Abstract
675,339. Drilling square holes. FRIES, R. Oct. 4, 1950, No. 24213/50. Class 83 (iii). A device for drilling square holes comprises a triangular drill 1 working in a square-section window 2 which is detachably mounted in a housing 5. The housing carries posts 6, 7 on which a bridge-piece 8 is slidably mounted. Centres 13, 14 position the device on a workpiece. In operation, a shank 22 is connected with an electric hand drilling-machine and the device is held by the handle 12. For drilling inclined holes the handle 12 is replaced by an angularly-adjustable clamping-device 26, 28. If the drill has little flexibility a universal joint may be incorporated in the drive. In a modification for use in drilling true holes, the drill 1, Fig. 9, is driven via keyed plates 40, 42, 45 which allow the drill to follow the window without flexure. A rod 33 slidably supported in the housing 5 carries adjustable clamps 35, 38 for securing the device to a work-piece. A handle is also provided on the housing 5. Drills. The fluted drill 1, Figs. 6 and 7, has an end-face fashioned, as shown, in the manner of a milling-cutter. The drill of Fig. 9 has a screwed shank for attachment to the plate 40.
