LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 370,516, dated September 2'7, 1887.

Application filed March 19,1886. Serial No. 195,775. (No model.)

To aZZ whom it may concern.-

Re it known that we, Lnwrs J. Arwoon and WILLIAM F. LEWIS, of Waterbury, in the county of New Haven and State of Connectiout, have invented an Improvement in Lamp- Bfirners, of which the following is a specification.

This improvement relates to that class of Argand lamps in which a large flame passes IO up around the button or fiamespreader, and the wick is a flat wick passing up into the round Argand wick-tube.

Our present improvements relate to that combination of parts, hereinafter described,

I 5 whereby the burner is rendered more reliable in its actions and the risk of smoking is materially lessened.

In the drawings, Figure 1 is a vertical section of the lamp-burner complete. Fig. 2 is a plan of the wick-raising devices, the parts above the same being removed. Fig. 3 is a separate elevation of the flame-spreader and its skirt, the supporting-stem, the valve, and the inverted conical distributer. Fig. 4 is a separate section of the air distributer and chimney-holder.

The burner base is provided with a screw, 1, adapted to fit the reservoir-collar, and from this rises the flaring air-distributor 2. The

0 Wick-tube 3 is permanently fastened at its lower end within the screw 1, and the air-tube 4: is connected with the wick-tube by one or two lateral inlet-tubes, 5,that open through the airtube and wick tube, respectively. Usually,

3 5 there will be two of these lateral inlet-tubes, so that the Argand wick will be composed of two flat Wicks brought up together into the form of a cylinder between the air-tube and the wick-tube.

0 Upon the outside of the wick-tube is the shaft 7, that carries the wick raisers 6, that pass through slots in the wick-tube. Theshaft 7 is supported by the air-distributer 2 at the upper portion thereof. The second wick-raisers,

4 5 10, are upon a shaft, 11, passing through and supported by the air-distributer. These wickraisers 10 act through slots in the wick-tube 3 upon the wick to raiseor lower the same, and

. there is a secondary shaft, 12, passing through the air-distributer and through the strap 8, and it is provided with a pinion, 14L, gearing into another pinion, 15, on the shaft 11. The secondary shaft is used for reversing the direction of rotation, so that the wicks at both sides of the airtube may be raised byturning 5 both buttons in the same direction. When forcing down the wicks,both buttons are turned in the same way, but in the direction opposite to that made use of in raising the wicks.

It will be understood that as the wickrais- 6 ers are at opposite sides of the wick, to raise the wick one of the wick-raisers and shafts has to be turned in one direction and the other in the other direction. If the button were di-' rectly upon the shaft 11, it would often be turned the wrong way. The gear-wheels and secondaryshaft 12, with its button, allow this shaft 12 and its button always to be rotated in the same direction as the shaft7 when raising or lowering both wicks. The wick-raising 7 wheels have teeth that are at an inclination to the wheel, so as to occupy radial positions to the air-tube where they enter the wick; hence they act much more efficiently on the wick than the wick-raisers with teeth that are in a a plane at right angles to the wick-raiser shaft.

The flamespreader 18 is upon the upper end of the rod 19, and the lower end of this rod 19 is received into a step or opening in the septum 16, and around the rod 19 and connected with the same is the perforated distributer 20, preferably conical and of perforated sheet metal, and the parts are steadied by the spider 23, around the rod 19, and within the conical distributer 20. This distributor 20 is not fastened to the air-tube; but it can be drawn out, together with the valve 22, by the rod 19, and with it any carbonaceous matter that may have fallen into the air-tube is removed, and the inverted conical distributer o 20, extending above the lateral inlet-tubes 5, allows the air entering through the inlets 5 to equalize and pass up uniformly to the flame. The upper end of the conical distributer 20 is sufficiently large to come into contact with the 5 inner surface of the air-tube, so as to be steadied thereby, and all the air to the inside of the flame is obliged to pass through the perforations of the cone, thereby equalizing the same.

The flame-spreader 18 has a tubular socket, 24, surrounding the rod 19, and allowing for its removal, and there is a foraminous skirt, 26, that hangs from the flame-spreader, and its lower end is open and unobstructed and above the upper end of the wick, so that the currents of air passing the air-tube enter the base of the flame and are also equalized by going through the foraminous skirt into the flame.

Above the air-distributer 2 is the ring 27, that surrounds the wick -tube and forms a close connection between the wick-tube and the air-distributer 2. This ring is usually soldered in place, and it holds the wick-raising shafts down into their notches in the airdistributer 2.

The air-distributer 28 and the spring chimney-holder 29 are preferably made in one piece, together with the internal spring-supports,30, that surround the wick-tube and hold the air-distributer and chimney-holder in place upon the same, and within the chimneyholder is the cone or deflector 31, the upper end of which surrounds the base of the flame and preferably rises above the upper end of the wick-tube and air-tube, and the flange of this cone rests upon the upper part of the airdistributer 28 at its junction with the chimney-holder 29.

The chimney-holder, deflector, and air-distributer 28 can be lifted off the lamp for lighting or cleaning.

We are aware that separate wick-raising shafts have been used, and that gearing has been employed to connect these shafts; but there was not any supplemental shaft, as in our improvement. We are also aware that a perforated cone has been used within the airtube; but its larger end was not in contact with the air'tube, and it was liable to become misplaced or bent, and the air to the base of the flame did not pass through the perforated cone. This is rectified in our im provement. In cases where the air to Argand gas-burners has passed up through a central tube into a hollow button or deflector the action of the same is different from that in our improvement, because, with the perforated skirt that hangs from the button, the air that passes up regularly through the perforated cone passes unobstructedly to the base of the flame, and then the supply of air to the higher parts of the inside of the flame is properly regulated by the perforations in the skirt.

We claim as our invention- 1. The combination, in an Argand lampburner, of an air-tube and a wick-tube, an inverted conical air-distributer within and filling the air-tube, a rod for the same, removable with the air-distributer from the air-tube, a removable button having a hanging perforated skirt above the wick and supported by the rod, and a removable deflector and chimneyholder and air-distributer supported around the wick-tube, substantially as set forth.

2. The combination, with the Argand airtube and wick-tube, of an inverted conical perforated distributer the upper edge of which fits the inside of the air-tube, a stem or rod connected to the cone and removable with it from the Argand burner, and a fiame-spreader at the upper end of said stem having the perforated skirt 26, substantially as specified.

Signed by us this 6th day of March, A. D.
