Letters Patent No. 91,141, dated June 8, 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 0. LOVE, of Philadelphia, Pennsylvania, have invented an Improved Lamp-Burner; and I do hereby declare the-following to be a full,

, clear, and exact description of the same.

My invention consists of improvements in coal-oil lamp-burners, fully described hereafter, the improvements having been made with the view of rendering the flame more brilliant, gaining ready access to the wick, and easily adapting the burner to receive chimneys differing in size.

In order to enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation, reference being had to the accompanying drawing, which forms apart of this specification, and in whic Figures 1 and 2 represent exterior views of the two main parts of the lamp-burner, detached from each other;

Figure 3, a vertical section of the same, connected the outer end of ca h of .which bears the point of a set-screw, h, passingthrough the rim e,jas best observed, in fig. 4, and each spring has a finger, '5, pro- 'jecting upward through a slot, j, in the plate a. V

' By operating the screw h; the fingers, over which the glass chimney of the lamp fits, may be so adjusted as to be adapted to chimneys of different sizes. It is not essential, however, that all the fingers '6 should be adjustable, one movable finger sulficing to adapt the whole to difi'erent chimneys.

The portion B of the burner consists of a base, m having the usual screw-projection m, and carrying the flat-wick tube It, and the usual devices for operating the wick.

To this base is a perforated.,cylindrical or slightlytapering casing, n, which is smaller in diameter than the dome, extends upward into the latter, above the wick-tube, and terminates in a flange, 1), which fits snugly in the interior of the dome b, as best observed on reference to fig. 3.

Nctches are cut in this flange, as seen in fig. 5, and these notches are so arranged that two of them, q q, shall be in line with the wick-tube, one at each end of the same.

On the base, m, are lugs t t t, arranged to so fit against the underside of the plate a, and against the interior of the dome, that while they serve to maintain the perforated casingn concentric with the dome, they are such as to permit the portion A of the burner to be readily detached from the portion B.

I have found that the nearer the perforated easing, into which air passes to the top of the wick, is to the flame, the better is the quality of the latter; hence, the placing of the perforated casing 11. within the dome B.

While the flange p, fitting snugly inside the dome,

serves, withthe lugs t t t, to render the upper portion of the burner a steady integral part of the lower portion, the upper portion, with its chimney, can be readily detached when access to the wick is necessary. At the'same time, the notches in the steadyiug-flange permit a plentiful supply of air to gain access to the interior of the dome above the wick, and the air passing through the notches qq 0f the flange, impinges against the edges of the flame, and renders the latter more brilliant.

I am aware that vertical fingers have heretofore I been so secured to a lamp-burner as to be adjustable thereon, and I, therefore, do not claim, broadly, such adjustable fingers. But the devices hitherto used for adjusting the fingers have been complicated, and of such a character as to secure the fingers immovably in their position, after adjustment, thus causing the fracture of the chimney, should it contract.

By the device above described, a ready adjustment of' the finger is effected, the fingers will move freely inward when the chimney contracts, while the cost of manufacturing the burner is not materially increased.

I claim as my invention, and desire to secure by Letters Patent- 1. The flange p, with its notches, at the upper end of the perforated casing n, in combination with the outer cone A and its slot d, all as described.

2. The combination of the springs f, their fingers t, and the set-screws It, all arranged on a burner operat ing as set forth.

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

' JOHN 0. LOVE.
