SOLDERlNG-IRON.

SPECIFICATION forming part of Letters Patent No. 369,617, dated September 6, 1887.

Application filed July 2,1887. Serial No. 213,247. (No modeLl T0 ctZZ whom it may concern.-

Be it known that l, CHRISTIAN G. SoiINEI- DER, a citizen of the United States, residing at Washington, in the District of Columbia, have invented a certain new and useful Improvement in Soldering-Irons, of which the following is a full, clear, and exact description.

This invention relates to that class of solderingirons in which the copper or bolt is heated by being applied to a gas-burner, the flame from which'enters the said copper or bolt, and then, passing out, envelops it.

The invention consists in a soldering-iron having a copper or bolt provided with an interlor cavity opening externally and forming a gas-cham ber, whereby the copper or bolt may be applied to or have applied to it an ordlnary illuminating-gas burner with'a flame, the flame filling the said chamber and escap- 1ng outwardly therefrom and enveloping the copper to heat it.

The invention also consists in a spring-handle for automatically engaging the bolt, the bolt being swiveled to the said handle, and thereby adapted to be used in alignment with t or at right angles thereto, for convenience in getting at the work in hand.

In the accompanying drawings, in the several figures of which like parts are similarly designated, Figure 1 is a perspective view of my soldering iron applied to an ordinary bracket illuniinatinggas burner. Fig. 2 is an elevation, with the bolt or copper in section. Fig. 3 is a similar view of another form of bolt, and also shows the bolt provided with aburner so that it may be connected by a tube to a gas burner, and thereby receive a constant flame or carry the heat-producing agent along with it. Fig. etis a side elevation, with the copper or bolt shown in two positions, the tip of the copper being broken off and the end of the handle also being removed to come within the sight of the drawing; and Fig. 5 is an elevation of the bolt turned down at right angles with the handle, part of the handle being also shown.

The bolt a may be of any ordinary construction so far as external shape and material are concerned. I provide it with an external projection at the base of the tinned portion,whioh projection is shown as a bead, b, in Figs. 1, 2,

4, and 5, and as a shoulder, Z), in Fig. 3, for a purpose hereinafter explained. Either or both forms are comprehended in the term projection. I also provide the bolt with opposite openings or sockets, c, to receive the ends of the handle d, and, furthermore. I provide it with transverse grooves e and intersecting longitudinal groovesf, which respectively engage the limbs of the handle when the bolt is turned at right angles thereto or in alignment therewith.

The handle d is composed of metal bent in the form of a bow, and having the free ends of its limbs d d turned in toward each other to form gudgeons g, which enter the openings or sockets c, to engage and hold the bolt. The limbs'of the handle d are forced toward each other by the elasticity of the metal, and this elasticity is sufficient to firmly grip the bolt and hold it in either of the positions described.

The bolt is provided with a central cavity, h, which may be made with parallel sides, as indicated in Fig. 2, or which may be made spherical, or nearly so, as indicated in Fig. 3, and this chamber communicates with the external atmosphere by means of openings 6, which are arranged just beneath the projection, hereinbefore referred to.

Vhen the bolt is applied to a gas-burner, as indicated in Fig. 1, the gas having been lighted, the flame will issue from the holes 3, and, passing over and around the projection, will lick around the point of the bolt or copper and thus heat it. The projection will serve to arrest whatever soot there may be, and thus keep the point of the copper or bolt clean. The requisite quantity of air is ad mitted into the bolt or copper by the transverse intersecting channelsj and the openings k. I have found that the desirable blue flame in which there is practically no soot-that is to say, in which the combustion is practically perfect-is best obtained by employing a gaschamber substantially of the shape indicated in Fig. 3.

Long prior to this invention it was common to supply to a bolt means for burning illuminating gas by connecting the soldering-iron with a source of supply by means of a flexible tube which would not interfere with the manipulation of the soldering-iron by the workmen. I have indicated such a connection with my improved soldering-iron in Fig. 3. In this form of soldering-iron the bolt is pro vided with any suitable burner and nipple, Z, to which a flexible tube, at, may be attached, and then connected to a source of gas-supply.

In the use of my soldering-iron it will be advantageous for the workmen to have two or more irons, so that while one is in use the other may be heating over a gas-burner.

The handle (Z may be made of rod metal doubled upon itself to form the limbs d d and the hand-grasp d the latter being made bulging, so as to render the limbs d cl springy. The limbs d (1 may diverge slightly from the upper end of the bow of handle d, so as to grasp the copper or bolt more firmly, the ends of said limbs next to the gudgeons g g lying in the grooves e or f, in accordance with the position the bolt may be placed in with respect to the handle. The roof of the gaschamber may be arched or flat, or any other approved shape.

YVhat I claim is 1. In a soldering-iron, a bolt or copper having an internal gas-chamber provided with flame-outlets and air-inlets, and an external projection arranged above the flame-outlets, substantially as described.

2. In a soldering-iron, a bolt or copper pro vided with an internal gas-chamber of spherical or nearly spherical shape, as set forth, and provided with air-inlets and flame-outlets, and a handle, to which said bolt is pivoted, substantially as described.

3. In a soldering-iron, a bolt or copper having an internal gas -chamber spherical or nearly spherical in shape, as set forth, provided with air-inlets and flameoutlets, and a shoulder arranged above the said flame-outlets, substantially as described.

4. In a soldering-iron, a copper or bolt provided with sockets c and grooves e and f, combined with a handle having gudgeons and spring-limbs engaging, respectively, the said sockets and grooves of the bolt, substantially as described.

5. The combination of a copper or bolt having an internal gas-chamber provided with air-inlets and flame-outlets, and also having sockets c and grooves c andf, a gas-supplying device attached to said copper or bolt, and a handle secured in said sockets and engaging the said grooves as the copper or bolt is placed in position, substantially as described.

6. The copper or bolt having an internal gas-chamber provided with air-inlets and flame-outlets, and also having sockets c and longitudinal and transverse grooves, combined with the spring-handle engaging the sockets and grooves, substantially as set forth.

In testimony whereof I have hereunto set my hand this 30th day of June, A. D. 1887.
