Patents of Interest to Builders.

SKYLIGHT— patent, No. 40335, has been taken out by Arthur Hopkinson, of New Plymouth, New Zealand. The invention consists in constructing the frame with an opening

extending along each of its sides, and in providing a cover for such opening that is pivotally supported in the frame so that it may he turned to uncover the opening or may bo left free to cover it. "...

REINFORCED-CONCRETE FLOORS, DECKS, ETC., CONSTRUCTION A patent, No. 40721, has been taken out by Evan Owen Williams, of London and Poole, England. According to this invention, use is made of the usual troughshaped moulds employed for shaping the slabs and ribs of

•U U movable supports arranged in connection with the scaffolding employed in such structures, so that while normally supporting the sides of the molds these supports are capable of being readily displaced at any desired moment, in such manner that each individual mould may be instantly freed and removed in downward direction. CONCRETE FLUMING —A patent, No. 40912, taken out by Walter Thomas Onion, of Parawai, Thames, relates to fluming so constructed that it may be supported upon trestleframing or foundations of any required design and without he necessity of employing means for fastening the fluming thereto. The fluming is of any channel-shape in- cross-section required, such, for instance, as semicircular, and along the outside of each edge is formed with a flange extending outwards for a short distance. These flanges serve as ledges that may be placed upon the horizontally extending members of a supporting trestle-frame so as to suspend the flum-ing-length between them and in a continuous line with the

remaining lengths of fluming to make the flume. Each legnth is also formed with an integrally moulded block on its under-

side, the bottom of which extends in a horizontal line, and is adapted to rest upon a transverse member of the trestle-

frame and more securely support the fiuming-length thereon. This block will allow for the fluming being laid and supported upon foundation or bed blocks of concrete or the like laid on the ground, .thereby dispensing with a 'trestle-frame if so desired. The fluming-length, in addition, is formed with transversely extending brace-members extending across between its top edges and moulded integrally therewith.

CONCRETE POST— A patent, No. 41243, has been taken out by Leader Vincent Orbell, of Waitaki, New Zealand. It consists of a post made in a mould, which may be opened on hinges or taken apart, the said post providing for the

securing of both plain and barb wires, and also for anchors ■or foot-pieces. The post may have strips for stapling or suchlike uses cast in same, together with any other nece&sary holes.
