MINERS LAMP.

Specification of Letters Patent.

Application filed December 2, 1908.

Patented Sept. 14, 1909.

Serial No. 465,645.

To aZZ whom it concern:

Be it known that I, ADLETIA MAE VAN Lrnw, a citizen of the United States, and a resident of Houghton, in the county of Houghton and State of Michigan, have invented a new and Improved Miners Lamp, of which the following is a full, clear, and exact description.

This invention relates to miners lamps for burning oil, wax and the like, and more particularly to a lamp of this class comprising a body, a wick tube projecting through the spout of the body, and a member removably mounted upon the wick tube and arranged longitudinally thereof to assist in conducting heat from the flame to the illuminant within the body, and having a part extending over the projecting end of the wick tube. The member is hollow, so that it conducts air to the flame to assist the combustion.

The object of the invention is to provide a simple, inexpensive and light weight miners lamp, which is compact in form, which is adapted to burn wax or the like as an illuminant, in which the combustion of the wax or other substance is complete, and which thus obviates the production of smoke and other noxious gases.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings formin a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which Figure 1 is a longitudinal section of an embodiment of my invention; Fig. 2 is a plan view of the wick tube; Fig. 3 is a perspective view of the member removably mounted upon the wick tube; Fig. 4 is a transverse section on the line H of Fig. 1; and Fig. 5 is a perspective view showing a part of the lamp body, a part of the spout, the projecting wick tube, and the member mounted thereon.

Before proceeding to a more detailed explanation of my invention, it should be clearly understood that while the same is particularly useful as a means for employing wax and the like for producing a light, any other illuminant such as oil or petroleum can be equally well employed. If wax is used, it is necessary to provide means for transmitting heat from the flame to the main body of the wax, in order to liquefy or soften the same, to enable the wick to draw the wax to the point of combustion by capillary action. In my lamp, a member is mounted upon the wick tube and extends longitudinally of the same; it is fashioned from metal or other heat-conducting material for the above purpose. The member is hollow, and has wings or other parts extending over the projecting end of the wick tube and serves as an air conduit for supplying the flame with sufficient air to insure complete combustion, thereby obviating the production of smoke, carbon and noxious gases. This feature is of great importance, especially if the lamp is to be used in poorly ventilated mines where such gases are often a source 'of danger to the workers in the same.

Referring more particularly to the drawings, I prefer to provide the lamp with a cylindrical or slightly tapered body 10, fashioned from sheet metal and having a hinged lid or cover 1 of any suitable form. The body has a hook or hanger 12 by means of which the lamp can be removably attached to the cap or some part of the clothing of the user. Preferably, at the side remote from the hanger, the body has a tapered spout 13, communicating interiorly with the lamp body through a suitable opening 1 1, in the wall of the lamp. The shape of the body permits shaved wax or the like to be easily introduced into the same. I have shown in the type of lamp illustrated herewith, for example, a liquid illuminant 15 such as oil or the like. The spout 13 has an opening 16, through which projects an inclined wick tube 17, which extends into the body and has its lower end near the bottom of the same. Preferably, the wick tube is flat, to receive a correspondingly shaped wick 18, which I have found to be'particularly advantageous in connection with a lamp for burning wax. The wick has the lower end shredded to provide a complete contact with the illun1inant. Furthermore, near the lower end, the wick tube has an opening 19 through which the illuminant can enter the wick tube. At the projecting end, near the spout, the wick tube has cut away portions 20 forming outwardly disposed spaced flanges 21 A member 22, preferably of Usection, has at the opposite sides near one end, outwardly extending lugs 23, adapted to be slidably positioned under the flanges 21, to hold the member removably in place. The latter has shoulders 24:, adapted to engage at the end of the wick tube to limit the movement .of the member when it is being inserted in position between the flanges 21. Owing to the U-form of the member, it constitutes an air tube or conduit so that air can pass from a point remote from the flame to the flame. Furthermore, the member has wings 25 ex tending over the end of the wick tube and slightly spaced therefrom, so that these wings are located in the flame when the lamp is lighted. The member thus becomes heated and serves to transmit heat along the wick tube toward the illuminant within the body.

It will be understood that the member 22 may be of any suitable form, and that the wings 25 may be replaced by other parts adapted to project into the flame, or for a like purpose. Near its outer end, the wick tube has openings 26, for the purpose of admitting the air to the wick to assist in the combustion and to allow the wick to be adj usted. The m mber 22 serves a like purpose as has been explained above, and thus the. flame is provided with sufficient air to insure substantially complete combustion, thereby minimizing the production of smoke, soot or the like.

Having thus described my invention 1 claim as new, and desire to secure by Letters Patent:

1. A miners lamp, comprising a body, a wick tube projecting from said body and having a flange, and a heat conducting member mounted upon said tube and having a part extending over the end thereof into the flame, said member constituting an air conduit, and having a lug removably engaging said flange.

2. A miners lamp, comprising a body, a wick tube projecting from said body, and an air conducting member mounted upon said tube and arranged to feed air into the flame teams of said tube from said flame toward said body, and having a part disposed transversely across the end of said tube.

4. A miners lamp, comprising a body, a spout, a wick tube projecting from said spout, and a member removably mounted upon said tube and having a passage therethrough, said member further having a wing extending transversely over the end of said tube.

5. A miners lamp, comprising a body, a spout, a wick tube extending from said body through said spout and projecting from the latter, said tube having oifset flanges, and a hollow member having lugs adapted removably to engage under said flanges and having a shoulder adapted to engage at the end of said tube, said member having a wing extending over the end of said tube into the flame.

6. In a miners lamp adapted to burn wax, a flat wick tube adapted to receive a flat wick, said tube having openings near the ends thereof, and a member removably mounted upon said tube and having a Wing projecting over the end thereof, said memher being hollow to serve as an air conduit,

and being fashioned from a heat-conducting material. 7

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
