Thisinsures buckets filling properly by always running through abody of coal. Suitable oiling places will be found at bearing points ofmoving parts on hopper, all of which are easily accessiblethrough trap door in locomotive cab floor—the hopper being LOCOMOTIVE APPLIANCES. 129. 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
