( Gerlingers 18-4) • The cable did not giveuniform action.(Master positive andRep. ). It is true that other straddle carriershad ropes or cable lifts and were probablynot as efficient as the Gerlinger device( Opin. Tr. 140). In addition to the patent taken out by Ross in De-cember 19, 1916, above referred to, Ross took out a sec-ond patent on straddle-type carriers issued July 9, 1918,No. 1,271,947 (Exh. 1-B Tr. 816). This patent again shows the use of cable-operatedload-lifting and lowering shoes. Next, William S. Overlin took out a patent on strad-dle-type carriers, dated December 31, 1918, No. 1,289,-529 (Exh. 1-C, Tr. 826), and Overlin obtained a furtherpatent on straddle-type carriers August 10, 1920, ,349,292, (Exh. 1-D Tr. 838). Both these Overlinpatents show the use of cable-operated load-lifting andlowering mechanism. Mr. Gerlinger, observing the inefficiency of the cable-operated load-lifting and lowering mechanism in strad-dle-type carrier, conceived his improvement. This con-sisted in eliminating the undependable, cable-operatedmechanism and providing in place thereof mechanismwhich operated positiv
