This invention relates to disk wheels and has special reference, to that class ofdouble disk vehicle wheels provided with demountable tire supporting rims.

My invention airns to provide a double disk wheel body wherein the center hub supporting portionioi" the body is firmly eonnectedto a hub and the. disks of the body to provide a r igid body portion-at the hub; i

The. disks are formed with annular inwardly lged portionsso that the bodies of the disirs intersect the plane of rotation and peripheries of saiddisks are formed withfi anges adapted for supporting a deet red-e rini. The disk flanges have a configuration hich necessitates "forcing a a r ewa rim inw dly t e a g and"p rovision1s made to, prevent circumf eren tial e ijp ing' of the den iountable rim on the s n s,

fhfly inventi n 'further aims to provide a double disk wheel wherein the disks have rim supporting flanges with the'rperipheral portions of the disks articulated by rim holding ilasteners which be easily and quickly p acedin position to "prevent an outward displacement of the the supporting rim during rotation oi; the wheel.

' My invention further aims to provide a disk vehicle wheel p ossessing the requisite degree and at the saine'tiine affording a degreeof resiliency which will son-- tributetosafe and easy riding of a vehicle body supported by wheels in aceordance with thi in e e- My invention further aims to provide a wheel body composed of inner and outer disks having peripheral flanges with said fiangesdisposed softhat the flange of the inner disk may be somewhat contracted or drawn intoa rim, and" the flange of the outer disk crowded onto the inner disk so that the the outer disk is somewhat spread and adapted to cooperate with the flange, of th e" innei disk in clamping a riin or otheristi'iic'tureon said disks; doiible llisk wlieel willfbe liereiiiai ter specifically described and then claimed, and referenee new be had to the drawings,

The wheel bodyis composedof an outer disk 1 and an inner disk 2 and these disks have central portions disposed in parallelism and provided with oo-axial flanged openings with the annular flanges 23 and 1; confronting each other so that said flanges may bear upon a hub 5 provided with a brake drum 6, a fired inner plate. or head 7 and a deengaging the outer iaoeot the inner disk 2 and a flange 11 engaging the inner faceot theouter disk 1. The filler member 9 spaces the disks 1 and 2 apart and is adapted to hold said disks against the heads 7 and 8 when said heads are connected by a plurality of equipped bolts 12 extending through said heads", the disks 1 and 2, the filler member 9 and the brake drum 6.

In addition to the filler member 9 bracing the inner wall of the outer. disk 1, said filler member bears on theflange 3 otthe outer diskland braces said flange by reason or the bolts 12 extending through-thefiller memher. It is prefer-ableto have the periphery otthe fillenmelnber 9 meet the inner face of the outer disk 1 adjacentthe peripheral edge's'o f the head 8 and inturn theiou-ter Th inner and-o ter disks. are p esided with annular inwardly bulged portions 13 which bring the disks into closer proximity to each other and imparts a compound curve, in cross section, to said disks, so that said disks will intersect parallel planes of wheel rotation. With these disks bulged or dished a degree of resiliency is imparted to the same and clearance provided at the outer disk 1 for a pneumatic tire filling tube or connection 1 1 which is adapted to extend through an opening 15 in the outer disk.

The periphery of the inner disk 2 terminates in an annular flange 16 and said flange is not exactly disposed at a right angle to the plane of the disk2, but is slightly at an angle to said disk so that the free edge of the flange 16 will have a diameter slightly greater than where the flange joins the disk. This is in order that a demountable rim 17 may be placed on the flange 16 and cause compression or flexure of the flange 16 as the rim 17 is forcedinwardly with the binding action between the rim 17 and the flange 16 preventing excessive inward movement and displacement of the rim 17 relative to the double disk body of the wheel. This is best shown in Figs. 10 and 11 where the flange 16 has its angularity exaggerated and if the flange is not retracted as fully as shown in Fig. 2, then the rim 17 will contact with the edge of the flange 16 and obtain a firm purchase thereon. In drawing the inner disk into the rim or forcing the rim on to the flange 16, it may happen that the edges of the flange 16 will protrude from the inner side of the rim and the rim stick and seat on the flange 16 some place between the outer edges of the flange and the body of the disk 13. 1

The outer disk 1 also has a peripheral flange 18 similar in many respects to the flange 16 but maintained in spaced relation to the flange 16 except at depressed portions 19 of said flange where extensions 20 abut the disk 2 contiguous to the flange 16 thereof. The extensions 20 of the flange 18 may ride up on to the curved portion o the flange 16, at its juncturewith the disk 13 and in so doing tend to distend the flange 18 whereby it may cooperate with the flange 16 in clamping and supporting the rim 17. The rim 17 is of the split type having its split ends 21 transversely slitted, as at 22 and inwardly pressed to form seats 23 for a connecting bar 24 flush with the outer wall of the rim l7, and fixed to one end of the rim by rivets 25 and attached to the opposite end of the rim by a screw bolt 26. This manner of connecting the split ends of the rim permitsof said rim being easily mounted in an inflated pneumatic tire or outer casing 27 which has the filling tube or connection 24 extending through an opening '28 of the rim l7 and a notch or slot 29 in the flange 18. This flange also p ovi ed with notchorrecess movement of the demountable rim 17 on the disk flanges 16 and 18, even though these flanges do not frictionally hold the demountable rim against inward movement the bead 31 will do so. The head 31 is adapted to be engaged by fasteners comprising bead and disk engaging clips33 provided with lips 3 1 extending between the bead 31 and the outer disk 1 to extend into the depressions 19 of the flange 18. The clips 33v may be held in position by nut equipped bolts 35 non-rotatably held by the disk- 2 and extending through openings 36 of the outer disk 1 and through the clips 33 with nuts 27 on the outer ends of said bolts. After the rim is placed on the disks the fasteners may be employed for drawing the flange '16 into the rim, causing distention of the flange 18, and firm anchoring of the rim on the disk bodyof the wheel.

It is thought that the manner of constructing the wheel and the advantages gained by such construction will be apparent without further description, and while in the drawings there is illustrated av preferred embodiment of my invention, it is to be understood that the structural elements are susceptible to suchvariations and modifications as-fall within the scope of the appended claims.

What I- claim is 1. In a disk wheel, a" double disk body composed of inner and outer disks, peripheral flanges carried by said inner and outer disks and extending in the same direction relative to said disks, a demountable rim seated on the flanges of said disks, said flanges being in proximity to each other and having a combined width approximatelythe width of said rim, and rim fasteners carried by said inner and outer disks adjacent the flanges thereof. 7

2. A disk wheel as called for in claim 1, wherein said demountable rim has an annular bead adapted to abut the outer disk at the base of its flange which disk has its flange provided with depressed portions to receive portions of said rim fasteners.

3. A disk wheelas called for in claim 1, I

wherein said rim fasteners include clips adapted to engage between said rim and said outer disk and extend onto the flange of the outer disk. 1 I I i 4. In a disk Wheel, a double .disk body having peripheral flanges with the flange of one of said disks provided with a depressed portion, and a rim having anjpternal abutment thereon, the depressed portion of said disk engaging the periphery of the other of said disks, whereby outward pressure of the depressed flange is exerted against the inner wall of said rim, said depressed portion also serving to receive said abutment and prevent circumferential creeping of said rim on said disks.

5.- In a dish wheel, a rim, inner and outer disks having peripheral flanges adapted to clamp the inner wall of the rim, the flange of the inner disk being retracted when the rim is placed thereon, the flange of the outer disk being distended by abutting the inner disk, and means for connecting said disks to retain the rim on the flanges of said disks.

6. A disk wheel comprising a rim, inner and outer disks, and flanges on said disks engaging said rim, one of said flanges being distended by engagement with the other flange.

7. In a disk wheel, a rim, inner and outer disks, flanges on said disks, one of said flanges adapted to be retracted and the other flange distended with both of said flanges cooperating in retaining said rim on said flanges, and means connecting said disks.

8. In a disk wheel, a rim, an outer disk therein, an inner disk adapted to be shifted towards said outer disk and caused to clamp said rim by portions of the outer disk being distended against said rim, and means for clamping said disks together with the rim thereon.

9. In a disk wheel, a rim, inner and outer disks having peripheral flanges both extending in the same direction and affording a seat for said rim, and extensions of the flange of said outer disk abutting the periphery of said inner disk and spacing the peripheral portions of said disks apart.

In testimony whereof I aiflX my signature.
