ABSTRACT:
A cartridge type dispensing gun comprises a housing and a barrel in which is mounted a cartridge containing a supply of viscous material. A plunger is driven to extend from the housing into the barrel for pushing a piston at the rear end of the cartridge to force the contents thereof out of a spout formed at the front end of the cartridge. The spout is in use to be cut off at an angle of about 45.degree. to leave an angled edge which is utilized as a spatula when applying a bead of viscous material to a surface being treated. A joint assembly connects the barrel to the housing in such a manner that the barrel together with the cartridge received therein is rotatable about its axis with respect to the latter and is locked in one of a plurality of angularly displaced positions about that axis, whereby the angled edge of the spout can be adjusted to change its angular orientation so as to be effectively utilized as a spatula depending upon differing requirements of the surface to be treated while allowing the housing to be held at a comfortable position.
