GARDNER CHILSON, OF BOSTON, MASSACHUSETTS.

FURNACE-BAKER.

Specification of Letters Patent No. 1,627, dated J une 10, 1840.

To all whom t may concern.'

Be it known that I, GARDNER OHILsoN, of Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Bakers for Culinary and Such other Purposes to I/Vhich the Same May be Applicable.

These improvements, the principles thereof, and manner in which I have contemplated the application of said principles, by which the same may be distinguished from other invent-ions o-f a similar nature, together with such parts, improvements or combinations, I claim as my invention and rhold to be original and new I have herein set forth and described which description taken in connection with the accompanying drawings herein referred to composes my specification.

The object of my improvements is to accomplish at the same time, several other culinary opera-tions, with greater facility and expedition, besides that of baking (such as boiling, &c.,) without any greater expenditure of fuel than is commo-nly necessary in the use of such apparat-us. It will therefore be perceived that economy in the use of fuel and expedition in performing the several operations are the useful effects to be attained by my improvements.

The figures of the accompanying plate of drawings represent my improvements.

Figure 1. is a plan or top view of the baker. Fig. 2 is a vertical section taken longitudinally through the center, Fig. 3. being a horizontal section showing the parts in the interiors of the same.

A, A are the standards or legs which support the apparatus.

a b c (l, Figs. 2 and 3 is the tin baking apartment shaped as seen in the drawings,

lin the interior of which are fixed the wires or rods ma b b shown by dotted lines in Fig. 3, for the support of any pan or vessel 0 which may be placed thereon. The top, bottom, and sides of the baking apartment are arranged at such angles with each other as to reflect the heat powerfully to the article or articles in the pan or vessel at c.

A tin reflectingchamber a cl e f b Figs. 1 and 3, and CZ e f g 0, Fig. 2, of nearly a semi-cylindrical shape is placed in front of the baking apartment and attached to the same. Near the center of this chamber is the furnace 0 0 (Figs. 2 and 3) formed of a perpendicular hollow cylindroid the section of which is elliptical, of course, as shownrin Figs. 1 and 3. The elliptical lshape 1s preferred on account 0f its exposing a greater radiating surface in front and rear (with a less quantity of fuel) than can be possibly obtained in a common cylinder the circumference of whose section is equal to the perimeter of the ellipse. In the bottom of the furnace c o a suitable grating cl is fixed, through which the draft is derived; the ashes created from the fuel dropping through t-he same into a proper ash box e e Fig. 2 below.

The heat radiating from all points in the surface of the furnace is conveyed in part directly to the baking pan, the other portion being reflected to the same from the sides of the reflecting chamber and the top and bottom of the baking apartment.

An elongated hot air chamber E E Figs. l, 2 and l is attached to the top of the furnace c c and rests on the top of the reflecting vchambers a CZ e f b: This elongated chamber is divided into three apartments g L z"-7c. Z. m. a and 0l p g Fig. 1 by thepartitions 71. it L L la lo a a Fig. 2 (shown by dotted lines in Fig. 1.) communicating with each other by means of the openings or flues f g (Figs. lv and 2). Circular apertures F, G, I-I Fig. 1, are made in the top of the chamber E E opening into the apartments g it and lo Z and o p q in which apertures, the three boilers or other vessels lz, c' 7c Fig. 4 (in which the several culiniry operations are performed) are inserte It will readily be perceived from the ar-` concentrate the heat in the center apartment either of the flues )i g may be closed by'` the sliding valves o p operated by the rods g r Figs. l and 2, leaving o-ne open or partially so, in order that the hot air and smoke may pass to one of the discharge pipes. The two discharge pipes may be united in one common pipe which may communicate with an open fire place or the atmosphere to conduct the smoke, gas, &c., to the same.

tureof the central apartment,-covers being used on the apertureswhenthe boilers are .Y removed.. When the boiler over thev central aperture is removed a circular gridiron may be placed thereon, and the' process of broillA ing accomplished ,-in like manner' by re` moving thebaking pan ACV and insertinga spit &c that of roasting may be performed. In order that the exterior of the baker Aand other parts may berbetterl understood reference may beghadto Fig.` 4c Which'is a perspect-ive representation of the same. The elongated hot air chamber E `E may be constructed of sheet iron or other proper ma- I-Iaving thus described my improvements I'Ashall now proceed to specifically point out those parts which I consider newandclaim as my invention.

I claim- Y i a The combination of the elongated hot air chamber E E (divided into three apartments rg z/ hilf/mf who? p' g, by tvvo partitionsA K K-L L, Withfsliding valves A(o, p,"therein) 'with the elliptical or cylindrical furnace c 0, and also the combination ofthe latter `With the double reflecting baker surrounding the same, the Whole being'constructed and arranged substantially in the manner above set forth and described, -for the purpose of retaining andl circulating the heat throughout the apparatus and causing it to accomplishtheseveral operations i L i GARDNER oHILsoN.
