HAS A 7'7'0RNEV Patented June 27, 1950 RADIATOR EN CLOSURE Thomas Marini, Camden; N. L, assignor to Marver Metal: Mg.. 00., acorporation of Dela ware Application November 1, 1946, Scrial'N'o. 70711221 8;Glaims.

The present application is a; continuation in part of my prior application filed October 1 1, 1946, Serial No. 702,737, relating to improvements in a radiator enclosure.

The invention relates to radiator enclosures or covers which completely house the radiator, and more particularly to an enclosure of the knockdown type.

Because of the bulk or a radiator enclosure, it is common practice to construct it of parts readily assembled. This construction effects economies in packaging, storage-space,- shipment, etc. However, it has certain disadvantages in that at the place of installation, unskilled. labor is often employed whichfr quently introduces an assembly problem, particularly if tools are required.

It is an object of the present invention-to provide a radiatorenclosure of theknock-downtype, characterized by simplicity of construction, ease of assembly with respect to time and tools required, etc.

Another object is the provision of aradiator enclosurehavingend panelsprooi'ded with means for interlocking'with the front and rear walls, whereby interIocki-ng connections are formed between the wall" components and the end panels upon assembly of the enclosure.

Another object of the invention is the provision of a radiator" enclbsureso constructed that the component parts thereof are rigidly secured to..- gether by interlocking joints completed upon the assembly of said parts, which assembly maybe made withouttheuse of tools.

Another object of the invention isthe provision of a radiator enclosure having end panels, each of which is provided with a rounded corner and an angular corner, the rounded corner being adapted to accommodate a bracket member having means for clamping the front" wall to the bracket, and the angular corner having means adapted to engage-clampingmeans onthe rear wall, said clamping'means becoming effective by forming interlockingjoi'nts when the component parts of the enclosure are assembled.

A special object of the inventionis the provision of a bracket device that may be formed as a unit by a die operation and pro-fabricated" as part of an end sectionadapted to formaninterlocking joint with a, wall section by-merely'bringing the interlocking portions into engagement with a snap movement.

Other objects and advantages of the invention will become apparent'as the description proceeds;

For-a full and morecomplete understandingof 2! the invention, reference may be -had to the-fol"- lowi ng description and accompanying drawings, wherein:

The radiator: enclosure herein contemplated may be formed 01? separate parts made of sheet steel orother suitable material The enclosure comprises a topd, a front and'rear'wall z and 3, respectively; and end'panels tand 5 These-parts are normally disassembled to save storage and shipping space.

The. bracket-.member 113; is. designed to fitrinto; the rounded. corners H; and: I52: of-..the end; panels 4 and.5;,andz-theangularityof: the side portions l5; and. t6; withrespect "to ztheibndyzpor tion is. roughly determinea the. spacing of the bracket from saidicorners. That istosay; the less obtuse the angle of displacementof' the? side portions l5 and: It to: the'body section. I54; the closer the bracket may-be placed with; respect to the rounded corners; and vice versa, the more obtuse this angle, the fizrther away will the bracket be located. Therefore, the geometry and dimensions of the bracket elements are important factors in designing the bracket from the standpoint of securing optimum results.

It will be noted that the body section M of the bracket 13 may be regarded as a strut member joining the side portions l5 and 16. The side portion I6 is of greater length than the side por tion [5, inasmuch as the edge thereof is provided with a flange I! reversely bent upon itself to form a groove l8, which arrangement constitutes a clip adapted to receive the flange IQ of the pieces 9 and In of the front wall 2.

It will be seen that theconstruction of the bracket l3 readily lends itself. to a die stamping operation, and the bracket may be suitably welded to the end panels as a pre-fabricating step. From that standpoint, no assembly of the bracket is required as part of the installation of the radiator enclosure. The location of the brackets I3 within the rounded corners of the several end panels is important in that the bracket is so mounted that the edge of the flange 29, extending laterally from the front wall 2, functions as This will of the panels 4 and 5, thus providing an extension which. produces an over-lapping of the adjacent edges when the flange IQ of the front wall is inserted into the groove I8 of the clip 20. As an expedient to insure a snug fit of the flange 19 within the clip 20, the free or projecting edges of the panels are each provided with a rolledover portion forming a bead which is designed to function as a pivotal point in holding the front wall Zparallel to the rear wall 3 when the front; wall is locked into engagement with the clips 20.

A somewhatsimilar clip construction for interlocking the rear wall 3 to the inner ends of panels 4 and 5, may take the form of continuing the body portion of said panels rearwardly and forming an angular corner by bending the end of the body portion at substantially right angle, thus forming a rear side wall 2| to the several panels. A flange 22 is formed at right angle to the side wall 2| of each of said panels, by bending the edge of said wall inwardly. The flange 22 is preferably bent at an angle slightly obtuse to the face of the rear wall 3. A bracket element 23, consisting of a piece of sheet metal, and having one of its edges reversely bent upon itself to form a groove24, constitutes a-clip 25, similar to the clip 20. It will be noted that the inturned face of the bracket 23 and the flange 22 are inclined to form complementary angles, which is a simple expedient for insuring a tight sliding engagement between the roove 24 and the flange 22.

The bracket 23 may be spot welded to the rear wall3 and relatively positioned thereon so that when said wall is secured in place, by inserting the flanges 22 into the channelway of the clip 25, there will not only be a tight or interlocking connection therebetween, but said bracket also will function as a stop for engaging an inwardly formed flange 26, (see Fig. 3) whereby the wall 3 will be supported at the same height from the floor as that of the front wall 2.

Referring particularly to Figures 2 and 5, it will be noted that the rounded corners l l and I2 of the end panels 4 and 5 are each provided with a flanged rest plate 21. The plates 21 project outwardly from said corners and are shaped to permit the fitting of the edge flange portion :28 of the top I thereover, when the top is in place. By having the rest plates 23 project over the rounded corner of the end panels, said plates constitute a support for the top 1. As is customary, the top I may have a filler of sheet asbestos (not shown) held in place by any suitable retaining means, such as lugs or clipsa In the assembly of the radiator enclosure, one of the end panels may be set up vertically and an end of the wall section 2 locked onto the bracket 13 by inserting the flange [9 into engagement with the groove l8. This may be effected by slightly twisting or tilting the wall 2 inwardly, as shown by the dotted lines in Figure 4. Upon insertion of the flange l9 into the groove N3, the wall 2 is moved forwardly and the flange thus becomes tightly clamped in the clip 29, forming an interlocking joint. The outward movement of the wall 2'ifis limited by its engagement with the beaded edge 39. In a similar manner, the other end panel is locked to the opposite end of the wall 2. With the two end panels now hinged to the front wall 2 by interlocking engagement therewith, the rear panel 3 may be attached in place.

-With the front wall 2 locked in place, it is a simple operation to insert the flange 22 into the clip 25, by merely holding the rear wall 3 over said clip so that the flange 22 may be inserted in the groove 24, and then pushing downwardly on the rear wall 3, until the flange 26 engages the top edge of the bracket 23. The channelways provided by the oppositely disposed clips 25 will thus receive the flanges '22 and rigidly lock the wall 3 into position. v I

From the foregoing description, it will be appreciated that the assembly of the radiator enclosure may be made without the use of tools. Due to the simplicity of construction, no skill whatever is required on the part of the person making the assembly, and it is obvious that it may be done within a very short time.

While certain preferred embodiments of the invention are hereinbefore set forth, it is to be clearly understood that the invention is not to be limited to the exact construction illustrated and described because various modifications of the details may be provided in putting the invention into practice within the purview of the appended claims.
