FURNACE.
SPECIFICATION forming part of Letters Patent No. 375,002, dated December 20, 1887.
Application filed March 31, 1886.
To all whom it may concern:
Be it known that I, LUKE RYAN, of Apollo, in the county of Armstri'ing and State of Pennsylvania, have invented a new and useful Improvement in Furnaces; and I do hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to an improvement in metallurgical annealing-furnaces designed to be heated by the combustion of gas; and it consists in the combination of devices hereinafter described.
The construction of said furnace and its mode of operation will be readily understood from the following description, taken in connection with the accompanying drawings, wherein Figure 1 represents a side elevation of my improved furnace. Fig. 2 is a longitudinal vertical section thereof. Fig. 3 is a transverse vertical section thereof. Fig. 4 is a plan of the same on a horizontal level beneath the floor of the furnace.
The furnace I have designed may be of any suitable size or shape and provided with all the appendages and appliances'incident to and in use with devices of this character; but in order to accomplish the object of my invention I prefer a quadrangular structure, A, covered by an arching roof, B, through which one or more vertical flues, O, extend and communicate with a chimney, D, for carrying off the waste products of combustion, as shown in Fig. 2. The floor E of the furnace is built of brick and provided with a track consisting of two iron rails, f, extending parallel with each other the entire length of the furnace, and otherwise so arranged as to enable cars to run in and out of the same through doors 9 at each end thereof.
The sides of the furnace consist of double walls separated a short distance from each other to leave a space, h, between them. The exterior wall, 1., of each side is provided at suitable points with small doors F, as shown in Fig. 1, leading from the outside into-the aforesaid space h, for the purpose of inspection or otherwise, and the inner side walls, j, are perforated in such manner as to constitute a num ber of contracted passage-ways, L, as shown in Fig. 2, for the ingoing gas, either separately Serial No. 197,354. (No model.)
or mingled with a requisite supply of atmospheric air.
F are small doors formed in the end walls forming an intermediate mixing-chamber for the ignited gas and air.
Extending along the outside of and near the bottom of each exterior side wall, i, is a receiving-chamber, H, connected by suitable flues, L, with the space It existing between the side walls of the furnace, as shown in Fig. 4. Each of these receiving-chambers His provided with a series of air-passages, Z, extending thereinto and adapted to be opened and closed by a sliding cover, m, operated through the instrumentality of a suitable lever, 02, whereby the current or quantity of air entering the furnace may be regulated, admitted, or excluded.
A pipe, M, of proper dimensions for connection with a gas-well or source of gas under pressure and provided with a stop cook or valve, N, for controlling the flow of gas, is made to communicate by convenient branches, 1), with another pipe, R, arranged horizontally outside of the receivingchambers.
Projecting outwardly from each of these horizontal side pipes, R, are a number of short tubes or tuyeres, S, arranged in clusters, and through them gas under pressure is fed into the receiving-chambers H preparatory to entering the body of the furnace. The gas thus entering under pressure causes by suction a current of air to enter through the openings Z and flow directly to and mix with itself. The rapidity of its flow drives the flame or burning portion of the gas out from the opening of the small pipes and allows the air to mix with it before combustion takes place.
By a proper adjustment of the lever n the sliding covers at over the air-passages Z, leading into the chambers H, may be partially or wholly opened and air allowed to enter and mingle with the ingoing gas, which on being ignited will produce a vigorous combustion and great volume of flame, that by way of the space between the side walls and the vari- IOO ous channels will eventually enter the large annealing-chamber in a highly intense condition, soon bringing it to a suitable degree of heat useful in the manufacture of iron, the working of metals, or other requisite purposes to which it can be applied.
I am aware that it is not new to eonstructa furnace with double side walls, the inner being perforated for the passage of gases, and that the air has been drawn in to mix with the gas by the gas itself when supplied under pressure, and I do not claim these features, broadly.
What I claim is- 1. The combination, in a heating-furnace, of an outer solid wall and a perforated inner wall, a perforated partition, h, about the level of the furnace-floor and located in the space h between the walls, thereby forming an intermediate miXing-chamber, and a receiving-chamber built outside the furnace below'the level of the furnace-floor and communicating with the said intermediate chamber, and provided with inlets for gas and air communicating with the said receiving-chamber, subtantially as described.
2. The combination, in a heating-furnace, of a solid outer wall, a perforated inner wall, a perforated partition, h, about the level of the furnace-floor and located in the space It between the walls, thereby forming an intermediate mixing-chamber, a receiving-chamber built outside the furnace below the level of the his LUKE RYAN.
