Applicator for liquid coating compositions

A liquid coating composition applicator comprising;

• (a) a unitary hollow body and handle section having an applicator opening at one end and an internally threaded circular cap overlying said applicator opening, and having a container opening at the opposite end and an internally threaded circular cap and seal overlying said container opening, said section further containing;
• (1) a rigid feed tube extending from said applicator opening through said container cap and seal, the end of said tube extending from said applicator opening being oblong in shape;
• (2) a solid support member engaging the outside surface of said tube;
• (3) a rod reciprocatingly mounted in said solid support member and extending through the wall to the inside of said tube;
• (4) a flexible disc centrally mounted on said rod within said tube having a diameter substantially the same as the inside diameter of said tube;
• (5) a lever arm pivotably mounted in said section, said rod pivotably connected to the lower end of said arm;
• (6) a vertical bar extending from a spring means mounted in said handle and pivotably connected with the upper end of said lever arm;
• and
• (7) trigger means pivotably mounted in said handle connected with said bar.
• (b) a container for said liquid coating composition having an externally threaded neck removably mounted on said container cap;
• (c) a flexible feed tube connected with said rigid tube extending into said container;
• (d) a roller applicator head section comprising;
• (1) a longitudinal arched member having an oblong aperture centrally located therein;
• (2) a circular externally threaded neck portion overlying said oblong aperture and removably mounted on said applicator cap;
• said aperture communicating with said oblong end of said tubing;
• (3) a pair of triangular-faced members extending perpendicularly downward from each edge of said arched member;
• and
• (4) a hemispherical projection located on the inside surface of each triangular-faced member;
• and
• (e) a roller adapted to spread a coating composition comprising an outer surface of absorbent material, a hollow inner cylindrical support for said material and a pair of circular hub plugs fitted into each end of said cylindrical support, each hub plug having a centrally located circular recess which rotatably engages a hemispherical projection.

A device for hand pumping a liquid comprising:

• (a) a hollow body portion having a distribution opening at one end and a container opening at the opposite end;
• said portion containing;
• (1) a liquid feed tube extending from said applicator opening through said container opening;
• (2) a solid support member mounted in said portion engaging a portion of the outside surface of said tube;
• (3) a rod reciprocatingly mounted in said solid support member and extending through the wall of said tube and along the inside axis of said tube;
• (4) a flexible disc centrally mounted on said rod with in said tube having a diameter substantially the same as the inside diameter of said tube;
• and
• (b) a hollow handle portion contiguous with said body portion having pivotably mounted therein a trigger, said trigger connected by linking means with said rod for reciprocating said rod within said tube.

A device for hand-pumping a liquid coating composition comprising a unitary hollow body and handle section having a distribution opening at one end and a container opening at the opposite end, said section further containing;

• (1) a liquid feed tube extending from said distribution opening through said container opening;
• (2) a solid support member mounted in said section engaging a portion of the outside surface of said tube;
• (3) a rod reciprocatingly mounted in said solid support member and extending through the wall of said tube and along the inside axis of said tube;
• (4) a flexible disc centrally mounted on said rod within said tube having a diameter substantially the same as the inside diameter of said tube;
• (5) a lever arm pivotably mounted in said section, said rod pivotably connected to the lower end of said arm;
• (6) a vertical bar extending from a spring means mounted in said handle and pivotably connected with the upper end of said lever arm;
• and
• (7) trigger means pivotably mounted in said handle connected with said bar.
