Self-propelled construction apparatus
First Claim
1. A self-propelled construction apparatus for continuously forming a paving material onto a suitable surface such as the ground, said apparatus comprising a main frame including a body having a front end and a rear end, a prime mover carried by said body, a molding means connected to said main frame for continuously forming paving material, at least one pair of independently and longitudinally adjustable substantially horizontal beam members directly connected to said body at one of said ends and defining one end of said main frame and wherein each of said beam members of said pair is adjustable independently of the other beam member, front and rear movable ground engaging means, and means connected to said ground engaging means for connecting said ground engaging means to said main frame at respective ends thereof for supporting the main frame and for varying the height of the main frame above the ground.

Abstract
A self propelled construction apparatus for continuously forming a paving material on a suitable surface such as the ground. The apparatus is capable of performing a variety of molding operations. The main frame of the apparatus is so constructed as to be adjustably extended outwardly longitudinally for wide width paving. Also, the apparatus can be laterally adjusted to perform narrow width paving. The apparatus may have an offset mold on either side thereof for offset molding or a mold underneath the main frame for molding between the ground engaging means. Further, means for mounting and connecting the mold to the main frame allows the mold to be moved angularly on a vertical axis from an operative position alongside the main frame to a transport position at the end of the substantially aligned with the main frame.
