A cathodic protection system for a burial casket comprises a sacrificial anode rod, nylon sleeves encircling the rod and metal straps positively positioned relative the sleeves and welded to the casket bottom. One of the sleeves encircles the resistor of the system. The lead of the resistor connected between the casket and strap is carried in a slot in the one sleeve. The strap includes a welding dimple and a dog-eared corner which traps the lead between the casket bottom and the strap during welding of the strap to the bottom.

This invention relates generally to caskets, and more particularly to improvements in cathodic protection for metal, and in particular steel, caskets.
Metal caskets, and in particular steel caskets, upon being buried are subject to the effects of ground water. Depending on the location of burial, the ground water may contain salt or other minerals. Exposure to such ground water provides a corrosive potential which becomes actual upon the deterioration of the casket finish and the ultimate exposure of the bare metal to the elements.
Caskets have been provided with protection against corrosion by electrically connecting a sacrificial anode to the casket, whereby the casket becomes the cathode of an electrolytic cell in the presence of ground water. This sacrificial anode may be made of zinc, aluminum, magnesium or any other metal of higher electromotive potential than that of the cathode (casket).
FIG. 1 is a side elevational view of a burial casket employing the principles of the present invention;
FIG. 2 is a bottom view taken along line 2--2 of FIG. 1;
FIG. 3 is the encircled area 3--3 of FIG. 2, greatly enlarged;
Referring first to FIG. 1, a metal, for example mild steel or stainless steel, casket 2 includes a body portion 4 and a top portion 6 sealable to the body portion 4. Body portion 4 includes a bottom 8.
Referring now to FIGS. 2-11, and initially to FIGS. 2-5, bottom 8 includes an elongated semi-circular recess or groove 10. Near either end of the groove 10, a transverse groove or recess 12 is located. In the center of the groove 10, a third groove or recess 14 is located. Recesses 12 and 14 are not as deep as the recess 10.
Within the recess 10, there is located a sacrificial anode 16 in the form of an elongated rod or bar. Anode rod 16 is semi-circular in cross section and fits within the semi-circular recess 10 essentially flush with the bottom 8 of the casket 2.
