METAL DISK WHEEL.

Application filed February 7, 1920. Serial No. 356,848.

. new and useful Improvement in Metal Disk lVheels, of which the following is a specification, reference being had therein to the accompanying drawing.

his invention relates generally to wheels,

and more particularly to a sheet metal disk' wh el, the object being to provide a wheel body composed of a plurality of sheet metal sectors ermanently or detachably connected toa huh structure, and adapted to receive a tire carrying rim either directly upon the disk or through the medium of a fixed rim.

Another object of the invention is to provide a sheet metal disk wheel embodying these characteristics which shall be strong,

and durable, and at the same time simple and easy of construction.

Another object is to provide a wheel constructed in the man r hereinbefore described which shall be ideedingly light and one in which one or mo of the sectors can be removed and replaced in case of damage, and also one in which the disk as a whole can be demounted from the hub.

A still further object is to provide a sheet metal disk wheel which will lend itself to both front and rear hub structures.

With these objects in view, and certain others which will become apparent as the description proceeds, the invention consists in the novel features of construction and in the manner of combinin or arranging them, all of which will be fufiy described hereinafter and set. forth in the appended claims.

In the drawings forming a part of this specification, Fig. 1 is a side elevation of a portion of a rear wheel constructed in accordance with my invention, the brake 'drum being also shown in elevation. Fig. 2 is a sectional view on the line 22 of Fig. 1. Fig. 3 is a detail perspective viewv of one of the sheet metal sectors; and Fig. 4 is a plan view of the blank from which said sec tor is made. Fig. 5 is a diagrammatic view showing the economical manner of cutting the blanks. Fig. 6 is a detail view showing a slightly modified form of sector. Fig. 7 is a detail view-showinga modified form of fixedrim and means for connecting the tire carrying rim thereto. Fig. 8 is a detail sectional viewof one type of hub to which the disk sectors are detachably connected. Fig. 9 is a detail view showing the tire carrying rim attached directly to peripheral portions of the disk sector.

In carrying out my invention I employ a" plurality of sheet metal sectors of such shape that when'assembled they will provide a complete circular disk. Each sector A is formed with radial flanges B, and the arouate flange G, and when the sectors are placed together the radial flanges B will provide a series of strengthening ribs for the disk and the flanges C will provide a circumferential edge or periphery and to this circumferential edge or periphery I may attach a fixed rim D (Fig. 2) also of sheet metal and preferably channeled as shown, the legs of said channeled fixed rim being of different heights, and in practice I prefer to depress the outer-leg of said fixed rim at definite intervals as indicated at D. The fixed rim D is intended to receive thereon the demountable tire-carrying rim E which is preferably formed with an inwardly projecting bead E and also provided with clamping lugs F through which the bolts G pass; and nuts H are arranged upon the ends of said bolts thereby completing the fastening of the demountable tire-carrying rim to the fixed rim, each clamping lug being adapted to engage a depressed portion in the outer leg of the fixed rim. The fixed rim is riveted or otherwise rigidly connected to the circumferential flanges C as indicated'at I in Figs. 1 and 2. Instead of the channeled fixed rim shown in Fig. 2, I may employ an angled fixed rim D riveted to the flanges C and carryingbolts G, the demountable rim E having clamps F which fit over the bolt ends and secured bythe nuts H, as-most clearly shown in Fig. 7. The radial flanges B are preferably made tapering towards their outer ends as shown in order to give the proper dish to the disk as a whole and also provide the maximum strength at the point of attachment to the hub. The hub K is of the usual construction so far as the interior thereof is concerned, but the exterior thereof is formed with a plurality of bosses L which arebored axially as indicated at L and also split or divided axially as indicated at L Each radial flange B is upset near the inner end as indicated at B and when two sectors are placed with their radial flanges together the mating upset or pressed out portions B produce a substantially cylindrical barrel of such size as to fit snugly in the axially bored portion L and the portions of the flanges above and below said upset portions will fit into the split portions L of the hub bosses and the rivets or bolts M are then passed through the hub bosses and sector flanges and secured as most clearly shown in Fig. 2 thereby rigidly connecting the sectors to the hub structure and it will be noted that the brake drum N can be rigidly connected to the wheel body by the same set of bolts or rivets which connect the disk sectors to the hub structure, the outer face of the brake drum being aperture'd to receive the said connecting bolts or rivets. The inner ends of the sector flanges may be tapered or inclined as indicated at B and the hub is formed with a corresponding inclination K in order to make a rigid connection between the said flange and spoke.

This type of disk wheel is capable of being employed as a de-mountable wheel and in this event, the disk will be demounted or detached from the hub. This is accomplished by making the bosses L slightly deeper, and having the ends of the bores L threaded as shown at L so that the ends of the bolts L can be screwed into the same, and in practice I prefer to bore the bosses on a slight taper and shape the portions B accordingly so that they can be easily inserted and removed and when clamped in place by the'bolts will be securely con nected to the hub, but at the same time easily demounted by removing the bolts.

When the disk is detachably or demountably connected to the hub, the fixed rim or felly may be dispensed with and the tire carryin rim 0 attached direct to the peripheral in Fig. 9.

If desired the radial flanges of the sectors may be formed with ribbed portions B which facilitate the welding of said flanges at those points; one sector thus formed being shown in Fig. 6.

A wheel body constructed 'as herein shown and described is light, strong and durable and when painted will have the appearance of a radially ribbed sheet metal disk, and if desired the ribs can be connected to each other by spot welding or riveting and with a rigid connection at the hub and at the periphery an exceptionally strong wheel body will be provided. A valve stem hole O can be provided in one of the sector flanges C. In case one or more sectors anges of the sectors, as shown should become damaged it is obvious that the damaged sector can be quickly and easily removed by withdrawing the rive-ts or bolts and forcing the sector axially outward and the new sector can then be substituted for the removed sector and secured in place by rivets or bolts as previously described.

Having thus described my invention, what I claim is:

l. A disk wheel composed of a plurality of sheet metal sectors, each sector having axially extending radial flanges and an axially extending a-rcuate flange.

2. A disk wheel composed of a plurality of sheet metal sectors, each sector compris ing an arcuate flange and radial flanges,

all of said flanges being arranged axially and a hub to which said radial flanges are connected.

A disk wheel composed of a plurality of sheet metal sectors having radial flanges and a hub having bosses, said bosses being divided, the contiguous radial flanges of the sheet metal sectors being secured in said radial bosses of the hub.

4. A disk wheel composed of a plurality of sheet metal sectors having radial flanges, said radial flanges being upset adjacent their inner ends, and a. hub having radial bosses, said bosses being divided and bored, the contiguous flanges of adjacent sectors being in the divided and bored bosses of the 5. In a Wheel the combination with a hub having axially bored and slotted bosses,

of a disk having axially disposed portions adapted to engage said bored-and slot-ted bosses and means for securing said disk portions to said bosses.

6. In a wheel the combination with a hub of a plurality of sheet metal box-like sectors connected together and constituting a-disk, said disk being demoimtably con nected to said hub.

7. In a wheel the combination wit-h a hub having axially extending bosses of a plurality of sheet metal sectors connected together and detachably connected to said bosses.

8. A disk wheel composed of a plurality of sheet metal box-like sectors having their radial flanges abutting one another, the arcuate flanges forming a support for the rim.

' In testimony whereof I hereunto afiix my signature.
