By reference to the midship section it will be seen that the shell plating strakes are all lettered alphabetically from the keel and numbered from the fore end similar to the rest of the material on the vessel. - This plan shows all the girders, longitudinals and decks which are 'connected to the shell plating. From 'frame. No. 5 to No. 136. the 'vessel is the same width so that a great number of.plates in the bottom are the same size and can be laid off with one mold, but I understand that this firm uses strips for marking all the shell plating on the vessel. : - Level lines are used on the plates about the center of same and. the frame strips for the rivet holes con- necting frames to plating are applied to same. These strips give the width of the plates and location of all lon- gitudinals which are marked upon the Strips. in the bottom dre strip 23 $-5-] Bs | Ghade to Extend over ¢ x i *2 SECTION THRO Window For'd of Door a PILOT HOUSE 0 jartie DEE : Pored ieee SUN SHADE AROUND PILOT HCUSE; 'mark the frame holes are CONSTRUCTION ae ROBERT CURR, OUT'D SHELL EXPANSION Bic, 13; serves the purpose of marking all the frame holes' on the plate because of the plate being square.

Strips for the plate laps are made in one length, changes being made in the spaces where the butt laps are located, seeing the butt laps ave less in' width than three «spaces "of rivet holes. The molds used for laying off the shell plates are seam, frame, butt lap and girder molds and these molds are $0 arranged that. there is:-very little chance of error in marking the plate. The level dine is. put on: and -the frame heels squared from same. The frame mold is applied to these lines, marking all the holes for the frame rivets in the width of the plate. The lap holes serve the purpose as a guide for applying the-seam mold.

The time is not far distant when they will put on every shell plate from molds laid. out in the mold loft. Fig. 14 shows the-steel deck houses which are all completed from molds made in the mold loft.
