Abstract

1,063,718. Cores for making holes in concrete. C. L. HAGEDORN. Aug. 31, 1964. [Sept. 4, 1963], No. 35536/64. Heading E1S. For making holes of different lengths in concrete one or more tubes are used, the external diameter of one end of each tube being the same as the internal diameter of the other end so that the smaller end of one tube can be engaged in the larger end of another tube and an external circumferential ridge on the smaller end engages in an internal groove in this larger end. The base of the outer tube engages the ledge between the two parts of the tube and may have a flange for securing to shuttering. The small end of the tube may be closed. The tube is made of synthetic plastics material.
