LAMP.
SPECIFICATION forming part of Letters Patent No. 7 66,449, dated Augu 2, 1904. Application filed November 11, 1903- Sarial No. 180,661. (No model.)
To (all whom it may concern:
Be it known that I, JOHN P. .KING, a subject of the King of Great Britain, and a resident of the city of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Lamps, of which the following is a full, clear, and complete disclosure.
The object of my invention is to provide such a construction in relation to lamps mak' ing use of a liquid for furnishing the illuminating means as will enable the height of the liquid in the lamp to be maintained at a substantially uniform level while said liquid is being consumed.
The invention particularly pertains to that class of lamps which burn hydrocarbon oils, such as kerosene, in which a wick of cotton or other fabric is used to convey the illuminant to the point of combustion by means of capillary attraction. In this class of lamps when the oil has become partly exhausted and the level thereof lowered the point of combustion at the top of the wick is relatively so elevated that capillary attraction is not sufficient to keep up a copious supply of oil to enable the lamp to burn with the same brilliancy as when the reservoir is full. My invention is designed to overcome this difficulty.
Briefly, my invention consists in providing compartments or receptacles within the main reservoir of a lamp and means so that as the level of the oil or other liquid used recedes the same may be raised to a level which will cause the oil to flow into the upper compartment and which will give a level substantially the same as that in the main reservoir of an ordinary lamp when freshly filled.
For a full, clear, and exact description of one embodiment of my invention reference may be had to the following specification, and to the accompanying drawings, forming a part thereof, in which- Figure 1 shows a vertical sectional view of the body or reservoir of a lamp with my improvement contained therein. Fig. 2 is a view of a tube or pipe the function of which is to be hereinafterdescribed, and Fig. 3 is a view of another means for performing the same function as the tube and is also hereinafter to be described.
The numeral 1 indicates the outer casing of the body or reservoir of a lamp, and 2 indicates the usual burner attached thereto.
The numeral 3 indicates the usual flanged opening for filling the reservoir and is provided with the usual cap 4, to which is connected the tube 5, forming a part of my improvement. The cap 4 is interiorly screwthreaded and fits about the flanged opening 3, which is also screw-tlu-eaded.
The numeral 11 indicates a tube or passage which forms practically an extension of the flanged opening 3 and communicates at its lower end with the interior of the cylindrical casing 6, forming a chamber closed at its top. The casing 6 is open at its lower end and is provided at its upper end with a recessed or concave top 7, forming a receptacle adapted to contain some of the illuminant and into which the Wick 13 projects. The said casing 6 is provided at its lower end with means to keep it slightly raised from the bottom of the reservoir to allow the passage of the illuminant to and from the interior thereof. A tube 5 passes through and is connected with the cap 4, thereby furnishing an open air-passage to the interior of the casing 6 through the tube 11. The tube 5 extends upwardly from the cap, so as to allow the flexible tube 8 to be connected thereto. Instead of the tube or pipe 8 I may use for the same function the well-known bulb 9 with the projecting flexible tube 10.
WVhen it is desired to put my device into use, the reservoir 1 is filled in the usual manner by pouring the oil in at the opening 3. after which the cap 4 is placed in position. After the lamp has burned for a certain time the original level of the oil in the reservoir will recede, so as to be below the top of the casing 6, whereupon the oil will be consumed from the concaved portion 7 of the chamber 6 until it has become nearly exhausted. When this point has been reached, the tube 8 or the tube 10 is connected with the tube 5, and by forcing air through said tubes the oil or other illuminant will be forced out of the chamber formed by the casing 6 through the bottom thereof, and its level exteriorly of the chamber 6 will be raised until it overflows into and fills the 'concaved portion 7, as indicated by the dotted line 14. in Fig. 1. This operation may be repeated as often as the illuminant in the receptacle or recess 7 becomes exhausted; but it will be noticed that the height of the oil drawn upon by the wick 13 is never lower than the bottom of said receptacle 7, although the oil in the reservoir 1 may be nearly exhausted therefrom. Thus it is thatthe effective height of the oil drawn upon by the wick 8 is maintained practically constant and the illuminating eifect therefrom is undiminished when the oil has reached a low level in the reservoir or body of the lamp.
I do not wish to be limited to the exact form, arrangement, or proportion of parts herein shown, for various changes in detail may be made without departing from the spirit and scope of my invention; but
What I claim, and desire to protect by Letters Patent of the United States, is
1. In an oil-lamp, a reservoir having dividing means within the same, said means separating the said reservoir into upper and lower compartments, there being communication between the lower portion of the lower compartment and the upper portion of the upper compartment and means to allow air to be forced into the lower compartment.
2. In an oil-lamp, a reservoir having dividing-walls within the same said walls separating said reservoir into the upper and lower compartments there being communication between the lower portion of the lower compartment and the upper portion of the upper compartment and means to allow air to be forced into the lower compartment.
3. The combination with the reservoir of a. lamp, a casing therein having a recessed top and forming an upper receptacle anda chamber, said chamber and receptacle having communication with each other, and a conduit connecting the interior of said chamber with the exterior of said reservoir.
4. The combination with the reservoir of a lamp, a casing therein having a recessed top and forming a chamber and an upper receptacle, said casing having an opening at its lower portion, and a tube connecting the upper portion of said chamber with the exterior of the reservoir.
5. The combination with the reservoir of a lamp, a casing forming an upper receptacle and a lower chamber, there being communication between the lower part of said chamber and said receptacle, said reservoir having an opening through which the same may be filled, a stopper for said opening, and a tube passing through said stopper and opening and communicating with the interior of said chamber.
6. The combination with the reservoir of a lamp, a casing therein slightly smaller than the interior of said reservoir and having a recessed top and an opening at its lower portion, and a tube connecting the interior of said casing with the exterior of said reservoir.
7. An oil-lamp reservoir having divisionwalls within it separating it into upper and lower compartments, there being an open passage-Way between said compartments and an opening into the lower compartment for filling the lamp, a stopper in said opening, a pipe passing through said stopper and a tube fitting over .said pipe and means for forcing air through said tube and pipe into the lower compartment whereby oil is forced from said lower compartment into the upper compartment.
In witness whereof I have hereunto set my hand this 10th day of November, 1903.
JOHN P. KING.
