Original elevator trade vintage catalog for THE PATERSON-LEITHCH COMPANY, was located in Cleveland, OH. Manufacturers of Steelite freight elevator gates, designed by elevator men to meet the need for an up-to-date protection for freight elevator hatchways. Both the gate and all of the equipment used in connection with it are made entirely of metal. Disbound from a large 1916 elevator construction materials book, this unique old one page technical brochure would display wonderfully matted and framed. A marvelous addition to your retro elevator equipment library. Contains a small amount of residual glue on edge.
