3 Claims. (Cl. 85v--2`.4‘)-
My invention relates to anchoring devices of

opening II at the junction of the end Illa and
tapered wall portion Iilb is concaved to serve
made of concrete, brick or the like.
One of the objects of my invention is to proi-à

member I5 is provided with an internally thread-Y

In Figs. 4 and 5 I have shown a modified form
