FRANKLIN COOKING-STOVE.

Specification of Letters Patent No. 1,427, dated December 12, 1839.

To all whom it may concern Be it known that I, ABNER R. RING, of Parma, Monroe county, State of New York, have invented a new and useful Improvement in Franklin Cooking-Stoves, which is described as follows, reference being had to the annexed drawings of the same, making part of this specification.

The nature of this improvement consists in a certain new and useful combination of a swinging damper in the back plate of a common Franklin stove with two sliding register plates or valves arranged and operating in such a manner that the draft from said common Franklin fire place is carried down under a rectangular oven placed behind andconnected with the franklin, having a boiler chamber over said oven and in constructing the back plate of the boiler chamber with apertures in it, so as to admit of the draft passing under the boilers after it has circulated under the oven and escaping in front through apertures in the front plate of the oven and boiler space governed by the outer and inner registers into the main flue or smoke pipe above the franklin; and also in so governing the register plates as to shut off the draft through the front plate of the oven, close the swinging damper against the back plate of the franklin, and a fire being kindled in the boiler space cause the draft to pass through the apertures in the back plate of the oven and boiler space into the flue behind it, thence under the oven and up in front through the flue formed by the back plate of the .franklin and the front plate of the oven and boiler chamber into the main flue or pipe above the franklin.

To enable any person skilled in the art to which this invention appertains to construct and use the same, I now proceed to describe its construction and operation more particularly.

Figure 1 is a perspective view of the Franklin cooking stove; Fig. 2, sectional view at the line a: 00 of Fig. 1; Fig. 3, inner sliding register; Fig. 4., outer ditto; Fig. 5, swinging damper in the back of the franklin; Fig. 6, perforated plate against which the inner sliding register moves; Fig. 7, damper in the main flue; Fig. 8, perspective view of the dampers in a position to cause the draft to pass under the boilers nearest the fire; Fig. 9, perspective view of the dampers in a position to cause the draft to pass around the oven; Fig. 10, back plate with apertures.

against which the inner sliding register Gr,

moves on one side and the main damper'H swings on the other side; K, back plate of oven and boiler apartment with apertures Y in it for the draft to pass through to the boiler apartment or from the latter around the oven; L, doors of the boiler apartment and chamber of combustion; M, door of the oven; N, door of the soot hole; O, han

dles of the dampers and registers; P, a damper 1n the main flue; Q Q, boilers nearest the fire place; S S, sides of the Franklinstove; A T, bottom of ditto.

The Franklin stove A is made like other stoves muse, except that it has a rectangular opening in the back plate for the draft to I be turned through said aperture when re-' quired, closed by a swinging damper H when the draft is required to be passed upward in the usual manner. and also an other back plate I placed parallel with'the' one just described and at a short distance in the rear of the same, so as to form a flue E for the draft when turned from the.

Franklin stove to the boilers Q or oven D, or from the boiler apartment 0 when converted into. a chamber of combustion, and

also in extending the bottom plate A T-of the Franklin stove to the rear a sufficient distance to erect thereon a cooking apparatus, consisting of a rectangular oven D for baking and a boiler apartment C above, into which are inserted several boilers Q, F for culinary operations, and which apartment may be converted into a chamberof combustion, said boiler chamber having a door on one side with holes on the opposite side to admit a draft when used for a fire chamber, which will bring the fire immediately under the boilers and over the oven, said apartment being furnished with adoor L at the side for the introduction of fuel.

The top plate of this apartment is also the top plate of the cooking part of the stove and contains the apertures for the boilers. It is joined to and forms a right angle with the upper back plate 2 of the franklin; The

back and side plates of thecooking appa- ,ratus and the top plate of the oven, which is also the bottom plate of the boiler apartment; and the bottom of the oven are made in the usualmanner. the oven and boiler apartment is made rectangular and is cast with alternate rectangular apertures oand projections, p, on its upper edge, the apertures being for theipassage of the draft as hereafter described, and said plate is curved near the center, at which place there are cleats X forming channels for the registers to slide in. i' The inner register G, which is made hook shaped at its upper; edge for hookingbover and sliding on the upper edgeof plate I, moves against plate I, while the outer register G, which ,is half the width, of the inner one, slides against the latter'an'd between it and the cleats. The inner register G, Flg. 3,c1s a rectangular pieceof metal of suitable length,

breadth and thickness, containing a number of rectangular openings R and solid parts T between said openings, which are brought to coincide with the'apertures U in plate I Y for partly closing and entirely opening the,

when required to close them and is furnished with a handle 0 formoving it to the right or left. 7 The outer sliding register G, Fig. 4:, is the same length as the inner one, but only half' its width,'and is cutout on itslupper edge, so as to form alternate rectangular depressions {v andprogections W apertures in the inner register, against which it slides beckward and forward, having a'handle O' for moving it." The. back plate K of the oven,rwhich is placed-a short distance in front of the back plate of the. cooking part of the stove, is continued'from 'the bottom of the oven to the under side of the 'top plate of the stove, having apertures Yin it along'its upper margin for thepassage of the draft from thefranklin A under the: oven to the boiler apartment C and from theboilerapartment (when converted into a chamber of combustion) around the oven D to the main flue B. a

The swinging damper'H is a rectangular piece of metal of greater width than the opening in the back plate of the franklin in order to 'lap over its'edges when the aper ture is to be closed and tojreach thecen'ter of the inner register when it is to be opened; Itjis suspended on a horizontal rod 0 0 passing through the sides 18 of the franklin and is turned by a handle 0. The'damp'er P for dividing the main flue B into two parts- I and changing the draft into either at pleas tire is also'suspended on a horizontal rod 0 v passing through'the ends of'the flue'an'd turned to the right or'left by a handle 0.

The legs, boilers, and "ornaments of the stove are-made in the usual manner.

Operation: When the fire is'lmade'inlthe The front plate I of .Witnesses:

franklin 'A and the draft is to be turned under the boilers F and Q the dampers and registers must be placed in the position represented in Figs. 2 and 8namely, all the apertures coincident, and the damper 'H turned, its upper edge being against plate I and the damper P turnedso as to open the rear part of flue B and closethe frontpart. When the draft is required to be turned around the oven D-anduncler the boilers the registers and dampers must be'placed in the position representedin Fig. 9 namely, as

described above excepting the outer register G, whichimust be moved in so as to bring its projections W" over the lower parts of the apertures R, which willcut off thedraft through these apertures and turn it down under, up and over the oven and through the upper parts of the apertures R to the main flue B. The position of the dampers and registers will'be the same as that just described when fire ismade in the boiler apartment to be used under the boilers alone; but whenitis required to-cause the draftfrom the boiler apartment'to circulate around the oven,then'the inner register Gr must be moved so-as to close the apertures U in plate I entirely, which will force the draft to pass along the flue E to the 'main line B.

Having; now described the construction and operation of the improved 'Franklin cooking stove, I will-proceed to state what 'I claim" as my invention and desire to secure by Letters Patent, which"is- The combination of-the damper H-in the back plate J of the franklin with the" registerplates or valves G G." arranged and operating as described,by means of'whic'h the draft is carried down-under the oven D and in connection therewith the constructing the back plate K of the boiler chamber C with apertures so as to admit of the draft passing under the boilersafter it has circulated under theoven and escaping in front through the apertures U governedby the outerregister Giinto the main flue or double pipe .13 allias described; also'the combination of the apertures Y in theback plate K oftheboiler chamber C with the valves or registers'G G" by'means of which arrangement the inner register G being closed the boiler. chamber '0 may be employed as a chamber of combustion, "the draft passing through the aforesaid aperturesY into the back flue E, thence under the oven and up in frontthrough the flue E formed by the backplate J 'ofthe franklin and-"the front plate I- of'the oven andjboiler chamber, into the main flue orpipe B the whole being con structed and operating asdescribedi ABNER RPRING. 3
