Letters Patent No. 94,7 7 6, dated September 14, 1869.

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

To all 'whom tt may concern:

Be it known that we, WILLTAMl F. RIPPoN and GEORGE A. JOHNSON, of Providence, in the county of Providence, and State of Rhode Island, havein- -vented a new and improved Lamp-Wick Adjuster; and we do hereby declare that the following is a full,

clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

The object of this invention is to provide an adjustf Vable spring-presser, for use in lamp-wick tubes, for

regulating the breadth of the Wick-passage in the said tubes according to the wicks,'which vary materially in thickness.

The said invention comprises, in connection with a fiiction-roller opposite the ratchet-wheel, a spring, counect-ed to the burner, and projecting downward along the Wick-tube, of the same width as the interior thereof, between which and one wall of the tube the wick passes, and is closely confined between the spring and the said wall of the tube by the spring, which is set to have a natural pressure in the direction of the said wall; the said vpressure being governed by the frictionroller, in a manner to avoid friction by the said spring on the wick, and the said spring and tube are grooved or corrugated, asa further means of reducing the friction thereat.

Figure 1 represents a sectional elevation of a burner, and side elevation of a tube with our improvements applied;

Figure 2 represents a transverse sectional elevation of the same, taken at right angles to the plane of fig. 1, and on the line x x,- and Figure 3 representsa horizontal sectionof the same, taken on the line y y.

Similar letters of reference indicate corresponding parts.

A represents aspring, connected to the top of the burner at B, and projecting downward in the tube O,

bending around the friction-roller D, which is supported in bearings connected to the said springat the bend. This spring ibs so adjusted relatively to the roller, and to the side E of the tube, that when the roller presses the wick against the ratchets F, with the proper force to insure the working of the wick up and down, the lower end of the spring will press the wick against the side E of the tube, with justr'sui'i cient force to close the passage against the escape of gas from the lamp below, but without suiiicient friotion to obstruct the free working of the wick.

The spring, at the part where it bears against the wick, and also the part of the wick-tube opposite and in conjunction with which it acts, are corrugated vertically, to reduce the amount of the surfaces coming into contact with the wick, which we consider also re` duces the friction.

It will be seen that by this arrangement the requisite pressure of the wick against the ratchets by the friction-roller, to insurevthe working of the wick, will always be had, whether' the wick be thick or thin, and that the passage below for the wick will always be adjusted to the thickuess'of the wick.

The passage behind the spring, and between it and the other side of the wick-tube, is closed by the bent end of the spring, as shown at H.

Having thus described our invention,

We claim as new, and desire to secure by Letters Patent- The combination, in a wick-tube of a kerosene or other oil-lamp, of a spring, A, and friction-roller D,

acting iu conjunction with the ratchet and .the wicktube below, when the said spring and the part of the tube with which it acts are corrugated, and al1 constructed and arranged substantially as specified.
