To al 107mm it may conca-nk',

Be it known that I, GEORGE CKELHAUPT,

of the city of New York, borough of Manhattan, in the county and State oljNeW York, have invented a new and Improvleld Furnace for Heating Soldering-irons, of which the following is a full, clear, and exact description.

The invention relates to furnaces used by plumbers and other'meehanicsg' and its'object is to provide a new and improvedfurnace for heating soldering-irons and the like tion of the improvement vonV the line 1 1 in Fig. 2. Fig. 3 is a sectional plan view of the same on the liuc 2 2 in Fig. 1, and Fig. 3 is a transverse section of the same on the line 3 3 in Fig. 1.

The improved furnace for heating soldering-irons is provided with aportable casingA, preferably made of sheet'metal and having legs A' and a firebrick lining l5 in the upper portion, thc front and bottom ofthe casing being open, to permit'of introducing the soldering-irons through the openfront and to allow ai r to pass through the open botto'm to a burner U. A burnerCextendsinalongitudinaldirection in the casing below the fire-brick lining, as is plainly indicated in the drawings, and it consist-s of two longitudinal pipes C and C, connected with each other at their ends by cross-pipes C:i t1, of which the pipe Gais su pported in a suitable bracket D, attached to a.

thereof.

cross-bar A2 of thc easing at'thc open front The rear cross-pipe C4 terminates in a vlongitudimtlly-e1-itending pipe C, supported in and extending through the rear end of the casing A, and in the bottom of this pi pe C5 is formed a large air-inlet C6 for allowing nir topass into the pipe and mix with thegas supplied through a pipe E, connected with a suitable source'of gas-supplynnd opening in a small jet into the extreme rear ond of thc pipe C", as ls plainly shown ln Fig. 1. A

ined February 3,1899'. sean No.7o4,a'11. (Nomaden valve Eon the supply-pipe E serves to regulate the amount of gas allowed to pass into the pipe C5, andv thus insures a proper mixing ofl gas and air. The longitudinal pipes C' and C2Lare provided at their inneropposite sides with rows of apertures C7 for the iniiammable mixture of gas and air to passl through in small jets, said apertures "being protected against scales or other small par tioles by overhanging projections or 'lugs Cs, secured on said pipes. (See Fig. 3.)

Now it is evident'that when 'the valve E is.

opened a vmixture oigas and air is formed in the pipe C5, and this mixture Hows from 'said pipe, through the pipe Cilinto the vlongitudinal pipes C C2 to issue from the 'same in small jets through the apertures C7, and this mixture is -ignited at theapertures to produce jets of flame for'heating the irons supported'above the' b urneronga' pair of supports F, each made with two upwardly-curved arms'F' F2, adapted to rest on the to'p of the pipes C' C2, respectively.- The middle portions F3 of the arm-supports F are'pivotally connected with downwardly-extending arms G,secured on alon gitudinally-extendin g shaft II, mounted to turn and to slide in suitable bearings A'S'Ai, arranged on the casing.

The forward end of the shaft H projects somewhat-at the'front of the easing` and' is provided at its end with an arm I for turning said sh'aft to swing the arms Geither to thc right or to the left and move the arm-supports F from their normal central position (show'n in full lines in Fig. 3) into a sirlewise position, as Vindicated in dotted lines in Fig. A

3, so that only one of the arms F' or lfistnnds midway between the two vpipes C' C'- to bring a soldering-iron supported on said curved arm directly over the jets of llame issuing from the 'pipes C' C.

The arm-supports F can be locked in 'their normal position (shown in full lines in Fig.

3) by sliding the shaft II rearwardly to bring'l akey II on said shaft in engagement with a corresponding aperture formed in the benring A, so that the shaft cannot be turned. (See Figs. 1 and 2.) v'

When it is desired to change the position of the arm-supports, the operator pulls the hu-lnllel outward and slides the shaft ll in thc name direction, so as t'o discngago the key IOO H' from the aperture in the bearing A to per- .mit of turning the shaft H, and thus bring either set of curved arms F' or F2 between the burner-pipes C andC2.

The overhanging projections C8 are preferably provided with cut-out portions C9 (see Fig. 2) for the arms F' F2 to pass into when moved into a middle position, as above explained.

Below the shaft II is arranged a pan J, removably supported on brackets carried by the legs A', said pan being adapted to receive any dross or scales or other matter falling off the solderingirons placed on the supports F. "When the supports are in the position shown in Fig. 3, two soldering-irons can be placed on the two sets of curved arms F and F2 and heated by the jets of flame issuing from the pipes C' and C2, as above explained, and when it is desired to heat a single iron very quickly the operator shifts the shaft H, as previously explained, by unlocking the shaft from its bearing and swinging the arm I over to one side, by striking the arm with the solderingiron, and then placing the soldering-iron into the set of curved arms F' or F2, extending between the pipes C' and C2.

Apfurnace constructed in the manner described is portable and by means of a rubber tube or the like can be connected by the pipe E with the gas-pipe in a building for supplying the-necessary amount of gas for the inflammable mixture, as above explained.

The top of the casing A may be provided with an outlet-opening K, as indicated in Fig. l, so that when the cover of this opening is removed an increased draft is had for the burner. 4

Having thus fully described my invention,

I claim as new and desire to secure by Letters Patent- 1. A furnace, comprising acssng, a burner in the ,casing and consisting of a plurality of pipes, a support consisting of. oppositeiy-extending arms, a shaft on which the support is mounted, the said 'shaft being adapted to rock in the casing, and means for locking the shaft to hold the support in a central position relatively to the burner, substantially as specified.

2. A furnace for heating soldering-irons, comprising a casing open at ons end and vat the bottom, a burner arranged in said casing and formed of a plurality of apertured pipes connected with a mixing-pipe hayiugan airinlet and a gasulet, s pair of supports each in the form of' ti'o curved' arms ads ted to rest on said 'apertnred pipes, arms or the supports, and a shaft moued to turn and to carry said arms, substantially-as shown and described.

3. A furnace for heating soldering-irons, comprising a casingopen at one end and lat the bottom, a burner arranged in said easing and formed of a plurality of apertured pipes connected with a mixing-pipe having au airinlet and a gas-inlet, a pair of supports each in the form of two curved arms adapted to rest on said apertured pipes, arms for the supports, a shaft mounted to turn and 'to carry said arms, and means, substantially as described, for locking said shaft against rotation, as set forth.
