Definitions
- One of the objects of this invention is to provide a machine for continuously forming a pipe of concrete in a previously dug trench, such, for example, as shown in my Patent 2,969,576 issued Ian. 31, 1961.
- Another object is to provide a continuous concrete pipe laying machine which travels along in a trench and which receives the plastic concrete mud or other suitable material and automatically forms a continuous pipe thereof in the bottom of the trench as the machine is moved along in the trench.
- Another object of this invention is to continuously cast a concrete pipe in a pre-dug ditch while using a sectional pre-set inner core over which travels the pipe forming machine in forming the pipe.
- FIG. 3 is a front elevation of the machine indicated by the line 3 3 in FIG. 1.
- FIG. 8 is a fragmentary section on the line 8 8 of FIG. 1.
