0 /YDVBRT1S1NG SECTION FEBRUARY, I935 Enduring Finish withstands hard knocks at busy fountains After ADOPTING Bakelite Molded for their newKnight SodaFountains, The Bastian-Blessing Co. says of this material.. covers made from it withstand hardest knocks at busy fountains.... it is a superior heat insulator". Ice cream cabinet covers, cold storage compartment covers, draft arm handles and nozzles, and syrup pump covers are subjected to fre quent and often hurried handling. Through the use of Bakelite Molded these parts are given a permanently lustrous jet black finish and endur ing strength that defy hard service even at the hands of the heartiest "soda jerker". Heat protection is provided by the excellent thermal in sulation properties of this material. Each part is molded accurately to close dimensions in a single closing of the molding press. In the large covers, for example, the threaded metal inserts for the metal knobs, as well as for the full-length piano hingeB, are firmly embedded during the molding operation. There are many products that could be improved and simplified through the use of Bakelite Mate rials. We shall be glad to have you consult us and write for illustrated Booklet 3ZM, "Bakelite Molded". It shows many of the latest applica tions of Bakelite Molded and may suggest possibilities for your use. * At the left are shown an oval ice cream cabinet cover and a rectangular cold storage compartment cover, two of many Bakelite Molded parts in the Knight Soda Fountain made by the Bastian-Blessing Co., Chicago, IlL Other parts above are draft arm handle and noale, syrup pump cover and ladle cover.
