Apparatus for mixing solid and liquid constituents of mortar or the like

Apparatus for mixing flowable solid and liquid constituents, such as cement and water, comprising a housing including a first section having inlet means for admission of the solid constituent, an intermediate section communicating with, and having a cross-sectional area smaller than that of, said first section, and a mixing chamber communicating with said intermediate section;

• means for admitting the liquid constituent into the interior of said mixing chamber;
• and means for conveying the solid constituent from said first section into said mixing chamber via said intermediate section, including a rotary feed screw journalled in said housing and including a helical thread extending through the interior of said sections and snugly surrounded by said intermediate section.

Apparatus for mixing flowable solid and liquid constituents, such as cement and water, comprising a housing including a first section having inlet means for admission of the solid constituent, an intermediate section communicating with said first section, and a mixing chamber communicating with said intermediate section and having an outlet opening for the mixture of solid and liquid constituents and a cover movable relative to said outlet opening between first and second positions in which said cover respectively overlies and exposes said outlet opening;

• means for admitting the liquid constituent into the interior of said mixing chamber;
• and means for conveying the solid constituent from said first section into said mixing chamber via said intermediate section, including a rotary feed screw journalled in said housing and including a helical thread extending through the interior of said sections.
