ALCOHOL-GAS BURNER.

To all whom it may concern:

Be it known that I, TVEsLEY E. OOOHRAN, citizen of the United States, residing at Montgomery, in the county of Montgomery and State of Alabama, have invented certain new and useful Improvements in Alcohol- Gas Rumors, of which the following is a specification.

The present invention provides a burner especially designed for heating sad irons and utilizing alcohol as fuel, the construction being such as to insure economy in consumption of the fuel and a thorough and effective heating of the irons.

The invention supplies a sad iron heater of the nature aforesaid which is light, easy of manipulation, adapted to be readily cleaned should occasion require, efficient in use, compact in construction and reliable in operation.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a central longitudinal section of a burner embodying the invention; Fig. 2 is a section on the line ww of Fig. 1; and Fig. 3 is a section on the line y-y of Fig. 1.

Corresponding and like parts are referred to in the followin description and indicated in all the views of the drawings by the same reference characters.

The device comprises a burner, a generator, a collecting chamber and a superheater.

The burner 1 consists of a tube having a series of perforations along its length forming outlets. One end of the tube is closed by means of a plug 2 and the opposite end is provided with a mixing chamber 3. The outer end of the opening formed in the mixing chamber is contracted and the inner end is enlarged and said mixing chamber is threaded or otherwise secured to the burner tube 1. A heat conducting tube 4 is arranged above the burner 1 and adj acentthereto and is secured to the burner tube, either by being brazed thereto or in any convenient and substantial way. One end of the heat conducting tube is closed by means of a plug 5 and its opposite end is connected to the generator 6 by means of a thimble 7 or other way.

Specification of Letters Patent. Application filed November 27, 1908.

iatented Feb. 8, 1910. Serial No. 464,564.

The generator 6 consists of a tube of approximately elbow form and is filled with wire gauze 8 or other material generally employed for retarding the flow of liquid fuel and distributing same to insure effective ac tion of heat thereon, whereby said liquid fuel is converted into vapor or gas. The outer end of the generator 6 is adapted to be connected to a reservoir or tank, not shown, in any manner, so as to supply the liquid fuel to the generator when the burner is in operation. The collecting chamber 9 projects vertically from the generator 6 and connects with the latter at a point between its ends. A cap 10 closes the upper end of the collecting chamber and is provided at a central point with a threaded opening to receive the threaded portion of a needle valve 11, the latter being provided at its outer end with a button or finger piece in the well known manner. A tube 12 is located centrally within the collecting chamber 9 and its upper end is adapted to be closed by the needle valve 11. The lower portion of the tube 12 extends across the generator 6 and beyond the lower side thereof and curves toward the burner and is pro vided with a nozzle 13 whose extremity enters the contracted end of the mixing chamber 3, so as to direct a jet of gas therethrough when the burner is in operation.

The burner l and heat conducting tube 4- are designed to occupy an approximately horizontal position, whereas the collecting chamber 9 extends vertically. The horizontal portion of the generator 6 is in line with the heat conducting tube 4 and rests upon the edge portion of the burner l to which it is attached.

The alcohol or other liquid fuel is supplied to the generator 6 in regulated quantity in the manner well understood and is converted into vapor or gas from the heat derived from the burner. The vapor or gas passes from the generator into the collecting chamber 9 and thence into the tube 12 and outward therefrom through the nozzle 13 into the burner 1 where it is consumed as it issues from the outlets in the side thereof. It is to be understood that a space exists between the nozzle 18 and the end of the mixing chamber 3 for the ingress of air, the jet of gas issuing from the nozzle 13 creating a vacuum in the mixing chamber resulting in drawing air into said chamber for admixture with the gas, so as to insure a perfect combustion and to produce an in-- tense heat. By having the heat-conducting tube 4 located directly above the burner I it is intensely heated and by the well known law of conduction and convection transmits the heat to the generator 6, so as to convert the liquid fuel into the form of vapor or gas, which'is utilized for producing the heat, said gas being consumed as it issues from the outlets in the side of the burner 1.

The burner is exceedingly simple and compact in ;construction, capable of being cheaplymanufactured and effective and re- -liab]ein operation and is also light in formation and adapted to be easily and effectively manipulated.

Having thus described the invention what isclaimed as new is:

l. A device of the character specified comprising a burner, a heat conducting tube adjacent to the burner and connected therewith, a generator having an end portion adjacent to the burner and connected with the heat conducting tube, a collecting chamber extending laterally from the generator and having its upper end closed, a tube housed within the collecting chamber and having its upper end provided with a valve seat and its lower end curved laterally and provided with a nozzle arranged to deliver a ct of gas into the burner, and a needle valve extending through the closed end of the collecting chamber and engaging said valve seat.

2. In combination a burner, a generator arranged within the heating zone of the burner a heat conducting tube connected with the generator and disposed above and in vertical alinement with said burner, a collecting chamber projected from the generator, a tube located within the collecting chamber and having its upper end open and spaced from the top of the collecting chamber and its lower end extending through the generator and provided with a lateral nozzle arranged to deliver gas into one end of the burner, and a valve extending within the open end of the tube for regulating the gas admitted to said tube.

3. In combination a burner, a generator having a portion arranged within the heating zone of the burner, a collecting chamber projected from the generator a cup forming a closure for the upper end of the collecting chamber, and having a threaded opening formed therein, a tube located within the collecting chamber and having its upper end open and its lower end extended through the generator, and provided with a nozzle arranged to deliver a jet of gas into the burner, and a needle valve threaded in the cup and adapted to enter the open end of the tube for controlling the passage of gas to the burner.

4-. In combination a burner provided at one end with a mixing chamber a heat-conducting tube adjacent to the burner, a generator having an end portion adjacent to the burner and connected to said heat conducting tube and having its outer end curved, a collecting chamber extended from the generator at a point between its ends, a tube located within the collecting chamber and extended through the generator and having its projecting end curved toward the burner and provided with a nozzle discharging into the said mixing chamber, and a valve to control the receiving end of the tube and fitted to the extremity of said collecting chamber.

In testimony whereof I aflix my signature in presence of two witnesses. WVESLEY E. COCI-IRAN. [11. s.]
