N nnirrEn sfraiEs PATENT oEEioE, j
ABEQGORNELL AND `NIRAM n.` MEEQIiANT, `on. GUILFQRD, NEW YORK.
y specification of Letters Patent No. 2,7124, ated July 1e, 1842.
To all whomz't may concern Be it known that we, ABEL CORNELL and j NIRAM R. MERQHANr, of Guilford, in the f county ,of Chenango and State of New York, have invented anew andlmproved Mode of i Combining the `@pen Franklin with the Elevated Oven Cooking-Stove; and we do herei by ideclare that the following is a full and exact description. 2 2
i 'The nature of ourinvention consists of an open Franklin and an elevated oven cooking 'sto've united-back to 2 back `and provided with a. car in which the lire is placed, said cartogether with the iire `is mo-ved into either part of the stove at pleasure.
To enable others skilled in the art to make and; use-ourl invention we will proceed to describe its construction and operation.
)We make the body of the stove `from (a) to (7)) Fig., 2, two feet and two inches, from (5) gte!l (c`) 2`,feet 2 inches, the height ofthe cooking part (c7, 5,) and ((7, c) is l0 inches. The height ot' the open Franklin (to, LU,) Figure ,1, is two i`e`et` The top of the cooking part oftlkie stove '2, projects 2 inches at (c7, (7,) overt-he end (e) which curves outward to receive it, and is level to just past the oven tlues` (g, where it forms a section of a curve of 4L inches radius upwards to the bead (r) whence it rises at an angle of about 25 degrees from a perpendicular to the top at (10,) and thus forming a part of the back of the open Franklin.` There are three boiler holes as shown at (7L, 7L., furnished with rings and covers. The opening through the rings are one side of the center as seen at Fig. et, `which by turninggthe ring allows the boiler `to be` moved more orless over the fire. The door opening into the fire chamber is seen at (m).
The hearth of the cooking part of the stove is shown at (70,) Fig. 2, its width (7), 70,) (c, 70,) 10 inches, its width (7), a, 7,) 5 inches and is carried on the same level to the back part of the-front of the open Franklin at (Z) and (r r) Fig. 1 and also as shown by the dotted line (a) Fig. 3. The middle of the hearth or bottom in the cooking part of the stove is sunk 2 inches in depth and 16 inches in width and carried out into t-he hearth (7c, 7c) the same width and depth and covered with a slide (s) by which the draft of air at (Q) to the fire can be regulated at pleasure. The middle of the hearth or bottom wit-hin the open Franklin is sunk linches lower and the same width (16 5 inches) making` 3?? inchesdeep to the level of` the hearth` (u) ang-1. i
The car in which the iireis placed is seen `at (x) and representedas drawn out-into `the open Franklin. t
(Ehe, partition between the cooking and open part of the stove is seenat-V This partition which is hung onipivots at its up.- per edge is called the swinging back, and is shownl morefully in section F ig.l 3, where (b) `showsits position andr (c) the postion of the lcar ,when in the open Franklin, and 4:thered dotted lines (e7) shows t-he position ot' the swinging back and (e) ,the position of the car when in thecooking part. A The swinging back is shown in ldetail at Fig. 7 where (a, a.) are the pivots and 5, 5) the ribs to keep Mtheplate from warping by the action of the lire andalso to allow a free circulation of" air between the back and the fuel. i The car is shown in` detail at Fig. 5. yThe widtlrfromfa) to `(79) `is 10 inches and from (a) to (G).is.,2feet l inch so as tomove fredlyfwithin .thestove The height 2; inches.
of the open stove sho-wn "The middle of the bottom is sunk 2 inches and grated.
When the car is in the open Franklin the grated bottom is 1.1; inches above the sunk hearth and allows a free draft of air up through the grates. lVhen the car is in the cooking part the grates fit close to the bottom of the sunk hearth. It then admits the air only at (g) Fig.z2 through a corresponding opening as seen at (d) Fig. 5.. The opposite side of the car (e) is solid for the purpose of forming a close partition between the two parts of the stove when the car is in the cooking part. The end of the car (a 5) is open and is directly against the door, (in) when in the last named position. The opposite end is nearly closed as seen at (j) Figs. l, 5 and 3.
The lower edge of the swinging back iskept from dragging in the fire in moving the car into the open Franklin by sliding` along the upper edge of the part (j) of the car, until it arrives at the curve (o) Fig. 3;
it then falls into the space as seen in the` Figs. 1, 3 and 5. lVhen the car ismoved from this latter position the curve (0) raises the swinging back and keeps it in this position until the car arrives in its place. V'Vhen in this position another fire may be kept in the open stove, at the same time the cooking is carried on in the other part of the stove.
i y y 2,724
The car can be us'edeither with or Without friction rollers.
The boiler hole (i), F igs. 2 and 3, is raised 2 inches and allows the smoke to pass over the swinging back into the open Franklin. This opening is closed at pleasure by the valve or damper (m), Fig. 3, which shows in section its shape and position when closed, and by dotted lines when open. It is hung on' pivots at its lower edge and extended upward nearly to the flue of the open Franklin (c). This is also accomplished in another way by carryino an oblong square flue obliquely through the inclined back and into the main flue at (p) as shown by the red lines on Fig. 8. vThe valve in this case would be shortened one-halt as seen by the dotted line across Fig. 6, Where it is drawn in detail.
There is a valve or damper by which the mouth of the Franklin flue may be closed to insure a stronger draft through the elevated oven. This valve is shown in section as closed at (s), Fig. 3, and open by the dotted line The elevated oven (p), Figs. l and 2, is made of two concentric cylinders of sheet iron, the inner one 13 inches in diameter, the outer one 16 inches, leaving a space 1% inches between the cylinders for the smoke and heat to pass through. This space is closed at each end by a ring of cast iron, and the loven provided with doors as seen at (t).
In order to prevent the escape of heat from the oven into the room in warm weather we inclose it in another cylinder of zinc or other polished metal, leaving a space of about half an inch between the zinc cylinder and oven, the cast iron rings at each end of the oven being extended suiiiciently wide to receive it. There are valves in the oven flues at (f, f,) which may be opened or closed at will. Vhen the oven is in use the smoke and heat rise in the lues (g, 9,), thence around the oven to (n) and escape at (0) in the Franklin pipe.
What we claim as our invention and desire to. secure by Letters Patent is l. The combination of the open Franklin with the elevated oven cooking stove by means of the movable grate or car and swinging back.
2. We also claim in combination With the above arrangement the valve or damper (m) for the purpose of regulating the heat of the oven.
3. We do not intend to limit ourselves to the eXact size, form or manner of constructing the respective parts aforesaid but to vary them as we may find expedient while they remain substantially the same as herein described.
