WlCK-ADJUSTING DEVICE FOR LAMPS.

SPECIFICATION forming part of Letters Patent No. 566,882, dated September 1, 1896.

Application filed January '7, 1895. Serial No. 634,030. (No model.)

T0 (0% whom it may concern:

Be it known that I, JAMES M. USHER, of

.West Medford, county of Middlesex, State of Massachusetts, have invented an Improvement in \Vick-Adjusting Devices for Lamps, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a novel and simple wick-adjuster for oil-lamps.

My invention is particularly adapted for use in connection with a lamp of the type shown and described in Patent No. 545,313 to Ronald J. Robertson, and I have in the accompanying drawings and specification elected to describe my invention as applied to a lamp such as shown in the Robertson patent, although it should be understood that my invention is not necessarily limited in its use to such particular construction.

In the drawings, Figure 1 represents a lamp provided with a wick-adj uster embodying my invention, and Fig. 2 a perspective view of one form of wick-adjuster.

Referring to the drawings, the oil-reservoir A, the neck Ct, supporting the bulb c of the wick-tube c and provided at its top with the burner c, the wick f within the tube and terminating at the said burner, and the outer chimney or globe b are and may be all substantially of the construction shown in the said patent.

My improved adjuster m (shown separately in Fig. 2) is U -shaped in form, one of its arms, m, being adapted to enter the wick-tube from the bottom, and is forked or otherwise suitably adapt-ed at its upper end (indicated at M to engage the wick within the tube, the other arm or body portion, m of the adjuster constituting the operating-arm, which, in the construction herein shown, extends upwardly along the outside of the tube to a convenient point where it may be grasped to adjust the wick without the vfingers coming in contact with any part normally immersed in the oil. To guide the operating-arm or body portion, I have herein provided the same with two pair of guiding-ears m which embrace the wick-tube and guide the adjuster in its vertical movement, but it should be understood that my invention is not limited to the use of the particular form and arrangement of parts as herein shown, inasmuch as many changes may be made within the scope of my invention.

I claim-- 1. The combination with a wick-tube, of a sliding wick-adjuster having a body portion arranged to slide along the outside of the tube, said body portion being provided with one or more guiding-ears grasping said tube to retain and guide said adjuster in its sliding movements on said tube, and an engaging arm turned upwardly within the said tube from the lower end of said body portion, adapted at its end to engage and move the wick within the tube, substantially as described.

2. The combination with the reservoir A provided with a neck, and a suspended wicktube provided with a bulb resting upon said neck and thereby suspending said tube, of a U -shaped wick-adj uster arranged wholly within said neck and accessible only on removal of said bulb and wick-tube, said adjuster having its body portion extended along the outside of said tube, and an arm extended from said body portion within and from the bottom of the tube to engage the wick therein, substantially as described.

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

JAMES M. USHER.
