FLUID-BURNING LAMP.

Specification of Letters Patent.

PatentedSept. 19, 1916.

Application filed May 28, 1914. Serial No. 841,500.

To @ZZ yZIJ/wm t may concern Be 1t known that I, VINCENTE SZAMIER, a citizen of the UnitedStates, and a resi- -dent of Terryville, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Fluid-Burning Lamps, which improvements are fully set forth in the following specilication.

This invention relates to improvements in lamps, and more particularly to lamps of the fluid-burning type and each of which is capable, upon being upset, of extinguishing' its own flame; and its object is to provide a lamp, lantern, or the like, of the character above indicated, which shall be simple and comparatively inexpensive as regai'ds its construction; durable, eflicient and reliable in practical service; which shall embody features of construction whereby is insured, upon the same being upset, the extinction, automatically, of the flame thereof; and which shall possess certain well-defined advantages over prior analogous constructions.

The invention consists in the combinations, details and parts whereby, together with the novel disposition and relative arrangement of said parts, the attainment of the foregoing object is rendered practicable, all of which will be hereinafter more specifically referred to and set forth in the appended claims.

The invention is clearly illustrated in the accompanying drawing', 'wherein-u Figure l is a fragmentary side elevation, partly in section, of a lamp embodying my said improvements. F ig. 2 is a fragmentary plan view of same, the cover for the ti'ipmechanism housing being removed. F ig'. 3 is a view showing in side elevation and detached the wick-casing', certain minor parts immediately coperating' therewith being shown in vertical section. Fig. 4 is a view showing in perspective and detached the trip-mechanism which I ,purpose making use of, together' with certain parts provided for cooperation therewith, the scale being somewhat enlarged. VFig. 5 is a bottom plan view of the trip-mechanism housing'. Fig. G is a view showing' in perspective and detached the operating', gravity lever made use of.

Having reference to the accompanying drawing', wherein similar reference-characters denote like parts throug'hout the several views, I, in carrying out my invention, make use of a fount 2, as of a lamp, lantern, or the like, the same being adapted to contain a combustible fluid, as kerosene, and being provided with a burner 2, in the usual-manner, said burner being' provided with the usual upstanding wick-casing 2, upwardly and downwardly on which rides a flameextinguisher. As here shown, said flameextinguisher comprisesa flattened sleeve 3, freely surrounding the casing 2, having' a downwardly extending arm 8 and provided with an upwardly extending flap 3, the latter having a rocking action, as at the opposite points 4, 4 and being' elastically controlled, as through the medium of a leafspring 4,'attached tothe sleeve 3 by means of rivets 5, or other suitable fasteners.

The spring 4 tends at all times to rock and cause the iiap 3 to span and close the sleeve 3, said flap assuming such sleeve-closing position under each due upward thrust of said sleeve and receding therefrom under each downward movement of said sleeve, all as will be readily understood,A since the construction thus far described is old and well known in the art.

5 denotes a main lever which extends radially through the wall of the burner 2, by way of an opening 6 formed therein, and operates on a pivot 5, the exposed portion of said lever affording a finger-piece 6 and a stem 6' depending rigidly therefrom, while the inner or concealed portion thereof extends to and suitably engages the arm 3', preferably by freely entering an eye 7, (Fig. 3), formed in said arm.

AAn elastic controller, as the extensile spiral spring 7, is interposed between the lever 5, intermediate of its fulcrum 5 and the arm 3, andv any suitable fixed part thereunder, as the base 7 of the burner 2,. the tendency of said controller being, at all times, to thrust upwardly that portion` of the lever 5 lying thereover, thereby causing, through the mediumv of the arm 3, a like upward movement on the part of the sleeve 3,- along the wick-casing 2, and sullicient vto bring the flap 3 somewhat upwardly beyond the top edge ofthe adjacent Wall of the wick-casing aforenamed, thereby permitting said flap to dulyrock, under the impulse of spring 4, into the position the same assumes, (Eig. 8) for closing the top of the sleeve aforenamed. It will be understood that when the flap 3 occupies its lastnamed position, air-circulation proper for the maintenance of the flame, as customarily induced at the top of the wick-casing` 2, is effectively checked, with the result that the flame aforenamed is accordingly extinguished.

The stem G supports at its lower end a vertically swinging clevis S, which in turn supports a horizontally swinging tongue S,'

the latter affording opposite detent- shoulders 9, 9, which permit the same to be temporarily grasped by opposite jaws 9, 9 working, respectively on pivots 10, l() jointly controlled by a bowed, leaf-spring 10, and all supported by a platform 11, riveted, or otherwise attached, to the burner 2, exteriorly thereof, and as clearly shown in the drawing.

The springs 10 tends at all times to elastically keep the jaws 9, 9, closed, the same being spread apart by the tongue S, and exerting thereon, in cooperation with the detent- shoulders 9, 9, thereof, and only upon lever 5 being retracted against the tendency of its controller 7, aV temporary holding grasp, as will be readily understood, said tongue being freed from this grasp, to accordingly release the lever 5 for coperation with the sleeve 3, upon said jaws being duly spread apart, or either thereof moved against the tendency of the spring controlling the same.

The elastically controlled jaws aforenamed, and parts more or less immediately cooperating therewith, constitute trip-mechanism which I purpose interposing between the lever 5 and a gravity device which I purpose making use of in this instance, which will be hereinafter described, land whereby said jaws, or either thereof, may be duly actuated, automatically, to release the tongue 8", when held thereby, and upon the lamp, lantern, or the like, to which my present improvement may be applied, being tilted more or less out of its normal upright position, the construction thus far described, save the gravity device aforenamed, being in all essential details and mode of operation, substantially identical with that constituting the subject-matter of my co-pending application serially numbered 831,982.

As to the gravity device aforenamed, the same consists of an arm 11, which swings to and fro horizontally on an upstanding pivot 11, situated between the jaws 9, 9", said arm affording a downturned lip 12, which occupies, at all times, a position intermediate of said jaws, and, being positioned duly away from the pivot 11, is adapted to reversely actua-te either thereof, according to the direction in which the arm 11 may automatically move in practice, said arm radiating from the pivot 11 in any appropriate direction, and havingl mounted thereon at its free end a weight 12.

For positively locking the operating parts Liese?? of my present improved lamp, as against the tendency of the spring 7, I provide the stem 6 with a notch 12, and arrange for cooperation with said notch a minor lever 13, said lever working on a pivot 13, and adapted to be swung into and out engagement with the notch aforenamed, thereby locking or liberating, accordingly, the lever 5, together with all parts provided for cooperation therewith.

I prefer that the platform 11 be provided with opposite upstanding side-walls 1e', 1li', connected by an upstanding end-wall l-l, whereby is fo-rmed for the trip-mechanism aforenamed a general, open-top housing, the latter being provided, also by preference, with a removable top-plate or cover 15; and in practice, where such cover is employed, the minor lever 13 may be pivotally attachech thereto, at the underside thereof, as clearly indicated in the drawing.

It will also be noted that, to provide due clearance for the lever 13 and the gravityarm 11, the side-walls 14e, 14 are suitably cut away, as likewise clearly indicated in the drawing.

In operation, should my present impro-ved lamp be upset, or even partially tilted out of its normal, upright position, the parts being primarily locked, as through the medium of the jaws aforenamed lockingly engaging the tongue 8, as hereinbefore explained, and wick 8 maintaining a flame at its top, the arm 11, through the medium of the weight 12 carried thereby, will automatically move in a manner to break, through the medium of its lip 12, the locking engagement of said jaws with said tongue, thereby releasing the latter and so permitting Vthe lever 5 to respond to spring 7, with the result that such upward movement on the part of sleeve 3 is induced as will permit the flap 3 to undergo proper movement for closing the top of said sleeve, thereby effeotually extinguish.- ing the lamp-flame, this all being accomplished automatically and very promptly upon the lamp being upset, or measurably tilted out of its normal upright position.

It will be seen that my present fluid-burning lamp is well adapted for the purposes for which it is intended, and further that the same may be modified to some extent, particularly as regards the specific character of the trip-mechanism made us of, the specific character of the gravity-arm availed of, and as regards various minor details of the general construction, without materially departing from the scope of the claims hereto appended.

1. In a lamp or the like, the combination with a wick-casing having a spring-controlled flame-extinguisher mounted to slide thereon, of ay pivotally disposed gravity-arm, freely movable horizontally with respect to said wick-casing, and trip-mechanism, the latter interposed between said flame-eXtinguislier and said gravity-arm, adapted to lock the former against the stress of its controlling spring, and, thereafter, to release the same for response to the stress of its controlling spring, under any automatic action on the part of said gravity-arm due to the tilting of said lamp out of its normal, upright position.

2. In a lamp or the like, the combinationy with a wick-casing having a flame-extinguishing device mounted to slide thereon, of a spring-controlled operating lever, whereby said flame-extinguishing device is duly actuated, a pivotally disposed gravity-arm, freely movable horizontally with respect to said wick-casing, and trip-mechanism, the latter interposed between said operating lever and said gravity-arm, adapted to duly restrain the former against the stress of its controlling spring, and, thereafter, automatically release the same for response to the stress of its controlling spring, under any action on the part of the aforenamed gravity-arm due to the upsetting of said lamp, or the tilting' thereof out of its normal, upright position.

In a lamp or the like, the combination with a wick-casing having a flame-extinguishing device slidably mounted thereon, of a spring-controlled operating lever whereby said flame-extinguishing device may be actuated, said lever affording a depending part having a tongue pivotally attached thereto at its lower end, a spring-controlled jaw engageable by the tongue aforenamed for restraining said operating lever against the stress of its controlling spring, and a pivotally disposed gravity-arm, the latter freely movable on the pivot which supports it, and when moved by its own gravity, as by the upsetting of said lamp, -or tilting thereof measurably out of its normal upright position, adapted to automatically actuate said jaw in a manner to release from engagement therewith, the tongue aforenamed.

at. In a lamp or the like, the combination with a wick-casing having a spring-controlled flame-extinguisher slidably mounted thereon, of a pivotally disposed arm, freely movable on the pivot which supports it and horizontally with respect to said wick-casing, and trip-mechanism, the latter vinterposed between said {lame-extinguisher and said arm, adapted to lock the former against the stress of its controlling spring, and, thereafter, to release the same for response to the stress of its controlling spring, under any action on the part of the arm aforenamed due to the upsetting of said lamp, or the tilting thereof out of its normal, upright position, said arm being provided with a weight at its free end.

5. In a lamp or the like, the combination with a pivotally disposed, spring-controlled operating lever having a stem depending therefrom, of a notched tongue, pivotally attached to said stem at the lower end thereof, and a pivotally disposed, notched jaw, the latter freely movable horizontally with respect to the stem aforenamed, and coperating with said tongue in a manner to restrain the operating lever aforenamed against the stress of its controlling spring, and, thereafter, to automatically release said lever for response to the stress of its controlling spring, upon said lamp being upset, or tilted out of its normal, upright position.

6. In a lamp or the like, the combination with a wick-casing having a spring-controlled flame-extinguisher slidably mounted thereon, of a part movable automatically Y under its own gravity and horizontally with respect to said wick-casing, and trip-mechanism, the latter interposed between said flame-extinguisher and lsaid part, adapted to lock the former against the stress of its controlling spring, and, thereafter, to release the same for response to the stress of its controlling spring, under any action of the part aforenamed due to the upsetting of said lamp, or the tilting thereof out of its normal, upright position.
