UNITED STATES PATENT OFFICEQ JOHN B. DEEDS, F TERRE HAUTE, INDIANA, ASSIGNOR OF ONE-HALF TO ANDREYV GRIMES, OF SAME PLACE.

LAMP-BURNER AND CHIMNEY-HOLDER.

SPECIFICATION forming part of Letters Patent No. 273,039, dated February 27, 1883.

Application filed December 30, 1882.

To all whom it may concern: Be it known thatl, JOHN B. Bases, of Terre Hante, in the county of Vigo, and State of Indiana, have invented certain new and useful Improvements in a Lamp-Burner and Chimhey-Holder; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable others skilledin the art to which it appertains to make IO and use the same, reference being had-to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

This invention relates to that class of bydrocarbon-burners in which the chimney is mounted upon a perforated metallic plate, through which the wick -tube passes, and above which is arranged a deflecting-cone.

The objects of this invention are to keep 2 the base of the chimney from being overheated and broken off by consequent expansion or sudden cooling; to provide a burner with a chimney-fastening device which will be antomatically adjusted to the chimney-base, as

5 the latter expands or contracts, thereby obviating breakage from undue cramping, and at the same time securing steadiness and a firm holding of the chimney; to secure a copious supply of air to the flame and a strong up- 3 ward current alongside the wick-tube, thereby obviating the production of smoke and the deposit of soot upon the burner-plates and chimney, and to prevent the extinguishment of the flame by sudden air-currents entering the burner whenthe lamp is being carried from place to place.

In the accomplishment of these objects the invention consists in certain novel constructions and combinations of devices, which will 4 be hereinafter particularly described with reference to the accompanying drawings, in which Figure 1 is a view showing the burner partly in vertical section in a plane indicated by the line w w of Fig. 2, the lower portion of the chimney in section, and the upper part of the oil-holder in elevation. Fig. 2 is a perspective view of the burner with the main deflecting-cone removed. Fig. 3 is a View of the (No model.)

burner, mainly in vertical section in a plane at vright angles to thesection shown in Fig. 1.

Fig. 4 is a perspective View of the deflectingcone and its exterior deflecting-rim. Fig. 5 is a perspective view of the air-guard.

Referring to Fig. l, the letter A designates the body or oil-holder ot' the lamp, and a is the internally-threaded collar into which the screw-nipple b,Figs. 2 and 3, of the burner is screwed.

B is the perforated chimney-plate, which is open at the central portion andjoined to the wall of the casing or chamber 0, which surrounds the lower portion of the wick-tube'l), the bottom of which is secured within said chamber, and the upper portion of which projects above the base-plate, and issurrounded by the supplementary deflecting-cone E, and separated therefrom byan air-passage, e. The wall of the chamber 0 is provided with perforations c c, to admit air, which passes up through said chamber and through the passage e, and is directed by the cone E toward the wick and flame.

F is the main deflecting cone, having the the flame-passage, and which is removably attached to the chimney-plate B,a-nd incloses the cone E, from which it is separated by an air-space, which is supplied with air through perforations p p in the chimney-plate outside of the cone E. Through these perforations and this air-space is supplied the main body of air which supplies the flame with oxygen in the usual manner, while the air passing through the supplementary cone E is designed to form a strong current or draft, which will carry the flame well up, and prevent any tendency to smoke or to deposit soot or cinder about the base of the flame and top of the wick-tube.

Upon the extreme surface of the main deflecting-cone F, and near its base, is mounted an outwardly and upwardlyinclined deflectingrim, the ofiice of which is to deflect cool air.

rising through perforations q q of the chimneyplate against the lower or base portion of the chimney H, and thus prevent the same from becoming unduly heated and liable to breakage thereby or by sudden cooling when the flame 2 araoeo is extingushed or cool-air currents strike the chimney.

The main deflector F is removably secured in position upon the chimney-plate by means of attached flexible metallic fingers ff, which are passed through apertures formed in the base-plate and clinched underneath said plate.

At the edge of the chimney-plate B is an upturned finger 'i, slightly inclined inward, to prevent lateral movement of the chimney, and an outwardly inclined finger, i, to the top of which a hinged curved spring-latch,j, having a finger-piece or handle, K, by which it may be operated. WVhen the chimney is properly located on the chimney-plate B, this latch is turned down upon the outwardly-projecting chimney-base, as shown in Fig. 1, and binds it to the chimney-plate with a yielding pressure, thus permitting the chimney-base to expand without danger of breaking, while the spring-latch will also expand or extend itself by its resistence if the base contracts, and thus hold the chimney at all times steadily and firmly. When it is desired to remove the chimney, the latch is thrown back, as shown in Fig. 2.

The letter L indicates an air-guard, consist ing of a circular metallic band, the upper edge of which is secured to the under surfaceof the chimney-plate B within the annular series of perforations q q and outside of the perfora-.

tions pp, the lower edge of this guard being extended down below the chamber 0, which said guard surrounds. Air must pass under theguard L to reach the perforations c of chamber 0 and the perforations p of the chimney-plate, and thus said guard serves to prevent sudden lateral air-currents fromentering the burner and blowing out the flame when the lamp is exposed to the open air or is being carried from place to place. No provision is made to prevent air from passing through the perforations q, as such does not reach the flame on its first entrance, but is deflected against the chimney by the rim G.

The Wick-tube is provided with the usual feed-wheels, operated by the end or handle m.

I wish it to be understood that whileI have shown the deflecting-rim G carried by the main deflecting-cone F, I do not limit myself to such arrangement, as said rim may be mounted directly on the chimney-plate and serve the same purpose that it does in the position shown in the drawings.

I am aware that it is not new to form an air-passage between the lamp-chimney and a metallic plate, and therefore do not claim such, broadly.

Having now fully described my invention and explained the operation thereof, I claim 1. In a lamp-burner, the combination of the chimney-plate, having perforations within its margins, upon which the chimney rests, with 3. The combination, with the main deflect-.

ingcone having affixed thereto the circumferential deflecting-rim Gr,the chimney-plate having perforator p, and the wick-tnbe,of the supplementary deflecting-cone E, and suitable means for directing a supply of air within said supplementary cone, substantially as described, and for the purpose set forth.

4. The combination of the supplementary cone E and the wick-tube of the chamber U, having pelforations in its wall, with the airguard L, substantially as described.

5. The main deflecting-cone F, carrying the deflecting circumferential rim G, substantially as described.

' 6. The main deflectingcone F, having the outer circumferentially-deflecting rim G and the flexible metallic fingersff, by which it may be removably secured to the chimney-- plate, substantially as described.

7. Thelamp-burnerconsistingofthechimneyplate having perforationsp and q, the chamber O, having perforations in its wall, the wick-tube having its lower portion in said chamber, the supplementary deflecting-cone E, surrounding the upper portion of the wick-tube, and the main deflecting-cone F, carrying the deflecting rim G, the whole constructed and arranged substan tially as described.

In testimonythat I claim the foregoingas my own I affix my signature in presence of two witnesses.

JOHN B. DEEDS.
