Drinking 

 Fountain 



Safety First! Install a Bubble Foun- 

 tain in Your Home 



BELIEVING it to be unsafe for two 

 persons to use the same cup, even in

 ton, D. C, devised a bubble fountain to 

 be combined with the sink faucet. 



To drink from this fountain, you simply 

 turn a horizontal lever 

 to the left. This turns 

 a two-way valve. One 

 part of the valve ro- 

 tates into position to 

 connect the supply-

 and you take your 

 drink as the water bub-

When you turn the 

 handle-shaped lever at

 allowed to run out at 

 the faucet for use in

 end collisions, worry him not. 



The only expense connected with the 

 maintenance of the one-ox line is the feed 

 necessary to keep the animal going. 

 Once you get its machinery in motion, 

 you can forget about it, which is more 

 than any automobile 

 owner can say.
