DEMOUNTABLE WHEEL RIM.
Application filed January The principal object of the invention is to facilitate the changing of tires on demountable wheel-rims.
Other objects will appear in connection with the following description.
Fig. l of the drawings is a view in side elevation of a demountable wheel-rim embodying my invention, and shown partly broken away andin vertical section.
Fig. 2 is a horizontal section of the same taken on the broken line 2-2 in Fig. 1.

Fig. 5 is a central vertical longitudinal section of the same taken on the broken line 5-5 in Fig.4;
Fig. 6 is a view similar to Fig. 1. of a demountable wheel-rim showing a modified form of the invention, also showing partly in side elevation and partly in longitudinal central section a turnbuckle adapted to be used for spreading and also for drawing together the ends of the larger segment of the mm.
Fig. 7 is ahorizontal section of the same taken on the broken line 7 7 in Fig. 6.
Fig. 8 is a similar section taken on the broken line 88 in Fig. 6.. i
Fig. 9 is a plan view of the inner side of the smaller segment of the rim detached.
Fig. 10 is a central vertical longitudinal section of the same taken on the broken line 10-10 in Fig. 6.
Referring to Figs. 1. to 5 inclusive of the drawings my improved demountable wheelrim is made up of two segments, 1 and 2, the segment, 1, comprising a much greater are than the segment, 2.
The segment, 1, is made of resilient metal permitting its ends to be forced apart or forced together as occasion may demand in changing tires.
I have shown the clincher type of rim. but
.the cross sectional. form of the rim is immaterial for the purposes of the present invention, andthe sides may be straight instead of guttered if desired.
The side portions of the two segments, 1 and 2, abut against each other end to end along inwardly convergent lines, 3, as shown in Fig. 1, forming at each end of each segment mutually abutting surfaces which pre 22, 1926. Serial No. 83,087.
vent inward displacement of the smaller segment, 2.
The smaller segment, 2, has at each end of its body portion a tongue, l, which laps on the inner side the neighboring end of the body portion of the larger segment, 1, forming mutually abutting surfaces which prevent outward displacement of the smaller segment, 2.
These mutually abutting surfaces are preferably formed by bevelling the outer surfaces of the tongues as shown at 5, and
by similarly bevelling the inner side of the body portion of the larger segment as shown in F 1, whereby the lap-joint formed by the tongue, 4:, and the lapped portion of the body of the segment, 2, is maintained of the same thicki'iess as the body of the rim, and within the normal cross-sectional dimensions of the rim.
The smaller segment, 2, is thus interlocked at each end with the respective ends of the larger segment, 1, by integral interengaging means whereby displacement of said smaller segment, 2, either inwardly or outwardly is prevented.
With the segment, 2, thus inserted be tween, and interlocked with, the ends of the segment, 1, a complete rim is formed adapt ed to support a pneumatic or other tire in the usual manner.
The tire when applied to the rim forms an additional means for holding the two seg ments together it closely encircles the body of the rim and tends to prevent expansion of the segment, 1, which is necessary to release of the segment, 2, because to release said segment in an inward direction the ends of the segment, 1, must be spread apart a suflicient distance to release the lock formed by the convergent mutually abutting surfaces along the convergent lines, 3, while to release said segment in an outward di rection the ends of the segment, 1, must be spread apart a sufficient distance to release the lock formed by the mutually abutting surfaces of the tongues, a, and the ends of the segment, 1.
When the rim is secured in place upon a wheel the circumferential portion of the wheel forms an additional protection against inward displacement of the segment, 2.
The operation of the device is as follows:
To apply a tire to the rim, the segment, 1,
is expanded in any known manner until the lock formed by the tongues, 4, is "released whereupon the segment, 2,'can be outwardly withdrawn.
The segment, 1, is then contracted by any suitable means to permit the tire to be readily applied thereto, the tire being at the same time applied to the segment, '2, which will temporarily occupy a somewhatoutwardly displacement position.
After the tire has been thus applied, the segment, 1, is again expanded until the tongues, 4, on the segment, 2, can be passed between its ends. V
The segment, 1, is then permitted to contract to normal position interlocking the tongues, 4, withthe ends of the segment, 1, and completing'the rim formation.
The tire is then inflated and the device is ready to be applied to a vehicle wheel in the usual manner.
If preferred, the segment, '1, may be expanded to a greater degree suflicient to release the lock formed by the mutually abutting surfaces along thelines, 3, a'fiording abutment room for applying the segment, 2., to the tire which has already been applied to the segment, 1, in which case all that is necessary is to maintain the ends of the segment, 2, in position to properly abut against the neighboring ends of the segment, 1, as the segment, 1, ispermitted to contract in order that the tongues, 4, shall properly engage the inner sides "of the neighboring ends of the segment, 1.
To'rernove the tire, the segment, 1, is expanded by any suitable means until the lock formed by the mutually abutting surfaces along the lines, 3, is released, whereupon the segment, 2, can be released from the tire and removed by inward displacement. I The segment, 1, is then contracted sufiiciently to permit the tire to be easily removed 'there from. v
The construction shown in Figs. 6 to 10 inclusive is the same'in all respects as that above described, except that the body portion'of the segment, 2*, 'and the neighboring ends of the segment, i are each formed with a plurality of "tongues, 6, on the segment, 2 and 7 on the segment, 1 Alternate tongues, G, on the segment, 2*, lap on the outer side respective tongues, 7, on the segment, 1, and the other tongues on the segment, 2"-, lap on the inner side the respective other tongues on the seg ment 1 7 The mutually abutting surfaces on these respective tongues are preferably beveled whereby the combined thickness of two mutually lapping tongues is not greater than the thickness of the body 'of the rim.
Mutually abutting surfaces on these 're spective tonguesthus prevent both inward displacement and outward displacement of the segment, 2, and the tongues by sidewise engagement tend to hold the two segments in circular alinement.
I have shown in Figs. 6 and 7, a convenient form of turnbuckle for use in expanding and contracting the segment, 1, for the purposes above set forth.
This comprises a nut member, 8, and right and left hand screw threaded members, 9 and 10, each of which has on its outer end a hook, 11, formed with two prongs adapted to respectively engage two holes, 12, formed in the body portion of the segment, 1, a short distance from each end of said seg 'ment but any rim exanding'and contracting mechanism may beused. r
In bevelling the ends of the segment, 1, to receive the bevelled tongues, 4, of the segment, 2, channels are formed on the inner side of the body portion of the segment, 1, within which channels said tongues, 4, are seated and the side walls of these channels and the side walls of the tongues are thus formed with mutually abutting surfaces which prevent "lateral displacement of thesegment, 2. r
The two segments may be provided in any known manner with mutually abutting sur faces to prevent lateral displacement of the segment, 2, but I prefer to obtain this resuit by bevelli'ng the tongues, 4, and the seats therefor in the segment, 1, as by such a 'construction the engaging portions of the two segments are confined within the normal cross-sectional dimensions of the rim.
1 do not wish to be limited to the constructions shown and above described, as, for certain purposes of the invention, various changes may be made'in the form and arrangement of various parts of the device 7 without departing from the spirit of the invention.
What I claim as new and desire to'secure by Letters Patent is l 1. A 'demountable wheel-rim comprising two separable substantially uniform segments neighboring ends of which have oppositely inclined side portions with matually abutting surfaces to prevent inward displacement of an end of one segment, the said portions being substantially continuous at their lines of junction, said end of said to prevent lateral displacement of the ends of one segment relatively to the ends of the other segment.
3. A demountable Wheel rim comprising tWo separable segments abutting each other end to end, and having lapping portions mutually abutting to prevent of themselves both inward and outward displacement of each end of each segment relative to the l neighboring end of the other segment, said lapping portions having mutually abutting surfaces serving also to prevent lateral displacement of the ends of one segment relatively to the ends of the other segment, and said lapping portions being so formed as to be confined Within the normal cross-sectional dimensions of the rim.
In testimony whereof, I have hereunto set my hand this 16th day of January, 1926. FRANCIS H. WAGER.
