SPECIFICATION forming part of Letters Patent No. 530,893, dated December 11, 1894.
Application filed September 18,1894- Serial No. 523,366. (No model.)
To all whom it may concern:
Be it known that 1, CHARLES F. H001), a citizen of the United-States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Extracting Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to means for extracting volatile and oleaginous substances, or such as are readily converted into vapor by application of heat through operation of an apparatus consisting of certain novel and useful mechanism and combinations thereof, as hereinafter fully described and illustrated in the drawings. I
My invention principally relates to treatment of cast 0E cotton and wool, also to extraction of fatty substances from leather refuse from factories and tanneries, but its operation and practice is not limited thereto, as its object and purpose is to obtain from any suitable substance or material, certain extracts by placing such materialin a closed tank and vaporizing the same by subjecting it to the action of vapor steam and air, maintained at a suitable temperature, and condensation of said extracts by means of steam, the aerated vapor being discharged into the mass of material under treatment, by means of perforated coils in the tank chamber of the extractor.
Referring to the accompanying drawings, of this specification, wherein like figures ofreference' point out similar parts on each view, Figure 1. is a diagrammatic view of the entire apparatus, certain parts being broken away, to show interior construction. Fig. 2. is a top plan view of one of the perforated coils. Fig. 3. is a vertical section through the lower part of one side of theextractor showing structure of the jacket that surrounds the same, and arrangement of inner supports for substance under treatment. Fig. 4. 's a detail view of a portion of the air and vapor pipes showing connections thereof with casing of the extractor.
In the drawings, 1, is the extractor, the main body of which is cylindrical, at or near the upper edge of which is riveted or bolted the conicaltop, 2. At or near the lower end of extractor, 1, is secured, by bolts or rivets, in a well known manner, the inverted cone shaped bottom, 3. The upper and lower oppositely inclined inclosures are shown as conical, but may be dome shaped, without departing from the scope and purview of my invention.
he cylindrical chamber of the extractor, 1, ismounted on supports of suitable conformation, illustrated in the drawings as vertical uprights, bolted to flanged brackets, 5, riveted to lower portion, 3, of the extractor. steam jacket, 6, of usual rounds the main body. Near the top of the jacket, 6, is a pipe or tube, stop cook, 8, for admission of live steam to the inside of the jacket. A similar pipe, 9, is arranged near the lower end of the jacket to be used as a drip, or for drawing ofi the exhaust. Below the jacket two annular flanged bands, 10, 11, surround the cylindrical body, which are secured together by bolts, 12, passed vertically through apertures in said flanges outside of the cylinder. The upper band, 10, has a sectional or continuous bracket, 13, connected to it, and to the body of the cylinder on the inside, for a purpose presently pointed out. The lower band, 11, has an annular re-- cess, 14, in the top thereof, into which is inserted a lead gasket to form secure packing for the joint.
At the upper section 2, of the extractor is arranged. a charging door, 15. This door comprises a rectangular frame, 16, having at two sides thereof upwardly projecting bifurcated lugs, 17, between which is pivoted an arm or latch bar, 18, by means of pins or toggles, 19, passed through said lugs. The bar, 18, is'tapped vertically near its center, to reconstruction, sur- 7 provided with a ceive screw bar, 19, on the outer end of which closure can be maintained .by rotation of the The under side of the covhand-wheel, 20.
ering plate and the top of the frame are provided with suitable packing or gasketsto prevent leakage or escape of air or vapor.
I have shown the closing plate as rectangular, but it may be circular or of any suitable form. A similar door, the parts of which are the same as that just described, and are identified by same reference numerals, is arranged near the bottom of the cylindrical chamber of the extractor for removing the stock therefrom after it has been treated, or for withdrawal thereof, in whole or in part, at any stage of the process.
Just below the lower edge of the door, last above described, and resting on the brackets, 13, on the inside of the cylinder, is a tray or frame consisting of radial angle arms, 22, which is the preferred form but no special form of tray is essential. Supported on this tray is an annular frame, 23. This frame is covered on the top or bottom, or on both top and bottom, with wire netting or other foraminous material, and upon this netting the stock or substance to be treated, in accordance with my invention, is deposited through the charging door, 15. Connections or couplings, 24, are provided at both the top and bottom, or conical ends of the tank, of the extractor and connect with suitable pipes, as hereinafter explained.
Within the lower portion of the extractor are arranged three coils of pipes, the upper one for vapor, the next for air, and the lower one for steam.
25, is the vapor coil, consisting of a single convolute pipe arranged horizontally within the extractor nearly coincident with the lower external band, 11. The pipe or tubing of which it is composed is pierced or perforated on top at intervals as seen at 26, Fig. 2, for the emission of vapor led therein from a vaporizing tank. The end of this coil passes through the wall of the extractor, suitably packed, and on the outer extension is a stop cock, 27.
The air coil,28, is of the same construction as the vapor coil and is arranged horizontally underneath it. It also extends through the wall of the extractor and has a stop cock exterior thereto and from thence is prolonged to any proper source of supply.
The steam coil, 29, difiers from the vapor and air coils in that it consists of a series of continuous spiral convolutions which diminish in size toward the bottom of the extractor and conform substantially to the shape thereof. It is imperforate and its upper end like the vapor and air coils is passed through the wall of the extractor and has a stop cook, 30, on its outer extension, and is connected with a suitable source of supply. The lower end of the tube forming the steam coil, 29, is extended diagonally through the bottom of the extractor and has a stop cook, 31, for drawing oif the water of condensation therefrom.
Arranged at one side of the extractor is a vaporizing tank. It consists preferably of a vertical cylinder, 32, constructed to be steam tight .and containing a spiral coil, 33, for receiving and containing steam. At the top of the tank is an outwardly extending vertical pipe or tube, 34, provided with 35, through which pipe any suitable vaporizing fluid or material is fed into the tank. A lateral pipe, 36, provided with a stop cook, 37, supplies'the coil, 33, with live steam. Adrain pipe, and stop cook, 38, is arranged at one side of the tank, at its lower end for emptying the same and a second pipe and stop cook, 39, at the opposite side for drawing off water condensation from coil 33. At one side of the tank is a water glass, 40, to indicate pressure. It comprises the ordinary gage glass and scale with stop cock and other connections commonly used on analogous devices. Projecting upwardly from the top of the tank is a pipe, 41, for conveying vapor from the tank to the vapor coil in the extractor and is connected to the pipe which feeds said coil by coupling, 42.
On the side of the extractor opposite the vap, orizing tank, is a condensing receiving tank- 43. It is of usual construction and consists of a vessel open at the top, with adjustable cover if desired, adapted to contain water and having inside a tubular coil, 44. The lower end of this coil extends through the wall of the tank and is provided with a stop cook, 45, for drawing off the extract which has been vaporized and condensed. The end of the coil, 44, is carried beyond the top of the tank, 43, and connected to the vapor conduit which is a bent and inclined tube, 46, attached by coupling, 47, to pipe extending from top of the extractor. The condensing tank, 43, is mounted on any base, or supporting frame, 48.
A tube or pipe, 49,is connected to the bottom of the extractor and is provided with a stop cock, 50, for discharging waste or dbris that may accumulate therein, and as will be readily understood can be utilized for cleansing purposes.
In the drawings the vaporizing tank is shown to the left of the extractor and the condensing cylinder to the right thereof, but it is manifest that the apparatus will operate it the relative location of the several membars are reversed or arranged at suitable distances apart.
From the foregoing description, in connection with the drawings, the practical operation of my invention will be readily understood by all familiar with the class to which it is allied.
The stock, or material to be treated, is introduced into the extractor through the charging door at its upper end and will fall upon the netting or foraminous tray, and after the requisite quantity has been introduced, the charging door is hermetically closed. Preferably solvents such as benzine or other are employed for producing vapor, but I do not desire to limit my process and apparatus thereto as there are many other materials,

both solid and fluid, that can be used forgencrating vapor either separately or in combi-' nation, in carrying out the object and pur- A fluid or suitable vapor generating material is fed into the vaporizing tank through the vertical supply tube, 34, extending upwardly therefrom, and from thence passes downwardly within the coil, 33, the quantity to be introduced being from time to time regulated by operation of stop cook, 35. Steam is then introduced through the feed pipe, 36, and allowed to flow for any desired period by operation of its stop cook, 37. As vapor is thus generated in the tank, 32, it passes upwardly through the eduction pipe, 41, to the vapor coil, 25, from whence it is discharged or. atomized by means of apapertures in top of said coil, and through the intervention of heated air, produced by steam admitted in the steam coil, 29, and atmosphere passing outwardly through orifices of the air coil, 28. The aerated vapor circulates through the stock mass deposited on the foraminous tray and the extract charged with material withdrawn, from said stock, is carried to the top of the extractor and from thence passes down through the outlet tube, 46, into the coil, 44, in receiving tank, 43, and the product is drawn ofi by means of stop cook, 45. The residuum remaining in the extractor is removed through the door at bottom of the main chamber.
I do not limit operation of my invention to a given pressure or continuous flow of steam, or air, into the extractor, nor to any special quantity or character of vapor generated in the tank, 32, as each will depend upon the nature, quality and quantity of material to be treated, and it will be readily understood that the generated vapor can be changed and always governed by the nature of material from which it is to be eliminated, and the supply flow of air, steam and vapor can each be regulated and controlled by partially or completely opening the conduits to the main chamber of the extractor.
The quality of residuum drawn off through the stop cook, 44, depends naturally on the character of the stock treated in the main cylinder, and may be subsequently treated by analysis or any suitable process, to separate ingredients thereof or utilize it in the condition drawn off for any desired purpose.
Having thus fully described my invention and the manner of its operation, What I claim, and desire to secure by Letters Patent of the United States of America, is-
1. In an apparatus of the character described, a cylindrical extractor provided with an interior foraminous supporting tray for material under treatment, vapor, air and steam coils, arranged, one above the other,
under the tray, in combination with an exteriorrvapor generator, connected to inlets of the extractor, and a condenser connected to outlets therefrom, substantially as described.
