VI claim: 1. In an oil orlother 'uidfcoolerlnor heatv exv 'changera of the tubular removable tulie'fy bundle type, thecombination of.fha1f cylindrical shell segments having marginal fabutting f iianges of Which the roots are spaced respectively inside and outside of the longitudinal edgesof the segments to provide` a longitudinal lap, 'half ,ring-v segments secured at the ends of the flanges and to the adjacent endsurfacs of the shellsegmentsand-of which two -aie 'channelled yfon-the ,reception of Y packing, packing in-.said channelled rin'g'isegments a packingringV secured tothe face of the channelled ring-- segments; a .tube bundle having tube sheetsY of whichoner is fixed-to thefsegments constituting one ring and is groovedfor-the reception of the. endsof the `shell. segments, andY of it isl well to state 'thatrthe which the other is movable in the shell and is packed by said packing, yheads-respectively bolted to one of the tube sheets and to one pairV of half rings, and pipe't'tings confined to one of the shell sections. Y

2. In an oil or other fluid cooler or heat exchanger ofthe tubular removable tube bundle type, the combination of VVa longitudinally split Cooler shell provided at one end with the half `segments of a ring, a tube bundle having a floating tube sheet, and a packing external of the segments. h f

3. In an foil or other fluid cooleror heat exfloatingv tube sheet and inside of said half ring chang'er ofthe tubularl removable tube bundle type, fthe -C Qmbination of a longitudinally split cooler shell Ahaving outward flanges at its edges havingnanged'edges detachably connectedtogetherand of'y which oneshell segment is xedly supported and is providedY with pipe connections andof which the other shell segmentA is removablev and devoid ofpipe connections, and a tube bundle mounted inthe shell.V

5. Injapparatus of thetype specied the combination of a longitudinally split cylindrical shell i having anged edges detachably connected Y'ton vgether and `of which one shell segment is xedly supporteda'nd is provided with pipe `connections and of` Whichtheuother shell segment is removable ,ianddevoid of pipe connections, a tube bun- "dle, mountedrin the shell,`and eyesA at the end parts of the removable shellvv segment fork attachment to, cables into the'bights of i which the shell section kcan be`rolled to aiord access to the tube bundle withoutbreakingthe pipe connections."

. 6.'V In apparatusfof the type specified the `combination of a longitudinally split cylindrical shell l having flanged edgesdetachably 'connected togethervand ofA which one shell segment is ixedly supported and isfprovidedvwith'pipe connections vandof Vwhich the other Yshell segment is removable and devoid of pipe connections, a tube bundle. mounted inthe shell, andV gussets' arranged `between the flanges and shell segments and of lWhich those at Ithev ends of .the removable shell segmentsxare providedwith rings.

Y 7. In apparatus ofthe typespecifed the comlbinationV of'semi-cylindrical shell sections each having.V marginal flanges, segmental end rings secureat the ends of the flanges fand to theadjacent surfaces of the'shellV sections and of which one is a packing ring, gussets secured tothe flanges and to the surfaceofrthe shell sections, a tube ,bundle having tubesheets of which one is fixed to one-ofV said end rings,`and of which theV other ismovablesand extractable from the shell and is packedbysaid packing.ring, and headsof which one is nbolted to one of said Yrings and o f which the otherjis boltedto the free tube sheet.
