of the frame and the adjustable pipes are 

 spaced so that the empty shells fall through. 

 Except for large objects such as conchs and 

 occasional flotsam, the scallops and all other 

 material thus separated go through the 

 shucker. An improved model is a 2-way separa- 

 tor with an extension to the lower end of the 

 frame with the pipe spacings widened to permit 

 live scallops to pass through, while larger ob- 

 jects continue in another direction. Another 

 simplified version, utilizing the same general 



principle, has a series of spaced pipes built into 

 an inclined rotating cylinder called a "squirrel 

 cage" that sorts out shells and debris. When 

 equipped with cleansing seawater spray and 

 made to function as a screw-type conveyor, this 

 version has proved best (figs. 17 and 18).
