SPECIFICATION forming part of Letters Patent No. 299,881, dated June`3, 1884.
Application filed August G, 1883. (No model.)
To @ZZ whom it may concern,.-
. Be it 4known that we, JOHN A. TOPLIEE, EDWARD S. Onoss, WILLIAM S. COX, and JOHN A. MOCOLLUM, of Elyria, in the county 5 of Lorain and State of Ohio, have yinvented a new and useful Improvement in Furnaces, of which the following is a'specication.
Our invention relates to that class of furnaces used for heating houses 5 and it has for IO its object to provide means whereby the full value of the fuel shall be utilized, and smoke and foul gas to a great extent prevented in burning coal.
To this end our invention consists in a cer- 1 5 tain combination and arrangement of furnaces, iiues, and dampers, hereinafter fully described and claimed, reference being had to the accompanying drawing, which is a transverse vertical section, part in elevation, looking toward 2o the inner side of the front of our furnace.
A A' represent two furnace nre-pots, made, in any usual manner, into adjacent furnaceshells a a. Around these furnaces the usual casing, H, is placed, forming the heat-cham- 2 5 ber E, from which pipes F conduct heat to various parts of the house.
C C are the furnace-doors, and DVD' are dampers to the ash-pit. G is the smoke-nue leading to the chimney. i B is a draft-flue connecting the two furnaces by passages K K', leading into their combustion-chambers, and
by passages L L', leading into their ash-pits. I is a damper pivoted at c, and adapted to stand diagonally across the draft-flue in either 3 5 direction, in order that direct communication between either of the furnaces and the discharge-nue I may beinterruptcd or opened at will.
J is a damper adapted to close either one of 4o the openings L or L'.
The operation is as follows: First make a fire in one of the furnaces-say A-allowing draft to enter by the ash-pit damper D. Vhen the coal is well coked and the fire burns freely,
make a fire in furnace A', .turning dampers I and J, as shown in the drawing, and closing the damper D, to force all the air furnished to furnace A to be drawnin at damper D'; thence through the freshly-started iire in furnace A', thence down through iiue B and inlet L. Vhen it is necessary to replenish the fires, coal will be added first to furnace A, which has been longest burning, and the dampers all reversed to force the draft in at D, up through re-pot A, down iiue B, through passage L', and up through the lire in pot A'. By this means we first re is started by passing it through a mass of burning coal. Ve thus save all the smoke and waste gases, which usually pass directly up chimney, prevent fouling the air, and utilize said smoke and gases for heating purposes.
We are aware that two furnaces or stoves have been connected together by separate fiues, each leading from the combustion-chamber of4 one furnace to the ash-pit of the other, thereby oppositely connecting thetwo furnaces, and-that a chimney has been connected with the combustion-chambers of two such furnaces; but such is not our invention, and we do not claim it. In our invention there is one flue common to two furnaces leading to tle chimney. Four openings-one above and one below each liregrate-lead into this common flue and into the chimney. f
W'hat we claim as our invention, and wish to secure by Letters Patent, is-
The combination, with two stoves or furnaces and a chimney, of asingle iiue provided with separate openings connecting with each of said stoves above and below their iire-grates and with said chimney, and dampers therein, substantially as described.
