VEHICLE WHEEL.

To all whomz'tmay concern:

Be it known that I, LEWIS IRVINE THOMPSON, a citizen of the residing atv Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Vehicle 'Wheels, of which the following is a specification, reference being had therein to the accompanying drawings.

Thisinvention relates tovehicle-wheels of the type in which the spokes or other weight-sustaining membersbetween the hub.

and felly are arranged-in opposite bracing relation on each side and maintained under tension. 1 i I It is an object generally to improve that type of wheel, and particularly to provide therein eflicient, comparatively simple, and easily-operable means for adjusting simulta-neously the tension of theweight-sustain ing members at the hub and torealign: the parts when they have become displaced in SeI'VlCe.

The invention is applicable not only to' wheels having spokes, but also to those whose weight-sustaining members are of disk form.

When considered in connection with the description herein, the characteristics of the 0 invention will be apparent from the accompanying drawings, forming part hereof, wherein are disclosed, for purposes of illustration, weight-sustaining elements of. lattice form, each of which elements consists of tangentially-disposed spoke members produced integrally from a single piece of sheet metal. 1

Although the disclosures herein exemplify whatnowis considered to be a preferable embodiment of the invention, it is to be understood that it is not the intention to be limited necessarily thereto in interpretation of the claims, as modifications and adaptationswithin the limits of the claims can be made without departing from thenature of the invention.

Like reference-characters refer to corresponding parts in the views of the drawings, of which- Fig. 1 is an elevation of the wheel;

Fig. 2 is an end view of the hub';

Fig. 3 is a side viewof the hub,

Fig. 4 is a diametrical section of the wheel; 1'

on the inner annular end of a hub 12.

The hub is formed in the opposite end portion with radially and longitudinally disposed guideways 13, which are uniformly spaced and of equalsize and open to the periphery and outer end of the hub.

Key portions 1 1 ofa tension member" 15 fit snugly in and are movable axially inthe guideways 13. The tension member thus is splined on the hub, and it is fitted thereon with just suiiicient clearance as will permit it to betilted from its normal plane pers pendicular to the axis of the hub. The tension member has an annulus 16, to the outer side of which is connected the outer-weightsustaining member or members 9 by bolts, machinescrews, or other suitable fasteners 17.

Theouter terminal portion of the hub is of smaller size than the adjacent part there of containing the guideways 13, and on that terminal portion is an annular member 18, which is positioned against the larger end of the: hub, that end constituting an abutment for the member 18.

Independently-rotatable draw members 19, preferably in the form of bolts, extend through the member or ring 18 with their heads against the outer side thereof and with their threaded shanks extending into threaded seats in thekey portions of the tension member. 1

The arrangement of the parts is such that, when the draw members 19 are rotated, the tension member 15 is moved axially ofthe hub and the tension ofthe weight-sustaining members increased or deof tension is torbe effected in a wheel that is alined 'or true, the tension member during axlal movement 1s maintained 1n its,

normal plane substantially perpendicular to the axis of the hub. It, however, it is necessary to realign the wheel 'atter parts have become displaced trom normal, "or it tor any other reason it is desired to throw the weight-sustaining members into uneven tension, the draw members may be given more rotation at one place than at another, so that the tension member is tilted trom normal position to an extent sufficient to accomplish the purpose desired.

As the heads of the draw members are accessible at an end ot the hub, adjustment or variance of tension or alignment may beeitected easily with-out removal ot the Wheel from the axle orremoval ot'part's'ot the wheel.

The invention is exemplified herein" in association with load-sustaining members of with said telly.

- member,

lattice torm 'produced iby stamping "out of sheet-metal stock of suitable thickness 1 and strength and possessing'the quality of givor bending to an extent sufficient to movable tension member splined thereon,

an annular member on the hub, draw members independently rotatable in said annular member arranged to adjust said tension member axially, a telly, a weight-sustaining member connected with said telly'and tension and another weight-sustaining member connected at another place on said hub and with said telly.

2. A wheel comprising a hub having longitudinal guideways therein open to one end, an axially-movable tension member having key portions disposed in said guideways, an annular member at the open ends of said guideways, draw members independently rotatable in said annular member arranged to adjust said tension member axially, a telly, a weight sustaining member connected with said telly and tension member, and another weight-sustaining member connected at another place on said hub and 3. A wheel having a hub having an end abutment and longitudinal guideways open at their ends to the outer side of said abutment, an axially-movable tension member having key-portions disposed in said guideways, an annular member against said abutment, draw members independently rotatable weight-sustaining member connected at another place on said hub and with said telly.

A wheel comprising a hub, an axiallymovab-le tension member splined thereon having threaded seats, an annular member on the hub, bolts rotatable in said annular member having threaded shanks disposed in said seats arranged to adjust said tension member axially, a telly. a weight-sustaining member connected with said telly and tension member, and another weight-sustaining member connected at another place on said huband't'o said telly.

5. A wheel comprising-"a hub havinga r'educed end portion and longitudinal guideways in the larger portion thereot,=an axially-movable tension :member having key portions disposed in said guideways and having also threaded seats, an annular member on the reduced end of the hub seated against the wall ot-the larger portionthereof, bolts rotatable in said annular member having threaded shanks disposed in said seats arranged to adjust said tension mem ber axially, a telly, a weight-sustaining member connected with said telly and tension member, and another weight-sustaining member connected at another place on said hub and withsaid telly.

6. A wheel comprising a hub, an axiallymovable tension member splined thereon having an annulus, an annular member on said hub, draw members independently rotatable in said annularmember arranged to adjust said tension member axially, a telly, a weight-sustaining member connected with said telly and annulus, and another weightsustaining .member connected at another place on said hub and with said telly.

7. A wheel comprising a hub having an end abutment and longitudinal guideways open at their ends to the outer side of said abutment, an axially-movable tension member having key portions disposed in said guide ways and threaded seats an'dan annulus, an annular member against said abutment, bolts rotatable in said annular member having threaded shanks disposed in said seats arranged to adjust said tension member axially, a telly, a weight-sustaining member connected with said telly and arr nulus, and another weight-sustaining member connected at another place on said hub and with said telly.

8. A wheel comprising a hub, an axiallymovable and tiltable tension member splined thereon, an annular member on said hub, draw members independently rotatable Bin said annular member arranged to adjust said tension member both axially and tiltably, a felly, a Weight-sustaining member connected with said felly and tension mem her, and another weight-sustaining member connected at another place on said hub and With said telly.
