substance favorin combustion', 1 s forced through the centra ly located air pipe. Fuel gas and oiq/genous gas substances mixed bymeans -of'a-blowpipe produce a higher heat than one-'brought about by the usual ga-s burner, howevert-he heat generated by a single gas and air or gas and oxygen blowpixeis not sutlicient for many purposes.

he object ofl my invention is to' c'onstruct `a blowpipe with two or more separate 'gasf andairexitsand to place these exits nsuch a position lthat the driven flames meet in one point. The, heat of l;the blowin concentrated upon one place an a quicker,

much higher heat is obtained than in' the single ending ordinary blowpii My improvement is anv a use of small sharp flames as well as inthe conflagration voftwo o'rmore large blowing flames for heating purposes.

My improvements lead to a blowpe with one main tube for fuel gas Adivi ing into branch tubes and one main tube for oxggenie gas dividing into branch tubes; t e relative dis osition of the respective tubes as well as t ie way of connecting the main tubes with the sources'of glas supply and the shape of the end pipes a lowing for the termination in converging direction are special points of novel character. The converg- 'ing direction of two or more flames is of great value in solderingl') pipes, plates, or

articles which are held y a plaster compound in their relative position during the soldering process as the eat can be applied from more than one side. l

The section'al'figure of the accompanying drawing illustrates a blow ipe with two gus exits the construction of which is as follows:

posteriori The main tube, M, is perforated at t e points B and C and surrounded by a siiu fittinfr sleeve, N, having tube projections and These projecting. tubes I and Y communicate with the interior of the main tube whentheir interior openings are vplaced upon the 'perforations of the main tube; this is simply done b turning the sleeve N around its longitu inal axis until the opening of the tube I is adjusted .upon the opening, B, of the tube M, when at the same time the opening of the tube Y is directed upon the openin C of the tube M.

The letter U indicates t e main tube for oxygenic gas substances (air, nitrous oxid, oxygen, etc.) this main air tube U is closed toward-the anterior part of the main gas tube, M, by the fitting R, which separates an anterior space from a posterior space in the main tube M.

The fitting -T divides the main as tube M' into branches, the fitting T2 divides the vmain'aii' tube Uf into branches. The sub dividing-ends of the dividing fittings may be directed infganysuitable-angle to the directionf'offf'the main tube M. The branch .tubesfgor'f'air onother oxygenic gas substances are thus distributed to therespective branchitubes for fuel as: The fuel gas enters-the blowpipe at' and leaves it at G and G. The air or oxygenic gas enters the -blowpipe at A and leaves it at A and A2. l fir-.,lliirnin movements of the sleeve N regu- -latethe istribution of as and air so that while the blowpi e is hel with 3rd, tith, and 5th fin er of the and, thumb and forenger c ontro the regulation of gas and air admission.

The handle screw, H, tightened upon the spindle, D, of the nipple, E, by the set screw, S, makes a firm connection with the main tube, M, around vwhich the sleeve, N, rotates. The amount of gas, G, and air or oxygenous substance, A, to be passed through the respective tubes is dependent upon the osition of the openings of the tube, I an Y, over the rforations,l3,:in l, C, of the main tube, M. hile a full supply and large flames are obtained by placing the internal openings of the gas and air su ply tubes, I, and, exactly over the perferations B, and, C a diminution of gas and air .supply and-small needle flames are obtained in c angin the position of the tubes, I, and, .Y, from t e positionmentioned before by anaxial movement of thesleeve, N, to the right orv left. The bloivpi e is manipulated l- 4by holding the handle wit Br d,-4th' and 5th tin'gelof the hand while the'sleeve,` N, is

The curves'of the branch tubes'may be more or lessV pronounced so that the converging flames may meet at any desirable angle. Anyzdesired number of branches may be .ittedat the end of the main as tube.

Having now fullydescribe myinvent-ion I claim.: v

-1.. Blowpipe for combined use-of fuel gas and .oxygenous vgas substances consisting of one larger main tube for fuel gas divided Into terminal branch tubes, and one smaller main I tube for oxy enous gas substanceswhich In turn is divi ed into terminal. branch tubes, said tubes: for oxygenous as substances suspended-,throughout in sai tubes for fuel gas xn such manner that the larger main tube for *fuel lgs carries in its interior the smaller main tu for oxygenous gas and each one oftthe terminal branch tubes for oxygenous and .-oxygenic gas4 substances .havin gas is disposed in the interior of one of the for fuel gas carries in its interior the smaller main tubefor oxy enic gas and each one of the'. terminal branc tubes for oxygenic gas is disposed in the interior of one of the branch tubes for fuel as, the ipes of said branch tubes bent to al ow for t Ieir termination inta converging direction substantially as described and shown.

3. Blowpipe for combined use of fuel gas and oxygenic gas substances having one larger main tube for fuel gas divided into terminal branch tubes, onel smaller main tube for oxygenic gas substances which in turn is divided into terminal branch tubes, and a sleeve surrounding the larger main tube; the tubes for oxygenic gas substances suspended throughoutin the tubes for fuel as xn such manner that the larger main tu )e for fuel gas carries in its interior the smaller main tube for oxygenic as, and each one of the terminal branch tu es for oxy enic gas is disposed in the interior of one o the branch tubes for fuel gas, said main tube provided' -with an anterior lateral wall perforation for the passage 'of fuel gas und a posterior lateral wall perforation for the passage of oxygenic gas substances, said sleeve carrying a supply tube for fuel gas and one for oxygenic gas substances, being attached swivelmg around vt-he larger main tube in a osition intwhich the opening or closing o the gas ways` is elfectuated by turning the internal openings of the sup ly tubes on to or ott` from the respective iva l perforations of the larger main tube,
