Abstract
A method of using a masonry block mold includes the steps of loading the mold with block fill through the top of a cavity formed in the mold, drawing excess block fill from the top of the cavity, compressing the block fill within the mold with a compression head moving into the cavity from top to bottom of the cavity. The mold includes opposing sidewalls which each have at least one step formed on their respective top edge to retain additional block fill proximate thereto and assist in the formation of a flange or other structural feature on the formed masonry block.
Claims25
A method of using a masonry block mold to form masonry block having at least one flange extending therefrom, said mold having a fill-receiving cavity defined therein having an open top and bottom, said mold comprising a pair of opposed side walls connected by end walls, each of said side walls comprising a flange projecting into said fill-receiving cavity, each side wall comprising a top edge and a bottom edge, said bottom edges adapted to seat on a generally horizontal pallet, and said top edges each comprising at least one step so as to form first portions thereof which are higher than adjacent portions thereof, said method comprising the steps of:
- (a) loading said mold with block fill through said top of said cavity;
- (b) drawing excess block fill from said top of said cavity;
- (c) holding block fill proximate said first portions at a level above that proximate said adjacent portions of said top edges to form at least one flange on said block fill;
- (d) compressing said block fill within said mold with a compression head moving into said cavity from top to bottom wherein grooves are formed in said block fill by said mold side wall flanges;
- (e) stripping a formed masonry block having at least one flange extending therefrom from said mold;
- and
- (f) splitting said formed masonry block adjacent said grooves in said formed masonry block.
A method of using a masonry block mold to form masonry block having flanges extending therefrom, said mold defining a block fill-receiving cavity having an open top and bottom, said mold comprising a pair of opposed side walls connected by end walls, each of said side walls comprising a flange projecting into said fill-receiving cavity, each side wall comprising a top edge and a bottom edge, said bottom edges adapted to seat on a generally horizontal pallet and said top edges each comprising a first step forming a first end portion which is higher than an adjacent central portion, and a second step forming a second end portion which is higher than said central portion and is separated from said first end portion by said central portion said method comprising the steps of:
- (a) loading said mold with block fill through said top of said cavity;
- (b) drawing excess block fill from said top of said cavity;
- (c) holding block fill proximate said first and second end portions at a level above that proximate said central portions of said top edges to form flanges on said block fill;
- (d) compressing said block fill within said mold with a compression head moving into said cavity from top to bottom wherein grooves are formed in said block fill by said mold side wall flanges;
- (e) stripping a formed masonry block having flanges extending therefrom from said mold;
- and
- (f) splitting said formed masonry block adjacent said grooves in said formed masonry block.
A method of using a masonry block mold to form masonry block having flanges extending therefrom, said mold defining a block fill-receiving cavity having an open top and bottom, said mold comprising a pair of opposed side walls connected by end walls, each of said side walls comprising a flange projecting into said fill-receiving cavity, each side wall comprising a top edge and a bottom edge, said bottom edges adapted to seat on a generally horizontal pallet, and said top edges each comprising a first and second step, said first step forming a first end portion which is higher than an adjacent central portion, said second step forming a second end portion which is higher than said central portion and is separated from said first end portion by said central portion, said method comprising the steps of:
- a) loading said mold with block fill through said top of said cavity;
- b) drawing excess block fill from said top of said cavity;
- c) holding block fill proximate said first and second end portions at a level above that proximate said central portions of said top edges with first and second members extending across said cavity and adjoining said top edges of said opposed side walls proximate said first and second steps, respectively to form flanges on said block fill;
- d) compressing said block fill within said mold with a compression head moving into said cavity from top to bottom, said compression head having first and second steps adapted to cooperate with said first and second steps in said top edges, respectively, to provide substantially uniform compression across said top of said cavity wherein grooves are formed in said block fill by said mold side wall flanges;
- (e) stripping a formed masonry block having flanges extending therefrom from said mold;
- and
- (f) splitting said formed masonry block adjacent said grooves in said formed masonry block.
