In a preferred form, said positive belt contact is achieved by the establishment of an intermeshing drive between the driving and driven cones and their respective cooperating additional cones, between which cones the belt is nipped and urged through its lengthwise movement which results in the transfer of power from the driving cone to the driven cone.，下面是Infinite speed drive专利的具体信息内容。

权利要求

1. An infinite speed drive including a motor-powered driving cone, a driven cone oriented 180* out of phase with and operatively arranged to be powered in rotation by said driving cone, an endless pulley belt entrained about said cones to provide said powering drive therebetween and to provide a speed of rotation in said driven cone which is a function of the position of said endless pulley belt along the lengths of said cones, and pulley belt-positioning means comprising a first and a second idler cone mounted respectively adjacent said driving and driven cones and movable into an operative position adjacent thereto bounding a clearance therebetween of a progressIvely increasing extent so as to urge said pulley belt in movement along said driving and driven cones in the direction of increased size of each said clearance, said idler cones being oriented in 180* out of phase relation to each other to correspondingly provide said clearances of progressively increased size in opposing directions for inducing pulley belt movement relative to said driving and driven cones also in opposing directions therealong, offset shafts respectively rotatably supporting said idler cones, and control means for rotating said offset shafts in coordinated relation such that at any one time only a selected one of said idler cones is providing pulley belt-positioning service, whereby said pulley belt is readily shiftable along said driving and driven cones into an operative position providing any desired output rotational speed in said driven cone.

2. An infinite speed drive as claimed in claim 1 wherein said control means includes means effective to simultaneously move one said idler cone closer to, and the other idler cone further away from, said pulley belt-interconnected driving and driven cones.

3. An infinite speed drive as claimed in claim 2 wherein said driving cone and one said cooperating idler cone, and said driven cone and said other cooperating idler cone, are respectively in meshing relation with each other so as not to impede power transmitting movement of said pulley belt in its driving connection between said driving and driven cones.

4. An infinite speed drive as claimed in claim 3 wherein two groups of gears provide said intermeshing relation and they are located on opposite sides of said pulley belt-interconnected driving and driven cones, to thereby function as position-limiting stops for said shiftable pulley belt.

5. An infinite speed drive as claimed in claim 4 wherein the gears of said two groups are of the bevel type so that there is meshing engagement therebetween even after rotation of an offset shaft discontinuing said pulley belt-positioning service of said idler cone on said offset shaft.
