In order that the entire area of the grate may be uniformlyeffective, the Hulson Grate Company, Keokuk, Iowa, hasdesigned a locomotive grate in wliich the drop grate is re-placed by three finger bars in a frame which may be swungupward about a shaft journaled at the front end of the grate. Side View of the Grate Showing the Operating Connections frames. Standard Hulson finger bars are used in the liftingframe and they are shaken as a part of the front section ofthe grate. The construction of the device is simple and will readilybe understood by reference to the illustrations. It will beseen that the side and center frames are recessed at the frontends, the length of the recess being sufficient to take in thecast steel lifting frames of rectangular cross-section with trunnion bearings for the three standard finger bars. Squareholes are cored tlirough the ends of the lifting frames, whichare reinforced with hubs to provide ample strength, and theframes are mounted on a 2-in. square wrought iron staff, with the lifting frames and a cast steel liftingarm mounted on it, is placed in the stationary grate frames,one end being slipped into a circular hole cored in the sideframe and the other dropped into a slot in the center assembled the slot in the cente
