We refer to the two-belt con-veyor system designed by the Ridgway Belt Conveying New York, in which an interior troughing and supporting beltruns over its individual head and tail pulleys, having separate take-ups, and is entirely independent of the conveying belt proper. The conveying belt is threaded over its head and tail pulleys in the usualmanner, and has its separate take-up, so that the two belts, althoughmoving together in the same direction at the same speed, are entirelyseparate and distinct. This enables the conveying belt to be liftedoff the supporting belt and out of the troughing blocks and passedthrough either a stationary dumper or a moving tripper. The conveying belt has no work put upon it other than that re-quired to drive the lower carriers and its own head and tail pulleys,all the carriers on the upper line, which comprise two-thirds ofthe total number used, being revolved by the inner supporting tie. I.— USED I.\ TWO-BELT CONVEYOR. The strains, therefore, are divided, the belt revolving two-thirdsof the moving parts not being subject to the wear and tear of carry-ing the load, and the belt carrying the load being relieved of thestrains and wear and tear of revolving the greater part of the movingparts of the machine. This produces a divided labor in wear andtear which enables both belts combined only to represent in strengthwhat would be required of one belt in any one-belt system. The interior belt is driven by a roller or block chain sprocket drivefrom the main driving shaft, and with the two belts in tension justsufficient to prevent slip on their driving pulleys; both belts moveat exactly the same speed in the same direction, and there is no rub
