Stone Mortar Mixer Line Receives Canadian Patent

Stone Construction Equipment Inc. has received a patent from the Canadian Patent Authority for the removable seal and bearing housing on the Stone Champion line of Mortar Mixers. The housing attaches with three bolts and contains Stone’s patented quadruple seal and bearing configuration. The removable housing makes servicing much easier and quicker, thereby reducing downtime and maximizing uptime.

The patent includes the housing, which facilitates servicing of the seals and bearing; an opening in the housing which allows contamination to drop out before reaching the bearing; the unique built-in puller flange for easy removal of the bearing; and the method of attaching the housing to the end walls of the mixer.

The removable housing is standard on all sizes of both steel and poly drum Stone Mortar Mixers, and it provides quick and easy servicing or replacement of the seals or the bearing without requiring the paddle shaft to be cut.

The removable housing had already received a United States patent. The housing is only one of numerous Canadian and U.S. patents held by Stone for its Concrete, Mortar and Silo Mixer lines.
