Abstract
947,620. Couplings for core drills. CRAELIUS CO. Ltd. Dec. 6, 1962 [Dec. 6, 1961], No. 43678/61. Heading F2U. A core drill 19 is driven by an adapter 10 through an intermediate annular member 14, the inner portion of which is screwed on to the adapter shank 12 so that rotation causes an' outer conical surface 15 on the member 14 to be wedged against a complementary surface 17 on a split tapered sleeve 18 in the end of the drill, or against such a surface formed in the end of the drill itself. A liquid sealing disc 21 is secured between the end of the drill 19 and a flange 13 on adapter 10, but this may be omitted in the case of a small diameter drill, the end of the latter then engaging directly with the flange 13, Fig. 3 (not shown).
