RALPH L. GRAVES, OF SUMPTER, OREGON.

MINERS LAMP.

Specification of Letters Patent.

Patented May 7, 1907.

Application filed August 3,1906. Serial N0- 329,069.

To all whom it may concern.-

Be it known that I, RALPH L. GRAVES, a citizen of the United States, and a resident of Sumpter, in the county of Baker and State of Oregon, have invented a new and Improved Miners Lamp, of which the following is a specification.

My invention relates-to lamps of the character stated, and has for its object a new and improved lamp adapted for burning parafiinwax or other solid fuel.

The invention consists of the special construction, arrangement and combination of parts shown by the accompanying drawing, and hereinafter fully described.

In the drawing, Figure 1 is a central vertical sectional view through my improved lamp. Fig. 2 is a detail view of the conduct ive wick tube. Fig. 3 is a transverse sectional view of the wick tube, and Fig. 4 is a view of another form of similar wick tube.

In the practice of my invention, I employ any suitable form of miners lamp-body A, having an attaching hook B, a spout B, and if desired, a suspending loop C on the de tachable cap D of the lamp-body.

E denotes my improved heat conductive wick-tube, and F, the usual form of wick employed in lamps of this character. The wick tube E is constructed of a series of copper wires G, arranged into tubular form and secured by collars H, H, the collars being crimpedly or otherwise suitably secured to the wires, at the ends of the tubular arrangement thereof, preferably as shown by Figs. 2 and 3. A series of the wires G are projected beyond the collar H, forming extensions I. The wire extensions I are designed for arrangement in openings through the bodycap J, the openings being located ranging around the wick-collar K, and it is further designed that the ends of the wire extensions .be projected, adapted to be kept heated by the wick-flame. N ow it is apparent that heat thus set up in the wire extensions I will be conducted to the tubular wick-tube E, heating all the wires G thereof, through conductivity of the end collars H, H.

It is designed to secure the extensions I of the heat conducting wires by means of a suitable tubular ring L, asbestos or other noncombustible packing M being arranged next to the conductive wire extensions, substantially as shown by Fig. 1. While I prefer to secure the wire extensions I to the wickcollar K, as shown and described, other obvious means may be employed for the purpose without departing from the spirit of my invention. Obviously the user of my lamp can bend the wired extensions I outwardly, indicated by dotted adjustment in Fig. 1, and thereby cause the lamp flame to spread more or less, according to the adjusted position of said extensions 1. r

In Fig. 4 of my drawing, I show another form of the wick tube, the same being constructed of a conductive tubular body E, made permeable by a series of perforations E and one end of the tubular body fashioned into integral finger-extensions E the latter being designed for arrangement projecting through the cap J, into position adapted to be heated by the wick flame similar to the described heating of the wire extensions I. The main object of my invention being means to melt solid oils used in the lampbody, such as paraffin wax, and the like, and insure that the same be kept in fluid condition for absorption by the wick and conveying thereof to its lighted end.

WVith my improved heat-conducting wick tube, the fuel is retained into fluid condition no matter into which direction the flame is blown, since in any deflection of the flame, one or more of conducting extensions I or E would receive heat, and the same be conducted into the lamp-body to the tubular portion of the wick-tube, keeping the latter suitably heated for retaining the fuel into melted fluid condition.

I claim:

1. A wick tube constructed of a series of wires, collars adapted for holding the wires in circular arrangement, and a series of extension wires.

2. The combination with a lamp-body, of a wick tube constructed of a series of wires held in tubular arrangement by suitably attached collars, and a series of finger extensions at one end of the wick tube.

3. In combination withalamp-body, with around the wick supporting means on the means fzr supporting a wick, of a permeable lamp-body.

Wick tu e adapted for arrangement in the w lamp body, and a series of finger extensions I RALPH A 5 at one end of said wick tube, said extensions l \Vitnesses:

FRANK S. BAILLIE,

being adapted to project to the outer side of WM. H. PAoKWooD, Sr.
