EVAPORATING-COIL.
SPECIFICATION forming part of Letters Patent No. 380,050, dated March 27,1888.
Application filed April 19, 1887.
To all whom it may concern:
Be it known that I, WILLIAM H. ODELL, a citizen ofthe United States, residing at the city of Yonkers, county 'of Westchester, and State of New York, have invented certain new and useful Improvements in Evaporating-Coilsof which the following is a specification.
The object of this invention is to compose a system of inclosed pipe-coils which are readil ly separable,so that a seriesof connected tubes may be readily taken apart for cleaning or repairs, or so that the units of which the structure is composed may be removed independently without disturbing' the remainder of the structure, or the entire system may be removed,section by section, through a man-hole from or into the interior of a shell whence it is desired to place the coil. Y
The separable feature of the pipe-connections renders them especially applicable for use in evaporating-tanks wherein in heating liquids that contain scale-forming impurities the entire surface of the coil becomes coated with hard scale, and readiness of removal for cleaning becomes au important feature.
Referring to theaccompanying drawings, in which like letters indicate like parts throughout the several views, Figure l is a longitudinal sectional view of an evaporatingtank, showing the tubes in elevation withinv the shell; Fig. 2, a front elevation of the tube-connections, the shell of the tank being in crosssection; Fig. 3, a corresponding rear elevation; Fig. 4, an enlarged sectional view of a tube, header, and removable return-bend; Fig.
5, an elevation of the same taken at the opposite end of the same tube5Fig. 6, a frontview of areturn-bend, and Fig. 7 a detail View of the bolt used in fastening the return-bends to the headers.
In Fig. 1, A is the shell of the evaporator.
B B are man-holes 'for obtaining access to the tubes and through which the sections of coil can be introduced or removed.
C is a steam-pipe for supplying the coil.
It will be observed in Fig. 2 that the steampipe connects, by means of the transverse tube D and branch pipes E, to each of the upper series of headers a of the coils.
Serial No. 235,306. (No model.)
' F is a drip-pipe for conveying away the wa- 5o ter of condensation from the lower sections of the coils.
G is a nozzle for carrying off the vapor of Y the liquid under treatment.
His aninietfornquidtothefank. 55
I is an outlet for the liquid when suiciently treated.
J is an outlet for emptying thetank or blowing off from time to time any collection of impurities. 6o
present illustration the tubes b are so con- `65 nected tothe headers in pairs. The ends of the tubes are secured to the headersby expanded joints or other suitable means of fastening at c, this joint being permanent. 'Ihe removable return-bends d are secured in place 7o to the headers a by means yof T-headed bolts c, the heads of which fit in sockets f of the headers, so as to swing freely when the nuts are loosened. The nuts of the bolts care screwed up against the forked lugs g, cast on 7 5k the bends, so that the joint h between the bend and the header, 'which is preferably a packed joint, will be made thoroughly tight. Metallicvpacking composed of a ring of soft metal` is preferably employed for the joint h. 8o
Upon loosening the nuts the swiveled boltsA are readily knocked out of the forked lugs g, swinging on the pivots of their T-heads, so as to release the bends and permit their quick removal,disconnecting the units of the struct- 8 5 ure. y j
In Figs. 2 and 3 I have shown three way bends, d', as a modification of construction, which may be applied in the manner shown for connecting together the tubes' of three sep- 9o arate headers.
It will be observed that in placeof nuts on the bolts e, I may employ other tightening devices capable of being more quickly handledas,for instanee,a longitudinal slot cut through 95 the bolt near its end-fitted with a tapered key, the iiat edge of the key resting against the forked lug g.
Having thus fully described my invention, the same, said return-bends having means for what I claim, and desire to secure by Letters a ready attachment or detachment to said Io Patent, is headers,(as by forked lugs and swiveled bolts,)
In an inclosed coil, the combination of sepfor the purposes set forth. 5 arable sections composed of one or more tubes WILLIAM H. ODELL.
