ARGAND LAMP-BURNER.

MOIFICATION forming part of Reissued Letters Patent No. 9,913, dated October 25, 1881,

Original No. 201,805,` dated March 26,1878. Application for reissue tiled September 7, 1881.

To di whom it may concern Beit known that I, CHARLES MARSHALL LUNGBEN, formerly ot' the city of Baltimore,

'ul the State of Maryland, but now of the city of New York, in the State of New York, have imllted certain Improvements in Argand Banners for Lamps, ot' which the following is aapeciiieation; and I do hereby declare that in the lame is contained a full, clear, and exdescription of my said invention, reference being had to theaccompanying drawings, and

tothe letters of reference marked thereon.

'Ik'.y invention relates to certain improvewenn in Argand lamp-burners.

These improvements consist in the combinoti., in an Argand lamp-burner,'of aserewthlded open-bottom base for attaching.,r the but to an oil-reservoir, a central air-tube, a latin-l air-passage establishing communicazo tion between the central air-tube and the extevion ofthe burner above the screw-threaded i of the base, a wick-carrier arranged amd the central air-tube above the lateral mire, and a rotary tube arranged above a 5 lateral air-passa ge, engaging with the wickelrn'er, and adapted to elevate or depress the m when rotated. l

The improvements also consist in the combillimnin an Argand lamp-burner, of ascrew 3o threaded open-bottom base for attaching the burner to an oil-reservoi r, a central air-tube, a lateral air-passage establishing communicatil. between the central air-tube and the exteli.' of the burner above the screw-threaded peltiol of the base, a non-rotary and open-bottom wick-carrier arranged around the central aibtnbe above the lateral airpassageaud a mty tube arranged above the lateralair-pasllpiengaging with the wick-ca rrer,and adapt- Y 4o ed toeievate and depress the same when rotated.

'lheinnprovements also consist in the comhindiomin an Argand lamp-burner, of a screwg threaded open-bottom base for attaching the i' 45 bm to an oil-reservoir, a central air-tube, a' lateral arpassage establishing communication between the central air-tube and the exterior of the burner above the screw-threaded portion ofthe base, a non-rotary open-bottom 5o wick-carrier arranged around the central airtube above the lateral air-passage, and a ro tary tube supported on the base above the lateral air-passage, engaging with the wick-carrier, so thatit will elevate or depress it when rotated, and, in conjunction with the central airtnbe, forming the wick-tube of the burner.

The improvements also consist in the combination,in an Argand lamp-burner, of ascrewthreaded open-bottom base for attaching the burner to an oil-reservoir, a central air-tube, a lateral air-passage establishing communication between the central air-tube and the exterior of the burner above the screw-threaded portion of the base, a non-rotary open-bottom wick-carrier arranged around the central airtube above the lateral air-passage, a rotary tube supported on the base above the lateral airfpassage, engaging with the wick-carrier, so that it will elevate or depress it when rotated, and, in conjunction with the central airtnbe, forming the wick-tube of the burner, and a chimney-gallery connected to the said rotary tube.

In the description of the improved Argand burner which followsreference is made to the accompanying drawings, forming a part hereof, and in which-` Fignre 1. is a central vertical section of a lamp-burner embodying my improvements,

and a portion of an oil-reservoir to which it is applied. Fi g. 2 is a similar section ot` the same, taken at right angles to the former. Figs. 3 and '4 are transverse sections of the burner, respectively, on the lines v w and w y, Fig. 1.

Similar letters of reference designate vsimilar parts in all the views.

A designates a iluid or oil yreservoir of a lamp.

B designates the central air-tube of a lampbnrner, closed at its lower end and connected by means of the lateral air-passages or'pipes a to the stationary tube G,which forms the base of the burner, and at the lower partis externallyscrcw-threaded, so that it maybe screwed into the reservoir A. The lateral air passages or pipes a establish communication between the exterior of the burner and thecentral airtube, and form the only means for admitting air to the central air-tube and to the interior of the flame.

D is a rotary screw-threaded tube, to which the chimney gallery or supporter E and shield or deector F are attached. This tube is supported above the lateral air-passages a by the base or tube U, as shown, through the' chimney-gallery resting on the top thereof.

The shield or deector F serves to conduct air to the exterior of the flame, the air being admitted to the shield or deflector through the lower portion of the chimney gallery or snpporter. This rotary tube D and the central air-tube, B, together form the wick-tube of the burner.

The wick-carrier (represented .by G) is formed of two cylindrical shells, b, connected by means of ribs c, and the outer shell is spirally grooved,

in order that it may fit the projecting thread on the pipe D. It will be observed that this wick-carrier is open at the bottom.

The central air-tube, B, is provided with a groove, d, in its outer surface, extending longitudinally thereof, and the inner shell of the wick-carrier G is provided with a projection, e, which fits within the said groove, and thereby prevents the turning of the wick-carrier during the rotation of the threaded tube D, for the purpose of elevating and depressing the wick.

The direction of air currents toward the flame is indicated by arrows.

In applyinga cylindrical wick to the burner, the part thereof intended to project below the ribs ofthe wick-carrier is slit to allow the passage of the wick past the said ribs and below the lateral air passages or pipes a. This slitting of the wick does not in any manner impede the dow of oil or fluid through the same, or affect the ame in any manner.

The burner, constructed as described, is comparatively inexpensive. The air-passages a admitting a current of air to the interior of the ilame,while the outer portion of the flame is supplied with air through the medium of the shield F, vperfect combustion of the duid isaecomplished, and a brilliant white light produced free from smoke and unpleasant odor.

The burner, being complete in itself, is applicable for use in lamps of the ordinary description originally iitted with the common Hat-wick burner without alteration of the lamp being made. This advantage will be appreciated when the superiority of the Argand principle is considered.

I do not claim, broadly, a detachable burner provided with a central tube having passages leading thereto from the outer air, as such a contrivance is not new; but,

Having thus described my invention, what I claim as new, and wish to secure by Letters Patent of the United States, s

l. In an Argand lamp-burner,- the combina.- tiou of a screw-threaded opeubottom base for attaching the burner to an oil-reservoir, a ceu'- tral air-tube, a lateral air-passage establishing communication between the central air-tube and the'exterior of the burner above the screwthreaded portion of the base, a wick-carrier arranged around the central air-tube above the lateral ai r-passage, and a rotary tube arranged above the lateral air-passage, engaging with the wick-carrier, and adapted to elevate or depress the same when rotated, substantially as specified.

2. In an Argand lamp-burner, the combination of a screw-threaded open-bottom base for attaching the burner to an oil-reservoir, a central air-tube, a lateral air-passage establishing communication between the central air-tube and the exterior of the burner above the screwthreaded portion of the base, a non-rotary and open-bottom wick-carrier arranged around the central air-tube above the lateral air-passage,

and a rotary tube arranged above the lateral air-passage, engaging with the wick-carrier, and adapted to elevate and depress the same when rotated, substantially as specified.

3. In an Argand lamp-burner, the combination of ascrew-tbreaded opeu-bottom base for attaching the bu-rner to au oil-reservoir, a ceutral air-tube, a lateral air-passage establishing communication between the centra-l air-tube and the exterior ot' the burner above the screwthreaded portion of the base, anon-rotary openbottom wick-carrier arranged around the central air-tube above the lateral air-passage, and a rotary tube supported on the base above the lateral air-passage, engaging with the wick-carrier, so that it will elevate or depress it when rotated, and, in conjunction with the central air-tube, forming the wick-tube of the burner, substantially as specified.

4. In an Argand lamp'burner, the combination of a screw-threaded open-bottom base for attaching the burner to an oil-reservoir, a central air-tube, a lateral air-passa ge establishing communication between the central air-tube and the exterior ot' the burner above the screwthreaded portion ofthe base, a non-rotary openbottom wick-carrier arranged around the central air-tube above the lateral air-passage, a rotary tube supported on the base above the lateral air-passage, engaging with the wick-carrier, so that it will elevate or depress it when rotated, and, in conjunction with the central air-tube, forming the wick-tube of the burner, and a chimney-gallery connected to the said rotary tube, substantially as specified.

5. The base or tube C, central air-tube, B, and lateral air-passages a, combined with the rotary threaded pipe D and wick-carrier G, the latter consisting of the shells b, united by ribs c, substantially as specified.

In testimony whereof I have hereunto subf scribed my name this 20th day of August, in the year of our Lord 1881.
