IMPROVEMENT IN SVELFfKHELATlNG SMOTHIN-G-IRONS. i

Specification forming part of Letters Patent No. 181,266,1dated August 2A2, 1876; application filed November 12, 1875.

To all whom it may concern:

Be it known that I, JOHN S. HULL, of Oincinnati, inthe county of Hamilton and State of Ohio, h'aveinvented an lImproved Self- Heating Smoothing-Iron; and I do hereby declare that the following is a full and4 exact description thereof, reference being had to the accompanying drawings, making a part of this specification- Figure 1 being a side view of my improved self-heating smoothing-iron, provided with the self-heating apparatus; Fig. 2, a central longitudinal ver-tical section of the smoothing-iron proper; `Fig. 3, a top view of the smoothingiron, the top being removed.

Like letters designate corresponding parts in all of the figures.

The nature of my invention consists in a smoothing-iron provided with a close reservoir for containing a combustible iiuid, and the vpressure of compressed air for driving the iuid to the burner with sufficient force to produce a blowing flame; and with a self gas-generating burner for producing the iiame from the combustible uid; and also in the arrangement of the combustible-fluid reservoir above the smoothing-iron, so as to compact and bal'- ance the instrument for convenient use; and in the arrangement of an air-condenser, so as Ato serve the additional purpose of a-handle for the smoothing-iron; and in the construction of the smoothing-iron to diffuse and equalize the heat, and protect the hand from being burned thereby, all substantially as herein specified.

The principal parts of the instrument are the body, or smoothing-iron proper, A; the reservoir B, to contain a hydrocarbon oil or other combustible iiuid from which to produce heat; an air-condensing chamber, C, for condensing air in the reservoir; and a gas-generating burner, D, to produce a blowing iame, which impinges against the smoothing-iron.'

The smoothin g-iron A has a removable top, a, to which are secured supports b b, by which the reservoir Bis attached thereto and supported. The reservoir B may be of oany convenient shape, the cylindrical form shown being simple, convenient, and good in all respects. It has a removable stopper, d, at one end, by the removal of which access is had to the interior supplying the reservoir with the combustible iiuid; also, a vent-valve, f, to let offthe surplus air, if desired, at the close of its use at any time.

The condensin g-chamber is connected iixedly with the reservoir by twostandards, g g, one or both of which is hollow, to serve as a means of forcing the compressed air from the chamber to the reservoir. It either has a condensing-piston within, Yor the condensing-piston and barrel maybe a separate instrument, and temporarily attached to it only for forcing the air into it and the reservoir, and then detached, in which case an attaching-pipe, h, is employed, with a stopper, i, and check-valve l. This'condensing-chamber or tube serves the additional purpose of a handle to hold and l operate the instrument by.

The burner D is connected with the reservoir B by a connecting-pipe, m, and delivers the oil under pressure through a very small jet-aperture controlled by a line conical or needle point, which is provided atthe outer end of its shaft with a milled head, a, whereby to adj ust it.

When it is lighted, the heat of the Iiame communicates sufficient heat t0 the metal of the burner-jet to gasify the oil therein and produce a gas-jet, the pressure of which increases with the pressure of air upon the fluid in the lreservoir B, and the amount of which allowed to escape around the adjustable needle-point varies the length and heat of the iiame as desired. Air to supply the combustion is admitted through 'holes o o in a tube surrounding dame.

The flame of the burner is directed by the said tube p into the hollow smoothing-iron A, and is caused to impinge against a raised crossridge, r, of an interior plate, E, which rests on the bottom of the smoothing-iron, so that the said bottom is protected from too intense heat where the ame-burner strikes. This plate is best made of copper, to rapidly diiuse and equalize the heat over the bottom.

The products of the combustion escape through holes s sin the sides of the smoothing-iron.

To protect the hand of the user, a shield, Gr, made of asbestus, felt, or some other good-noncond uctin g material, is placed over the smoothing -iron, and beneath the reservoir B. It

is generally in the form of a plate, as represented.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with a smoothing-iron, of a close reservoir for containing a combustible fluid under pressure, and a compressed air chamber for producing the requisite press ure upon the Huid, substantially as and for the purpose herein specified.

2. In combination with a smoothing-iron provided with a close reservoir to contain a combustible fluid, and a compressed air chamber for applying pressure to the fluid therein, a gas-generating burner for producing a blowing ame in the smoothing-iron, substantially as and for the purpose herein specified.

condensing chamber, C, constructed vand arranged to serve the additional purpose of a handle for the smoothing-iron, substantially as and for the purpose herein specied.

4. In combination with a self-heatin g smoothing-iron, an interior plate, E, of copper, and provided with a shield-ridge, r, for diffusing and equalizing the heat of the burner-flame upon the bottom of the smoothing-iron, sub- `stantially as herein specified.

Specilication signed by me this 3d day of May, 1875.
