Construction machine
First Claim
1. A construction machine for use in the controlled distribution of formable concrete along an elongated transversely limited site having a base surface of a predetermined configuration and a predetermined lateral dimension, said machine comprising:
- a main frame for movement longitudinally along the base surface, said main frame including a front section and an elongated trailing section extending substantially rearwardly therefrom, said sections overlying the base surface on which the formable concrete is to be distributed;
propelling means mounted beneath said main frame and adapted to be supportingly engaged by the base surface as said frame moves thereacross;
a first hopper means mounted on said frame front section and overlying such base surface to receive a load of formable concrete from a source independent of and positioned forwardly of said machine on the base surface on which said concrete is to be distributed;
an elongated mule mounted on said frame trailing section and extending laterally therefrom and being spaced a substantial distance rearwardly of said first hopper means and rearwardly of said propelling means, said mule overlying such base surface and including a second hopper means having an undersurface conforming substantially to the predetermined configuration of the base surface in supporting engagement with said propelling means;
conveying means carried on said main frame and extending from said first hopper means to said second hopper means in a direction generally longitudinally of said construction machine for controlled rearward transfer of formable concrete from said first hopper means to said second hopper means;
vibrating means operatively mounted on said second hopper means; and
control means mounted on said main frame and operatively connected to said propelling means for controlling relative movement and steering of said machine along the base surface, whereby concrete delivered to such machine from a source on such base surface forward of said machine is placed on said base surface by said mule at the rear of said machine.

Abstract
A construction machine is provided for use in the controlled distribution of formable concrete along a base surface of predetermined configuration. The machine includes a self-propelled main frame movable along the base surface. The main frame is provided with a front section and an elongated trailing section extending rearwardly therefrom. A first hopper is mounted forwardly of the frame front section for receiving a load of formable concrete. An elongated mule is mounted transversely on the frame trailing section. The mule is spaced a substantial distance rearwardly of the frame front section and includes an elongated second hopper having the underside thereof conforming substantially to the predetermined configuration of the base surface. A conveying means is carried on the main frame and effects controlled transfer of the formable concrete from the first hopper to opposite end portions of the second hopper. Vibrating means is carried on the mule. Control means is mounted on the main frame for controlling relative moving and steering of the machine along a prescribed path on the base surface.

16. An apparatus for placing formable concrete on an elongated base surface, said apparatus comprising:
- a movable main frame for movement along such a surface in overlying relation thereto;
propelling means mounted beneath said main frame and adapted to be supportingly engaged by the base surface as the said frame moves over said base surface;
a mule spaced a substantial distance rearward of the rear distal end of said main frame for overlying said base surface and having a hopper with an undersurface conforming substantially to the predetermined configuration of the base surface;
support means spaced laterally of said main frame and fixed to said main frame for cantilevered support of said mule in such substantially rearwardly spaced position, and for providing substantial workspace for placement of reinforcing materials on the base surface between said main frame and said mule, said mule subtending said support member; and
conveying means carried on said support member for controlled rearward transfer of concrete from said main frame to the hopper of said mule. - View Dependent Claims (17, 18, 19, 20, 21)
