 secured by a head on one side of the tank and a split pin or nut 

 on the other, so that it can be easily withdrawn if it is necessary 

 to remove the agitator for cleaning. 



The 1 -in. rubber suction tube shown in Fig. 5 is .carried to a 

 strainer (Fig. 8) consisting of a 1 J-in. gas barrel flange, a nippier 

 plug, and reducing T i| in. to J in. To obtain a larger straining 

 area than the size of the suction tube, a wooden washer is placed 

 between the bottom of the cistern and the flange. A strainer

 attached to a piece of f-in gas barrel screwed into the T. 

 The plug is fitted to the T for flushing purposes. The pump

 the handle of the agitator (see Fig. 5) by a connecting rod, 

 made as in Fig. 7. The position of this rod must be found 

 by experiment. It is made 2 ft. long from hole to hole. It 

 should first be fixed to the pump handle, and then a gimlet 

 passed through the hole in the other end into the agitator handle, 

 until on the full stroke of the pump being made the agitator will 

 travel backwards and forwards in the tank without touching the
