Electric Cars in Paris.—An electric car is now in actual ser-vice in Paris, on the tramway running through the Avenue dela Grande-Armce. Power is furnished by a battery of 144 ac-cumulators of the Faure-Sellon-Volckmar type, and the usualservice is about hours without recharging. The motor is ofthe Siemens type, and is carried on the front platform, ihe con-nection with the driving-axle being made by chain-belts, ar-ranged as shown in the accompanying sketch. The motor runsat from 1,000 to 1,200 revolutions per minute ; from the motor. shaft j1/the belt runs to the large pulley on the intermediateshaft P. This shaft carries two small pulleys, from which twochain belts, G, run over two pulleys, C, on the driving axle. Thedriving-wheels revolve independently of each other, and can berun at different speeds in passing around weight of this car is about as follows : Car lbs. Accumulators 3,300 * Motor, pulleys, etc 1,650 ** Passengers (full load) 7-700 Total 20,350 lbs. The car has, like most of the Paris tram-cars, seats on theroof, and can carry 50 passengers when fully loaded.
