To whe/171.. t 712.653/ con (fern lle it known -that l, JOSEPH G. SWAIN. n citizen ot the `United States., and a resident of' Akron., county ol Summit, intl Sta-te oit' hio, have inventefl new sind useful lmproven'ient in Pressed-Steel vWheels anti Method ot' Ll'ieliing' Sanne. of which the fcllcwingr is specilication, the principle othe invention being: herein explained and the liest inode. in. which l have conteinplate(A e plyinggj that prin iiple, so as to distinguish it from other inventions.

lhe present, in'ventioniv relating, es inclicritefl, to pre/sell steel Wheels :intl method of milking f, is particularly directedv to nn improved L vjle of Wheel, or, as is coniinonly collect; e disk wheeh together with an improved jlethocl of making the disk portion ot such vvheel. The particular ad vente ot nij.y improved Wheel are its greet strength in i'iroiportion to the amount oi' nniteif'ial nseil @intl the siini'ilicit;r of construction :intl ol :isseinblyx To the ecc-oinplishinenit of? `the foregoing and related ends, siiil invention then, consists ol the ineens hm'eiimlter fully described and particularly pointed ont. in the claims.

'l2 :i transverse section ot the riin und Wheel Shown in Fig. 6 at the point ot reception of the vulve stein.

ln Fig. l .l have shown :i metal hub ineiniich provided with :i radially eze tending ciiri'iigritenl tlainge or iii'iport This lining@ muv convcnicntljv he l'ornieil integral willi the linl member itself :intl all surfaces ol. fhe lienge are radial with iespcct to the hor l wl exis of the hub. The dish portion ot the Wheel consists of a. circular nlate or disk 3 which is provided with a series ot' corrugations el, cach corrngation increasing in tlepth and decreasing in Wiclt-h as it extends from the outer portion o the disk to the inner portion. The extreme 'inner portion 5 of `the disk 3 is formed with its surfaces radial with the exis of the disk, enti with the cor rugetions therein of the same size :ind conformation as the corrugations in the llenge 2 on the hub., thus adapting' the inner-portion of thedisk to be ebuttecl snugly aga-inst 'the corrugated llange 2, where it is retained byi means of e. second corrugated frange 6, which is removably astenetl to both the disk and the flange 2 by Ineens ot bolts 7.

lt is not broailly new to use@ corrugated disk in a. metal Wheel, lint in the present construct-ion the corrnga'tions serve the double purpose ot providing great, strength in the disk aga-instlateml strains and. of proviclnig' a driving engagement between the tlisl and the hub7 and thus removing' the driving` strziin from the bolts, which are used to hohl these members in engagement. ln my construction the driving engagement is through the contacting corrugatetl snrfaces of the dish and the flange on the hub. and the onlj,7 strain on the bolts Y is that of holdingthis surface in such engagement, which is of coursecomparatively slight. when compared with the full. torce oft the drivingA strain if it were exerted on the bolts alone. The corrugetions in Ihe disk 3 are so formed that the crest 8 and the bottoins 9 ot the corrugations stand at approximately the seine angle to the central plane et the dish and hub, entl thus resistst-ra-ins in the saine way as do the spokes of the Woven Wire Wheel. The forni oilf these corrugetions is shown in Figs. :2 t0 5, inclusive., in which the deepeningij forni of the corrugations as they extend toivnicl the center is clearly shown.

The disk member may conveniently. be ormecl either by pressing or rolling enen, ruler sheet of metal into the form which is shown, ani to secure e uniform cross-sectional thickness in the clisk l employ an initialblank which is thicker at its inner peripherv then it is at its outern Such ablanl; when worked to orm the progressively deepening corrugations 'from the outer eiitl to the inner enl will have a. pro gressive thinning of the metaly from the outer to the inner riin during these Working reo i peraions, and by proper proporiioning'if; is possib e 'bo conclude xvii-h' a corrngaed disk of nnii ,-ni cross-section, elhoueh is is not of course essenial to my construccion.

The outer periphery 'che disk 3 is radial ,tothe central plane of the disk and hub, and

'lihis porion l0 serves to support ehe iire-rerea ' tending groove 17, in 'which is received ,a

second tire-engaging flange 18,'Wliich is removable from the groove' for the mounting and disinounting of die tire.

in the forni of rim shown in Fig. 6, the tire-receiving member 2O is formed in one piece and is provided with a substantially central downwardly extending flange 2l, and with a. recess 22 formed on one side of lthis dange 2l, between it and a second shorter Hangs or projection 23. This form of rim may be very securely and snugly mounted on the disk 3 by being initially formed with the projection 23 of theproper size to slip over the disk 3, thus bringing the periphery of lie disk bei-Ween che anges 2l and 23. The entire rim 20 is then shrunk into a close engagement with the disk 3 as indicated in Fig. 6. By any Suiiable means this operation may conveniently be carried oui'l on machines such as lVest tire-setting machines which are commonly used to size and shrink rims. After lie rim is so shrunk on io the disk it is secured in chat Figs, 1Q and 1l l have show/vn this method of mounting the rim upon he disk, the rim "rst being; 'formed of a size so permiil the. projecion 23A to slide past `.the ouer edge of the disk 3. Upon che shrinking of the rim, es indicated in Fig. 1l, the: disk is en-l' gag-ed between the flange 2l and the flange 23 and is securely held chere-inu Y In is oi' course necessary to provide fortlie valve stem the pneumatic inner `libe of the. tire and such means are provided for the Wheel slioivn. inl Fig'. l in *che manner indicated in Figs. 7, 8 and 9. nthese igures, it is shown tha the rim membersll and l2 are provided with semi-circular registeringopenings 30 s'nd El, which iogeiher forni a circular opening' for receiving Tthe velve. as indicaed in 9. lll on the riin members li end lf2, respecively, are similarly formed izo provide semicylindrical openings, While disk 3 is cui moy io form a recess {i2- Which is consider position by e series of rives 24 or other suitable means (not shown). ln.

W Y compressing said lne flanges i3 and ,Y Medel@ ably larger than the velveI stein and permis oi convenient access and nianipulaiion thereof; ln F l2 have shown a single 34. which is formed directly through the single rim member Q0, the disk 5 being cnn enfay, :is in preceding conssruction, to prol vide a recess' 35,

The/advantages of my improved wlieei. are its simplicity of construction, its snpyporting strength, which is secured by ilie corrugai-ingoil the disk portion 'to bring the metal into a series oi* planes, some oi *which lie oneech side of the ceniral plane oil he Wheel, as well as the convenient method of manufacture. l.
