RECEPTACLE FOR FLUID NIETL.
Specification. of Letters Patent.
Patented Dec. 11, 1906.
Application tiled March 3,1906. Serial No. 304,017.
T0 a/ZZ whom, it may concern:
Be it known that I, WILLIAu II. DAILEY, a
citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Receptacles for FluidnMetal,nofawhichnthe,following isa full, clear, `and exactdescriptionureferencebeing khadtothe Maccompanying drawings, forming a part hereof. l. g, My invention has relation to receptacles for molten metal discharged from cupola and other furnaces, and it consists in the novel construction and arrangement of parts more fully set forth in the specification and pointed out in the claim. i
In the drawings, Figure l is a middle vertical section of my invention, showing the same connected to the discharge-spout of a cupola-furnace. Fig. 2 is a horizontal section on line 2 2 of Fig. l, this view also showing the receptacle in section 5 and Fig. 3 is a vertical section taken through the dischargespout leading from the furnace to the receptacle on the line 3 3 of Fig. 2.
The object of my invention is to provide a receptacle for receiving the molten metal discharged from a cupola-furnace for foundry purposes, the primary obj ect being to eliminate from the metal all impurities of the nature of slag, dirt, and fuel particles previous to the discharge of the metal into the receptacle.
A further object is to maintain the temperature of the contents of the receptacle sul'liciently high to preserve the fluidity of the metal until such time at it may be used for the production of castings or ingots.
In detail the invention may be described as follows:
Referring to the drawings, l represents the lower portion of a conventional cupola-furnace, 2 the wind-pipe therefor, and 3 the twyers, all of the usual and prevailing construction. Located adjacent to the cupola and at a level below the discharge-spout 4 thereof is a casing 5, provided with a bottom door 6, through which access may be had thereinto for purposes of cleaning. Mounted on suitable posts or brick supports 7 on the bottom of the casing is an open receptacle 8, whose upper end is in communication with the spout 4 aforesaid, whereby the molten metal from the cu ola discharges directly into the receptacle, t e spout penetrating the wall of the casing 5, as shown'mWithin the spout is located a fire-brick screen or filter 9, disposed at an incline whereby any foreign matters-such as slag, cinders, fuel particles,andlumps of carbon-are intercepted, the pure metal freely passing through the openings of the screen and through the spout into the receptacle. The latter has a discharge pipe or spout l0, which is closed by a gate or valve ll. y
Flncompassing the casing is a pipe 12, from which lead into the casing a series of nozzles 13 for spraying suitable quantities of oil or hydrocarbon into the casing, the said hydrocarbon being ignited at the high temperature from the fluid metal in the receptacle, the pipe l2 being supplied with oil from a pipe 14, leading to any source of supply. (Not shown.) The air for maintaining the combustion of the hychocarbon within the casing is supplied by the shunt or branch l5, which leads from the wind-pipe 2, the combustion products being conducted out of the casing through the eduction-pipe 16, whose one end taps the casing approximately ninety degrees from the discharge end of the branch 15 and whose opposite end discharges the combustion products back into the cupola in a plane on a level with the twyers 3. The combustion of the hydrocarbon in the casing around the receptacle maintains the temperature within the casing sufliciently to preserve the fluidity of the metal within the receptacle until occasion demands its withdrawal through the spout l() for foundry purposes. As cinders, slag, fuel, and other impurities accumulate in the spout 4 they may be removed from time to time upon opening of the lid or door 17, with which the top wall of the spout is provided, any poke-bar accompl-ishing such removal, as is apparent to any foundryman or the skilled mechanic.
It will be seen that the same source of airsupply which furnishes the blast for the twyers is utilized for supplying oxygen to the interior of the casing for purposes of maintaining the combustion of the hydrocarbon introduced thereinto. The inclination of the screen 9, while effectively intercepting the light impurities, yet freely permits the molten metal to pass through the openings thereof.
I-Iaving described my invention, what I claim is In combinationwith a cupola having a dis- IOO IOS
charge-spout, a Wind-pipe and tWyers, a remeans for supplying a hydrocarbon to the ceptacle communicating With the spout, a casing, substantially as set forth. Io
easing surrounding the receptacle, a branch In testimony whereof I aliX my signature or shunt leading from the Windepipe to the in presence of tWo Witnesses.
Chamber of the easing, an eduotion-pipe lead- WILLIAM H. DAILEY.
