Definitions

  • this conveyor system comprises a lower pair of substantially endless belts 300 and an upper pair of belts 301.
  • each of the belts is of roller chain with the individual links 302 (FIGS. 9 and 10) being formed with bent lug attachments 303.
  • Rubber blocks 304 having alternately notched or saw-tooth" ends are adhered to plates 305 that are secured as by bolts 306 to the bent lugs 303 of the chain links.
  • the pairs of roller chain belts 300 and 301 are entrained about suitably mounted sprockets to traverse substantially rectangular paths of movement.
  • the shaft 334 is joumaled in bearings 339 mounted on pedestals 211 and 212 whilele the shaft 335 is joumaled in tensioning bearing members 340 on the pedestals 201 and 202 (FIG. 2).
  • the shaft 336 is joumaled in bearings 342 mounted on brackets 343 supported on the upper ends of the pedestals 201 and 202.
  • the shaft 337 is joumaled in bearings 345 on brackets 346 at the upper ends of pedestals 211 and 212.
  • the carriage 400 of the edge treating unit 400 is adapted to support the associated frame member 415 in a substantially vertical position upon securement of the bracket 420c to the bracket 416 by bolts 422. This will locate the associated grinding belt 435 so that the working run thereof will act upon the vertical surface of the edge E of the sheet.
  • this carriage 400 by sleeve bearings 405 is supported on the bars 406 that are mounted by blocks 407 on the beams 232-233 between the transverse beams 223 and 231.
  • FIG. 15 This manner of action is illustrated diagrammatically in FIG. 15 wherein it will be noted that application of pressure via the valve 510 is controlled to a solenoid-type self-reversing supply valve 530 connected to a source of pressure by pipe 531. Normally, pressure is directed from valve 530 by pipe 532 through the valve 510 by a pipe 533 connecting to the rod end of a cylinder 410. This will hold the carriage 400 in the idle or rearward position such as is indicated by the positions of the units 40a, 40b and 400 in FIGS. 2, 4 and 6, respectively.
  • apparatus for edge treating glass sheets which includes means for moving said sheets along a definite path, a tool having an abrasive surface mounted for movement toward and away from said path, and means for driving said tool to move said abrasive surface relative to said path; the improvement which comprises monitoring means operable when one of said glass sheets reaches a predetermined position in said path to move said tool under pressure toward said path and for reducing said pressure when said tool is in working engagement with an edge of one of said sheets, said monitoring means including a follower adapted for moving engagement with said sheet edge.
  • said means for moving said tool comprises a fluid operated device
  • said monitoring means includes a follower engageable and adapted for moving contact with said sheet edge
  • said pressure reducing and varying means comprise a valve operatively connected to said follower for controlling the supply of fluid to said device.
