IMPROVEMENT IN LAMPS..-

Specilication forming part of Letters Iatent No. 46,171, dated .February v1865.

To all whom it may concern:

Be known that I, JAMES IvEs, of Mount l. Carmel, in the county of New Haven and State ot' Connecticut, have invented a new and useful Improvement in Lamps; and I do hereby declare'that the following is a full', clear, and exact description of the same', reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a side elevation and partial seetion of the'lamp as adjusted for being lighted, trimmed, or anyoth'erpurpose. Fig. i2 is a side elevation ot' the same as adjusted for the purposes ot'being filled, `cleaned,'trimmed,

or. lighted,.or for any other useful purpose.

Ihis part of my invention obviates the-neces sity of takin g either the g'lobe or chimney out of position, and its use willbe found very ad- .'Vantageous in my already-patented bracketlamp, as well as in connection with .ordinary v railroadlainps, coachlamps,and with lanterns which employ chimneys and globes;

My invention consists, second, in so suspending the lamp andthe chimney and globe that the former, by ybeing drawn down, throws up the latter-4i. e., chimney and globeand the about equal or superior weight ot' the chimney and globe serves as a means for bringing the parts back to their proper burning position after the lamp has been lled, trimmed,

cleaned, orlighted, as the case-inay'have rel`quired.\ This part of my invention gives double the amount'of spacebetween the lamp and chimney with half the length of movement usually made in the lamp or in the chimney, and the shade or globe itself answers as a weight to bring the parts together, thus dispensing with weights and cords, which, impai'rthe beauty of the arrangement.

My invention consists, third,.in the means shown for accomplishing the suspension of the lamp and chimney and globe, whereby stability, cheapn'ess, and a very perfect operation are attained.

- To enable others skilled in the art to make and use my invention, I will proceed 'to de- I scribe the same with reference to the drawings. I

A is an ordinarycoal-o'il lamp; B, an ordi nary shade orA chimney, and G an ordinary globe. D is a-.rimmed base or seat forth'e globe. In the center of this base a circular seat, E, for a co-ne, 'F, is formed,`as shown. Ihis cone is of any ordinary-formation, and between ity and therim ofthe seat E the glasschimney B is set, as represented.- The seats or base-supportsDE `are connected by narrow cross-bars or arms a c, so thatyno great amount of .obstruction to the downward 4 reflection of the light shall be elicited. The seat E is also open at bottom, so, as to admi-tv the wick-tubeof thc lamp `up into the'cone, i

as usual.,

G G are rods extending up' from thelamp .th rough the rbasefiD,and; np- .tdand loosely' thron gli asemieircular gn ard and stay-plata'll, f as represented. At bb these rods are bent so asv to form a stopv for controlling th'e downward I A movement of the lamp. y I Il are other similar rods extending upl from the base or seat Dot' the globe and chimney and fastening firmly to the stay-plate or collar H. From the ends of the rods G and I an endless chain, J,passcs up and is looped over a pulley, K, ot' 'a suspension bracket or bow, L. A similar chain, J', extends up from the ends ofthe rods G I', and is looped over a pulley, K', on the other end of the bow L, as shown.

-When the chimney is set in its seat, the stayI EI partly encircles it, and thus lessens the liability of the chimney being knocked out of place. rIhe weight oi' the globeand ehimneyis always to be about equal, to or greater than that of-'the lamp, so that the lamp, after being drawn down by hand, shall be-returned toits place by the gravity of the globe and chimney or greatly facilitated therebyv The operation of'the lamp is as follows: It y being suspended by its bow L upon a hook iii a hall or other place, the housekeeper has only to pull downward upon the lamp in order to get it to the position shown 'in Fig. l. The

descent of the lamp causes an ascent of both the globe and chimney, and a descent of the globe and chimney causes an ascent of the lamp.

It is a novelty among lamp-manufacturers und the globe, So 'asto have `the1n go up o r standstill together while the lamp is 'moved down or :Lwey from them. f What I Gleim as myinveutionnd desire to secure by Letters Jatent, is

1. 1A' combined globea fd lchimney bese orf seat, substantially s amd.;4 for thepurpsefet oljimliy tht'the movement ofthe lampdovnward `Will cause au upward movement. of both n'u'dilh tvhe nrtefI-believeto unite the ehimrleyff -illelrzllilimey :ind globe.,- s.ubstanlz'allyIesV nml `for the purposes set'forth.
