Title: System of construction components for the production of roller assemblies
Claims: What is claimed is: 1. A roller assembly for a roller train comprising a fixed cylindrical axle; a roller pipe having cylindrical inner and outer surfaces; first and second end members each having bearing means therein, said members being slidable onto said axle for rotation thereon, each of said end members having a hub extending into and frictionally engaging the interior surface of said pipe, and a flange having a larger outer diameter than said hub, said flange forming a shoulder abutting an end of said pipe; pulley means integrally formed on said first one of said end members for cooperating with drive means to rotate said roller assembly about said axle; a plurality of hollow frustoconical members slidable onto said pipe in end-to-end relationship surrounding said pipe and in coaxial relationship therewith, the outer surfaces of said frustoconical members making equal angles with the axes thereof, the smaller end of each said member being of equal diameter with the larger end of the next adjacent one of said members to form a continuous frustoconical outer surface along the length of said roller assembly; and an annular spacer member between the larger end of the largest one of said frustoconical members and said pipe to maintain said larger end in coaxial relationship with said pipe. said spacer member having means defining a shoulder abutting the larger end of said largest member. 2. A roller assembly according to claim 1 wherein each of said frustoconical members includes means at the smaller end thereof defining a collar having a central bore substantially equal in inner diameter to the outer diameter of said pipe and an outer surface portion of reduced diameter, said reduced diameter being substantially identical to the inner diameter of the larger end of the next adjacent frustoconical member, whereby said frustoconical members are mating and frictionally engaged with each other and with said pipe. 3. A system of components interchangeably usable to assemble roller assemblies for a roller train on a fixed cylindrical axle, comprising a roller pipe having cylindrical inner and outer surfaces; first and second end members each having bearing means therein and being slidable onto said axle for rotation theron, each of said end members having a hub slidable into said pipe for frictionally engaging the interior surface thereof, and a flange having a larger outer diameter than said hub, said flange forming a shoulder abutting an end of said pipe; pulley means integrally formed on said first one of said end members for cooperating with drive means to rotate said roller assembly about said axle; a plurality of hollow frustoconical members slidable onto said pipe in end-to-end relationship surrounding said pipe and in coaxial relationship therewith, the outer surfaces of said frustoconical members making equal angles with the axes thereof, the smaller end of each said member being of equal diameter with the larger end of the next adjacent one of said members to form a continuous frustoconical outer surface along the length of said roller assembly; and an annular spacer member between the larger end of the largest one of said frustoconical members and said pipe to maintain said larger end in coaxial relationship with said pipe, said spacer member having means defining a shoulder abutting the larger end of said largest member.
