WALL INSULATION Application led February 11, 1929. Serial No. 339,075.

This invention relates to wall insulation, and includes walls, floors, roofs, and partitions, etc. of particularly wooden buildings.

. The object of my invention is the provision of simple and eiiiclent means for greatly minimizing the danger of fires, extreme cold, minimizing the use of fuel, and in hot weather "or tropical climates, tendin .kee `the building cool, by exclu ing heat. lo Vlith the vforegoing and other objects inv view, my invention comprises certain novel constructions, combinations andl arrangements of parts as will be hereinafter fully described, illustrated inthe accompanying drawings, and more particularly pointed out in the'appended claims. In the drawings:

Figure 1 is a vertical, transverse sectional view of a wall structure, constructed in ac-v cordance with the present invention, which illustrates the principle as it appears in either a wall, partition, `floor, or roof parallel to the studs, joists or rafters.

Figure 2 is a horizontal transverse sectional view taken through Figure 1.

Figure 3 is a fragmentary, horizontal scctional view, showing the edge of the insulating sheet with la tapering edge or tongue for producing a very tight joint against the con- 3o tact wood member vsuch asa stud, while AIn Figure 4, a similar view is shown of a soft thick edge formed` on a sheet.

Figure `5 is a diagram showing the sheet or board as used in connection with a large or wide'stud, joist or rafter.

Figure 6 is a diagram of a standard sheet or board used .with an ordinary rafter. studl or joist.

Figure 7 is a diagram vshowing the sheet or board used in connection with a smaller stud, joist or rafter. y

Figure 8 shows a plurality of sheets with overlapping edges, .used for larger spaces, occurring betweencontiguous joists or studs or rafters.

Figure 9 is a vertical, sectional View of a wall structure, showing two sheets in the same .space with nailing blocks for securing the sheetsin position. 1

greatly to Figures 10 and 11 are diagrams showing modifications of the sheets.

Figure 12 is a diagram, partly in section,

showing a quantity of bent or corrugated sheets or boards, crated for shipping.

Referring to the drawings by numerals, l

designates the outer unit of .the building,

whether it be the sheathing, clapboard or roof, against which are the studs, joists or A rafters 2, with the inner finished` surface element 3, such as the wall of the room or the ceiling or the like.

The sheet or board 4 is of any heat insulating material of suiiicient thickness and rigid- `ity to hold its preferred shape, but with suiiicient springiness to allow it to bend from the position indicated by dotted line 6 to the fixed position at 6, as a result of pressure rom the application of finishing material constituting the inner wall or face 3. The corrugated or irregular sheets or boards are pressed into place between studs, joists or rafters 2, unti point 5 comes in contact with outer boarding or sub-ilooring, as 1, and is secured to 1 with nails or staples 5".

The boardl or sheet 4 will be manufactured in strips slightly larger than the customary space between studs with the deformable edges 7 either tapered to a point, as shown at 7, Fig. 3, or formed with a soft and thick or bushy edge, as shown by dotted line 7", so that the original sheet, as shown by said dotted lines, will be depressed by pressure, required to force the sheets between studs into the fixed position, as shown by solid lines 7, inthe two embodiments, Figs. 3 and 4, thus insuring ti ht contact to the studs, joists or rafters. Fr smaller spaces between studs, sheets may be cut, or for larger spaces, two sheets or more may be used with lapping edges, as shown in Figure 8.

In Figure 6, the diagram shows the shape of preferred sheet, while'in Fi re 5, the diagram shows the position or s ape taken by the sheet when used between larger studs,

Joists or rafters, while in Figure 7, the diagram shows `the sheet bent into a smaller space, as when used in conjunction with smaller studs.

Figure 9 shows possible application of two blocks 8, forsecuring the second sheet at 2 .A I( A sheets 4 and 4 in the same space with nailing In Figures and 11, modified forms of the sheet are shown; in Figure 11, I have shown the sheet ashaving less surface contact withboardin 1, and inside finish 3, thus 1. giving better insu ating results.

" In Figure 12, I have Ishown a pluralityof corrugated sheets or boards 9 crated fors ping; 10 are blocks of the same depth as t e pitch of the corrugations, and'11 are strips to' i hold blocks 10 in place, thus providing a compact, secure and economical` methodof packing for shipping. The insulating eiiect will be produced both by the quality vof insulation in the sheet itself and'by dividing the whole (including the space between the outer and inner wall units) stud spaces into tight, horizontal dead airspaces. B dividing the whole flue-like spaces between t e studs, ]oists or rafters into a-numberof cells at right angles to the length of studs, joists or rafters, fire would .have to burn through from one space to the next in order to spread in the spaces, and would tend to smother itself by exhausting oxygen and generating carbon dioxide. This lire stopping quality would be increased by impregnating sh'eets with ire resisting chemicals.

This sheet or board can be manufactured in several'different widths anddifferent size corrugations to fit all customary spaces between three inch to six inch studs and 'six inch edges to twelve inch rafters or joists. Odd shapes r and spaces may be readily fitted. i

The sheet or board can be apphed with a edges actas clamps or binders, whereby an claims.

While I have described the preferred ein` bodiments of my invention and illustrated.

the same in the accompanying drawings, certarn minor changes or alterations may appear to one skilled in the art to which this inven-4 tion relatesy during the extensive manufacture of the same, and I, therefore, reserve the right to make such changrles or alterations as shall fairly fall within t e scope of the appended What I claim is': 1. As a new article `of manufacture, an -insulating sheet having partitioning-engaging edges varying in shape from the body of said sheet, and said partitioning-engaging edges -being capable of bending when crowded against' partitioning elements for entirel holding said sheetin place.

2.- As a new article of manufacture, an insulating sheet provided' with ta ering flexible opposite edges adapted to be ent against partitioning elements for entirelyz holding said sheet in position. l l i' 3 .'An insulating sheet provided with deformable edges, and said deformable edges adapted to cause a gripping action on parti= tioning means when saivd sheet is therebetween. lIn testimony signature.
