METHOD OF MAKING SHEET-METAL WHEELS.
Application filed April 12, 1923. Serial No. 631,734.
This invention relates to new and useful improvements in sheet metal wheels, and has particular reference to pressed or rolled steel wheels having the hub, rim and intermediate parts integral.
It is the principal object of my invention to provide a strong, durable and compact wheel which may be economically made from a single blank of steel or other suitable metal by different pressing or rolling opgrations.
The invention essentially consistsin constructing the wheel from a blank of sheet metal, preferably steel, by different operations, with a view to reducing the cost of manufacture of the wheel as well as lightenin and strengthening its structure.
Tn the accompanying drawings, Figure 1 is a longitudinal, sectional view through a metal blank, showing the hub partly drawn in a preliminary forming operation. Figure 2 is a longitudinal, sectional view taken through the blank on the line 2-2 of Figure 11 after the spokes and rim are half formed. Figure 3 is a cross sectional view taken on the line 3-3 of Figure 2, showing a spoke half formed. Figure 4 is a longitudinal, sectional View taken through the wheel, showing the hub, spokes and rim fully formed. Figure 5 is a cross sectional view taken on the line 55 of Figure 4, showing a closed-in spoke. Figure 6 is a longitudinal, sectional view taken through the wheel, showing a hub bushing inserted therein. Figure 7 is a cross sectional view taken on the blank of metal,
line 77 of Figure 6, showing one means of connecting the free ends of a formed spoke. Figure 8 is a longitudinal, sectional view taken through a wheel having a hub, rim and an intermediate disc ortion-formed from a single blank of metal. Figure 9 is a 1ongitudlnal, sectional view taken through the same after the top of its hub portion has been turned down against the intermediate disc portion of the wheel. Figure 10 is a partial side view of a wheel formed as illustrated in Figures 8 and 9. Figure 11 is a partial side view of the spoke wheel partly formed. And Figure 12 is a full side view of the finished spoke wheel.
Throughout the specification and drawings, similar reference characters denote corresponding parts.
Referring to Figure 1 of the accompanying drawings, the numeral 1 designates a preferably steel, which'has been subjected to a preliminar stamping, or a rolling operation, to part y draw the hub portion 2 of the wheel, although any other part of the latter may be first formed if desired. Figure 2 shows how the hub portion 2 and the spokes 3 are half formed after a second operation has been performed upon the blank. The next forming operation to which the blank is subjected, closes in and forms the spokes 3 and the rim 4, each spoke becoming a split ring in cross section as shown in Figure 5.
In order that sutficient metal may be available to fully form the spokes 3 and the rim 4 at the seams 5 shown in dotted lines in Figure 12, the rim isformed with corrugations 6 for expansion, under the force of the bending operation to which the blank is subjected, to yield suflicient metal to fully close in the spoke and rim portions at. the scams 5. See Figures 2, 11 and 12.)
After the wheel structure has been formed as just described, a bottom flanged T member 7 is inserted between the free ends of the spoke portions 3 and welded thereto for the purpose of forming a tight connection between said ends as shown in Figure 7. However, any other suitable form of connecting means may be employed if desired.
A hub member 8 having an annular flange 9 formed around its lower exterior portion to receive the lower end of the hub portion 2 of the blank 1, is inserted in said hollow hub portion. The member 8 has an upper web portion 10 which is suitably connected to the upper portions of the inner ends of the spokes 3, thereby completing the wheel structure.
My metal wheel may also be stamped or rolled from a single blank of metal, to the shape shown in Figure 8. In this instance the entire hub 11, which is integral with the intermediate portion 12 of the wheel, projects a 'suflicient distance beyond said intermediate portion to be turned inwardly against it as shown in Figure 9. The intermediate portion 12 is made in disc form, as shown in Figure 10. The rim portion 13 is formed integral with the intermediate disc portion 12 of the wheel, and since the hub 11 of the latter is also integral with the intermediate portion, the entire wheel becomes one which is entirely made of a single blank of meta I do not wish to be limited to the details of and described, and any changes or modifications may be made therein within the scope of the sub oined claims.
Having described m invention, I claim:
1. The herein descri ed process of making a vehicle wheel from a sheet of metal, which consists in forming ahub part, a rim part and intermediate integral spoke portions, the rim part being formed with corrugations be-. tweenthe spoke portions for expansion to provide suflicient metal to completely form the spoke portions and the rim at their meeting points.
2. The herein described process of making a. vehicle wheel from a single sheet metal, which consists first in bending the metal sheet to partly draw the hub part, then half formmg the hub and the spoke portions and then closing in the blank to form the spokes in the shape of a split rin in cross section.
3. The herein descri ed process of making a vehicle wheel from a single sheet metal, which consists first in bending the metal sheet to partly draw the hub part, then half forming the hub and. the spoke portions, then closing in the blank to form the spokesvin the shape of a split ring in cross section, then inserting a member between the free edges of the spoke portions and then welding it to them.
In testimony whereof I have hereunto set my hand this 11th day of April, 1923.
