No. 16977.—15th September, 1903.—CHRISTOPHE SOULAS, of Jerusalem, Wanganui, Wellington, New Zealand, Priest. An improved wave motor.

———

Extract from Specification.—This invention relates to apparatus employed for utilising the action of the waves as motive power. In my invention I employ a float designed to rise and fall with the waves, to which is connected a piston reciprocating vertically in a cylinder fixed above the float. A rod connects the piston with a rack having two sets of gear-teeth engaging with pinions actuating ratchet wheels fixed upon horizontal shaft from which the power is taken. Each of the pinions is operated independently by one of the sets of teeth in the rack, so that the shaft is revolved by rise and fall of the float. Water is drawn into the cylinder referred to by the reciprocation of the piston and forced into a reservoir at considerable height above the sea-level, so that the water therefrom may be utilised to drive a turbine or other water-motor.
[NOTE.—The above extract from the specification is inserted in place of the claims.]

Claims.—(1.) In the working of an ore-roasting furnace, utilising heat from the gases of combustion from over the hearth by conducting them along said hearth’s under-side, as set forth. (2.) In an ore-roasting furnace having its rabbling devices above the hearth, a sub flue or flues beneath said hearth, in contact therewith, communicating with the furnace, from which hot gases are adapted to pass through said sub flue or flues to a chimney or exit, substantially as and for the purposes set forth. (3.) In an ore-roasting furnace having rabbling devices, a hearth above a sub flue or flues adapted for the passage therethrough of the hot gases of combustion from the furnace, and means (as dampers) to regulate the said passage of the hot gases, or to lead them from the furnace direct to the chimney or exit, substantially as set forth. (4.) In an ore-roasting furnace, the improved rabble foot and stem integrally partitioned, as illustrated, and as above set forth.

Extract from Specification.—A general arrangement of mirrors and screens to form a maze of tortuous passages, some of which are real and some reflected; the combination of a mirror and the half of an arch, or the halves of two arches, springing from said mirror, the other part of the arch or arches being produced in the mirror by reflection. A tapering tunnel, having an inclined mirror at its smaller end, whereby the effect of extreme length is produced, and a mirror at some distance from its larger end which reflects the whole length of said tunnel. An arrangement of two mirrors fixed approximately at right angles to each other, with their corresponding edges bevelled and meeting, the point of juncture being practically invisible. The joined mirrors are arranged behind a plate-glass screen, in front of which are other independent mirrors, the effect being that a person walking towards the joined mirrors appears to be walking away therefrom, and vice versa. A cave, entrance, or arch of comparatively small depth, which has an inclined mirror at its foot, by means of which the appearance of great depth is obtained. A scenic tableau comprising a frame having an opening covered with plate glass, behind which is a screen adapted to conceal an object which is reflected into a mirror placed at an angle of 45° with said opening.

In a machine of the kind described, a wheel that is revolved at a predetermined rate of speed, a plurality of holes in the wheel-rim that are numbered; a fixed dial and numbered dockets, the dial having means, situated radially from said holes, for securing the numbered dockets thereupon; and an index finger or pointer co-axially situated with the wheel and revolving therewith, but which is capable of being adjusted independently of the wheel when desired, as specified, and for the purposes set forth. (3.) In a machine of the kind described, a wheel that is revolved at a predetermined rate of speed, which has holes at regular intervals in its rim wherein pins or pegs may be inserted, an index finger revolving with the wheel, which index ranges over a fixed dial having means for supporting figured dockets, in combination with a trip lever which the pins in the wheel-rim can each in turn engage, and by means of which mechanism is operated to revolve spools carrying an endless band and to ring a gong, as specified, and for the purposes set forth. (4.) In a machine of the kind described, a pair of spools mounted upon parallel spindles that carry a band bearing numerals, a drum upon the upper spindle that is directly actuated from a weight attached to a cord, and a snail cam upon the lower spindle that normally bears against a cross-piece in a slotted rod, and means for raising the rod so as to release the cam and thereby permit the spools to revolve, as specified. (5.) In a machine of the kind described, a pair of spools mounted upon parallel spindles that carry a band bearing numerals, a drum upon the upper spindle that is directly actuated from a weight attached to a cord, and a snail cam upon the lower spindle that normally bears against a cross-piece in a slotted rod, means for raising the rod so as to release the cam and thereby permit the spools to revolve, a stud upon one of the spool-flanges, a bell, an arm spring-mounted so as to be normally in contact with or near to the bell, and a finger in connection with said arm that is engaged by the stud aforesaid and released as the spool revolves, as described and for the purposes set forth.
