incubator. The shortness of the outlet and its slip-joint allow the 

 pan to be easily removed for cleaning or inspection; while the pro-

 into a sedimenting chamber to remove the solids derived from the 

 ice. This arrangement is to protect the drainage system from 

 clogging and to facilitate cleaning in case clogging should occur.
