Claim 1
Independent Claim
167 words
A compactor for compacting solids, said compactor comprising: a. a fluid activated cylinder and a plunger; b. a bearing member on said plunger; c. a guide for said bearing member; d. said guide comprising a bottom wall and two spaced apart side walls; e. said bearing member moves between said side walls and said bottom wall; f. said side walls defining an opening at the upper part of the guide and through which opening solids may be introduced into said guide; g. two moveable spaced apart side walls juxtapositioned to said two spaced apart side walls; h. said two moveable spaced apart side walls converging toward each other upon extending from said two spaced apart side walls to define a funnel; i. a wall over which said two moveable spaced apart side walls move on one set of their edges; and, j. said two spaced apart moveable side walls being free of a cover on the other set of their edges to allow observance of their movement.
