## Abstract

The present invention provides an adjustable bolt-on brace attachment for strengthening standard field irrigation towers and tapered sections of field irrigations towers to stabilize a tower. In one aspect of the present invention, an attachment for stabilizing field irrigation towers allows the user to easily assemble the adjustable bolt-on brace in the field wherein three threaded ¾ inch rods span between the each of the three weight bearing poles of the field irrigation system. Each ¾ inch threaded rod is spanned between each pair of weight-bearing poles of a tower attaching at each pole by a galvanized steel two-sided clamp which is double bolted-on to each pole. The adjustable threaded rods may span from 15 inches to 49 inches of each of three tower faces and adjustable double sided steel clamps fit field irrigations tower legs sizes from ⅞ inch to 2½ inches diameter.

## Claims

### Claim 1

An apparatus for stabilizing a field irrigation tower, wherein the apparatus comprises three threaded rods with double-bolted clamps configured to form an adjustable collar around the legs of the field irrigation tower, the apparatus comprising:
a first threaded rod having a proximal end and a distal end; wherein the proximal end of the first threaded rod comprises a first galvanized clamp; wherein the first galvanized claim is comprised of a pair of wall clamp members adjustably attached by at least two clamp securing bolts; further wherein the distal end comprises a second galvanized clamp; wherein the second galvanized claim is comprised of a pair of wall clamp members adjustably attached with at least two clamp securing bolts; wherein the first galvanized clamp is substantially parallel to the main axis of the first threaded rod; wherein the second galvanized clamp is substantially parallel to the main axis of the first threaded rod;
a second threaded rod having a proximal end and a distal end; wherein the proximal end of the second threaded rod comprises a third galvanized clamp; wherein the third galvanized claim is comprised of a pair of wall clamp members adjustably attached by at least two clamp securing bolts; further wherein the distal end comprises a fourth galvanized clamp; wherein the fourth galvanized claim is comprised of a pair of wall clamp members adjustably attached with at least two clamp securing bolts; wherein the third galvanized clamp is substantially parallel to the main axis of the second threaded rod; wherein the fourth galvanized clamp is aligned to create a sixty degree angle between the main axis of the fourth galvanized clamp and the main axis of the second threaded rod; and
a third threaded rod having a proximal end and a distal end; wherein the proximal end of the third threaded rod comprises a fifth galvanized clamp; wherein the fifth galvanized claim is comprised of a pair of wall clamp members adjustably attached by at least two clamp securing bolts; further wherein the distal end comprises a sixth galvanized clamp; wherein the sixth galvanized claim is comprised of a pair of wall clamp members adjustably attached with at least two clamp securing bolts; wherein the fifth galvanized clamp is substantially parallel to the main axis of the third threaded rod; wherein the sixth galvanized clamp is aligned to create a sixty degree angle between the main axis of the fourth galvanized clamp and the main axis of the third threaded rod.
