Abstract
785,465. Drilling-machines; jigs. WIESNER, R. A. March 13, 1956 [Dec. 14, 1954], No. 36230/54. Class 83 (3). An attachment to a single-spindle drilling- machine to enable flat, brittle articles such as glass, tiles, &c., to be drilled from opposite sides, comprises a pilot 15 which may be projected through the work-support 3 to engage a partly-drilled hole in the work after it has been reversed on the support, to locate the corresponding part of the undrilled side of the work under the drill. An interchangeable pilot 15, similar in size to the tubular diamond &c. drill, is a push fit in a cap 14 screwed at 6a to a cylindrical block 6, rotatable and slidable in a bush 4 secured at 5 to the drill-table 1. The pilot projects through holes in wooden and felt work supports 2, 3 respectively. A key 10 is adjustably secured in a slot 9 in block 6 by a nut 12, which engages an inclined slot 11 in bush 4, so that rotation of the block by a handle 13 causes the pilot to project above support 3 into the partly-drilled hole in the work, or recede into the support. An ejector 16 ejects the core from the pilot or support 3, and a spring may assist withdrawal of the block 6. Removing cuttings. Axial grooves 8 in the block 6 allow slurry, cuttings, &c., to escape.
