No. 19411.—1st May, 1905.—GEORGE HENRY CLAPHAM and JOHN LANCELOT BARLOW, both of Wellington, New Zealand, Metal Workers. Improvements in spouting brackets.*

Extracts from Specification.—Our invention has been designed to carry out the aforesaid object, and to this end we construct the bracket proper of one piece of metal shaped or moulded to the contour of the spouting, and having a portion adapted to lie next to and vertical with the structure. . . . The top of the moulded portion of the bracket is slit or cut vertically in two places, and the part thus cut is bent downwards and outwards, thus forming a small lug or ear. This lug or ear is adapted to fit into a slot formed in a clipping piece, which is retained thereby, and this clipping piece is so shaped that it may be turned over the edge of the spouting and securely hold the spouting to the bracket.
[NOTE.—The above extracts from the specification are inserted in place of the claims.]
