Abstract

187,836. Archdale & Co., Ltd., J., and Jewsbury, J. Oct. 19, 1921. Drilling-machines.- In radial-arm drilling-machines of the type wherein the outer end of the arm is supported by a stay, the stay a carries a roller or rollers c bearing on a circular track e, attached to the bed f. The roller is adjustable by reason of its spindle being mounted in an eccentric bush n, locking being effected b screws j. k. A plate g takes the upward thrust when the drill is in operation and may be used to clamp the arm, in conjunction with a screw h. A cover-plate is provided, to which are attached felt pads for cleaning the track. Instead of the eccentric bush, an eccentric spindle may be employed.
