Description

Qt! 9 I J. c. GOOSMANN CONDENSER JOINT Filed April 5, 1922 A sane onion IUSTUS C. GOOSMANN, OF CHICAGO, ILLINOIS.
oonnnnsnn lromr.
Application filed April 3, 1922. Serial No. 549,270.
To all whom it may concern:
Be it known that I, J UsTUs C. GoosMANN, a citizen of the United States, residing at Chicago, in the county of'Cook and State of Illinois, have invented certain new and useful Improvements in Condenser Joints, of which the following is a specification.
This invention relates to the heat exchange apparatus and more particularly to what is known as a double tube condenser,
wherein one set of tubes is arranged to con-:
duct the fluid in one direction and a surrounding set of tubes is adapted to conduct a heating or cooling fiuid as the case may be in the opposite direction, so that heat units are exchanged from one fluid to the other during their passage through the apparatus.
While my invention is capable of a wide variety of uses, it is illustrated herein as applied to a tubular condenser adapted for use in connection with refrigerating apparatus, and it is designed primarily to provide a joint at the ends of the tubes which W111 preclude leakage from both the inner and outer tubes, and at the same time is capable of being easily assembled and also taken apart should the necessity arise.
In order to facilitate an understanding of my invention, I have illustrated in the accompanying drawing a preferred embodiment thereof, in which the single figure illustrates, partially in elevation and partially in section, a joint at one end of the condenser tubes, embodying my invention.
On the drawings only two inner and two outer tubes are shown, but it will be understood that a condenser as customarily constructed, embodies a series of such tubes arranged one above the other and such a con-v denser will have a number of joints em-f bodying my invention arranged alternately at opposite ends of the condenser to connect adjacent superposed tubes. The joints comprise primarily two header casings 5 and 6 each formed to provide a chamber 7, which chambers are connected by a ipe or tube 8, preferably cast integrally wit the header casing.
The outer condenser tubes 9 enter the open end of the casing and communicate with their respective chambers 7. Leakage ,around these tubes is prevented by a packing joint comprising a packing ring 11, preferably made of type metal or similar metallic metal, surrounding the end of the ing ring 11 by means of a plurality of draw bolts 13 extending through the member 12 and through a flange 14 on the header casing, whereby the packing is compressed around the pipe 9 to form a leak tight joint at this point without the necessity of threading the pipe.
Each header casing is provided at the inner end of the chamber 7 with a bridge wall 15 of sufiicient size to permit the introduction of the inner tube 16 therethrough. This tube extends from end to end of the condenser inside its respective outer tube 9, and as previously stated, is adapted to conduct a fluid in one direction while fluid is being conducted in the opposite direction around the inner tube through the outer tube 9.
outwardly beyond the bridge wall 15,
each header casing is provided with a recess adapted to accommodate a sleeve 17 which is threaded onto the projecting end of the tube 16, and between the inner end of this sleeve and the bridge wall there is disposed a packing ring 18. The sleeve 17 is threaded onto the tube until its outer end is substantially flush with the end of the tube and the sleeve and bridge wall are drawn together to compress the packing 18 by means of draw bolts 19 extending through a'flange 21 on the header casing and through the flange of a cap or bonnet 22 disposed over the end of the tube and sleeve. A second packing ring 23 is positioned between the bonnet and the opposed ends of the tube 16 and sleeve 17 and when the drawbolts 19 are tightened up both the' packing rings 18 and 23 will be compressed so as to provide leak-tight joints around the tube 16.
The bonnet 2 2 is adapted to receive a nipple 24 which 'is threaded at its outer end to accommodate acoupling member 25 also exteriorly threaded to engage in the flange 26 of the elbow 27. A packing ring 28 is interposed between the member 28 and the opposed surface of the elbow as shown, thereby preventing leakage at this point.
Fluid flows in one direction through the condenser in the pipes 16 connected at alternate ends of the condenser by an elbow 27, while fluid at a different temperature flows in the opposite direction around the pipes 16 through the pipes 9, the fluid being conducted through the joint from one pipe 9 to the next through the connecting portion 8. Leakage around the pipe 9 from the chamber 7 is precluded by the packing ring 11, while leakage around the pipe 16, either into the chamber 7 or to atmosphere, is precluded by the packing rings 18 and 23, respectively. Since a sliding connection only is established between the pipes 16 and 9 and the header casings, it is unnecessary to provide these pipes with right and left hand threads as is customary in some constructions, and as a result the joints may be readily assembled or may be taken down to permit the replacement of either of the pipes should the necessity arise. The joint is simple in construction, economical to manufacture, and reliable in operation, it obviates the bending of the pipes at the ends, and is ca able of eii'ecting a tight joint irrespectlve of irregularities in the lengths and diameters of the pipes, and also irrespective of whether the pipesare absolutely straight throughout their lengths or not.
It is believed that my invention and many of its inherent advantages will be understood from the foregoing without further description, and it should be manifest that the structural details are capable of considerable modification without departing from the spirit of the invention as defined in the following claims.
I claim:
1. A condenser joint, comprising an outer tube, an inner tube, a header easing having rename a leak tight connection with said outer tube at one end and provided with a bridge wall intermediate its end, a sleeve threaded onto the outer end of the inner tube, acking interposed between the inner end 0 said sleeve and said bridge wall, a bonnet arranged over the outer end of said sleeve. packing interposed between said bonnet and said sleeve, means for clamping the bonnetto the header casing,and a pipe communicating'with the inner tube through said bonnet. 2. A condenser joint, comprising a header casing, provided with a pair of chambers connected by a cross connecting pipe, outer pipes communicating with said respective chambers, inner tubes projecting through the respective chambers, sleeves threaded upon said inner tubes, bonnets clamped against said sleeves, and means for connecting said inner tubes through said bonnets.
3. A condenser joint, comprising a header casing having two parallel portions united by a cross connecting pipe, each portion being formed with an interior chamber, outer tubes communicating with the respective chambers, inner tubes projecting through said chambers, sleeves disposed upon the ends of said inner tubes, bonnets surrounding the outer ends'of said sleeves, means for clamping the bonnets to the casing, nipples communicating with said inner tubes through said bonnets, an elbow, and coupling members connecting said elbow with said respective nip les.
