SAMEL J. MCDOVELL, OF BOSTON, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO VVILLARD O. ARMES, OF SAME PLACE.
PORTABLE COOKING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 428,569, dated May 20, 1890.
.T all whom t zii/ay concern:
Be it known that I, SAMUEL J. MCDOWELL, of Boston, county of Suffolk, and State of Massachusetts, have invented an Improvement in Portable Oooking Apparatus, ot which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
1o In another application, Serial No. 238,104, filed May 13, 1887, Ihave shown and described a portable cooking apparatus comprising a roasting-oven, a steaming section or boiler, and a casing containing two ovens provided with a flue arranged in said oven, so that the products ot' combustion will pass around them on the way to the chimney.
This present invention relates to the construction of the casing containing the said 2o ovens, it being herein shown as connected to a iire chamber or stove.
The particular features in which my invention consists will be pointed out in the claims at the end of this specification.
Figure 1 shows a vertical section of a cooking apparatus embodying my invention, and Fig. 2 a detail to be referred to.
The stove A may be of any desired construction, it being shown as divided by the 3o grate a to form anash-pit a below and a tire space or chamber c2 above the said grate, the said ash-pit and tire-space having suitable doors a3 d4, respectively.
The top of the stove is shown as made in 3 5 two sections b b', of hre-brick, soapstone, or other refractory material, the said sections being shown as halved in or rabbeted and supported by the ends and sides of the stove, thesection b having an opening for the 4o kettlcs and pots, the said opening being herein shown as closed by a cover b, itted in removable rings o7, the said rings permitting kettles of various sizes to be placed in the opening over the re space or chamber a2.
The stove Alias extended from it a section B, which forms with the section b a iiue or passage B,the section B being made, as shown, of two metal sheets or plates c c', and an intervening layer c2, of asbestus or other nonheat-conducting material, to prevent the radiation of heat from the lower side of the flue or passage B. The section ZJ is shown as provided with an opening'c3, constituting an outlet for the passage or flue B', the said section having a collar c4 around said opening 55 and extended up into a casing D, herein shown as partially supported by the leg (ZX, the collar c4 being shown integral with the section b. The sides and bottom of the casing D are made of two plates or sections CZ CZ', and pref- 6o erably two or more layers or sheets cl2 of asbestus or other non-heat-coi'iducting material, and an intervening sheet or plate cl3 of metal, the plates or sections CZ d being preferably corrugated, as shown in Fig. 2, the corrugations extended or lying substantially at right angles to one another, and forming chambers d5 between them and the layers or sheets ot' asbestus, as clearly shown in Fig. 2, the sheets of asbestus being indicated by the full black 7o lines in Fig. 1. In Fig. 1 the plate CZ only is corrugated. The sides of the casing support a top plate c, provided with an opening encircled by a iiange c', to which may be fitted the chimney-pipe c2, (shown as integral with the flange e',) the said chimney having a slidedamper eX. Secured to the sidesor otherwise supported above the bottom of the casing, is
a plate e4, forming a passage c7 below it, the said plate having an opening from which, as 8o herein shown, is extended upward a flan ge c6. The ilange e is embraced by the lower end ot a vertical section es, joined by a horizontal section el@ to a'vertical section c of a pipe or flue D', the section c being atthe opposite 85 side of the casing to the section es, the said pipe or iiue dividing the casing into two baking-ovens g g. The section e9 embraces at its upper end a ilange c5 of a plate c3, secured to the sides ot the casing, the said plate forming 9c with the top plate e a passage cl2, connecting the section c with the chimney c2. The bottom and left side of the oven g is provided with plates g2, between which and the plate and pipe section es is interposed a layer g4 of 95 asbestus or other non-heat conductor. The bottom and right side of the oven gis also provided with plates g2 and layer q4 of asbestus. The bottom and left side of t-he oven g and the bottom and right side of the oven g 10o are more exposed to the direct action of the products of combustion passing through the flue D than the upper sides of the said ovens, and ordinarily the said ovens would be unequally heated, it being hotter at the bottom than at the top of the said ovens.
The double thickness of plate and the layer of asbestus between serve to dampen or reduce the heat at the bottom part of the ovens, thus producing a substantially even temperature or uniform heat'thro u ghoutthe said ovens.
The products of combustion from the iirespaee a2 pass through the flue I3', passage e7, and flue D inte the passage em, from whence they pass into the ehim ney, the draft of the said chimney being controlled by the damper ex.
I have herein shown the casin gD as divided into two ovens; but it is evident that the said casing may be enlarged and the pipe-sections extended to form three or more ovens.
Each even is provided, as shown, with a grating c and door em.
I have herein shown the outlet e as located atI one side of the casing D and communicating therewith through the bottom; but it is evident that the said outlet may be connected through either side et the casing er near the center of the bottom of the said easing.
l. In a` cooking orheating apparatus, a easing D, composed of two corrugated sheets or plates l d', and an intervening layer of nonheat-conducting material, the eorrugatious of one sheet er plate extending substantially at a right angle to the corrugations et the other, substantially as described.
2. In a cooking or heating apparatus, a easing D, composed of two corrugated sheets or plates (l d', two intervening layers of asbestus, and a sheet or plate between the layers of asbestuathe corrugations of one sheet or plate extending substantially at a right angle te the eorrugations of the other, substantially as de' scribed.
3. The combination, in a cooking apparatus, of a casing D, composed of two corrugated sheets or plates (Z d', the corrugations being at right angles te cach other, and an intervenin glayer of non-heateonduetin g material, with a stove A, having an extension B, coinposefl of sheets or plates c e', and an intervening layer c2 of non-heat-conducting material, and a nen-conducting top b', provided with an opening and surrounding collar, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
