Sectionalized driven rod
First Claim
1. A survey monument adapted to be driven into the ground including in combination:
- at least first and second elongated cylindrical rod sections;
means for threadedly connecting the upper end of said first rod section with the lower end of said second rod section in end-to-end relationship; and
the lower end of said first rod section terminated by a penetrating point and having at least one fluke on the periphery of said first section, said fluke spaced a predetermined distance from said point and located between the upper end of said first rod section and said point, said fluke oriented with respect to the axis of said first rod section to cause said first rod section to rotate about its axis in a direction to tighten the threaded connection of said first and second rod sections as said sections are driven into the ground.

Abstract
A survey monument of the type adapted to be driven into the ground includes at least first and second elongated cylindrical rod sections. The two sections are connected together by a threaded connector turned into threaded bores at the upper end of the first rod section and the lower end of the second rod section. The lower end of the first rod section is terminated by a conical penetrating point and a pair of flukes, formed by stamping them out of the first rod section, are located intermediate this point and the upper end of the first rod section. These flukes are oriented with respect to the axis of the rod sections to cause the sections to rotate about their axis in a direction to tighten the threaded connection of the two rod sections as the sections are driven into the ground.
