IMPItOVBMENT IN LAMP-BURNERS.

TO ALL WHOM IT MAY` CONCERN:

Be it known that I, GEORGE SMITH, of Providence, in the county of Providence, and State of Rhode Island, have an Improvement in Lamp-Burners; and Ido hereby declare that the following is a full, clear, .and exact description thereof, reference being lhad to the accompanying drawings, making a part of this specification, in which- Figure 1 is a side view of a lamp-burner having my invention applied to it.

Figure 2 is a section taken in the horizontal plane indicated by red line :e :t in iig. 1.

Figure 3 is asimilar section showing the sliding valve open.

Similar letters of reference indicate corresponding parts in the three figures.

This invention relates to an improvement on lamp-burners which have holes made through their .sides for allowing of the lighting of the wicks without removing their chimneys. The nature of my invention consists in having such holes closed by sliding valveswhich are acted upon by springs so that they'will keep closed except when the valves are held back by the fingers during the act of lighting the lamps, as will be hereinafter described.

To enable others skilled in the art to understand Iny invention I will describe its construction and operation. In the accompanying drawingsl A represents the' body of a common form of lamp-burner of a lampl requiring the use of a chimney or a cone, B. C is the wick-tube of this burner,and .D is the thumb-button on the-outer end of thcstem of the wick-adjusting spurs. An opening of asuitable size is made through the body of the burner below the base of the cone B for the purpose of admitting of the introduction of a lighted taper for lighting the wick. This hole is provided with a sliding valve, a, applied inside of the burner, which valve is attached to. a button, b, that slides laterally in an oblong slot, c, and projects from the outside surface of the burner a suiiicient distance to he pressed upon by the thumb when it is desired to open the aperture leading into the burner. The neck andv collar of this button Z1 form a means for attaching the sliding valve a to the burner, as shown r in gs. 3 and-4. i I

Sliding valves or gates have been used before my inventionfor closing the openings made in lamp-burners for lighting the lamps-without removing the chimneys, but the objection has been that such -valves do notA remain closed, and consequently allow a too free admission of air, so that the lamps'smoke.

It is desirable to have Aopenings in lamp-burners which will allow of the lighting of the wicks without removing the chimneys, and to remove the abovementioncd objections I apply a spring, g, to the sliding valive a, as shown iu gs.- 2 and 3, which, when this valve is unrestrained, will keep it closed firmly against the pin z'. The button b on 'the valve a is arranged in such relation to the button D that this latter will serve to afford a purchase for the ngers to allow of the drawing back of the valve a with one hand without liability of upsetting or tilting the lamp, while with the other hand the taper can be introduced through the opening to light thewick. The manner o1n opening the hole through the side of the burner with one hand is illustrated in fig. 3, which represents the valve or slide drawn back. I

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is 1. The application of a spring to the slide or valve a, which is used for closing the openingthrough a lain-pburner, substantially as described. i 2. The relative arrangement ot' the laterally movable spring slide a with respect to the wick-spur button D, substantially as described. i
