A guide for use in rock-cutting apparatus of the kind described, characterized by a ring (t²) through which the cutter can pass and which has arranged in conjunction with it a series of buffer springs, said springs acting on the ring and being capable of tensional adjustment, substantially as described. (7.) Rock-cutting apparatus comprising, in combination, a structure, a rock-cutter split at its upper end and connected with a winch by a hoisting-rope, means for controlling the action of the winch so as to raise and drop the cutter automatically, and a guide for the cutter, said guide being provided with a spring buffer-ring through which the cutter passes, substantially as described with reference to the drawings.

No. 21597.—8th August, 1906.—WILLIAM ERNEST HUGHES, of Queen’s Chambers, Wellington, New Zealand, Registered Patent Agent (nominee of Albert Holloway, of Melbourne, Victoria, Australia). Improvements in moulding-machines.

Extract from Specification.—The machine devised comprises a bed-plate, beneath which is mounted one of the feeding-rollers and which is so disposed that its periphery will project upwards through an opening in the bed-plate. A second roller is mounted above this roller on a parallel axis, and is kept normally in contact with the surface of the roller beneath by means of a weighted lever bearing on its axis. A disc embossed on its periphery, with the desired design, is secured to the end of this roller. A hood covers the top of the appliance, and means are provided whereby the flame from an oil or gas burner may be directed on to the edge of the disc, so as to heat the same.
