Description
July 5, 1932- c. J. SCHLAFMAN RADIATOR Filed NOV. 10, 1951 Patented July 5, 1932 V UNITED STATES CLIFFORD J. SCHLAFMAN, OF WASHINGTON, DISTRICT OF COLUMBIA RADIATOR Application filed November 10, 1931. Serial No. 574,216.
This invention relates to improvements in radiators of the type installed in 'a cabinet or housing for heating purposes by providing a construction ,enabling inexpensive manufacture and assembly and at the same time maintaining relatively high heating efficiency and rugged construction. The common type of cabinet radiator is constructed of a central core surrounded with a plurality 1c of fins applied thereto. In all cabinet radiators it is essential that intimate contact be made between the core and fins to promote highest efliciency possible. To accomplish this end many manufacturers have resorted t0 the method of pressing the fins onto the core, one after another. Obviously, this requires that exacting limitations or tolerances be placed on both the fins and core in machining. This adds greatly to the cost of manufacture. To reduce the cost of making the radiators I propose to attach the fins to side plates by spot-welding them in spaced relation and to bring the fins into intimate contact with the core by means of bolts extending thru side plates. This method eliminates the close fitting required for pressing the fins onto the core and provides a radiator of inexpensive construction and relatively high efliciency.
.30 The several features will be brought out more in detail in connection with the drawing illustrating a preferable embodiment of the invention.
Figure 1 is an elevation of a radiator unit.
.35 Figure 2 is a cross section of radiator unit taken on line 22 of Figure 1.
Figure 3 is a perspective view of a portion of one section showing the fins mounted on side plate, and
Figure 4 is a perspective view of one fin.
In disclosing the subject matter of the invention I contemplate that the radiator structure may be adapted for use wherever steam or hot water or other fluid is used as a medium for heating.
In Figure 1 is shown the application of the invention. The radiator unit being connected to supply pipe 3 and return pipe 4:,
a valve 5 being located in the supply pipe 3 at the usual position. The heating element within the cabinet 6 comprises a core 7 preferably of a die cast metal construction of shape shown in Figure 1 and Figure 2. Mounted on the core are two sections of fins as shown in Figure 2. Each section, as shown in Figure 3, is composed of a plurality of fins 8 spot-welded to side plate 9 in spaced relation. Each fin, Figure 4, has a central aperture therein conforming substantially to one half of the sectional contour of core 7. As shown, two sections of fins are mounted onto core simultaneously by means of bolts 10, 1O extensible thru side plates 9, 9, clearance being maintained between the fins of opposing sections, so that the bolts may be drawn up 5 tightly. The efficiency of a radiator of this type depends upon the establishment of an intimate contact between the core and fins and in Figure 2 it can be seen that by means of bolts 10, 10, a pressure of desired intensity can be applied to the side plates, of both sections, so that the fins are forced into intimate contact with the core.
Thus the radiator described will institute a savings in that the radiator can be quickly assembled by sections eliminating to a large eXtent involved and laborious assembly costs and without sacrificing the heating efficiency of the radiator. As can be seen the construction of this radiator places no exacting limi-"so tations upon the dimensions of the core or fins and therefore a radiator of ample ruggedness and strength can be made to meet the demands and requirements of service.
Various modifications of the apparatus shown and described may be made by those skilled in the art without departure from the invention as defined in the following claim:
What I claim is:
In a radiator, of the class described, comprising a vertically elongated core flanked,
on either side,
by a plurality of fins united directly to side plates, in spaced relation, said fins having central apertures therein conform- 5 ing substantially to one half of the crosssectional contour of said core, and a clamping means to assemble core and fins into intimate contact.
In testimony whereof I have affixed my signature to this specification.

SGHLAFMAN.
