' Application fla'au ust 1 2, 1912. Serial No. 714,604.

, ing at Chicago, in the county'of Cook and State of Illinois, have invented'eertain new and useful Improvements in Vaporizers, of

which the following is a specification. I

The present invention relates toimprove ments in Vaporizers, and is, designed for use in connection with. gas operated engines of varioustypes.

The object of the invention is the provision of a vaporizer, attached, preferably to theexhaust pipe or tube of a gas engine and receiving heat therefrom to vaporize the crude, -or. other oil, fed to the vaporizer.-

In the practical application of my device for actual use in connection with the exhaust pipefrom the engine, I utilize means for regulating the flow of oil to the vaporizer where it is vaporized by the heat from the exhaust pipe in connection with-other mechanical means, and-.1 provide further improved and novel features as .willbg evident from the following specific'ation taken in connection with. the drawings.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles.

Figure 1 is a vertical, longitudinal sec Fig. 2 is a transverse sectional view of the vaporizer. Fig. 3 is'a bottom plan view of the oil spray or nozzle. Fig. 4 is a vertical longitudinal sectional View of the oil spray or nozzle.

In the preferred embodiment of m invention I employ the casing 1 which orms a cylindrical chamber with closed ends, about the exhaust pipe 2, a portion of which is illustrated in the drawings and through which the exhaust from the engine passes, the gases of combustion serving to heat the :interior of the chamber to atemperature sufliciently high in order that crude or other oil may be vaporized therein.

Within the casing and directly surroundingin close proximity the pipe 1 is located a. wire gauze or screen 3 of foraminous material, while three other screens 4, o, and 6 are located in the chamber adjacent the interior walls of the cylindrical casing. The screen 3 is for the infiowing oil and the screens 4 5, and 6, are for the purpose of filtering t eoutgoing gases.

Crude oil is fed, to the vaporizing cha nber-from a suit-ably located oil tank (not shown,) through the oil feed pipe 7. In

Fig; 1 it will be seen that the oil feed pipe 7 is" provided with a return'bend 10" inside the casing or drum and a spraying nozzle 11 is interposed in the pipe. This nozzle is formed with a depending perforated cap 12 through which the oilis fed to the foraminous screen 3. The return bend 10 permits the oil to become heated in its passage 'through the drum before reaching the spray, and in this manner the vaporiza':

tion of the oil [is aidedby a preliminary heating A plurality of'air'valves, as 18, areprovided in the drum 1 as air inlets to furnish 5 fuel air -for;-'mixing"with the gases in the drum and-these valves are actuated by Suetion from the engine'as usual.

- The vapor or gas, w1th the air mingled" therewith passes through the filtering screens 4,, 5, and 6' into the gas or fuel supply p'pe 14 which is provided with'z'the usual regulating valve.

In Figv 1 an auxiliary gasolene supply.

tank is illustrated at 19 adapted to supply fuel through valve 20 to the fuel supply pipe. This supply is for use in starting the engine, as it will of course be understood that the vaporizer illustrated willnot com 7 The operation of the device is obvious..-

Crude or. other oil is fed through the oil pipe from a supply tank, into the return bend in the drum. In its passage through the bend the oil is given a preliminary heating, and as it is sprayed through the per forated cap of the nozzle, the heat from the gases of combustion in the exhaust pipe vaporizes the oil. Air is admitted to the mence to vaporize the inflowing oil until the e" 1. The combination with a heating mem ber Qf a drum surrounding the same and provided with closed ends, an oil inlet pipe to the drum, a foraminous screen surrounding said member for distribution of oil, and

a similar screen adjacent the Walls of the drum forming a s ace for filtered gas to pass to the outlet or the drum.

2'. A vaporizer comprising a heatin member, adrum incasing said member an provided with oil inlet and gas outlet, a

foraminous screen surrounding the heating member for distribution of oil, and a series memes the drum for filtering vapor in its passage to the outlet.

3. The combination with a vaporizing drum having an oil inlet pipe passing therethrough with a return bend and provided with a spray nozzle, of a heating member within the drum, a foramino'us screen inclosing said member for distribution of oil, and a series of screens adjacent the walls of the drum forming a filtered gas space provided with a gas outlet.

In testimony whereof I aifix my signature in presence of two Witnesses.
