MOTORS 



4716. MOTOR, Porter Battery No. 1. A standard article, perfect in every detail of design arid con- 



struction, and accurately made. Nicely finished in black enamel. 1/100 h. p., 1.5-3 volts, 1.5 

 amperes, 5500 r. p. m.; size, 3^x3 l /4,x3% inches; weight, 1% Ibs $4.00 



4717. MOTOR, Porter Battery No. 2. Same as No. 4716, but 1/90 h. p., 3-5 volts, 2 amperes, 4000 



r. p. m.; size, 3%x4x4% inches; weight, 2% Ibs 7.00 



4720. MOTOR, Universal. This motor may be used on 110 volt either Alternating (60 cycle) or Direct 

 Current. Will develop approximately 1/50 h. p., is efficient and will not heat up when oper- 

 ating on either circuit. It is constructed in a substantial manner, having laminated fields and 

 armature and a twelve-section copper commutator. It uses a ^g-inch carbon brush and is 

 equipped with compression grease cups and bronze bearings which insure perfect lubrication. 

 It weighs 4% pounds, is 5 inches high and consumes .about the same amount of current as one 

 8 candle power lamp 8.00 



4724. BATTERY RHEOSTAT, for regulating the speed of small motors, and also for use with minia- 

 ture battery lamps. This rheostat is nicely finished with nickel trimmings and rubber handle. 

 Resistance, to 5 ohms 1.40 



MOTORS, Alternating Current, Single Phase, 60 Cycle. These General Electric A. C. Power 

 Motors are of the Split Phase Induction Type for constant speed and continuous service.
