Improved Type of Car Heater The latest and improved type of American Electric Corpora-tion panel heater, which is manufactured and sold by the SimplexElectrical Company, of Boston, is illustrated herewith. The viewexposes the details of construction, which are as follows:. 12-IN. SCALE KELVIN MOVING COIL VOLT METER The case is the conventional one of cast iron, bronze finish,as are all the cases of the different types of heaters. The electricheater consists, as shown, of two coils of special non-corrosivewire that is not affected by high temperature, moisture or acidfumes, and consequently, is practically indestructible. These coils the length of the coils, preventing the possibility of a coil gettingout of place, and maintaining it in place without tension on thecoil. Connected to the coils by good mechanical joints and soldered,are rubber covered, flexible, terminal conductors, which passthrough porcelain bushed holes (F) on the outside of the form of heater is used in all the different types of the coilspring car heaters, of which the company makes eight differentsizes and styles. As indicated in the engraving, this heater is ofgreat simplicity in construction and it is claimed by the makersthat any part, except the case, can be replaced fr
