SPECIFICATION forming part of Letters PatentNo. 723,850, dated March 31 1903.
Application filed November 17, 1902. Serial No. 131,719. (No model.)
To all whom it mag/concern:
Be it known that I, EUGENE RILEY EDsoN, a citizen of the United States of America, residing at Cleveland, in the county of Ouya} hoga and State of Ohio, have invented certain new and useful Improvements in Bendering or Reducing Tanks or Receptacles;
and I 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 pertains to make and use the same.
This invention relates to improvements in jacketed rendering or reducing tanks or receptacles, andmore especially to a tank or receptacle of the character indicated which is provided centrally and interiorly with a vertically-arranged drum depending and removably secured to the top or upper head of the receptacle and provided with an interior which, first, an inner Vertically-arranged cylindrical metal shell, which forms the surrounding wall of the main interior chamber of the receptacle and also forms the inner side wall of the chamber of the jacket of the receptacle, can elongate downwardly from expansion by heat or shorten or contract upwardly upon cooling independently of the any port-ion of the receptacle or unduly strai ning any part of the receptacle, and, second, in which the interior drum, which depends from and is removably attached to the top or upper head of the receptacle, is capable of elongating downwardly from expansionby heat or shortening or contracting upwardly upon cooling independently of the corresponding expansion or contraction, as the case may be, of the aforesaid inner shell.
With this object in View and to the end of realizing other advantages hereinafter appearing the said invention consists in certain features of construction and combinations of parts hereinafter described,and pointed out in the claims.
The accompanying drawing is a side elevation, largely in central vertical section, of a rendering or reducing tank or receptacle embodying the said invention.
' Referring to the drawing, a designates an inner vertically-arranged cylindrical metal shell which forms the main interior chamber b of the tank or receptacle, in which chamber the material which is to be reduced or rendered is digested or treated. The shell a is shaped at its lower end to form a down-- wardly-discharging opening or outlet 0 for the chamber 1), which outlet 0 is arranged centrally of the lower end of the said chamber and has an upwardly-flaring mouth d, which is formed by the inverted-cone-shaped lower end portion 8 of the shell 0.. The surrounding wallfof the outlet 0, below the mouth of the said outlet, is cylindrical, and the said outlet is normally closed at itslower or outer end by a suitably-applied door 9, which is opened whenever required to accommodate the passage of any material from within the chamber I) through the outletc of the said chamber. The shell (1. terms also the inner side wall of the chamber h of theextern'al jacket of the receptacle, and the outer side wallof the said jacketchamber is formed by a vertically-arranged outer cylindrical metal shell 1, which is of course considerably larger transversely than and surrounds the inner shell (1. The outer shell Z has a lower inverted-cone-shape'd portion m, which surrounds and is transversely larger than thecorrespondingly-shaped lower end portion 6 of the shell a, so that the chamber of the jacket'extends downwardly to and aroundthe' upwardly-flaring mouth of the outlet 0 of the chamber b. The lower end portion m of the shell 6 is provided at its lower end with a suitably-applied stuffingbox 0, which surrounds the surrounding wall f of the outlet 0, below the flaring mouth of the said outlet, and forms a fluid-tight joint around the said wall, and the chamber 19, which is formed in the upper portion of the said'wallf, is open at its upper end and forms a downward enlargement of thechamber of the jacket. The Wall f is provided with a port '1", which extends downwardly from and communicates with the chamber p and is in open relation at its lower end with a drainpipe 8, which has a normally closed valve 25. The shelll is provided also with a pipe a, which communicates with the chamber h and ICC is employed to conduct fluid into the said chamber. The pipe to is provided with a valve to.
Both shells at and Z are secured at their upper ends to the top or upper head xof the receptacle, which head isinstrumental in closing the upper end of the chamber b and extends snugly between and is secured to the upper ends of the said shells; but the inner shell a) is free to elongate downwardly through the stuffing-box 0 independently of the outer shell l.
A closed interiorly-chambered or hollow drum y is arranged vertically within and centrally of the chamber 1) and depends from the head at into the lower portion of the said chamber and is free to elongate downwardly. The drum y is removably secured at its upper end to the head as and is shown provided at its said end with an external annular flangej, and screws k, which have their heads abutting against the under side of the said flange, extend through the flange into correspondingly-screw-threaded holes a, formed in the under side of the said head.
A curved copper pipe A is arranged within the upper portion of the chamber 1) and is applied in any approved manner toplace it into communication at one end with the jacket chamber h and in open relation at its opposite end with the interior chamber of the drum y. A curved copper pipe Bis arranged within the lower portion of the chamber 1) and applied in any approved manner, so that it at one end communicates with the cham her 71 and at its opposite end is in open relation with the interior chamber of the drum y. The pipes A and B areinstru mental in forming passage-ways between the jacket-chamher h and the interior chamber of the drum y.
An air-conducting pipe D is arranged centrally of'and extends longitudinally through the drum y and below the lower end of the said drum terminates in a foramiuated head G, which is removably attached to the said pipe, having interior screw-threads which engage with corresponding screw threads formed on and exteriorly of the said pipe.
A tubular washer H, of compressible and elastic materialsuch, for instance, as cork or rubber-4s tightly interposed between the head G and the exterior of the lower head of the drum 1 and prevents the leakage of fluid between the chamber of the drum and the chamber b. The head Gforms, therefore, a nut for tightening the washer H, as well as an air-charging head for the pipe D. A nut K engages with corresponding screw-th reads formed on and exteriorly of the pipe D at and next to the inner side of the lower head of the drum y and is consequently arranged to form a stop, which prevents downward displacement of the said pipe independently of the drum, so that a snug interposition of the washer H between the said head of the drum and the air-discharging head G of the pipe is maintained. The pipe D extends above the icasso head a: a suitable distance and externally of the receptacle is connected and placed in open relation by a hose or flexible tube 1 with the outlet of a suitably-operated airpump L. The head 00 is provided with a stuffing-box R around the pipe D, so as to prevent leakage of fluid between the interior chamber of the drum and the external atmosphere where the said pipe extends through the said head.
The head as is provided at one side of the drum y with an upwardly-flanged chargingaperture T, through which the material which is to be rendered or reduced or treated within the chamber 1) is fed to the said chamber, and a suitably-applied cover U is provided for closing the said aperture. The aperture T is large enough transversely to accommodate the passage of the drum y therethrough in the assemblage or renewal of parts.
The lower inverted-c0ne-shaped end portion m of the outer shell Z of the jacket is provided exteriorly with an annular flange W, which is adapted to rest upon a base or support. (Not shown.)
Thehereinbefore-described construction, it will he observed, is simple and durable and more especially convenient so far as the assemblage and renewal of parts are concerned, and it is obvious that the interior drum y can elongate downwardly from expansion by heat or contract. by cooling independently of the metal shells at and Z; that the inner shell at can elongate downwardly from expansion by heat or contract by cooling independently of the drum and the outer shell Z, that the jacket-chamber h extends into the wallfof the outlet 0 of the main chamber 1), below the flaring mouth of the said outlet, and consequently the said wall is directly heated from any heating fluid supplied to the said jacket-chamber, and that the pipe D can shift downwardly with a downward elongation of the drum without leakage between the upper end of the said drum and the external atmosphere and without loosening of the washer H.
