IMPROVED LAM P-B'U RN ER.

Specification formingpart of Letters Patent No. 34,742, dated March 25, 1862.

To all 20700722, it may concern.-

Be it known that I, J. D. OUsTER, of Norristown, in the county of Montgomery and State of Pennsylvania, have invented anew and Improved Lamp-Burner; and I do hereby declare that the following is a full and exact description thereof, reference being had to the Figure 1 is a perspective view of my lamp. Fig. 2.is a side View of the regulating-eap,

andFig. 3 is a top View of. it.

To enable others to make and usemy invention, I will proceed to describe its construction and operation.

The letter A, Fig. ].,is the body of the lamp.

This I make as they are usually made.

', B is the burner. I construct it of brass or any suitable material. It is made to'suit old lamps, and. has a male, screw on the lower end of it, below B, which screws into the tomale screw on the lamp, but the top of it I make from two to six inches wide, aeeordin g to the quantity of light desired.

. Along the top I leave my burner open about one-eighth of an inch, more or less, to suit ,the'wick intended to be used- The thinner the wick and flame the more complete the combustion of the oil will be and the greater the quantity of light will be from a given" quantity of oil. Therefore I make the wick, tube, or burner as thin and as little open along the top and use as thin a wick as will draw up the oil, so as to produce an intense white light and complete combustion of the oil. I I also use a great number of single wicks with success.

I make my burner on a regular bevel on each side and back and in front from the wick-wheel 0 down, so as to make it come round at the bottom, where the male screw is formed on it. This gives me room forthe wick to foldup below the shaft of the wickwheels and run down into the lamp. As the shaft of the wick-wheel draws up the wick it flattens it out at the top in a perfect manner.

C is the wick wheel and shaft. I make it of'brass or iron wire or any Suitable metal.

I cut the shaft with an engraver or suitable tool, so as to raise sharp raspshaped teeth on it, which take hold of the wick or wicks and move thenr up or down. This wick-shaft must fit close in the sides of the wick-tube to prevent the gas and smoke from getting out. I put a washer and pin on the small end of said shaft to keep it in place.

The burner or wick-tube must be as much .open as to allow the wick to pass the wicksha'ft freely, so as to enable the wick-wheels to move it up and not obstruct the flowing of The upper edge of said bu rner should the 011. be beveled off, so as to allow the air to strike the wick as low down as possible for complete combustion. When I use a number of small wicks or threads, I observe the same principle. p

' D is the shade-tube. I form it out of one piece of metal. The 'part D is cut wide and formed into a square tube, and the narrow ends are bent round and soldered to the burner or wick-tube.

E is the shade-spring. I construct it outot' one piece and solder it to the shade-tube above I). On the shoulder, below E,'of this spring the sh ado-stem restswhen in its proper position for use; but for moving the lamp about and for a night-lamp the shade is let down, so as to protect the flame from the wind. For this purposethe spring E is used, and by pressing the spring to the left the shade is left down for said protection.

The flame of my lamp is easily blown out, and I find the shade very useful in order to protect it and to p roteet the eye from its brilliant light.

I make my shades out of tin or sheet-iron or any other metal, and paint them' white inside, if necessary; and I rivet a'square stem to the inside, so as to fit-the shade-tube D.

,The shade must .be made in the shape of a screen, open attop and bottom to let the heat I 011e, two, or more sepalate jetsorflam es along the top of the burner to .diminish the light 1 without putting down the wick too low, as it goes'oiit too easily when 'it'is low down., Byv

theiise of said regulating-cap with one small hole in it my wide burner is conveniently formed into fillight-lllnP, which will: burn but little oil, and with the shade let down over it the wind will not extinguish it.

In my experiments I have found that a, three-inch burner, as shown in Fig. 1, burns 110 more coal-oil than :the small glass-chima light.

. ney lamp, and it makes as bright and steady My object in inyenting said lamp is with, 'nish a burner to burn keroeene or carbon oil vwitheixt a chimney, and I believe I have sileceeded. I also believe the above-lamp will burn other impure oils without a, chimney.

I disclaim the wide wick as such, as it is 'old' and well known. i

What I claiin as my'iinvention, and desire to seen re by Letters Patent, is 1. The bevel lamp-wick tube B and the 'nlode of folding'up the wide wick '01- wicks below the wick shaft C, substantially as de- ;sc1 ibed and shown.

2. The shade-tube D audits spring E, one

orboth to be used on my burner or not, as desired, s1ibstantia1ly as described.

- 3.; The .regulatin cap- F, to be used on my said burner or not, ais desired, substantially "as described andshown I J. D. GUSTER.
