IMPROVEMENT IN LAMPS.

Specification forming part of Letters lfatent No. 36,692, dated October 14, 1862.

To @ZZ whom it may concern:

Be it known that we, SAMUEL ADLAM, J r., and J nRnMIAn R. FoGG, both of Portland, in the county of Cumberland and State of Maine, have invented a new and useful Improvement in Lamp-Burners Provided with Draft-Chimneys; and we do hereby declare that the following is a full, clear-,and exact description of the same, reference being had to the accompanying drawings, making a part of this speci` iication, in which-- Figure 1 is a vertical central section of our invention, taken in the line .r w, Fig. 2. Fig. 2 is a plan or top view of the Same.

`Similar' letters of reference indicate corresponding parts in the two figures.

This invention relates to an improvement in the manner of attaching the cone or deflector to the burner, as hereinafter fully shown and described, whereby the cone and draft-chim-V ney may be very readily turned aside or olf from the burner, so as to expose the wick-tube, and thereby render the wick accessible for trimming and lighting.

To enable those skilled in the art to fully understand and-construct our invention, we will proceed todescribe it.

A represents a burner,`which may be constructed in any of the known forms employed for burning coal-oil and other similar hydrocarhons with a draft-chimney. j

Bis the wick-tube, of the ordinary fiat kind, which is provided with serrated wheels C for raising and lowering the wick.

D is a dat rim or band,-.which is perforated withu holes a, extending all around it, as shown in Fig. 1. This rim or band is of such a diameter that it may fit snugly on the top of the burner and admit of the. perforations a being a triiie above its upper edge, as shown in Fig. l. The rim or band has a projection,

b, extending out from it horizontally, and to this projection a projection, b', .on the iiange or base c of the cone or deflectorE is attached by apivot, d. rIhe cone or deiiector is allowed to turn or work freely on this pivot, so that it may be adj usted on the burner A, or be shoved '0H' from it at any one side, as indicated in red outline in Fig. 2.

The cone or detiector E is of the usual form, and when adjusted on the burner for use'has its slot e in line with the top of the wick-tube B, as will be seen by referring to both figures.

The top of the wick-tube B is a trifle below the plane or level of the upper edge of the burner and the base c of the cone oi deflector, so that the latter may be shoved on and off the burner without interfering or coming in contact with theY wick-tube, (see Fig. 1,) and the base c of the burner is perforated with holes e', which extend all around the cone, as shown in Fig. 2.

F is a spring, constructed of a flat piece ot metal extending down through the burner and attached by solder or otherwise to the lower part of the wick-tube, as shown at g in Fig. 1. rlhe upper part of this spring passes through the side of the burner, and is bent upward in about a vertical position, and catches into a notch or recess, h, in the edge of the base c of the cone when the latter is adjusted on the burner, and retains it in proper position, the spring being held in the notch or recess by its own elasticity.

Gr is the glass draft-chimney, which is se-a cured to the base c of the cone or deliector by means of a screw, i, and catches j j, as shown in Fig. 2. The iialne is supplied at its base by air which passes through the perforations k of the burner and through the perforations c of the rim or band D, while the sides of the flame are supplied with air which passes up through the perforations or holes e in the base c in the base of the cone. (See arrows in Fig.` 1.)

ln order to shove the cone E and chimney G off from the burner for the purpose of lightA ing or trimming the wick, the spring F is pressed out from the notch or recess hin the edge of the base c, in order to admit of the cone being turned on its pivot d, the spring adjusting itself in its notch when the cone Vis shoved back on the burner in projperposition. By this arrangement it will be seen that the chimney does not require to be detached from the cone at any time for the purpose of trimming and lighting the wick.

Having thus described our invention, what we claim as new, and desire to secure by Let-` ters Patent, is-- j 1. So combining a chimney and lamp that the chimney may be removed from over the Wick of the lamp by a horizontallateral movea glass chimney, to be moved horizontally and ment of the chimney, and Without detaehing laterally relatively to the lamp-cap, and so as the chimney from the lamp, for vthe purpose to be latched toor unlatched from the cap, set forth. l substantially as shown.

2. Providing a chimney-holder and lamp- SAML. ADLAM, JR. Cap with latohing` devices or their equivalents, JEREMIAH R.
