IM PROVEM ENT I'N LAM PS.

-' Specification forming part of Letters Patent No. 21,576, dated September 2l, 1858; Reissue N0. 3,082, dated August 11, 1868.

To all whom it may concern.' Y

Be it known that CHRISTIAN REICHMANN, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, hasinvented certain new and useful Improvements in Lamps for burningkerosene, benzine, andother hydrocarbon fluids 5 and the following is hereby declared to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure l represents a perspective view of the upper part of a lamp provided with a burner constructed in accordancewith this invention. Fig. 2 represents a vertical central section of the same, and Fig. 3 represents the method of molmtin g the cone or detlector upon the wick-tube.

The improvements which are comprised in the present invention relate to burners for hydrocarbon iiuids, the object of the said improvements being to produce a burner which shall be safer for every-dayuse and more easily and readily manipulated, and at the same time give more `light, than ordinary burners 'employed forlike purposes.

To enable others skilled in the art to understand and use this invention, the manner in which the same is or may be carried into effect will now be described by reference to the accompanying drawings, in which similar letters of reference, where they occur in the separate figures, denote like parts of the burner.

A represents the lamp, to the top of which is applied a burner, whose base a is of any ordinary 'or suitable construction. The base supports the iiat wick-tube b, which extends upward some distance above the base, and carries the ordinary wick-adjusting pinions and shaft c.

Upon the upper end of the tube there is a frictionsleeve, d, from whose opposite sides extend two arms or supports, e, upon which the dome or deiiector fis supported, being soldered or otherwise suitably secured thereto. The dellector may be of any ordinary or suitable form, slotted to admit the passage of the flame, andopen at the base or bottom. It is raised a considerable.v distance above the base of the burner, as will be clearly seen by nently joined to the tube, will be held, as before, in an elevated position above the base.

In a biuner thus constructed three thing are especially noticeable: A

First, the deilector and wick-tube are sol combined that while directly connected-1l. e., by means of the arms or frame e-light passes out, or is reflect-ed downward from between them.

Second, that part of the burner most liable to become highly heated is islolated or removed from contact with the base of the burner. The base of the burner, therefore, 'which forms thecap or cover yfor the luid-reservoir in the lamp, is at all times quite cool, 'and can be readily handled without-trouble 5 moreover, the iiuid which exudes from the wick, and gathers in and around the base, is prevented from becoming heated and vaporiZed-a frequent source of explosions of lamps of this kind being thus removed. IIhe burner shown in the drawings may beconsidered as composed of two distinct sections or groups of elements connected through the medium of the wick-tube. When the-lamp is lighted, the deflector and other parts yadjoining the ame necessarily become much heated, but the only medium for the communication of this heat to the base is the wick-tube, the heat of which is dissipated and carried off by the surrounding-air before it can reach the base.

Third, the deiiector and other parts surrounding or covering the wick-tube are made adjustable with relation to the said tube, and can without diiiiculty be applied to or removed from the same.

Under the two preceding features of the invention, it is not necessary that the upper portion or section of the burner should be made adjustable with respect to the wick-tube, but by mounting the deile'ctor or the deilector Same.

and chimney-rest upon afriction-sleeve fitting the tube the parts can be manipulated with great ease, and there is no need of detaching the chimney and deiector separately in order totrim the wick, which at any time can be eX- posed to view by slipping` oil' the sleeve from the tube. rlhe defleotor in this manner can be adjusted upon or removed from the wicktube, as desired, While the wick may be readily lighted through the open base of the dome.

It is needless to say that the deector can, if desired, be used with the ordinary chimney rest or holder, the latter being in this case attached to the arms. The sleeve acts, also, as a guide to direct the deflector, so that its ob- .long slot or opening shalllie in the same vertical plane as the ilat wick-tube.

A further feature of this invention consists in forming around the base of the dome aseries of peripheral springs, which serve to support and steady the lamp-chimney. These springs g are represented plainly in the dit ferent figures of the drawing. As, shown in Fig. 2, they are formedin-one piece, with the dome extending out from the base ofthe The arms of which the springs are composed are struck out from the metal which forms the dome, and are turned or bent up so as to form springs for holding and steady ing the chimney in its proper position.

That portion g of the arms Whichis not bent upward is used as the seat on which the base of the chimney can rest. The intervals h between the springs or arms form air-spaces, through which, when the chimney is in posi-V tion, the necessary supply of external airpasses up within the chimney, as indicated by the arrows, Fig. 3.

Having now described this invention, and

the manner in which the same is or may be` carried into ei'ect, we do not wish to be un derstood as limiting ourselves `to the precise' construction and arrangement of the parts of the burner as herein described, forr it is apparent that the same may be varied inl many respects Without departing from the principle of the invention; but

What is claimed as the invention of the said REIormANN is as follows: Y 1.- The combination of a fiat wick-tube withV a dome or deilectorfhaving a corresponding oblong' opening or slotQunder the arrangement, substantially as shown .and described, so that,

while directly connected with each other, the said parts shall allow light to pass out or be reilected from between them, as set forth.

2. The combination of a iiat wick-tube with a slotted dome or deilector, and arms or frame, whereby the said dome is held on the wicktube in an elevated position in relation thereto, substantially as and, i'orthepurposes shown and described.

3. The combination of the deilector, and its supporting arms or frame, and sleeve, with the wick-tube,substantially as and for the purposes set forth. Y A y 4. A lamp-burner composed of two groups of elementsthe 'rst consisting of the base with its wick-tube and wick-adjusting rack and pinions the second, oi a chimney-holder, delector, and such otherparts-as maybeneeded for the 4proper combustion of the fluid, so as to produce an illuminating-dame; the two groups being united by friction, and the latter, when inpositionin the burner, being supported by the former without the intervention of any mechanical'device, whereby the two may be -rigidly connected together, substantially as and for the purposes herein shown and set forth.

5. The coinbinatiomwitha ilat wick-tube, of

'a correspondingly slotted but elevated dome, i

provided with peripheral springs for holding the chimney in proper position, as set forth.

6. The combination, with the base and dat wick-tube, of a chimney rest or holder, an ele-- vated dome provided with peripheral springs, and a sleeve and frame or arms for holding said dome in position with respect to the wick- -tube, substantially as and for the purposes herein shown and described. 7. `The combination, with the dome or deector, of a series of arms projecting from the periphery of said deilector, and arranged, as herein described, so as to constitute both the seat or rest for the lamp-chimney and the springs by which the said chimney is steadied and held in position,substantially as setforth. In testimony whereof we have signed our namesto this specication before two subscribing witnesses.
