1'0 aZZ whom it may concern.-

Be it known that 1, JOHN EDWIN FoxLEE, a subject of the King of Great Britain, residing at Grays Hill, Billericay, Essex, England, have invented certain new and useful Improvements in Oil-Lamps, of which the fol lowing is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to oil-lamps, and particularly to what are known as chandeher-lamps; and the invention consists in certain improvements in lamps of this class whereby the same are rendered more efficient for heating and illuminating purposes.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a central vertical sectional view of a chandelier oil-lamp embodying my in vention, and Fig. 2 a section on the line 2 2 of Fig. 1. i

In the practice of my invention I provide a suitable oil tank or vessel a, through which is passed a central vertically-arranged tube 1), and a suspending hook, link, or similar device c is connected with the upper end of the tube b above the tank or vessel a, by which the device or apparatus may be suspended in the manner of an ordinary ohandelier-lamp.

The tank or vessel (1 is provided in the top with a filling-opening, which is closed by a screw-threaded plug d, and the tank or vessel a is provided at the bottom with a socketsleeve 6, through which the tube 1) passes, and the tank or vessel a at the top and bottom thereof, where the tube 1) passes therethrough, is made oil and air tight. The tube b extends downwardly below the tank or vessel a, as shown at b, to any desired extent, and connected with the lower end thereof is a coupling f, the lower end portion of which is enlarged and in which is placed a packing f, and into the lower end of the coupling f is secured a tubular member or nipple f and the parts f and f form a packing-box suspended by the tube 1) or the lower end portion 6 thereof and through which is passed a tube g. The tube 9 is vertically movable through the packing-box formed by the parts f and f 2 and in the lower end portion 5 of the tube 1), and the upper end of the tube g is enlarged or made bell-shaped or provided with an annular collar or flange 9 so as to prevent it being drawn out of the tube I) or through the coupling and packing-box members f and f and the member f is provided with an inwardly-directed annular shoulder at g to aid in accomplishing this result. A coupling 9 provided with a valve 9 is connected with the lower end of the tube g, and a tube h is secured to the lower end of the coupling 9 and said tube h is secured in the bottom of a receiver i, as shown at W. The lower end of the tube h is provided with an enlarged member 7L which extends upwardly about twothirds of the way through the receiver 41, and in the bottom of the receiver is a reduced chamber 1?, through which the lower end portion h of the tube h passes, and the lower end portion of the tube 72, is provided with a port or passage 76, which communicates with the reduced chamber i of the receiver i. Connected with the bottom portion of the receiver i and communicating with the reduced chamber 1' are tubular arms Z, any desired number of which may be employed and each of which supports a lamp comprising a reservoir m and a burner m, and the receiver i is preferably provided with a transverse screen j, which is designed to keep dirt, dust, and other foreign substances out of the oil in the bottom portion of the receiver and to aid in preventing the evaporation of said oil.

It will be observed that the port or passage lc is at and slightly above the level of the tubular arms Z, and the tube 1) is provided at the bottom of the tank or vessel a with a small port or passage, and near the top of said tank or vessel is a similar port or passage I).

' In the operation of this apparatus the tank or vessel a is filled or partially filled with oil, and the valve gr being opened this oil will flow from the tank or vessel a through the port or passage b down through the lower end portion 1) of the tube 1), through the tubes 9 and h, and out through the port or passage 7c in the reduced chamber i in the bottom of the receiver i, from which it will flow into the reservoirs m. It will be understood that the oil cannot rise in the receiver i above the top of the port or passage 7c or above the top of the reduced chamber 11 in the bottom of said receiver, and in order to permit of the flow of oil to this extent the air passes in through the port or passage 76, up through the tubes h, g, and b, and into the l tank or vessel a through the port or passage b and in this way the flow of oil into the lamps or burners is controlled and regulated by atmospheric pressure.

It will be understood that the part b of the tube 1) and the tube g are telescopically connected, and the receiveri, with the arms Z and reservoir-lamps m, may be raised and lowered by moving the same upwardly or downwardly, and in the form of construction shown the friction between the tube g and the parts f and f 2 is sufiicient to hold the receiver 'L, arms Z, and reservoir-lamps m at any desired point of adjustment.

It will be understood that the oil in the reservoirs m may be used for heating purposes as well as for illumination, and my invention is not limited to any particular use of the apparatus herein described, and various changes in and modifications of the construction herein shown and described may be made without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an oil-burning apparatus, a closed tank adapted to be suspended from an over- 5 head support, a tube passing vertically through said tank and provided therein and near the top and bottom thereof with ports or passages, a supplemental tube telescopically connected with the lower end of the tank-tube, a receiver connected with the lower, end of the supplemental tube, and latorally-directed tubular arms connected with said receiver and provided with burners, said supplemental tube being also provided within the bottom portion of said receiver with a port or passage, substantially as shown and described.

2. In an oil-burning apparatus, a closed tank adapted to be suspended from an overhead support, means for filling the same, a

tube passed vertically therethrough, said tube being extended below the bottom of the tank and provided with a packing-box, a supplemental tube passing upwardly through said packing-box and into the lower end of the first-named tube and movable in said tube and packing-box, a receiver connected with the lower end of the supplemental tube, lateral tubular arms connected with said receiver and provided with burners, and means for controlling the flow of oil from said tank into said burners by atmospheric pressure, comprising ports or passages in the tube which passes through the tank at or near the top and bottom thereof, and a port or passage in the bottom portion of the tube which is connected with the receiver, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 28th day of November, 1905.

JOHN EDWIN FOXLEE.
