Application filed October 12, 1912. Serial No. 725,498.
To all whom it may concern:
Be it. known that I, JOHN MAJER, a citizen of the United States, residing at Lis'tie, in the county of Somerset, and State of Pennsylvania, have invented certain new and use ful Improvements in Lamps; and I do here-- by declare the following to be a full, clear, andexact description of the invention,such
. as will enable others skilled in the art to made a part ofthis application,
which it appertains to make and use the same. I r
Thislinvention rel ics to lamps, and-"it relates more particularly to an improved formof miners lamp.
An object of the invention is to provide an improved oil burning lamp tobe used by miners, for the purpose of guarding against accidents from sparks. v
Another object of the invention is to provide a lamp having a reflector mounted in hinged relation to the main body of the lamp so that said reflector .can quickly and easily be cleaned.
' Other objects and advantages may appear hereinafter and in the claims.
In the accompanying drawings which are liigure 1 is a side elevation view of my improved miners lamp. Fig. 2 is a vertical sectional View through the damp, the burner being in elevation, and, Fig. 3 is a front elevation of the lamp.
Referringtothe drawings in which similar reference numerals designate corresponding parts throughout the several views, the reference character 5 designates the reservoir or tank, for holding kerosene or any suitable. liquid fuel, and to this reservoir is I secured, by any proper means,as by screw tion, carrying a wick 8. burner 7 1s a; cyllndrical combustion chamthreads 6, a burner 7 of ordinaryaconstruo' SecuredE-on the her 9, having an aperture 10 through its lower convex surf-ace, the burner extending the combustion chamber, and communicating therewith, is the perforated crown 11,
stationed concentrically above. the burner 7.
rial, which is held in place by means of a radially and inwardly extending flange 13, formed on a retaining ring 1 1, said retaining ring being secured on the combustion chamber or cylinder, by proper means, as indicated b the screw threads 15. I may provide a at ring 16, for holding the transparent disk 12 within the ring 14 when the latter is removed from the cylinder, but it is obvious that this ring may be dispensed with if desirable. The rear end of the cylinder is closed by means of a concavo-convex door 17, hinged at 18 to the lower part of the cylinder, and provided with a latch and keeper,
of any proper design, preferably a spring reflector. 20 is snu ly and' securely fitted into the'concavity o the door, in such relation to-the flame from the burner, that the light from said burner is focused approximately at the summit of the flame from the burner. It will be understood by those familiar with the art that these focused rays of light will be condensed, or intensified at this point, and will tend to cross each other, but this tendency will be resisted to a considerable extent, so that theintensified or accumulated light rays will .pass approximately centrally through the transparent element 12, and while this transparent element will reflect the rays to some extent, the focusing effect will obtain to such an extent that a very large per cent. of the light, generated by the burner, will be concentrated within'working reach of the miner or user of the lamp. into thecombustionchamber through said -1 U aperture.v .Mounted or formed on the top of T The apertures 9 provide inlet openings for air, while the apertures in the crown 11 provide outlet openings for the products of combustion, and it will be seen that the passage gf air between'the lower and upper apertures, constitutes an uninterrupted draft, which is slightly deflected inward, or concentrated by the flame, and then passes in a yertical direction into the crown 11 and out of the outlet aperture, carrying the smoke and soot therewith. It Wlll therefore be seen that the reflector 20 remains com aratively free from soot and smoke, so t at its maximum efiiciency is obtained.
Hinged onto one side of the cylinder 9 is a trap door 21, a sprin catch 22 being provided for holding the door 21 normally closed, and by means of this door, the miner may relight his lamp without removing the same from its support. In thus repeatedly relighting the lamp, it occurs that the reflector 20 becomes smoked, owing to imperfect draft and incomplete combustion, and so it is desirable to have eas access to the reflector for cleaning and polishing the same. This easy access is provided by means of the construction shown in which the door which carries the reflector plate may be swung open; whereupon, easy access to the reflector and to the interior surface of the c linder and of the crown is attained; so t at light is reflected from the concave wall of the cylinder, as well as from the reflector. The importance of keeping thecrown free from soot is obvious, for the purpose of keeping the apertures thereof open, and thereby to provide a perfect draft through the combustion chamber. By hinging the door 14 at the bottom, it will be seen that the hook 19 would not become disconnected, but would still retain the lamp in approximately vertical position, even if the catch 18 should become disengaged.
While I have described a lamp of simple construction it will be seen that I have provided one that is thoroughly practicable and eflieient, and one that ehminates the danger of falling sparks'or coals, in a perfectly obvious manner.
Iclaim: I
1. A lamp com rising a horizontally disposed cylindrical ody having a transparent end, in combination with a burner prQ ecting centrally into the bod a concavo-convex door at the end of the body opposite to the transparent end, a hinge connecting the door at its bottom to the body, a latch at the top of the door, a reflector on the inner concave surface of the door, and a supporting hook secured, point downward, to the outer 'convex outside of the door.
2. A lamp providing a horizontally disposed combustion chamber having openings located centrally in its upper and lower sides, a burner secured in the lower opening, a crown secured in the upper opening, the walls of said crown being provided with a plurality of perforations therein, the lower side of said combustion chamber provided with a series of rows of perforations therein concentric with said central opening therein, and in vertical alinement with said crown Whereb air may be admitted directly into said combustion chamber and burnt gases be exhausted directly through said crown.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
