`|MPRovEMENT IN LAMPS.
Specification forming part of Letters Patent No. 165,726, dated July 20, 1875 application tiled May 1,1875.
To all 'whom it may concern:
Be it known that I, JOSHUA B. GODWIN, of IVashington, in the county of .Beaufort and State of North Carolina, have invented a new and useful Improvement in Lamps, of which the tollowing is a specilication:
The object of this invention is to so construct a lamp that a constant flame may be maintained ot' diminished sizea flame, for instance, suitable for a sick room may be maintained after the ordinary wick is extiguished-and it consists of a taper wick-tube and wick in combination with an ordinary lamp-wick.
In the accompanying drawing, Figure l is a vertical section of a lamp constructed with a taper wick. Fig. 2is ahorizontal section, showing the perforated cone, the taper Wick-tube, and the shafts of the rag-wheels for feeding the wicks. Fig. 3 is a longitudinal section of the taper wick-tube.
Similar letters ot' reference indicate corresponding parts.
A is the taper wick-tube. B is the taper wick. This taper wick is made entirely separate from the common lamp-wick, but is arranged parallel with it.
In the Argand or tubular wick it is convenient to arrange it within the tubular wick-tube. When the at wick is used the taper wick is\` placed parallel with, and in near contact with, i the tlat wick-tu be.
The taper wick is preferably a round cord in the tube A, of sufficient size to emit a small taper llame, suitable for the sick-room. This taper wick is raised and lowered by means of the shaft D, rag-wheel E, and linger'wheel F.
I do not confine myself to any particular kind of lamp, or shaped wick, my sole object being to provide means for producing a small light in a lamp of ordinary size without being compelled to turn down the common wick flame, and thereby vitiate the atmosphere.
I am aware that camphene and other lamps have been provided with two or more separate wick-tubes; but
The taper tube A, placed in a lamp-burner parallel to, and in connection with, the ordinary wick-tube, as and 'for the purpose specitied.
JOSHUA B. GODWIN.
