Abstract
Abstract A structure of annular form, fabricated of arcuate sections fastened together, is mounted within a tire and supported with respect to the rim thereof out of engagement with the periphery of the tire a distance sufficient to allow normal deflection of the tire, the device coming into operation to prevent the breaking of a tire casing upon loss of a predetermined amount of pressure in the tire or in the event of the puncturing or blowing out of the tire, the device thus carrying the load of the vehicle until the tire can be changed or suitable repairs made thereto.

Total Claims: 4
Claim 1
Independent Claim
233 words
An inner support for a tire mounted on a one-piece rim comprising an annulus within the tire, said annulus being made up of a plurality of circumferentially complementary sections each of which comprises a generally radial load supporting member and a rim at the radially outer extremity thereof and fixed thereto, said rim being spaced a distance from the tread portion of the tire to allow for normal deflection of the latter but to limit inward movement of the tire if deflated to a predetermined extent, said supporting member detachably engaging the rim and being fixed against lateral movement relative thereto, means for fixing said sections to each other, comprising circumferentially oriented lugs carried by said load-supporting members adjacent the ends thereof, a screw passing through each lug adjAcent one end of each section and threaded into the adjacent lug of the next adjacent section, said sections having their ends slightly spaced whereby, when said screws are tightened, said annulus is contracted to cause a wedging of the radially inner edges of said load-supporting members with the rim and means cooperating between said rim and said load support members to prevent circumferential movement of said annulus, each load-supporting member provided with a radial screw having radial threaded connection therewith, said screws being adapted to be tightened against the rim after said sections have been drawn together to their limit by said first-named screws.

Claim 3
Dependent Claim
162 words
An inner support for a tire mounted on a one-piece rim comprising an annulus within the tire, said annulus being made up of a plurality of circumferentially complementary sections each of which comprises a generally radial load-supporting member and a rim at the radially outer extremity thereof and fixed thereto, said rim being spaced a distance from the tread portion of the tire to allow for normal deflection of the latter but to limit inward movement of the tire if deflated to a predetermined extent, said supporting member detachably engaging the rim and being fixed against lateral movement relative thereto, means for fixing said sections to each other, and means cooperating between said rim and said load support members to prevent circumferential movement of said annulus, each load-supporting member being radially planiform, and a resilient band spanning the outside of certain of said sections in engagement with the tire and having end portions extended radially inwardly and welded to said load support.
