SPECIFICATION forming part of Letters Patet'No. 381.1275. dated Aprilv 17, ,11888. i

Application fuga December s, 1ste. 'seriainmsaoaa (Nummer)v d t To all whom imcty concern:v v

Be it known that I, DEXTER W. PARKER, of Meriden, in the county of New Haven and State of Connecticut, have inventeda new and useful Improvement in Lamp-Fixtures; and I do hereby declare that the following isafull, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this application.

y My invention relates to certain new and useful improvements in that type of hanginglamp fixturesin which the lamp,v together with f vzo `my invention relatesto make and use the in 'none that yI know of has the entire construction or the combination of devices employed been such as to accomplish efficiently lall the ends ldesirable in such a fixture.

I propose by my improvement to provide for use a fixture ofthe typereferred to which, while it shall be equally simple and economic of manufacture as those heretofore made, shall be more efficient and desirable in. its operations; and to this main end and object my invention consists in the novel construction or combination of devices, which will be hereinafter more fully explained, and which 'will be most particularly pointed-Outland defined in the claims of this specification.

To enable those skilled in the art to which same,I will now proceed to more fully describe the same, "referring by letters to the accompanying drawings, which form a part of 'this specification, and in which I have shown my invention carried out in that form in which I have so far successfully practiced it, and which v is about the best form now known to me.

In the drawings, Figure 1, represents in elevation alamp-fixture made according to my .finventiom and'having its movable parts adl j usted to a position such as would beoccupied ,1'

vby them while theburner`of .thelamp might' bellighted. Fig. 2 is a view showing the same fixture, but withY they parts which are' relatively adjustable moved to the positions necessary to place them in forthe purposeof lighting the burner ofthe lamp, either by the removal and replacementy of the chimney or by the .removal and. replacement after lighting of the chimney,-burner, and reservoir orV lamp-body.

l In both views the Samepart win be fourni designated by the sameletter ofy reference.'`

` Inclosed Within the canopy or ceiling-plate C of fixtures ofthe type'shown ,isl a spring l,

suspension-drum, E,`which is suspended from',- Q.,

the ceiling-of the apartment in the usualmanner, and which is formed or provided,asusu`al, with-a double run of chains, F and G,whic`n pass fromv the periphery of the drum,respect ively,jover anti-friction pulleys a andi in the manner wellknown, 'and descend thencel to va cross-bar or ornamental metallic cross-head, A, Yto either end of which;` the said chains are securely attached, all as .plainlyshown in theY drawings.' Y,

j Within the metallic cross-head or frame l yare mounted uponsuitable pivots, so as to 'turn freely, and 'near either end of said cross-bar, two small pulleys or anti-friction wheels,bb, over which pass a double, run of chains, c o', the outer 4 end of each-of which chains is securely attached to a metallic ring or annular` flange-plate, d, the inner ends of said chainsv being secured, as shown,l toj the upper'endof the lamp-frame e. v j formed or provided with a disk-shaped base .or

bottom, f, provided, by preference, with accu- 'y -V trally-depending 4 ring or otherornamental de-v vice, m, which conveniently servesthe pur! pose of theuser of the fixture in pnllngdown or otherwise adjusting the parts-thereoi',and said lamp-frame is also in the case shown .pro-

v vided with a short upwardly-projectinglcyling95 drical portion or vertical iiange, K, within Y whichl is seated a cylindrical transparent or translucent shade, j, (when the parts ofthe fixture are adjusted for the use ofthe light as shown atFig-.1,)the upper end of which shade The said lamp-frame e is"` is valso surrounded exteriorly of the chimneyl j is preferably turned over or has an outward-` ly-projecting flange, which rests upon or en-v bar A, as plainly indicated at Fig. 2 of' the drawings.

gis the reservoir of an ordinary kerosenelamp, while h represents the burner ot" the lamp, and i the ordinary glass chimney.

When the parts,whieh are relatively 'adjustable, are all set as shownat Fig. l and: the-v "for the purposes of either extricatin g the chimcross-bar A placed at suclilan elevationas will bring the lamp to the' desired height for use, the fixture, it will be seen, will present the def sired aspect and resemble 'in appearancea'nd serve the vpurposes in use of the usual hall or 1 other fix/tures in which theburning'lampis provided with the usualchimney, Vand which drical form and is seated or rests at its'lower end upon the bottom of the lamp-frame and within the surrounding and steady cylindrical the chimney or the lamp andburnerg'and h,

portion K, but which shadefor globe may,of

course, be of frustuminal or some other shape,

such as not to require the use or presence of the portion lc ofthe-lamp-holder, landsuch asV not to have its baseV in contact withthelatter. j

Whenever it` may be desired to remove either together with the chimney, forl the purposeof trimming and lighting'the burner, it is only necessary to take hold, preferably, of theA ring m of the lamp-holder and pull the latter down until the stops l shall have come into contact with the cross-bar A of' the fixture; when the relationship of thelamppr'oper and its attachments with the surrounding shade or globe will be such, as shown at Fig.` 2,-as to permit the ready removal of the parts necessary to be d'own in opposition to the spring-drum supporter E, for the purpose of lengthening out the depending portions of thechains F and G,

so as to set the cross-bar A in a lower position,

and thus cause the lamp-frame, with its appurtenances and the adjustable surrounding globe or shade, (when these parts shall have been relatively readjusted,) to occupy a lower position whenever it may be desired to have the light at a lower elevation, and that by slightly pushing up on the adjusted fixture the cross-bar A will be drawn up by the automatic spring hook or drum device E, for the purpose of having the light at any higher elevation that may be desired.

-It will be seen that while my improved fixture possesses all the ingredients for not only setting the lamp and its appurtenances to burn at various elevations, as may be required, and for also adjusting the burner and its chimney relatively to the surrounding globe or shade,

ney, or the chimney andburner also,(to light Vthe lamp,) and replacing the parts in their normal'or operative relationship, the whole structnre is exceedingly simple and not liable to any derangement ofits parts during any of the operations necessary for effecting the adjustments alluded to.

jHaving now so fully explained the construction and'operation of my improved lamp-fix- "tur'e that those skilled in the art can make and 'use the same,what I claim therein as new, and

desire to secure by LettersPatent, is

I 1. In combination with a suitable springdrum device for properly counterbalancing the entire weight of the suspended parts, a suitable cross-bar or frame-like device, A, suspended from said spring-drum device by a double run of chains or cords, a pair of suspension-chains depending from said cross-bar in the manner specified, a globe or shade suspended from one set of the ends of said pair of chains, and a lamp-holder adapted to support Vor cords, F and G, and a spring-drum supporter, E, the whole arranged and operating together substantially as and for the purpose hereinbefore described.

In witness whereof-I have hereunto set my hand this 2d day of December, 1885.

DEXTER W. PARKER.

In presence of FREDK. PEAsE, RALPH A. PALMER.
