Fig. 26—Front View of Elevator Hopper, Showing Screw DrivingSprockets, Link Belt and Tighteners for Link Beltand Elevator Chain located between floor of cab and deck plate and firmly securedto the frames. Doors or slides are provided at each end of hopper forcleaning and inspection purposes. The coal is taken out of the elevator hopper and carriedto the discharge pipe by means of a main elevator chain ofspecially designed elevator buckets. Each bucket is made ofsolid one-piece malleable casting, and is supplied with hard-ened steel bushings through hinge bearing. The hinge pins are. Fig. 27—Suction of Elevator Bucket Chain made of three-quarter inch special steel, and are hardened tocorrespond with the hardened bushings used in bottom hole ofthe elevator buckets. The pins are fastened rigidly into thebosses or ears of buckets and work freely in the long bushed 130 LOCOMOTIVE APPLIANCES. bearing. This design insures great strength and minimumwear. The chain has a total strength of over 25,000 pounds,and the large hinge pins insure long life without breakage. The chain of buckets runs at about one hundred feet perminute and will elevate approximately twelve thousand poundsof coal per hour when running with the buckets full. Theusual operation is with buckets about half full. The buckets are designed to fill and empty properly at max-imum speed. The chain is not driven by the pins, but by the drivingsprocket teeth engaging the heavy boss on bottom of bucketwhich also insures long life.
