SPECIFICATION forming part of Letters Patent No. 519,851, dated May 15, 1894.

Applica'll filed September 20, 1889. Serial No. 324.500. (No model.)

To all wir/0m, it may concern,.-

Be it known that I, EUGENE F. TRENT, of Jersey City, in the county of Hudson and State of New Jersey, have invented a certain nettr and useful Improvement in Lamps, of which the following is a specification.

I Will describe a lamp embodying my improvement and then point out the novel features in the claims.

In the accompanying drawings Figure l is a central vertical section of a lamp embodying my improvement. Fig. 2 is atop View of the same. Fig. 3 is a horizontal section of the upper parts taken at the plane of the dotted line no Figi. Fig. 4 is a perspective view of one of a number of fingers which serve to center the ou ter air distributer, the onter detlector and thechimney. Fig. 5 is a side view of a Wick carrier. Fig. 6 is a top vlew of the same. Fig. 7 is a side view of certain parts of the burner. Fig. 8 is atop view o f the parts shown in Fig. 7. Fig. 9 is a sectional elevation of certain other parts of the b urner. Fig. 10 is a top view of a Wick carrier of moditied construction. Fig. 11 is a sectlonal elevation of certain parts of a burner of modified construction. Fig. l2 is a horizontal section taken at the plane of the dotted line y y, Fig. ll. Figs. 13, 14. and l5 are enlarged views of certain parts of the lamp.

Slmilar letters of reference designate corresponding parts in all the gures. A designates the fount of the lamp, which 1s represented as being made of sheet metal and as provided with a central tube B. As here shown there is a iiaring cavityo., at the base of the tube B, and this cavity forms a funnel-shaped mouth which will be advantageousfor directing air into the tube B. It

Will be observed that the reservoir is pro-` vided at the center of its top With a mouth o'r collar ct', adapted to receive a burner and that the tube B terminates approximately on a level with the top of this mouth or collar. The tube B is intended to serve as a central draft tube for a burner which is made detachable from the lamp fount. Its coaction With the burner can be more perfectly explained after a description of the burner shall have been given. As here shown the fount is supported upon a pedestal C, which is perforated at the bottom so as to admit air within it and has inside it and beneath the tube B, a drip cup K. The fount A, as here sbown,l1as a partition a2, extending horizontally acrossit about midway between the top and bottom. This partition is represented as made of perforated material, as, for instance, perforated sheet metal. The partition has a central opening of suiiicient size to allow the extension through it of all the centrally located parts of the, lamp which should pass below it. In the present instance this opening simply serves to permit the extension of the wick beneath the partition. Beneath the partition a2, the fount is traversed by a number4 of radial partitions as,

which extend from the outer Wall nearly to -V the center and are made of perforated material,preferably perforated sheet metal. Above the partition a2, the fount is traversed by a number of partitions at, which, like the partitions a3, extend from the outer Wall inwardly nearly to the center. Preferably these partitions d4 will not bc in line with the partitions a3, but will occupy positions intermediate of the partitions a3. The partitions a4, like the other partitions, may be made of any suitable perforated material.

By the partitions described I am enabled to divide the fount into a number of compartments which, while they have free intercommunication, serve to check the movement of.

the oil Within the fount and thereby reduce the liability of the spilling of any of the oil. A fount having compartments of this character is peculiarly adapted for use on any article in motion, as, for instance, in vehicles or marine vessels. The fount is shown as provided with a filling well a5, made of perforated sheet metal and having its mouth closed by` a removable cap. In it is an annular iioat whichl may consist of a piece of cork. An annular float is desirable because under the influence of a moving column of oil within the Well it will not rock but will be rotated.

D designates a burner having a body d, which may be made ot sheet metal and has a central boss which fits in the mouth or collar a', of the fount. In the present instance the boss is represented as externallyscrewthreaded and the mouth or collar as internally screw-threaded for effectingthe en- IOO v lar a' gagemen'to'fthe burner with the fount. The body is' shown as closed by acap d. Secured 1n the body are two cylindric shells cl2, d3, whlch are arranged the latter concentrically within the former at a sufficient distance from 1t to accommodate arwick. TheA outer shell d2, 1s secured by solder, or otherwise, to the burner body d, and the inner shell d3, is secured to the outer-by upright plates dvextending diametrically between the shells. These plates d4 (see Fig. 2), may be secured by solder or otherwise, to the shells. These plates need not extend for a great distance lengthwise of the shells. When the wick tube thus constructed of two shells united by 'dlametrica'lly extending plates, it is, of course, `only adapted' fora wick made in two' sections, 0r, for a wick. .whose lower portion lsxdivided. The inner shell d3, of .the burner, extelndsidown over the upper portion of the ,in the fount,l fitting said tlyibeclosely. tube B,Kwill form a' guide by which thev SCIfewjngy of the burner into the mouth or colyof the'yfount, will be facilitated.` Air o, l(1111:through thetubfe B, will pass int0`` inner. shell d?, of, the burner and ascend through the latter to the dame. It will be' spread outwardly by spreaders S S2, .support-V edbyapos't or pedestal sustained b`y spiders con'nectedV with the inner shell.

`` E,designates thewick carrier. As repre-A sented ,inv thewprincipal example of my improvenent, more particularly in Figs.' 5 and 6, itycopssftslofaba'nd of sheet metal .having ai number of V*- s'haped incisions, the metal bounded by which is pressed inward to form prongs adapted to engage with the Wick. It

ybe Seenthat this ring has L-shaped'indisions yinafde at one end, in the present instance. at the lower end, and that the metal bounded by these incisions is turned inwardly toform projections e, constituting partitions which indicate the position which the edges off thesections or portions of wick should o"c' cupy and for facilitating the proper insertion o f said sections or portions. These projections e `are approximately in line with the plates d, extending diametrically between the two shells of the Wick tube. On the exteriorlof the band are pins or projections e',

which pass through vertical slots located dia inetrically oppositeV each other in thellpl'er ,portion of the outer shell d2, of the wick tube; so that they may be moved up and down yto" elevate and lower the carrier and with it the wick.A .t

g oqtsiuethe cuter shell d2, 'of the' wick tube, isla tube F', having spiral slots into which the' projections e extend. This shell is free to rotate to cause its spiral slots to elevate and iowervthe pins and hence the wick carrier and At vthe lower end this tube F, loosely surrounds an upwardly turned ange with which the top or cap d', of the burner bodyd', is provided,` and from its lowerend extends a flange f, the outer portion of which of the wick tube;

is depressed to form al shoulder f', and a hand-piece fwhichmay be grasped to effect the rotation of the tube. It will be seen that the top or cap d', of the burner body has a shouldered portion corresponding to the shoulderff and receiving the latter around it in such a manner as to aid in centering the tube F. The upper end of the tubeF is provided with an inwardly and downwardly extending fiange f3, which may be Vmade by turning the upper edgeof said tube inward and downward. The upper end of the outer shell d2 of the wick tube is turned outwardly into contact with the interior of the main portion of the tube F and the `flange f3 overlaps it. The iiange f3 in combination ywith the outer shell d2 of, the wicktube", forms outsidel the wick, a' belljnnouth or funnel, which Wil-l catch any' oil over'lievi/ing4 from the exterior of the `Wick and convey it back into the wiel; tube.

The upper outturned edge of the outer y,shell of the wick tu'bein connection with, the ange f3 also aids in' centering the` tube MF relatively to the outer shell of ,the vificlry tube.

` The tube'F is only held in place by friction and hence may with its flange* f and handpiece f2, be' lifted od the. capo'r top` 0f the burner body and outer shell of thewick tube.

In the iiange f, opposite the spiral slots, radiallyrextending slots are provided and these communicate with the spiral slots, so'as toena'ble the' projections e of the wick carrier, to enter the spiral slots. AI desire to call attention to the fact that the upper edge of.. the

. tube F extends above the outer, shell of the wick tube and forms the tip of the'outer wall G designates the airdistributer, here shown as made'o't` cyliudric form with an expanded base portion gfand an expanded top portion g?. The expanded vbase portion fits around the shouldered portion f of the iiange fappended to the tube F. On the shouldered portion f are a number ofbossesl or projections f4. These titv within the expanded base portion of the air distributer Gr, and center the same. i On the shoulder fare other projections or bosses f5, which are lower than the projections f4. The expanded base' portion of the air distributer has a corresponding number' of cavities which may interlock with these lugs f5, `so that any rotary movement of' simply lifting it oir the flange of the tube' F.

At the upper end of the air distributor G, are a number of fingers' lLconsisting of body portions h', prongs h2l adapted to extend through holesin the air distributer, horizontal portions h3, downwardly extending portions h4, having a bearing inside the air distributer,

ICO

ter at the upper portion.

tongue portions h5 constructed to bear against the tube F, and upright portions h6 serving to hold in place a deflector I, resting at the lower edge on the horizontal portions h3, and to sustain a chimney. The fingers may be secured to the air distributer by solder, or otherwise. In the present instance it will be seen that the downwardly extending portions h4, bear in a recess located at the upper end of' the air distributer. When they have such a bearing it will be sufficient to fasten the fingers merely by upsetting or riveting the ends of the prongs h2, outside the air distributer. These fingers aid in centering the air distributer relatively to the tube F and consequently relatively to the wick tube. They also serve to support and center the defleetor I. It the prongs h2, are left sufficiently long, they will serve to support a shade holder or globe holder. the lower part of a shade holder or globe holder, J, supported by the prongs.

I-Iaving now described the principal example of my improvement, I will describe the parts of modified construction illustrated by Figs..l0,1l and l2. In the burner illustrated by these figures, the bottom of the inner shell, di, is closed, the body, d, of the burner is perforated and air is admitted from the interior of the body to the interior of the inner shell cl3, by horizontally extending tubes d10, of which there may be any suitable number but are here represented as being only two in number. The wick carrier, E, instead of having merely two prongs e, has two pairs of` prongs. They may be made in the same manner as the prongs e, tirst described. The reason why two pairs of prongs instead of two prongs are here used, is because the edges of the sections or portions of the wick must be separated to straddle the tubes d10. The inner shell, d3, of the wick tube is shown as extended inwardly or reduced in diameter near the tip. The outer shell, d2, is turned outwardly and against its upturned edge fits the tube F. The tube F, is reduced in diame- It will be understood that the upper portion of the tube F, forms a part of the wick tube in this example of my improveinent'as well as in the other example of the improvement. The reduction of the shell cl3 and tube F, decreases the circumferential space in which the tip ot the wick is accommodated, to such an extent that the side edges of the wick sections or portions will come together and form a continuous wick at this point. 'At the upper extremity the tube F, is turned outwardly so as to form a bell mouth or funnel, by which any oil overflowing from the tip of the wick will be conveyed back into the wick tube. The tube F, is provided at the base with a flange f, a shouldered portion f', and a hand-piece f2, asin the first example of my improvement. It

also has spiral slots engaging projections e', extending from the wickcarrier through vertical slots with which the shellcl2 is provided.

In Fig. l, I have represented- To prevent a frictional bearing of the adjacent top edges or corners of the wicks, when forced upwardly within the reduced portions of the wick tubes, I provide wings at the upper end of the tube d3. Said wings (i12 are opposite each otherand stand outwardly or at right angles to the longitudinal axis of the tube. As before stated these wings prevent the corners of the wicks touching each other and also form guides to keep the upper portions of the wicks in an upright position.

In my pending applications, Serial Nos. 257,524 and 323,057, I show and claim wick raising mechanism similar to that shown hereimbut in this application I do not claim the wick raising mechanism in the combination as claimed in the applications above referred to.

What I claim as my invention, and desire to secure by Letters Patent, is y l. In a lamp, the combination with the tount of ahorizontal perforated partition and two sets of radial perforated @partitions respectively above and below the horizontal partition, substantially as specified. y
