EDWARD H. KOKEN, OF AKRON, OHIO.
To all whom it may concern Be it known that I, EDWARD H. KOKEN,
. a citizen of the United States, residing at Akron, in the county of Summit and State 'provements of Ohio, have invented new and useful Imin Vehicle Wheel-Rims, of which the following is a specification.
This invention relates to improvements in vehicle wheel rims of the type adapted to hold an elastic or cushion tire, and the object of the invention is, broadly speaking, to provide a rim which will securely hold an elastic tire in its proper seat on the rim and simultaneously contract or place a tension upon the base portion of the tire with ,a view. of increasing the longevity of the tire and its general effectiveness. The contracting or compressing of the base, also serving to prevent the unintentional dislacement of the tire and the danger of its iieing torn from its position on the rim.
The invention further contemplates pro- 'viding the tire-carrying rim at one side with an inturned clencher flange of the ordinary type and providing the opposite side of the rim with an inclined face. Cooperating with the inclined face is a split annular,
contractible, tire-retaining band with its outer portion shaped to engage the lateral beading at one side of the tire and with an inner lateral portion adapted to engage the inclined side face of the rim in such a manner that as the band is drawn inwardly, and transversely toward the tire it will contract and draw down the free side of the tire to compress or distort the base thereof and place the same under tension. At the same are as the tire is moved laterally on the outer face of the rim by the movement of the contractible band the bending on the. opposite side will be forced laterally under the overhanging clen her flange, this movement serving to force it inwardly and compress; the base portion of the tire adjacent to the flange so that the entire base of the tire is placed under tension.
lVith the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of the parts constituting the invention to be hereinafter specifically described and illustratedin the accompanying drawings Specification of Letters Patent,

which form a part hereof'wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.
In the drawings in which similar reference numerals indicate like parts of the different figures, Figure 1, is a transverse sectional view of the rim portion of a vehicle wheel showing a tire mounted thereon and the tire-holding means in the position which it assumes during the seating of the tire; Fig. 2, is a similar view showing the tire held in position by the tire-holding means in position which it assumes when completely seated on the rim; and, Fig. 3, is a transverse sectional View of a rim adapted to carry a dual tire with twin tires seated thereon. 7
Referring to the drawings in detail, the reference numeral 1 indicates the felly of avehicle wheel provided with alongitudi nally-extending series of transverse openings 2 in which are mounted bolts 3 for a purpose to be later described. Mounted on the felly l is a felly-band 4. Mounted on the felly-band 4 is a tire-carrying rim 5 provided at one side with an inturned clencher flange of ordinary construction and the opposite side of the band is provided with an inclined portion 7. Cooperating with the inclined portion 7 is a split retaining ring 8 provided with a hook-shaped outer edge 9 for engagement with the tire and with a laterally-inclined portion 10 adapted to engage the inclined face 7 of the Mounted on the rim 5 is an elastic tire 11 provided with a plurality of spaced t1ansversely-extending wires 12 arranged in the base thereof. The tire is preferably provided with an inclined shoulder 13 on each side ofthe base. I prefer to form the ends of the cross-bars 12 which engagethe clencher flange 6 with a cut-away portion ll to lie flush with the shoulder 13 on that side of the tire.
It will be obvious that if the split ring 8 contracted by being forced laterally toward the tire it will force the inclined ends of the bars 12 againstthe inner face of the clencher flange 6 and thereby force the bars and tire base inwardly toward the rim 5 and at the same time, as the ring 8 moves to the left in Figs. 1 and 3 it will be contracted and draw inwardly the side of the tire which it engages. I
In order to shift the split ring laterally l provide an annular band 13 provided with apertures to receive the bolts 3 and provided with a laterally-extendiug portion 16 which carriesat its outer end an outwardly extending flange 17 which engages the split ring 8. As the nuts 18 on the boits 3 are drawn up the parts will assume the position shown in Fig. 2 with the cross bars 1'2 forced downwardly in the position shown in Fig. 2 thereby placing the base portion of the tire under tension.
It will be apparent that by employing a rim provided on one side with a rh-nrher flange such as is shown in Figs. 1 and '2 the necessity for split rings 8 on both sides of the tire are obviated and the weight of the vehicle wheel and the expense of constructing the same are considerably reduced. It Will be further apparent that if it is desired to construct what is known as a dual tire, that is to sa two tires mounted on a single Wheel rim, iflicult'ics will ordinarily be experienced in retaining the opposing beads of the tire along the central line of the rim, but by using the device in the construction shown in Figs. 1 and 2, these dilliculties of securely holding the inner opposing side faces of the two tires on the rim is eliminated.
In Fig. 3, the two tires are designated by the reference numerals 20 and '21 and are mounted in rims respectiu-ly designated by. the reference numerals 22 and 2 5 provided with transverse cross-bars if. These rims 22 and 93 are mounted on a wide fared tellyband 25 mounted on a fully '26 through which extend bolts 27. In positioning these rims 22 and .23 on the l'elly-baml :25 the clencher flanges will oppose each other and lie in contacting engagement and the outer inclined portions 2% of the rims will he rc versely arranged. The outer lateral portions of the two tires are held through the medium of broken retaining rings 30 drawn into position through the medium of lateral clamping rings 30 the same as has been described with reference to Figs. 1 and 2. By this construction two similar ti res may be mounted on a wheel rim and either of the tires may be removed or replaced a t pleasure without interfering with the other. and at the same time, all the advanta es obtained by the constriu-tion shown in l' l and 2 are secured and the laterally opposing portions of the bases of the two tires are se curefv held against movcuuait. 1
