Definitions

  • Another ob]ect of the invention is to provide a novel and improved conveyor roll for Aa high temperature heat-treating furnace of the character indicated.
  • Figure 1 is a transverse sectional view
  • Fig. 2 is a detail sectional plan view taken substantially on the line 2-2 of Fig. 1;
  • Fig; 3 is a detail end view of the shaft of one of the rolls and its supportin bearing.
  • the furnace illustrated 1n the rawings is provided with a furnace chamber having side walls 2, a top wall 4, and a bottom wall 6, an conveyor ro ls extending transversely of the furnace chamber, each roll comprising a shaft 8 and Amaterial conveying disks 10 s ecured thereon.
  • the disks 10 of the'several rolls are arranged in staggered relation so as to permit each disk to extend into the spaces between adjacent diskseof adjacent rolls with the periphery of the disk positioned in close l5 proximity to the shafts of the-adjacent rolls.
  • the ends of the shafts are supported on roller bearings '12 that are mounted in cradles 14 set into or secured in recesses 16 in the inner sides of the side walls of the furnace chamber, the
  • this coupling consists of a collar or sleeve which is 'telescoped over the adjacent 65 ends of the associated drive shaft and roll shaft and is loosely connected therewith by bolts 26 arranged transversely of each other, and extended through apertures in the Acoupling sleeve and the ends of the shafts.
  • conveyor roll' shafts may be made hollow, and saidshafts, couplings, conveyor disks and'roller bearings may be made of a suitable heat-resisting alloy.
  • the conveyor rolls are mounted in such 'a manner as to allow for expansion and contraction, vand close fitting of parts is unnec-v essa-ry.
  • a. heat-treating furnace of the class described the combination of a furnace chamber having side walls, conveyor rolls extending between the side walls, bearings for the ends of said rolls mounted adjacent the inner sides of the side Walls, one of the side walls having an opening in alinement with each roll, andv means for driving said roll comprising a drive shaft, a bearing for the drive shaft arranged outside of the furnace, and coupling ⁇ means connecting one end of each roll with its drive shaft through the opening associated with the roll, said conveyor rolls and the bearings therefor being located entirely Within the furnace chamber.
  • a heat-treating' furnace of the class described. the combination of a furnace chamber having-v side Walls, a. conveyor roll extending between the side Walls, bearings for the ends of said roll set into said side Walls, one of said side Walls having?,y an open ⁇ y ing in alinement with said roll, a drive shaft for the roll, and a exible coupling 'connectings, ⁇ one end of the drive shaft with one end of the roll ⁇ said end of the drive shaft eny tending into lsaid opening, andthe ends of said roll being ⁇ spaced inwardly from the outer sides of said side Walls, said conveyor rolls and the bearings therefor being located entirely Within the furnace chamber.
