two toward the rear. Communication between passengers 

 and driver was by voice tube. Glass windows in the two 

 doors can be raised and lowered. Leather-covered fenders 

 shield the four wheels of the vehicle. Electric side lights, 

 operated from the batteries, are provided. 



Projecting beyond the passenger portion of the body, at 

 the front and at the rear, are two large compartments for 

 storage batteries. The rear compartment contains three 

 sets of 12 cells each, while the front contains one set, 48 

 cells altogether. The wiring from cell to cell is no longer 

 in place, and so the exact system used is not now known. 



Above the rear battery compartment, 7 feet above 

 ground, is the exposed seat for the driver and the footman. 

 On the left a steering tiller is attached to the upper end of 

 a long, vertically mounted shaft, which at its lower end is 

 connected by a long rod to the left steering knuckle. In 

 front of the driver is a combined 150-volt voltmeter and 

 ammeter, which indicated the state of charge and the rate 

 of charge and discharge of the batteries. On the left is a 

 lever that controls a horizontal drum type of controller 

 under the driver's seat. This governed the speed and 

 reversed the vehicle. 



External contracting brake bands on the two rear-wheel 

 brake drums are operated by a pedal pivoted in the floor- 

 board. 



A 5-horsepower motor-generator set in the garage of the 

 vehicle was used for overnight charging of the batteries. 

 This set (USNM 310471) was received with the vehicle 

 and appears to be contemporary with it. Both the motor 

 and generator were made by the Wagner Electric Manu- 

 facturing Co., of St. Louis, Mo. The motor is a 5-horse- 

 power, 208-volt, single-phase a.c, 60-cycle unit, while the 

 generator is a 125-volt d.c. unit capable of charging at a 

 rate of 28 ampere hours at 1,800 revolutions per minute. 

 A Weston voltmeter, Weston ammeter, circuit breakers, 

 fuses, switches, a rheostat, and variable resistance complete 

 the charging equipment.
