INSULATING MATERIAL FOR BUILDING AND SIMILAR PURPOSES Filed Aug. 29. 1929 INVENTOR S om BY /zls ATTORNEYS Patented Aug. 1932 UNITED STATES PATENT OFFICE CHARLES A. UPSON, OF LOCKIORT, NEW YORK, ASSIGNOR TO THE UPSON COMPANY, E LOCXPOBT, NEW YORK, A CORPORATION 0F NEW YORK INSULATING ILA'IEBIALl FOR BUILDING AND SIMILAR PURPOSES Application led August 29, 1929. Serial No. 389,301'.

My present invention relates to building materials and more particularly to a prepared building material made ready to apply as an insulation for walls, ceilings, and floors, land it has for its object to prvide an improved article of this naturewhich will lend itself in a peculiarly advantageous manner to the manipulations of the user in applying it, and at the same time provide an improved insulation medium particularly against the entrance or escape of heat and cold.

,T To these and other ends the invention resides in certain improvements and combina- .tions of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the' end of the specification.

In the drawing:

Fig. 1 is a fragmentary longitudinal central sectional view through a formin machine illustrating the manner in whic my improved insulating material is produced;

Fig. 2 is an enlarged transverse sectional view through a strip of the material in its normal condition;

Fig. 3 is a view similar to Fig. 2 showing the strip bent transversely to conform to its intended position between the oists of a ceiling or floor or between the stu ding strips of so a wall;

Fig. 4 is a further fragmentary sectional view showing the material of my invention bent and secured in place between 'thestud ding strips of a wall, and Fig. 5 is a similar view showing two companion strips of the material similarly laced in a dilerent manner between a plura 'ty of adjacent studding strips.

Similar reference numerals throughout the several views indicate the same parts.

Referring first to Fig. 2 of the. drawing,

there is there shown, as before stated, a transf verse section of a strip of insulating material constructed in accordance with and illustrating one embodimentof my invention. It comprises a filler or interior body portion 1 zoi? a flocculent fibrous material such as hair, cotton or an appropriate one of the substances usually employed in the making of 5o carpet linings and building materials of this general nature. I prefer to employ a mixture of short cotton ibers or cotton waste and jute, but this selection is immaterial to the objects of the present invention.

The interior body is faced and coniined on both sides by liners 2l and 3 which have considerable tensile strength and may bel composed, and preferablyare composed of paper. The central portion of the strip is relatively thick and fluffy but the longitudinal edge portions indicated generally at 4 are relatively thin or compressed as clearly shown in Fig. 2. This thin edge may be produced by using less of theiiller stock at these points or by compacting the stock or both. I prefer, in any event, to compact the filler stock at the edges by compressing and sewing the liners 2 and 3 together in this region as indicated at 5. I further refer to first confine the said longitudinal e ges 4 of the bat between paper or similar strips 6 arranged on opposite sides and through which the line of stitching 5 is made. The liners 2 and 3 are later pasted thereon with an adhesive that secures the stitches to the strips 6 and prevents the bat from later expanding at these edge portions. There is thus produced a permanent thin edge portion with a f soft andexpandable center portion.

This insulating bat or strip as described and as essentially shown in Fig. 2 may, with the changes hereinafter described, be produced on a machine of the nature of and in accordance with the general method set orth in my prior Patent No. 1,713,309, of May 14, 1929. I ,have shown the essential and modified element of this machine in Fig. 1, referring to which 1 indicates thel bat alone suitably formed and traveling on tables 7 and 8 in the direction of the arrows between presser rolls 9. i/(n apron conveyer traveling over the table and around the appropriate rolls 10, 11, and 12 is shown at 13. The strips 6 are fed on to the bat at its edges and under the guide rolls 14. They thence pass to the needles 15 of the sewing machine which form the stitching 5. Actlng in conjunction with these needles (there being of course a plurality of 4the same) are presser feet 16 in the manner of an ordinary 100 sewing machine. The action-of these presser feet, acting in the ordinary manner, presses the bat 1 and the reinforcing strips 6 to a suficient degree to produce the desired relative thinness and compactnessat the edges of the bat, and the stitching extending through the strips 6 and the filling between them holds the filling in this relatively thin condition, resisting any tendency for it to spring back to its original thickness. If necessary an additionalcompression device,

acting ahead of the needles may be provided 1n theV form lof spring pressed rollers 17. After vthe reinforcing strips 6 have been applied and stitched to the filling, the liner sheets 2 and 3 may be applied to the top and bottom of the bat in any suitable manner, such as by the same mechanism shown in said prior Patent No. V1,713,309forapplying the liner sheets 5 and 5a. The utility of a thin edgedlinsulating strip formed and constituted as described maybe explained as follows:

In Fig. 4A indicates adjacent studdings 0f a wall in horizontalsection and B indicates lsheathing applied thereto. The lath air spaces F between it and the sheathing and air spaces G on the opposite sides between it and the interior finish or wall forming elements4 C and D. Thus two separate airy spaces are provided instead of one which,

as anyone skilled in the art will see, adds greatly to theinsulating qualities from this standpoint alone.

But in addition to this the flexing of the insulating strip to this position with its edges so compressed and confined contributes another insulating factor. This resides in the expansion of the fibrous body 1 at the center, as shown in Figs. 3 and 4, which results from the fact of the bending of the material while the edges are held fast in their compressed condition.;\Were they not so held fast the insulating strip would not accommodate itself to the position shown but would have a tendency to crinkle or break indiscriminately throughouty its width and there would be a further tendency for it to expand and pull away from the liners at the edges where it must be fastened instead of expanding as aforesaid at the center where such expansion adds to its lnsulatmg qualities.

In Fig. 5 the same 'action is shown Where product being compressed throughout a substantial width to a greater degree than intermediate portions thereof.

2. A padded product for the insulation of the walls of buildings and similar purposes which comprises in combination an inner flocculent mass of fibrous material confined between liner sheets having relatively greater tensile strength, the longitudinal edges of the product being compressed to a greater degree than intermediate portions thereof and being secured in such compressed state of lines of lstitching extending through said fibrous material.

3. A padded product for the insulation of the walls of buildings and similar purposes which comprises in combination an inner occulent mass of fibrous material confined between liner sheets having relatively greater tensile strength, the longitudinal edges of the product being compressed to a greater del ree than intermediate portions thereof and eing secured in such compressed state by lines of stitching, the lines of stitching passing through reinforcing strips extending along said longitudinal edges.'
