AIR AND GAS MIXER.

SPECIFICATION forming part of Letters Patent No. 741,809, dated October 20, 1903.

Application filed December 12, 1902. Serial No- 135,025. (No model.)

To all whom it may concern: Be it known that I, FRANK J. MOEHN, a citizen of the UnitedStates, residing at Colorado Springs, in the county of El Paso and State of Colorado, have invented certain new and useful Improvements in Carburetors; and I do declare the following to be a full, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

My invention relates to a-gas-generating apparatus of the air-carbureter type.

The object of my invention is to provide a mixing chamber for carhureters that will thoroughly mix atmospheric air with hydrocarbon vapor to make illuminating-gas.

The foregoing object is attained by the construction illustrated in the drawings, in which Figure 1 is a vertical central cross-section of the gas-mixer and gas-tank, and Figs. 2 and 3 are detail views of the two styles of disks employed in the mixing-chamber.

0 represents a gas-storage tank, which is preferably placed within the building or adj acent thereto. It is connected with asnitable carbureter by means of the gas-pipe, (represented by 0'.) The gas-pipe forming a conductor for the gas-vapor from the carburetor to the gas-tank O is passed upward through the bottom of the said tank and secured by means of proper threads and nuts in an airtight manner. It has its outlet into the mixerdrum, (indicated by D.) This mixer is composed of the drum and a series of disks, (indicated by D and D each alternate disk being perforated and extending the entire diameter of the mixer-drum D. The perforated disks D are represented fully by Fig. 5. The other disks, D are of smaller diameter and void of perforations, as shown in Fig. 6 of the drawings. All the disks are mounted upon a suitable rod secured within the said mixer-drum D, the rod passing through central apertures provided in the said disks. The storage-tank O is constructed in the ordinary telescopic manner of two parts, the upper part being in the form of a drum and kept in the proper plane by means of the rollerbearings (indicated by 0 operating against a suitable loop contriv'ance constructed of an iron rod and represented by C in diiferent figures of the drawings. The lower section of the telescopic tank is filled with water to the desired height. The outlet gas-pipe is represented by C and provides means for conducting the luminous gas from the gastank 0 to the gas-pipe leading to the burners or desired place of consumption.

The operation of my invention will be understood to be as follows: Air is forced through a suitable carbureter and takes up the vapor from hydrocarbon contained therein, thus becoming a gas heavily charged with hydrocarbon vapor. The gas is then forced through the gas-pipe G into the mixer-drum D, which is provided within the gas-tank O. A sufficient quantity of dry air is forced into the said mixer-drum D through the pipe 0 leading from a suitable airpump. (Not shown.) The mixing is done within the drum D and facilitated by means of the disks D and D The now-highly-hydrocarbonated gas passes upward through apertures provided in the top of the mixer-drum D and remains within the storage-tank 0 above the line of the water which is contained in the lower part of the tank until it is conveyed outward for consumption through the gaspipe 0 Which passes upward through the water contained in the lower part of the tank. The gas passes inward through the check-valve C and the air passes outward through the check-valve B These'valves are provided, as hereinbefore referred to, to prevent the gas from being forced backward and to prevent a backward current of air, which might prove dangerous in the case of fire or in the event that either of the pipes should become broken or injured in any manner.

Having thus described the nature and objects of my invention, with the manner of constructing and applying the same, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. An air and gas mixer comprising a chamber with outlets at its top, a vertical rod mounted in said chamber, and disks secured to said rod, each alternate disk fitting the inside of the chamber and provided with a number of perforations, and the other disks being imperforate and smaller than said alternate disks, substantially as shown and described.

2. An air and gas mixer comprising a cylindrical drum withoutlets at its top, a vertical rod mounted in said chamber, and circular disks secured to and spaced apart on said rod, each alternate disk fitting the inside of the drum and provided with a number of perforations, and the other disks being imperforate and smaller in diameter than said alternate disks, substantially as shown and described.

A chamber for mixing air and hydrocarbon vapor and storing it consisting of a telescoping tank, a cylindrical drum contained in said chamber having outlets at its top, a rod FRANK J. MOEHN.
