GAS-GENERATING APPARATUS.

Specification of Letters Patent.

Application filed May 7, 1910.

Patented July 18, 1911.

Serial No. 559,869.

To all whom it may cancer/1.:

Be it known that I, JAMEs M. ONEALL, a citizen of the United States, residing at Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Gas-Generating Apparatus, of which the following is a specification.

This invention has relation to gas generators.

The object of the invention is to provide a suitable apparatus for generating a combustible gas which is produced by saturating a fluid forced downward through the apparatus, with certain elements, which the fluid encounters. w

A further object is to provide a generating vessel comprising a plurality of chambers or compartments having restrained commu nication, distributing cups in some of the compartments; a supply reservoir; means for producing an equal air pressure above and below the contents of the reservoir and also forcing air through the various compartments of the vessel; and various other details of construction which will be hereinafter set forth.

Finally the object of the invention is to provide means of the character described that will be strong, durable, efficient, and easy of operation, simple and comparatively inexpensive to construct, and also in which the several parts will not be likely to get out of working order.

With the above and other'objects in view, the invention has relation to certain novel features of construction and operation, an example of which is described in this specification and illustrated in the accompanying drawings, wherein:

Figure 1. is a vertical sectional view of the apparatus with portions of the pipe connec tions inelevation, Fig. 2. is a horizontal sectional view on the line SD of Fig. 1, Fig. 3. is a view similar to Fig. 1 with the wicks and metal filling omitted, and Fig. 4. is an elevation of the apparatus.

In the drawings the numeral 1, designates a vertical cylindrical vesselhavingadischarge pipe 2 leading from its side near its lower end, and a supply or feed pipe 3 entering its top and supported therefrom. At its upper end, the pipe 3 enters the bottom of a reser voir 4 which has communication at its upper end with. a pipe 5 extending from an air pump 6. By means of this pump air is forced through the pipe 5 past a suitable check valve 7 which prevents back pressure. It is to be understood that while I have shown a hand pump, a power operating pump may be employed. From the pipe 5, a branch pipe 8 leads to the supply pipe 3. Between the branch pipe and the bottom of the reservoir, a suitable regulating or feed valve 9 is connected in the supply pipe. It is obvious that the pressure of the air delivered into the upper portion of the reservoir will be substantially the same as the pressure of the air passing through the branch pipe 8 to the supply pipe 3. Thus the pressure above and below the contents of the reservoir will be substantially equal thereby permitting a gravity feed into the supply pipe regulated by the valve 9.

In the reservoir 4- which has a suitable opening in its top, an acid or an acidulous fluid, such as common vinegar, or salt, such as common salt, and volatile oil, such as gasolene, may be placed. Acids and hydro carbon oils may be introduced into the reservoir as well as iron filings if desired.

The vessel 1 is divided into a plurality of horizontal chambers by cross partitions 10, each receiving the hollow stem 12 of a cup 11, the cups resting on the partitions and the stems passing through the partitions and terminating a short distance below the same. Beginning with the upper cup, each alternate one is disposed substantially at the center of the partition, while the intermediate cups are ofl"center or eccentric, but not to such an extent that the stem of one cup will not deliver into the cup below. This arrangement places the cups in staggered relation vertically, but each with a portion substantially in vertical alinement with the supply pipe 3.

In each compartment a filling of metal 14: such as iron or steel, is placed. This metal should be such as will readily rust and may be in such form or shape as is suitable. Iron 01' steel filings mixed with small pieces of scrap have been used with good results. The cups are filled with suitable strands of fiber, cotton wicking, or Waste 15, which extends from the cups and is interspersed in the metal filling, that is the strands are separated and mixed in with the particles and pieces of the metal filling.

The process of capillary attraction is employed, or in other words the mixture delivered from the supply pipe 3 to the upper- REISSUEE most cup, and from it to the others, is distributed or spread into the metal filling by the fibrous material 12, the st ands of the fibrous material being saturated by the process of capillary attraction.

It will be noted that there is no cup in the lowermost chamber of the vessel and it is intended that only enough of the mixture should enter this chamber to thoroughly cover the metal filling without any surplus or overflow. The object of the cups is to catch or retain the mixture passing from one chamber to the next lowermost one and the supply will decrease as it passes downward. Of course sufficient amounts of the mixture must be supplied to the cups to saturate the fibrous strands, the surplus from each cup passing through the stem 12 to the next lowest cup.

Each partition is provided with a pair of openings 16, the openings of one partition being out of line with those of the adjacent partition, as indicated in Fig. 2. The cups are filled with the fibrous material to such an extent that light fluids such as gas and air cannot pass therethrough and must pursue a circuitous path through the chambers and their filling by passing through the openings 16.

The mixture hereinbefore described is calculated to rust the metal fillings. Acid and salt and such materials as produce rust from iron when introduced into the receptacle 1 produce gas. The metal or iron filings when subjected to these materials produces rust and heat. The oils are converted into gas and mix with the fumes and rust. The current of air forced into the vessel has only sutlicientpressure to cause it to How downward and become saturated with the mixture, laden with which it passes outof the vessel through the pipe 2.

Much stress is laid on the fact that the mixture is fed to the vessel by gravity and the air is passed through or over the gas .producing mixture with only enough pressure to cause it to flow in its proper course. It is one of the objects of this invention to produce gas without a high air pressure and With only a flowing pressure.

The fumes produced by mixing the acid, filings and salt after the acid and salt has been. introduced into the receptacle 1, rise. The hydrogen thus generated is carbureted by means of the vapors of hydrocarbon oil and the air which is forced into the vessel. This mixture of various elements produces a commercial gas.

Tests have shown that this gas produces an intense heat and when burned, gives a soft mellow light. It is inexpensive to pro duce and having a low pressure its liability to explode is reduced to a minimum.

For indicating the pressure of the air in the upper portion of the Vessel 1, a suitable gage 18 is placed thereon. If the quantity of the mixture fed to the uppermost chanrber accumulates too fast therein it can be, relieved, and a portion quickly conveyed to the next lowermost chamber by means of a bleeder pipe 20 at the side of the vessel. in which pipe a cut-off valve 22 is included.

It is pointed out that it is possible to gen erate gas in each chamber of the vessel. However the gas becomes richer as it emerges from each chamber and a better gas is produced by passing the air through the several chambers and thoroughly saturating it with the gas producing elements.
