Novel anode fitting

Claim 2

An anode fitting for use in the prevention of the corrosion of a metallic structure containing a corrosive liquid which comprises: A. a non-metallic plug member comprising a threaded outer portion adapted to be threadedly received within an opening in the structure and a hollow cylindrical inner portion; B. a cylindrical anode telescoped to said inner portion and secured thereto; and C. means for electrically connecting said anode and said structure which comprises several metal pins in perpendicular relation to the long axis of said anode and partially embedded therein and extending beyond said plug member, and a metallic cup-shaped washer placed over the threaded portion of said member and adapted to be compressed between said pins and the exterior wall of said structure.

Claim 3

The fitting of claim 1 wherein said plug member comprises a material selected from the group consisting of thermoplastic resins and thermosetting resins.

Claim 4

The fitting of claim 1 wherein the anode possesses a coaxial structure and comprises an outer anode body and an inner core element.

Claim 5

The fitting of claim 1 wherein two of said metal pins are employed in said connecting means.

Claim 6

An anode fitting for use in the prevention of the corrosion of a metallic structure containing a corrosive liquid which comprises: A. a non-metallic plug member comprising a threaded outer portion adapted to be threadedly received within an opening in the structure and a hollow cylindrical inner portion adapted to provide a fluid passageway for said structure; B. means located on said plug member for attachment to a water line; C. a cylindrical anode telescoped into the plug member and secured thereto; and D. means for electrically connecting said anode and said structure which comprises several metal pins in perpendicular relation to the long axis of said anode and partially embedded therein and extending beyond said plug member, and a metallic cup-shaped washer placed over the threaded portion of said plug member which houses said anode, and adapted to be compressed between said pins and the exterior wall of said structure.

Claim 7

An anode fitting for use in the prevention of the corrosion of a metallic structure containing a corrosive liquid which comprises: A. a non-metallic plug member comprising a threaded outer portion adapted to be threadedly received within an opening in the structure and a hollow cylindrical inner portion adapted to provide a fluid passageway for said structure; B. means located on said plug member for attachment to a water line; C. a cylindrical anode telescoped into the plug member and secured thereto; and D. means for electrically connecting said anode and said structure which comprises several metal pins in perpendicular relation to the long axis of said anode and partially embedded therein and extending beyond said plug member, and a metallic cup-shaped washer placed over the threaded portion of said plug member which houses said anode, and adapted to be compressed between said pins and the exterior wall of said structure.

Claim 8

The fitting of claim 5 wherein said attachment means comprises a tubular extension of said plug member leading away from said anode and possessing an outer connecting surface and an inner fluid passageway.

Claim 9

The fitting of claim 6 wherein threads are defined on said outer connecting surface.

Claim 10

The fitting of claim 6 wherein said fluid passageway comprises: a first fluid passageway in said tubular extension; and a plurality of smaller passageways located in said plug member radially displaced in relation to said anode and parallel thereto, extendinG past said anode to communicate with said first fluid passageway.

Claim 11

The fitting of claim 5 wherein said plug member comprises a material selected from the group consisting of thermoplastic resins and thermosetting resins.

Claim 12

The fitting of claim 5 wherein the anode possesses a coaxial structure and comprises an outer anode body and an inner core element.

Claim 13

The fitting of claim 5 wherein two of said metal pins are employed in said connecting means.

Claim 14

An anode fitting for use in the prevention of the corrosion of a metallic structure containing a corrosive liquid which comprises: A. a non-metallic plug member comprising a threaded outer portion adapted to be threadedly received within an opening in the structure and a hollow cylindrical inner portion; B. a cylindrical anode telescoped into said inner portion and secured thereto which comprises an outer anode body and an inner core element, said core element axially extended beyond the anode body and through said plug member; and C. means for electrically connecting said anode and said structure which comprises a wire attached at one end to a clamp secured to the axial extension of said core element, said wire attached at the opposite end thereof to a metallic cup-shaped washer which is placed over said threaded outer portion and adapted to be compressed between said plug member and the exterior wall of said structure.

Claim 15

An anode fitting for use in the prevention of the corrosion of a metallic structure containing a corrosive liquid which comprises: A. a non-metallic plug member comprising a threaded outer portion adapted to be threadedly received within an opening in the structure and a hollow cylindrical inner portion; B. a cylindrical anode telescoped into said inner portion and secured thereto which comprises an outer anode body and an inner core element, said core element axially extended beyond the anode body and through said plug member; and C. means for electrically connecting said anode and said structure which comprises a wire attached at one end to a clamp secured to the axial extension of said core element, said wire attached at the opposite end thereof to a metallic cup-shaped washer which is placed over said threaded outer portion and adapted to be compressed between said plug member and the exterior wall of said structure.

Claim 16

The fitting of claim 12 wherein said plug member comprises a material selected from the group consisting of thermoplastic resins and thermosetting resins.
