FROM THE PRACTICAL VIEWPOINT 



installed two or three jets of water for rinsing cans, 

 and also three or more jets of steam. Each jet 

 should be provided with an automatic valve which 

 will be opened by the weight or pressure of the 

 can as it is placed over the jet. If flanges of iron 

 or sections of gas pipe are so attached to the table 

 that they will engage the flare of the can mouth 

 as it is inverted over the table, it will be impos- 

 sible to remove the can until it has travelled entire 

 length of the table and has thus received the 

 influx of water and steam from each of the jets. 

 It is possible to so arrange the table that both 

 cans and covers will be treated at the same time on 

 the same table. This is accomplished by install- 

 ing two sets of gas-pipe guides, one of them to 

 hold the cans in place and the other of them to be 

 just above the covers as they are pushed along the 

 table, with the open end down. The cans referred 

 to in this connection are the standard forty-quart 

 cans used most largely in the East. 



Various machines are on the market which are 

 so arranged that the cans, after having been well 

 steamed, are also dried by means of a blast of 

 heated air. This drying is important for two 

 reasons. First, because the moisture which may
