To all whom it may concern i '1 Specification of Letters Patent.

a citizen of .the United States,v residing, at

F-ulda, in the county of Murray: andState of Minnesota, have invented a new and useful Tire-Fastening Means,

lowing is a specification.-

One object of the present invention -to provide novel means. for holding; the longitudinal edges of a :tire nterlocked with a With the foregoing and other objects in view, which will appear as -the description proceeds, the invention resides in-the combi-- nation and arrangement of parts and in the of which the foldetails of constructionhereinafter described" and claimed, it being understood thatchanges in'the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing fromthe spirit of theinvention.

In the accompanying draWings,.Figure 1 shows in sectional side elevation, a portion of a wheel equipped with the device constituting the subject-matter of this application; Fig. 2is a transverse sectionof the structure shown in Fig. 1, the cutting plane being passed along the line A'B of Fig. 1; Fig. 3 is a perspective of one of the tire sections; Fig. 4 is a perspective of the tire-retaining member.

In the drawings there is shown a rim, de-

. noted generally by the numeral 1, the same comprising a felly 2 and a felly band 3, the felly band 3 having clencher ribs 4. The tire is preferably fashioned from resilient metal and comprises'a plurality of trough sections 5 having at their ends, projecting tongues 6. Considering each section 5 as a unit, the tongues which are upon the opposite ends of. each section alternate with each other circumferentially of the tire. When one section 5 is assembled with another like section, the tongues of the adjacent sections will alternate with each other Owing to this construction,the desired'play of the meeting ends of the sectionsb will be afforded, and at the sametime, the tire will be of great strengthat the meeting ends of the sections. The sections 5 are equipped. at

engage with the clencher ribs of th'e'felly band 3. i

The invention further includes a; pair of tire-engaging membersS which may be sev-f ered rings, restingf uponthe felly jband 3 i the members Shaving inclinedouter faces 9 adapted to engage the sections5to'holdthe flanges 7 engaged 'witl1 tlie 'clencher ribs 4:1

The inner faces of the tire engagingi mombers 8 51am; toward the'median plane oft-he wheel and toward the hub of the wheelfas indicated at 10. q i

The invention further aplural- I ity of tire-retaining' members 1 1', of which tire-retaining members there may be any number. The tire-retaining inember H' is preferably in theform of a plate provided at its edges with diverging flanges 12 adapted to engage the faces 10 of the tire-engaging members 8;

' Extended through the tire-retaining member 11, and if desired, rigidly connected therewith, is a bolt 14 which passes through the felly band 3 andthrough the felly 2, there being a nut 15 upon the bolt 14, which nut engages the intrados of the felly 2. Pins 17 or other projections extend from the folly band 8, the pins 17 engaging in slots 16 formed in the body portion of the tire-retaining member and extended through the flanges 12 thereof.

' Presupposing that the parts are positioned as shown in Fig. 2 it will be observed that by loosening the nut 15, the bolt 14: may be moved toward the periphery of the tire, carrying with it the tire-retaining member 11, the hold of the tire-retaining member to permit the clencher flanges 7 of any desired section 5 to be disengaged from the clencher ribs 1 of the fe'lly band 3, whereupon any desiredsection 5 may be disengaged from the adjoining sections, to permit the renewal of a defective section. The manner in which the tongues 6 of the sections interengage with 1 each other has been pointed out hereinbefore. The projections l7serve to prevent the tire-engaging members 8 from moving too far in the direction of the median plane of the tire when the tirearetaining member 11 isloosened. In addition to the foregoing function, the projections 17 engage the tireretaining member when the sameis seated on the telly band 3, and serve to prevent the tire-retaining member 11 from moving circumferentially of the wheel.

As will be understood readily, when the nut 16 is tightened, thefianges 12 of the tire-retaining member llwill engage with the faces 10 of the tire-engaging members 8, forcing the members 8 laterally until their faces 9 engage with the sections 5 and into engagement with force the flanges 7 the ribs 4. V

Recalling that the sections 5 are fashioned from spring metal, it is obvious that the a wheel will possess the desired resiliency, and

i at the same time, the possibility of a, punc- I Copies of thil patent may be obtained for a tire'having its edgesinterlockedwith the ribs and located between the ribs and the hands; a tire retaining =stri p bearing against the inner edges of the bands to hold the latter in contact with the tire; and a securing element uniting the strip with the rim; the strip having elongatedtransverse openings and the rim having pins which engage in the openings to hold the strip against creeping, the strip being removable from the pins and the pins lying hetweenthe securing el'e mer t-and, ribs .andinthe path of the bands, thereby to limit themovement of the latter toward the median plane of theflrimwhen the strip is removed from thepins. v
