To all whomc't may concern:
Be it known that we, LEROY BAUMeAn'iL and HENRY F. GASTON, citizens of the United States, residing at Chicago, in, the county of Cook and State of Illinois, have invented a new and useful I-m rovement in Demountable Wheels, of w ich the following is a "specification.
ably holding the outer hub-member in such relation to the inner hub-member that these two members will operate as a. unit.
@ur primary ob ects are to provide improvements in wheels of the character above referred to,'to the end that the operation of assembling the outer hub-member and the partscarried thereby, with the inner huhmember, and the disassembling of these parts, may be effected easily and quickly, the outer hub-member being positively held to the innerhub-member when in assembled relation, regardless of slight variations in the proportions of the parts, whether resulting in the manufacture of the wheel or by wear of parts, and under the stresses to which the wheel'is subjected in actual and continued use; and to the end that the outer hubmember shall be held against baclclashing.
Referring to the accompanying drawings:
Figure 1 is a view in longitudinal sectional elevation of a wheel structure constructed in accordance with our invention, the section being taken at the line 1 on Figs. 2 and 4 and viewed in the direction of the arrows.
. Fig. 2 is a sectional view taken at the line 2 on Fig. 1 and viewed in the direction of the arrow, certain of the parts being shown in elevation.
Fig. 3 is a section taken at the line 3. on Fig. 1 and viewed in the direction of the arrow.
Fig. i is a section taken at the line 4 on Fig. 1 and viewed in the direction of the arrow.
Fig. 5 is a view 'in elevation of one of the plurality of plunger devices employed; and
Fig. 6, a si-milad view of the lunger dcvice shown in Fig. 5, this view sing taken from the left hand side of Fig. 5.
We have chosen to illustrate our invention as applied to a wheel structure journaled on an axle as in the case of the front wheel of an automobile though it will he 1 readily understood from the following that the invention is not limited to a wheel of this character, but is equally applicable to a drive-wheel. I A
One of the front steering axles of an au tomob'ile is represented at 7, this axle carrying ball-races 8 and'ii, between which are imposed the races 10 and 11 carried by the inner hub-member 12, balls 13 and 14: being interposed between the opposed races 8' and 10 and 9 and 11 and forming a. ball bearing upon which the hub-member 12 is supported on the axle 7 to rotate thereon, the hubmember 12 being hollow and preferably having its outer end tapered, as indicated at 15. The outer hub-member of the wheel is represented at 16, this hub being connected with the rim, or felly, (not shown) through the medium of the spokes 17. The outer hub-member 16, spokes 17, and felly would thus be connected together. and the whole is adapted to he bodily removed from and assembled with, the inner hub-member 12, as desired, the outer hub-member 16 likewise being hollow and of such internal form that it will snugly fit over the inner hub-merit her 12.
The inner hub-member 12, is open at its outer end, (the righthund end in Fig. 1) and the metal forming this end of the hub is slit-ted longitudinally thereof, as at the three places indicated at 1 8 in Fig. 3, for a purpose hereinafter described, the angle at which the outer tapered surface of'this part of the member '12 extends relative to the median line of the hub being slightly less than the angle of the main tapered portion of the hub. The hub-member 12 contains in its periphery, a plurality. of radially-disposed epenings, or eockets, 19, shown as three in num er, though. the number thereof may be varied as desired, these openings, or sockets, by preference. being offrusto-conical form with their walls flaring radially outward, and according to the particular cbnstru'ction illustrated being formed partly in inset bosses QO-arranged about the inner circumferential surface of the member 12,
'forcooperat on with devices carried by the outerQhuh-member 16 and adapted'to be prointo these sockets for releasably lock- QQ ,ing' theIouter-hub-member to the'inner hub- 1 member.

According to the-preferred embodiment I re ro'vide a dust-cap48 130 gers contracting in' 't'he-move'inent of the ring which screws into the outer end of the hub- In'ernber 16, this cap having a portion 49 which operates, when the cap is screwed into place, to exert pressure against the slotted outer end of the hub-member 12 tending to outer hub-member upon the inner hub-memher, and by providing the plungers with contractible sections which are caused to contract upon forcing the plungersinto the cooperating sockets 19 in the inner hub-member, the parts of the structure may not only be caused to closely fit and be interlocked with each other against'relative movement when the parts are originally assembled, but also should the parts become worn in use. Under the .conditions last stated if no provision were made for taking up wear, sufficient relative movement of the parts would occur to produce back-lashing, and it back lashing once starts the wheel would become comparatively quickly permanently impaired for continued practical use. By my construction, lIOWBVGIQ HS stated above, it is pos sible to take up the wear and thus avoid back-lashing.
Any. suitable means for holding the ring 37 in the position to which it is rotated in the operation of forcing the plungers 21 into the sockets 19, may be provided. ivhose shown comprise a set-screw 44- which extends through an opening in a cap-member 45 surround mg the outer hub-member 16 as shown,
the positions illustrated in the drawings, the
operator grasps the handle 39 and rotates the ring 37 in clockwise direction in Fig. 2, this movement of the ring causing the cams 36 to move against the undersurfaces of the portions 29 of the plungers and withdraw the latter from the sockets 19 in opposition to the action of the springs 34, the outer ends of the cams 36 being preferably provided with portions 47 which are substantially concentric with the axis about which the ring 37 rotates, with which the plungers engage in the final movement of the ring and which operate to cause the ring to remain in the position to which it was rotated to withdraw variations in proportions of and secured to the ring 37, this set-screw havlng threaded the plungers, as stated, until ,roiated in the opposite direction by hand. From the fore going it will be noted that all of the plungcrs 21 are withdrawn from the sockets 19- by the simple operation of rotating the ring 37 and that, with these plungers withdrawn to this position, the operator may readily draw the outer hub-member 15 from the inner hub-member 12.
From the foregoing description, it willbe readily understood that a wheel constflsycted entire wheel structure besides producing objectionable noise.
While we have illustrated and described a particular construction in which our-invention may be embodied, we do not wish to be understood as intending to limit it thereto,
. as the same may be variously modified and altered without departing from the spirit of our invention, it being our intention to claim our invention as fully and completely as the prior state of the art will permit.
What we claim as new and desire to secure by Letters Patent is 1.
