IMPROVEMENT IN GAsoLlNE loooKlNesroviae Specication forming part of Letters Patent No. 200,636, dated February 26, 1878; application led l y January 25, 1878.

To all whom it may concern: f

Be it known that I, HENRY WELLINGTON, of Green Point, county of Kings andy State of New York, have invented certain new and use-l ful Improvements in Gasoline Cooking-Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon. Y

Figure l is a sectional elevation of a stove constructed and arranged in accordance with my several improvements. Fig. 2 is an en-v larged sectional view of the connection between the vertical and horizontal circulationpipes, showing the method of constructing the valve-seat for the circulation-valve and of uniting the oil-pipe with the material of said seat. Fig. 3 is an enlarged section and elevation of the oil-tank or supply-reservoir, exhibiting the several improvements upon this por. tion of the structure. Fig. 4 is a plan or top view of the stove, illustrating particularly the arrangement and location of the water-circulating pipes. Fig. 5 is an elevation of the steam cooking chamber detached from the water-tank, a portion of the door being broken out to show the arrangement ot' cooking-pans or other utensils in said chamber. Fig. 6 is a section of the lower portion of the water-tank, illustrating in detail the position of the checkvalve placed over the mouth of the outlet water-pipe leading to the coil around the burner. Fig. 7 is an axial section of the improved burner, the two parts thereof being separated the better to show their construction, and the reservoir; to provide au improved chamber beneath the burners, which shall be capable of receiving the drip from the burners'or their connections without danger of communication Aof iiame with said drip after it enters the subreservoir 5 to so arrange a water-tank and circulating-pipes in connection with a gasolinestove as that said tank shall aord a supply of hot water, with auxiliaries necessary to steam cooking, and with attachments necessary to adapt this portion of the structure for successful use and easy manipulation under vall circumstances of general domestic operation; to provide a wind-guard for the burner which shall be secured to the-removable section of the top plate and detachable therewith, in order that the name may be protected, as in all similar contrivances, while at the same time the different parts of the burner may be reached without the usual difficulties; to soimprove the construction of the burner as to give a larger and better flame than has heretofore been afforded in this class of stoves, whilethe cost of manufacture of said burner shall be reduced, and to better unite the severalessential elements of the stove than has been done in previous constructions. To accomplish all of this the invention consists in several particular details of construction, and in certain new and useful arrangements or combinations of parts, as will be hereinafter rst fully described, and then pointed out in the claims.

The elevated oil-reservoir A, Figs. l and 3, is closed at top by two plates, C and D, separated by a little space. The upper plate D is preferably depressed in the center, as plainly shown, and the perforation therein is somewhat larger than the pipe B, which is intended as the main conductor of oil when filling. A

`narrow lring of wire netting or perforated metal, c, vunites thepipeB with the perforation in the top plate, and the inner plate Gis united with said pipe, which pipe is provided with a perforated cap, b. A hinged lid or other suitable cover, E, closes the opening in plate D, and a small perforation, a, intended to be left open, is placed inthe lower plate.`

In filling the reservoir the oil is poured in through pipe B, which, when the reservoir is sufficiently full, ascends in said pipe and flows over its top, thus plainly indicating to the operator the amount of oil .in the tank. The

Vportion which flows over pipe B nds its way immediately down through gauze c, and nally through perforation a. This arrangement renders the danger of, overlling directly attributable to the carelessness of the operator,

and if by any extraordinary accident a too great quantity of oil be discharged from the filling-can after pipe B is full to its top, the overcharge simply flows into the space between the two plates G and D, where, when the cover E is closed, (or even if it be left open,) there is little or no danger of its taking fire. The inclined top compels all the drip from the iilling-can to flow down into the reser Voir, to facilitate which it is preferable to allow the lidE to iit down upon its seat rather loosely. The operation of the wire-gauze or perforated material to prevent communication of iiame therethrough is well known, and need not here be detailed. All communications with the interior of the reservoir being thus protected, it will be practically impossible for the contents of the said reservoir to take re.

These details of arrangement are specially advantageous in this class of stoves wherein the lighter forms of hydrocarbons are ernployed, rendering liability tol 4accident extremely improbable. It is by no means intended to be herein admitted that the real danger from use of these light oils is anything like so great as the uninitiated imagine; but the safety attachments are noue the less valuable, for, in the hands of an inexperienced operator, the premature combustion of the oil is really only dangerousv because of loss of presence of mind by the operator, in Aconseu quenceof which he might/be incapable of extinguishing the names-a -matter very easily accomplished.

. VIn order to catch and hold the oil which may drip from the burners of thel stove or from any one of their connections, I place a reservoir beneath the row of burners, (or in the event that only oneburner be used, then beneath it,) and arran ge suitable conduits leading thereto. In the form chosen to illustrate this portion of the invention, which form is shown in Fig. 1, the arrangement is as follows: N is the sub-reservoir, suspended from the ordinary shelf beneath the burners by means of the funnels f f f, the outer rims of which bear upon the perimeters of suitable perforations in said shelf, the lower ends of the funnels uniting with pipes g g g' extending nearly to the bottom of said reservoir. One of the funnels being located under each burner,`they will serve to collect the drip ,and cause it to be discharged as required. The pipes y g g are made to extend nearly the depth of the reservoir, so that their lower mouths will be covered by the oil as soon as any quantity collects, and thus prevent the escape of carbureted air up 4throughthe funnels, which escape might otherwise occur, and from which only is any real danger to be apprehended. The top of the sub-reservoir is provided with a pin-hole, as at h, to allow escape for air as the oil enters 5 and any suitable plug, i, at or near the bottom, aords a convenient means of emptying said reservoir of its contents. The sub-reservoir is preferably made of sufficient capacity to hold as much oil as does the supply-reservoir A, in order that, if any accident should occur whereby all the material should run out of the latter, it will be safely stored in the former.

Under the arrangement shown, should any of the drip take fire while in the funnel or in its vicinity, the pipe g. prevents communication of flame withV the interior of reservoir N. In addition to the utility of this reservoir N in preventing any accident on account of the drip from the burners, it serves as a means of keeping the lower shelf in a more cleanly condition than heretofore, and also prevents, in a considerable manner, the odor from the dripping oil. Further, if the leakage be considerable, and the oil should take lire while finding its way to the sub-reservoir, the flame would be extinguished at the mouth of pipe g; or, in other words, the pipe g prevents admision of flame to the reservoir, as abovekintimated. y s i 'llt will be observed that the supply-pipe, to which the burners are coupled, is suspended beneath the top plate, and located practically in the axis of the stove. The sub-reservoir occupies a position beneath this pipe, and its conduits are so arranged as to catch the drip from the couplings between the supply and burners, as well as from portions of the burners. a i i i It is found desirable to unite a water-tank with the gasoline-stove in such a manner that it shall not interfere with the use of either .one of the burners for the ordinary purposes lof cooking, and so as to fulllnumerous other conditions, as will hereinafter appear. i

`The water-tank P is connected with the two pipes K K', which are made to form the coil surrounding the burner, as plainly shown in Figs. 1 and 4., and which extend out sufficiently from the portion of the stove immediately over the burner to support the tank in a.l position also removed from said burner.

`Water from the tank passes down through pipe K, thence through the coil, and up through K, completing the circuit, as in all similar water-heaters. The circulationV is controlled by means ofthe valve d, (shown enlarged at Fig. 2,) and water may be conveniently withf drawn from the tank by means of a cock, e, connected with pipe K. a

There being no pressure within the tank P, as in ordinary range-boilers, it becomes important to prevent the water from being forced out of pipe K with too great violence, as would occur when the burner is lighted if no special provision be made for such prevention. a

As at Fig. 6, a cork or other valve, o, is seated over the mouth of pipe K, and secured in place by a perforated cap, n. While the circulation is downward through pipe K the valve crests upon its seat, and permits the flow ofwater through its notched sides without interruption. As. soon as too great back-pressure is created the valve rises, closes the opening in cap n, andV thus forms an effectual barrier to the re- Yverse iow of water. a a a r It is preferred to make a the valve of less equivalent, Iam enabled to overcome the ob jections to the use of the side tank, with cirplained.

'codecs 3 specific gravity thanwater, in order that it willbemore sensitive to the action thereof; but it could be otherwise made and still fall within thelimits of the invention.

By providing this check or. its mechanicalculating-pipes, .and to adapt it for the uses exf The tank as lforms the base upon which the vsteamiIig-chamber R issustained. In this chamber the ordinary operations 0f steam cooking may be performed, the cham` Vber being provided with suitable supports for cooking utensils m m. The top of the tank is provided ,with a depressed cover having a Ycentral perforation, and may thereby be conveniently iilled without removing the steamer by Simply @peiling the'dwf and poringihe wa. Vter in upon the aforesaid cover.

j When tnot required for use, thesteam'er may. be removed andthe opening in the top of the tank covered by any suitable cap'.v g

The convenience and futility of both the tank and the steamer, when arranged as aboveV described, are suficientlyobvious to require no particular mention.- TheI arrangement `is specially advantageous over thatfform of tank `and.ysteam-chamber designed lto bejlplaced direotly over the burner, in many respects, but

especially inithis, that in the latter class the I y tom, and permit a free circulation of air around water ,isy liable to be completely evaporated, and the food spoiled (in, consequence, whichA is not likely to occur under the use of the coil, inasmuch ras a timely warning pf a low1 state ofwater' inthe tank is given the operator by the rattling noise of lthepipes and tank produced by the circulation of steam and a small quantity of the water. The depressed cover operates to. return all th'efcondense-w'ater from the steaming-,chamber back into thewatertank.

Tolsupport the tank` in fa substantial Inanner, it is desirable to connect it'kwith the top plate of the stove, and to'acco'mplisli this'I unite the pipe K rmly with the bottom of the tank, and screw its lower end into a socket cut in the 'top plate. Beneath this socketis a similar receptacle for thatfend of the c'irc'u#` lating-pipey which ,is below the top plate, land when the, two portions ,are 'properly located, no interruption in the circulation' can occur. The portion K of the circulating-pipe isunited with the tank at or near the center of the bottom, and the two connections thus made renderthe support for the tank as rigid as is desirable or practicable. i v l As the most convenient means of sustaining the end of, the oil-,supply pipe G,`I 'adopt vthe following; I extend said pipe outptowardthe l tank endoffthe stove, and connect its extremity, with they coupling M, (which may be a pipe or a solid 'rod,) tothe shell'ofk the` circulation c'o'cko'r valve d. This answers all the essenl tial requisites of fa goodunion lbetween the supply-tube and the top' plate; but, to avoid any possibility of the escape of oil into the should be formed so s to oppose the desired barrier, as plainly shown at Fig. 2.

In order to couple the top plate', the legs, the shelf, and the supply-tube in a iirm Vand substantial mann er, and thus renderthe Whole structure little liablertobe unduly shaken and rackechthe legs O O are turned with an annular projection, which falls just above 'the shelf, and the coupling rods or pipes I I,A united with the supply-pipe, are made to draw 'the shelf up against the projections 'upon the legs by means' of thumb-nutsor'other suitable attachments below the shelf, as illustrated in Fig. el." The supply-.pipe being connected with the top plate atea'ch end, the union-pieces I ,I serve'as a very effectual means of stiii'ening and bracing all` parts of thelstove. The guards HH surround the burners and depend from the stove-top, to which they are attached. They extend down sufficiently to prevent 'any side draftsof air from\ interfering with the proper working of the llame, and they alsoser've to better direct -the heat fromtheburner upwardly up'on the utensils placed upon the stove.

,'Jlh'eshields orwind-guards are open at botth'e standpipe of the burner, which is located atright angles to the supply-pipe, while they f (the shields) leave all4 the valves and' attach- Vments in such position as to be readily accessible for lighting and operating the stove, and

I so that'they maybe readily inspected at any time without disturbingthe said shields. l

. The shields, are, moreover, attached to -and depend from Ithe removable sections of the top plate which are over the burners, so that, in the event that it be necessary to remove the` burners or to reach them for other purposes, they are easily accessible by simply lifting out the sections of stove-top which carry `the shieldsl with them, and thus expose the vburner at top and sides. l The cover shown at H2 is vintended tobe placed overiiat-irons and other articles' to better'coniine the heat over their tops. This is found towork admirably for the purposes `intended, especially when employed in connectin with the guard H, with which it forms a comparatively closed chamber, and affords lstrikingly beneficial results.

The burner, shown enlarged at Fig. 7'-that is, enlarged beyond other views of the stove partsbut not beyond its actual sizef'fis constructed toil afford a largely-increased* area `of flame over previouslylexisting forms, and with a view'to simplifying its manufacture andre- ,ducing thecost thereof.-

The 'cone portion of the burner has heretofore 'been cast separate from the oil-supply channel, and thebody of the burner has been so formed as to require considerable drilling and fitting to open the requisite passagesfor the oil. To obviate all this I cast the top or cone T together with the inlet-tube V for mingled air and gas, and with the socket U adapted to receive the end of the oil-chamber The channels V and U are made cylindrical, by means of which the operation of casting is simplified, as is readily understood. This form of top for the burner makes the support for the cone independent of any pressure which may be created in the vaporizingchamber p, and therefore not liable to be blown 0E and the union between the cone and vaporizingchamber is of such a character as that heat is conducted much better from the former to the latter. To secure the proper location of tube V over the jet-orifice when the cap `is placed in position, the socket U has a notch cut in its wall at the lower portion, and this notch engages with a corresponding lug upon the side of the vaporizing-chamber. rlhe general form of the vaporizing-chamber is cylindrical, by reason of which it may be easily fitted to enter the socket U by turning it off in an ordinary lathe.

The elbow which sustains the needle-valve g, and in which the jet-orifice is located, is'cast with the vaporizing-chamber, the horizontalchannel in said elbow being connected with said chamber by a properly-located core during the process of casting.A This obviates the necessity of drilling such horizontal channel from the outside of the elbow, andafterward plugging up the initial perforation, as has heretofore been done; and this method of forming this section of the burn er is preferable to the old methods for many obvious reasons; but it is intended to adopt the old method should occasion require or seein to warrant, the other general construction being adhered to.

The adaptability of this union between the vaporizing-chamber and the cone to conduct heat from the latter to the former renders it practicable to increase the size of the cone considerably beyond former styles, and at the same time dispense with the ordinary heaterplate and the auxiliary jets necessary to convey heat to the same. The increased size of the burner ,a'ords an extended flame area, and

gives good results over and above former conl structions, with practically the same consumption of fuel.

The burner is operated as are all burners of this class, and the gasoline-stove has now become so well known as to require no explanation of the operation and uses of its different pose to make separate application for Letters Patent.

In acknowledgement of the state of the art to which this invention relates,`I will state that I am well aware of all the patents heretofore issued thereunder, and that I am acquainted with the various styles of stoves placed in practical public use.

I do not, therefore, desire it'understood that I lay any claim herein to the metallic top plate supporting a row of burners, to the shelf 1ocated under' the burners', nor to a burner for gasoline wherein a cone is simply placed over a needle-valve which controls the flow of gas.

I desire also to acknowledge that a dripcup has heretofore been located beneath a row of gasoline-burners, and intended to catch thedrip therefrom.

According to this previous construction the drip-cup is suspended beneath an inclined funnel-shapedshelf, which conveys the drip from the valves of the burners, but not from theircouplings with the supply-pipe; and the cup has'not been madeof suflicient capacity to hold all the oil which might iiow from the oil-reservoir in case any one of the valves should be left open. To the mere cup, as thus formed, I lay no claim; but,

Having thus fully described my invention, what I do claim as new, and desire to secure by Letters Patent, is-
