376 head of the gravity tanks, on account of the automatic valve. The cooling coils cannot be removed without disturbing the ceiling and insul- ation at the bottom. The two heavy plates at the bottom of the scuttle butt, above and below the insulation, are undesirable if they can be avoided. Fig. 6 shows how they can be avoided. : There is a long lead of piping from the scuttle butt to the drinking geyser. The water standing in this piping gets warm, necessitating in the course of the day quite a waste of water to obtain a cool drink. The geysers are not sanitary. The lips of the drinker frequently touch the inside funnel as well as the nozzle. The self-closing cock is said on board ship to require frequent overhauling. The type of geysers shown on Fig. 6 is similar to that fitted to the experimental scuttle butt on SoutH Carorrna, these Arrangement OF Geyser Y Dy Lae” wart i eLssteNN GH, UU SSS ee ae THE MARINE REVIEW geysers having been installed at the Norfolk navy yard. It is reported on the vessel that they are very much more satisfactory than those according to the standard plan and that they require very much _ less attention to keep in good condition. The modifica- tions of the Norfolk type that are em- bodied on the enclosed plans are those that have suggested themselves after an investigation of the experimental instal- lation on SouTH CAROLINA. No drip pan is fitted on the experi- scuttle butt on SoutTH Caro- LINA. The omission of the drip pan is said to be a complete success. The scuttle butt is located over a_ tilted space, and the waste funnel of the drinking geyser is large enough to catch all the drip. The waste funnel mental of the proposed geyser is somewhat larger than that tested on SouTH CaroLinA. The drip pan is at best an unsanitary as well as unsatisfactory fea- Sil il ESS CHAT November, 19]6 ture. The angle iron ring around the bot. tom of the scuttle butt rusts out badly in the vicinity of the geysers. Water finds its way behind the toe of the angle rusting out the celling as well as the angle. This construction is not used in the proposed type. The hand holes in the top and bot- tom of the scuttle butt are an unneces- sary expense. The pipe plug shown in Fig. 6 is sufficient for ordinary drainage, while the ease with which the top can be removed facilitates periodical clean- ing out of the scuttle butt. It will be noted that the supply pipe has been led in.through the side of the scuttle butt, so as to leave the top free. It will be noted that the reinforcing rings at vari- ous points in the scuttle butts are acetylene welded thereto, permitting the pipe to be removed and replaced without any interference with the insulation or sheathing.
