Abstract:
A manually operable viscous liquid screed, comprising:a body adapted to engage an application surface;said body having a front portion, a rear portion, a front surface, a rear surface, a top surface, a substantially planar bottom surface, a right side and a left side;said right side and said left side defining a first transverse width of said body;said body front and rear portions being engageable by hand at said front and rear surfaces respectively;said body having an opening extending from said top surface through said body to said substantially planar bottom surface;said opening having a second transverse width which is less than said first transverse width;whereby when said body contacts said application surface, said opening and said application surface define a reservoir adapted to receive a viscous fluid;a first recess in the rear portion of said body extending upwardly from said planar bottom surface and adjacent to said opening;said first recess having a first height;said first recess having a third transverse width substantially equal to said second transverse width; said first recess being coextensive with said opening;said first recess having a first left substantially vertical side and a first right substantially vertical side;and a second recess in the rear portion of said body extending upwardly from said planar bottom surface;said second recess being to the rear of and adjacent to said first recess and extending to said rear surface of said body;said second recess having a second height greater than said first height;said second recess having a fourth transverse width greater than said third transverse width and less than said first transverse width;said second recess having a second left substantially vertical side and a second right substantially vertical side; andsaid second recess, said opening and said first recess defining a rib between said opening and said second recess, said rib having a rib bottom surface;whereby when said body contacts said application surface, said first recess defines a substantially rectangular first release orifice;and whereby when said body contacts said application surface, said second recess defines a second release orifice; and whereby when said reservoir contains said viscous fluid and said body is propelled across said application surface, said viscous liquid is forced by gravity through said first and second release orifices to deposit a layer of said viscous liquid on said application surface, the height of said layer of viscous liquid being defined by said rib bottom surface, and the width of said layer of viscous liquid being defined by said first left and right substantially vertical sides.
