US Patent 7614813 Grout dispenser

A grout dispenser which dispenses a grout mixture from a container through a tracking square-toothed-shaped nipple having an off-on valve and extrudes the mixture into spaces between previously-set tiles. A utility stand, a grout float device and a tracking wheel to maintain a straight line are included. In use, the strip glides over the edges of the installed tiles on a predetermined width, spaces or tracks. By gliding over the uncured grout, mortar, the float gives the spaces or tracks a concave appearance.
