INSULATING PANEL FOR BUILDING WALLS Filed April 28, 1958 l5 s E .5. 7 3- ATTORNEY.

Patented July 9, 1940 UNITED STATES PATENT .OFFlCE 4 Claims.

blocks for the interior or the exterior faces of building walls, and the principal object is to provide a block formed of an inexpensive metallic container and an insulating element secured therein which may be held in courses as with various building blocks or brick, or in the manner of tile on an interior wall surface, in either of which the metallic casing is exposed to view.

It is further an object and feature of the invention to provide a metallic casing of a rectangular form having side walls and a bottom, the 0pposite face being open to receive an insulating member which may be secured therein in any approved manner as by cementing the same in place or by forming the casing subsequent to the placement of the insulating material in a manner to secure the same therein.

It is further a feature and object of the invention to provide an insulating block or tile such as above described in which the side walls of the metallic container are provided with projections to align with similar projections of the adjacent block or tile and thus providing a uniform space between adjacent blocks for a plastic or cementitious material and in which arrangement the projections are so positioned that a block will readily be erected in association with a half size block and a quarter size block with the projections of the major size block fitting the projections on the blocks of the other faces.

These and various other objects and novel features of the invention are hereinafter more fully described and claimed, and the preferred form of .a block or tile embodying my invention isshown in the accompanying drawing in which- Fig. 1 is a plan view of the outer face of a block or tile in association with a second block or tile, the drawing being partly broken away to show the inner insulating element.

Fig. 2 is an edge elevation thereof.

This invention relates to insulating panels or Fig. 9 is a perspective View showing my improved block or tile applied directly to the sheathmg of a wall element.

The block may be made of various sizes and of various thlcknesses but, due to the insulating character of the block, need not be very thick from face to face andmay be quite thin where uselcll as a t1le for mounting on the interior of a wa In its preferred form, the block consists of a 10 rectangular metal shell as indicated at I and there shown as square in form. As will be observed from Fig. 2 particularly, the shell i has a metal bottom 2 and side walls 3 and an open face opposite the wall 2. In this pan-like form of shell is board. The insulating member 4 is secured in the shell and may be secured in several ways as for instance, by coating the inner face of the shell and /or the edges and one face of the insulating element with pitch which becomes subsequently very hard and the manner block or panel to a wall is preferably by means of cement applied to the outer exposed face of the msulator member 4 as is indicated at 5 in Figs. 1 to 7 inclusive. The insulating element may also be secured in place as 8 or portions of the edge of the side walls of the shell I over the peripheral edge of the insulating member as shown in Figs. 5 and 7. For securing the panel or block in position, a cementitious material may be applied to the exposed face of the 35 insulating element in any approved manner whereby the same may be secured to a surface, as for instance the sheathing I of the wall,'shown in Fig. 2.

A feature of the invention is involved in the 40 provision of the outstanding lugs about the periphery of the shell. These lugs may be pressed out in forming the shell as is indicated in Figs. 1 and 5 or may be provided, as indicated at M,

by means of a metal lug secured, as by welding, to 45 mitted to a grinding operation to true the outer 50 faces of the lug and to provide a block of a definite overall size which wouldbe a standard size or multiples or divisions of a standard size so that the blocks, when laid, are spaced accurately to provide uniform interstices between the blocks 5 of attachment of the by inturning an edge 30 and thus do not require odd sizes of blocks in the formation of a wall other than the required multiplcs or divisions of the block. This will be more fully understood from Figs. 8 where is shown a major size block at H having the lugs 9, ID or other form so spaced about the periphery as to match lugs of blocks of a half size indicated at l2 and a quarter size as indicated at I3, I3. It will be observed from this view that, by properly spacing the lugs on a major size block and on the divisional sizes, the lugs of several adjacent sizes of the blocks align with the lugs of the respective lugs of contiguous blocks or panels. Thus, by forming the shell with its projecting lugs accurately surfaced to provide an overall length and width of block, a wall may be uniformly laid to fit any length or height of wall surface that is a multiple of the major block size.

The lugs have three functions-namely, to determine the overall dimension; to space the blocks or panels a predetermined distance apart to provide for a uniform spacing of the blocks in which a plastic or cementitious material may be forced, and to sustain such plastic from sagging, particularly in vertical interstices between blocks which sometimes under a hot sun may tend to soften and sag.

As previously stated, the faces of the lugs are to be ground to provide a block of a standard overall size and inv divisions or multiples of one of the sizes. For the best results, the faces of the lugs are to be ground to a true plane surface, the lugs on one side edge being at a right angle to the adjacent side edges and parallel with the plane surfaces of the opposite parallel side of the blocln This insures not only the proper spacing of the laid blocks but tends to position the series of blocks with their faces in substantially the same plane or so nearly so as not to be readily observed. An essential characteristic of the invention is therefore involved in thus providing the spaced lugs which, in contiguous blocks, are in surface contact to thereby effect a true parallelism of the surfaces of the outer faces of the panels or blocks and any inaccuracies in the wall surface to which they are to be applied may be compensated for by the use of an adhesive in greater. or less quantity on the inner faces of the panels.

The blocks or panels are applied to a wall surface by placing a sufficient amount of cementitious material at various points on the surface of the insulating element sufficient to securely hold the panel or tile in place on asupporting surface as, for instance, the sheathing I of Fig. 9.

The outer face of the metal panel may be embossed if desired, as indicated at M in Fig. 8 which is illustrative only of one form of embossing, it being understood thatvarious designs may be provided by embossing the sheet metal, and it is to be observed that it is the metal surface that is exposed to atmosphere, either of a room or outside atmosphereand the metal of which the shell is made may be of any desired composition or character as, for instance, stainless steel, copper, brass orother composition and even may be treated to provide a color effect The drawing has shown the device as beingof rectangular form and, this is the usual form but in all wall surfaceswhere the block may be applied, there are portions of such surface other than rectangular, and it is to be understood that changes in form of the block to fit a particular area are within the spirit and scope of this invention, a feature of which is in the provision" of lugs on peripheral wall of the block to engage lugs of an adjacent block.

From the foregoing description, it is believed evident that the various objects and features of the invention are attained by the structure described; that the block is of an inexpensive character, being formed of very light gauge metal which becomes a retainer for an insulating element but serves to protect such element from weather conditions and may furnish either a dull or a bright surface as may be desired in various types of structures and for various locations on the interior walls of a building, and it is also to be understood that various changes may be made in the form of the structure (which may be other than rectangular as shown) without departing from the spirit and scope of the invention as set forth in the appended claims.

Having thus fully described my invention, its

utility and mode of operation, what I claim and desire to secure by Letters Patent of the United States is v 1.
