APPARATUS FOR CAR 'BUBETING AIR.

Specification of Letters Patent.

Application filed April 12, 1906.

Patented. Dec. s, 1908.

Serial No. 311,299.

To all whom it may concern:

. Be it known that I, SEYMOUR 'W. PERE- GRINE, a citizen of the United States, residing at Portland, Maine, have invented cer tain new and useful Improvements in Apparatus for Carbureting Air, of which the following is a specification My invention relates to a carbureting system for use in making gas, for supplying dwelling-houses with light and fuel, and for;

other like purposes, and it concerns more particularly means for supplying heated air under pressure to the carbureting chamber to facilitate the production of the gas.

The invention consists in the features and combination and arrangement of parts hereinafter described and particularly pointed out in the claim.

The drawing represents the apparatus in connection with a portion of a building, the wall of which is shown in section.

In this drawing, 1 indicates the wall of the building, 2 the first floor thereof, and- 3 the basement or cellar.

The carbureting chamber for purposes of safety is arranged outside of the building em bedded in the ground at a certain distance below the surface thereof. This chamber is indicated at 4 and as my invention does not concern the detailed construction thereof, it is merely shown in outline. The filling tube for this carbureting chamber is shown at 5 extending therefrom to the ground level. Air under pressure is supplied to the carbureting chamber through the pipe 6 and the gas or carbureted air is conducted from the chamber through the pipe 7, this pipe extending into the building and forming the distributing house main.

The apparatus for placing the air under pressure and for heating the same is arranged within the building, and in the basement thereof, and in providing this apparatus 1 have in mind the necessity to provide such an arrangement as will be entirely safe in use against explosion. With this end in view the air pipe connects with a heating box 8 which is located at a point near the top of the cellar, the point of connection 9 between the air pipe and the heating box or chamber being considerably above the level of the top of the fill pipe 5. Air is supplied to the chamber 8 through a pipe 9 connected therewith at its lower portion, the said pipe extending from an aerometer 10 of any well known construction. This aerometer in turn is connected bythe pipe 11 with an air compressing pump 12 of any suitable design. The chamber 8 is not heated by a direct flame, but on the contrary I avoid the use of a flame at this point and use instead a heating C011 13 arranged within the box or chamber and connected by the pipes 14, 15, with the heating apparatus of the building. This may be a steam heater, a hot water heater or a hot air heater with pipes 14, 15 coiled in fire box. The air is discharged from the pipe 9 into the space within the heating chamber or box 8, and coming in contact with the hot water or steam coil is heated and passes under pressure through the pipe 6 to the carburetmg chamber 4.

By reason of the location of the heating chamber and the end 9 of the air su ply pipe at a point above the level of the f1 1 pipe, it will be noticed that there will be no danger of the oil passing back through the air supply pipe when the tank 4 is being filled and because of the use of the heating coil the hability of explosion is removed, for even should leakage occur, gas would not come in contact with a flame at this point. It will be further noticed that the air does not have to pass through a heating coil on its way to the chamber'4, but it passes into a chamber 8 at one end and out of the chamber at the other end, it contacting with a heated coil during its passage through this chamber. This is an important feature, as to pass the air through a coil causes back pressure and requires more power and is therefore not so easily controlled to give a steady light.

When the heating apparatus of the building is out of service for instance in summer, the heat for raising the temperature of-the air may be supplied through an auxiliary heating device located in a room separate from that of the basement or at such a point where all danger of the flame coming in contact with any gas will be avoided. Such a heating device 1 indicate generally at 16, this being a gas heater, the flame of which is applied to a coil 17 connected through pipe 18 with'the pipe 14 and by means of the pipe 19 with pipe 15. Suitable valves are provided at 20, 21, 22 and 23 to provide for the use of either the main heating apparatus or the auxiliary apparatus.

From the above it will be seen that I so arrange the parts that there will be no danger I claim as my invention: In a carbureting plant for supplying of oil entering the building when the carbuildings, the combination of a carbureting 25 bureter is filled and no danger of the gas coming in contact with the flame, and further the air under pressure may pass freely through its heater and to the carbureting chamber with a minimum expenditure of power.

In connection With the air heater, I employ a thermostat to control the temperature at which the air shall be heated. This thermostat is indicated at 24 generally, and it controls the steam or hot water valve 25. The thermostat may be of any suitable construction.

It will be observed that the aerometer controls the inlet pipe leading to the system for the supply of air, the said aerometer being connected with a valve in the air inlet pipe to open or close the said valve according as the pressure in the system decreases or increases.

. tank outside the building, an air heating tank Within the building independent of the carbureter and elevated in respect to the outside tank, an air pipe leading to said elevated chamber, an aerometer connected with .said pipe controlling automatically the pressure therein, a'heating coil within the tank, and a thermostat connected with the interior of the tank controlling the heating effect of said coil, whereby both the pressure and the temperature of the air supplied to the carbureter is automatically controlled, substantially as described.

In testimony whereof, I afliX my signature in presence of two witnesses.
