COUNTERSHAFT *4 inch in diameter and 12 inches long, with bearings and pulleys 1, 2, 3 and 

 4 inches in diameter. The pulleys are bored and grooves turned true with the shaft, to which 

 they are fastened with set screws, so that their position on the shaft may be changed. Used in 

 connecting small engines and motors with other machinery 2.40 



SPEED REDUCING GEAR. An improved device by which the high speed of an engine or motor 

 is converted into a slow, powerful motion. The round plate may be removed, if desired, and 

 direct connection made to shaft. Geared 48 to 1. Pulleys grooved for %.>-inch round belt. The 

 fast running pulley has diameters 2, 3 and 4 inches, and the slow running pulley diameters 

 2 and 4 inches, thus giving a wide range of speeds 7.20 



SPEED REDUCING GEAR. Similar to No. 4814, but with the gear enclosed in a case which la 

 filled with grease so that the gear will run silently and without attention for a long time. 

 Geared 48 to 1. Pulleys grooved for % 2 -inch round belt. The fast running pulley is 4 inches 

 in diameter and the slow running pulley has diameters 1, 1%, 2 and 2% inches, thus giving a 

 wide range of speed 10.80
