Abstract

645,227. Drilling. WILL, J., and WILL, J. J. April 19, 1948, No. 10782. [Class 83 (iii)] [Also in Group XXIII] A device for drilling holes at given distances from a centre 1 and from each other comprises a pair of arms pivoted together at one end and connected together at their opposite ends by a rod, the length of which is adjustable, the arms being provided with adjustable slides each formed with a vertical aperture adapted to receive a drill or marking device. The arms A, B are pivoted at C and the angle between them may be adjusted by a third arm E which connects the ends of the arms A, B and is adjustable in length. One end of the rod E is provided with a milled nut F carried between the lugs of a bracket secured to the end of the arm A for giving a fine adjustment. Each of the arms A, B carries a slider O, P, which may be clamped in any position along the arms by milledheaded screws Q. A micrometer adjustment is provided for the brackets by extension screws R and milled nuts S in anchor brackets U. Vernier markings may also be provided on the brackets and the arms. Vertical bushes O<SP>1</SP>, Pi are provided on the brackets to take a drill, a marking instrument or a short rod adapted to be fitted into an already drilled hole. The stud C about which the arms pivot is provided on the top with a wing-nut for clamping the arms and an extension may be provided below for use in a datum hole.
