'lhis invention relates to coils designedto afford a zig-zag flow of a fluid medium there-- through. In its chief intended application, the coil of my presentinvention is designed for service in cooling and refrigerating apparatus, either for the passage of a cooling medium, such as cold water or brine, therethrough, or for the flow-of a 4refrigerating` gas, such as ammonia; but it may also be used as a radiator of heat, if desired, by connecting it to a source of steam or hot water.
Coils of this character formed from a single length of pipe bent into zig-zag form are known; but such one-piece coils are expensive to make and impractical except from small diameter pipes of comparatively soft and flexible metal. The object of the present invention is to provide a built-up or assembled coil structure that can readily and chea ly be manufactured from ipes of any'desired)l bore, that shall ybe rugged), strong and fluid-tight, and that can be easil Y and quickly adjusted to stop a leak, shoul ayleak develop at any An approved physical embodiment of the inventi'on'is illustrated in the accompanying drawings, vin which- Fig. 1 is a side elevationof the assembled coil;
Fig. 2 is an inner face elevation of one' of the hollow headers;
Fig. 3 is a longitudinal section of the tapped header taken on line 3--3 of Fig. 4; Fig. 4c is a longitudinal section of the tapped header taken on line 4-4 of Fig. 3; Fig. 5 is a longitudinal section of the blank header taken on line 5 5 of Fig. 6;
Fig. 6 is a longitudinal section of the blank header taken on line 6--6 of Fig. 5; t
, Fig. 7 is a sectional detail showing one of the packed joints between the pipes and h'eaders.
Referring to the drawings, 10 designates what I term the tapped header and 11 the blank header. The two headers are hollow f cast metal structures and areidentical except for a difference in the location of their transholes 12 and 13 in the lower and upper ends of the headerl() for Athe reception of inflow and outflow pipes 111 and 15, respectively.
cling and spaced from each hole is an annular groove 16. The tapped lheader 10 is, in the instance shown, formed with three spaced' thin transverse partitions 17,18 and 19 (Fig. y 4), the end partitions 17 and 19 being centrally enlarged and cored forming hollowl bosses \ 17 and 19 to accommodate a pair of tie rods hereinafter described. The blank header 11 is formed with a pair of thin transverse partitions 2O and 21 that are offset relatively to the three partitions 17, 18 and 19 of the tapped-header. Extending across the enducompartments of the blank header 11 are hollow integral bosses 22 also designed for the passage of the tie rods. A
23 designates each of a group of straight pipe sections that extend between the inner faces of the hea/ ders 10 and 11. In assemblingw two'headers 10 and 11 are placed in opposed relation, and the ends of the pipes 23 are fitted into'the annular grooves 16 of the two headers with theirv ends abutting against gaskets 24 seated in said grooves. Tie rods 25 are then-passed through the hollow bosses 1 7', 19'., of header 10 and the hollow bosses'22 of header 11, and nuts 26 on the threaded ends of said tie rods are turned up to tightly clam the headers on the pipesf-.and force the en s 'as Y ofy the `latter into leak'proof engagement or in the same manner in reverse direction,
if the direction of flow be reversed.
. 'Ihe described construction affords a strong, substantial and rugged coil structure` that is easily andi cheaply made and assembled from header castings and straight pipe secf tions of uniform length, 'its leak-proof character being most cheaply and `conveniently secured by the use of annular. grooves receiving the ends of the pipes and gaskets in `said dit grooves. By reason of the fact that the in- 7 tegral hollow bosses 17', 19 and 22 extend entirely across the flowpassages of the head ers, the structure is rendered entirely leakproof at the tie-rod connections without requiring the use of any packings at said connections, and this construction also reduces the height of a coil of given capacity as compared with a like coil having tie-rods located outside the pipe area of the coil. Should w leaks at any time develop at the joints, they are readily'cured by simply tightening up the nuts 26 on the tie rods 25.
I claimf I l. A coil of the character described, corn- 15 prising opposed Vertical hollow headers formed with horizontally opposed holes in their respective inner faces, parallel pipes extending between said headers and at their ends registering with said holes, means providing duid-tight joints between said pipes and headers, integral transverse partitions in said headers dividing the latter into flow chambers connecting the ends of adjacent pipes, said partitions being so located as to cause a zigzag How of fluid through adjacent pipes in opposite directions, integral hollow bosses extending entirely across the flow pas, sages of the headers, the bosses in one of said headers being formed as integral parts of partitions of said header, andtie-rods extending between said headers and through said hollow bosses; one of said headers being :formed with lower and upper lateral open- 35 ings registering with the lower and upperpipes of the coil for connection of inflow and outflow pipes thereto.
