 the heavy tools, such as boring mills, planers, and 

 large lathes, are in the main bay under the crane. 

 Usually the floor space at one end of the central 

 bay is used as an assembling floor. The heavy 

 pieces are brought lengthwise by the traveling 

 crane from the large tools to this floor, while 

 the lighter pieces come in from the galleries on 

 the side. Railway tracks run in onto the assem- 

 bling floor, so that the crane may be used for 

 placing the finished machinery on the cars for 

 shipment. In this way, all the material, large 

 and small, centers on the assembling floor and 

 may be shipped out without confusion. 



It will be seen that the aim in all these different 

 types of buildings is to design them so that they 

 will handle the material in the cheapest manner 

 and move it from the beginning of its course to
