'Waterman, Fort Atkinson, Wis., as- Signor to James Manufacturing Company, Fort Atkinson, Win, a corporation of Wisconsin Application June 10, 1940, Serial No. 339,637
The present invention relates to insulation made up in sheets of considerable thickness and particularly adapted to be positioned between v erecting operations. e
The principal object of the present invention is to provide an insulating bat, which is adequately stitched, in spaced rows iorming a compact and firm bat suitable for handling, but having means which add to its insulating qualities, and to prevent moisture from entering the bat through the stitching cords, and provide a dead air space to thereby further seal .the bat against the entrance of moisture or transfer of heat.
It will be understood, that when bats are stitched, in reasonably closely spaced rows, considerable moisture is permitted to pass into the bat, .through the stitching cords. I I, therefore, provide means for sealing the stitching against being exposed to moisture.
It will be further understood, that when insulating material is placed between two strips of paper, and the like, and stitched, the paper is somewhat broken where the cords pass through the paper. I, therefore, apply asphaltum strips, at a temperature which will permit them to seal the broken covering and saturate the cords. thus to doubly seal the insulating material from the exterior.
I provide a vapor seal membrane, on top of the asphaltum strips, which is applied while the seal the strip edges together; thus insuring against moisture passing into the insulating material between these edges.
The edges of the vapor seal membrane are also sealed to the adjacent strip edges by asphaltum. Thus. the flange comprises three strips and two asphaltum layers adding to the firmness of the bat and providing a strong strip for nailing to the studding.
To these and other useful ends, my improved bat consists of parts, combinations of parts, or their equivalents, and method of manufacture, as hereinafter set forth and claimed and shown in the accompanying drawings in which:
Fig. 1 is a transverse end section through my improved bat showing how the bats are attached to the face of the studding.
Fig. 2 is a perspective view of a short length of my improved bat having a fraction of the vapor seal membrane and a portion or one of the asphalt strips removed, illustrating the position of the asphaltum strips and a portion or the stitching which is indicated in the bat by dotted lines.
-:Fig. 3 is an enlarged section of my improved bat,- taken on lines 3-3 of Figure 1.
Fig. 4 is a transverse sectional view of a modification. 7
Fig. 5 is a perspective view of the modification as illustrated in Figure 4.
My improved bat comprises an inner strip of paper or any other suitable material, designated by reference numeral lo, the outer edges being asphaltum is more orless in a liquid state,
whereby the membrane will be securely held to the strips, in a manner which will be just as strong and firm as if this membrane was also stitched to the bat, and whereby dead air spaces are provided'betweenthis membrane and the adjacent covering sheet.
In the present invention, I surround the insulating material with paper coverings, having their edges extended outwardly, for a short distance, at one side of the bat, for contact with the edge of the studding. The contact between these two covering edges is made by means of a strip of asphaltum which, when assembled beextended at right angles as at H-ll and then being bent outwardly so as to form flanges l2-l'2 which are adapted to lie on the studdlngs 9-9 as illustrated in Figure 1.
The insulating material is placed within the trench formed by members III and II and designated by reference numeral l3. This material may be of any approved. type, of which there is many in use. Insulating material I3 is covered by a suitable sheet or paper II, the edges lying on flanges l2 and being sealed thereto by means of asphaltum strips l5. I
After the insulating material l3 has been inclosed. as outlined, the assembly is then stitched in spaced rows as at It. This stitching may be done in any manner, and extends through members l0, l3 and I4, as clearly illustrated in the figures. trenched along the line of the stitching, as clearly illustrated in Figure 1.
I apply thick strips of asphaltum I! over the tween the strips at the proper temperature, will s itching, as illustrated in Figures 1 an at Members Ill and It will be slightly temperature so the asphaltum will, to some extent, flow into the trench formed by the pull of the stitching and seal the enlarged openings in member l4. Thus the stitching is sealed from the surface by strips ll.
After the asphaltum strips H are applied, as illustrated in Figures 1 and 2, I apply asphaltum to the edges of member", as at l8l8, and then lay what I term a vapor seal membrane IS, on strips l1 and I8 so it is bound and sealed thereto; and, because of the thickness of strips Hand l8, a dead air space 20 is provided. Thus, it will be seen, that the stitching is protected against moisture contact, and that a firm and substantial bat, having dead air spaces, is provided, and that the bat is suitable for application between the studding, as illustrated in Figure 1, and that the overhanging edges of the paper are sealed together, by means of asphaltum so as to form a tough fastening, through which to drive the attaching nails.
It will be understood that members l0, l4 and I9 may be made from paper or any other suitable material, the preferred material being heat transfer resisting and, under some circumstances, they may be made from asbestos, or otherwise.
Clearly, any form of stitching may be used for holding members l0, and M, in spaced relation. It will also be understood that members l5, l1 and [8 need not, necessarily, be asphaltum. Some other material may be found to be more suitable. It will also be understood that space 20 may be varied, somewhat, or practically eliminated because of the depth of the trenches in member l4.
Vapor seal membrane I9 is preferably somewhat heavier than members III and I4 and treated with certain material so as to make it moisture proof.
In Figures 4 and 5, I illustrate a modification which is considered somewhat of an improvement over that shown in Figures 1 and 2. Many of the parts, however, with which this modification is made, are similar to the parts shown in Figures 1 and 2, therefore similar numerals are used to designate similar parts.
In manufacturing the bat shown in the modification, I provide two paper sheets 2525 and fill the space therebetween by means of insulating material l3 and then stitch the assembly together as illustrated in the same manner as the stitching is applied to the bat illustrated in Figures 1, 2 and 3. After the bat is thus formed, I apply asphaltum strips l8 over each row of stitching and on opposite sides of the bat thus formed as illustrated, after which the bat is placed in the trench formed by members H) and II. I then apply my vapor seal membrance H, as clearly illustrated in Figures 4 and 5. The complete bat thus formed will be moisture proof from the inside as in Figures 1 and 2 and partially moisture proofed from the outside as illustrated in Figures 4 and 5.
Generally the bat is applied to the studdin on the inside of the building, as illustrated in Figure 1, thus to prevent the usual moisture in the building from finding its way into the insulating material and if a slight amount of the moisture should find its way into the insulating material, because of the single sheet of paper l0, it will soon be absorbed by the adjacent atmosphere.
In Figures 4 and 5, I illustrate a at which is sealed on the outside as well as on the inside and a dead air space is provided on the outside as well as on the inside of the bat. Thus to doubly insure against heat transfer and to also seal the openings made in the paper sheets 25 and on opposite sides of the bat.
Generally when the building is surrounded by metal or wood sheathing, there will be a dead air space between the bat and the sheathing and, if the inside of the building is sealed by means of corregated iron or the like, the bat will be protected against physical injury and also will be partially in contact with the dead air spaces.
Clearly the bat shown in Figures 1 and 2 and in the modification may be variously applied and surrounded so as to meet the various conditions encountered in buildings of various types.
Having thus shown and described my invention, I claim:
1. An insulating bat of the class described, comprising a felt mat and covering sheets positioned on opposite sides thereof, said covering sheets and mat being stitched together in spaced rows, narrow relatively thick sealing adhesive strips positioned on the exposed stitching on one side of the bat, a sheet of vapor seal covering positioned on said strips to thereby form dead air spaces on one side of said mat.
2. An insulating bat of the class described,
' comprising a sheet having its side edges bent upthe exposed stitching adjacent said flanges and over the flanges, a vapor seal membrane'positioned on said sealing, adhesive strips forming dead air spaces between said vapor seal membrane and the adjacent sheet.
3. An insulating bat,of the class described, comprising a felt mat having covering sheets on opposite sides thereof, said mat and covering sheets being stitched together in spaced rows, narrow relatively thick sealing, adhesive strips positioned on the exposed stitching, a covering sheet positioned on said strips on one side of said mat, the side edges being bent and contacting the edges of said mat and then being bent outwardly forming flanges substantially in the same plane as the adjacent first covering sheet, sealing, adhesive strips on the top of said flanges, another covering sheet positioned on said flange adhesive strip and adjacent strips, to thereby form dead air spaces on opposite sides of said mat and outwardly extending flanges on the side edges thereof. 4
