Levelled cement spreader for laying tiles
First Claim
1. An apparatus for producing onto a floor surface, a level surface of a cementitious material comprising:
- a base adapted for displacement on the floor surface, and a container surmounting said base and resting thereon, and adapted to receive the cementitious material,said container having a front wall, a rear wall and a bottom opening, said rear wall including a downward extension which is pivotally mounted on said rear wall,means for causing pivoting of said downward extension to thereby enlarge or reduce the size of the bottom opening of said container and vary the amount of cementitious material discharged from said container into said base depending on required amounts thereof,said base having an opening which trails the discharged cementitious material from said container on the floor surface when said apparatus is operatively displaced, said base opening being defined by a front wall of said base which is vertically spaced from the floor surface,a gate movably mounted on said base front wall to be vertically displaced for selectively enlarging or reducing said opening,sensor means detecting irregularities in said floor surface, andcontrol means responsive to said sensor means enabling to move said gate for spreading the cementitious material passing therethrough to produce said level surface.

Abstract
The present invention relates to an apparatus for applying cementitious material onto a floor surface while screeding it and producing varying depths of ridged impressions in a longitudinal direction within the cementitious material, from deep ridges to flat surfaced material, all formed with a levelled surface, adapted to receive tile components and other flooring products. The apparatus includes a base adapted for displacement on the floor surface and provided with a container to receive the cementitious material. The container is adapted to discharge a required amount of cementitious material on the floor surface. The base defines an opening which screeds the material onto the floor surface and trails the discharged cementitious material from the container on the floor surface when the apparatus is operatively displaced. A gate is moveably mounted to be vertically displaced for selectively reducing the opening and for evenly spreading the cementitious material passing therethrough. A plurality of spring loaded fingers mounted onto the front of the base are biased to abut onto the floor surface and are adapted to scrapingly remove levelled discharged cementitious material in operation of the apparatus for forming spaced apart channels substantially free of cementitious material or varying in depth up to a flat surface.
