Pum; ,GQNDUGTIG PIPE. APPLIUATION FILED UG. 29, 1902-.
f WJTNESSES.- 77 @Him The features thus far described are com mon to the different forms of my invention; but in other respects they diier one from the other. Thus in the form of invention illus- 'trated in Figs. l, 2, and 3 the casing is experforated lugs or danges S, through' which'v pass the bolts 9, by which the sections are connected together, such flanges orlugs being in this instance carried by the casing member the ends of the sections, the packing being so disposed as io leave free openings between adjacent ends'of the pipes 2 and the openings '5 into the annular chambers 7. i
In the form of my invention illustrated in,I
Figs'. 4, 5, and 6 the end walls 4' of the 'casing 8 are set back somewhat from the ends of the section, and the openings-5 into and from heannular chamber 7 are formed in bosses 1.0, disposednpon the out-eide of the tube 2 and between the end Walis 4 of the casi-ug andthe perforated fianges 8 of the section.
in this embodiment of my invention the end walls are carried by the tube members 2 'of' ythe section, as are also the perforated lianges 8. It will also be observed that the bosses 10 are integral with the inner tube 2 and the openings into the annular chamber 7, extending out iiushwith the end faces ci' the s'Scn tion.
The form of my invention -illustrated in Fig. 7 is quite similar to that shown in Figs.
l, 2,and 3. It differs, however, in that the openings 5 into and from the annular chamber 7 are circular in form' and are adapted to receive the double tapered connecting-nipples 11. Under some circumstances it is desirable to thus unite the chambers.
It will be obsered that in each form of my invention the apertures for the connecting- -bolts 9, by which the sections are united, are
situated outside of the casing 7, thus leaving the connecting-bolts entirely exposed and -easily accessible, so that a section of the conduit maybe easily removed and another put in its place should circumstances require it.
The uses to which my invention may be put are many. For/example, thc pipe or conduit 2 may be used as a Ventilating-pipe to convey foul. air from an apartment, and cooling-Water may be caused to circulate through the connected chambers 7 in order to reduce the i temperature of the air passing through the pipe and induce a strong ilow tlierein, or the pine 2 may be usedto convey steam from a generating,r plant to a heating system or engine located a long distance away from the generatipg plant, and the connected chambers in such cases may be arranged to receive steam. or a heating medium that operates to maintain the temperature of the steam being conveyed through the pipe 2. Other instances of the use of. my invention might here be cited, but it is not thought necessary.
Having -described. my invention, what l I claim, and desire to secure by Letters Patent,
ll. A conduit for tiuids formed of sections that are duplicates of each other, each section having au interior tube'member, a surrounding casing'member forminga chamber outside of the said tube member and end walls for the chamber, integral with one of the said section members, there being openings into the chamn ber for thepassage of a circulating medium,
= and each section being provided with means 3. Suitable packing 6 is arranged between whereby it may beconnected with correspond'- ing sections, substantially as set iorth.
2. A conduit for iuids formed of independ;
ent sections, each section having a main inj terior pipe, a surrounding casing inclosing an annular chamber about the Vpipe, and -end walls for the annular chamber through which are formed openings arranged to register with corresponding openings in adjacent sections whereby the chambers of the adjacent sec tions are connected, and th... sections being 1 also provided with perforated flanges Whereby they may be united by bolts, substantially as set forth.
3. A conduit for iiuids formed of independent sections that are duplicates of each other,
each section having a main conduit or pipe,
a casing inclosiug'a chamber about the pipe and end walls for the chamber, the chambers of the conduit being connected in series, and
y each section being provided with perforated ico anges by which they may be bolted together,
such auges beingfsituated outside the casing, substantially as set forth. v
4. AA conduit for fluids formed of sections each having an interior pipe or tube member,
and a surrounding jacket inclosing a chamber about the tube, the chambers of the sections being connected in series, and each casing being united with the tube member rigidly, whereby relative longitudinal movements of the casing and tube members are prevented, substantially as set forth.
5. A conduit for uids formed of sections that are duplicates of each other, each section comprising an inner tube member 2, a 'jacket 3 surrounding the tube and inclosing a chamber about the same, end walls for the cham'- ber formed integral with one of the said section members and connected with the other by a screw-threaded joint, such end wall being provided with apertures 5, and perforated flanges or lugs Sarranged outside of thecas ing to receive the connecting-bolts 9, substantially as set forth.
