'01! SYRACUSE, NEW YORK, A COBPOBATION OF PENNSYLVANIA To all whom it may concern: 1 Be it known that 1,,Euonnn W. KING, -a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Im rovements in Heatin Arrangements for tort Coke-Ovens, o

.throughout the block of ovens.- Below each --of'the ovens are located two regenerators,lt,

R built of checkered brick work in any usual manner; The regene'rators R, R ,-are connected by passages, P, P, with flues F, F, which are connected atone end through reversing valves, V, V ,'with an outlet passage, G, forthe waste gases of combustion,

leading to a stack, not shownin the drawin and at the other end through reversiif e,

va ves V, V", with an air inlet passage, The gassaxges P, P, are controlled. by dampers by means of which the effective orifice of the passages may be controlled, or, From each of the regeneratorsof'one set, as R, a passage, 0, formed in the division wall between two adjacent sets; of heating flues, leads u ward and is connected with the uppermost 'ues, 1, of the. adjacent sets of heating flues. From each of the other set of regnnerators, as R openings 0 connect wit the lowermost heatin iiues, 5.
