METAL WHEEL.

Application filed June 19, 1925. Serial No. eases.

This invention relates to an improved spoked metal wheel. The spoked type of metal wheel is not broadly new. One of the common designs of the prior art is a wheel made of two" stamped sections. lock-seamed or otherwise secured together along the spokes. This design. while resulting in a satisfactory wheel, is relatively expensive, as it involves great waste in punching out the wheel sections.

, It is the obiect of the present invention to provide a wheelwhich is capable of being produced by die operations. with a minimum amount of waste, and which affords double reinforcing webs at the center of the wheel at which the entire load is concentrated.

Referring to the drawings:

Fig. 1 is a side elevation of one form of the completed wheel.

Fig.2 is a cross section of the same.

Fig. 3 is a plan view of one of the sections,

before it has been punched out at the center.

Fig. 4 isa plan view of the other section.

FFig. 5 is a section on the line 5-5 of lz iFig. 6 is a section on the line 6-43 of Fig. 7 is a section on the line 77 of Fi Fl ig. 8 is a section on the line 8-8 of Fig. 9 is an elevation looking at the end of the spoke.

Fig. 10 is a cross section through the fixed rim and demountable rim.

Fig. 11 is a cross section on the line 1111 of Fig. 1.

Fig. 12 is a cross section on the line 1212 of Fig. -1.

Fig. 13 shows the wheel applied to a drop center rim.

The improved wheel is a plural-section, stamped metal wheel, in which there is more than one wheel section on each side of the wheel; the wheel sections each extending clear across the wheel from one side of the circumference to the other side. giving the multiple ply web at the center of the wheel.

ings.on each side of the wheel is a section a. which is slightly offset at the center a to receive the other section b. in lapping relation. These sections can be fitted together to complete the 360 degrees. or one side of the wheel. sections have flanges c on the spoke sections arranged to co-operate with similar flanges (Z. shown in dotted lines in Figs. 7 and 8 to" form a locleseam along the spoke to lock the inside and outside portions of the wheel together. They may be also welded together or joined in any other suitable manner. it being understood. of course, that the sections can be locked together by suitable welding operations in place of the lock-seam arrangement. this being a mere detail of construction.

From a comparison of Fig. 9 and Fig. 1, it will be seen that the end of the spokes are flared out as at f, and then provided with a turned-over flange h, which in turn is provided with a second turned-up flange 5. These two flanges fit one on the inside of the fixed rim and the other on the side of the fixed rim. This, however, simply illustrates one way of fastening the ends of the spokes to a fixed rim. In so far as the broad sectional construction of the wheel is concerned, I do not desire to be limited by any form of fastening the spokes to the fixed rim.

Referring now to the center construction of the wheel, it will be seen that by lapping the wheel section at the center this provides a multiple ply center web 1'. This is desirable as it gives the wheel double strength at the center where the load is concentrated. The sections are referably punched to receive the bolts which secure the hub flange m to the outer cap flange n. This secures the hub o in place at the center of the wheel. However, thisconstruction may be In one form of the wheel. the

varied within wide limits. It simply illustrates one way of affording a suitable hub. The wheel shown in Fig. 2 also has the brake drum 7) bolted in place by the same The fixed rim q is a channel rim provided with the usual inner inclined flange 1'. The (lQIHOUIItablQI'lIlI 8 can be provided with the well known Hayes"type of fixed lug t, and obviously by turning down the nut u on the end of the bolts w the demountable rim can be clamped to the fixed rim. This again simply illustrates a suitable fixed rim and demountable rim construction, and we desire in no way to be limited to this.

A great advantage of the wheel construction which is here described is that the same can be made by simple die operations, .and with less waste of material. For instance, the blanks can be just the size of the wheel sections shown in Figs. 3 and 4. This will involve simply the waste of material between the spokes. But: still more advantageously, this sectional "construction of the wheel permits these wheel sections to be stamped from blanks without any waste of mate-rial between the spoke sections. This is fully described and claimed in our copending application Serial No. 38,204, where there is described in detail a method by which one of these wheel sections may be made from a blank of smaller dimensions than that of the wheel section. This is done by folding and drawing the blank at the ends, splitting the ends and then spreading the split portions apart to produce each a spoke section. The exact method is here only indicated in a general way, for as already stated, each wheel section may be made by this method or may be produced from a blank of the same size as the wheel section with, however, a greater waste of material.

Preferably a filler block at is used at the center of the wheel to increase its strength.

What we claim is:

1. A wheel, having in combination a plurality of sections on both the inside and out side of the wheel arranged to each form a center with diametrically opposed half tubular spoke portions, the said sections being secured together.

2. A wheel, having in combination a plurality of stamped metal sections, there being a plurality of sections on the inside and also 11 the outside of the wheel and each section having a half tubular spoke portion and an annular center portion, the sections being secured together with the annular center portions overlapping and the half tubular portions matching together.

3. A wheel, having in combination a pluralityof stamped metal wheel sections, there being a plurality of sections on both the inside and outside of the wheel, each section having hollow spoke halves and extending between diametrically opposite points on the periphery, said sections being secured together to form a tubular spoked wheel body.

4. A wheel, having in combination a plurality of stamped metal sections, there being aplurality of sections on both the inside and outside of the wheel and the sections having hollow spoke parts and extending between diametrically opposite points on the periphery and being overlapped at the center to form multiple ply center webs, the said sections being fastened together to form a hollow spoked wheel body.

5. A wheel, having in combination a plurality of wheel sections of metal, there being a plurality of sections on both the inside and outside of the wheel and each section formed into tubular Spoke halves and extending between diametrically opposite points on the periphery, the said sections being secured together to form a spoked wheel and wheel center.

6. A wheel, having in combination a plurality of metal wheel sections formed into a plurality of spoke sections at each end of each section, each section extending between diametrically opposite points on the periphcry. and the sections on one side of the wheel lapping at the center to form a multiple web wheel center, and the spoke sections secured together to form complete spokes.

7. A wheel, comprising a pair of fashioned metal wheel sections on each side of the wheel making four sections in all. each wheel section formed at each end with a pair of spoke sections and each section extending between diametrically opposite points on the periphery with the sections lapping each other at the center and the spoked sections matched together to form a complete spoked metal wheel body with a reinforced center.

8. A sheet metal wheel, comprising a wheel body made up of four stamped sheet metal wheel sections, each wheel section comprising four spoke halves, said sections being fitted and secured together with the spoke halves matched together to form a complete wheel body.

9. A sheet metal wheel, comprising a wheel body made up of four stamped sheet metal wheel sections, each wheel section comprising four spoke halves, said sections being fitted and secured together to form a complete wheel body with lapped webs at the center and spoked halves matched together,

forming a. reinforced wheel body adjacent the hub. r
