Application April 13, 1954, Serial No. 422,830 2 Claims. (Cl. 257-241) This invention relates to the art of refrigeration, and is more particularly directed to a method of and apparatus for refrigerating a liuid conduit, such as for example, is used for the dispensing of beer and other popular beverages, through a conduit :connected `at4 one end interiorly of the housing with the source of supply and at the other end thereof exteriorly of the housing to a dispenser faucet. Such fixtures are usually interiorly small and cramped. An object of this invention is to provide a method of and means for refrigeration of such fiuid conduits which will provide the person installing the same with ample room for making the installation in a convenient and highly effective manner. The invention is further adaptable to the provision of a refrigeration coil of a predetermined number of convolutions or of a greater number depending upon the individual requirements of a specific application at hand, and for attaining the maximum transfer of the refrigerant temperature differential to the fluid passed through the conduit. A further yadvantage of the invention is the provision of a method and apparatus which will enable a custom installation to be attained in each case so as to adapt the invention to an infinite variety of different refrigeration parts and requirements, and installation on a single conduit or on a plurality of adjacent conduits.
These and other advantageous objects, which will appear from the drawings and from the description hereinafter, are accomplished by the structure of my invention, of which an embodiment is illustrated in the drawings. It will be apparent, from a consideration of said drawings and the following description, that the invention may be embodied in other forms suggested thereby, and such other forms as come within lthe scope of the appended claims `are to be considered within the scope and purview of the instant invention.
In the drawings:
Fig. 1 is a horizontal fragmentary sectional View of an apparatus illustrating the first step in the performance of the method of this invention,
Fig. 2 is a fragmentary View similar to that of Fig. 1 but showing the reversed position of the fluid conduit pipe in the initial formation of the refrigeration coil pursuant to the invention,
Fig. 3 shows a further step of the invention wherein the coil is lfully formed pursuant to the invention and one of the T-shaped members is being removed from the fluid conduit for the removal of Athe coil therefrom,
Fig. 4 is a similar View showing the coil reassembled on the pair of T-shaped members embodying the invention disposed interiorly of the fixture housing, the T- shaped members being separated to permit the building up of the coil to a larger number of convolutions, and
Fig. 5 is an elevational View showing the application of the invention Ito a pair of adjacent fluid conduits.
As shown in the drawings, the device of the invention is adapted to be used in association with a fixture housing such vas is generally indicated by the reference character in Fig. 1, comprising external and internal insulation walls 11 and 12 having an opening 13 therethrough for reception of a fluid conduit. The liuid conduit 14, pursuant to this invention, is provided with an elongated threaded section 1S at one end thereof for normal disposition interiorly of the fixture, as indicated by the reference character 16 in Fig. 1 and is provided with a second end portion 17 which has a short threaded part 1S normally disposed exteriorly of the fixture housing 10 as shown at 19 in Fig. 1, for connection with a discharge faucet 20 or the like. A spacer ferrule 21 may be interposed between the faucet 20 and outer face 22 of the lixture housing 10. In the initial step of this invention, the fluid conduit 14 is disposed in the iixture housing 10 as shown in Figs. 2 and 3 in a position opposite to that of the normal disposition of said conduit in use (Fig. l). In the reversed position of the conduit, for the first step of this invention, it is disposed in said fixture housing 10 so that the normally internally disposed end 15 of the conduit projects from the outer face 22 of the xture 10. A pair of T-shaped members 26, 27 which are internally threaded to complement the lirst outwardly disposed threaded portion 15 of the conduit 14 (Fig. l) are disposed on said first portion 15 of the conduit as shown in Fig. 2 outwardly of the fixture housing 10, thus providing ample room for manipulation of the length of tubing to be formed into coil 36. The T- shaped members 26, 27 comprise main ring portions 28, 29 having flanges at one end thereof (30, 31) defining, with the ring portions 28, 29, shoulder portions 32, 33 (Fig. 1) for a purpose presently explained.
When the said T-shaped members 26, 27 are disposed in contact with each other as in Figs. l and 3, they will define essentially Ian elongated H in cross-section. Pursuant to the method of this invention, a continuous length of tubing 35, which may initially be of relatively flat form and of circular or other cross-section, is wound upon the members 26, 27 intermediate the flanges 30, 31 thereof so as to define an accurately formed refrigeration coil 36 (Fig. 3) comprising a plurality of convolutions, whose internal diameter is just slightly greater than the diameter of the ring portions 28, 29 of T-shaped members 26, 27 and the end convolutions of said coils will be disposed vagainst the shoulder portions 32, 33 defined by the flanges 30, 31 of said members 26, 27 (#Fig. l).
The initially flat tubing 35 may be readily bent by the worker upon the ring portions 28, 29 of the members 26, 27 disposed exteriorly of the fixture 10 as in Fig. 2 in the first step of the method of this invention to provide ample room for bending the tubing thereon. After this has been attained, the member (26 or 27) remote from the outer face 22 of fixture housing 10 is removed from the conduit 14 (as in Fig. 3) and then the coil may be slipped off the remaining T-shaped member. The conduit 14 is then re-inserted into the fixture 10 with the first threaded section 15 thereof disposed interiorly of said fixture as shown in Fig. l and then one of the T-shaped members 26, 27 is first positioned on the conduit 1.4 and threaded against the inner face 34 of the fixture 10. Coil 36 is disposed on the ring and then the second of the T-shaped members (26 and 27) may be positioned on conduit 14 and brought against its opposite member, thus completely assembling the device (Fig. l). It will be understood that the faucet 20 and the spacer ferrule 21 likewise may have been rst secured to the conduit 14 exteriorly of the fixture 10, or may be secured thereto at a later time. The T-shaped member (26 or 27) disposed on the conduit 14 lirst-that is, closer to the inner face 34 of the fixture 10, secures faucet and conduit in the housing in operative position.
The convolutions of the coil 36 may be Wound on the T-shaped members 26, 27 directly at the point of instal- 3 lation if desired pursuant to the inventori and will provide an accurate custom t therewith. The free ends 37, 38 of said coil (Fig. 4) may be connected to a system for pumping a suitable refrigerant through said coil so that there will be a direct transfer of the cooling effect of the refrigerant circulated through the coil 36 to the conduit 14 and fluid passed therethrough.
The invention may be used for forming a coil of greater length than the combined length of ring portions 28, 29 on the members 26, 27 (Fig. 4) by securing the said members 26, 27 to the uid conduit 14 with a space 39 therebetween sufficient to allow for the winding of additional convolutions of said coil 36, as indicated, for example, at 40 in Fig. 4. This may be done for the purpose of providing a greater degree of cooling surface on the conduit 14. If desired, a spacer ring 41 may be inserted intermediate the T-shaped members 26, 27 as shown in Fig. 4, in that form of the invention.
As shown in Fig. 5, the invention may be utilized for the refrigeration `of a pair of adjacent conduits 14, 14 etc.; the end convolution of the coil, which might correspond with the end 38 of said coil shown in Fig. 4, would be continued toward and around a second pair of members which correspond with the members 26, 27 on the conduit 14 as shown in Fig. 5, the free end 38' of the second coil being connected to the refrigeration circulating pump or stem, and third and further units may thus be additio'i\ formed.
Having thus d\\b\ed my invention, what I claim as new and desire to se`\1e by Letters Patent is:
1. In a refrigeration system a uid discharge conduit having an elongated threaded section at `one end to be passed through the insulated wall of a housing interiorly thereof for connection with the fluid supply source and having a second end for projection through the wall, said second end being threaded for short distance for connection with a discharge nozzle, a pair of members each comprising a cylindrical portion terminating at one end thereof in an outwardly directed flange adapted to rest in contact with the insulated wall, said members being internally threaded throughout the lengths thereof and in engagement with said elongated threaded section with the anged ends thereof disposed remote from each other so that said members define essentially a relatively long spool surrounding said threaded section and positioned in contact with the insulated wall, a length of flexible tubing wound around the cylindrical portions of said members and intermediate the flanged ends thereof so as to form a coil consisting of a plurality of convolutions, said coil being adapted for connection to a source of refrigerating fluid.
2, The apparatus of claim 1 wherein a cylindrical internally threaded spacer element is disposed between the two flanged members to form an elongated spool shaped member for supporting said coil.
