COKE- Be it'knownthat 1-, WILLIAM M. PERSON,

of Sparrows Point, in the county of Baltimore and in the State of Maryland, have invented a certain new and useful Improve- .nent in Coke-Ovens, and do hereby declare that the following is a full, clear, and exact description thereof, reference being had'to the accompanying drawing, in which the figure is a vertical section of a coke-oven, transversely of the regenerators, constructed in accordance with my invention.

My invention relates to coke ovens and the object of my invention is to secure the uniform heating of the ovens in all parts thereof, and to this end my inventioneonsists in the coke oven'constructed substantially as h ereinafter specified, and claimed.

The type of coke oven to which my invention relates is that shown in the United States Patent to Schniewind, No. 678,928, May 14, 190.1, which comprehends an arrangement of numerous vertical flues at the side of the oven through which the products of combustion from the burning gas pass upward at one end, and enter a horizontal fine, and thence across and down through the vertical flues at the other end-of the oven. All the vertical flues open into the horizontal flue mentioned, and I have discovered that, with such an arrangement of vertical and horizontal flues, uniform heating of the oven is impossible, for while the central portion is hot the ends are cold. The reason for this unequal heating of the oven is due to the fact that the suction or draft through the horizontal flue is ineifective on the flues at the end of the oven by reason of the fact that the up-velocity of the gas through the vertical flues at the central portion of the oven is so great as to blanket the end flues. To

' remedy this defect in coke ovens of the type in question, I subdivide the vertical flues into groups and connect a flue or flues at one end of the oven with a flue or lines at the other end by a horizontal flue, the arrangement being such that the flues at the same end of the oven can have no effect upon each other.

To illustrate an embodiment of my inven tion, I show in the drawing a coke oven comprising a series of receiving chambers or ovens as in Schniewind patent, the side walls of each oven being rovided with vertical 1 flues 11 which, at t eir lower ends are in communication with a combustion chamber 12, to which air for the combustion of the Specification of Letters Patent.

OVEN.

as is supplied from a regenerator 13, there being as usual, two regenerators, to enable the oven to be operated in the reverse direction, as usual. The combustion chamber 12 is sub-divided by vertical walls or partitions 14 into anumber of small compartments or chambers, from which 1e or more vertical flues 11 lead, and the upber ends of a group of vertical flues-or a flue open into a hor1 zont al fine 15 that connects a particular vertical flue or flues at one. end of the oven with a similar flue or group at the opposite end of the oven, horizontal walls or partitions 16 being employed to provide the horizontal fines and the lines from the end of the oven toward the center thereof, being, preferably, shortened, so that the cross or connecting fines 15 may extend horizontally from end to end of the oven. For each subdivision of the combustion chamber 12 there is a gas burner 17, each vertical flue or of flues thus having its own burner. It wi 1 be seen that by my arrangement, whereby the vertical ilues are divided into groups an the ilues at one end of the even being connected by independent horizontal ilues with the ilues at the opposite end-of the Oven, the flues in one location in no degree impair the the products of combustion from one subdivision of the combustion chamber ass upward through the vertical flues which ead from the respective chambers and do their center of the oven or at the extreme ends thereof, the result beingthe complete con trol of the heated products of combustion and the uniform heating of the even.

I, of course, do not limit my invention to any one construction of furnace.

Having thus described my invention, what I claim is:

1. A coke even having vertically extending flues at opposite ends thereof, and horizontally extending ilucs connecting the lines of one end with the flucs at the opposite end, the vertically extending flues connected by the horizontally extending flues being independent of othcrllues at the same end of the oven.

ing flues, a series of independent combustion chambers from which the vertically cxlend= ing flues lead, and horizontally extending flues establishing communication between i the vertically extending llues from the comoperation of the ilues in another location, and

full duty, whether such ilues be toward the 2. A coke oven having vertically extendbusrion chambers at one end of the oven and the vertically extending flues at the other end of the oven.

3. A coke oven having vertically extending fiues divided into groups, an independent combustion chamber for each group, from which the vertically extending flues lead, and horizontally extending Flues connecting the groups of flues at one end of the oven with the groups of fiues at the opposite endfthe combustion chamber for each group, from which the vertically extending flues lead, horizontally extending flues connecting the groups of fines at one end of the oven with the groups of fines at the opposite end, the groups of vertically extendlng flues connected by the horizontally extending flues, being independent of the'groups at the same end of the oven, and a, regenerator.

In testimony that I claim the foregoing I groups of vertically extending flues. coni ha e hereunto set my hand.

nected by the horizontally extending fiues, being independent of the groups at the same end of the oven. l
