Abstract
Abstract A device for discharging measured amounts of a plural-component material, such as an adhesive, filling, sealing or putty-like substance includes an axially extending casing having a first end. The interior of the casing is divided into separate compartments each having a discharge opening at the first end. A mixing chamber is positioned at the first end of the casing for receiving the components discharged from the compartments. A slide plate is positioned between the first end of the casing and the mixing chamber and is rotatable about the axis of the casing. The slide plate has openings for passageways alignable with the discharge openings for admitting selective amounts of the components into the mixing chamber.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
225 words
Device for the measured discharge of a plural-component material such as an adhesive, sealing, filling or putty-like substance comprising a casing having a first end, said casing divided into separate compartments each extending from said first end, each said compartment arranged to hold a component of the plural-component material so that the components are maintained separate until ready to be mixed, each of said compartments having a discharge opening at said first end of said casing, a mixing chamber mounted on said first end of said casing for receiving the components from said compartments, a member interposed between said first end of said casing and said mixing chamber, said member being rotatable about an axis extending transversely of said first end, said member having passageways extending therethrough alignable with said discharge openings from said first end of said casing for conveying the components of the plural-component material from said compartments into said mixing chamber, said rotatable member is a rotational slide, a shut-off slide rotatable about the same axis as said rotational slide and located between said first end of said casing and said rotational slide, said shut off slide having bores therethrough for permitting flow between said discharge openings from said compartments into said passageways through said rotational slide so that by selectively rotating said shut-off slide flow from said compartments can be blocked.
