2 Claims.

This invention relates to new and useful improvements in metal Wheels.

It is the principal object or" my invention to provide a metal wheel in which a positive alinement o the rim or rims with the felloe is sirnply and easily effected.

In the dual wheel the inner rim is turned by wedge action to its home position, where it remains independently oi the outer rim. The latter is then turned to its home position by wedge action, both rims being held by the wedge means in positive alinement with the felloe at all times and under all conditions of use.

In the single wheel the rim is turned by wedge or cam action to its home position in the same manner and by the same means employed for effecting this result with the inner rim or the dual wheel.

Other important and incidental obiects will be brought out in the following specification and particularly set forth in the subjoined claims.

in the accompanying drawings, Figure 1 is a side elevational view or" my improved wheel. Figure 2 is a sectional view taken through the same on the line 2 2 of Figure l. Figure 3 is a sectional View taken through the wheel on the line 3 3 of Figure 1. Figure ll is a side view oi the same at one of the lugs. Figure 5 is a face view of the tire riin at one of the lugs. Figure 6 is a face view of the ring at one of the lugs. Figure 7 is a face view oi the ielloe at one of the lugs.

Figure 11 is a face view of the modied form of ring and ielloe construction. Figure 12 a side elevational view of a spider wheel ernbodying my invention. Figure 13 is a radial sec- -0 vtional view taken through said wheel. Figure 14 is a cross section `take on the line 14-14 of Figure 13. Figure 15 is a cross section taken on t -e line 15-15 of Figure 13. Figure 16 is a sectional view taken through the inboard side of a n spoke end, showing one of the wedge bolts. Figure 17 is a sectional view taken on the line 17-17 of Figure 13. And Figure 13 is a top view of a wedge and wedge bolt for the outboard tire rim.

Referring to the accompanying drawings for a detailed description of my invention, the numeral 1 designates the hub, 2 the spokes and 3 the ielloe of a dual wheel. This felloe, which may be also that of a dise wheel, is formed with two separated beveled seats, the inboard seat 4 and the outboard seat 5. (See Figure 2.)

The inboard seat 4 is adapted to positively support a tire rim 6 which is formed with a beveled part 7 from which there projects radially inwardly a series of lugs 8 which it in inclined grooves 9 in the felice. (See Figures 2, 3 and 7.)

1928, Serial No. 309,706

(Cl. 30ll7) For the purpose of engaging the lugs 3 to force them into the grooves 9 in the ielloe to screw the inboard rim 6 to its home position, l'. provide the following means. Referring to Figures 2 and 3, there is formed on the inboard portion of every other spoke, a boss 10 which has a radially outward tapered flange 11. Free to slide axially inward along this nange is an l. shaped cam member i2. The axially inward projecting part 13 oi the cani member l2 is inclined and is free to slide into a recess in the ielloe. (See Figure 3.) The radially outer periphery or" this projecting part ci the cani member 12 is tapered or beveled to engage a respective lug 8 on the rim.

Formed in the axially outer part of each cam member 12 is a hole through which a screw 14 is inserted for entrance into a threaded hole in the felloe to draw the cam member axially inward. During the axially inward movement of the cam member, its beveled surface will engage a lug 8 to slide it further in its inclined groove 9 in the felloe to screw the tire rim on the latter .until it reaches its home position, where it will be positively alined with a plane at right angles to the axis of the wheel.

The screw 14 is arranged to be inserted in the inclined manner shown Figures 2 and 3 so that it will be accessible for easy operation fromV the outside by a screw driver.

The means for bringing the outboard rim to its home position reduire additional elements such as the Wedge ring and associated parts now to be described. Such additional means are necessary to provide a clearance for the inboard rim which is first applied to the felloe.

Referring tc Figures 3, 4, 5 and 7, there are provided 'io-r entrance into square recessed portions 16 oi the outboard part 17 oi the ielloe, cam members 15. These cam members are similar to the cam members 11 save that their beveled projections 13 are at right angles to the recessed iront portions which receive the heads of screws 19.

The numeral 21 designates an outboard tire rim formed with a beveled portion 22. Formed on this beveled portion 22 are lugs 23 that enter slots formed in a split wedge ring 24. Screws 25, whose heads rest in recessed portions oi the ring, pass through holes in the latter Yto engage the lugs 23 for the purpose or" rmly securing the ring to the tire rim 2i. This wedge ring 2li occupies between the cam members 15 and tire rim 21, the space which it is necessary to leave for the insertion of the inboard tire rim;V

Formed in the periphery of the felloe portion 17 are inclined grooves 26 to receive lugs 27 on the ring 24, similar to the lugs 8. (See Figures 3, 4, 6 and 7.) When the cam members l5 are moved into recesses in the felloe by the screws 19, their beveled surfaces will engage the lugs 27 to slide them longitudinally in the grooves 26. And as they move further into these grooves in the felloe, the ring 24 and the outboard tire rim 21 to which it is attached, will be screwed onto the felloe until the rim reaches its home position, where it will be in a plane at right angles to the axis of the wheel.

After the inboard tire rim 6 is secured to the felloe, the wedge ring 24 is applied to the outboard rim 21, with the lugs 27 within the grooves 26 in the felloe, after which the cam members 15 are inserted to screw the last named rim to its home position.

A modied form of construction of split wedge ring and associated parts for use with the cam members 15 in screwing on the outboard rim 21, is shown in Figures 8, 9, 10 and 11. The numeral 28 designates the wedge ring for engagement with the beveled part 22 of the rim 21. (See Figure 8.)

Lugs 29 are formed on the tire rim 21 for entrance into slots formed in the ring 28. U shaped clamps 30 which t in grooves in the ring 28, are provided for assisting the lugs 29 in holding the ring rmly on the tire rim. As shown in Figure 8, these clamps engage the ring and the tire rim, with screws 31 passing through holes in the clamps for engagement with the sides of the rim. When these screws'are tightened, they will rigidly anchor these clamps to the rim to assist the lugs 29 in solidly` securing the ring 28 to it.

When the cam members 15 are moved axially inward by the screws 19, they will engage the lugs 27 and force them into the inclined grooves 26 in the periphery of the felloe portion 17, with the result that through the agency of the ring 28, the tire rim 2l will be screwed to its home position on the felloe.

In the case of a single wheel, the cam members 12 and associated parts may be employed for screwing a tire rim constructed like the tire rim 6 to a position on the felloe where it will be in a plane at right angles to the axis of the wheel.

lVIy invention may be applied with equal facility to a spider type of metal wheel. Referring to Figures 12 and 13, the numeral 32 designates the hub portion and 33 the radial hub extensions or spokes of a spider 34. The extensions or ribs 33, which are U shaped at their radially inner portions as shown in Figure 14, are joined to a brake drum 35. Beyond the periphery cf this drum, each spoke end 33 is formed in the manner shown in Figure 15, the outboard side curv ing axially outward to form a beveled seat 36 for an outboard tire rim 37, while the inboard side of the spoke end projects radially outward in a straight line to form a beveled seat 38 for an inboard tire rim 39. (See Figure 13).

For the purpose of screwing the inboard tire rim 39 to its home position on the beveled seats 38 on the spoke ends, the following construction may be employed. Referring to Figures 13, 16 and 17, there is formed on the axially inner part of the seat portion 38 of each spoke end, a boss 40 having an axially outward inclined face 41. Adapted to slide along this face to draw the inboard tire rim 39 inwardly, is an inclined rib 42 on said rim. This rib or projection is adapted to be engaged by the tapered surface 43 of a wedge or hook bolt 44 in a hole in the spoke end.

Applied to the threaded end of each bolt 44 is a nut 45 which, when tightened, will draw the tapered surface 43 on the bolt head against the rib 42, the bolt head being restrained from turning by a lug 44a on the spoke end. The ribs 42, when so engaged by the bolts 44, will slide along the inclined faces 41 of the bosses 40 on the spoke ends, which bosses act as flanges to force the beveled part of the inboard tire rim tightly upon the beveled seats 38 on said spoke ends. Thus, as the tire rim 39 is turned circumferentially by the wedge bolts 44, it will at the same time be moved laterally to its home position on the spoke end seats 38.

In order to provide a clearance for the inboard tire rim 39 when it is applied to its seats 38 on the spoke ends, I provide removable wedges for use with the hook bolts in screwing the outboard tire rim 37 toits home position on the spoke end seats 36. Referring to Figures 13 and 18, there is provided for support upon each beveled spoke end seat 36, a wedge piece 46 which is tapered on its outboard part to act as a removable seat for the beveled portieri of the outboard tire rim 37. Each wedge piece 46 is formed with a beveled lug portion 47 which is adapted to be 100 engaged by the tapered surface 43 of a wedge bolt 44. rEhe heads of the bolts 44, and the lugs 47 which they engage are located in recesses in the spoke ends, with the threaded ends of the bolts' projecting through holes in said spoke ends 105 to receive nuts 48.

Formed on the spoke ends for engagement by the lug portions 47 on the Wedge pieces 46, are bosses 49 with inclined faces 50. (See Figure 18). Therefore, when the nuts 48 are tightened, 110 the tapered heads of the wedge bolts 44 will engage the wedge pieces 46 and move them along the tapered bosses 49 on the spoke ends. These bosses then act as flanges to torce the wedge pieces 45 axially inward as they are moved cir- 115 cumferentially by the wedge bolts. And as the wedge pieces 46 are moved axially inward, they will effect a positive seating of the outboard tire rim 37 on its spoke end seats 36, for the tapered faces of the wedge pieces engage the beveled part of the tire rim. Ribs 51 on the latter act as flanges for the inboard sides of the wedge pieces.
