ABSTRACT:
The mortar dispenser disclosed herein utilizes a rotating auger extending through a feed barrel at the bottom of a supply hopper to force mortar through a nozzle attached to the barrel for use in tuck pointing. Formation of a rotating plug which would obstruct flow is prevented by an auger construction in which a single helical flute divides into a pair of flutes which, in the nozzle region, extend in opposite directions from the auger axis to provide two channels. The pair of flutes are apertured to permit mortar flow between the two channels and a slender elongate spring scraper prevents mortar from sticking to the nozzle. An agitator extending into the hopper is driven by a cam rotating with the auger so as to work mortar in the hopper and cause it to flow into the auger.
