Abstract
A machine for sawing stones, of the kind having one or more reciprocable blade-carrying frames, is disclosed, wherein an actuating mechanism for said blade-carrying frame is provided, which moves said frame(s) substantially parallel to itself along a preselected elliptical path. A few embodiments of the machine are disclosed: one of these presents quite particular an approach by which the stresses on the pivotal and connection pins are considerably reduced by exploiting appropriate balancing contrivances, such as counterweights located at appropriate points of the specially provided balancing connecting rods. A longer service life is thus provided both to the blades and the machine as a whole.
Claims5
A machine for sawing blocks of a solid material, more particularly stony materials, said machine comprising a movable frame for supporting a plurality of parallel toothed blades, and frame actuating means for moving said frame along a preselected substantialy elliptical path, said frame actuating means comprise at each side of said blade-carrying frame a pair of wheels having continuous concordant rotary motions around parallel fixed axes, a pair of remote sliders and a pair of connecting rods one end of each of said connecting rods being pivotally eccentrically attached to a respective one of said wheels and the other end of each of said connecting rods being pivotally attached to a respective one of said pair of sliders, means mounting each of said sliders for movement rectilinearly parallel to a line between said axes of the wheels, said connecting rods being of substantially the same length and having a side of said blade-carrying frame pivotally attached thereto at respective points substantially equally spaced from said other end of said connecting rods.
