LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 241,418, dated May 10, 1881.

Application filed March 18, 1881.

To all whom it may concern.-

Be it known that I, ELIAS B. REQUA, a eitizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented new and useful Im pro vements in Lamp-Burners, of which the follow- 1 ing is a specification.

The present invention relates to that class of l lamp-burners which do not require chimneys,

and is particularly intended as an improvement upon theburner forming the subject-matter of Letters Patent No. 219,766, issued to myself on the 16th day of September, 1879.

The object ofv the invention is to supply an increased amount of air to the flame and interior of the burner for effecting a more perfect combustion and insuring a brilliant and uni- 1 form light, and, furthermore, for reducing the temperature at thelower end of thewick-tube, 1

so that the latter and the collar of the oil-fount will be preserved in a cool state, so that the 1 oil will not vaporize until it has well ascended 5 through the wick-tube.

Another object of the invention is to reduce ary manner.

I attain the results above stated by the construction and combination of parts hereinafter described and claimed.

In the accompanying drawings, Figure l is aview in elevation of a lamp-burner constructed according to the present invention. Fig. 2 is a central vertical section thereof. Fig. 3 is a detached view of the burner-base, lower deflector, and wick-tube, having oil-suppl y opening. Fig. 4 is a detached view of the fluted foraminous shell, the central or intermediate .cone, the hinged top cone, and glass deflector- Fig. 5 represents a modified form of holder. wick-tube having two screw-necks.

The letter A designates the wicktube, which has a screw-threaded neck at its lower end, formed ofthe metal composing the tube, for attachin g it to the screw-collar of the oil-fount.

(ModeL) Said wick-tube has outwardly-projecting horizontal arms a, to which the flanged base-plate B of the burner is attached. This base-plate is provided with a deflector or cone, 0,. on its upper side, which serves to conduct the air admitted below the base-plate to the wick-tube, passing upwardly thro'ughsaid deflector. The arms a are perforated, so as to offer no impediment to the free upward passage of the air. The wick-tube is provided with a housing or semi-cylindrical shell, D, which incloses the customary ratchet-wheels, (I, or other devicefor raising and lowering the wick. The shaft E of the wick-raisin g wheels is journaled in said housing, and the latter is arranged immediately above the base-plate of the burner, so as to place it at some distance above the base of the wick-tube and the oil-fount. The wickraising wheels project through slots in the wick-tube for properly engaging with the Wick. The location of the wick-raising wheels immediately below the burner-base or at some distance above the bottom of the wicktube will obviate the jamming of the wick in the tube, which latter result, is sure to take place when the wick raising wheels are arranged at the bottom of the wick-tube. An enlargement or chamber, a is formed in the wick-tube directly above the screw or attaching-neck thereof. This chamber has an opening which is closed by means of a slide or cover, b. By uncovering said opening the spout of an oil-can can be inserted into the same for the purpose of filling the lanip-fount with oil at any time.

The body of the burner is made separate from the base portion thereof, and consists of the lower flanged ring,F, the fluted and foraminous shell G, and the upper plate, H, formed or provided with the upwardly-projectin g cone 1. The upper plate, H, has a downwardly-projecting flange, h, which extends below the upper end of the foraminous shell G, and serves as a means for holding the same and interceptin g the upward passage of the air passing through the vertical channels of the fluted foraminous shell, so as to cause said air to pass through said shell and enter the interior of the cone I. Said cone has a series ofopenings at which is composed of the vertical ring J, the

horizontal plate or support K for the detachable glass deflector or flame-protector S, and the upper metallic or brass deflector, L, of the burner. The ring J is perforated around its entire circumference, and the plate K is also perforated thoughout its entire area. The plate K has the customary edge rim, L and a screw or other device for retaining the transparent flame-protector S. The lower plate, F, of the body of the burner has a vertical or downwardly-extending ring or flange, f, which fits on the flanged burner-base B, and the two parts are connected by means of a bayonetjoint or other form of joint, serving to effect a detachable connection between the body of the burner and its base portion.

It will be manifest that the fluted shell presents a large area to catch an increased amount of air, and the latter, in movingabout the channels and ribs or fluted portions, is intercepted and compelled to pass into the burner, instead of passing around the shell, as would be the case if the same were made with a plane outer surface.

The inner edges of the ribs, formed by fluting or corrugatin g the shell, extend nearly to the walls of the cone I, and thus it will be obvious that as the air ascends along the fluted foraminous shell the downwardly-projecting flange h of the top plate, H, will arrest or intercept the upward passage of the air and cause it to passinto the interior of the cone I.

The plate K intercepts the air as it rises, and a portion of the same is drawn in at the perforations of the ring J and conveyed to the flame. This result would not take place if the plate K were made imperforate. The transparent flame-protector supported upon the plate K is supplied with air through the perforations in said plate, and in this manner the brilliancy of the flame is further increased.

The position of the plate K at the top of the burner will enable almost the entire portion thereof to be exposed to the air, which will insure the production of a brilliant and uniform flame.

Itis not necessary to the successful operation of theburner to use the glass flame-protector or cone, which takes the place of the ordinary chimney; but ample provision is made for sup porting the same and feeding air into the interior thereof. An additional reason for maintaining the perforated plate K in an elevated position, in contradistinction to being located at the base of the burner, is to cause the air in its upward progress, when the oil is burning, to strike against the under side of the plate, when it is checked by those parts of the plate between the perforations, and the air then goes directly onto the flame over the cone.

As a modification of the wick-tube and fillin g device heretofore described, I contemplate using a wick-tube which has a filling-chamber, M, at its lower end, that is provided with two screw-threaded necks of varying diameters, so

as to enable a burner having such a wick-tube to be fitted into lam p-founts provided with different-sized collars. The filling-chamber, in the present instance, has an upwardly-extend ing nipple, which receives a screw-threaded plug or cap. A wick-tube of the description just specified has its wick-raising shaft titted in the cone-shaped shell, which is firmly connected with the wick-tube, so as to leave no opening between it and said tube. Projections or lugs 0 serve to receive and retain the baseplate of the burner.

I am aware that a lamp-burner has been provided with a corrugatedforaminous casing, to prevent agitation of the flame in moving the lamp, and such, broadly, I do not claim; and I am also aware that lamp-burners have been provided with intermediate removable collars, by which a single burnercan be applied to lampcollars of different size; but neither do I claim such construction.

What I claim is- 1. The burner base-plate provided with an open bottom and a wick-tube extended downward, and provided atits lower end with means, as described, to connect it with a lamp-collar, in combination with a channeled or fluted foraminous shell, provided at its upper end with a plate carrying both the perforated cone and the perforated exterior deflector, all substantially as described.

2. The combination, with the flanged burner base-plate, having a wick-tube provided with a screw-neck to connect with a lamp-collar, of 100 the channeled or fluted foraminous shell, havin g at its lower end the flanged ring F, detachably connected with the flange of the burner base-plate, and at its upper end provided with the flanged plate H, carrying the movable perforated deflector and the stationary perforated cone I, substantially as described.

3. The burner base-plate B, having perforated radial arms a, and carrying an attached air-deflecting cone, 0, in combination with the channeled or fluted foraminous shell G, surrounding and extending above the air-deflecting cone, and carrying at its upper end the perforated cone I and perforated deflector L,

substantially as described.

4. The combination, with the burner baseplate provided with the cone 0, constructed with a wick-tube projecting downwardly, and provided with means to support it on a lampcollar, and having the perforated arms a, of the channeled or fluted foraminous shell, de-

tachably connected with the burner base-plate,

and carrying the movable perforated deflector L and the stationary perforated cone 1, the movable deflector being provided with a perforated flange supporting the glass flame-protector, substantially as described.

5. The swinging perforated deflector L, hinged to the flanged plate H of the foraminous shell, and arranged over the perforated cone I, said deflector being provided with the perforated flange K, arranged immediately above the perforations in the deflector, and In testimony whereof I have hereunto set 10 supporting the glass flame-protector S, submy hand in the presence of two subscribing stantially as and for the purpose described.
