Abstract

1,184,106. Reamers. JOHN DARBYSHIRE & CO. Ltd. 9 April, 1968 [18 April, 1967], No. 17710/67. Heading B3C. A reamer for undercutting blind holes in underground workings so as to secure bolts by adhesive, comprises a shank 1, Fig. 1, slidable against a spring 11 in a housing 4, cutter blades 20 pivoted to the shank at 21, and a blade opening stop 6, fixed to the housing at 8. Stop 6 and cutter blades 20 are removable. In a modification, blades 20 are pivoted to housing 4 at 25, Fig. 4, and shank 1 is moved against the blades so as to expand the latter. On retraction of the shank the blades are retracted by rubber or synthetic rubber compression members 27.
