VAPOR-BURNER FOR SOLDERING AND BRANDING IRONS.

SPECIFICATION forming part of Letters Patent No. 317,489, datedMay 12, 18 85.

Application filed September 12, 1883.

To all whom, it may concern.-

Be it known that I, LEoPoLD BAUMEISTER, a citizen of the Grand Duchy of Baden, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Vapor- Burners for Soldering and Branding Irons; and I do hereby declare the following to be a full, clear, and exact description of the inven' tion, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the class of devices which require to be kept heated while in usesuch, for instance, as soldering and branding irons-and the object thereof is to produce an iron which may be readily heated without the use of a furnace, may be kept hot for any length of time, and which may be laid down' for a few moments and again used without the necessity of reheating or placing in contact with flame, while at the same time the device shall be simple in construction, economical in cost, and easy to manage. With these ends in view, my invention consists in the construction and combination of parts, as hereinafter fully described, and then specifically designated by the claims.

For the purpose of enabling those skilled in the art to which the invention relates to understand and use my improved device, I will proceed to describe the same, referring by letters to the accompanying drawings, forming part of this specification, in which-- Figure 1 is an elevation of a soldering-iron embodymg my invention. Fig. 2 is a central longitudinal section of the same. Fig. 3 is an elevation of the burner, full size. Fig. 4 is a longitudinal section of the burner, wiclctube, and wicks, full size. Fig. 5 is an elevation, and Fig. 6 is a section, full size, of the filter in the vaporizer. Fig. 7 is an elevation of the vaporizer, full size. Fig. 8 is a section, and Fig. 9 an elevation, of a blue-flame tip, which.

may be substituted in lieu of the soldering-iron 3 iizer, as shown in Fig. l. Withm the reserfor plumbers and jewelersuse; and Fig. 10is a section of a branding-iron adapted to'be attached to the collet in lieu of the outer tube and the soldering-iron or blue-flame tip.

Similar letters indicate like parts in all the figures of the drawings.

A is the handle, ordinarily made of wood.

(No model.)

; B is a bulb or reservoir, which holds the benzine or other liquid hydrocarbon from which the vapor is generated. A tube, C, which is rigidly attached to the bulb, extends down through the handle, as will presently be more fully explained.

D is an aperture for filling the bulb, which is closed by thumb-screw D. A collet, B, threaded both externally and internally, is formed upon the bulb, to which the outer tube E, having perforations e and e, is attached by the-external screw-thread. To the opposite end of tube E the solderingiron F or blueflame burner Gis attached, as shown in Figs. 1, 2, 8, and 9. Attached to the collet by the inner screw-thread is a plug, H, which, owing to its peculiar construction, I term a vaporizer. The inner end-that is to say, the end toward the reservoirof the vaporizer is provided with a perforated block or plug, H. This plug is preferably screwed into the vaporizer, and is provided with a funnel-shaped opening, h, at its inner end, for a purpose presently to be explained. At the other end of the vaporizer is another screw-p1ug,H with a minute perforation at H hardly visible to the naked eye.

Between plugs H H is a filter, I. This filter consists of a tube of brass or other metal, the ends of which are closed by rolls #1 of wiregauze. Between; the rolls of gauze the tube is filled in closely with particles of a solder made of silver, copper, and tin in about equal quantities, as shown in Figs. 2 and 4. The burner K is attached to the outer end of the vaporizer. The burner consists of a tube, K, having peri'orarions k", a cage or coil, K of platinum wire attached to the outer end of the tube, and a tip, K having perforations and open at the top, as shown. I usually The tip is held on simply by the expansion of the tube. I usually attach the tube to the vaporizer by means of a flange, 70, which engages with a beveled stud, h, on the vaporvoir is a wick-tube, L, which I ordinarily screw onto the outside of plug El.

I have found it desirable to use two tubular wicks m m, one within the tube, and the other outside thereof.

With the wicks as shown it is a matter of split the tube part way down, as shown at w.

no consequence whatever in what position l the iron is held, as it will work equally well whether held horizontally or either end up. If held with the point of the iron down, the contents of the reservoir will, of course, settle l in the end of the reservoir toward the point whichhas no direct connection with the vaporizer. In this position the benzine or other fluid will feed up the outer wick by capillary attraction until it comes in contact with the inner wick at the other end of the tube. From this point gravity will assist capillary attraction in the inner wick, and the vaporizer will thus be supplied.

Within the handle and extending entirely through it is a tube, 0, the inner end of which is soldered to the bulb. The outer end of this tube is screw-threaded, both internally and externally. The outer screw-thread engages with ablock, N, in the outer end of the handle, and also with a nut, O. This nut has two internal screw-threads, between which is a shoulder, O; the larger screw-thread extends only part way through it, and is engaged by the external screw-thread of tube 0. A rod, P, extends through the nut and tube, and within the inner wick nearly through the wick-tube in the reservoir, where its beveled point P engages with the i'unnel'shaped opening it of plug H, which it is adapted to entirely close. The outer end of the rod is screwthreaded, and engages with theinner screwthread on tube 0, and with the smaller screwthread in nut O. The outer end of tube 0 is made slightly funnelshaped to accommodate a packing, Q, which lies between tube 0 and rod P, and restsagainst shoulder O in nut O, which 'acts to crowd the packing tightly in place, thus rendering the escape of vapor at 1 this point an absolute impossibility.

The operation is as follows: The reservoir is filled with any liquid hydrocarbonprefer- 1 ably benzine-and rod P screwed up tight to l, close the orifice into the vaporizer. The outer tube, E, is then held for a few minutes in flame (a spiritlamp will be found most convenient) to generate the vapor. As soon as the outer tube, and with it the burner, becomes thoroughly heated, rod P is turned backward to 3 open the passage into the vaporizer.

The vapor which forms at the surface of the liquid creates sufficient pressure to force it into the wicktube and through the inner wick. No air is admitted until the vapor has passed through the filter and into the burner-tube, where it is mixed with air before it reaches the coil, and meets another current at the coil, which assists combustion. The two wicks will I act to prevent the passage of any appreciable 1 quantity of benzine into the vaporizer, and the filter will allow nothing but the vapor to es cape, and that in a thoroughly purified condi- 1 tion, as no solid matter whatever can pass 1 through the rolls of gauze and particles of a l solder made of silver, copper, and tin in about equal quantities, which also control the quan- 3 tity of vapor that can escape. After passing 1 through the filter the vapor escapes into the burner-tube K at the minute perforation H in plug H In this tube the vapor is mixed with atmospheric air, which enters through perforations 'c in the outer tube and 7-32 in the air, which enters through the long perforations 6 in the outer tube, and perforations k in the tip. Combustion takes place at the platinum coil, which requires to be heated to white heat before the vapor is allowed to enter the burner-tube. As soon as the current of mixed vapor and air reaches the coil it takes fire. In

use a blue flame of intense heat is thrown into l the cavity F in the soldering-iron and out at the openings F 'When the blue-flame tip is used the flame passes directly out at orifice G.

The branding-iron R, (shown in section in Fig. 10,) is heated in the same manner as the other irons, the only change in construction being that the outer tube and arms R are cast in one piece, which is attached directly to the collet. The outer rim or band B of the branding-iron is secured to the arms by screws, as shown.

The letters (not shown) are cast upon the bottom R The flame acts upon the bottom, and thus heats the letters, but never comes in contact with the letters themselves, so that constant oxidation and wearing away of the letters is prevented.

1t are small holes for the escape of the vapors when the iron is in use. a

The materials used are not of the essence of my invention.

In practice I have'found it best to'make the reservoir and rod P of steel, the reservoir being made in two parts and soldered together, as shown at B I have adopted the globular form of reservoir on account of its great strength as compared with other forms, which is desirable on account of the pressure of the hydrocarbon vapor when the. iron is in use.

The burner, the soldering-iron, and the bottom letters and rim of the branding-iron I make of copper, the burner-cap and outer tube of iron, and the plugs of brass. In use this iron will be found to work without smoke or smell,

theiron laid down for fully five minutes. The vapor may then be turned on, and will instantly take fircat the coil.

1 am aware that the general arrangement which I have shown of reservoir, tubes, wicks, and iron, a hollow handle, bevel-pointed rod, 850., also the use of strands or a web of platinum wire, is not new, and also that numerous substances have been used as filters for vapor such as emery, sand, asbestus, broken glass, granules oflead and copper, and brass and iron filings-and I make no claim thereto, but

Having thus described my invention and referred to the state of the art, I claim-- 1. In a vapor-burner, a filter consisting of a tube closed at each end by a roll of wire-gauze or equivalent material, and filled with part icles of a solder made of silver, copper, and tin 1 in about equal quantities, as described, and for j the purpose set forth.

4. The globular reservoir and a filter of a 7 the platinum coil, and the tip K all combined 5 as and for the purpose set forth.

5. In a vapor-burner, plug H having a minuto orifice for the escape of vapor, the outer 1 tube having apertures e and e, and the inner tube having apertures k whereby air is admitted to mix with the vapor, in combination with the platinum coil and the tip having perforations k to admit air at the point where combustion takes place.

6. Plug H having aminute orifice, and plug H, having funnel-shaped opening, in combination with filter I, constructed as described, he inner and outer tubes perforated, as shown, the platinum coil, and the tip covering the same.
