Liquid applicator with scraper and method of use

A device for applying and removing a hardenable liquid to a surface comprising in combination:

• a first portion having a container for said liquid, an applicator surface carried on an upper portion of said first portion for applying said liquid to said surface, and a means for supplying liquid from said container to applicator surface;
• a second portion having a receptacle for removeably receiving said upper portion of said first portion and covering said applicator surface, said second portion carrying a scraper blade on an upper portion thereof for removing said liquid from said surface after said liquid has hardened thereon;
• and
• a third portion for removeably receiving said upper portion of said second portion and covering said scraper blade.

A device for applying and removing a hardenable liquid to a surface comprising in combination:

• a first unit consisting of a liquid container, an applicator carrying an exposed sponge, a valve for supplying said liquid from said liquid container to said sponge upon the application of external pressure to said sponge, and a mounting means in which said sponge and said valve are supported;
• a second unit having a lower hollow portion for removeably receiving and covering said exposed sponge, said lower portion being press fit with said mounting means, and having a blade carried in a blade mount for removing said liquid from said surface after said liquid has hardened thereon;
• and
• a cap for removeably receiving and covering said blade and said blade mount, said cap being press fit on said blade mount.

A device for applying a hardenable liquid to a glass windowpane surrounded by a frame to be coated with a flowable agent, said device comprising:

• an applicator portion having a container for said liquid, an applicator mount having sidewalls adapted for sliding along and against said frame, an applicator surface carried in said applicator mount and surrounded by a rim of said applicator mount such that said applicator surface is in continuous contact with said windowpane at a distance from said frame as one of said sidewalls of said applicator portion slides along and against said frame for applying a thin film of said liquid to said pane leaving a gap of exposed glass between said film and said frame, said frame, said gap and a portion of said film being subsequently covered with said flowable agent;
• and
• a scraper portion having a hollow interior for removeably receiving and covering said applicator surface, said scraper portion resting on said rim surrounding said applicator surface forming a substantially continuous external surface with said container, a blade mount having sidewalls adapted for sliding along and against said frame, and a blade carried in said blade mount surrounded by a rim of said blade mount such that said blade is in substantially continuous contact with said pane as one of said sidewalls of said blade mount slides along and against said frame for scraping said film together with any of said agent thereon from said pane without contact with the agent coating said gap.

A method for masking selected portions of a glass pane mounted in a frame to be covered with a flowable agent comprising the steps of:

• applying a hardenable liquid over a portion of said pane using an applicator having a container for said hardenable liquid and an applicator surface offset from an edge of said container by running a side of said container along said frame such that a gap of exposed glass is left between said frame and the hardenable liquid applied to said pane;
• permitting said hardenable liquid to harden on said pane thereby forming a protective film over said portion of said pane;
• coating said frame with said flowable agent such that said coating of flowable agent extends over said gap and onto said film;
• and
• removing said film and any agent thereon from said pane thereby leaving a border of said agent adjacent said frame on said pane for sealing said pane in said frame.

A method for masking selected portions of a glass pane mounted in a frame to be covered with a flowable agent, said method using an applicator having a container with sidewalls and an applicator surface and a scraper blade respectively offset from said sidewalls by substantially the same distance, said method comprising the steps of:

• running one of said sidewalls of said container along an edge of said frame with said applicator surface in contact with said pane for applying a film of hardenable liquid over a portion of said pane spaced from said frame by a gap of exposed glass defined by said offset;
• permitting said hardenable liquid to harden on said pane thereby forming a protective film over said portion of said pane;
• coating said frame with said flowable agent such that said coating extends over said gap and onto said hardened film;
• and
• running a sidewall of said container again along an edge of said frame with said blade in contact with said pane for removing said film and any flowable agent thereon from said pane and leaving a border of flowable agent on said pane defined by said offset for sealing said pane in said frame.
