This is for the reason that the threads of the outer clamping member are of greater radius than those for the inner clamping mem ber and, consequently, the eifective frictional resistance to the turning of the outer member on~ the inner member is greater than the resistance Figs. ‘land-2 in whichG is a disc member detach ably and non-rotatably. engageable with the clamping member E. As speci?cally shown in Figil2githe member E has a polygonal portionE? tween the wheels C and D and the ‘discG- is provided witha correspondingly shaped‘ aperture. therein.» Thus, after the inner wheel C has, been clamped-by the screwing of the members, upon - the studs B, the member G is engaged with the polygonal portion E2. As usually constructed, the hub A has a projecting ?ange portion A’ on which the wheels 0 and D are piloted when engaged with the ‘studs B. To avoid interference with the ?ange A’ during engagement of the disc G with to turning of the inner member on its threaded 30 the portion E2, the outer periphery of'the disc has a small radius portion G’ which clears the bearing. As a result, the unscrewing of the outer ?ange A’ and also a large radius portion G2 which member carries the inner member with it so that lies adjacent to said ?ange. Thus, any rotation both wheels are simultaneously unclamped. of the member E on the stud B will be prevented It is the object of the invention to provide means for preventing the loosening of the clamp 35 by the member G. This member does not inter fere with the mounting of the wheel D or the ing means for the inner wheel during the un clamping by the nut F. However, if the nut F screwing of the clamping means for the outer is unscrewed to release the wheel D, this; cannot wheel. To this end the invention consists in rotate the member E on the stud B. On the other the construction as hereinafter set forth. ' hand, if after removing the wheel D the wheel C In the drawing: 40 is also to be released, then the member G may Fig. 1 is a sectional elevation showing a portion be easily disengaged from the portion E2 of the of the hub and one of the studs of a dual wheel member E after which the latter member may be mounting to which my improvement is applied; turned to unscrew it from the stud D. , Fig. 2 is a section on line 2-2, Fig. 1; As above described, the dual wheel mounting Fig. 3 is aview similar to Fig. 1 showing a slight 45 without the polygonal portion E2 on the clamping ly modi?ed construction; ~ member E has heretofore been manufactured and Fig. 4 is a, similar view of another modi?cation; used. In order to provide such construction with Fig. 5 is a view similar to Fig. 2 of another modi my improvement, I have devised the construction ?cation. As shown in Fig. 1, A is a portion of a vehicle 50 illustrated in Fig. 3. In this a member E3 is simi lar to the member E but without the polygonal wheel hub and B is one of the threaded studs pro portion E2. H is a nut engageable with the ex- , jecting outward therefrom. C‘ is the inner wheel and D the outer wheel, both being apertured to ' receive the stud B. The inner wheel 0 is clamped by a member E which is internally threaded to terior threads E4 and which is screwed thereon against the shoulder E5 of the portion forming the conical bearing E’. The exterior of the mem 55 ber H is either polygonal orotherwise fashioned ‘ . . member for securing the outer wheel to said hub; to form a non-rotative engagement with the disc G and the construction is otherwise the same as of means for locking said ?rst mentioned clamp ing member against rotation comprising a mem-_ above described. ber axially and non-rotatably engageable there - . With the modi?cation shown in Fig. ,4, inplace with in a plane between said wheel members and having an eccentric portion bearing against a por of using a nut E engaging the stud B for clamping the inner wheel, a tap screw I engages a threaded socket A2 in the hub and is provided with a coni-‘ tion of said hub.- ' 3.
