ALFRED O. BRUNNE, OF MERIDEN, CONNECTICUT.
LAMP.
SPECIFICATION forming part of Letters Patent No. 404,162, dated May 28, 1889.
Application filed March l9 l 1888.
T0 aZZwhom it may concern.-
Be it known that I, ALFRED O. BRUNNE, of Meriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Lamps, of which the following is a specification.
This invention has reference to certain improvements in lamps with a central draft, said improvements being designed with a view to produce the more perfect combustion of the oil by supplying an additional quantity of oxygen to the outer as well as to the inner surface of the same, whereby a whiter flame is produced at a saving of the illuminant.
The invention consists of certain details of construction and combination of parts, which will be fully described hereinafter, and finally pointed out in the claim.
In the accompanying drawings, Figure 1 represents a side elevation of my improved lamp. Fig. 2 is a vertical transverse section of the upper or burner part of the same, drawn on a larger scale. Figs. 3 and 4. are respectively a detail side elevation of the lower part of the interior draft-cone and a horizontal section of the same on the line x a, Fig. 4t.
Similar letters of reference indicate corresponding parts.
Referring to the drawings,A represents the fou nt of my improved lamp, which is provided with a central-draft tube, A, and a base, A having openings afor admitting the air to the central-draft tube A. The central-draft tube A is rigidly secured to the bottom of the lamp-fount, as customary in centraldraft lamps of this class. A wick-holding tube, B, is arranged concentrically to the central-draft tube A and provided with the usual slots or openings, d, for permitting the access of the oil to the wick C, which is interposed between the fixed draft-tube A and the wick-holding tube B.
To the neck A of the fountA is applied, by
' a bayon et-joint, e, a perforated air-supply cylinder, E, as shown in Fig. 1. The perforated cylinder E is provided with an interior tube, E, that is concentric to the central-draft tube A, and forms with the same, respectively, the outer and inner wick holding and guiding tubes.
The perforated cylinder E is provided with Serial No. 267,595. (No model.)
a series of smallperforations, e, and with one or more rows of larger perforations, 6 which latter are arranged, preferably, at the upper or lower edge of the cylinder E, or at one or more intermediate points of the same. The smallerperforations, 6, supply a steady quantity of air, while the rows of larger perforations permit the entrance of extra sheets or bodies of air, which are supplied to the outer surface of the flame one to the base, the other to the upper part of the same. For the purpose of preventing, however the too abrupt supply of too large a quantity of air to the outer surface of the flame, the chimneysupporting gallery E at the upper part of the perforated cylinder E is provided with a perforated ring, 6 which is made either of a detaehable piece of perforated sheet metal, or
integral with the gallery E as desired.
In the drawings the perforated rlng e is made of a separate piece of sheet metal and fitted tightly around the outer wick-tube, E, as shown clearly in Fig. 2. 'lheperforated ring 6 serves as a screen for regulating and distributing the air in a uniform manner to the outer surface of the flame and prevents effectually the flickering of the flame, which would take place with a too large and unrestrained supply of air to the outer surface of the flame. The gallery E is provided with the usual spring-arms for supporting the lower contracted face of the chimney, the middle portion of which is bulged outwardly, so as to provide for the necessary expansion of the flame.
The fixed central draft tube A is provided at some distance below its upper edge with inwardly-proj eoting pins or studs f,which support the base-ring Fof an inverted draftcone, F. The draft-cone F is open at the top and bottom and attached by its contracted lower end to an interior seat, f, of the basering F. Segmental openings f are arranged between the inner seat, f, and the outer circumference of the base-ring F, so as to permit a separate current of air to pass between the draft-tube A and the interior draft-cone, F, in upward direction to the inner surface of the flame, as shown by arrows in Fig. 2. The upper end of the draft-cone F is made flaring in outward direction, so as to direct the flame in connection with a deflector, G, of inverted conical shapeavhich detlector is made of somewhat larger diameter than the upper edge of the draft-cone I! and extended above the same, so as to cause the impingement ol' the air-current which is drawn up at the interior of the draft-cone F on the upper part of the inner surface of the Ila-me. The interior aireurrent is heated. in its passage to the [lame to a higher temperature than the ant-current which drawn up in the annularchannel formed. between the draft-cone F and the lixed draft-tube A. As the highly-heated air-current impinges on the inner surface of the flame at a point above the point of impiug'ementol the less-heated air-current, that passes in upward direction to the flame in the annular channel. formed by the draltcone and dral'ttube, a more perfect combustion of the oil-vapors takes place, so that consequently, in connection with the steady supply of air to the outer surface of the (lame, a whiter tlame and a better light are obtained.
The detlector G is provided at its lower end with a perforated socket, g, which is supported on a shoulder, g, at the upper end of a spindle, G, which. passes centrally through the draft-mine l and is supported at its lower end in a central screw-eye, of a diametrical yoke, (l that sccuredto the base-ring 11". The yoke (l is preferably made of U shape and extended to some distance below the lower edge of the draft-cone l so as to obstruct as little as possible the free upward passage of the air to the interior of the cone F. The deflector ,l, the interior draft-cone, F, and the base-ring 11", with its yoke G can be readily removed from the supportirig-studs f of the fixed draft-tube A, so as to be readily cleaned and replaced.
The li'ountA is provided around the supporting 'neck A of the perforated cylinder E with a drip gutter or trough A, which is shown in Fig. 2, and which serves to collect the oil that passes to the outside of the neck bythe so-called sweatine"of the lamp. The
oil thus collected in the drip-gutter A is graduall y evaporated b y the heating up of the neck of the fonnt, and the oil-vapors are drawn up and mingled with the upward currentof air that passes through the perforated cylinder-cone, so that they are fed to the flame and burned by the same.
The essential features of my improved lamp consist in the uniform air-supply to the outer surface of the flame by means of the poi-[o .rated cylim'ler and the perforated distributing-ring ot' the gallery, and mainly of the interior detachable draft-cone and deflector, by means of which two separate air-ci'nrents of different tem ')eratures are conducted to the inner surface of the flame, so that a more perfeet combustion of the oil-vapors at the inner surface takes place, which could not be attained in the samedeeree in the central-draft lamps, owing to the insul'iicient supply of heated air to the inner surface of the flame.
llaving thus described myinvention, lelai m as new and desire to secure by Letters Patent- The combination, of a fixed central-draft tube, A, provided with inwardly-projecting studs f, a base-ring, l supported. on said studs and provided with an interior scat, f", with see'mmttal openings f, and with a diametrical U-shaped yoke, (4%, having a soclmt, 9 a spi'mlle, G, supported at its lower end in said socket, and provided in its upper end with a shoulder, g, a draft-cone, l supported on the interior seat of said baseline, and a detlector, G, provided at its lower end. with, a perforated socket, g, which receives the upper end 01: said spindleand rests on said shoulder thereof, substantially as described.
In testimony that I claim the foregoing as myinvention I have signed my name in preseneeof two subsm'ibing witnesses.
