Abstract
13,799. Witchell, E. J., Witchell, A. P., and Jones, F. A. June 12. Lattice-work. - In metal lattice-work formed of bent metal strips riveted together as shown in Fig. 1, certain parts F are not twisted but left to show the broad surface, thus producing geometrical patterns. In order that the frame C in which the structure is mounted may fit closely in the opening A, the scroll pieces H are not secured to the framing by rivets, but by one or more tongues G, J punched from the frame and bent over as shown in Figs. 4 and 6. In a modification, a separate securing-piece K is employed, the edges of the hole in the frame being upturned, and the piece K inserted as shown in Fig. 8.
