Patented Nov. 19, 1935 UNITED STATES PATENT OFFICE INSULATING PANEL Application December 20, 1932, Serial No. 648,134
10 Claims.
This invention relates to insulating panels of the general type disclosed in U. S. Letters Patent No. 1,652,055, issued to Walter M. Schwartz under date of December 6, 1927.
The principal object of the present invention is to construct a panel in a manner to minimize the conductivity of heat from one of the metal faces of the panel to another substantially parallel metal face thereof, by reducing the total extent of the direct metal contacts and connections between the two faces of the panel as much as possible without sacrificing stability and rigid.- ity of the panel unit.
The construction of a panel made in accordance with the principles of the present invention will be more fully disclosed hereinafter, reference being had to the accompanying drawing, of which:
Fig. l is a, face view of one side of the panel;
Fig. 2 is an edge view of the panel shown in Fig. 1; and
Fig. 3 is a fragmentary transverse sectional view taken on the line 3--3, Fig. l, drawn to an enlarged scale.
The panel comprises a pan section I and a cover section 2. The pan section I is composed of a sheet or plate of metal 3, forming one face of the panel. The marginal edges of the sheet 3 are bent substantially at right angles to the plane of the main central or body portion of the sheet to form a flange 4 which constitutes the marginal edge wall of the panel.
The immediate outer edge of the flange 4 is bent at right angles to the flange 4 and constitutes a supplementary marginal flange 5 which is disposed in a plane substantially parallel to the plane of the main central body portion of the sheet 3.
The supplementary flange 5 is cut away at spaced intervals, as illustrated at B in Fig. 1, to provide a plurality of ears or lugs l disposed in laterally spaced relation to each other, completely around the marginal edge of the pan section I of the panel.
From each of the ears 1 extends a diminutive protuberance 8 which is pressed from the ear I, or otherwise formed thereon, to extend beyond the plane of the flange 5 in a direction away from the facing sheet 3 of the panel.
The cover section 2 of the panel comprises a main body sheet or plate 9 having a marginal flange 58 extending completely around the panel, substantially at right angles to the plane of the sheet 9 and substantially parallel to, and spaced from, the edge wall 4 of the pan section I of the panel.
The facing sheet 9 of the cover section 2 rests directly on the protuberances 8, whereby the fac-- ing sheet 9 of the cover section 2 is spaced a predetermined distance away from the flange 5 of the pan section l and from the parallel edge of the edge wall 4, as clearly illustrated at H 5 in Fig, 3 of the drawing.
The only direct metal contacts between the pan section I and the cover section 2 of the panel are those afforded by the diminutive areas of the projecting faces of the plurality of relatively 1Q spaced protuberances 8 which engage or contact with corresponding diminutive areas of the facing sheet 9.
The space within the panel as defined by the opposite face walls 3 and 9 and the marginal edge 15 wall 4 thereof is filled with any suitable insulating material, such as mineral wool or corrugated asbestos sheets illustrated at l2 in Fig. 3.
In the present instance the pan section I and cover section 2 are permanently secured together, 20 to provide a rigid panel unit, by spot weldings 25, 25 respectively confined solely to and within the diminutive areas of contact between the outer faces of the protuberances 8 and the corresponding areas of the sheet 9 lying in direct contact 25 therewith.
For purposes of assembling a number of the panel units to form a continuous wall, such as the side walls or the roof of a drier, a suitable heat-insulating gasket element 24 is provided in the marginal groove 23 formed between the marginal edge wall or flange 4 of the pan section I and the parallel flange ll] of the cover section 2 of the panel.
