Drywall finishing tool

A plasterer's tool for applying plaster or like substances to a wall surface adjacent to an outside wall corner edge comprising:

• a housing for receiving and holding a quantity of plaster, said housing having spaced apart end walls, a top wall, and opposed front and rear walls, said front wall having an elongated outlet opening therethrough adjacent to the top wall, the rear wall including a portion hingedly attached adjacent one edge to the end walls and movable from a position spaced from said front wall to a position adjacent to said rear wall;
• and
• guide means mounted on the housing for movement along the elongated opening to block a pre-determined portion of one end thereof, means for attaching the guide means to the housing in a desired position, said guide means having an outwardly extending portion located in alignment with the desired blocked end of the opening for engaging a wall corner edge during movement of the tool therealong to maintain the one end of the opening aligned with the wall corner edge during tool movement preventing plaster from exiting the opening beyond the corner edge.

In a tool for laying plaster along a wall surface adjacent to an outside corner edge, the tool having a housing with an elongated outlet opening through which plaster is dispensed during operation of the tool, the improvement comprising guide means for mounting on the tool for movement along the elongated opening to block a predetermined portion of one end of the outlet opening including means thereon aligned with the blocked end of the opening for engaging a wall corner edge to guide the tool when laying plaster along a surface adjacent to the outside corner edge, said guide means including a guide assembly for mounting on the housing in position to close said predetermined portion of one end of the outlet opening and means for locking the guide assembly in a desired position along the outlet opening to establish a desired position for the one end of the opening, said guide assembly having an outwardly extending portion located in alignment with the blocked end of the opening for engaging an outside corner edge during movement of the tool therealong to maintain the blocked end of the opening aligned with the wall corner edge during tool movement preventing plaster from exiting the opening beyond the corner edge.

A plasterer's tool for applying a plaster substance to a wall surface adjacent to an outside wall corner edge defined by angularly related wall surfaces comprising a housing having spaced end walls, a wall with an elongated opening therein adjacent one side edge, an opposite wall including a wall portion pivotally attached to and extending between the end walls, and a closure wall extending between the wall with the opening therein and the opposite wall to close the space therebetween, operator means connected to the pivotal wall portion for applying pressure thereto during plastering to force plaster out through the elongated opening, and guide means mounted on the housing for movement along the elongated opening to block a pre-determined portion of one end thereof and prevent plaster from exiting the opening beyond the corner edge, said guide means including means forming an outwardly extending portion for making sliding contact with the outside wall corner edge and guide movement of the tool when applying plaster to the wall surface adjacent thereto.
