Thispresent invention relates to new and useful improvements in a building insulator and has for its primary object the provision of an improved and simple form-of insulator which may be used in the wall, floor or roof structure of a building to insulate the sa me by forming air pockets therein.

Another object of the invention resides in the provision of a simple form of insulator which is produced in a single blankwithout waste of material andwhich is readily folded to compact form and positioned between parallel members of the building structure with blank secured on the outer face of two of said parallel members.

A further object of the invention resides in the provision of a building insulator of the single rectangular blank without waste of material and scored ormarked to indicate the manner of folding the blank for positioning the same in the frame work of the building structure for forming 'dead air or vacuum pockets therein while the longitudinal edges of the blank are secured on the face-of the frame member, outside of the pockets.

A still further object of the invention resides in the provision of a building insulator of the character stated which. is constructed from a blank without waste of materialand is out and scored in such a manner that it will be noted that the blank t; is of elongated form and has a right. angle cut 7 at. each coris snugly engaged in the spaces between the frame members of the building structure with the longitudinal strips at the sides of the blank engaging the edges of the frame members while the transversestrips at the ends of the blank are folded in the'spaces with their extended free extremities turned at a right angle and resting in the dead air or vacuum pocket formed by the insulator.

A still further object- .of the invention re sides in the provision of a building insulator of the character stated which may be used in any portion of the frame work of the building and may be readily secured in position or removed, as desired.

' T heinvention has for a" still further object the provision of a building insulator of the character stated which maybe manufactured blank at the corners thereof;-

at small cost from an appropriate material such as stiff pa'per,cardboard or other appropriate material, specially treated or otherwise and which may be transported or stored in blank form without loss or Waste of space. 5'5 To the accomplishment of these and related objects as shall become apparent as the description proceeds, my invention resides in the construction,combination and arrangement of parts'as shall be hereinafter more fully described, illustrated in the accompany 111g drawings and pointed out in. the claim hereunto appended. turned out longitudinal edges of the insulator V The invention will be best understood'and can be more clearly describedwhenTeferen'ce is bad to the drawings forming apart of this disclosure wherein like characters indicate In the drawings Y c Figure lis anelevation of the blank from which the building insulator is formed;

It is also seen that this building insulator may be constructed from stiff cardboard or the like, either treated or untreated, without any waste of material whatsoever and for shipping or storing. purposes, the blanks may be left flat. 7

As the construction of the device has thus been described in detail, brief reference is had to its use and modus operandi: The

building insulator is adapted for use in fioor' structures, wall structures or-roof structures and when employed in either structure may be used from either side to form an insulator air pocket or vacuum space between two of the main members of the structure. WVhen used in a floor structure, the insulator is positioned longitudinally between two of the joists and will extend the length as well as the width of the space therebetween with the out-turned ortions of the side members 9 of similarly positionedbetween adjacent studs and secured thereto in a; like manner. Likewise. when the insulator is employed in a roof structure, it is applied between adjacent rafters and secured in position in the manner corresponding to that specifically set forth for incorporating the insulator in a floor structure. r

Vvherever used in a building structure, the insulator forms a pocket which is effectively closed and reinforced at the corners thereof and thus serves to provide a com- Having thus described my invention, what I claim as new and desire to secure by Letters Patent is V A building insulator including the combination with a pair of upstanding parallel main structure members and a pair of transverse parallel main structure members connecting the upper and lower" endsvof said upstanding parallel main structure members of a blank having side members and end members formed thereon without waste of material; said side members and end members being adapted to be bent at right angles to the main portion of the blank and against the opposed inner faces of the adjacent transverse parallel main. structure members with the freeextremities of the end members turned in against the side members andthe latterhaying outwardly bent edgesfor engagement-onsthe narrow edges ofthe up-t,
