702,489. Overhead railways. AMERICAN MONO RAIL CO. Aug. 30,1951, No. 20187/51. Classes 104 (2) and 104 (3) [Also in Group XXXVI] In a track for a suspended conveyer the conveyer-wheels 18 collect current from spaced apart rails 2 supported and insulated from each other at spaced intervals by electrical insulation members and clips 3 connect each rail separately to the member 1 so that the rails can be assembled and dismantled independently of each other. The metal rails 2 are supported in slots 7 in the insulating members 1 by horizontal flanges 13 held therein by metal clips 3. The current is fed to the rails 2 by leads 20, 21. In constructions for carrying light loads the members 1, wholly of an insulating material are suspended by hanger rods screwed into the top thereof. In constructions for carrying heavy loads the members 1 are as shown in Fig. 5, of metal 30 coated with rubber 31 or a similar insulating material. The rails 2 are shielded by a U-shaped member 25 extending to the lower edges thereof.
