Abstract

104,800. Fletcher, J. June 9, 1916. Augers.-A hollow auger for boring holes in tea chests, casks, &c., to facilitate taking a sample of the contents, comprises a shank 7, Fig. 2, carrying a centre pivot 9 and secured to receive a cup 4 and lock-nut 13. The sheet-metal cutter 2 is retained by a disk 10 and by screws passing through the cup and cutter and into the disk. Notches 3 facilitate the removal of the core. In a modification particularly designed for cutting through metal-lined boxes, the shank is tubular and contains a rod gimlet-pointed at 14, Fig. 5, and having a knob 18 projecting through a bayonet-slot in the shank. The screw point draws the lining against the case during cutting by a pair of extended knife-edged teeth 2<a>. The core is removed by turning till the knob can be pressed down the axial portion of the slot. According to the Provisional Specification, the bit may be employed for cutting out wooden wheels for toys.
