December, 1923 lubricant which flows by capillary attrac- tion and centrifugal force from the cen- ter to the periphery. These wheels are equipped with guards, although they oper- ate at comparatively slow speed. They are iocated back of a table that serves as a tool rest. This is provided with a slid- ing tool holder which is equipped with a micrometer feed for the accurate finish- ing of plane bits, chisels and similar tools. The cone wheel and also a_ leather stropping wheel are mounted directly on the motor shaft. The cone is useful for finishing the inside of curved . edge tools, etc. The stropping wheel removes burrs and imparts a keen edge. The other end of the motor shaft accommo- dates a general utility grinding wheel. The machine is arranged so that four men can grind simultaneously.

The Welin Davit & Boat Corp., 305 Vernon avenue, Long Island City, N. Y., has for years constructed lifeboats of different’ types that could. be nested. The latest type of this char- acter is shown in the accompanying photo- graphs. Actually, it is more on the lines of a regular, full-bodied steel life- boat than any previous nesting boat. By holding the keel line practically par- allel to the sheer line, one of these boats will stow over another boat in a minimum of height and due to the rise of the keel at the ends will lie much closer to the ‘under boat. This will also simplify chocking and will re- duce the lifting of the boat to a mini- mum before launching with the davits. This boat is built of galvanized sheet steel with a flat outer keel, with two angle iron keelsons and an apron plate between the keel and the keelson to which the shell plating is riveted. The bottom shell is strengthened and_ stif- fened by floors, flanged to the shell plating, worked over the keelsons from bilge to bilge. The tops of the floors are also flanged to take the wooden footlings. This will give a straight walk- ing floor in the bottom of the boat - 475 and allow ample space between the shell and footlings to prevent the bad effect of wooden footlings in direct contact with the steel shell of the boat. Another new and interesting feature about the construction of this boat is the gunwales which are of angle iron. These gunwales increase the strength and rigidity of the boat. They also tend to keep the shell in contact with the gunwales from the deterioration which quickly sets up with oak gun- wales. The vertical leg of the angle is worked on the outside of the shell plate and riveted to the plate, consequent- ly making a perfectly watertight joint and not giving an opportunity for mois- ture to start corrosion. This boat has been so materially strengthened by use of flanged floors and angle iron gunwales that in suspension tests in loaded condi- tion the keel deflection is so slight that it can not be measured. This is the type of boat which was adopted for life boat accommodations in reconditioning the Lr- VIATHAN. FrANK C.
