The present invention relates to’ Wheels or rims and is particularly concerned with the means ‘pro vided for mounting a tire on the wheel or rim. In the present description, I have shown my inven 5 tion as applied to a Wheel, but it is obviousthat the felloe of the Wheel may be a rim. which in turn is mounted on asuitable wheel and, there fore, I wish to have it understood that the’in vention is not-limited to a Wheel and in the 1 O claims, when reference is had to either a felloe or to a rim, it is not intended that these terms 15 (01. 1152421) i- Fig; 2*isv a‘ fragmentary side elevational view of ‘the device'shown'in Fig. 1; I Fig; 3gis‘ a cross-section taken substantially alonglthe line'3é3 of Fig.1 2; ‘ Fig; 4-1is- a-vcross-section' taken substantially 5 along'thé line Iii-4 "of Fig. 3; Fig-.1 51~is~a"view ‘similar to Fig. 3 illustrating a modi?ca‘tionfof mye’invention; and ‘Fig; 6 ‘is a view similar to Fig. 2 showing a still iurther'modi?cation of=my invention. , 10 T In devices ‘of? this "character, it is very im be limited in that respect, as either may be used portantithat'the retaining?anges or side ?anges in practicing this invention without departing ‘ which abut against‘the side walls and beads'of from the scope thereof. ‘the tire 'be ?rmly held against rotation relative An - object of this invention is to providev a mounting for tires which comprises a base on 'to‘the' felloe or"~'rim',-in order that there will not 15 be :too much ‘friction’ between these ?anges and theitires ‘andin' order that there will be a proper which the tire is mounted, and which is provided with suitable‘ demountable vside ?anges to hold drivihglof‘the tire-through the intermediacy of the tire in place on the" base.

The inner diameter of the side ?ange I2 is just slight lar to locking ring I l is used to prevent the out ranged within the recess l9. ward movement of the ?ange. The rim 23 is provided with a gutter 26 in which I weld a short block 21, as by the welding shown at 28, or other wise suitably hold this block in position within In the gutter. Obviously, if desired, the equivalent The tire is ?rst placed on the rim and then the side ?anges put in place, or one side ?ange may portion of the bottom of the gutter upwardly to ly more than the outer diameter of the felloe so as to permit the side ?ange to be slipped over the felloe with the driving lug or plate I3 ar be put in place beore the tire is applied, the 10 other side ?ange being put in place after the tire is applied to the felloe, but before the tire is in ?ated. This permits the ?ange to be moved in wardly toward the central plane of the felloe in order that the locking ring I’! may be put in place. It will be noted from an inspection of Figs. 1 and 3 that the locking rings have noses 20 adapt ed to lie in an undercut portion of the groove I6 and portions 2! adapted to lie under the side ?anges l2. In order that the side ?anges will not have their inward movement arrested too soon, the recess I9 is madeof such a length as to permit the side ?anges to move inwardly a suf ?cient amount prior to application of the locking ring before the driving lug l3 strikes the end of 25 the recess. In other words, in assembling the side ring the side ring is ?rst moved to the dotted~ line position in Fig. 3 and then the locking ring ll slipped in place in the usual manner so that the nose portion rests-within the groove I6, the 30 ends l8 of the lockingring being arranged on op posite sides of the driving lug or plate I3. The side ?ange i2 is then moved to the full-line posi of this block could be formed by deforming a form shoulders against which the ends of the locking ring 25 will abut in case the ring tends to shift peripherally. On the side ?ange I secure a driving lug 29 by means of welding, such as 30, or by any other suitable means, and this corresponds to the lug E3 in Fig. 3. The driving lug is also arranged between the ends of the locking ring 5 whereby the side ?ange is held against any substantial peripheral movement. Instead of having to form a recess, such as [9, in the ?rst form of my invention illustrated, the rim may be formed uniformly throughout its entire pe riphery except that a lug, such as 21, is welded in place therein to provide an abutment. The edge of the rim, therefore, has a smooth appear ance and there is less chance of dust and dirt working in to the tire, not to mention the extra strength given to the rim by having the periph eral edge of the rim continuous instead of inter rupted as in Fig. 3. . Obviously, those skilled in the art to which this invention pertains may make various changes in 50 the particular construction and arrangement of the parts shown in the accompanying drawing tion shown in Fig. 3, either manually or under the - without departing from the spirit of this inven pressure of the side walls of the tire when the tion, and therefore I do not wish to be limited in my invention, except as hereinafter set forth in to Cl same is being in?ated. The portion 2| on the locking ring underlies. the side ?ange and is the claims. ‘ Having thus fully described my invention, therefore held‘ against upward ‘movement out of what I claim and desire to secure by Letters Pat the groove H5. The driving lug I3, which is ar ranged between the ends W on the locking ring ent of the United ‘States is: ,1. In a wheel, the combination With a rim por- -, 40 and within the recess l9, prevents substantial tion having a peripheral locking-ring-receiving movement of the locking ring peripherally rela tive to the .side ?ange and/or felloe and at the groove and a transverse driving-lug-receiving re same time prevents relative peripheral movement cess at the edge thereo_f,. a side ?ange having a driving lug extending inwardly into said recess of the side ?ange relative to the felloe. I It will be noted that with this construction the between the side walls thereof to prevent relative 145 45 inner side of the side ?ange is unobstructed and rotation between said side ?ange and rim, and the felloe is similarly unobstructed between the a split locking ring arranged within said groove, side ?anges so as to provide a satisfactory seat the ends of said locking ring being spaced apart a su?icient distance to receive said lug whereby for the tire. I - ~ said lug prevents substantial relative rotation In order to provide a means for ready removal 50 between said ring and felloe and also between of the locking ring when the tire is to be demount ed, I provide a notch 22 in the underside of the said ring and side ?ange. 2. A wheel comprising a felloe, peripheral locking ring and of sufficient width' and depth as to expose a portion of this notch 22 above the grooves inthe outer surface of said felloe adja cent the edges thereof, split-type locking rings 55 felloe, as is common in ‘rings of this nature. A adapted to be arranged within said grooves, side tire tool is inserted in the notch to lift the look ing ring out of the recess IS in the usual man ner after the side ?ange hasbeen moved to the GO dotted-line position shown in Fig. 3. Of course, it will be understood that the felloe is provided with a suitable slot for the recep tion of the valve stem of the inner tube used in the tire, as is customary in devices of this char acter. It will also be understood that other means may be used for securing the driving lug I3 to the side ?ange without departing from the spirit and scope of this invention and thatit could be made of the same piece of material as the, side ?ange. Furthermore, it will be obvious that the felloe could be a rim which is to be applied to a wheel instead of merely the felloe of the wheel itself, as it is shown in the drawing. In Figs. 5 and 6 there is showna modi?ed form of my invention in which 23 represents the rim and 24 the side ?ange. A locking ring 25 simi ?anges separate from said locking rings, driving lugs on said side ?anges arranged between the ends of the respective locking rings to prevent relative rotation between said locking rings and 60 their respective side ?anges, said felloe also hav ing depressions adjacent the outer edges thereof into which said driving lugs project to prevent relative rotation between said side ?anges and felloe within certain prescribed limits. 3. A wheel comprising a felloe having a. groove adjacent one edge thereof, a side ?ange, the outer wall of which is provided with a later ally and radially inwardly projecting lug, said felloe having a recess other than said groove for .70 receiving the inwardly projecting portion of said lug, and a split locking ring having spaced ends arranged facing the sides of said lug, the locking ring also being arranged in said groove to hold said side ?ange in place. 2,105,829 4.

A rim comprising a base portion having a 6.
