Abstract
An applicator head apparatus disposable on the end of a handle, including an applicator valve and a wiper head. The applicator valve further including a socket mounted on the wiper head and a coupling assembly with one end connected to the handle and the other end having a cylinder member rotatably mounted in the socket, the applicator valve having a first position preventing flow and a second position permitting flow.
Claims11
An applicator head apparatus disposable on the end of a handle, comprising:
- an applicator valve;
- a wiper head;
- the applicator valve further including a socket mounted on the wiper head and a coupling assembly with one end connectable to the handle and the other end having a cylinder member rotatably mounted in the socket, the applicator valve having a first position preventing flow and a second position permitting flow;
- and
- the wiper head including a fluid chamber enclosed therein, said fluid chamber is defined by an inner structure of the wiper head for directing material flow, said inner structure is arranged and configured to allow material to be evenly spread on a surface;
- wherein the wiper head is defined by an upper plate and a lower plate enclosing the fluid chamber and the inner structure is formed on to lower plate.
An apparatus for spreading materials on a surface, comprising:
- a pump system connected with a conduit, the pump system capable of pumping materials through the conduit;
- an applicator head connected to a handle, the handle being connected to the conduit;
- the applicator head including an applicator valve and a wiper head and;
- a flow path is defined from the pump system to the applicator head;
- the applicator valve is disposed in the applicator head, the applicator valve being normally biased into a closed position, the applicator valve being opened upon pivotal movement of the handle relative to the applicator head so as to allow material to flow through the flow path and
- the wiper head including a fluid chamber enclosed therein, said fluid chamber is defined by an inner structure of the wiper head for directing material flow, said inner structure is arranged and configured to allow material to be evenly spread on a surface;
- wherein the wiper head is defined by an upper plate and a lower plate enclosing the fluid chamber and the inner structure is formed on the lower plate.
A method for spreading materials on a surface using a pump system connected by a conduit to a handle which in turn is attached to an applicator head;
- comprising the steps of:
- activating the pump system to pump the materials;
- positioning the applicator head on a surface on which materials are to be spread;
- causing flow of materials through the applicator head to the surface upon pivotal movement of the handle relative to the applicator head;
- and
- directing the flow of materials through the applicator head so that the materials are evenly spread on the surface;
- whereby the materials are evenly spread by directing the flow of materials through a wiper head of the applicator head, the wiper head having an inner structure defined by an upper plate and a lower plate enclosing a fluid chamber and the inner structure is formed on the lower plate.
