SPECIFICATION forming part of Letters Patent No. 291,630, dated January 8, 1854.

Application tiled April 25, 15H22.

To @ZZ whom, it may concern:

Be" it known that we, WALTER SCOTT, of Hoosic Falls, in the county of Rensselaer and State of N ew York, and Mosns W. MaNwAu- ING. of the city of Bridgeport, in the county of Fairiield and State of Connecticut, both citi zens'of the United States, have invented certain new and useful Improvements in Sell'-` Extinguishing Lamps, of wliichtlie following` is a specification. i

Our invention relates to a sel f-extinguishing lamp; and the object in view is` to provide ai C forming a part hereof, Figure l is a side clevation, 'partlyin section, of one form of an embodiment of our invention in a lamp, looking toward the broad side, oi' the wick-tube. Fig. 2 is an elevation, partly in section, ot' the same, looking toward the narrow side or edge of the wicletube. Fig. 3 is a planet' the lamp with the top removed. Fig,4t is aperspcctive of the under side of a portion,ot' the top andi the mechanism attached thereto, and Fig. 5 is a modified arrangement of details. Fig. (i is another modification.

Like letters indicate like parts` in all thel figures.

A represents any suitable burner, having connected with the wick-tube extinguishing devices, which in this instance consist of two pivoted half caps or wings, AQ adapted to be closed over the wick B, to extinguish the flame thereof, by raising the Wire At.

So far as our present invention is concerned, We neither claim nor restrict ourselves to the form of extinguisher herein shown, but may (No inodelJ adapteuriueanstooperatewithauythrniot'ext 5oV i tinguisher, whether it is operated by devices which niove in vertical or other directions.

C represents the Outer or niaiu oil receptacle or body otl a lamp, and the saine maybe of any desired conl'bii-matiou.

./Vithin the body C is located and arranged, it may be in any suitable manner, a separate float-able reservoir, l), ol' such cfnistruction and relative size to the body ot' the lamp as to perinit oil to surround and to enter the saine, and 6o to` retain such portion of oil as shall enter therein, and as said oil is eonsruned by the burning thereoi'to gradually rise in and upon the surrounding oil in the body oi" the lamp,

voir may be utilized to actuate any suitable mechanism interposed between said reservoir and the extinguisher, to operate the same so as to put out the iianie ol the lamp. ln this 'whereby the movement ot' the tloating resei'-, 6 5

insta-nce, to illustrate one l'orni ot' an enibodi- 7o ment ot' our invention, the mechanism eniployed to convey the niotion ot' the floating reservoir l) to the extiiignisher-operaling device Ai comprises a vcrtically-arranged pushi bar, 1G, which passes through a guide-tube, f, 75

secured to the cover or top F OlA the lmnp-body l (l. To the under side ol" the cover or top is scoured any desired counterbalanced or spring locked pivoted lever, as @which presents its free end downward toward the i'loa-ting reser- 8f:

`Voir in such a manner that when the latter` rises sufficiently high, by reason ot' the consuinption ot' oil therefrom, the ibruiei; is forced against the bar E and raises it against the i extinguisher-operating device A2.

As shown, the lever G consists of a wire bent at one end to increase its contacteurfaces, and secu red at its o p posite end to a plate, g, one edge ot' which rests in notches formed in the edge Ot' studs or brackets f/, secured to 9o or formed on the top F, the opposite edge of said plate being connected b v a spring, H, ari ranged in line with Aand secured in advance of the free end ol the lever A. portion of said edge of the plate g is bent to forni a stop, g?,

which determines the position oi" the free end of the lever when in a locked position, as when the lamp has` been filled and its push-bar E Q senese vface ot' the top F, and the spring` il' is at that time so disposed as to exert its strain ina line above the Apiveted edge ot" the lever-plate g, and thus hold it slightly in a locked position, so that a lightt'oree exerted upon the depressed free end ot the lever will change the position of the plate, in which position the spring` exerts its strain in a line below the pivoted edge of. the plate and throws the free end ol" the lever forcibly upward against the lower end of the depressedpush-bar, and itin tnrnist'orced against the extinguieher-operating device A3. In this instance a step or projection, l', is formed or located on the i'loatinp` reservoir, so as to come in contact with the l'rec end ol' the lever; but, if desired, said i'ree end ot' the lever may be arranged to be operated by the bot-tom or a side wall ofthe Heating reservoir.

It may bedesirable to connect the floating` reservoir to the body oi'thelam1' in suchmanner as to retain it centrally therein, and yet permit 0f its rising` and falling,` for the purpose described. Uertain means ot' connection are herein illustrated, a-nd comprise pivotal links or hails J, arranged en any two sides of the body and iioating reservoir, and adapted to operate after the manner ot' a gimbal-snpport. The pivoted ends j of' the bailsl'ieingilr serted in slots j, 'termed in the walls oi' the floating` reservoir, permits vert-ical and prevents undue lateral movements ot' the same. lf desired, aspring, K, may bcinterposed between t-helbottoms ot' the lamp body and reservoir, for the purpose ot' conliter-balancing the weight et' the latter, in order that its rising` shall dep,end more :l'ully upon the quantity of oil consumedtherefrom, and thus tend to a more accuratepredetermi nation ol" thelengt-h oi' time which the lalnp shall be allowed to burn before being,` autoii'1:'1t1ic;,lly extinguished.

Other connect-ing;` means between the body and reservoir will readily suggest themselves t to a person skilled in mechanics, and wethere fore do not limit oursel ves to those above described; and, as above indicated, other means or details oi' motion-conveying devices may be interposed between the iloatinc` reservoir and the extingnisher-operating device.

As shown in Fig. 5, the push-bar l l .may be connected to a horizontal lever, G, pivotcd to the top F, held normally by a spring, il, against a stop, y2, on a secondary pivoted le- Ver, y, the i'ree end ot" which is projected over the iloating reservoir, l), sothat when it rises by consuml'itipn oi" oil therefrom. the lever G is released iren'i` the stop g2, and is iorced by the spring` to raise the bar h, as heretol'ore set forth. Furthermore, a weighted lever, G, as' shown in Fig. o', may be thrown over its center ot' suppolrt (by the reservoir D or a step,

I, therein while it is ascending) and upon a secondary arm, which shall raise the lever G,

as aforesaid, and various other modified arrangements el' motion-conveying devices may be employed, and are deemed as coniprehended by ourinventiou. It'desired,aiilling-hole, may be provided, but this is not essential, as our invention in no manner affects the removability ofthe burner l'or lilling purposes.

To prevent undue splashing of oil within the reservoir, and to retain the desired quantity of oil against displacement by swaying, jarring, or any ordinary nnlcvel disposition of the la.mp,we provide the floating,` reservoir with a cover, L; but it is perforated centrally at Z t'or the passage ofthe wick.

Having described our invention and its operation, what we claim isl.. A lamp provided with a floating,` rcser voir, an extingusher, and intermediate motionconveying devices, whereby the consumption ot' oil from the reservoir causes it to rise and extinguish the vl'l ame of the lamp, substantially as herein set i'orth.

2. In a lamp, the combination of a floating reservoir, an extinguisher, and'intermediate extinguisher-operating devices, substantially as specified.

3. ln a lamp, the combination of a floating` reservoir, an extingnisl'ter, and an intermediate spring-locked or equivalent extinguisherdevice-om-irating` lever, substantially as specitied.

4. rihc combination of a lamp-body and an internal lloat-ing reservoir with pivoted connecting-hails, to maintain it in proper relation tothe extiluruishing mechanism, substantially as specified.

5. The combination, with a lamp, C, provid-ed with extinguishing devices A A2, ot' a tloati ng reservoi r, D, and an intermediate pushbar and pi voted lever,G, substantially asspecitied.

o. The combination of the pushbar E, lever G, plate r/, brackets g', stop y, and spring ll, substantially as shown and described.

7. The combination of the lamp-body C, reservoir l), and bails J J, pivotally secured to the body and to the reservoir in slotsj therein, substantially as shown and described.

8. The combination et' the lamp-body (l, reservoir D, havi ne' a centrally-perforated cover, L, and bails .T J, substantially as shown and descrilml.

lhe combiuat ion ol' the lamp-body C, reservoir l), having;` step I, lever G, push-bar E, and burner A, and operatingrod A, subst-antially as shown and described.
