Abstract
Abstract For convenience in handling, etc., use is made of a concrete or similarly fabricated member which, although actually a single rectangular block-like member, has a surface line impression effectively simulating a selected arrangement of plural individual pavers or bricks, thereby giving the desirable impression that the construction is formed by said individual bricks, rather than by the fewer number of construction blocks. In accordance with the present invention, the line-forming means, which simulates the individual bricks, is retracted from its position impressed into the concrete mass or mixture through slots in a press-plate having wiping surfaces which removes any adhering concrete therefrom, and thus the shaping contour of said line-forming means is properly preserved for succeeding brick-simulating service. The term "brick" as used herein is intended to broadly encompass regular as well as irregular shapes, such as stones.

Claim 1
Independent Claim
305 words
An apparatus for producing a construction member of the type formed of a concrete mixture and having an imprint of lines on the surface thereof simulating an arrangement of plural individual bricks, said apparatus comprising an imprinting member consisting of a horizontally oriented panel having depending line-forming means thereon, said imprinting member being operatively arranged to be moved through a descending path projecting said depending line-forming means thereon into said surface of said concrete mixture to form said brick-simulating lines, a press-plate having a flat under-surface comprised of plural horizontally oriented cooperating units operatively mounted on vertically oriented movable supports disposed through openings in said panel of said imprinting member so as to urge said units of said press-plate member through ascending and descending movement beneath said imprinting member and above said concrete mixture along said path of movement of said imprinting member, each adjacent pair of said units being spaced apart to provide a line-like opening sized to provide wiping contact with said line-forming means during movement thereof, each said line-like opening being bounded by spaced apart walls having edges therealong effective because of said wiping contact to wipe adhering concrete from said line-forming means during the retraction of said line-forming means through a cooperating one of said line-like openings when it is moved out of imprinting contact with said concrete mixture, whereby the shaping contour of said line-forming means is maintained for subsequent imprinting service, and following which movement of said line-forming means said press-plate member is similarly adapted to be retracted clear of said concrete mixture preparatory to the unimpeded removal of said concrete mixture, and first and second pressure cylinders respectively coupled to said horizontally oriented panel with the line-forming means thereon and to said plate member to separately urge said panel and plate member through said ascending and descending movements.
Claim 2
Independent Claim
305 words
An apparatus for producing a construction member of the type formed of a concrete mixture and having an imprint of lines on the surface thereof simulating an arrangement of plural individual bricks, said apparatus comprising an imprinting member consisting of a horizontally oriented panel having depending line-forming means thereon, said imprinting member being operatively arranged to be moved through a descending path projecting said depending line-forming means thereon into said surface of said concrete mixture to form said brick-simulating lines, a press-plate having a flat under-surface comprised of plural horizontally oriented cooperating units operatively mounted on vertically oriented movable supports disposed through openings in said panel of said imprinting member so as to urge said units of said press-plate member through ascending and descending movement beneath said imprinting member and above said concrete mixture along said path of movement of said imprinting member, each adjacent pair of said units being spaced apart to provide a line-like opening sized to provide wiping contact with said line-forming means during movement thereof, each said line-like opening being bounded by spaced apart walls having edges therealong effective because of said wiping contact to wipe adhering concrete from said line-forming means during the retraction of said line-forming means through a cooperating one of said line-like openings when it is moved out of imprinting contact with said concrete mixture, whereby the shaping contour of said line-forming means is maintained for subsequent imprinting service, and following which movement of said line-forming means said press-plate member is similarly adapted to be retracted clear of said concrete mixture preparatory to the unimpeded removal of said concrete mixture, and first and second pressure cylinders respectively coupled to said horizontally oriented panel with the line-forming means thereon and to said plate member to separately urge said panel and plate member through said ascending and descending movements.
Claim 3
Dependent Claim
77 words
Apparatus as claimed in claim 1 comprising a mold box having an open top disposed beneath said horizontally oriented panel, horizontally reciprocable feed drawer means movable between a feed position above the mold box for introducing concrete mixture into the mold box and a retracted position, and projecting squeegee means on said feed drawer means for wiping said flat undersurface of said press plate member as said feed drawer means moves between said feed and retracted positions.
