Description
UNITED STATES PATENT OFFICE.
ALEXANDER MCPHERSON, OF NEYV YORK, N. Y.
COOKING-RANGE.
Specification of Letters Patent N0. 9,674, dated April 19, 1853.
To all whom t may concern:
Be it known that I, ALEXANDER MoPHnnsoN, of the city, county, and State of New York, have invented a. new and useful lmprovement in the Construction of Ranges,
Stoves, &c.; and I do hereby declare the following to be a full description of the same.
The nature of my invention consists in combining the construction of the grate with the mode of carrying the flues do-wn the ends of the range andunder the oven. But'to describe my invention more particularly I will refer to the accompanying drawings, forming a part of this schedule, the same letters whenever they occur referring to the same parts.
Figure l, is a perspective View of the range, having one of the oven doors open and bottom plate of the oven removed to show the iues. Fig. 2, is a plan View of the range having the top plate removed. Fig. 3 is a cut sectional view of the range through the lines x, Fig. 2, except showing the entire front of the grate. Fig. l is a cut sectional view of the range through the lines i122 m2 of Fig. 8, showing the arrangement of the side and back flues and mode of causing the gas to cross over the bottom of the oven by means of the oblique cross plate. Fig. 5, is a cut sectional view of the door and grate through the line m3 003, Fig. 2, to show by the arrows the passage of the air to the furnace.
Letters A, A, are the external plates of the range.
B, is the top or boiler plate, having at C, C, two pipe holes for the escape gas.
D, is the grate, made in the form of the two sides of a right angle, and having at E, E, two supports or ear pieces to sustain the grate upon the flanges F, F, forming the inner wall of the furnace. This grate has a broad bridge piece G on its front and upper end, the top edge of which has a flange H, bent over and outward, so as to rest against the inner side of the door, and thereby have a space of some two inches, more or less, for a radiating space between the bridge piece and the door. On this bridge piece are a series of ribs z', 2', &c. These ribs are vertical and are placed so as Ato form grooves or channels about two inches in diameter, more or less, and about two inches apart, more or less, for the purpose of forming channel ways for the passage of air when the grate door is shut. In the flange H, are a series of holes, J, J, &c., through which the air from v the channels passes to the furnace.
Letter K, is the furnace door. This door has a flange L, on its inner side correspond?. ing in depth with the iange H, on the bridge piece of the grate,I so as to form when the door is closed a chamber against the bridge piece, between the two flanges H and L and the door and bridge piece. Through the door are perforated a series of air holes M, M, &c. These holes (see Figs. l and 5) are intended to admit currents of air through, which being prevented from passing down between the bars of the grate to the furnace, by the flange L, on the inner side of the door, causes it to pass up between the ribs against the bridge piece and out at the holes J, J, &c., in the upper edge of it to combine with the escaping gas in a heated state and thereby cause a more perfect combustion of the gases.
Letters N, N, &c., are two flues at each end of the range, and forming the end sides cf the oven. These flues open at the thin lower ends underneath the bed plate of the oven (not exhibited, drawings for the purpose showing the flue under the oven) and discharge the gas in the direct-ion of the arrows Fig. 4) in the compartmentP,made by running a plate R, diaognally from the back to the front across the chamber under the bed plate of the oven. This plate R, has an opening in it at R2, through which the gas passes following the direction of the arrows, into the compartment P2, to escape at the back liuc S, at the back of the oven and thence to the pipe holes, C, C, to the chimney.
Letters T, T, are two dampers running in over the ovens and shutting against shoulderV pieces V, V, &c., to prevent the direct communication with the pipe holes C, C, and to cause thereby the to pass under the oven before escaping to the pipe holes.
The operation of these improvements are that when a iire is commenced in the grate the dampers are opened directly with the pipe holes C, C, so as to get up a quick fire. As soon as this is obtained, the dampers are shut to cause the gas to take the circuitous route of the end flues and under the oven, and so up the back flue before it reaches the pipes C, C. In consequence of this lateral and downward action of the draft, the action of combustion is impeded, and as a natural consequence there is a large rio quantity of unconsumed gas escaping and producing no beneficial eEect in the ovens, though the quantity of coal used has been abundant. As the bridge piece of the grate has noW become heated (by the time the dampers are changed) the air passing in through the holes of the grate door and in contact With the bridge piece becomes heated, and escaping in that state through the holes in the upper part of the bridge piece to the furnace unites with the escaping unconsumed gas, which with the additional heat and oxygen supplied to it causes a perfect combustion, and thereby the use of less coal to produce a better cooking and bak ing range than has been previously made.
