(Cl. 152-411) This invention relates to vehicle wheel rimsof “the character employing a gutter at one edge thereof and a detachable tire retaining ?ange in ‘ the form of an endless ring mounted in the gutter. 5 ‘The principal object of this invention is the pro ?ange E3 in the gutter i2. ‘ This consists in swedging or cutting away a portion of the inner edge of ?ange it ‘to provide a relief i8 of limited vvision of'a novel gutter and side ?ange construc tion permitting the mounting and demounting of is provided with a demounting slot or recess IQ for the reception of a prying tool. While the slot the ?ange, notwithstanding the fact that the in ernal diameter of the ?ange is less than the dis tance‘ from the top of the gutter at onelside of the rim to the bottom of the gutter. at the dia metrically opposite side of the rim. is is located substantially diametrically opposite from the relief l8, it is intentionally located ap proximately 12 degrees from a point i811 directly 10 opposite therelief i8 on the center line i8a of relief 18. As here shown, the slot i9 is located in ‘ An illustrative embodiment of the invention is shown in the accompanying drawing, wherein Figure 1 is a side View of a tire retaining ?ange ‘embodying the present invention; ‘20 circumferential extent. 7 ‘ Substantially opposite the relief it the ?ange a zone which is spaced more than 145 degrees and ‘less than 180 degrees from the center of relief [8. The slot is as best shown in Figure 4 is inclined both radially and axially. The radial inclination Figure 2 is a side view of a wheel rim having is toward the adjacent circumferential extremity the tire retaining ?ange of Figure 1 mounted of relief l8, as clearly shown in Figures 1, 2 and 5. The extent of both the radial and axial in clination is of importance, although they may be varied to some extent. Preferably the surface indicated at lQa is inclined approximately 60 degrees from a vertical plane. ‘The extent of the radial inclination of recess i9 is preferably such that it would form an angle of approxi thereon; ‘ Figure 3 is an enlarged fragmentary sectional View taken on substantially the line 3-—3 of Fig ure 2; “ Figure 4 is an enlarged fragmentary side view of the ?ange shown in Figure 1; 25 Figure 5 is a sideview illustrating the position of the ?ange‘and rim during the mounting of the ?ange upon the ‘rim; - . Figure ‘6 is an enlarged fragmentary sectional view taken on substantially the line 6-6 of Figure 5; and . j . ‘ Figure 7 is ‘anlenlarged fragmentary sectional view‘ taken on substantially the line 'l--‘i of Figure 5. _ p The relation of the several parts of the rim 35 embodying the present invention is best shown mately 78 degreeswith the radius of the ?ange. The importance of these inclined surfaces for slot i 9 will appear from the following description of the manner in which the ?ange is mounted upon the rim. The manner of mounting the ?ange I3 upon the rim H3 is illustrated in Figures 5, 6 and 7. As shown in Figure 6, the inner edge of ?ange i3 lying below the relief is and the slot i9 is in- ‘ serted into the gutter l2 which, as will be under 35 in Figure 3. ‘As there shown, the rim includes stood, may be readily accomplished notwith an annular tire seat Ii] having an integral tire standing the difference between the diameter of the ?ange and the gutter. As soon as the lower portion of ?ange i3 is inserted in the gutter i2 anyconventional form of prying tool is applied to the slot i9 and pressure exerted against the ring retaining gutter ii 40 cludes an retaining i) ?ange H at one edge thereof and a at the other edge. The gutter l2 in outer side wall lZa. A detachable tire ?ange i3 is mounted in the gutter I2. The heels M of a pneumatic tire are shown in the position occupied when an in?ated tire is mounted upon the rim. Conventionally the rim 45 I0 is secured to the periphery of a wheel body l5 it in a radial and circumferential direction. This pressure stretches the ?ange out of round and pulls the lower half ?rmly into the gutter so by means of rivets l6, the parts l5 and i6 being shown in dotted lines. The detachable tire retaining ?ange i3 is in is pulled over the outer wall of the gutter. As soon as the ?ange i3 adjacent the slot I9 is over the gutter wall 92a. the remainder of the ?ange may then be readily pressed into position be cause of the fact that the major portion of the ?ange is already deep in the gutter. 7 Figures 5, 6 and '7 show the relative positions of the ?ange and gutter as the prying tool is applied to the slot 89. The lower portion of ?ange I3 is engaging the bottom of gutter l2 as the form of an endless ring and its internal di ameter at the points ll--I1 is less than the dis tance from the top of the gutter wall Hot at one side of the rim ii) to the bottom of the gutter l2 at the diametrically opposite side of the rim. In view of this difference in diameters special pro 55 vision is made for mounting and demounting that the portion of ?ange i3 adjacent the slot 19 45 2 2,125,756 shown in Figure 6 while the upper portion of ?ange I3 is still located outside of the gutter. Of course, the internal diameter, of the ?ange I3 is greater than the internal diameter of the gutter l2 measuring from the bottom of the gut inner edge of the ?ange in a region remote from the relief to provide an inclined contact surface, one circumferential extremity of the contact sur face being more remote from the center of the ?ange than the other circumferential extremity. ter at one side of the rim to the bottom of the gutter at the diametrically opposite side of the rim. Consequently, when mounted as just de having a gutter at one edge thereof, a tire retain ing ?ange in the form of an endless ring mounted scribed, the ?ange I3 is loosely seated in the gut in the gutter, the internal diameter of the ?ange 10 ter and out of contact with the bottom of the gutter throughout a substantial part of the cir cumference. The ?ange ‘ is not permanently seated in the gutter as a locking and supporting ?ange for a tire until a pneumatic tire has been in?ated upon the rim Hi. When a tire is in ?ated on the rim the heel portions 14 of the tire assume the positions illustrated in Figure 3 and cause the ?ange l3 to take the position also il lustrated in that ?gure. In other words, the 20 ?ange I3 is seated upon the inner surface of side wall [2a of gutter I2 by the pressure which the in?ated tire exerts against it. 2. A wheel rim comprising an annular tire seat being less than the external diameter of the gut 10 ter, said ?ange being provided with means for mounting and demounting the same consisting of a single relief of'limited circumferential extent and a mounting slot formed in the inner edge of the ?ange in a region spaced more than 145 de grees and less than 180 degrees from the center of the relief, the circumferential extremity of the mounting slot farthest from the relief being more remote from the center of the ?ange than the circumferential extremity of the slot nearest 1. to the relief. 3. A wheel rim comprising an annular tire seat In order that ?ange l3 may properly seat upon having a gutter at one edge thereof, a tire re the inner surface of side wall [2a of gutter l2, tainingv?ange in the form of an endless ring the radially inner portion of the ?ange and the ' mounted in the gutter, the internal diameter of Wall [2a are provided with cooperatively tapered the ?ange being less than the external diam contact surfaces 20 and 2|. The inclination of eter of the gutter, said ?ange being provided with the tapered contact surfaces for these parts pref-I means for mounting and demounting the same erably is of such extent that they form'with a consisting of a single relief of limited circumfer ential extent and 7 an inclined mounting slot 30 30 vertical plane an angle of approximately 30 de formed in the inner edge of the ?ange. in a region grees. , 7 Of course, a de?ated tire is mounted upon the tire seat It! before the ?ange I3 is installed in the gutter l2, as previously described. In demount ing the'?ange l3 to permit the removal of the tire, the tire is ?rst de?ated and then the prying tool applied to slot H] to remove the ?ange. While only a preferred embodiment of the in vention has been herein shown and described, it 40 should be understood that the invention is not limited thereto, but is co-extensive with the scope of the appended claims‘ 45 I claim: 1. A wheel rim comprising an annular tire seat having a gutter at one edge thereof, a tire re taining ?ange in the form of an endless ring mounted in said gutter, the internal diameter of the ?ange being less than the distance from the top of the gutter at one side of the rim to the bottom of the gutter at the diametrically oppo site side of the rim, said ?ange provided with means for mountingand demounting the same consisting of a single relief of limited circumfer ential extent and a mounting slot formed in the remote from the relief, one circumferential ex tremity of the mounting‘ slot being more remote from the center of the ?ange than the other ex tremity, and one axial extremity of the mounting slot being more remote from the center of the ?ange than the. other axial extremity. 4. A wheel rim including a tire retaining ?ange in the form of an endless ring having a relief and a mounting slot of limited circumferential extents formed in its inner edge, the slot being located in a zone spaced more than 145 degrees and less than 180 degrees from the center of the relief, the circumferential extremity of the slot which is remote from the relief being more remote , from the center of the ?ange than the extremity adjacent the relief to provide. an inclined con tact surface between the two circumferential ex tremities of the slot having an inclination form ing an acute angle of substantially less than 90 . degrees with a radius of the ?ange passing through the remote circumferential extremity of the slot.
