SPECIFICATION forming part of Letters Patent No. 241,050, dated May 3, 1881.

Application filed February 23, 1881.

T 0 all whom "it may concern:

Be it known that we, JAMES M. G. MoUoK and CHARLES F. GEORGE, of Fairfield, in the county of Jefferson and State of Iowa, have invented certain new and useful Improvements in Lamp-Burners; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a perspective view of our improved lamp-burner. Fig. 2 is a vertical sectional view of the same, and Fig. 3 is a detail view, in perspective, of the lower part of the burner.

Corresponding parts in the several figures are denoted by like letters of reference.

This invention relates to lamp-burners; and it consists in certain improvements in the construction of the same, which will be hereinafter fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, A represents the perforated diaphragm or bridge, which is extended or continued to form an an nular flange supporting the chimney-holding springs B, and has hinged thereto the cone, cap, or deflector O of the burner. The said cone, cap, or deflector is provided near its base with one or more slots or apertures, D, the object of which is to prevent the lower part of the burner from being overheated by admitting the ingress of cold air.

The wick-tube is made in two parts, E F, the upper one of which, E, is fixed in diaphragm or bridge A, and the lower one in the cylinder G of the burner, which contains the screw or other mechanism, H, for raising the wick, and which is screw-threaded at its lower end, as shown at I, for attachment to the oil-reservoir of the lamp. This lower part of the burner is hinged to the under side of the extended diaphragm A at a by one of four arms, N, the outer bent ends of which are sprung into slots in the rim of the flanged dia- (No model.)

phragm, as shown in Figs. land 2; and by reference to the last-named figure it will be seen that the upper section, E, of the wick-tube is made flaring at its lower end, as shown at J, so as to enable the wick to be easily raised up through it, and also that it is slotted at its lower flaring part, as shown at t 1', below the diaphragm A, which permits air to enter the wick-tube at this point, and also permits the escape of oil, with which the wick may be ot'ercharged, as it enters the upper contracted part of the tube above its flaring mouth J. This construction of the wick-tube prevents its lower section, and consequently the part of the burner in which said lower lower is secured, from bein g overheated.

The cylinder G is provided at its upper end with an annular rim, K, forming a cup-shaped receptacle, L, from which an opening or passage, M, adjoining the wiclet-ube, leads to the bottom of said cylinder G. Any oil raised in the wick by capillary action while the lamp is not burning, as well as any oil that finds its way through the slots or aperturesz' in the upper section of the wick-tube, will escape into the cup L, and from thence find its way through opening M back to the oil-reservoir.

Explosions of lamps are frequently (almost invariably) caused either by the excessive heating of the burner while in use or by the accidental ignition of the inflammable fluid raised through the wick-tube while the lamp is not lighted and flowing-over the burner. By our improvement any accident from these causes is rendered impossible. The only parts of the burner liable to become overheated--viz., the cap and the wick-tube-are practically isolated from the lower part of the burner, and the oil raised by the wick and not consumed can escape only into the cup L, from whence it is bound to return to the oil-reservoir, thus not only avoiding danger, but also unnecessary waste of the illuminating-fluid, while at the same time cleanliness is vastly promoted.

Having thus described our invention, we claim and desire to secure by Letters Patent of the United States- In a lam p-burner, the combination of the cylinder or ratchet-chamber Gr, having wick tube F and cup-shaped receptacle L, provided with the passage M, hinged diaphragm A, havin g wick-tube E, provided with a fiarin g mouth, J, slotted at t '1', and hinged burner-cone (3, having a series of slots or apertures, D, at its base, substantially as and for the purpose herein shown and described.

In testimony that We claim the foregoing as ourown we have hereto aflixed our signatures in presence of two witnesses.

JAMES M. G. MOUCK. CHARLES F. GEORGE.
