'lhis invention relates to insulating material and method of making the same.
.ein object oi this invention is to provide insulating material in the form of a coms posite panel including a core ot cellular material, such as cork and the like, encased within sheet metal veneers,'and wherein the insulating material between the veneers is provided with a marginal frame to protect the lo insulation and provide means by which the composite panel may be secured in position.
Another object of the invention is to provide a method of making a composite panel ci the character referred to, wherein the metallic veneers are bonded to the insulating material under pressure, and wherein means are interposed between the metallic veneers to resist collapse ot the insulating material, and wherein said means are incorporated in 2@ the panel to form a part thereof.
@ther and further objects of the invention will more clearly appear trom the description and claims hereinafter following.
ln the drawing forming a part ot this 25 specification, Fig. 1 is a plan view of a composite panel of the typeV contemplated by the invention, having portions broken away to more clearly disclose the construction thereof. liig. 2 is a fragmentary enlarged vertical 3@ sectional view through the panel, corresponding substantially to the line 2-2 of Fig. 1. Fig. 3 is a view similar to Fig. 2,
. showing a somewhat did'erent embodiment ot the invention. And Fig. l likewise is a view similar to Fig. 2, showing still another enr bodiment of the invention.
Referring irst to Figs. l and 2, the in-1 vention includes a core of insulating material in the form of cork or any of the well known commercial insulating materials having generally similar properties. 'llhe insulating core or body 10 may be ci any thickness or shape desired, being shown as rectangular, and in the torni disclosed in Figs. 1 and 2, eachl edge of the core 10 is provided with an outwardly extending centrally disposed rib 11, said rib extending along all Jonr edges of the insulating material proper.
Disposed about the edges of the insulating 5@ body 10 is a hardwood frame comprising,r sections l2, 13, 1t, and 15, arranged in rectangu lar form, ot substantial width, and of a thiol;- ness corresponding to the-thickness ot the in sulating material lt). Each oi the trame members 12 is provided with a groove 16 for the reception oi the rib ll upon the insulating material 10, as shown in Fig. 2; glue may be placed into the groove i6 oit each ot the iframe members prior to the insertion or the rib ll formed upon the insulating material.
Extending along one dat surface ont the insulating material l0 and the encircling trame is a layer of fabric l?, such as canton llannel or similar fabric having a nap or pile, the fabric beingglued to the surface or the inu sulating core and encircling trame.
Outwardly et the fabric 12, there is provided a sheet of steel veneer 18 which is glued to the fabric.
At the opposite broad side of the panel, there is provided a sheet of fabric 19 similar to the fabric 17, and a steel veneer 20 simin lar to the veneer 18, these layers of material being secured to the body 10 of the insulating material and to the dat surface of the encircling trame. All of the laminations or layers of material are permanently secured together by the applications ot glue, and by reason of the provision ci the fabric having a nap or pile, variations in expansion and contraction ot the core l0, the trame meme bers, and the steel veneers, is compensated for, thereby preventing any possibility of severance ot the bond. The trame members 12, 13, 1li, and 15 provide means by which the panel may be secured in position, as will be understood.
Referring now to liig., 8, a core ot' insulatm ing material 21 is provided, wherein the tour edges thereof are each beveled to provide a lil-formation, indicated at 22. Ylfhe encircling trame members 23 are likewise provided with a V-shaped groove 2t, adapted for the reception of the similarly shaped portion of the insulating core 21, the trame members prererably being glued to the insulating core. Layers 25 of the fabric are provided at opposite sides oi the core and frame members, and the steel veneers 26-26 are likewise pro-1 vided, in the same manner heretofore re- @lll tions or layers being secured together by glue.
The invention also involves a process of ormin the panels.. llt is well known that insulating material carries a considerable colume ol'air cells, and it is quite. dilicult to apply metallic veneers to this class of matem rial under pressure, without collapse of the insulating material, thus rendering the same useless..
ln the present invention, the insulating material is irst prepared along its edges for the recetion of an encircling frame of hard woo, such as that heretofore described, the trame being oit the same thickness as thebody ot the insulating material. lfd ith this trame in position with respect to the insulating material, glue may be applied to the opposite sides of both, the layers of fabric, such as those' heretofore described, placed in position, additional coats of glue applied to the fabric'and the steel veneers laced in position, after which ythe assem' led composite panel may have pressure applied thereto in any desired amount necessary to eect a suitable bond between the parts, and during the pressing operation the hardwood trame re-= sists any tendency of the insulating material to collapse, said frame being thus incorporated into the panel, and serving not only as a device for preventing collapse ot the insulating material, but also to provide means by which the panel may be secured in any desired position.
While l haveherein shown and described what l consider the preferred manner of carrying out my invention, the same is merely illustrative, and ll contemplateall changes and modifications which come within the scope of the claims appended hereto..
l l l.. A method of termin a panel consisting in sandwiching a piece of insulating material between steel plates, applying pressure to said panel to bond said steel plates and insulating material together, and incorporating between said plates, as part of the panel, aspacing member capable of withstanding the bonding pressure for limiting lthe thickness to which the panel is compressed.
2.. As an article of manufacture, a composite panel comprising a pair of sheet metal A veneers spacedapart, marginal members interposed between said metallic sheets and bondedto the opposed surfaces of said metalneeaaea ,relatively incompressible material having bonding material on their surfaces, and compressing the panel and core material to the thickness determined by the blocks of relatively incompressible material.
lln witness that l claim the foregoing l have hereunto subscribed my naine this 4th day of (lctober, 1929.
