TUBULAR HEATER, 800.
SPECIFICATION forming part of Letters Patent No. 626,924, dated J line 13, 1899. Application filed December 20,1897. Serial No. 662,515. (No model.)
To all whom, it may concern:
Be it known that LVICTOR CLEMENT JOSEPH ORTMANS, a subject of the King of Belgium, residing at Brussels, Belgium, have invented certain new and useful Improvements in Tubular Heating, Evaporating, Condensing, and Cooling Apparatus and Tubes Therefor, of which the following is a specification.
My invention relates to tubular heating and liquid evaporating as well as to condensing or cooling apparatus, and more particularly to the peculiar forms and constructions of the tubular members embodied in and forming part of such apparatus.
The features herein described and claimed are distinguished from those set forth in my pending application for United States patent, Serial No. 594,927, in that the former relates particularly to the construction of combination-tubes from portions joined together longitudinally in such manner as to thereby produce from parts having non-continuous crosssections throughout or at least along parts of their lengths structures having continuous cross-sections and embodying and inclosing two conduits independent of each other.
An object of my invention is to so construct apparatus of the character described that with an expenditure of a given amount of material and within a given space there may be obtained as large heating or cooling surfaces as may be required, suitably disposed so as to produce economical and rapid results in a small space.
A further object is to construct multiple tubular members comprising a part of such apparatus in the most suitable form and without being compelled in preparing the work to resort to the use of complicated and expensive machinery.
Iaccomplish these and other useful objects by the means hereinafter specified, and set forth more particularly in the claims.
In the accompanying drawings, forming part of this specification, and wherein like letters and numerals of reference refer to correspondin g parts, Figure 1 is a vertical cross-section of an apparatus constructed according to my inventiomand Fig. 2 a horizontal cross-section along line 2 2 of Fig. 1. The subsequent figures,drawn to a larger scale,illustrate forms ofcombinatiorrtubes which may be employed in the apparatus, Fig. 3 being a side elevation of my preferred form, Fig. 4 showing the two members forming the tube placed apart or in their condition priorto being united or joined together, and Fig. 5 a vertical section along line 5 5 of Fig. 3. Figs. 6 and 7 are horizontal sections along lines 6 6 and 7 7, respectively, of Fig. 3. Fig. Sis alongitudinalsection of another form of combination-tube constructed according to my invention, and Fig. 9 a cross-section along line 9 9 of Fig. 8.
The numeral 10 indicates a metallic cylindrical shell such as is commonly used in boilers, evaporators, and condensers, and 11 and 12 are plates secured between proper flanges provided on sections of said shell. Said plates form heads, into which'the ends of combination-tubes of any proper form; such as 13 and 14, are tightly inserted.
15 and 16 are ports in the end portions of the shell for admission and discharge of the heating or cooling agent, respectively, and 17 and 18 ports in the Walls of the shell for admission and discharge of the fluid which is to be heated or cooled, as the case may be.
Referring now to the preferred form of my combination-tube, (indicated by 13,) the same consists of two members a and b, substantially corresponding with each other in form and general construction, each member forming an independent tube opened up laterally near its ends, where it faces the other member, and provided with a U-shaped flange, which so corresponds with the opposite flange on the other member that said flanges can be brazed or otherwise permanently joined together, so as to form there a proper water'and air tight joint.
The flanges on member a are indicated by a and a and those on member Z) by Z) and b They are shown here to extend toward each other in directions parallel with the plane in which the axes of the two members are located, so as to bring their end faces, which are to be brazed or welded together, parallel with each other. It will, however, be seen that adjoining or connecting flanges might be made to overlap each other before being brazed or otherwise permanently joined together. The cross-sections of the two members are semicircular at the ends, so that the ends of the combination-tubes where they are sprung'into heads 11 and 12 are exactly circular, thus permitting of the use of the ordinary tools commonly employed for making the joints between boiler-tubes and the heads to which they are secured.
The outer portions of members a and b between the U-shaped joints above referred to, which portions are constructed as independent tubes, are along their outer surfaces of the same configurations as the ends, while their inner surfaces are much flattened and nearly parallel to each other, so as to give to the combination-tube'the general appearance of a common tube having a narrow central longitudinal slot passing through the portion between heads 11 and 12.
When the fluids passing through the apparatus are subjected to high pressures, the different portions of the combination-tubes should be made of different strengths and thickness, according to the relative strains to which they may be subjected, the interior flattened portions being in such cases made heavier than the outer portions, which are of substantially circular cross-sections.
It will be seen that a combination-tube so constructed offers a greatly-increased extent of heating or cooling surface as compared with an ordinary tube of corresponding outer diameter, the sides of the interior cross passage or channel 0 produced between the ends of said tube representing in such a construction as here illustrated a gain in heating-surface approximating about sixty per cent. It
tion as illustrated the longitudinal as well as the cross passages are substantially straight,
In the combination-tube 14, as illustrated in Figs. 8 and 9, two tubular members d and e are so brazed, welded, or otherwise joined together that their combined outer surface corresponds with that of a tube of ordinary construction, the smaller interior tube (2 being deflected laterally, so as to meet and join the edges of a lateral perforationin exterior tube at near the points where the latter enters into and connects with heads 11 and 12. this caseboth the heating and cooling agent, as well as the fluid to be heated or cooled, are conducted along the exterior and interior walls of combination-tube 14, and thus the effective heating or cooling surface may be increased by this construction fully sixty per cent. as compared with an ordinary tube of circular cross-section.
It will be seen that in the structures last described longitudinal U-shaped joints between the two sections of the combinationtube are also employed. Such joints and curved joints in general are much stronger than straight joints would be and in that respect add materially to the strength of the combination-tube as comparedwith such a tube having straight joints.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In an apparatus of the character del scribed, the combination with suitable heads, of combination-tubes provided with two infterior conduits except at the ends which have but one conduit, each combination-tube con- 1 sisting of two members, tubular except at the ends where said members open laterally on the sides facing each other and have corresponding U-shaped flanges secured together itO form a single complete conduit, substan- ,tially as set forth.
will also be observed that under the construcj 2. As a new article of manufacture, a combination-tube comprising two tubular members joined together at one end, each of the :members at their junction having a lateral openingin its circumference, one of the members being provided with a U-shaped flange forming the lateral opening in engagement with proper surfaces on the other member, substantially as set forth.
3. As a new article of manufacture, a combination-tube comprising two tubular mem- .bers joined together at one end, each of the members at their junction having a lateral :opening in its circumference formed by a U- shaped flange, the two flanges being brazed or Welded together,substantiall y as set forth.
