is shown in fig4 of the drawings the embodiment illustrated in fig4 is cross hatched to indicated metal but it will be equally understood by those skilled in the art that this embodiment of the invention is particularly well adapted for construction of plastics or virtually any other material having sufficient strength to hold the intended sign the clamp member in fig4 is generally designated at 11b and the rod is generally referred to at 10b in this embodiment of the invention the rod 10b is formed integrally with the stabilizing means 12b in that the rod 10b is somewhat triangular so that when the rod 10b is driven into the ground the width at 12b is sufficient that the stake will not rotate the clamp member 11b is formed of a rectangular stationary member 14b and a clamp bar 18b similar to the clamp bar 18 in fig1 the stationary member 14b defines holes such as the hole 30 for receiving a carriage bolt 31 as before the threaded end of the bolt 31 extends sufficiently beyond the stationary member 14b to receive the bar 18b and nuts 21b and 22b the upper surface designated at 15b includes diagonal holes 25b and 26b for receiving additional attracting means it will therefore be seen that the embodiment of the invention illustrated in fig4 includes the rectangular member 14b having the rod member 10b fixed thereto one can drive the stake into the ground by hitting the horizontal surface 15b until the stake 10b is driven into the ground sufficiently that the stabilizing means or wide portion 12b engages the ground and prevents rotation of the stake.
