UNITE-D STATES CHARLES lr. ERICKSON, or BROOKLYN, NEW YORK.

VEHICLE WHEEL.

Original No. 1,251,358, dated December 25, 1917, Serial No. 151,285, filed February 27, 1917. Application for reissue led December B, 1919.

To all whom it concern:

Be it known that SON, a subject of the King of Sweden, residing at Brooklyn, in the county of Kings and State ot New York, have invented new and useful Vehicle liheels, of which the following isa specification.

This vinvention relates to improvements in vehicle wheels and more `particular-ly to the yresilient non-pneumatic class of wheels.

One object ot'the present inver-tion is to 'eect improvements in the construction of the tire and diaphragms by forming the diaphragms directly with the tire and so that the diaphragms are permanently connected to the tire.

Another object is to provide improved means for moving vthe disks relatively to each other to tension the diaphragms and yto also strengthen and brace the wheel.

Another object is to yeliect in'rprovcments in the construction of 'the hub.

Another object is to e'iq'ect 'improvements in the construction of the tire and to provide the same with non-skid devices.

With the above and other objects in view the invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings Figure 1 is an elevation partly in section of the wheel constructedr and arranged in accordance with my invention.

Figure 2 is a transverse sectional View ot' the same.

Figure 3 is a detailed view of an adjusting bolt.

The hub 1 is adapted to be mounted on an axle in the usual way, is provided at the outer side with a. cap 2 and is provided at the inner side with an outstanding annular ange 3 which is L-shaped in cross section.

l A pair of disks 4, 5 are arranged on the hub, said disks in practice being made of steel or other suitable material. The outer disk 4 has a centrally7 arranged collar 6 through which the hub extends and said disk is mounted for movement on the hub toward and from the outer end thereof. The inner disk 5 is bolted as at 7 to the front side of the flange 3 and said disk is crosssectionally angular as shown and fitted on said flange and is immovable.

The disk 4 has inwardly extending circular seats 8 at a suitable distance apart and I, CHARLES F. Einen- 'seriai No. 343,423.

the disk 5 is provided at points opposite said seats with inwardly extending interiorly threaded tubular portions '9. Adjusting bolts l() connect the disks 4 and 5 and engage the threaded openings of the latter disk. VSaid bolts have stop flanges 11 which bear against the inner sides of the seats 8. The bolts pass through yuinthreaded vopenings in the seats so that said bolts are mounted in the seats for rotation but are retained against longitudinal movement with respect to the disk to which they are rotatably connected, 4such movement being prevented by means of the stop `flanges 11 and lock nuts 12 carried by the bolts 10 and disposed -respectively upon opposite sides of the seats 8.

The -tirel 13 embodies a ybody 14 which may be made of rubber'o'r of 'any other suit able material and the tire is also provided with -a resilient rinror ring' 15 which is emv" bedded therein. Diaphragme 16 which are pliable 'and which may be made of the same fabric -as the tire are formed integrally with the tire and are hence oermanently united thereto and are arrangec at the sides thereof. The diaphragms may be made of one or more pieces of material as desired. The diaphragms have their .inner portions fitted in circumferential annular recesses in the disks and are securely fastened to the disks as by means of rivets 17 or other suitable devices.

By adjusting the outer disk away Jfrom the inner disk, which may be eliected by first loosening the lock nuts 12 and then turning the bolts 1() in the required direction by a wrench, the diaphragms may be tensioned to any extent desired, after which the tension may be decreased by turning the bolts 10 in an opposite direction in which case theI tension already stored or built'up in the diaphragms is sufficient to effect relative movement of the disks 4 and 5 toward each other as will be readily appreciated. The lock nuts when screwed in place effectnally secure the bolts. against casual turning'and hence the desired tension of the diaphragms is maintained. The bolts also ef- Jfectually brace the disks and diaphragms and serve to greatly strengthen the construction of the wheel without interfering with the resilience of the wheel. The diaphragms being flexible serve to absorb shocks received by the wheel and hence relieve the axle from excessive shocks and consequently also the vehicle carried by the aXle. By permanently uniting the diaphragms to the tire the diaphragms are strengthened and moreover the cost of manufacture of the diaphragms and tire is lessened.

The body or outer portion of the tire is provided With an annular circumferential groove 18 and transversely arranged cross bars 19 which are here shown. as integral, and Which serve to prevent skidding.

l/Vhile I have herein shown and described a preferred form of my invention I would have it understood that changes may be made in the form, proportion and construction of the several parts, Without departing from the spirit of my invention and Within the scope of the appended claims.

Having thus described my invention, What I claim is z* l. In a vehicle Wheel of the class described the combination ol a hub having a flange, a disk secured to said flange, a disk mounted on the hub and movable toward and from the lirst-named disk, adjusting bolts connecting said disks at points Without the hub, a tire, and diaphragms united to the sides of the tire and secured to and tensioned by said disks.

2. In a vehicle Wheel of the class described, the combination of a hub, a pair of disks thereon arranged for relative movement, adjusting bolts .connecting said disks, said bolts having threaded engagement With one of the disks and being rotatably connected to the other, means for retaining said adjusting bolts against longitudinal movement vvith respect to the disk to which they are rotatably connected, a tire, and diaphragms united to and extending from the sides of the tire and secured to said disks.

3. In a vehicle wheel oi the class de scribed, the combination of a hub having an outwardly extending annular flange at its inner end, a disk around the hub, secured to said flange and provided at points Without the hub With inwardly extending interiorly threaded tubular portions, an outer disk having a centrally arranged collar through Which the hub extends, said outer disk being mounted for movement on the hub toward and from the inner' disk and being provided with inwardly extending circular seats, a tire, diaphragms united to and-eX tending from the sides of the tire and secured to the disks, bolts connecting the disks and each engaging one of the tubular portions of the inner disk and being connected to one of the seats of the outer disk for rotation and means for retaining said bolts against longitudinal movement with respect to the disk to which they are rotatably con` nected, said means being in the form of stop flanges and lock nuts carried by said bolts on opposite sides respectively of said seats.

In testimony whereof I afx my signature.

CHARLES F. ERICKSON.
