April, 1909 mooring vessels alongside cidental to another or alongside one quays or wharves. In a vessel constructed in accordance this invention the topside tanks, are of uniform section through- disposed upon the upwardly inclined or sloping sides of the vessel and extended continuously from the poop to the after end of the forecastle. The t8ps of the tanks are carried in- wards to meet the sides of the vessel at a point below and clear of the joint between said sides and the hatch coam- ings, and the sides of the tanks are set back from alignment with the sides -of the vessel: In order to accommodate the tanks the sides of. rhe vessel are. with which out, are at or about the water line or a suitable distance above or below same, rounded or curved inwards and then inclined or sloped upwardly at a suitable angle and less in straight. lines, or 1m .a 9more or shell plating is connected. © Fig. 1, in the accompanying jaine. is an elevation of a vessel constructed FIG. 3. in accordance with the invention and in which the propelling machinery is arranged at the after end of the vessel. Fig. 2 is a half plan of the vessel, Fig. 3,. a diagrammatic amidships -- section, Fig. 4, a still further enlarged part sec- tion through one of tne hatchways, Fig 5, a detail, Fig. 6, a part perspec- amidships section of a vessel in which the. propelling machinery is amidships, 'form arranged "TAE /AARINE REVIEW forecastle and between the hatchways. In some cases the coaming plates may be extended downwardly and cover the ends of the frames, as shown in Fig 5. Above the sloping side o and set back from alignment with the faces g, shown in Fig. 4, of the lower portions of the sides of the vessel are disposed the sides h of topside ballast tanks j which are covered. by deck portions or- plat- forms k carried inwardly to meet the sloping sides at the points m below or clear of the coaming plates. By this construction or arrangement of the top- side tanks, the tanks are not liable to damage when the vessel is being moored or is lying alongside quays or other vessels, and water-tight flats within the bottom corners of the tanks, usually difficult. to' make and maintain water- tight, can be dispensed with. Hold pillars may be dispensed with by the employment at suitable intervals of web frames connected to hatch webs, but, when hold pillars are required or desired they may be connected to the frames and the shell plating clear of the tanks, as shown at m in Fig. 4. The up- per strakes of the plating of the sides of the. tanks are preferably flanged i over. the deck portions, and the Ne portions are flanged onto the shell plating of the sloping sides, as shown in Fig. 4, so that the joints are easy of to the are decked over access and readily calked. 4 4 The sides of the vessel and the sides ae 1 the: topside tanks are preferably par- allel and. without shear between the points o and p (Fig. 2) where the sides fall in at the poop and the forecastle respectively, so that the vessel is uni- in section between these points. At the poop and forecastle the sides h of the tank j merge into the ordinary shape of the vessel. Shear may be in- troduced to the bulwarks only or also 'to the poop deck, the forecastle deck and the bridge deck if desired. Amid- ships the vessel is a transverse saloon g : ~ eand a bridge deck. 1. tive view and Fig. 7 a diagrammatic _ ~The hatchways are made as long as possible consistent with strength, the winches for working the fore and after _ Referring to Figs. 1 to 6 a the eae ings, in a vessel constructed in accord- ance with this form of the. from the poop to the after end of the forecastle, \are rounded. or curved in- wards at\aypoint b at or about the water line, or ata suitable distance above or below same, and are inclined or carried up, as at c, to meet the bottom of the side coaming plates d of the. hatchways to which the frame e and -- shell plating f are secured. The coam- ing plates are continuous from the poop invention the sides a of the vessel, continuously -- 61 hatchways being arranged on the fore- castle and poop respectively, and those for working the central or amidships on the top of the saloon. Hollow posts t May pass up through the center of the saloon and the bridge to serve as up- tights for the derricks and also as hold ventilators. The bulwark plating uw, shown in Figs. 1 and 4, may be ar- ranged at a suitable distance above the deck portions, thus avoiding the use of bulwark ports or scuppers. In a vessel in which the propelling machinery is disposed amidships, as shown in Fig. 7, a casing w can be ar- ranged carried up to about the height of the bridge, throughout the length of the bunker spaces, and having inclined sides 4 forming shutes leading to the bunker hatchways y which also extend through the length of the bunker spaces and are provided with hinged or other suitable covers 2 adapted to be turned up as indicated to direct the coal, which is delivered onto the sloping sides into the bunkers. By this construction or ar- rangement the bunkers are self-trim- ming. Suitable guides may be provided to direct the coal clear of the funnel and the boiler room ventilators if de- sired, or the latter may be adapted to be removed and repaired by plugs when 'filling the bunkers. The top-side tanks may be arranged so that the water therein can be used in case of fire, and may be divided in- to compartments by water-tight divis- ions, some of which may be used as fresh water tanks. It is claimed by the inventor that vessels constructed on this principle, with continuous inclined or sloping sides and hatchways as long as practicable, will be "self-trimming" to a greater extent than vessels as hitherto constructed. DESIGN OF PROPELLER. The accompany nz crawings illus- trate a recent invention in propellers, the object being the provision of a propeller blade which will cause the water displaced thereby to be pro- jected in a solid stream in parallelism with the axis of the proseller, The blade is designed to prevent the loss of power due to the water passing off of the propeller blades at the top in- stead of at the rear edge, its curva- ture being intended to insure the course of travel of the water from the leading'to the trailing edges of the blade. In order to strengthen the propeller blade, and at the same time to secure a much moré positive action, ribs are provided which curve upon the blade in the are of a circle cocentric with the hub. ; shown. The blades are preferably
