`IMPRQVEMENT IN BURNERS FOR LIGHT-HOUSE LAMPS.

Specification forming part of Letters Fatent No. 177,825, dated May 23, 1876; application filed A l y March 22, 1876.

Be it known that I, JOSEPH FUNCK, of

` rEompkinsville, Staten Island, in the county of Richmond and State of-New York, `have invented a new and useful Improvement in Ar-V gandBurnersfor Light-HouseLamps, of which l the following is afspeciication:

AThis improved Argand burner is designed j primarily for Funcks hydraulic loat-lampfor light-houses, but is not conned in its applicability to this particular lamp.

The present invention has for its objects a thin even flame of superior steadiness and intensity, and a simple 'and eflicient burner, which is adapted to be readily taken apart, so

' as' to be kept perfectlyclean.

The first part of the invention relates to the l wick-tube or oil-feeding devices;` and consists in peculiar means for contracting the upper end ofthe wick, so as to lessen the charring thereof, and to improve its capillary action,

and also to render the flame thinner and more even at the wick. Y

TheV second part of the invention relates to the arrangement of air-supply orifrces; Aand consists in a perforated chimney-deluge, Iby which air is admitted immediately withinA the chimney at its base, so as to furnish fresh fair for the outside of the flame above the deector-dome, and to reduce the degree of heat to which the chimney -is subjected.

The third part of the invention relates to fo'r'admitting air tothe interior of the flame,

1as `hereinafter morefully set forth.

Figure l is an elevation of this improved burner. Fig. 2 is a vertical longitudinal section on the line 2 2, Fig. l. Fig, 3 is a horizontal section through the upper air-inlets on the line 3 3, Fig. 1. Fig. et isl a horizontal section through lthe lower air-inlets on the line 4 4., Fig. l.

Like' letters of ^reference indicate corresponding parts in the several figures.

`for the wick itself, but also forthe carryingring e3 of the Wick-elevator, with some additionalI margin to facilitate introducing the wick. r)This renders the upper end of the wick quite loose in an ordinary tube, permitting it to swell and fray, and, consequently, to burn freely itself, whereas the object is to confine Athe combustion as exclusively as possible to the exuded oil. To remedy this defect the Vouter wall of the wick-tube is made shorter than the inner wall, and the space thus exposed at the upper end of the tube is occupied by a contracting-collar, c1, as clearly shown in Fig. 2. The construction of the tube proper,l besides its primary el'ect, 'serves to afford additional facility for readily reuewing the Wick. The wick-contractor having been removed, the attaching-jaws of the elevated carrying-ring e3 spring apart above the low top of theouter Wall of the wick-tube, and release the old wick. The new Wick is placed. around the projecting upper end of the inner Wall ofthe tube, and within the jaws of the carrying-ring, and the wick is then Vdrawn in by lowering the ring. The contracting-collar is formed at theupper end of a sleeve, S1, which slides tightly onto the wicktube. The jacket J is attached to this sleeve, and is removable therewith.

The main air-inlets al a2 of the improved burner consist of a sufficient number of moderately large perforations, in circumferential rows, formed in the otherwise imperforate outer Walls of theV jacket J and cap C, as shown in all the figures.

The inlets a2 admit air` to vthe interior of t-he flame through the center of the wick-tube. Air admitted at the inlets al strikes the outside of the llame immediately above the wick,

T represents the annular wick-tube; E e1 lbeneath the dome d of the deflector, and a small portion of that which reachesthispoint "escapes unconsumed through oriticesin .the

' creases the brilliancy ofthe ame.

The deector D, in addition to its ordinaryA perforated dome and .the chimney-ange f, which is vformed thereon,has, below the latter, an apron or drop-partition, '11, extending down. below the air-inlets al, to divide andequalize the entering air, and. tocause the main portion to pass in lcontact with the sleeve s1 'throughout its length, so asto absorb heat from Vthe wick-tube. The jacket J is formed With a shoulder, 32,to form a seat for the flange f, and the deiector is thus supported within the jacket, solas to be readily'remov-l able, to facilitate cleaning it, and to Vgive convenient access to the interior of the jacketfo the'same purpose. The walls of the cap C are double, ac'on-j: "centric innerwall, t', of perforatedI sheet metal,y

Yhaving minute orifices, being--employed'to di` videup andregulate the force of the entering` l tube, adapted to receivethe'wickat'top, and

air. The cap is removable from the wick-tube, being attached by ascrew-collar,02,"en1bracing a threaded neck at 'the lower Aend otjthe tube. To render the'cap separable,"the screw- Vcollar c2`is'extended, and provid'ed'externally 'with a collar andthreaded portion Within the cap. The lat-ter `receives another screw-collar, o3, soldered Within thefupper endof theinner annular wall i. The outer Wallis soldered to` vthemain collar c2. The bottomfdiskb of the vcap is imperforate, land is "attached to .the-inner wall t', and nished with `a V"milled edge.. -By turning this the outer collar c3 is Iunscrewed, and the bottom disk and inner wall' Vare released. When they are in'position the bottom disk fits tightly against the loweredge of Vthe outer wall. The ordinary extension-g tube 64 to vaccommodate -the rack 'e2of the wick-elevator, is inclosed within the cap-G, asl in other burners.

The burner is supported'withinitsreilectory by the arm A,and is supplied withoilthrough a pipe, O. An ordinary'chimney 'upon the; chimney-ange f completesthe-'outtih When anew wick is to be introduced'thel jacket J and its contents can be removed together, while for trimming the wick the -deiector D alone need be removed 4besides the. chimney. i

The style ofthe air-inlets al a2 renderstheml free from liability to become clogged, and fa cilitates cleaning and polishing the outer surfaces of the burner, and the construction 'of vthe jacketJ and cap C, as-'above described, gives easy access to the inclosed parts which require cleaning.

do not claim, broadly, any device for holding the wick ot' an Argand burner around the upper "end of a relatively extended inner wall or central draft-tube. I am aware of vsuch a-burner having a wick-assembling shell,7 in combination with two`or more 4short wick-tubes, conducting separate wicks, which are assembled around the inner wall or drafttube by said shell. 'This shell is a fixture, fand the wicks are necessarily inserted at the bottom of the burner.l

:is employed, and the upper vpart of the outer Vwall-of the annular wick-tube is omitted. I do not claim any'suchdevice. Neither vdo'I claim, broadly, a removable detle'ctor, as I am 'aware that the simpledomeemployed in some Argand burners has been maderemovable. `The follow-ing is claimed as new and of this invention, namely:

l. In "combination with an "annular wickconstructedwithV a'xedl outer Wall,l termi natinga'short distance'belowthe upper extremity Vof the inner wall, thewick-contracter c1, vadapted to lbe Tapplied 'after the'wick is insei-ted, and to form a contracted extension of they outerwall of thewick-'tube independent y -of the wick-elevator,substantially as herein :shown and described.

2. The 'combination'of vthe'Wick-contraoter "al, formed'attheend'of the'sleeve s1, and the jacket J, Vvattached to ithe lower end of sai'd sleeve, fthe'same being Vadapted to be applied to and removedfrom' the wick-tube together, substantially as Vset forth.

3. The perforated chimnjey-flangef, in combinationwith the jacket J, dropportion p, and dom'ed,f0r'the purposes set forth.

4. The removabledefl'ect'or'D,consisting 'of 'the dome d,chimneyange f, and drop-partition p, in combination with'the jacket J, having theshoulder s2, 'to support thel same in'position, Ysubstantiallyv as 'shown' and described.

5. The removable and vseparable cap C, havying-concentric annular walls, a lbottom disk,

'151, and screw-collars 0203, combined substantially as herein described, for the purposes set forth. y
