SOLDERlNG-IRON.
SPECIFICATION forming part of Letters Patent No. '765,641,6.ated July 19, 1904.
Application led December 2, 1903. Serial No. 183,455. (No model.)
To all whom it may concern.:
Be it known that we, NEIL A. SULLIVAN and WILLIAM F. RYAN, citizens of the United States of America, and residents of Cincinnati, county of Hamilton, and State of Ohio, have invented certain new and useful Improvements in Soldering-Irons, of which the following is a specification.
The object of our invention is to provide a soldering-iron of the kind that is heated by the ignition of vapors from a reservoir carried by the iron, in which the vapors come to the burner in a highly-gaseous condition and issue therefrom1 in a state to produce theoretically perfect combustion, in which the feeder for the oil is not affected by the position in which the operator holds the iron, and which is provided with a ready means for igniting and for regulating the flame.
The object is reached bythe means illustrated and described in the accompanying drawingsand specification.
Referring to the drawings, Figure 1 is an elevation of a soldering-iron embodying our invention. Fig. 2 is a central section of the same. Fig. 3 is a detail perspective view, upon an enlarged scale, of the vapor-chamber and burner with the burner-tip removed. Fig. 4 is a detail sectional view, upon a still more enlarged scale, of the upper end of the oilchamber and the needle-valve. Fig. 5 is a plan view of the upper ends of the external and internal tubes. Fig. 6 is a perspective view of the burner-tip. Fig. 7 is a' central sectional view of the air-pump.
Referring to the parts, the fuel-reservoir A has a recess in its base t and has its upper end a tapering. Extending centrally through the base c and through the upper end a of the reservoir are two tubes, an outer one B and an inner one C, leaving between them an oil-passage b. The lower end of the pipe B is internally screw-threaded to it over the external screw-threads of the coupling D', which is secured to the base a, and the lower end of pipe C is externally screw-threaded to fit into the internal screw-threads of the coupling D. The upper end of the pipes C and B are soldered or swaged together, as shown in Fig. 5, except for a series of small holes c. Within the reservoir A is a feed-pipe 7)', which taps into the pipe B in the upper part of the reservoir A and thence curves outward adjacent to the walls of the reservoir and follows the contour of the walls, projecting at its lower end into the groove c2 between the recess c and the walls of the lower end of the reservoir. The purpose of having the pipe b' of this form is that it will feed the liquid from the reservoir into the pipe B in whatever position the reservoir may be held.
The upper end b2 of the pipe B is externally screw-threaded to receive a casting D, within which is formed a vapor-chamber d and at the upper side of which is a nipple d', forming a needle-valve seat d. Casting D has casty integral with it two upwardly projecting pipes d3 0X4, forming the chamber for superheated vapors. At the upper ends the pipes Z3 al* are formed integral with a ring d5. Nipple d' is surrounded by an ignition-cup CZ, within which asbestos Z7 may be placed, and is externally screw threaded to receive a burner-tip E. Extending centrally through the pipe C is a stem F, pointed at its upper end f to form a needle-valve. The lower end f of the needle-valve is screw-threaded to engage the internal screw-threads of the coupling D and has a pin f2 within the recess a for the purpose of regulating the opening of the needle-valve.
The ring d5 has a set-screw g, by means of which a short tube g is secured to the ring. Tubing g has perforations in its upper edges to receive .set-screws by which the solderingtip G is secured to it. Below the solderingtip the ring g has a slot g2 opening into the atmosphere. Surrounding vthe casting D is a perforated housing. H, which consists of a tube having a perforated flange at its lower end to contact the pipe B, so as to form a hot-air chamber h3 and allowing the housing to reciprocate. The upper end of the housing I-I has an angle-notch it', as shown in Fig. l, to engage a pin ft2, which is secured to the upper end of the pipe al4L to lock the housing H in its upper position when desired. The pipe B has surrounding it a perforated sleeve J, by which the soldering-iron is held, the sleeve being perforated to keep it cool.
Reservoir A has an opening in its top in which is located a sleeve m, to which is secured a tube M, which projects into the interior of the reservoir. In the sleeve m is located a packing-gland n, through which passes a rod N, to the lower end of which is secured a leather cup. Located in the interior of tube M is a perforated disk m', which upon its upper side is screw-threaded to engage the lower screw-threaded end of the stem N and the lower side of which is beveled toform a seat m2 for a valve R, which is held upward by a spring r, the lower end of tube M having a perforated plug m3 in it.
In operation gasolene is placed in the reservoir A by removing the packing-gland n and the piston n from the tube M, the needle-valve being carried to its seat Z2 by turning the endfz. Then pump is replacecL-and a small pressure of air is placed upon the gasolene by operating the pump, after which the stem N is turned so that its screw-threaded end engages the disk m' to prevent any leakage of the air intothe pump and likewise to assist the valve R in retaining the pressure of air upon the liquid in the reservoir. The housing H is then moved downward to uncover the casting D,` and the needle-valve is opened,-the burner-tip E removed, and a small amount of gasolene is allowed to flow through the needle-valve into the ignition-cup (W. The needle-valve is then closed, the burner-tip is replaced, and the liquid in the ignition-cup is ignited, and after it has burned awhile, generally until the liquid in the ignition-cup is almost burned out, the needle-valve is opened and the vapors issue therefrom through the burner-tip and burn with a hot blue flame. The pipes Z3 d* adjacent to the {iame serve to superheat the vapors therein, which are thence carried into the vapor-chamber (Z and press back into the passage between the pipes C and B, so that the vapors issuing from the needle-valve will be in a highly-gaseous state. After the flame has been ignited at the burner the housing H is pushed up and locked in position, so as to protect the iame Jfrom drafts. The iiame is then directed against the bottom of the lower side of the soldering-tip G and issues likewise through the opening g2. This flame issuing through the opening g2 is utilized in heavy work to heat the metal which is being soldered to prepare it for soldering metal by the burner-tip.
The contracted openings c, while preventing a free flowing of the gasolene into the vapor-chamber d, allow the gasolene after it has become vaporized to pass freely into the vapor-chamber. rThus the tendency is to have the vapors in the chamber Z in a highly-gaseous state.
The position of the feed-pipe b permits the operator to use the soldering-iron in any position lwithout interfering with the flow of the liquid' into the passage b and likewise feeds the liquid from the reservoir A until there is practically none left therein. When the operator wishes to put the soldering-iron aside for a short while, he may lower the flame by means of thc needle-valve readily, and the liat base with the recess a allows the iron to stand firmly upon the reservoir A, as shown in Figs. 1 and 2.
WV hat we claim is- A soldering-iron consisting of a reservoir and two tubes extending therethrough leaving a passage for liquid fuel between them, means of communication between the passage and the reservoir, a vapor-chamber at the upper end of the tubes having formed in it a needle-valve scat and an elongated stem extending through the inner tube having at its upper end a needle-valve seated against the valve-seat and a soldering-tip secured opposite to the opening of the needle-valve substantially as shown and described.
