WILSON: COLLECTING MACHINE 



287 



The main box is made of galvanized iron and is 4 feet long, 2 feet 

 high and 18 inches wide, the bottom piece being of one continuous 

 piece soldered and riveted at the corners. This lessens the danger of 

 melting the soldered connections. In the present case the box is 

 braced with pieces of iron bed rails riveted around the bottom and 

 along the corners, with a continuous band around the top; the band 

 is of iron 1 inch x 3-16 inch. This makes a strong but light box and 

 one person can handle it without much trouble. 



The end E is made in two parts, the upper part being fastened to 

 the lower with hinges, so that it can be lowered and ready access

gained to the two lower trays. The water tank is of galvanized iron 

 and is made in the form of an inverted tray soldered to the inside of 

 the tank. This tray is two inches deep with an inlet hole in one 

 corner and an iron tube connected to the outside whereby the steam 

 is carried away. 



At the end E a crank and sprocket wheels with a bicycle chain can 

 be used to jar the trays by raising them and dropping them. At the 

 bottom of the middle tray a round wooden piece with a 'raised side 

 is run across the box and at every revolution of this piece the tray 

 is raised and allowed to drop. The other two trays are fastened to 

 this one and are raised and dropped at the same time, giving all of 

 them a steady but light jar. 



The top tray is made so that the ends and sides are parellel with 

 the top and with the sides slanting inward so that the bottom of the 

 tray is smaller than the top of the tray below. A piece is morticed 

 in to the end and is allowed to drop about 11 inches below the end 

 of the tray at the end E. From the other end of the tray another
