VAPOR-LAMP.

To all whomit may concern:

Be it known that I, Bonner A. As'rLnY, a citizen of the United States, residing at Lansing, in the county of Ingham and State of Michigan, have invented Certain new and useful Improvements in VaporLamps, of which the following is a specification.

My invention relates to table lamps for burning gasolene vapor or other similar combustible, and its purpose is to make a lamp that shall be readily moved from place to place, in which the working parts shall be covered and protected from injury and which shall be easily lighted, without removing the shade. I attain these purposes in the device illustrated by the accompanying drawings in which the figure represents a vertical section of my device through the center of the operating valves.

Referring to the drawings, 1 is the main body or tank of my lamp, which is adapted to be partially filled with gasolene or other similar combustible through a filling tube 2, which is kept closed by a cap 3, in which is an opening l, to permit air to be pumped into the tank by any suitable means to create a pressure by which the gasolene is forced upward through the tube 5 to the burner 6. The opening a is closed by a plug valve 7, and the tube 5 is closed by the cock 8. The tubes 2 and 5 are placed close together as shown in the drawings and the tube 5 is angled at 10 so as to bring all the working parts of the device into a space small enough to be readily grasped by the hand. A tube 9 is mounted on the top of the tank 1, inclosing the tubes 2 and .5 and serving a handle by which to carry the lamp, and as a covering for the working parts. A sliding tube 11 is mounted on the upper end of the tube 5 so as to slide freely and is provided near its upper extremity with a slot 12 adapted to receive a pin 13 so as to retain the tube 11 in a raised position when desired, as shown by the solid lines in the drawings. The upper part of the tube 11 is also provided with a generating cup 14 into which alcohol, gasolene or other combustible may be poured for the purpose of heating the tube 5 to generate vapor for burning. The lower part of the tube 11 is enlarged into a bell 15 the lower extremity 16 of which is adapted to fit over the upper edge of the ring 9 as shown by the dotted lines in the drawing, thus completing the Specification of Letters Patent.

handle, and also the covering of the working parts. lVhen in this position, all the working parts of the device are completely covered, and appear like an ordinary handle or support by which the lamp can be carried around. In order to generate vapor for lighting, the cup 14 is filled with alcohol or gasole-ne While still in its lowered position; it is evident that this may be done without removing the shade and with great ease because of the lowered position. The liquid in the cup is then ignited and the bell 15 is raised to the position as shown in the solid lines in the drawing and supported on the pin 14c. The flames rise about the tube 5 and against the burner 6 and generate vapor. The cock 8 is then opened and the lamp lighted. The complete burner, itself, is not shown in the drawing, as any approved form of burner may be employed. When generation is completed and the lamp lighted, the tube 11 is released from the pin 13 and let fall into the position shown by the dotted lines in which position it remains while in use. When it is desired to put outthe lamp, the tube 11 is raised so as to expose the valve 8 which is then closed and the lamp goes out. If it is desired to put in new gasolene, the cap 3 is removed and gasolene poured in in the ordinary manner through the tube 2. To pump in air. the valve 7 is opened and the air pumped in by any suitable device for that purpose, for instance, an ordinary bicycle pump. The valve 7 is then closed so as to retain the air pressure. Additional strength is given to the main body of the device by a bolt 17 but this forms no essential part of my device and may be omitted if desired.

I claim as my invention and desire to secure by Letters Patent.

1. In a vapor lamp, in combination, a generating tube provided with valves, and a cover adapted to slide freely on said generating tube and conceal said valves.

2. In a vapor lamp. in combination, a generating tube provided with valves; a cover adapted to slide freely on said generating tube and conceal said valves, and means for retaining said cover in a raised position.

3. In a vapor lamp. in combination, a generating tube provided with valves; a cover adapted to slide freely on said generating tube and conceal said valves; a generating cup mounted on the upper part of said cover, and means for retaining said cover and cup in a raised position.

4. In a vapor lamp, in combination, a tank adapted to contain a combustible liquid and compressed air; and also to serve as a support for said lamp; a tube opening into said tank and provided with means for in troducing air and combustible into said tank and for retaining the air pressure; a second tube having one extremity opening into said tank nearly at the bottom and a burner at the other extremity and provided With a valve for regulating the flow oi liquid, said second tube being placed in close juxtaposition to said first tube so that the Whole Will occupy only a narrow space; a cover adapted to slide on said second tube and cover both the said tubes and valves, and releasable means for retaining said cover in a raised position.

In testimony whereof, I affix my signature in presence of two Witnesses.
