Other objects and advantages will be apparent from'the;following,description of an embodiment of the -invention, and I will here inafter particularly point out the novel features in claims. 7

In the accompanying drawing:

Fig. 1 is a front elevation of one of the units or sections constructed in accordance with the invention.

Fig. 2 is a transverse section of the same taken substantially along the line 22 of Fig. 1.

Fig. 3 is a fragmentary transverse section of the same taken substantially along the line 33 of Fig. 1, and p Fig. 4 is a perspective of the bushing.

In the illustrated embodiment of the invention, each unit or section comprises a tubular metal shell 1 which is formed around and upon a metal bushing 2. The bushing is provided with lateral flanges 3 having therein apertures 4 that are parallel to the main passage of the bushing. The shell is secured to the flanges around the apertures 4 so that these apertures will not be in communi cation with the interior of the shell. The

shell is preferably formed upon the bushing by-electro-deposition of metal such as copper. For example, the bushing may be set into a frame of lead or other metal or alloy fusing at a low temperature, which frame has a shape and size corresponding to the desired interior of the shell. This frame is then plated with copper by the use of a current of electricity and a suitable electrolyte in which the metal frame and bushing are im-- mersed. After the coating'of copper has reached the desired thickness, the coated cl ti pthe frame is removed and heated to'fu'se' out the metal frame. and leavethe copper'she'll seur l 'attached tth bushing.

T

Screw nipples 8 may be used to connect the adjacent sections, as illustrated in Fig. 3, by threading the same into the adjacent ends of two abutting bushings. Since the threads sage foffthe biishinggfwith the interior-of the;

at the opposite ends of each bushing are opposite in direction, rotation of an interposed threaded nipple in one direction will,

the passages 5 and interlock therewith.

When the coupling has been completed the tools may then be withdrawn. The bolts 7 may also be passed through the aligned apertures 4 of the bushings to prevent twisting or distortion of the shell while the nipples are being threaded into the bushings. The bolts then subsequently assist in coupling the sections so as to prevent ro-, tation of any section upon a nipple or relatively to the other sections.

With this construction of radiator sections and assembled radiator, a comparatively thin shell may be employed, and the bushings will take up all twisting or distorting stresses and prevent their transmission to the shell. The conduits of the bushings may be connected by either the nipples or gaskets,

and communication between the connected bushings and the interiors of the shells is effected through the passages 5.

It will be understood that various changes may be made by those skilled in the art in the details and arrangements of parts of the embodiment described herein and illustrated for the purpose of explaining the nature of the invention, Within the scope of the appended claims.

I claim:

1. A radiator section comprising a shell, a coupling bushing to which the shell is secured, said bushing having apertured lateral extensions to which the shell is firmly secured around the apertures so as to form apertures through the sections offset from the bushing aperture and closed from the interior chamber of the shell, whereby the sections can be secured firmly together at the bushings either temporarily or permanently.

2. A radiator section comprising a bushing with a threaded aperture and apertured lateral extensions, and a tubular shell formed upon the bushing including the extensions and around the apertures, whereby when the sections are to be connected through coupling conduits threaded into adjacent ends of the threaded apertures of the bushings, rods may be passed through the apertures of the extensions to prevent twist ing and distortion of the shell.

3. A radiator section comprising a bushing with its inner peripheral surface oppositely threaded from each end and having an apertured laterally disposed flange, a tubular shell in which the bushing is secured with the flange aperture forming a passage through the shell from face to face, through which may be passed a bolt for coupling to gether a plurality of sections abutting face to face, the bushing having therein a passage connecting its inner peripheral surface with the interior of the tubular shell.

4. A radiator section comprising a bushing having a main passage and one or more auxiliary passages disposed parallel to and laterally of the main passage, a tubular shell of metal electro-deposited around and upon the bushing, whereby the main passage serves as a connecting conduit between coupled sections and the auxiliary passages permit the passage of coupling rods through abutting sections.

In testimony whereof I have hereunto set my hand.
