IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent No. 12,998, dated May 31, 1864; antcdated March 23, 1864.

To all whom it may concern:

Be it known that I, ANDREW J. RITTER, of the city of Rahway, county of Union, and State of New Jersey, have invented a new and improved mode of lighting coal oil and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, figures and letters of reference marked thereon.

The nature of my invention consists in providing a coated lamp with a perpendicular vented tube or cylinder, which is incased within a short chimney or globe, the globe being raised or lowered by a slide which encircles the cylinder, the whole being arranged for the purpose of lighting the lamp without taking off the chimney or globe, and for producing a strong draft with a short chimney or globe, thereby doing away with the long chimney heretofore used.

To enable others skilled in the art of using lamps, and to make and use my improved lamp, I will describe it in the following spot-1 fication and drawings annexed thereto, which form a part of the same, reference being had to the figures and letters marked thereon.

The same letters and figures refer to the same parts in all of the drawings.

\Vith the usual fixtures for burning coil-o 1 it is very necessary, when lighting the lamp, to remove the chimney, and when the lamp is lighted to replace the chimney again. It is also necessary to have a long chimney to create sufficient draft to bring out a bright light; and hence the chimneys are often broken by heat or otherwise. Now, the object of my invention is simply to provide a more convenient method of lighting these lamps, and at tLe same time produce a bright light and save breaking of chimneys, which is incident to old devices.

Instead of using the long chimney, as above described, I use a short chimney or globe, in combination with other parts, in the following manner: 1 take, in place of the part which is generally used for the stem or pedestal of what is termed a high lamp, and form, in place of it, a tube or cylinder, as shown at B, Figure 2. This tube or cylinder B is constructed of sheet metalsay about one inch in diameter and three inches long. At the lower end of the cylinder B, l perforate it snflicientto admit the air to pass in freely above the bottom piece H, as at I) Z), Fig. 1, and by this mode of passing the air in through the cylinder I get a good portion of my draft to the flame. To get my wick and flame to the top of the cylinder B, I form a tube of sufiicient length to reach to the top, as shown at E, Fig.1. The tube E is formed the same as other flat tubes, except being a little larger at the bottom, making it of a tapering form, as shown from c y e, so that the wick is allowed to remain loose and free from pressure within the tube, allowing the oil to ascend freely to the flame, which passes through the cone at the top in the usual manner. The spindle and spurwheels F ff, for raising and lowering the wick, and the tube E and bottom part, H, are all fitted and fasteiud to the bottom of the cylinder B in the usual manner, as shown at E, F, and H, Fig. 1. I now construct out of suitable metal the slide 0, as shown at Fig. 5, and place it upon the cylinder B, as at Fig. 2, the slide 0 being so constructed with prongs J J J J, or otherwise, that it will hold the chimney D securely, as at Figs. 3, 6, and 7. I then place on each side of the cylinder B, and directly opposite to each other, wire springs formed similar to umbrella-handle springs, as at I I, Fig. 2, and the springs I I, being so arranged thatwhen the slide 0 is pushed up and over them they will catch and hold the chimney I) up in its proper place, as at Figs. 3 and 7. Fig. 3 shows the whole arrangement, which can be attached to any lamp by means of the screw part II, which makes the arrangement complete for operations, as at Figs. 6 and 7. Now, when the lamp is to be lighted it is only necessary to press in the springs I I and lower the chimney or globe l), as at Fig. 6. Then raise or lower the wick by the. usual mode, light the wick at the top, as shown at G g, Fig. 6, then raise the slide 0 until it passes over the springs I I, then the chimney or globe 1) will be brought to itsproper place, as at Fig. 7. When in this position, the draft created by the chimney part .D, combined with the draft created by the cylinder part B, is sufficiently strong to make a brilliant light.

I am aware that there are pirforated and vented cones of various kinds. I do not claim anything of this kind as I use the common cone. I do not claim any particular mode for raising the wick. Nor do I claim any particular substance or dimensions for constructing the parts hereinbefore described.

hat I do claim as myinvention, and desire to secure to me by Letters Patent, is-

The operation and combination of the globe or chimney D slide 0, perforated or vented cylinder B, springs I I, and long and tapering tube E, or their equivalents, for the several purposes herein substantially set forth and specified.
