No. 17249.—17th November, 1903.—JAMES WATSON, of 52, Murphy Street, Wellington, New Zealand, Designer and Sculptor. Improvements in shop-window frames.

Extract from Specification.—I lay the metal tube in the groove of wood strip, then place the round steel rod which is a neat fit inside of tube and screw them securely together by means of screws in every other corresponding holes of wood strip and tube. I also tap the steel rod so that the screw may enter a certain distance. In the putting together of the shop window-frames I attach a plate of iron by means of screwing same to each end of the perpendicular or upright sash-bars, which is then placed in position either against concrete or wood supports and firmly screwed thereto. The wood strip, as shown by letters C, may be made to any suitable design. It will be seen by these that although the form and size vary, according to strength or appearance required by architects, in every instance they have the invariable accompaniment of a metal tube with a steel rod placed therein.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
