Not illustrated. 1922 Excerpt: ...distributed load that the core plates will carry, the student is advised to consult any engineers' pocket book or the schedules furnished by rolling mills producing these core plates, which will give the safe strength of the skylight bar. When finding the safe load, the span of the skylight, the distance the bars are placed apart and the exposure presented for wind pressure, snow, sleet and ice, must be considered. A ridge bar reinforced at e e is shown in Fig. 301 with a sheet metal core a. The joint between the glass and bar is protected from leakage by the cap c b d fastened as previously described. If desired the bar and cap may be made in one piece, Fig. 302. Note carefully, how this bar is bent. The walls of the bar are held firmly by the reinforcing strip A A with caps formed at B B, then closed with a standing seam at D. Soft putty is inserted between the cap and rabbet of the bars and the glass C C pressed in, which will make a tight job. In the five illustrations next shown, the various shapes of curbs which may be modified to suit the pitch as occasion may demand. The simplest form for small size skylights is shown in Fig. 303, and is bent in one piece from A to B, with a cap flange resting over the wooden curb C, through which screws are inserted at D. Holes for the escape of the condensation are punched at E, allowing the drip to run to the outside. Note that bar F miters to the curb from A to G, as shown by the dotted lines, and gutter b in bar F is notched at c to allow the drip from the bar to flow into the gutter of the curb as shown by the arrow. When this style of curb is used and the doubled metal at a is not soldered, it is well to make a few notches, as at /, to allow any drip running between the folded metal at a, to escape at e. Anoth..
