Apparatus for unstacking flat steel material which is transported stacked on a rake cooling bed

Claim 1

Apparatus for unstacking stacks of flat steel bars which have been moved over a rake cooling bed having stationary and movable rakes, said stacks being positioned with the flat sides of said bars parallel to the descending flanks of said rake cooling bed in the direction of movement thereof with the side edges of said bars on the ascending flanks, characterized by a. a plurality of sliders positioned between said stationary and movable rakes transverse of said direction of movement, adjacent the last cogs of said stationary rake; b. said sliders being mounted separately from said stationary and movable rakes; c. said sliders having bearing surfaces for said stacks substantially parallel to the descending flanks of said last cogs; d. movement means connected to each said slider; e. said movement means positioned to move said plurality of sliders from a first position below said stationary rake to a second position above said stationary rake and vice versa; and f. said movement means positioned to move said plurality of sliders parallel to the ascending flanks of said last cogs; g. whereby upward movement of said slider causes upward movement of said stacks on the ascending flanks of said last cogs and the spaced delivery of each bar of said stacks down the descending flanks of said last cogs; and h. said movement means comprises
