WHEEL.

Application filed December 1, 1924.

Wheels, of which the following is a full,

clear, and exact description.

My invention relates to improvements in wheels, and it consists in the combinations, constructions, and arrangements herein de scribed and claimed.

An object of my invention is to provide an improvement over that form of the device shown in my co-pending application for wheel, Serial No. 232,835, filed August 18,

1924:. In said" co-pending application I showed a device in which the rim could be positively moved into locking engagement with the felly of the wheel, and positively loosened from the felly, these two operations being accomplished by a single bolt. I further showed novel means for wedging the rim to the felly at various places, whereby the felly could be readily secured to the rim.

' ihe principal object of the present application is to construct the means for securing the rim to the felly in such a manner that the rim, although rigidly secured to the device, will not be so fastened to the felly that it cannot be readily released from the felly.

A further object of my invention is to provide a wheel in which the felly has novel means for engaging with both sides of the rim so as to provide a large supporting surface for the rim. 7

A further object of my inventionis to pro vide a wheel which is extremely simple in construction, positive in operation, andwhich is durable and etlicient for the purpose intended. V

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a plan view of a portion of the felly,

Figure 2 is aside elevation or Figure 1,

Serial No. 753,282.

Figure 3 is a section substantially alongthe line 33 of Figure 2,

Figure 4 is a plan View of another portion of the felly,

Figure 5 is a side elevation of Figure 4, Figure 6 is a section along the line 66 of Figure 5, and

Figure 7 is a section through a modified form of the device.

In carrying out my invention I provide a felly which in the present instance is con structed of metal and which is provided.

with a cylindrical portion 1, (see Figure 6) and outwardly extending flanges 2 and 3. The felly is mounted upon spokes 1 and is provided with openings 5 in which the free ends of the spokes 4 are received. It will be noted, from Figures 1 and 6 that the flanges 2 and 3 are bent inwardly at 6 and 7 so as to provide inclined surfaces for a purpose hereinafter described. It willalso be noted that the sides 2 and 3 and the inclined surfaces 6 and 7 act as reenforcing means for the felly.

The means for locking the rim 8 to the felly consists in a locking plate 9 and looking projections 10. I have found that three or four projections 10 spaced equally. about the rim are sufficient for locking the rim to the felly.

Figures 1 to 3 inclusive clearly show the locking plate 9 while Figures 4 to 6 in elusive show one of the locking projections 10..

I will now define the specific construction of the rim locking plate 9. In Figure 2 it will be noted that the felly 1 is provided with a depression 11 which is adapted to receive a bolt 12. The bolt 12 is provided with a non-circularhead13 and a non-circular nut 14. The bolt and nut have coniv cal- shaped portions 15 and 16. The sides 17 and 18 have conical- shaped openings 19 and 20 therein in which the conical portions 15 and 16 are rotatably disposed. This constructioii permits the bolt 12to be rotated,

through which the bolt 12 extends. It will therefore be seen that when the bolt 12 is rotated, it will move the locking plate 9 with respect to the telly 1. In Figures 1 and 3 I have shown the side 3 as being provided with an opening 23 through which the locking plate 9 is adapted to slide. The side 2, however, is cut away as at 24, (see Figure 1) so as to permit the movement ot the locking plate 9 with respect to the telly In the present torm ot the device the locking plate 9 is rectangular in shape and has two outwardly extending ribs 25 which are inclined with. respect to the axis of the bolt 12, (see Figure 1). The ribs 25 provide a channel 26 in which a projection 28 carried by the rim 8, is adapted to be received.

The projection 28 is punched out ot the inner side otthe rim 8 and'is provided with tapered sides 29, which permit the "projection to be readily received in the channel The cam sides 29 are shaped so as to permit the rim to be formed by dies. The projection 28 is turned so as to have its side 30 disposed parallel with the inner wall of: one of the ribs 25. It will also be noted that the projection 28 does not contact with both ot the inner walls ot the ribs 25. This permits a movement of the locking plate with respect to the projection 28 tor a purpose hereinatter described.

It will be noted that when the locking plate 9 is moved, it will move the projection 28 laterally so as to move the rim 8 into locking position. This movement is positive, since the ribs engage with the projection 28 and move the projection. It will be noted that the locking plate 9 has the channel 26 thereof provided with an inclined portion 31. The inner side ot the projection 28 is moved into contact with the inclined portion 31 by a means hereinafter described, and when the projection 28 so engages with the inclined portion it will be moved away from the telly 1 so asto cause the rim to bind to the telly. IThc projection 28 rotates the rim slightly with respect to the telly 1 but does not prevent lateral movement of the rim with respect to the telly.

The n'ieans tor preventing lateral movement ot the rim with respect to the telly consistsot the PlOjCCilOHS 10 and camshaped portions 6 and 7 ot the telly. Fig ure 4' showst-he projection 10 as being provided with an inclined surtacc 32. Figure 6 shows how-the beveled side 32 contacts with the inclined portion6 and Fig. 4 shows the portion 6 cont as being inclined at The side 32 ot the projection 10 and the portion ot the inclined surtace (i coact with each other so as to cause the pr jection 10 to be moved inwardly in the direction indicated by the arrow a and also radially from the telly 1.

acted by the projection 10 so as to cause the rim to bind with the telly. As heretofore stated, the projections are dis posed about the rim and therefore bind the rim to the telly at various points about the telly so as to make a rigid connection be tween the rim and telly. In addition to the contacting ot the surtaces 32 and 33 the rim 8 also bears against the inclined surface 7. It should be noted that the surtace 7 contacts with the rim 8 throughout its entire circumference, thus providing a large sup porting area tor the rim. The movement ot the projection 10 in the direction of the arrow (4 causes the portion 3a of the rim 8 to contact with the inclined surface 7 The inclined surtace causes the rim to be moved slightly away trom the tellyso as to bind the rim to the telly and prevent movement thereof with respect to the telly.

The valve of. the tire (not shown) is first inserted in the opening therefor in the folly and then the rim is swung so as to dispose the rim on the telly. The projection 28 is disposed diametrically opposite trom the valve so as to permit the rim to be readily applied to the telly; The projection 28 and the project-ions 10 are aligned with the channel 26 and the recesses 37 respectively when the valve is inserted in the opening therefor in the telly. This permits the opera tor to swing the rim into place. The opera tor then rotates the bolt 12 by means of a wrench, whereupon the locking plate 9 will move the projection 28 circumferential]y to cause the projectionslO to engage with the surface 6 and thus wedge the rim to the telly. The rim and telly have been designed so as to consist of a number 0t inclined surfaces which engage with each other so as to wedge the rim to the telly when the plate 9 is moved.

W hen releasing the rim the bolt 12 is rotated in the opposite direction and causes the projection 28 to move the rim so as to align the projections 10 with the recesses 37. As heretofore stated, the sides ot the projection 28 do not contact with both sides of the channel 26. There is therefore no tendency tor the projection to become locked in the channel. In case the side 30 should adhere to the wall of the rib 25, a slight tap upon the rim with a hammer or other tool will release the projection and permit the plate to move the projection. In this way the rim may be readily released from the telly even though the rim has been rigidly secured to the telly tor a long time.

The weight ot the rim with the tire on it is so great as to render the mounting of: the rim on the telly quite ditlicnlt it it were necessary to push the rim onto the telly and at the same time turn it to cause the usual wedging action which forces the rim into position, as set forth in my above menvt-ioned application, But this weight becomes of great assistance in the present case for the recesses formedby cutting away the flange 6 of the felly in order to admit the projections 10 permit the free entrance of these projections.

lVhen the rim is lifted onto the wheel, and the tire tube valve stem is inserted in the properhole therefor in the felly in the usual manner, the rim and tire thereon may be swung away from the felly and then violently swung back against the felly. The projections 10 enter their recesses-withoutmeeting any obstructions but the projection 28 contacts with the inclined shoulder :25 (on the right side of the lock plate in Fig. 1). As this look plate can be properly positioned by means of the bolt 12, this en gagement takes place just before the rim engages therear flange on the felly at 7.

This forcible engagement of the projection 28 with the inclined shoulder forces the rim to slide around circumferentially on the felly to such an extent that the projections 10 will extend back of the inclined shoulders 33 (Figs. 4- and 5). sutliciently to hold the rim in position on the felly. It is then merely necessary to turn the bolt 12 to pull the lock plate outward, which results in all the projections 10 riding up on the inclined surfaces 33 and the rim being locked in position.

This initial kick causing the partial rotation of the tire following the slam of the rim against the felly is of great importance for the changing of this rim is thereby rendered as simple and easy as that of the present demountable rim, If the rim were given no initial rotation to bring the pro jections 10 into operative position to hold the rim on the felly, the inclined shoulder on the locking plate, when pulled out against the projections 28, would merely push the rim off the felly. But when such movement is preventedby this operative engagement of the projections 10, the rim is forced to slide around the felly. As only a single locking bolt is necessary in the present construction, the time required to change rims is materially reduced and the cost of construction correspondingly diminished.

The depression 11 permits the felly to use a rim which is of special construction. The rim is shown in Figure 3 as being provided with a supporting surface 38 for the outer casing, and a supporting surface 39 for the inner tube. In this type of rim, when the tire is deflated, the outer casing may be forced down into contact with the surfaces 39 and thereby permit the outer casing to bulge at one point so as to free the outer casing from the rim at this point, and allow it to be removed from the rim. It is obvious that the felly may support the standard rim with but slight alterations. The arrangement of the contacting surfaces in the rim and felly is such as to provide a device in which the rim willbind with the fellyxeven though there is a slight imperfection insthe parts, and even after the rim and felly have become slightly worn through use. 4) are inrealit-y double cam surfaces, which not only movethe rim laterally with respect to the folly l but also radially.

In Figure 7 I have shown amodified form of the device which is identical with the preferred form except that it is adapted to be used with disc wheels. In this Figure I have shown a disc wheel 40 which has a locking plate actuating bolt 41 rotatably carried by the disc 40. The locking plate 42 operates in the same manner as the plate 9 and locks the rim 8 tothe disc wheel in the same manner as is done in the preferred form of the device. The disc wheel i0 is fashioned into a cylindrical portion l?) which is similar, to the cylindrical portion 1 (see Figure 6) and is also provided with a cam-shaped surface l4: which is similar to the surface 7 (see Figure 6). The operation of this form of the device is identical to the preferred form and therefore needs no further description.
