Application inea November 1 19192915 "ser'iai branca-ais@ This invention relates to a runwaycon# struction for seaplanes" and airplanes of the amphibian type.

It is an object of the invention to provide v [5; a construction or lmeans whereby such planes maybe quickly launched or'broug'ht out of the water and in addition to provide a construction wherein theV time required for ini Stallation is reduced-'to a minimum.

Another object is to provide a noveljconstruction wherein maximum use -is made of pre-cast and pre-built units to be used, the

construction enabling most of the assembly ofthe apparatus to take place out of the water 16 be accomplished by sliding movement.

Another object is to'provide a novel construction which is of knock-downtype.l

Various additional objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings` illustrating an operative embodiment.

In said drawings Y Figurel is a planview of a runway constructed in accordance with my invention,

A modiied form of the invention is shown inFigures 5 and 6. The only diiii'erence is in the cap which here is designed 15L and is theequivalent of the cap 15. 4Such cap 15EL if` desired may be made of concrete and in its lower surface it may have a recessV 30 into which the upper lends ofthe piles extend. f In addition the caps 15a have slotsl'intoq v Y which thek shackles pass.

A further modified form isgshown in Fig-` ures 7 and 8 and the difference over the form of Figures 1 and Qresiding in jomitting'plates 18 so that theslabs 22'Vwill rest on the upper surface of beams 16.
