Abstract

Abstract A device for applying a floor covering in the liquid state made up of a tank suitable to be carried on the shoulders of an operator. A hose is connected to the bottom of the tank. A hollow wand or pipe is connected to the hose and a dispenser head is connected to the wand. The wand extends upward from the dispenser head at an angle of approximately 30*. The liquid can flow from the tank to the head when a valve is opened. The dispenser head in its preferred form is approximately 12-24 inches long and 2 inches wide, and 1 inch deep. The dispenser head is generally rectangular in cross section and has three parallel grooves extending across its bottom. The grooves are V-shaped and each has a row of holes at its apex extending from one end of the dispensing head to the other. The wand is connected to one end wall of the dispensing head. The holes in each row are staggered from the holes in the other so that streams of liquid from the holes are evenly distributed over the floor and a smooth coating results. The method of applying liquid flooring by applying parallel streams is also part of the invention.
