Abstract
Abstract A belt including a main body formed in to an endless configuration with a plurality of substantially equally pitched approximately round shafts embedded in the main body. Also included are a plurality of wires engaged along nearly an entire lengthwise portion of each of the shafts. The wires can be interlaced with the shafts or wound on the shafts and the wires cna be a twisted thread of organic fiber, inorganic fiber, or glass fiber. The main body can be made of rubber of high rigity having a longitudinal elastic coefficient of approximately 10-140 kg/mm 2 . The main body could also be made of refractory synthetic resin having a longitudinal elastic coefficient of 5-150 kg/mm 2 . Each shaft can be of substantially the same diameter along its entire length.

Claim 1
Independent Claim
84 words
A belt comprising: a main body including a first plurality of cogs defining an upper surface and a second plurality of cogs defining lower surface with said body formed into an endless configuration; a plurality of substantially equally pitched approximately round shafts with each shaft disposed between an upper surface cog and a corresponding lower surface cog; and a plurality of wires interlaced with said shafts in such a manner that each shaft is positioned at a portion at which two adjacent wires intersect.
Claim 2
Dependent Claim
84 words
A belt comprising: a main body including a first plurality of cogs defining an upper surface and a second plurality of cogs defining lower surface with said body formed into an endless configuration; a plurality of substantially equally pitched approximately round shafts with each shaft disposed between an upper surface cog and a corresponding lower surface cog; and a plurality of wires interlaced with said shafts in such a manner that each shaft is positioned at a portion at which two adjacent wires intersect.
Claim 3
Dependent Claim
96 words
A belt comprising: a main body having an upper surface with a first plurality of cogs and a lower surface with a second plurality of cogs and formed into an endless configuration; a plurality of equally pitched round shafts each of which is located between each upper cog and the corresponding lower cog thereto; a plurality of wires interlaced with the shafts in such a manner that each shaft is positioned at a portion at which two adjacent wires intersect; and sail-cloth means for covering the upper surface and the lower surface of the main body.
