Generically this invention relates to pipefittings but it is more especially directed to the type of fittingknown as a header.

The principal object of this invention is the provision of a sectional header adapted for use in connection with a pipe coil or multiplicity of pipe conduits whereby each pipe is directly connected to an individual section of the header.

'Another important object of this invention is the provision of a header of this type formed from a plurality of individual sections, each section being directly attachable to a coil section or pipe line and means for uniting the sections into a unitary structure.

A further object of this invention is the provision of a header formed with a plurality of .individual'detachable sections, relatively adjustable, each section being attachable to a coil section or pipe line at any angle with respect to the other sections, and adjustable means for uniting the sections into a unitary structure. I

A stillfurther object of this invention is the provision of a sectional header of this character having joint or closure caps at each end of the assembled structure and adjustable means interconnecting said caps for uniting the sections into a unitary structure, said means being operable to permit relative adjustment of any one of the sections withrespect to the unitary device.

With these and other objects in view, which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which like characters of reference indicate like parts throughout the several figures, of which Fig. 1 is a view in elevation of an apparatus showing my improved header operatively positioned with pipe sections broken away, said sections being shown in fragmentary elevation;

Fig. 2 is a longitudinal section of the header; and

Fig. 3 is an elevational view taken at right angles to Fig. 2.

The headers with which I am familiar heretofore in use, especially the one piece type, necessitated the employment of a union or coupling intermediate its length in every 7 lineiof pipe comprising the coil and inst-allation and subsequent repairs to the device were effected with more or less difiiculty. Therefore, it was to overcome the deficiencies of such devices by efi'ecting a saving in material' and labor incident to thein'stallation'of 6 0 7 the header and to render it easy to efiect repairs, and so forth, byfthe provision of a header composed'of cooperating individual and relatively adjustable sections, each section being directly attachable to one of the lines of pipe comprising the coil, said'pipe having male threads at its extremity for'en V V gagement with said section, the section at each endof the device being formed with a detachable closure cap, said caps having central longitudinally ali 'ned openings adapted to receive a tie-rod threaded at its-ends for cooperation with exteriorly positioned adj usting nuts, by which means the several sections are united intoa unitary structure and through adjustment of which any of the sections may be expeditiously positioned with respect to the entire device, or secured to or detached from a respective coil pipe as desired, without the necessity of disconnect ing other sections or the entire header to effectrepairs in connection with a particular coil pipe, that I designed the header forming the subject-matter of this invention.

In the illustrated embodiment characterizing this invention there is shown my improved header A and coil B. The coil B comprises a plurality of water, steam or the like pipes 5 of conventional design. The header A comprisesa plurality of tubular like header sectionsi6 formed on one side with a raised portion 7 extending beyond the cirs cumferential surface of the section and hav ing a central opening 8 internally threaded as at 9 to receive the threaded extremity of one of the pipes 5, for a purpose which will hereinafter more 1 fully appear. Said sec,- tions6, in the present instance, are formed adjacenteach. end with collar-like enlarge- H ments 10, the inner walls at the ends of each 1% section being inclined to form tapered seats 11 for a purpose hereinaftermore fully described.

An inner slip nipple or sleeve member 12 is formed with an enlargement at its center as at 13 and tapering therefrom oppositely to its ends, to form the tapered portions 14., the saicli n pple or sleeve adapted to bridge the joint formed by the meeting ends of two of the sections, the tapered portions 14 adapted to engage the seats'll of the respeetive sections when the nipple is operatively positioned to support said sections in longi tudinal alignment. A. gasket. 15 formed from copper or other suitable material is mounted on the nipple sleeve. 12 and is adapted to seat onfthe enlargement 1 3 between. the meeting ends of sections 6' sup poi-ted by said nipple, to form: a water or steam tight joint when said sections have. been. operaztively positioned, as will hereinafter appear... I

Aclosure orjoint cap lfiiis-inserted at each ended? the device, and; formed with an. annul'ar things. 11 adapted to seat. against oneof the gaskets 15 interposed between. the said flange and the-end ot the section 6. to form.

a steamer water tight joint, each 0t said" caps 1'6 being. centrally aperturedas at 18. A tie rod. 19 extendsthrough-said apertures and has its endsith-readed as at 20 to engage the interior thread of thenuts2-l when operatively positiened; thereon, and when brought. intoengagement with said. caps, adapted to draw the sections 6 toward. each other compressing. the gaskets to form non-lealrable: joints and to unite saidsecti-onsinto a unitary structures lit is obvious that any one of thesections may be: provided with inlet and outlet openings similar-to 22 or additional seetlonsinay' be? added ei-ther'end. to constitute eu-tlet or inlets. similar to the. inlet section 23,, and Whieh may be positioned at. any angle WllilL respect to the device.

it will be noted that thedevice above described is susceptible of being, easily'lnstalledl and any individua t sectionqthereof easily secured in. operativepositionr'andthe entire: device united into. a unitary structure by s mply actuating the nuts 20,. thereby drawing: the closure or joint-caps 16 toward each othersiniulta'neously eliecting engagement oztthe R tapered seats with corresponding portions of theslip nipple ormpples dependent uponl whether two sectiens'or a multiplicity 0t sections are-employed in the particular instance. r j From the" above it is apparent that have designed a header effecting elimination of unions in connecting thecoil pipes to theheader', therebfdbcreasihg the necessary dis tanc'e between'tliiecoil'. pipes and rendering the header more compact, while at the same time enhancing the appearance of the assembled device.

In conclusion, it will be apparent that I have designed a sectional header which may be employed in connection with any number of coil pipes by the simple addition or subtraction. of sections, dependent upon the exigenci'es of the particular requiirements" It is capable of a variety of uses, is easily installed as a unitary structure, permits expeditiousz'repairsto any one section or pipe, efiects a saving in initial cost by eliminating the necessity for a number of difierent sized headers, is simple in construction, may be manufactured at a reasonable cost and is efficientfor.theepnrposesintended- 1 Al'thoug in practice, I have found; that the form of invention illustrated the accompanying dmawingsand: referred to in the above description asIthe preferredjem bodinient is the most eflicient. and practical ,1 yet realizing the. conditions concurrent with. the adoptioiiflof my device. willllnecessarily vary, I desire to emphasize thatvarions minor changes in details ozt. construction; proper tion and arrangement of parts, maybe re"- sorted to within the. scope of the. appended. claims without departing from. or sacrificing otthe principles otthisinventionrl v Having thus! described my invention, what I desire protected by Letters Patent isgas set forthin thefoll-owing claiina f A header. comprising a piural'ity of relatively ad jlustable sections, the: interior walls adjacent the ends of each: section being formed with tapered seats, internal sleevesv insertable.withinthe meeting ends. ofthe se tions to bridge such oints, said sleevesbeing tapered from their centers'towamds their. ends to: engage said. complementally formed. seats, gaskets. mounted: on said. sleeves between. the meeting ends of said. sections,,closures adapt.- ed to seat Withinthe endsofthe. oppositeend sections, each closure provided wit-ha circum.- ferential' ti ange a gasket mountedl intermediate. the: flange: and the respectiize. ends. of. said.
