IMPROVEMENT IN vAeoa-slTovEs.

Specification forming part of Letters Patent No. 42,103., dated March 29, 1564.

To all whom z't-may concern:

Be it known that I, OSCAR F.- MonnILL, a resident of Chelsea, in the couuty'of Suffolk and State of Massachusetts, have made an invention of certain new and useful Improvements inApparatusfor Generating Heat for Culinary or Various other Purposes; and I do and a suitable number of legs, b b, extending,

therefrom.- Withinpthis stand there is arranged an aerovapor burner, B, which consists of atube, c, which is open at its lower end, and at its upper end is capped by a foraminous plate or wire-gauze diaphragm, d, over which there is a perforated chimney, e, which extends through the part a concentricall y and rises above it, as shown in Fig. 2. Raised Sonne distance above this stand there isa reservoir or close chamber or vessel, C, for holdvin g petroleum naphtha, or carbon spirits, or any liquid easilyvaporizable and combustible,.the said vessel C being supported by'a conduit or tube, D, which not only passes'entirely through and extends a short distance above the said vessel, but also extends downward from it toward the stand A and through4 a block of wood, E, (or some other suit-able noaconductor ot"hcat,) held in place by means of an arm or projection, F, fastened to and extended from the said stand'. The purpose of the block E, which I term-the insu'lator, is to so insulatethe conduit from the stand-asl to prevent the heat ofthe latter, when the' apparatus may be in use, from being so absorbed by the conduit as to vaporize the liquid which may be flowing down the vertical part of it. A From the said insulator the conduit extends horizontally underneath the tablet c and over the foraminous diaphragm of the burner, and thence down alongside of the exleerior surface of the said burner, and thence.

isca-rried horizontally into the .lower part of the burner and opens into a vertical jet tube or receiver, Gr. At its upper end thesaid receiver has a very sinall ednctionoritice,

which is conical, to receive a conical valve, y, whose stem is furnished with an elevatingscrew, h, and a pronged wheel, t', arranged as shown in Fig. 2. The said screw is tapped in to'the receiver" G, and when turned in one direction will elevate the valve toward its seat or the opening f. The screw, when revolved in the opposite direction, will depress the valve. At the bend k of the couduitD there is another such valve and valve-seat, the same being shown at Z and m in Fig. 2v, the stem n of the valve being extended up through vand out of the standard or longer verticalpart of the conduit, as shown in the drawings. Such stem, atits upper end, is provided with a hand-wheel, o, by which it may be revolved. The hub of the hand-wh`eel is recessed to lit around and screw upon the upper part of 'and constitute a cap to the conduit, as shown at p in Fig. 2.' Furthermore, the reservoir C is furnished with a llingorice, q, provided with a screw cap, r, andthere are two holes, s t, made through that part of the conduit D which is withiny the reservoir C,

one of-these holes, s, being near the top, and the other, t, being near the bottom, of the reservoir. Surrounding the chimney is a sepa rate casing, I, having lnumerous holes, `'u ul u, made throughits sides. 'It is through these 'hoies that the spent volatile products or gases make their escape 'after having actedV on the vessels or apparatus which may be arranged over the chimney. The casi-ng I has a contracted-neck,'v, made to receive another casf ing or. boiler-supporter, K, which rests upon it, and is rformed as shown in the drawiiyigs.

vrlhe said'boilerlsul'iporter K isprovided with',

one or more rings, zc, and a-ciicnla'r cover'or plate, The second ring laps on the iirst ring, and in its turn is lapped' on bythe third ring, lwhich is also lapped on by thel'cover, the whole being arranged concentrically and formed as showiiiu the drawings, and particularly in Fig. 3. W'lieli the rings and cover are in place, they serve to cover the opening in the top of the'boiler-supporter,and may 'be used for sustaining one or more sad-irons or other articles or vessels to be heated by the flame of the burner. By' removing the cover from the inner ring, we shall have an opening either for insertion of a kettle, boiler, or 'pan' into the lat-ter, or for the adinission'of neat directly to a pan or vessel when placed on the said ring. So,by removing the second, or second and third, rings from the rest of the apparatus, larger openings may be formed forvalve is also employed to regulate the dis-v charge of vapor therefrom, theheght of the `dame may be adjusted and the apparatus will A operate to much better advantage than with l but one valve.

Furthermore, by having the conduit, extended into, through, and out ot' the reservoir in manner as specified, and pro viding the conduit with the ex'tra hole, s,ar

ranged nearthe top of the reservoir, any fluidwithin the conduit willA not be liable to be expelled from or driven out of the top of the cmduit; but when back iiowage, occasioned by theV pressure of the gas or vapor in the vaporizer, may ta'ke place, such fluid will be driven through the hole s and back into the reservoir. i Y

The arrangement of the lvalve rod or stem n within the conduit v1) in manner as shown in Fig. 2.11ct only imparts strengthto the conduit, but enables the Ihand-wheel to'answer the twofold'purpose of a cap to the conduit and a means of rotating the valve-stem.l Byhaving thc reservoir Celeva-ted above the burner or iixed on a conduit rising some dis-- tance above the stand,I am enabled to obtain a head or pressure ot' the iiuid in the conduity 'advantageous to its emission through the mailtvalveopening and into the "aporizer, I would also remark that, instead of carrying the conduit straight over the burner, it may be curved more or dess, so as to increase the heating-surfacc ot' it. I would further state that, in consequence of the position of the hand-wheel and its valve-stem n there is not the' danger of leakage that there would be with a faucet-valve arranged atV the head vof the conduit.

I would also remark thatinstead of extending the conduit up into or through'the reser- Voir,4 I sometimes arrange theconduit so as not togo ythrough or up `into it, but to' open out of .its bottom, as shown in Fig. 4. This, however, does not present the'l advantage of the extension of the conduit from top to 'bot.

extension of the conduit through the reservoir. I 'would further remark that the manner of combining lthe hand-wheel o of the valve-stein n. with the conduit' B-that is to say, by re- 4cessing the'handfwhecl and screwing it on the top ot' the conduit-Ilot only provides a means of regulating the valve independently-of the reservoir, but causes the hub of the hand- Whecl to serve as a cap 4to the openingat the top ot' the reservoir or as a means of closing the same. I would further remark that it is often the case that while the valve may be open the formation and pressure of combustible vapor within the vaporizer or conduit may not be 'suticient to carry the effluent stream up through thew'ire-gauzeor foraminous top ofthe burner. It will therefore be seen that were there no valve at the oritice of discharge, it would sometimes happen that the stream of combustible vapor passing out of the conduit orvaporizer would not press upward with the force required to have it properly rush through the foraminous top' ot the burner, but with an adjustable valve the sizeV of the opening of discharge may be so regulated or diminished as to cause the vapor to ascend with theforce and to the height required. This will be so particularly when there may be but a small portion of the fluid iiowing into the vaporizer.

- Having thus described my said apparatus, what Lclaim therein as my invention is as follows, viz':

1. The' arrangement of the valve-stem, reservoir, conduit, and -handwheel when the conduit is extended into and through the reser voir. i

2. The extension of the said stem and conf duit lthrough and beyond the reservoir, and providing the conduit with the extra hole s,

vthe whole being substantially as specified;

3.. The combination ot the auxiliary valve g and -its actuating mechanism, (screw h and whee1z',) or their equivalent-s, with the aerovapor burner, as described, its conduit D, reservoir C, its main valve l, and an actuating mechanism, so made and-applied to the valve las to be so separate and distinct from the actuating mechanism of the auxiliary valve g as to enable either of such actuating mechanf' isms, with 'its valve, to be operated or putin operation without at the same time effecting any movements of' the other of the said actuating mechanisms and its valve, the whole being arrangedA substantially as described.

4. The combination of the' hand-wheelo of the valve-stein n with the conduit D, substantially in manner and so as to serve the purposes asspccitied, the hand-wheel under such circumstances being recessed and screwed on the conduit, instead of Vthe 4valve-rod bein g screwed. intothe reservoir.

t 5. In combination andarrangement with an aerovapor burner, substantially as described, and its luid-vaporizer, or means of converting the hydrocarbon fluid into a vapor, the adtiff;

(ivf

"justable valve g and its seat, .thes'ame being for the purposel of enabling the vapor to he 4ejected out of 4he vaporizer to a height suicealtnto enable it to pass up ,through the wire- -gauze diaphragm of they air and vapor mixer vaporizer and aerovapor hurner'u'ith auva'lve to regulate' the escape of vapor, under an arrangement to operate in the manner and for the purposes set fortl.

8. The combination of a fluid reservoir and vaporizer, the aerovapor burner, and the requisite valves to regulate the supply ofvuid and the escape of Vapor, together with a stove or support for Vessels `or articles' to be heated. OSCAR F. Motorini..
