As there has been a considerable demand for enamelled resistanceunits so arranged that they can be conveniently mounted uponpanels, switchboards, etc., being so designed that they are readilyinterchangeable, the Ward Leonard Electric Company, of Bronx-ville, New York, has designed and perfected the method of mounting. INTERCH.\NGE.\BLE shown in the cut. The cut shows B size unit, but any of its differentsized tubes can be arranged in the same manner. The tubes can betaken from the bases by hand without use of any tools—just asreadily as panel cartridge fuses are removed. Different units ofgreater or lesser resistance can be used to replace each other and anydesired result may be obtained. The Ward Leonard Company has soldover 2,000,000 of its enamelled resistance tubes (having the resistancewire hermetically sealed from the atmosphere) during the last fouryears, and its engineers, are busy daily accommodating the tradewith various improved methods of mounting these devices. Truing Commutators. How best and easiest to true up commutators is always a problemfor the manager of a plant, and it is universally recognized that themost desirable and proper way is to do it without removing the
