No. 16560.—24th June, 1903.—WILHELMINA ROBERTSON, of Maori Hill, Dunedin, New Zealand (executrix of the will of William Robertson, late of Maori Hill aforesaid, Settler, deceased). Improvements in flue-dampers.*

Claim.—Improvements in flue-dampers, consisting of slats pivoted in a frame adapted to be opened and closed by a sliding rod, and such that when closed each upper slat slightly overlaps the one below it, leaving a small substantially vertical opening between them, substantially as described.
(Specification, 1s. 9d.; drawing, 1s.)

No. 16726.—1st August, 1903.—WILLIAM BENJAMIN WALTERS, of Mornington, Dunedin, New Zealand, Engineer. An improved carburetter.*

Extract from Specification.—According to this invention the air or gas is led nearly to the bottom of the carburetter through a pipe furnished with a rose, which pass through the hydrocarbon contained in the carburetter. Around the cone, of which the said rose forms the base, are placed a number of spheres, preferably marbles such as are used for playing games. The air or gas passes freely through the rose and through the interstices between the marbles, during which passage it is thoroughly broken up and brought into intimate contact with the hydrocarbon. Two carburetters are preferably used, as less pressure is then necessary to force the gas or air through the hydrocarbon, and better results are obtained in enriching the air or gas.
[NOTE.—The above extract from the specification is inserted in place of the claims.]

Improvements in fluid-pressure turbines.

Claims.—(1.)

(2.) In a cultivator, the combination of the axle, a horizontal loop formed on or connected to the front of the axle, the tongue, a downwardly facing hook secured to the rear end of the tongue and adapted to be engaged with the aforesaid loop, and a keeper adapted to fit between the hook and the axle, substantially as described. (3.) In a cultivator, the combination of the main frame, a cultivator frame or section pivoted at its forward end to the frame of the machine, a substantially vertical connecting-rod pivotally connected at one end to the said section, a substantially horizontal pivoted link adapted to retain the connecting-rod in its vertical position, a coil spring adapted to exert a downward pressure on the said connecting-rod, and having its line of draft out of line with the connecting-rod, and means for changing the tension of the spring, substantially as described. (4.) In a cultivator, the combination of the main frame, a cultivator frame or section pivoted at its forward end to the frame of the machine, a substantially vertical connecting-rod pivotally connected at one end to the said section, a rock-shaft, an arm on the rock-shaft, a link pivotally connected to the connecting-rod and to the said arm near the shaft, and a spring engaging the link and the said arm at or near its end, the spring being adapted to exert a downward pressure on the link, substantially as described. (5.)
