1e azi when.; a may hamm i SouthBen'Lin the county of St. Joseph and' State of Indiana, have invented certain new 'and useful Improvements in Oil-Stoves; and

I .do hereby declare the following to be a full, clear, and exact description of the invention,

such as willenable others skilled inthe artI to which it p'ertainsto make and use the same.

.'.lhis'invention relates .to new. and usefull improvements in oil-stoves; and the inveng tion consists in the peculiar construction and arrangement o fjthe various parts whereby a.

more convenient and 'ecient stove* is p roduced,t all asmore fully hereinafter described. v rIn the accompanying drawings, Figure 1 is fa vertical central longitudinal section of my.

Fig. 9 is a planjview of oneof the perforatedy ff partitions, and Fig.f10 is anenlarged section 'through th`oil-supply nozzle, v

L

j is a sleeve', which on its outer edge 4is prol'videdwith a rack-bark, with which the pini 7 o ion Z of thewick-raising shaft m engages, a

suitable .olset beingfornedinthe outer sidefof the' wick-tubeE rack-bar..

To placca wick-inthe wick-tube it is rst of the wick Hush withthe bottomof the sleeve,

and then the inclined 'annular clam pingfrn'g for the passageot this o is inserted 'mtheflottom of the sleeve, clamping the wick o'rmly between it. and the'- sleeve, as plainly shown in Fig.- 3.. The parts are heldin this position by means fof the i springp, which engages under the lowered'ge of the`w'ick the clamping-ring. yThe sleeve.

thus fittedlwith the wick is now inserted-into by'means of the rack-bar andlgear-wheel in vthe ordinary mannerl' i It will be observed that I have lplaced Vthe oil-supply aperture I immediately infront of the hinge K,Y so that when the top'is tipped upon its hinge it willfinterposenthe fire between the operator Vand the oil-supply aperture I, which would prevent his filling the Atankwithofutjputting out the re,"theap proach to the, oil-supply aperture from the other side being prevented by the upturned end of the top. Y l

annular rim q, Aforming between it and the `sc rew.`t hleaded nozzle of theapertnre the an- Around the oil-supply aperture I forni lan nular weell fr. The screw threaded noz'zle I provide at its base with apertures s, which the capi whenv screwed to its lowest position I7s"- insertedwithinthe sleeve Awith the bottom 5.5 the wick-tube andlowered to the desired point will close, but which whenlthe cap is' partially screwed down will allow the oil in the well fr to enter the apertures, and thus pass into the tank. Within the nozzle-I form the' lips iR the opening Vintqa downwardly-projecting flange 1" wherebyt-he operator in filling lnay see the level of the oil before it reaches the top. The top B consists of the main ,casting L, which at K is hinged to its base. To this base is' secured a suitable fender M. The casting L is provided with a series of apertures N, which communicate when the top is Vdown with the air-chamber d, and is also pro- ,vided with an annular opening O, which forms the `aperture through -whichthe flames pass `from the top ofthe wick tube. A, Upon the main 'castingL are supported thewalls P and Q, the former forming the outer cylinder-casing `and secured at its bottoni to the lower casting L, and tits npperend-supportinga snitable ornamental 'perforated top R'.' The wall Q is similarly secured upon thepcastingL' at its lower edge, and at its upper edge it .connects to aftop platetS.- lThis top plate is centrally apertured, and within this apertureisk Secured the depending central tube Q. Be#

. tween the walls P and Q is formed an annular-a'ir-chamber P', and between the walls' Q and Q' is foruiedl an annular combustion chamber R'. Within the tube Q is formed Vthe chamber R2, which connects at the lower vend into the contracted'deflecting plate R3, secured at its lower end upon-the air-tube F. The top plate S isin the shape of an annular casting fitting over' the chamber R and pro-- vided with a series of. apertures S', which are adapted to be opened and closed by means of a sliding damper Sffcorrespondingly aperftnred, whereby.the products of combustion may be allowed to pass outthrough this damper into the chamber below-the top, and from -thence through Athe perforationsinto the Vroomgor by closing the damper it may be made to pass out through the stove-pipe '-l. The damper T of thev stove is pivoted upon the shaft U, which has a crank- U' engaging with the handle Ssot' the damper S2, all so arranged that upon opening the damper S2 t0 alloyv the products 0L combustion into theroom thedamper 'I"r is closed, and upon c1osing the damper S2 the damper T' is opened.

The top R, I construct in two parts u u', the part u being supported upon the casingP Iand provided withvthe inwardly projecting arms u, and with the annular ilangc v. The top of cover u yrests upon the arms fuand bears against! the auge v, forming a .tight joint and giving the appearance of a single completed top. l

, By providing outerair passage in'close proximity to the combustion chamber, and com-l municating with the chamber d above theoil fount, the air in the passage is heated,.and creates an increased draftaronnd theoil tank and up.through the air passage. It makes very little'diterence how open the castings may be around the fount, Vfor if. there islnot v an air pass above to createaldrafttfhp radiant heat from the castngabovefthe fount` will heat the' odor; v n

VThe parts being thus ranged, they are intended to operate as fol.

fount suiciently to cause an constructed land arf lows: The tank being filled withgoil'and the M `Awick suitably raised, the top -being turned in position, as shown in Fig, jl, after the fire is lighted the 'Haines willfimpinge upon the inclined sides of the'contracted ring R3, thereby f rapidly heating the air'within the chamber R2 and creating a quick circulation through it and its complementary tube F. It will be seen that the air-supply for the flame is given through the passages (t and b. Vrlhe airin the chambe'rP being heated by the hot air in the combustion-chamber rapidly rises and enters the top and then passes out into thefroom, a

nnlar passages c and e, the `continual passaggiey new supply of air beingvfurnished'though theiaperture N from the chamber d, which is p supplied beneath the stove through the anof air around the oil-tank' keeping it'cool. Y

When'the oil is exhausted in the oil-tank, the

iary supply 'of oil'in the projections around the wick-tube it will not burnpthe wick for a.`

long while after giving warning of. the condition of the oil`tank,as'would bex/the case if L these were absent.` This has been a-consta'ntsource of trouble in/ oil-stoves, that without giving any warning when the oil was nearly exhausted ther fire wonld'gov dow-n and char theV wick, thereby rapidly destroying it. By

this auxiliary oil-supply. I form an ecient means ofpreverrt'mg thistrouble with any ordinary carein running the stove. It will be seen also that my combustion chamber forms a middle passage-way, the walls thereof having contact on the inside with the inner airchamber and on the outsidewith the'outer air-chamber. This construction Agives' me the' most eflicient results from the heat in the products of combustion being given out rapidly into the air chamber upon both sides.

In order to retard somewhat theforward dow of the draft in the combustion-chamber and thereby get better results'fro'm'the heat from'the products of combustion, I arrange lone o r more annular;perforated"partitions Ui4l within 'the combustion-chamber, which Ihold therein by suitable grooves or projections in the walls of the tube Q upon one side and the wall Q upon the other` side, as shown at U, which forms a sutablesupport and below the perforatetpartitions. I also cut out the edges of this'partition and bend them slightly upor down to getA the spring action of the metal andhold it in place, as plainly shown in Fig. 9.

r ro" The end of the stove-'pipe T, I support by means of the bracket W, whichis securedat its lower end to the foot-rail M, and at its upper end is 'provided withpa sui/table collar to embrace thev stove-pipe, all so arranged that when the stove is turned down the stove-pipe as described.I
