prevented from being pressed out of shape after 

 leaving the cylinder, substantially as herein 

 described. 



4. The pipe-forming cylinder A, with its 

 piston D and lever E, in combination with the 

 flexible core F, attached to said piston by the 

 rod c, and provided with the cone-shaped ends 

 d d ', whereby the core or opening through the 

 pipe is formed smoothly and breakage prevented 

 in turning corners or on undulating ground, 

 substantially as herein described. 



5. The cylinder A, with a feed-tube, B, with 

 its splits or slots a and draw-band C, provided 

 with the hopper b and weighted hood G, and 

 having the piston D and lever E, said piston 

 having connectedwith it the flexible cone-ended 

 core F, the whole adapted to be placed in a 

 trench, along which it is moved by the action 

 of the lever and piston in forming the pipe, 

 whereby the pipe is made and laid at the one 

 operation and at the same time in a continuous 

 piece, substantially as herein described.
