Specification of Letters Patent.
i-atented April 17, L906.
Applicationfiled June 11 1905. Serial No. 263,311.
To all whom it may concern.-
Be' it known that I, FREDERICK JOSIAH OLINcH Jonfzs, a subject of the King of Great Britain, residing at 12 Claremont road, Leamington, in the county of Warwick, Eng
'. land, have invented new and useful Improve ments in. Ap aratus for Heating Metals, of which the fol owing is a specification.
This invention relates to the heating of metalssuch, for instance, as steel-and has for its object to avoid in a more effectual manner than heretofore the oxidizing or decarboni'zing effects by which ordinary heating processes are attended.
The invention comprises the heating of the metals in an atmosphereof unignited-producer or other combustible gas or vapor which is superheated to a temperature at least as high as that to which it is required to heat the metal exposed to its influence and the employment for the formation of the said atmosphere of a portion of the gaseous fuel generated for supporting the combustion whereby the heating efiect is obtained.
Referring to the two accompanying sheets of explanatory drawings, Figure 1 is a sectiona side elevation of one form of reheatingfurnace whereby this invention is carried into effect. Fig. 2 is an end section on theline A B, Fig. 1, while Fig. 3 is a sectional side elevation on the line 0 D, Fig. 2.
- The same reference-letters in the different views indicate the same arts.-
The metal articles to e heated are placed the muffle a. Around the muffle are arranged flues b, communicating with the combustion-chamber c. The gaseous fuel is conducted through the furnace by way of 0011- I duits d, circuitously disposed adjacent to the combustion-chamber c and terminating in the mufile a. When producergas is employed, the generator, as e, is preferably con struoted in conjunction with the furnace, as shown. v
For the withdrawal of some of the gas from the conduits d to effect by the combustion of the same the superheatin of the gas going to form the atmosphere in t e-muffle a and also the maintenance of the muffle at the requlred temperature a number of by-passages f are formed between the lower portion of the conduits d and the combustion-chamber a.
A portion of the gas from the generator e escapes by way of the said by-passages into the chamber 0, where it is ignited, the necesair for the support of combustion being sary admitted through a channel 9. The remaining portion of the gas is not ignited; but during its passage to the mufilea it is superheated by the heat of the combustion in thechamber c and is maintained at the required temperature when in the muffle by the hot products of combustion as they pass through the flues b to the chimney h. v
For the purpose of excluding air from the interior of the muffle a the gas is admitted thereto at a slightly higher pressure than that of the external atmosphere. The metal or metal articles absorb heat from the gas; but no oxidation or decarbonization takes place.
Having thus described my invention, what I claim as new, and desire to secure by Let .ters Patent, is
1. In means for heating metals without oxidation or decarburization of the same, the combination consisting of a muffle, a combustion-chamber surrounding the muffle, super heating-conduits adjacent the combustionchamber and communicating with the interior of the mufiie, means for supplying combustible gas to said conduits, passages between the conduits and the combustion-chamber for supplying gas to said chamber and an air-supply to said chamber.
2. In means for heating metals without oxidation or decarburization of the same, the
combination consisting of a muffle, a combustion-chamber below the same, passages con nected to said chamber and surrounding the muffle, superheating-conduits placed on each side of a part of the combustion-chamber and communicating with the interior of the muffle, means for supplying said conduits with combustible gas, passages connecting the conduits with the combustion-chamber and an air-supply to said chamber.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
FREDERICK JOSIAH ULlNCll-JONES.
