,447, dated a... s, 1862.
, Be it known thatl, WILLIAM HOWARD, of Flushing, in the county of Queens and State for Coal-Oil Lamps; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had making a part of this specification, in which- Figure 1 is a vertical central section of my invent1on,taken in the hue mm,
Fig. 2; Fig. 2, of the same, taken in the.
Similar letters of reference indicate correspondingyparts in the twofignres.
e and use my invention, I will. proceed to de scribe its construction and operation. k I A represents a glass chimney,and B aglass cone or deflecton, These parts mayboth be detached and appliedse'parately to. the lampt'he chimney and attach the lower edges of the The cone and chimneymaybe blown or gether in one piece atone operation; and in the lowerv part of the chimney'there'are made together are applied to. the burner,they have The base of the cone or flange a is fittedin the and'may be secured therein The advanta lows:
First. The 00 ges of the invention areas fol ne" being permanently atfrom and applied to the burner. simultaneously, and hence notonly time is saved incasual dropping rendered less frequent, as
one piece is handled instead of two, and the glass'cone being small, is;wh'en detached from the chimney as heretofore, dropped, especially by careless persons; besides the parts are stronger combined than whenscparate from each other.
, Second. The combined. chimney and cone very frequently may be manufactured at a less cost than when made separately, as heretofore.
Third. By having the holes I) made in the chimney, as shown, the air is admitted to the exterior of the flame at a point'nearer its base than formerly and acts upon or impinges against it in amore direct manner and will insure perfect combustion with a low or small flame-a result which is not attained in an ordinary burner, in consequence of said draftholes being "at or in q the base of, the cone.* Fourth. Theadvantageof the ordinarydeuite close proximity to j tached glasscone is obtained, to witathe-radiation of the light afforded by thelower part of the flame within the cone; without the disadvantage of the latterv fracturing by expansion in being heated'a result due to the fast- 7 .ening mechanically of the chimney to the base of the cone and directlyover the draftpassages which supply the exterior of the flame with oxygenand which are form-ed. by radial grooves or corrugations at the base of the cone. The air passing through those passages at the bottom of thechimney keeps the lower part of the latter comparatively cool,
while the cone, on account of its close proximity to-the flame, rapidly heats and expands, and. the chimney 'being'insulated from the cone by the air-passages does not readily expand, and the break. w
By my inventiou'it will be seen that the chimney and cone, in consequence'of being formed in onepiece admit of the heat being conveyed to the lower part of the chimney from the cone, and the former is allowed'to expandwith the latter prevented.
I am aware that detached glass cones have been used, and these I do not claim. I am also aware that the lower part of the chimney has been so contracted as to dispense with the use ofa cone, as shownin Dickies -and fracture thereby patent, 1862. This, therefore, I do not claim.
cone consequently isliable to 2 n sum as new and desire to secure by Lebbers Patenbdescribed As an improved article of manufacture, a

Having thus described niy inventionl claim the cone and chimney, all asherein shown and WILLIAM HOWARD.
