ATTACHMENT FOR LAMP-GI-IIIIlllIIH LYQ.

; Specification of Letters Patent. I

Application filed January 15, 1910. Serial No. 638,299. f

Be it known that I, CALHOUN D. Hnno'n'n, citizen of the United States,-.residin Draper, in the county of Pulaskiand tate of Virginia, have invented certain new and useful Improvements in Attachments for Lamp-Chimneys, of which the following is a Specification.

My invention relates to the burners and chimneys of oil lam s, and particularly to a device adapted to e,supported above the lamp'so as to direct the heated air ,and smoke toward t e center of the space inclosed Within the chimney, the object of the invention being to prevent smokin of the I reaking because of the heat of the flame, to prevent the lightbeing extinguished by down drafts,

and to permit the flame to. be turned up so that the lamp will give better light without danger of smoking.

The invention consists essentially in a conical hood supported within the lamp chimney and above the burner of the same, the small end of the hood being located upward, this hood acting to direct the heated air and the products of combustion toward the centerof the space inclosed by the chimney and away from the chimne itself, the hood also acting to minimize own drafts and thus lessen the chance of the flame being blown out.

A still further object of the invention, in one of its forms as contemplated by me, is to minimize the chance of the chimney being accidentally disengaged from the burner or chimney base- For a full understanding of the invention -and the merits thereof, and to acquire a knowledge of the details of constrdction, reference is to be had to .-the following description and accompanying-drawings, in which:

Figure 1 is a longitudinal section of a lamp chimney, the burner being shown in elevation, with my invention shown in lace therein; Fi 2 is a perspective view 0 the conical hoo detache from the burner; Fig.

i ,3 is a side elevation of a burner, the chimney thereon being shown in section, with another form of my inventlon applied thereto; and, Fig.4 is a fragmentary perspective showing the ping for supporting the hood upon the burn r base.

Patented J Referring to Figsll and 2, in which the simplest form of myinvention is shown, designates aburner of any usualcharacter,

and B the chimney-thereon, this'chimn'ey" being formed with'the usual enlarged portion I; and the upper contracted neck I). My invention consists in the use within' the chimneyof an inverted conical hood 2which is smaller than the chimney itself and is therefore. 'spaced therefr'om', 7.-the upper and lower ends of lthis' hood being open.. The hood is supportcd'above the' burner in any suitable manner. 'As shown in the. figures above referred to, the hood, which-maybe of metal or of any refractory substance, is provided with the supporting strips 3; which are attached to they hood in an suitable manner, the upper ends of the strips being bent outward, as at 4, to engage witlfthe lamp chimney below the neck 'b-. thereof while the lower ends of the strips extend outward in line with the conical face of the hood and at their lower ends are sli ht ly bent outward so as to engage the lam ney in the enlarged portion 1) thereo which a is below that supporting strips 4 are preferably resilient so that the hood 2 inay be placed within any part of the bulge where the lamp chimney commences to'contract. The' ordinary sized lamp chimney and will be held therein by the resilience of the strips 4. As shown, the strips 4 are riveted to the hood 2, but any desired means'of attaching I the strips may be used.

In Figs. 3 and i I show another form of my invention which, while it contains the essential features present in the form pr'e-' viously described, also provides means for preventin the detachment of the chimney from the urner. In these figures, A designates the burner and B the chimney. 7 designates the coriical inverted hood, preferably of refractory material, the upperend of this hood being formed with a contracted neck 8. The lower end of the hood is attached to resilient supporting strips 9 formin standards which are curved outwardjo t approximately the outward bulg'e or curve of the lamp chimney, the lower ends of the stri s being engaged with or mounted upon t e I base of the burner A. Preferably, in order to detachably support the strips 9',upon the burner A, I provide the lowerends of the strips 9 with the ring 10 which is of suflicient size to fitupon the base of the burner r Ereferably made of material having a re ecting inner surface, as such a surface acts to give an increased light.

The advantages of my invention are as follows: The inverted cone su ported above the flame and in spaced re ation to the chimney, prevents the smoking or smutting of the chimney. This is effected by reason of the hood being of sufficient size to entirely cover theflame. The heated products of combustion, however, rising from the flame, are directedby the hood inward so as to form a heated column of air rising through the center of the chimney and not coming in contact with the chimney'itself. By reason of this fact .that the heated products of combustion are ke t away from the chimney, the light may, e turned higher than with the ordinarychimney, andthus a larger flame may be used, resulting in a better light.

My attachment also decreases very materially the breakage of chimneys, due to-the heat of the flame, by reason of the heat being directed toward the center of the chimney and being kept away from the walls of the chimney, thus the chimney remains cool at all times. Further, the cone prevents the extinguishing of the light by reason of strong gusts of air forced down the chimney, as when the lamp is being carried out of doors, or in laces where there is a strong draft. It will 0 obvious that a down draft of air will be diverted toward the chimney, and onl a relatively small proportion will pass do n through the central opening and strike the flame.

'With the construction shown in Fig. 3, an additional advantage is gained, in that the attachment securesthe chimney t0 the burner in such a manner that the chimney cannot be displaced by any jar or blow. This is effected by :means of the standards 9 which, bulging outwardas they do, correspond to the outward curve of the chimney,

and by reason of the spring therein, secure the chimney firmly in place, at the same time permitting thechimney to be lifted in order 'to light the lamp.

\Vhile I have shown what I believe to be the essential features of my device, and the best form thereof, I do not wish to be limited to these detailsof construction, as it is obvious that the principles of the invention might be embodied in a number of differing forms.

It will be obvious also that the device is adapted for use on all kinds of kerosene lamps and lanterns using chimneys, and that the attachment may be so shaped as to be adapted for use in any shape of chimney.

While I have described the hoods 2 and 7 as being made of metal and as prefer- .ably having a reflecting inner surface, I

wish it understood that may use any suitable material for this purpose, this material being preferably refractory, and that I may parent refractory material.

Having thus. described the invention, what use for this purpose mica or other transfrom the lower portion of the hood and adapted to engage the inside face of a lamp chimney, said'strips acting to support the hoodand center the same. I

2. The combination with a lamp burner, of a conical hood 'open at both ends, and downwardly extending strips attached to the margin of the-hood and at their lower ends engaging with. the burner to support the hood thereon, the intermediate portion of the strips being outwardly bowed for frictional contact with the inner face of the chimney along their whole extent.

3. An attachment for lamps, comprising a ring adapted to fit upon the base of a lamp burnerfclznnps on said ring, for engaging said basc, upwardly extending supports on the ring and a conical hood mounted on the upper end of the supports.

4." An attachment for lamps, comprising a ring adapted to be attached to the. base of a lamp burner, outwardly extending tongues on the ring adaptedto be bent beneath the base of the burner, supports on the upper ends of the supports, the hood being open at both ends.

5. An attachment for lamps, comprising a ring adapted to fit over the base of a burner-and having clamps for engaging said base, upwardly extending supports on the the ring, and a conical hood mounted on on the upper end of said hood, said supports being resilient and outwardly curved to fit against the inner face of the chimney;

6. An attachment'for lamp burners comprising outwardly bowed, resilient members adapted to have frictional engagement with the inside face of a lamp chimney, said members at their lower ends being formed with clamping tongues returned on them- 10 selves to engage. with the edge of the base In testimony whereof I affix my signature in presence of two witnesses.
