IMPROVEMENT IN. LAMP-BURNERS.

Speciicatio'n forming part of Letters Patent No. 53,953, dated April 17, 1866; antedated April L', 1866.

To all whom t may concern.-

Be it known that I, PETER CRANs, Jr., of Philadelphia, Pennsylvania, have invented an Improvement in Coal-Oil Lamps; and I do hereby declare the following to be a t'ull,clear, and exact description of the same, reference being` had to the accompanying drawings, and to the let-ters ot" reference marked thereon.

My invention consists of an adjustable tube arranged above the wick-tube, and combined with devices described hereinafter, or their equivalents, so that the upperend of the wick maybe exposed as desired, and so that the tube-is prevented from becoming sutticiently heated to char the wick within the saine.

In order to enable others skilled in the art to make and use my invention, Iwill nowproceed to describe its construction and operation.

On reference to the accompanying' drawings, which form apart of this specification, Figure l is a sectional elevation of the burner of a coal-oil lamp, showing my improvement; Fig. 2, a vertical section on the line 1 2, Fig. l; and Fig. 3, .a plan view.

A is the perforated base of theburner, which may be similar to that of common burners; and B is the ordinary cap or dome, in which is the usual elongated opening a. To the base .A is secured a short wick-tube, b, and near each edge of the latter is a vertical guide-rod, o, on which slides an adjustable wick-tube, b. To the lower end of the tube b is`jointed one end of a curved rod, d, which extends through the side ofthe base A.

The Wick O is passed through the tubes b and b', and is so adjusted that the upper end may be atthe proper distance from the top of the cap, when the lamp may be lighted and burned in the usual manner.

Should it be found that too much of the Wickis exposed, so as to cause the flame to smoke, the outer end ot' the rod d should he depressed so as to raise the tube b', and thereby cover aportion of the Wick before exposed but iff'the tlame is too small the tube b is depressed by elevating the rod d, so as to expose a greater portion of the wick.

In burners ofthe ordinary construction the wick-tube is liable to become so heated as to char the wick Within the upper portion ofthe same, in which case it is necessary to remove the Wick in order to insert a new one or to detach the charred portion.

It will be seen that in the above-described burner the upper tube, b', is so small and so exposed to the fresh air admitted into the burner that it lcannot be heated to such an extent as to injure the wick. As there is no connection between the tube b and the burner, except through the medium ot' the rods c 0 d, the heat imparted to the tube cannot be conveyed to the burner. The latter is consequently maintained much cooler than in lamps of the usual construction.

I do not desire to claim, broadly, the use of an adjustable tube for regulating the flame by exposing more or less ot' the Wick, as such a device is shown in the patent granted to M. B. Vidal, July 30, 1861; but

I cla-im as my in vent-ion and desire to secure by Letters Patent- 'Ilie adjustable tube b', arranged above the Wick-tube b, and combined with the rod d and guide-rods c c, or their equivalents, as and for the purpose set forth.

In testimony whereof I have signed my name to this specification iu the presence of two subscribing Witnesses.
