Abstract
635,215. Drilling-machines. DRAPAK, A., DRAPAK, O., and DRAPAK, J. Aug. 16, 1946, No. 24483. Convention date, Oct. 6, 1944. [Class 83 (iii)] In a dowel hole drilling-machine having a drill spindle bar 2 located below the work-table 7 and displaceable vertically with respect thereto, and a series of drill spindles 1 provided with common driving means arranged on the spindle bar 2, the work-table 7, which is provided with elongated openings 8, is adjustable laterally of the bar 2 by means of an eccentric disc 10 which bears against lugs 11 of the table 7 and is operable by a hand lever 12. The drill spindles 1 are interconnected by driving- belts 3 which are driven from a motor driving on belt pulleys 6, 6<SP>1</SP>. The work is clamped on the table 7 by means of a clamping member 14 having a displaceable clamping bar 13, the table 7 and bar 13 each being provided with a gauge. The spindle bar is raised and lowered by foot lever. The Specification as open to inspection under Sect. 91 states that the spindle bar may be curved. This subject-matter does not appear in the Specification as accepted.
