The structure of the brace being ex- 5 tremely light will enable a light truss to be produced and, at the same time, will very rigidly connect these elements.
Since the construction hereinbefore set forth is capable of a certain range of change and modification without materially departing from the spirit of the invention, I do not limit myself to such specific structure except as hereinafter claimed.
I claim r l 1. A truss brace comprising atrough, sock ets secured to the sides of the trough and extending below the trough, flanges secured to the socket below the trough and at the verticalcenter of the trough and sockets, and
means connecting the flanges together.
2. A truss brace comprising an elongated trough, sockets secured to the sides of the trough centrally between the ends of the trough, the sockets extending below the trough, and flanges extending from one socket to the other at a point below and atthevertical center of the trough and sockets.
3. A truss brace comprising sockets each embodying an outer wall, side walls and a top '30 wall, the top walls being connected at their outer edges to the upper edges of the outer walls, and the side walls having the upper portions of their inner edges arranged vertically and thelower portions of said edges inclined downwardly and outwardly, a
trough arrangedbetween said vertical edge portionsand having the upper edges of its sides connected to the inner edges of the top walls, upper flanges secured to said vertical edge portions and to the sides of the trough,
lower flanges securedto said inclined edge portions, and flanges secured to said lower flanges and arranged in overlapping relation and secured together, said last flangesbeing arranged at the vertical center of the trough and sockets. v i Y Y In testimony whereof I hereunto affix my signature.
