  • Patent number: 4615156
    Abstract: A ground anchor for channel posts has an angle iron leg driven into the ground and an upright fin plate or strip secured to the upper end thereof to stabilize the leg against tilting. The channel post straddles the angle iron leg receiving the apex of the leg in the channel thereof and is deformed to spread its legs apart into tight gripping relation with the angle iron. The spreading apart of the legs may be effected by drawbolts which fixedly connect the channel post with the angle iron leg or by a tool applied to the post adjacent the leg permitting the post to enter a socket on the leg formed by the fin plate or strip whereupon releasing of the tool permits the spread apart post legs to spring back toward their free state position thereby bottoming the base of the post in the socket. The spread apart legs of the post tightly grip the angle iron leg. The post may be removed from the angle by releasing the drawbolts or by again applying a spreading tool to free the post from the socket.

The channel post straddles the angle iron with its side legs bottomed on the sides of the angle iron and a compression member bottomed on the strip forces the channel post against the angle iron to spread the legs of the post into tight gripping relation with the angle iron locking the post in the socket. The socket is open-ended and the post can slide over the angle iron leg to any desired depth so that a sign mounted on top of the post can be positioned at a selected height above the ground. The angle iron is driven into the ground to a depth sufficient to bury the shroud strip so that the post is the only portion of the assembly projecting above the ground.

  • Patent number: 4327534
    Abstract: A method and apparatus for permanently extending the height of an upright pole set in the ground uses pole reinforcers which are driven in the ground alongside and complemental to the pole. Extensible power devices mounted on ground-engaging supports use gripping heads mounted adjacent the upper end of the device, in such manner that actuation of the devices holds the heads in biting engagement with the pole. As the devices are extended, the heads pull the pole from the ground and through the predetermined channel formed by the pole reinforcers. Once the pole is extended to the desired elevation, the pole reinforcers are permanently secured to the pole to provide stability at the new height. The present invention is useful in moving the pole through extended displacements in a single stroke of the hydraulic cylinders of the devices, obviating the necessity for successive attachment and detachment of the apparatus during raising of the pole.
