Specification forming part of Letters Patent No. 38,628, dated May 19, 1863.

To all whom it may concern:

Be it known that I, IR. FOGG, of Portland, in the county of Cumberland and State of Maine, have invented a new and Improved Lamp-Chimney Adjuster; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a side view of a common kerosene-oil-lamp cap having my improvement applied to it, showing the chimney held in an elevated position. Fig. 2 is a vertical section through Fig. 1, showing the chimney in a depressed position, or resting on the top of the cap.

Similar letters of reference indicate corresponding parts in both figures.

It is a fact well known to persons using oillamps with a chimney attached to them that it is impracticable to remove the chimney after it has become heated, and great annoyance is sometimes occasioned when it is discovered after lighting the lamp that the wick is not evenly trimmed, for in attempting to remove the chimney one is very liable either to break it or to burn his fingers, or both; besides, lamp-chimneys which require to be detached from the lamp-cap to light the lamp or to trim the wick are always liable to be broken.

The object of this invention is to so attach a chimney to a lamp-cap that the wick can be readily trimmed or the lamp lighted without removing the chimneyfrom the lamp and without the necessity of handling the chimney at all, or disengaging it from its attachment.

To this end my invention and improvement consist in attaching the deflector or cone to the lower part or body of the lamp-cap by means of a strip of spring metal of a suitable length, which passes down through the lampcap in an inclined position, and has an enlargement formed on its lower end to prevent it from being pulled out of its place, said spring being so arranged that as the cone is elevated it will be moved to one side of the cap and held in this position by virtue of the friction of the spring binding upon its guides, as will be hereinafter shown.

To enable others skilled inthe art to make and use my invention, I will proceed to de- Scribe its construction and operation.

The drawings represent my improvement applied to a common kerosene-oil-lamp cap, in which a is the circular body of the lamp-cap, b the perforated ornamental portion, 0 c the two divisional plates, d the'wick-tube, and c the cone or deflector. This cone 0 is seated on the shoulder b, when it is in place on the cap, as shown in Fig. 2, and the chimney g is secured to the cone 0 by means of the curved lips h h and the thumb-screw 2'. It will thus be seen that the cone c with its chimney is removable. This cone 6 is attached to the body of the lamp-cap by means of a strip of metal, k, which is bent as shown in Fig. 2, soldered to the outer edge of the cone at one end and passed down through the slots 8 s, which are made through the plates 0 c. The enlargement t on the lower end of the strip It forms a stop for preventing this strip from being drawn up through the slots 8 s, and these slots are so arranged with reference to the axis of the lamp-,

cap that the strip 7c inclines toward the center of the cap from the circumference of the cone c. This strip is made of spring-metal, of suflicient thickness to support the chimney of the lamp, and by curving this strip K as shown in Fig. 2 its surfaces will bind upon the edges of the slots 8 s, and also upon the upper edge of the cap I), when it is drawn up to the position shown in Fig. 1, and the friction thus produced ,together with the inclined position of this supporting-strip k, will keep the chimney in the position in which it is placed. Then it will be seen that as the cone (and chimney) is elevated it moves to one side I of the center of the lamp-cap and exposes the wick-tube for all ordinary purposes.

The thumb-screw c, which secures the chimney to the adjustable cone 6, serves as a means or lifting the cone, or by which the cone may be lifted.

From this description it will be seen that I effect the objects above mentioned in a very simple way, and by a comparatively simple attachment, which can be applied to the common lamp-caps now in use for a very small sum without in any way changing the form or deteriorating the appearance of these caps. It will also be seen that I am enabled to dispense with the pivoted or hinged connections which have hitherto been used.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The application to a lamp of a thin elastic strip of metal adapted to guide the cone or chimney to one side of the vertical axis of the lamp and to support the chimney in an elevated position, substantially as described.

2. Combining with the base of a removable deflector a thin strip of spring-metal, arranged in the relation to the vertical Wick-tube 01, substantially as described.
