AN AUTOMATIC CIRCULATOR 



(Patent Applied for) 



Something which works while you sleep. No anxiety as to whether the power for forced circulation is on or off. Should 

 anything happen to the power, putting your forced circulation out of commission, this new device, not dependent upon anything except 

 nature's laws, takes up its task automatically. 



ABSOLUTELY AUTOMATIC 



and it knocks everything else In forced circulation silly. Made with single, double or multiple propellors as our customers 

 desire. After three years' experience we know we have the best apparatus ever built, equally as efficient as the original Electric 

 Circulator or its copies in operation, simpler by far in construction, cheaper in price and any one who can make up two 

 Hanged joints and attach a belt can install it. 



It is a 'winner. Drop a line to us and we -will be glad to show you. 



We have a new coupling for pipe or boiler tubes which is worth looking up. We hope very soon to show steam men something 

 for returning wattr of condensation and automatically producing a vacuum. We are still placing the Castle Boiler and ready to 

 accept orders for best modern piping systems. Hot Water or Steam.
