ABSTRACT:
A round pen and the method of constructing the same which comprises the steps of selecting a plurality of vertical round tubular steel posts, a plurality of horizontal rails of tubular steel and a plurality of cables of sufficient length to traverse the distance from the first end post around the intermediate posts and back to the second end post, each intermediate post having a series of eyes welded thereon, fitting the cables through all of the eyes on the intermediate posts and attaching an end of each cable to the first end post, attaching an opposite end of each cable to the second end post through a spring, inserting an end of a horizontal rail into an opening in the first end post and then adjusting the opposite end of the rail into an opening in the next adjacent intermediate post, continuing to insert horizontal rails in all of the intermediate posts until the rails are in abutting relation in all of the intermediate posts, inserting the ends of a horizontal rail in an opening in the second end post and into an opening in the last intermediate post, inserting retaining pins within vertical holes located adjacent the ends of the rails within the intermediate posts to prevent the rails from slipping out of the intermediate rails, placing the cables under tension so that the rails are placed in compression between the posts, thereby preventing the pen from collapsing and providing rigidity for the pen structure.
