Kimley Electro- 

 Analysis 

 Apparatus 



for the rapid determhiation of 



Copper, Ti7i, Lead 



Zinc, etc. 



The stand is composed of three circular 

 castings mounted on an aluminum pipe, 

 so as to permit the stand to be turned 

 nearly 180° in either direction. 



The upper circular casting carries 6 re- 

 sistance lamps. Each lamp has in series 

 with it a push button switch, also 

 mounted on this same casting. 



The center circular casting carries the 

 electrode holders, a push botton switch 

 to short circuit the electrode holders 

 when not in use, and a pole-reversing 

 switch to change the polarity of the elec- 

 trodes. Each lamp on the upper casting 

 is in parallel with the electrodes under it 

 ■m the center casting so as to take up the 

 current carried by the solution when the 

 solution is lowered, so that the electrodes 

 are out of contact with it. A motor for 

 revolving the electrodes is mounted on 

 _,^« the center support, between 



"^^S^ *'^^ ^^'^ UPPS'' castings. The 

 1^^^/^^ lower circular casting serves 

 ^^^^^ mly to carry the supports 

 !'or the beakers.
