Method of installing a screw-type anchor

The method of securely placing a screw-type anchor in the earth without unduly disturbing the surrounding soil, including the step of enveloping the anchor's shank in a special tubular mandrel. The mandrel has a helical flight near its bottom end, with a pitch that is substantially the same as the anchor's flight, such that the mandrel's flight constitutes an effective extension of the anchor's flight. When the anchor/mandrel combination is rotated in a first direction, the two elements will burrow as a unit into the ground. After the mandrel has been rotated sufficiently to put the anchor at a designed depth in the earth, rotating the mandrel in the opposite direction causes it to separate from the anchor and back out of the earth through substantially the same cut that was made when the anchor was turned into the earth. A preferred manner of applying torque to the mandrel is to utilize an electrically powered portable torque unit, in which the direction of rotation (clockwise or counterclockwise ...

Anti-theft device

An anti-theft device for use in open countryside, where there are no fixed objects to which valuables can be secured. The device relies on the principle that a helix when screwed into the ground cannot be pulled out easily and must be unscrewed. Two helixes are therefore screwed into the ground and locked together using an arm or arms. The resulting fixture is then used to secure a large object such as a bicycle or push chair, by means of a padlock and cable or chain. Alternatively, smaller objects such as jewellry or money can be held in a safe which also acts as the locking mechanism for the helixes. The arms may be locked together by a safe box 104.

In installation procedures the anchor rod is passed through the hub bore and the anchor member is operably coupled to the rod (as by resting it atop an outwardly extending shoulder provided on the rod); the tubular shank of a standard anchor wrench is next telescoped over the anchor rod and inserted into the hub bore such that a driving connection is established between the rod, shank and anchor member. Axial rotation of the wrench thus effects corresponding rotation of the screw anchor for installation purposes. The earth-penetrating lead of the screw anchor may be formed integrally with the major portion of the rod, or threaded thereon; in the latter case the overall length of the rod can be adjusted as desired. The modular nature of the screw anchors hereof permits stocking of only a relatively few standard components which can be used as needed in the field to achieve a desired anchor configuration.
