rnrssnn msx wanna Application iiled November 10, 1919, Serial No. 886,814. Renewed June 23, 1922. Serial No. 570,518.

To all whom it may concern: Be it known that I, WILLIAM EnAs'rUs \VILLIAMs, a citizen of the United States, a resident of Chicago, county of Cook and State of Illinois, have invented a new and useful Improvement in Pressed Disk Wheels, of which the following is a specification.

The object of my invention is to make a pressed steel wheel that will be very light,

very rigid, cheaply made and adapted to take a demountable tire of the pneumatic type.

The invention is set forth in the claims.

Reference will be had to the accompanying drawing in which Figure 1 is a front elevation of the wheel.

Figure 2 is a transverse section of one-half of the wheel.

Figure 3 is a detailed section on line 3-3 of Figure 2.

Figure 4.- is a of Figure 2.

In the drawing 1 indicates the hub of an ordinary truck wheel, or in some instances a pleasure type of wheel. On this hub there are formed integrally thecfianges 2 connected across by the ribs 3. The flanges 2 are machined out into the grooves 4, into which the edges of the main disk 5 and the reinforcing disk 6 are turned and terminate in the edges 7 and 8.

The disks 5 and .6 are locked into these gIOOVGS by the pressure rings 9 and 10, which .are pressed into their positions under very detailed section on line 4-4 severe pressure, locking the disks 5 and 6 into the hub flanges 2 in the most secure manner, whereby this connection results in uniting the disks 5 and 6 with nearly the full strength of the metal around the entire circumference of the rings 9 and 10, as relates to both tension and compression strains.

The rings 9 and 10 are secured in place by the bolts 11 against accidental displacement, in the event that the frictional engagement should tend to loosen. I

The disk 5. smooth, near the hub, has an abrupt annular ofl'set at 12 and thence passes outward and, as it nears the rim is curved to form a wide annular offset 16 extending in a direction opposite to that of the offset or shoulder 12, and between the two offsets the diskor web has deep and broad radial corrugations 13. The other disk 6 terminates. peripherally in an annular flange 14 fitting against the shoulder at 12.

and near this flange is secured to the disk.

5 by rivets 15. At the outer margin of the offset 16 the disk extends radially outward to form an annular portionl? at the periphery of which it is turned inward to form an outer rim member 18 having inclined marinforcement, 23, having shoulders 24, to engage the margin 22, and secured to the body of the disk 5 by rivets 26.

The overhanging ofl'setportion 16, 17, -18 of the disk 5 is cut away at one point to form a laterally open notch 32 which permits the ready insertion of an air valve device by lateral movement of the tire and valve stem relatively to the disk. 7 a

The demountable rim 21 is'held in place by means of the wedgering 27, which is clamped in place by a series of blocks 28, which are held in place'by bolts 29 passing through the vertical section 17 of the disk, and with their heads 30 enga ing the blocks 23 as shown. Thus the bloc s 23 not only radially sustain the rim portion 18 of the disk 5, but they also furnish the abutment for the'bolts 29. p

The construction thus shown is a very simple one to make, requiring but a few press 0 rations in forming the main disk, and a ew riveting operations, allin simple arrangements and easily accomplished.

In place of the rivets I may use spot welds if desired.

The fastening of the disks around the hub as described, secures approximately the full strength of the metal in both compression and tension, and is a great desideratum,

The arrangement of the flanges 2 braced across by the ribs 3, permits the disks 5 and 6 to be pressed into the grooves 4 under high pressure, and the cost ,of machining these grooves is very small, and thus taken as a whole I have a very light, very strong, cheap and serviceable wheel by the construction shown.

I have here shown the blocks 23 as beingseparate blocks, the purpose being to avoid an entire enclosure of space by the flanges 16 and 18that form the rim of the'wheel, and further to save weight of the wheel, but I may if I choose, substitute for these individual blocks 23, a ring, more or less of the free itself by being same section as shown for the blocks in Fi re 2. V

y using the blocks, when mud .or other extraneous material is taken on in the cavity between the flan es 16 and 18, it can easily shaken out of the space between the blocks.

The outer appearance of the rim of my wheel, owing to the shape of the horizontal flanges 16 and 18, and the vertical flange 17, simulates the a rance of a wooden felloe with its metal e loe band, as generally used with wooden wheels, and thus is adapted to interchange with the rims and fastenings thereto for use with the wooden wheels, which is a reat desideratum.

What I c aim is 4 1. In a wheel of the class described, a hub provided with flan es adapted to have secured thereto two dis 5 oppositely faced, smooth in their area in the zone surrounding the hub, and joined in a region inter mediate between the hub and the rim, and one disk terminating at this junction and the other disk extending to the rim of the wheel and formed into horizontally arranged rim flanges.

2. In a wheel of the cla$ described, a hub provided with flan es adapted to have secured thereto two dis 5 oppositely faced, -smooth.in their area in the zone surrounding the hub, and joined in a region intermediate between the hub and the rim, and one disk terminatin at this junction and the other disk exten ing to the rim of the wheel and formed into horizontally arranged rim flanges, and provided with stiflening corru- .gation's arranged in'the zone between the rim and the juncture of the two lates.

3. In a wheel of the class descri com-. posed of two disks pressed into form, with one of the disks being smaller. than the other in diameter and arranged to brace each other in a zone around the hub, and with the main disk extending outward to the rim and stiflened in the outer area by radially extending corrugations.

4. In a wheel of the class described made of two disks joined to the hub in difierent planes, and one disk being smaller than the other and the two disks'joined together in a region between thehub and the rim, thus giving a mutuall bracing effect and with the dlsk of the arger diameter extending outward to the rim and formed into horizontally arranged annular flanges forming the rim section of the wheel; with a series of sup rting blocks connectin the outer edge 0 the main rim flange with the web portion of the main disk.

5. In a wheel-bf the class described, a hub and pressed-idisks forming the main body of the wheel and secured to the hub in planes asunder from each other and joined to each other in a region between the hub and the rim, one disk being larger than the other and extending from the hub to the rim and provided with a shoulder intermediately, located between the hub and the rim, and the other disk terminating and abutting at this shoulder and joined to the larger diameter disk at this zone.

6. In a wheel of the class described, a hub and pressed disks formin the main body of the wheel and secure to the hub in planes asunder from each other and joined larger disk outward from the said shoulder to the region of the rim.

7. In a wheel of the class described, a main pressed disk having an annular pressed cavity simulating in outward appearance the felloe and band of a wooden wheel and forming the rim section of the wheel, with a secondary disk bracing the main disk to'the hub from a region intermediately between the rim and'the hub.

'8. In a wheel of the class described, a main pressed disk pressed to simulate in out-ward appearance the ordinary felloe of the wooden wheel on the front edge, with an open space on the rear side and said open spree bridged or supggrted across by suita le supporting mem rs.

9. In a wheel of the' class described, a main disk forming the main body of the wheel and suitably connected to the hub and having its rim portion braced to simulate the appearance of a box or wooden felloe on the front side, and this section reinforced across the felloe region by members on the rear side, and with a secondary smaller disk bracing the main body of the disk to the hub.

10. In a wheel of the class described, a main disk forming the main body of the wheel and suitably connected to the hub and having its rim portion braced to simulate the appearance of a box or wooden felloe on the front side. and this section reinforced across the felloe region by members on the rear side, and with a. secondary smaller disk bracing the main body of the disk to the hub, and with radially alined stiffening corrugations extending inward from the box section in the main disk.

11. In a wheel of the class described, a main disk pressed into a box section simulating on its forward face the rim portion of a wooden wheel, having bracing reinforcement on the rear face forming as it were the other side of the box section, and said reinforcement adapted to take the strain of horizontal bolts used in securing the demountable rim to the wheel and also to share the vertical load of the rim section transmitted to the web section.

12. In. a wheel of the class described, having a pressed box sectional rim and said rim closed in on the inside by a series of spaced blocks forming the other walls of the box section and said blocks secured to the margin ot' the rim on the inside thereof to take direct horizontal pressure and radial pressure by means of an interlocking shoulder between the parts.

13. A pressed wheel disk marginally oil'- set to form an annular felloe-like portion overhanging the body of the disk, and having said portion cut away at one point form ing at that point a forwardly open notch.

14. In a wheel of the class described, a pressed wheel body disk having a rearwardly flanged felloe-like portion laterally overhanging the disk in front of the median plane of the wheel and having the overhanging portion cut away to present a forwardly opening notch.

15. A wheel disk marginally offset to form through the wheel margin within the wedge ring and the ring bridging said aperture.

,16. A pressed Wheel body disk having an annular felloe-like portion laterally overhanging the disk and cut away to allow inserting an air valve device, further having a broad peripheral face provided on one side with a seat for the corresponding side of a rim and bearing at its opposite side a wedge ring affording a seat for the other side of a rim, the marginal portion of the disk having in its outer zone a lateral valve-aperture which is outwardly bridged by said wedge ring.
