The self-evident fact has been noted in this historical review thatlofty buildings are feasible oidy through the use of the elevatorAnother feature in making lofty buildings financiallv feasible was theuse of a new system of constructing fireproof arches between theiron floor beams. For years after the introduction of rolled beams,the method of filling in l)etween the iron floor beams was by meansof common brick arches leveled up on top with concrete, and flooredover. On the under side the bottom surfaces of the iron beams were. left exposed and painted A ceiling of a room, then, consistedof a series of arches between iron beams, altogether very unpleasantin ap]iearance. If a level ceiling was determined upon it had to beobtained by wood furrings and wood lathing fastened u]) to the un-derside of the beams and then ])lastered. thus greatly detractingfrom tile fire-resisting (|ualities: or b\ iron lath stretched from ])camto beam and ])laslered. The lieavy weight of the brick arches wasthus further increased l)y the w eiglit of tlie level ceiling arrangementunderneath. An American citizen, l\reischer, a well-known manufacturer of fire-brick in Xew ^ork cit\-, invented andpatented in 1871 the use of hollow-tile flat arches between iron floorbeams. His was not the invention of a flat arch in itself, but of aflat arch whose end sections abut against rolled iron floor beams andrecess aro
