Letters Patent No. 94,421, dated August 31, 1869.

IMPROVEMENT IN LAMP-BURNERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be'it known that I, JOHN C. LOVE, of Philadelphia, in the State of Pennsylvanimhave invented and made a new and useful Improvement in Lamp-Burn ers; and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification, wherein- Figure 1 is an elevation of the base of the burner, and a section of the cone or cap in a vertical plane, coinciding with the flat-wick tube;

Figure 2 is a section of burner complete, in a vertical plane, transversely of the fiat-wick tube;

Figure 3 is a sectional plan, at the line 3 4 of fig. 2;

Figure 4, perspective view of the capor deflector in section;

Figure 5 is a similar view, the section. being at right angles to fig. 4; and

Figure 6 is an inverted plan of the dome or deflector.

Lamps have heretofore been made with a variety of deflectors for directing the draught of air upon the frame, and in some cases double domes or deflectors are employed.

. The object of the present invention is to direct the edges of the flame so that the same will ascend-vertically, or nearly so, and not be liable to spread and come in contact with the chimney, and at the same time to direct the main portion of the air-draught upon the base of the flame, to flatten it and insure a perfect combustion.

My invention consists in the combination of a deflector, for directing the air to the base of the flame, with a secondary deflector at the cudof the flameslot, for giving an upward direction to the air at the edges of the flame, so as to perfect the combustion and prevent the flame smoking the chimney.

In the drawing- A represents the wick-tube;

B, the ratchet-cap, with the screw (1, for the reservoir;

c is the perforated air-distributer;

I) is the chimney-holder; and

F is the deflector.

The chimney holder may be around the edge of the air-distrihuter, as in fig. 1, or around the edge of the deflector F, as in figs. 2 and 3.

I have shown the deflector F as removable from the wick-tube A, the said deflector F having guides H projecting, as ate 1, fig. 6, to set at each side of the wick-tube, or with grooves, as at f, to take the edges of said wicktube.

The air-space 2', inside the guides H; allows an ascending current of air at these points. In cases, however, where the deflector F is sustained in other or well-known ways, the air-spaces i may not exist.

The upper part 6, of the deflector F, is made with the flame-slot running entirely across the same, so that the sides of the deflector, that at this point are almost performs the two duties of completing the combustion v at the edges of the flame, and of giving to the flame a straight upward direction, and preventing the flame spreading too much.

If the deflector F only were employed, the air would not be sufliciently impinged against the sides 'of the flame, near the basethereof. I, therefore, make use of the dome or deflecting-plates J, below the cap 0, so that by them the ascending current of air is gathered sufiiciently, and directed upon the sides and base of the flame, so as to produce a perfect combustion.

By this lamp-burner, I am enabled to raise the flame in an ordinary cylindrical chimney, contract-ed toward the top, so that the flame will extend almost to the top of the chimney, without the glass being smoked or broken.

I do not limit myself to any particular shape or character of chimney-holder or air-distributer, nor to the construction shown of the deflector F, below the plates or dome J, as these may be of any desired character;

and the upper part of the deflector Fand the domeplates J may be used with any cone, deflector, or draught-plate to which they may be applicable.

It will be evident that the draught deflected by the plates or dome J against the sides of the flame is the primary draught for supporting combustion, and that the ascending draught, at the ends of the flame-slot,

becomes a secondary draught, that prevents the flame spreading too much.

What I claim, and desire to secure by Letters Patent, is-

The deflector F, with a flame-slot extending to the vertical portion of said deflector, or nearly so, in combination with the plates or dome J, to direct the air upon the sides of the flame, the deflector F setting closely around the dome J, substantially as and for the purposes set forth.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

Witnesses: JOHN C. LOVE.
