The base plate and the exciter housing in the vibratory compactor of this invention comprise a one-piece casting of ductile nodular iron. The exciter housing portion of that casting, located at the front of the base plate, has coaxial holes in its opposite side walls, each large enough to receive the exciter axially. In each such hole is axially slidably received a substantially cylindrical bearing support into which a bearing for the exciter shaft is coaxially press fitted. Tab portions on each bearing support, projecting radially beyond its cylindrical surface, overlie the exterior surface of its housing side wall and provide for securement of the bearing support to that side wall by means of bolts.

Vibratory compactor having improved cast base

A trash pump having a mixed flow impeller has a housing with a rear wall through which the impeller shaft extends. A large front opening in the housing is sealingly closed by a readily detachable cover member wherein there is a port through which water enters the housing. Attached to the rear of the cover member is a volute that is received in the housing through said front opening therein and whereby water centrifuged from the impeller is guided in spiral flow to a side outlet in the housing. The rear portion of the volute, wherein there is an opening through which the impeller can pass, is adjacent to the rear wall of the housing all around the shaft. A front wall of the volute has an inlet opening in register with said port and has a rearwardly opening recess concentrically surrounding said inlet opening. An annular liner of tough elastomeric material, received in said recess, has a conical rearwardly divergent rear surface slightly spaced from front edge portions of the impeller vanes. Wear of the liner is compensated for by inserting shims in front of it in the recess.
