It will benoticed that the outline of the cornice only is shown, being allthat is required to locate the various sizes. These measurementsare used in the shop by the cutter to lay out the various piecesand by the bench hand to mark off and locate the positions ofthe brackets, modillions and panels when setting the cornicetogether. Assume that a cornice on a building is to be 25 , with four windows across the front, the measurements. Fig. 164-5. Fig. Methods of Locking Seams. having been obtained at the building. It will be noticed that abracket is on each end, and one over the center of each pier. The first step in getting the dimensions for the cornice is toadd together the widths of the piers and windows, which in thiscase amount to 25 ft. As the three brackets are to come overthe center of the piers, add together the width of the end pier,the window and one-half of the next pier, as 2 + 3 -f- 1 ft. 6 6 ft. 6 in. Then 1 ft. 6 in. + 3 + 1 ft. 6 in. = 6 ft. Thesemeasurements answer for the opposite side also. Prove thesefigures by adding 6 ft. 6 in. + 6 ft. + 6 ft. + 6 ft. 6 in. == 25 locate and mark the face of the brackets and modillions by10 and 6 in. In this case it is assumed that the distance from 122 Home Instruction for Sheet Metal Workers
