MINERS LAMP.
Specification of Letters Patent.
Patented Feb. 15, 1910.
Application filed. November 18, 1909. Serial No. 528,753.
To all whom it may concern:
.be it known that we, Tuorms I). .\'lb, of W inburne, in the county of (llearlield and State of Pennsylvania, and Ronnn'r F. MON- TEITH, of Patton, in the county of Cambria same State, both citizens of the United States, have invented certain new and useful Improvements in Miners Lamps, of which the following is a specification.
Our invention relates to lamps used by miners and has for its object the provision of a lamp constructed to burn the solid fuel in general use.
To this end our invention consists in providing in combination with the ordinary spout lamp, heretofore used, an inner tube holding the wick and formed with perforations to supply the wick with fuel, and a copper plate in the bottom of the oil receptacle or on having copper wires secured thereto anc' extending between the spout and its inner wick tube and outside of the lamp where the flame will strike them so that the heat therefrom will be conducted therethrough to the plate to melt the cake of oil adjacent to the inner end of the wick to supply it with fuel.
Our invention will be described in detail hereinafter and illustrated in the accompanying drawings in which Figure 1 is a View in elevation of our improved lamp, Fig. 2, a central vertical sectional view, Fig. 3, a cross section of the wick spout, and Fig. 4, a detail view of the heating plate and conductor wires removed from the lamp.
In the drawings similar reference characters indicate corresponding parts in the several views.
The lamp A is of the ordinary construction used in miners lamps and consisting of an oil cup or receptacle B conical in shape and having the wick spout C at one side and the hook D on the opposite side to secure the lamp to the miners hat or cap.
The wick spout in our improved lamp is provided with an inner tube 1 having its outer end much smaller in diameter than the inner end and arranged concentrically with the end of the spout, while its inner end is enlarged in diameter and has its upper portion secured to the inner end of the spout and oil receptacle, where joined, while the lower portion of the inner end is spaced 1 away from the inner end of the spout an appreciable distance to form a passage 2 between the oil receptacle l3 and the space between the spouts and inner tube, said passage being adjacent to the bottom of the lamp for the purpose hereinafter stated.
3 indicates a plate made preferably of copper because of its well known heat conductivc properties and mounted in the lower portion of the oil receptacle B, and 4. copper wires secured to the plate 3 and extended through passage 9 and between the spout C and inner tube 1.outside of the end of the spout and have their outer ends formed with coiled portions 5 arranged at opposite sides of the wick tube. The inner tube 1 is preferably provided with holes 6 to enable the oil to flow to the wick.
As stated above our lamp is designed to be used in burning solid oil which is sold in sticks and which must be melted before it will feed through the wick. This is accomplished by the plate 3 heated by the wires 4: by conduction. In use the lamp is as stated secured to the miners hat or cap by means of the hook D so that the heavy side of the lamp, or the spout, inclines downwardly. For this reason the passage 2 is provided so that the melted oil may flow from the oil receptacle B to the space between the spout C and tube 1 where it will be kept heated by the wires 4, but as the passage 2 is only around the lower portion of the spout the melted oil is retained in the bottom of the oil receptacle or in the spout so that the solid oil in the upper part of the receptacle B will not be melted to a liquid and will operate to prevent the melted oil from splashing out.
Having thus we claim is- 1. In a miners lamp, in combination with the oil receptacle, a plate located in the bottom of said oil receptacle, and a heat conductor secured to the plate and positioned to be heated by the lamp flame.
2. In a miners lamp, in combination with the oil receptacle, a plate located in said receptacle, and wires secured to the plate and extended outside of the lamp and positioned to be heated by the lamp flame.
3. In a miners lam in combination with an oil receptacle, am a wick spout, a plate located in the bottom of the oil receptacle,
described our invention what and a heat conductor secured to the plate portion of the inner end of the spout, the
and extended through the spout to the outer 1 lower portion of the inner end of the wick end thereof.
4. In a miners lamp, in combination with an oil receptacle and a wick spout, a plate located in the oil receptacle, and, wires secured to the plate and extended through the spout to the outer end thereof.
5. In a miners lamp, in combination with an oil receptacle, and a Wick spout, a wick tube secured in the wick spout, a plate located in the bottom of the oil receptacle, and wires secured to the plate and extended between the spout and inner tube and having their ends opposite the end of the wick tube.
6. In a miners lamp, in combination with an oil receptacle, and a wick spout,a perforated Wick tube located in the spout having its outer end secured concentrically of the outer end of the spout and its inner end of enlarged diameter and secured to the upper tube spaced from the spout to form a passage, a copper plate located in the lower portion of the oil receptacle, and copper wires secured to said plate and extended through the passage aforesaid and between the spout and wick tube, the ends of said wires extended outside of the spout on opposite sides of the Wick tube and formed with coils.
In testimony whereof we hereto aflix our signatures in the presence of two witnesses.
