JUNE 29.] THE NEW ZEALAND GAZETTE. 2097

Extract from Specification.—According to our invention as applied to a furnace having a bridge rearward of the fire-bars, an air-chamber is constructed forward of the usual solid bridge, said solid bridge being used as the back of said chamber; the bottom of this chamber is open to the rear end of the ash-pit, its top side is formed of a heavy metal plate, and its front side is barred or grated with two series of vertical bars of T section fitted with spacing-paps, which bars are set in alternated order, to form zigzag air-passages leading from the air-box forwardly into the furnace. These bars subdivide and distribute the inflowing stream of air more or less equable across the whole width of the bridge, and raise its temperature, for which purpose they have a high efficiency. (Specification, 6s. 6d.)

Other features of the invention comprise improved constructions for carrying the invention into practice, and means for ascertaining the amount of power transmitted by the gears during operation.

No. 29595.—23rd May, 1911.—ERNEST SMITH BALDWIN and HENRIE HAMPTON RAYWARD, trading as “Baldwin and Rayward,” of 215 Lambton Quay, Wellington, New Zealand, Patent Agents (nominees of Kearns Manufacturing Company, a corporation organized under the laws of the State of Delaware, United States of America, having a place of business at No. 44 North 4th Street, Philadelphia, Pennsylvania, United States of America, the assignees of John Rea, of No. 1908 North 32nd Street, Philadelphia aforesaid, Mechanical Engineer). Improvements in and relating to dress-forms.

Extract from Specification.—The object of my invention is to produce a dress-form corresponding to that of a typical human figure from the neck to below the hips, which may be adjusted to lengthen and shorten the form, to contract and expand it at various points, and to vary its contour at any part thereof, either symmetrically or arbitrarily, to accommodate the form to all ordinary diversities of the human figure. Another object of the invention is to separately effect any particular local adjustment without incidentally effecting any other local adjustment, whereby any part of the form may be adjusted independently. Another object of the invention is to construct substantially the whole of the exterior skeleton of the form of material of maximum lightness, elasticity, and pliability extending substantially throughout the length of the form, so as to preserve the continuity and smoothness of the form under all adjustments while enabling it to readily flex and bend under the influence of the adjusting mechanism.
