THE TILT BOX. 171 



The levers or cranks attached to the tilt box axles are 

 long, and the handwheels attached to the cylinder axles 

 are of considerable size, because the axles represented in 

 the cuts are each 145 ft. long. If the tilt box axle is of 

 wood, a wooden lever, Fig. 88, strengthened by iron 

 plates, may be fitted to one end of the axle, which is 

 squared, Fig. 70, #, and after the lever is put on, a 

 collar, a, keeps it in place.
