pressed together, or if they need to be opened or moved in another direction it can be done by pulling out or twisting the handle of the tongs.
In Figs. 70 and 71 are shown grilles which have been worked in the manner described for forming flat scrollwork. Fig. 72 shows a sketch of a corner for a grille to be made from flat stock. The design consists of a frame with the surface divided into nine rectangles. The center rectangle is filled with an ornament consisting of the circle and scroll combined in one and repeating itself throughout the central square. The ornament may be made from one piece of stock or it may be of two pieces. The corner ornament is in the form of a rosette and made of two pieces. The border is filled with a scroll pattern repeating itself throughout. The method of fastening these forms in place is with the band, excepting the outer edge, which is riveted.
In Fig. 73 are shown a number of ornamental forms based on the circle and made from flat stock. Forms from flat stock are very simple to make unless the members are welded. Grille work made of flat stock presents a very pleasing appearance. By viewing the grille from the narrow edge first we get the idea of delicacy. An increasing sense of strength is obtained with the constantly varying profile as viewed at different angles.
