out passing any hydrocarbons tln-ougli tlie pipes to whicli the burners 

 are attaclied, air alone being- all that is required. 



This invention has been recently secured to Mr. Clough by three 

 patents. 



The follov^ing is a general description of the burner : 



a represents the pipe to which the burner is attached; d the receptacle for holding the oil; c the 

 valve through which the oil is poured; /air-pipe; gg luhe-B, containing each a Vi'ick; p screw for 

 regulating the wicks ; n is an ordinary bat-wing gas-burner ; g represents the flame. 



Common air is forced through the pipe by means of aii}^ of :tlie 

 gasometers no^v in common use, at a pressure for a full light of about 

 one and a half inches. 



The volume of air required to support the flame is about four cubic 

 feet for a flame equaling that of a five feet gas burner, witJi good 

 coal gas. The greatest diameter of the oil-receptacle is four and a 

 half inches, and its height four inches ; holding, when fully charged, 

 about a pint and a half of oil, which will furnish a full flame twelve 

 hours, at a cost of seven and a half cents, the present cost of oil 

 being forty cents per gallon. 



The flame may be regulated with the same facility as that of coal 

 gas, forming a small light, or a large spread of flame, as convenience 

 may require. 



Where pipes are in dwellings or factories, the only expense for 

 introducing Mr. Clough's invention, is simply that of the burners. 



In factories where difficulty has been experienced in manufacturing 

 a regular supply of gas, the burner has simply to be attached to the 

 pipes, air pumped into the gasometer, and no disappointment will 

 occur from a failure to obtain a fine gas-light.
