To ZZ whom it may concern.
Be it known that I, Gnsrav PETERSON, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Furnaces, of which the following is a specification.
This invention relates to furnaces especially designed for the heat treatment of spring steel wherein ahigh and uniform temperature is necessary for thoroughly heating the steel to make of the same a refining the increases the same to more readily carry the loads for which it is degrain of the material which gdgncd and withstand the shocks incidental to: the use thereof.
Une of the objects of the invention is to provide a furnace in. which the material betreatedis heated by radiated heat, the
material being in a chamber that is entirely surrounded by'the heat fro n the furnace. Another object is to provide means whe'reby all parts of the heating chamber have the same degree of high temperature. and
' from.
also to provide means for excluding the oold air from-the heating chamber, when the charging door thereof is opened incidental to the operation-of placing material in the chamber or remov ng the same there- Still another object of the invention is to provide means whereby the heat from the treating chamber is shunted away from the perator in charge of the furnace.
l lnother object of this invention is to provide a heat treating chamber wherein steel'treated is not'subjected to the usual loss of material, through the formation of scal which is always found when the flames come in direct contact with the steel.
With theebove and many other objects in'view, which will morereadily appear as the nature of the invention is better understood, the same cdnsists of the novel constructiom'combin'atioii and arrangement of parts. as will be hereinafter fully illustrated, pointed out, and claimed.
In the accompanying" ,drawingsFigure l is .topplan view of the improved furnace,
' 1s a'viegw' in front elei 'ation, in vertical section. Elg. '3 sectional view taken on the line 3-3, Fig. 2.:
shown partly in horizontal section. Fig. 2 shown partly 3 is a horizontal I preferably 14" charnbe the line H, Fig. 2.
Like referencenuinerals designate corresponding parts throughout the several fig 'u'res of the drawings.
Fig. 4: is a vertical sectional View taken on specification of letters Patent. Patentgfl Augg13, i912 vided with a bed 10, and the top being-in the form of an arch 11, the bricks of which are ofi-set'to provide a plurality of rows of staggered openings 12. Access to the chamberS is had through the front doorways 13 equipped with vertical guides 14, channel bars, in which the doors are slidably mounted. The doors 1&
areop'erated by the counterweightedlevers' 15, which have link connections 16 there- An arched heat conducting passage 17380 extends transversely across the top of chamher 8; said-passage discharging into a vertical passage 18 that extends-down one side of said chamber 8 and communicates with a plurality of parallel lower passages or subfiues 19 that extend transversely beneath chamber 8 and discharge into a assage20 ending to a chimney or other out et 21.
The heat is furnished by mixture of vcrude'oil and air and include the oil pipes 22 and air pipes 23, each equipped with a controlling valve 24, the air pipes 23 having their nozzles 25 within the nbzzles 26 of the oil pipes, and the being within the nozzles'27 pipes 28. The blast pipes 28 are provided with the regulating shutters 29, and the nozzles 27 of said p pes lie within the inlet ports 30 of the mam combustion chamber 30 which sage 17. 1
mDfiecting bridges 31 are arranged so as to separate the combustion chamber 30 from the heat conducting passage 17 to break up the volume of heat and cause the same to is a part of the conducting pasthoroughlyheating all parts of the r'8 and through openings 12 and tiou ofls'aid chamber 8 to burners using a permitting the heat to pass heat the top porthe same tempera no latter nozzles of the blast slow pass through passages l7, l8 and 19, 1 .there y or flame, to be divided ature as other parts thercot'. The outlet i ends of passages 19 are provided with controlling gates 32 having operating levers,
pivotally connected thereto that extend through openings 3t on one of the walls of casing 5. The openings are reduced at their outer ends and provided with the latching ledges adapted to be engaged by the notches 36 of levers 33 to lock the gates 32 in the desired positions. 'By the employment of the gates 32, one or any number of the passages 19 can be cut off from the chimney passage without interfering with the other passages, and the operating levers for said gates project through and beyond the exterior of the casing 5, they can be readily manipulated without the necessity of the attendant exposing himself to the heat passing through said passages 19. The main object of these gates is to pro cure means whereby the temperature of any portion of the furnace can be controlled by forcing the hot gases to tlow in any of the desired channels 19; thus balancing the temperature of chamber 8. A steam pipe 37 extends transversely across the exterior of the doors l4 and is provided with perforations 38 for discharging steam across the doorway to form a curtain t'or shielding the attendant from the heat from chamber 8 when the doors 1e are opened.
In use the material to be heated is placed in chamber 8, and the heating agent caused to circulate through 17, 1S and it) so that the said chamber is thoroughly and uniformly heated. The passages 19 that extend beneath the chamber 8 being each equipped with a controlling gateBQ, it will be seen that the heat traveling through said pas sages can be regulated to have a direct communication with the chimney 21 through the passage 19, that is in direct COUII'l'lUIliCGtlOD. therewith, or said passage cut ott and the other passages opened, thus causing the heat, and pass through all the other passages. By this arrangement, simple and practical means are provided for distributing the low of heat beneath the chamber 8 to raise or lower the temperature of any portiouthereot as may be desired.
Without further description and elaborw 5 tion it is thongl'it that th "1113 advantages of the herein described furnace are readily apparent and whatv I desire to cover by Letters Patent isl.
