drawings forming a part of this appli'cation.

In the drawings: Figure 1 is a radial sectional view of a vehicle wheel embodying this invention;

Figure 2 is a fragmentary elevational view 0 the wheel shown in Figure 1;

The boltingon flange is provided with aperturesffor the reception .of bolts or cap screws for demountably securingthe wheel body to the hub, and the apertures are inwardly tapered from both faces of the wheel body. The bosses are arranged with respect to the apertures so that the portions of the bolting on flange surrounding the apertures are spaced from the hub flange in either position of r the wheel body. When the securing bolts are drawn up tightly the aforementioned portions wheel but showing the wheel body reversed from the position shown in Figure 1; 1

' In general the invention contemplates the provision of a pressed metal wheel having a central bolting on portion axially offset to one side of the screws ii. The inner faces of the heads of the cap screws 13 are tapered to form shoulders i4.'

A pressed metal wheel body I5 is provided with a peripheral flange 16 which is permanently secured by means of rivets H to arim I8 of the drop center type. This central portion of the wheel body l5 consists of a radially extending bolting on flange l9 which is offset axially relative struction of the bolting on flange l9, it will be apparent thatthe location of the rim 18 in relation to the flange may be changed by merely reversing the position of the bolting on flange l-S. Figure 1 shows the wheel body in one position, and Figure 3 shows the wheel body in the other position. This arrangement is desirable in industrial and farm machinery where it is desirable to 'vary the tread of the vehicle wheels. It is particularly necessary in the case of cultivating machinery where the rows of plants to be cultivated vary in spacing.

In wheels of the type demountable'at the hub thereshould be some provision for stressing the material surrounding the bolt holes when the wheel body is clamped to the hub in order to to the hub. The cap screws provide a tight connection and prevent the cap screws from working loose. In addition, it is desirable that the central portion of the wheel body be relatively rigid in a radial direction.

' with these objects in view. the bolting on flange of the wheel body is corrugated or-provided with a plurality of alternately oppositely extending bosses 2i! and 2|, and ribs 22. Figure 6, which is a sectional view taken on substantially the bolt circle of the wheel body, discloses the relative positions of the vario bosses and ribs. The ribs 22 have openings 23 herein for the reception of the cap screws i3. and the metal immediately surrounding the apertures 23 is pressed inwardly thereby forming a conical seat 24 of the same inclination as the shoulders H on the cap screws the plane thereof in order to provide for the,

drop center rim 38. The wheel body 3i has a bolting on flange 3| which is offset axially iron:

the peripheral flange 30. I The bolting on flange 33 is provided with a plurality of. bosses which are pressed axially from proper contact between the bolting on flange 39 and the hub flange 3|. The original plane of the bolting on flange is indicated in Figure 10 and 11 at 40. At angularly spaced intervals about the bolting on flange are bosses 4| which are pressed axially away from the original plane of the bolting on flange in one direction. As will be noted particularly from Figure 8, the bosses are I3. When the metal around the openings 23 is v pressed inwardly, as described, to form the seat 2|, a circular protuberance 25 is formed on the opposite side of the wheel. This protuberance is machined about the apertures 23 to provide a seat 2' of the same inclination as the seat 24.

Intermediate each pair of ribs 22 is a boss 2| located intermediate the bolt holes and terminate a short distance away therefrom. These bosses are not exactly flat but are relieved or undercut at 42'whereby to provide two

portions

43 and 44 which are slightly offset from each other inan which is separated from the ribs 22 by a pair of bosses The latter extend in a direction axially opposite to the bosses 2|. It will be noted that the bosses 2ll'extend away from the plane of the bolting on flange II a distance slightly v greater than the extremity of the .protuberances 25, and the bosses 2| extend in the same direction as the ribs 22 but to a slightly greater extent.

. It will be apparent that when the wheel bodY is mounted as in Figure 1, the protuberances 23 will not touchthe hub flange, but the bosses 20 will contact the hub flange. Therefore, when the cap screws l3 are inserted inthe apertures 23 and I2 and threaded home. the bolting on flange I9 is flexeduntil the protuberances 25 contact the hub flange. In other words, the portions of the bolting on flange l9 around the bolt holes 23 are bent slightlyabout the bosses 20 as fulcrums; thereby stressing the flange l8.

Likewise, when the wheel body is mounted as in'Figure a, the bosses' 2| initially contact the hub flange and the ribs 22 are spaced from the hub flange. When the cap screws are threaded home, the bolting on flange is flexed until the ribs 22 contact the hub flange. Consequently, theportions oithe bolting on flange around the holes'23 are bent about the bosses 2| as fulcrums to stress the flange II in that region.

In addition to providing 'a means for stressing the flange iii, the bosses 20 and 2| and ribs 22' stiffen the wheel body in a radial direction-thereby reducing the possibility of springing the wheel and causing it to wobble; I

Figures! to 11 .ustrate amodifled formof the invention. In'general the wheel is theme as that described previously, but it difl'ers somewhat in the configuration of the bolting on flange. The main purpose .of the-two modifications is the same, that is, to provide a reversible wheel body equipped with bosses in order 'togive a resilient between the securing'bolts and theboltingon flange.

e The wheel of Figure'l has the usual hub'j3ll which has a radial flange3| to which the wheel body is secured. The flange 3| is provided with tappedvholes 32 for the reception of cap screws 33. for demountably securing the wheel body 35 33 have tapered shoulders 34.

axial direction. The purpose of this offset will.

appear more fully hereinafter.

Intermediate the bosses 4| and radially" outwardly of the bolt holes the bolting on flange is pressed in a direction opposite to the bosses 4| in order to provide bosses 45. The radially inner edge of the flange 33 is also pressed'in the same direction as the bosses whereby an annular ring 46, which in effect is an additional boss, is formed. The ring 46in, as above stated, pressed in the same direction as the-boss 45. but not quite to the same extent, so that the left hand faces of the ring 46 and the bosses 45, asviewed in Figure I 10, are not quite in the same plane.

the outer face of the flange 3|. Because the facesof'the bosses 45 and the ring 46 are not in the same plane, the bosses 45 will contact the flange 3| before the ring 48 will do so. Consequently,

the bolting on flange is flexed slightly when the cap screws 33 are drawn up tightly. In addition to this flexing of the entire bolting on flange,

there issome flexing of the portion of the flange I immediately surrounding the bolt holes 41, or

in other words, those portions intermediate the bosses 43 and the ring 40.

when the wheel is mounted in the reverse position, as in Figures, the bosses 4| provide the sole contact between the'bolting on flange and the hub flange. When mounting the'wheel body in this position the radially outer portions 43 of the bosses 4| contact thehub flange before the inner portions 44 .and thereby permit aslight amount of flexing of the bolting on-flange as the portions 44 are drawn against the hub flange 3|.

, In'addition to this flexing, there is an additional .The wheel body. 35 is formedfrom pressed metal and has a peripheral flange 33 which is secured by means of rivets 31 to a conventional flexing of the bolting onflange in the portions between the circumferentially spaced bosses 4|.

Theflexing of the bolting on flange, or certain parts thereof, is in a direction axially of the wheel. However, when the wheel body is mounted in one position the wheel body is flexed between radially spaced points. If mounted inthe other position the flexing of the wheel body oc- 'curs between radially spaced points and circumferential]! spaced points.

In Figure 8 the areas of contact between the flanges 3| and 33 are indicated. .When the wheel t of said projections are integral body is mounted as shown in'l igure the bolting on flange 3! contacts the hub flange Ii in the dotted areas A and also at the surface of the ring boss 46. When the wheel body is mounted in the reversed position,or that shown in Figure 9, the flange 39 contacts'flange II in the dotted areas B and C.

It will be evident from the foregoing thatvthe -wheels described herein are capable of being mountedineither of two positions, and that due to the particular formation of the on't'he bolting on flanges the wheel bodies are sprung slightly when they are clamped in place on the hub flange. Therefore, there will be slight possibility of a cap screw working loose in servlce.

Furthermore, the bosses stiflen the wheel in a radial direction, thereby making-a more solid wheel than those without ribs.
