OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 465,004, dated December 15, 18291. Application led August 29, 1891. Serial No. 404,128. (No model.)

To a/ZZ whom t may concern:

Be it known that I, PRESTON WILLIS STRONG, of Chelsea, in the county of Tashtenaw and State of Michigan, have invented certain new anduseful Improvements in Oil- Stoves; an d I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accom panying drawings, forming a part of this specifcation, and to the letters of reference marked thereon.

My invention relates to that general class of oil-stoves used for heating purposes in which the oil-reservoir and the burnerare located in the lower or stationary part of the stove while the lamp-chimney and heatingdrum are in the upper or hinged part. In addressing myself to the problem of improving the construction of stoves of this class I have sought to provide an improved construction to carry out the idea of having the hot air that ascends from the burner into the heatingdrum commingle in said drum with a large body of fresh air conducted to said drum through the base and body of the stove without Contact with the burner, the design being to resupply to the air carriedfrom the burner the elements that have been abstracted by the combustion, thereby. preventing that disa-` greeable odor that is perceived from mosioil- Stoves, and at the saine time by increasing the body of air supplied to the heating-drum, and consequently the body of air discharged therefrom, greatly augmenting the heating capacity of the sto ve. The fresh air supplied tothe heating-drum is taken in at the base of the stove, passes up both the inner and outer sides of the annular oil-reservoir, (keeping the lat-ter cool,) and, being kept separated from the air supplied to the burner by close joints formed between the burner and its chimney, passes up into what I term a freshair chamber, forming part of the upper or hinged portion of the stove and passes thence into the heating-drum above. The fresh-air chamber may extend from bottom to top of the lamp-chimney and entirely surround the same, so as to afford an uninterrupted space for the upward passage of fresh alr tothe heating-drum; but for the purpose of eXhlbiting or cutting oif at pleasure the light of the burner I preferably divide said chamber, eX- cept at its upper end, into four parts, one at each corner of the stove, leaving the space between said four parts to be filled by eX- posed portions of the chimney. state that the chimney is composed of alternate metal and mica sections, and is so mounted upon the plate that makes connection with the burner that it can by a suitable projecting handle be conveniently turned to expose either the opaque or translucent portions at the said four spaces or openings, as desired, thereby enabling the light from the burn er-iiame to be turned od or on at will without. in any way disturbing the functions of the stove as a heater. I preferably make the outershell of the fresh-air chamberof cast metal, and by reason of the fact that the volurne of fresh air fiowing through said chamber to the heating-drum keeps down the temperature of said outer shell I am enabled to elaborately ornament and nickel-plate the said shell, and there is no liability of the plating thereon becoming discolorcd by excessive heat. To the plate upon which the fresh-air chamber sits I applyan ornamental hand-rail, which not only adds to the appearance of the stove, but serves as a convenient means of tilting the upper portion of the stove when for any purpose this is desired to be done.

There are other ldetails of construction which will be ll 1er einat'ter describe-d, and pointed out specifically in the claims at the close of this specilication. w

In the accompanying drawings, Figure l represents a perspective view of a stove embodying my improvements; Fig. 2, a longitudinal vertical section of the same; Fig. 3, a cross-sectional viewtakenv on the line a: x, Fig. 2; Fig. 4,51. bottom plan View of the plate which supports the burner-chimney. Fig. 5 is aperspective View of the chi nney; Fig. G, a detail view of the wick-raising appliance; Fig. 7, a plan view of the truck upon Which the stove is mounted.

Similar letters of reference in the several figures indicate the same parts.

The lower portion of the stove is shown to consist of a base A, having suitable legs, a

cylinder or casing B, and a flanged ring C at the top ofsaid cylinder, the said parts being I Would here IOO E-is the wicktube, which is connected by y suitable braces or spacing-strips to an outer cylinder F, that is in turn connected in a similar manner'to the inner side of the oil-reservoir. Oil is supplied to the wick-tube from the reservoir through a tube G. Within the wick-tube and connected to it by -braces orv strips, such as above described, is the water- `receptacle Il, hereinbefore alluded to, and between this water-receptacle and the wicktube is'slipped a short cylinder K, whose upper end is flared outwardly Afor a purpose to be presently described. Inside the wick-tube is the cylinder L, which carries the Wick, said cylinder being provided with a rack M, with which meshes a pinion N on an operatingshaft O, provided with a hand-wheel O, as shown. By turning the hand-wheel vthe wick can be raised or lowered, as desired.

Fitting snugly upon the outer cylinder F is a collar P, which, in'addition to the depending flange p, which engages the said cylinder,

is provided with an upwardly and inwardly curved flange p and with an outer laterallyprogecting trough-shaped flange p2, as shown in Fig. 2.

Upon the top of the water-receptaclel place a cover Q, which is perforated for the escape of the vapor and has a curved projecting flange q for delectng outward the llame of the burner.

When the burner is lighted, the heat generated thereby will cause the air to be drawn up on both sides of the wick-tube, that which comes up on the innerside being deflected by the flange kof the cylinder'K and by the flange q of the cover Q outwardly, and that which rises on the outside of 'the wick-tube being directed by the curved flange pof the collar Pinwardly, the result'beingto produce a flame of great intensity.

Resting upon the ring C, form-ing the top of the lower portion of 'the stove, Iis a plate R, vish'ch carries the lamp-chimney S and also what I term the fresh-air7 chamber T. This plate R is provided with openings r, leading -into the `four portions of the fresh-air chamber, a central opening r3, leading to the chimney, and with a depending Vflange r', which is adapted to rest in and closely tit the vtroughshaped flange p2 of the collar P of the burner, so as to prevent the escape of air laterally from the burner into the fresh-air supply coming up through the base 'of lthe stove around the oil-reservoir on Vits way to the fresh-air chamber. Upon the upper side of the'plate R there isformed `an upwardly-extending flange r2, over which lits varing s, which constitutes thebaseof thelainp-'chimney S.

The lamp-chimney proper consists, preferably, of sheet metal inthe form lof the frustum of a cone, having Afour openings in its lower portion covered with mica corresponding to the four spaces, one on each side of the stove, left between the four lower extensions of the fresh-air chamber shown in Fig. l. -A lug depending from the ring Shas connected to it a handle s2, by means of which the chimney can be rotated back and forth through a quarter of a revolution, so as to expose either -the metal or the mica portions, accordingly as it is desired to exclude or allowr the passage of the light from the burner.

By reference to Fig. l the general outward appearance of the fresh-air chamber T will be seen, and by reference to Figs. 2, 3, and 4 the details of its construction will be' disclosed. It will be noted that the upper vportion of the chamber entirely surrounds the.

upper portion of the chimney, Fig. gandthat the four lower extensions 'of the chamber t extend down to the plate R and `cver the openings r therein, Figs. V2 and 3,"while between the said lower extensions of thec'ha-inber project the portions of the chimney, as shown clearly in the crosssec'tional View, Fig. 2.

Of course it is not essential that the chamber have four extensions, -nor that the vchimney be exposed at four points, as rt'lle'nunrbe'r of these may be varied to'suit the taste ofthe constructer; but in practice I-have found'the construction shown satisfactory.

In the operation of my stove the -hot air from the burn-er, carrying suchmoistureas is evaporated from the water-receptacle,passes upthrough the central open-i-ng iin "the plate -R and into the chimney, and -is discharged in an intensely-heated state into thehea'tingdrum V, and there becoming commingled with the large quantityof vairdra-wn in from thefresh-airchamber'andbeing-freshenedand revived thereby, the whole isdi'schargedfin great volumes from theheatin'g-drumthrough the openings w in the topthereof Iinto the apartment. The flow o'f'fresh'airlup 'a'ro-und the oil-reservoir is sufficient to Akeep the I latter at all times cool, andthe com mingling of the air in the heating-drum 'so thorough and perfect as toobviate all-unpleasant odors.
