1 My invention relates to what I call a burner gun as a short name describing mechanisms and methods of operation which isadaptable to be used in a variety of ways for acting upon various materials for producing products which result from mixing, heating and smelting a number of difierent materials for qualities of various materials.

I succeed in doing a variety of work withmy mechanism herein shown and described without material changes of the mechanisms which I employ.

As a preliminary explanation of my invention by its use I may take powdered or granulated iron,

ore with which there has been mechanically mixed powdered coke or coal, and pass this materialthrough my mechanisms wherein there takes place combustions of fuel in liquid or gaseous producing special 2 Claims. (Cl. 263- 29) form into a stream of the above mentioned powdered material carried by a blast of air into a furnace chamber whereby there then takes place the result of progressively smelting the' iron or other ore to form products of metal or metal compounds somewhat analogous to the. blast furnace used for making pig iron fromv iron ore.

My invention may be used for making numerous, different products by mixing and bringing to,-, gether a variety of different materials which when mixed together in special proportions and in the presence of heat, chemical reactions will take place whereby there is produced special desired products of metallic and other compounds.

An object of my invention is to provide mecha-- nical means for mixing steam, air or gas of any composition along with liquid or gaseous fuels into a combustion chamber and simultaneously therewith provide means for mixing and entering into and discharging from the said combustion chamber various types of materials in which chemical reaction may take place through heat produced in the said combustion chamber.

A further object of my invention is to provide in a single unit mechanical constructions which will feed a plurality of materials into a plurality of separated mixingchambers wherein mixing" will take place, and then discharge those mix- Figure 2 is a top plan sectional view, on a smaller scale than that of figure one, on line 22. of figure 1 looking in the direction of the arrows l-l.

Figure 5 is a. sectional View on line 5-5 of Figure 1.

In the drawings 2 indicates a combustion chamber lined with suitable material of vitrified character adapted to support any heated materials which may be entered therein The combustion chamber 2 opens into a large volume settlement chamber3 which is also lined in a similar manner to tlhat of chamber 2. This lining as to both of the chambers 2 and 3 is indicated by 4;

In the chamber 3 there is provided a vertical cylindrical or other "shaped discharge tube 5 which is closed at its bottom end and is provided with apertures 6 into the interiorof this discharge tube 5. ,The top of the tube 5 is covered over by a plate 1 and is provided with a discharge pipe 8 extending to any suitable means for exhausting gases from the tube 5.

The bottom of the settlement chamber 3 is provided with open spaces between what may be termed spokes 9, see Figure 2, of a wheel con- 4 struction, the hub of which supports the closed" tures simultaneously into a combustion chamber, wheregpnder the influence of heat chemicals,

reactions will take place, and do this without necessarilychanging the constructions of the f mechanicahpartfs of my mechanisms.

Reference will be had to the accompanying drawings in which apparatus.

Figure "'l' is a sectional elevation through my'l' end of the tube 5. Below the bottom of the spokes 9 there is the catch basin wall In set at an incline, into which there falls by gravity the materials that may result from the reaction which takes place in the combustion chamber 2. On its side this catch basin I0 is provided with asliding vertical gate block I! whereby access may be bad to the catch basin I 0 by thev opening ofthegatell.

The depth of the settlement chamber 3 below the combustion chamber 2 may be of any desired depth as to the ratio of distances for large installations of my apparatus. That distance may sometimes be required to be anywhere from ten to fifty feet deep below the apertures 6 in the tube 5. v

The-combustion chamber 2 may, as desired, be provided with vent openings l2, see Figure 1, which maybe closed by revolving gate l3 as de: sired having the handle knob I4.

The materials to be acted upon in the combustion chamber 2.

position in any suitable manner and for certain uses of my apparatus may be disconnected entirely from the combustion chamber 2 and may then be used as a unit or gun by itself. 1 This unit or gun may at times, if desired, be small enough to be held in the hand of an operator and used as a gun or a torch when this unit is suitably provided with means for delivering to it the materials to be acted upon. Or the tube may be made in dimensions and capacity for acting as a com-'- mercial blast furnace, as it were.

This tube l5 at its right end is closed. by a plate I6, and on the inside of the tube I5 there is mounted a central worm supporting tube H. The left end of the tube I1 is indicated b I8 and is supported at this end into the tube l5 by a spoke ring l9. In the tube I! at its left end there is' mounted a spoke ring the hub of which acts as a bearing for a worm shaft 2| on which is mounted worm blade 22. The worm shaft 2| is a tube and is mounted in a gland bearing 23 in the right end of the worm supporting .tube ll. The said worm shaft 2| extends to the right of the bearing 23 and is mounted insuitable'bearings 24 in a frame block 25.

- The frame block 25 is provided with suitable bearings for supporting an electric motor 26 or other suitable source of power which is geared to actuate a gear pinion 21 and the latter geared to drive a gear 28 on the aforementioned Worm shaft 2|. The worm shaft 2|, as before stated, is a tube and it terminates at its right end at 29 where it is mounted into a gland bearing 36 and in this gland 30 the tube 2| telescopes into a fixed pipe 3| mounted in the aforesaid frame block 25. The valve 32 controls the flow through the pipe 3 l.

Into the right end of the worm supporting tube N there enters from its top side a pipe 33 from a hopper 34. A conveyor belt 35 passes over a roller 36 suitably mounted and supported whereby materials which may be deposited on the belt 35 may be discharged from the belt 35 into the hopper 34, and by that means materials may be delivered to the worm supporting tube l1 and be carried by the worm therein to the left and be discharged directly into the combustion chamber 2. The action of the worm blade 32 will thoroughly mix any materials which are passed through the tube H by means of the revolutions of the worm.

On the inside of the tube l5 and on the outside of the worm tube I1 there is fixed a mixing block 31 which on its outside there is a recessed space 38 encircling the interior of the tube l5. This mixing block 31 is, as it were. a ring and lengthwise through this ring and on the inside of the ring, which contacts the tube ll, there is a series of longitudinal holes 39 extending through the whole length of the block 31. The space 38 is connected to the holes 39 by means of perforations 40 at intervals along the length of the series of holes 39.

On the outside and lower side of the tube l5:

there is mounted a vertical tube 4| which'is open to a chamber 42 which encircles the tube l 'l on the inside of the tube i5. This chamber 42 is open through the series of longitudinal holes 39.

At the left of the tube 4| there is mounted a vertical pipe 43. This enters the inside of the tube l5 opening into the recessed' spaoe 38 and thus fluid materials may enter by the pipe '4! and pass through the holes 39 into the recessed space 38 and then cut the pipe, 43 or a reverse motion of the fluid may enter pipe 43 and pass around to go out of pipe 4|, but therealpup.

4 pose of this construction is to provide the means whereby what will be entered to the inside of the tube l5 through the pipes 4| and 43 will be mixed together and pass out through the holes 39 into the chamber 44 which surrounds the tube l1 on the inside of the tube |5 at the left end thereof. Inside of this chamber 44 there is a coil 45 simulating a coil spring, but in fact is only a worm, the purpose of whichis to cause the material discharged from the holes'39 in the block 31 to move in a spiral manner around the tube and in the inside of the tube l5 and thereby the materials will become thoroughly mixed as they are discharged into the combustion chamber 2 as it passes through'between the spoke ring I9.

This construction as described in relation to the tube barrel l5 and its mounting provides means whereby materials may enter to the combustion chamber 2 from the pipe 3| and the pipes 4| and 43 and the hopper 34 simultaneously. The materials which enter to the combustion chamber 2 through thepipes 3| and 43 and the hopper 34 will become thoroughly mixed. What passes through the pipe 3| through the worm shaft 2| will act as desired as a blast drawing into the combustion chamber 2 what is delivered by the worm blade 22 and the pipes 4| and 43. Thus the pipe 3| may supply steam, air, gasor fluid burning oil. This will also be true of what may be supplied to the combustion chamber 2 through the pipes 4| and 43.

What is supplied through the medium of the hopper 34 may be granular or more or less liquid in form as desired and be thoroughly mixed during its movement to Where it is discharged within the combustion chamber 2.

By this construction and arrangement, ore or metallic material of any sort, together with fluxing material and carbonaceous or other material may be so proportioned that when it enters the combustion chamber 2, the temperature will be at such a high degree as to flux and smelt the said material instantaneously, causing the metallic elements to drop down into the lower region of the chamber 3 and accumulate in the catch basin id of the bottom of the chamber 3. Meantime the hot gases which are being released by the fusing and the smelting reactions will be car-- ried out through the tube 5 and through the pipe 8 to the cooling and condensing means which normally will be provided with cooling capacity which is expected to be sufficiently rapid to auto-s matically flow out of the pipe 5, as is indicated by the arrows shown on the drawings in Figure 1.

The alternating construction as shown by Figure 3, is to indicate that myjnvention is not limited to the use of a single volume settlement chamber, but those chambers may be duplicated in repetition to as many as may be needed in any given installation for any special purpose.v

In Figure A indicates a primary or first chamber to be entered by the discharge from any combustion chamber 2 and B indicates a supplemental chamber connected to the chamber A by the inclined pipe (3. At the bottom of each of given installation, there will be provided catch basins D for each chamber. In this manner there will occur a variation'in the character of the material deposits'from chamber to chamber as the settlementbf. the lighter product. naturally will occur later as compared to the heavier deposits that willtake place inthe chamber first to be entered.

I have used the descriptive words combustion chamber as the chamber in which the final chemical reactions take place on the materials which have been previously prepared, mixed and moved into the said combustion chamber. Not every chemical reaction which will take place in the use of my apparatus may be considered a combustion, and as I have used the word "comlbustion, it must be interpreted to cover any re actions which take place in a chamber of that class as relates to the materials to which are passed through the mechanisms which discharge those materials into what I have called a combustion chamber.

Many of the services for which my mechanisms provide the means for carrying out, are what are understood as deoxidizing, but I also use this apparatus for'oxidizing materials and have provided, as herein shown and described, means for not only deoxidizing but also for oxidizing materials which have been entered into the so called combustion chamber by means of my mechanisms.

My mechanisms provide for handling gaseous, liquid and granular materials. These mechanisms may also be used entirely with liquid and gaseous materials which will react in mixing together when passed through my mechanisms into the reaction chamber, which I have herein generally described as a combustion chamber.

What I claim is:

1. In an apparatus of the class described, a body supporting tube, said tube open at one end and connected to a combustion chamber, the

other end of said body tube closed providing a circular chamber on this closed end, a worm supporting tube mounted within the said body tube and passing entirely through the said body tube, amixing block mounted within the said body tube and over the said worm supporting tulbe, said mixing block provided with openings entering the said circular chamber of the said body tube and extending through the said mixing block, an entrance pipe into the said circular chamber of the said body tube, a ring shaped opening around the outside of the said mixing block and on the inside of the said body tube, a spiral coil for mixing purposes located on the inside of said body tube and on the outside of said Worm supporting tube, an entrance pipe entering the said ring shaped opening of the said mixing block, and the said mixing block provided with openings entering to the apertures through the said mixing block and to the said circular chamber.

2. In an apparatus of the character referred to, the combination of: a combustion chamber, a cylindrical body opening in said combustion chamber, means for supplying a combustible material to said body to provide a ring of heat at the open end of said body, a tube within said body opening in said combustion chamber, means to supply material to be treated to said tube, means to move the material in said tube toward the open end thereof, and means to inject the material so fed into the ring of heat, and means in said combustion chamber for supplying a ring of air around said ring of heat.
