‘Patented July 5, 1938 2,123,025 ' _ UNITED STATES PATENT OFFICE 2,123,025 DEMOUNTABLE RIM Emanuel Ramirez, Mira?ores, Peru Application February 16, 1937, Serial No. 125,944 1 Claim. ' (or. 152-405) This invention relates to demountable rims, I which normally rest in angular recesses 24 in the and more particularly to a combined wheel and inner face of the felly It so thatwhen nuts 25 are screwed on to the outer ends of the bolts 22 demountable rim section which enables the re moval and replacement of a tire in a minimum 5- of time. and against the ring i'l, all the parts will be se curely secured together and when these nuts are 5 removed the ‘partsmay be separated to permit, ' The invention embodies many novel features of construction and combinations and arrange ments of parts, all of which will be more fully hereinafter described and pointed out in the . In the accompanying drawing- ' the removal and replacement of a tire. ' 10 claim. ‘ Fig.1 is a view in side elevation of my im proved wheel and demountable rim, the outer cap or cover being removed; ' l5 , Fig. 2 is a view in transverse section on the line 2--2 of Fig. l with the cap or cover in op In order to bridge the gap of the recess IS in the felly, I‘ provide an annular ring or hoop 28 which is located within the tire and fits around 10 the outer face of the felly, This hoop 28 is pro vided with an opening 21 to receive the valve of the tire, and the felly i0 is provided with a re cess 28 which also accommodates the valve of _' the tire and permits the removal of the tire. i5 28 represents a cap or removable cover plate which is preferably of general concavo-convex Fig. 3 illustrates in section the several parts of shape and is provided at its outer edge with an inwardly turned portion constituting a bead l0 ., my improved wheel and demountable rim; and 20 Fig. 4 is a fragmentary view in section, the view which is adapted to spring into the bead It on 20 being taken through the recess portion of the the rim section I! and be'retained within the rim section but can be easily removed by the in wheel felly which receives the telly of the tire. My improved wheel includes a felly III, which, sertion of a proper tool through a recess ii in may be connected. by spokes ii with a central the disk 29. While I have illustrated and described what I 25 25 hub l2, although, of course, it is to be understood that the invention is not limited to this type of believe to be a preferred embodiment of my in wheel as any form of wheel having spokes or vention, it is obvious that various slight changes erative position; disks of other construction may be employed. a The felly III is made with an annular groove or 30 recess It so that the felly is of general channel shape in cross section to lighten the weight of the wheel as much as possible. ' Av fixed rim section I4 is secured to or made integral with the inner portion of the felly, and - 35 a removable rim section II is located against the outer face of the ,felly and at its outer portion is of general compound curvature in section con forming in general shape to the ‘shape of the fixed ' ‘ rim section I‘. With this exception,v however, 40 the outer rim section II has its outer edge turned ' inwardly forming an annular internal bead l6. l1 represents a ring which is located within ‘ the rim section I! and hes ?at against the inner portion of said- rim section and conforms in 45 curvature to the outer portion of the rim section so as to lie ?ush against the rim section through out. This rim section i5 is formed at its inner edge with an annular inwardly projecting ?ange ll located within the felly l0 and against the in 50 ner face of the felly. ‘ ‘ The felly Ill, the rim section II, and the ring I‘! are formed with registered openings I8, 20 and 2i respectively receiving bolts 22. These bolts 22 have angular heads 23 at their inner ends may be made with regard to- the form and ar- , rangement of parts without departing from my invention, and hence I do not limit myself to the 30 precise details set forth but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the claim; . a I claim: ' 35 In combination with a wheel, a channel shaped felly constituting an integral part of the wheel, a rimsectionintegral with the inner ?ange of the wheel felly, a removable rim section located against the outer face of the wheel felly, a re- 40 movable tire supporting hoop located around the telly between the rim sections, a ring located against the outer face of the removable rim sec tion, an annular ?ange on the removable rim section located within the'wheel felly, said felly, 45 removable‘ rim section and ring having ,alined openings therein, bolts in said openings, and nuts on the bolts clamping the parts together, said bolts having angular heads at their inner ends and said felly having angular recesses in ‘0 its inner face receiving the bolt heads and pre venting turning movement of the bolts when the nuts are turned thereon.
