LAKE SHIP YARD METHODS OF STEEL SHIP CONSTRUC- : TION. BY ROBERT CURR. DECK HOUSES. Fig. 119 shows the deck house aft -- completed. Fig. 120 shows the interior of the after deck house, viz.: The spar deck plating, stairway, engine casing, boiler and coal bunker bulkheads and openings, deck house coaming angle and spar deck beams cut at edge of same. Fig. 121 shows plan of steel top of deck house. One mold is made for half of the longest beam and the holes are so arranged that the one mold serves the purpose of marking all the beams on the top of house. For the lengths of the beams a bat- ten is used for the width of the house at every beam and the bracket mold is applied to same which gives the bevel of the beam end as well. The top angle of the side plating has -a universal pitch of rivets for the deck "the rivets coming in line with the beam holes--inway of same. The same arrangement of rivet holes is made on the outside angle which is fastened on the edge of the plating projecting over the sides of the house. In this case the centers of the holes are lined in on the top plating and the beam hole mold applied to same. Measurements are given for the curve of the outside angles and as the rivet holes are universal very little trouble is experienced in laying out © the deck plating with strips. Fig. 122 shows the starboard side of the after deck house. One mold serves the purpose of marking all the holes for stiffness and the holes} for the pilasters. The top and bottom angles having a uniform pitch of rivet holes e ~ THE Marine REVIEW, weeccccee-o-2-t-2! requires only two molds for marking the whole side of the plating. All that is required for marking the plates are the widths and*top and bottom bevels, one measurement being all that is necessary for whatever curve may be in the center of the plate. One mold is all that is necessary for marking all the pilasters. The pilas- ters are usually left one-eighth of an inch long top and bottom and the flange of 'the angles chipped to remove the slightly beveled edge on the flange of the angle. Fig. 123, shows the port- side of the after deck house which is marked with the same molds used for the starboard side. Fig. 124 shows the fore end of the after deck house which is treated simi- larly to the side plating. The butts are all perpendicular so that the bevel of the top and bottom are worked from same. Fig. 125 shows the after end of the deck house which is treated similarly to the fore end, Fig, 124. To get the proper shape of the deck house plating the heel of the coaming
