Aug. 12, 1941. H. D. POWELL INSULATION OF BUILDINGS n .l .2; ...iL/rif, .31.6

Filed April 26, 1959 #any ZZ fam/a that have not been used for Patented Aug'. l2, 1941 UNITED STATES PATENT OFFICE l tllitl Application Apru 26, 1939, serial No. 270,140

(Cl. 2li- 4) 2 Claims.

is to proa cham- The general object of this invention vide lwater-proofed or vapor barrier in bered wall.

An angle of carrying out the objects of the invention is disclosed when incorporated in connection with building structures having inter-wall chambers by lining said chambers with inflatable water-proof walled receptacle or bag to ilt into thechamber and hold such bag to form,v with charge, resistant to heat conduction, of nre-proof ilber as of rock wool to ll the chamber body as a sealing partition.- i

My invention relates toimprovements inthe method of inserting insulating material intothe spaces between the outside and inside surface covering of walls of houses and other buildings provided or filled with Such insulation material in the process of original construction. the means and methods of producing by such insulation a moisture proof condition oi' the insulating material and oi' the spaces vbetween the outside and inside covering or surface of such walls (to illustrate, as between lan outside sheeted, brick, stucco or other outside covering andv a plastered or other covered inside surface covering). and so preventing moisture from saturated atmosphere, the insulating material with the said wall coverings, passing through or causing condensation and moistening of the inside wall-surface, resulting in the loosening oi' paper or other ornamentation thereto attached.

Also my invention relates to and accomplishes a more even and uniform density of the insulating material when inserted and in place in said wall spaces.

My invention is particularly for the purpose oi use with rock; or mineral wool,- the ordinary material used for insulation, but it is adapted to the use of any finely divided material that may be insulating or similar purposes.

Referring to the drawing:

Fig. il is a vertical section ai an inter-wall chamber as receiving a charge ci collapsed lining e therefor;

rig. a is s view cf the inter-wsu Fig. l, with` the lining iniiated in said the wall: and

chamber oi chamber of Fig. 3 is a view oi' the iniiated lining oi the wall of Fig. 2, with said lining receiving a charge ci insulating material as rock wool.

- l accomplish the above stated Vobjects oi my invention by inserting in the spaces A to be filled between the two wall coverings, as divided yby storm or other source, by contact of i It also relates to the improvements in The space is thus illled 'iii studding or other partition, a moisture proof paper, or other interior smooth-surfaced, bag or receptacle B in a collapsed or ilattened condition, but of dimensions when-expanded to iit snugly and tightly the space to be filled with the insulating material. This receptacle B being so inserted in its collapsed form into the said space A is then expanded therein by the use oi' compressed air through pipe or hose H, so that it fits tightly around and against the several sides of the space to be llled and over such .inequalities of surface as may there exist. The receptacle being thus iltted to its place, the the insulating material C is inserted at its top in a uniform condition of density produced by previous division and aeration and fall freelythroughv the smooth sided receptacle, by gravity, until the space required is iilled.

The smooth'sides of this receptacle allow the material to fall by its weight without friction against and obstruction by the otherwise rough and uneven wall coverings (lath, plaster. etc.).

with an even and predetermined density that ministers both to economy of operation, material and eillciency. The waterproofed container eectually prevents moisture from either entering the insulating material, and

the insulating material within such water-procrear receptacle being dry and containing its evenly aerated dry spaces prevents moisture from passing to, or condensation forming' on, the inside wall surface.

Where necessary, other obstructions,

by reason of roughness or to insure the collapsed receptacle going down to the bottom oi' the space to be illled, I insert in the lower end of the receptacle either a permanent weight, or a weight W that may be recoveredby an attached cord S when the receptacle is in place and expanded.

i have illustrated my` said invention in the drawing hereto attached in which Fig. l is a cross section oi an ordinary constructed wall space A and showing the outer and inner surface coverings, and extending down through such'space the collapsed receptacle B extending from the sill or lower end of space A to its top, Where in the drawing a piece of outside wall covering is removed to give access to the space to be filled, both i'or inserting the receptacle B and for filling the same when expanded. Y

Fig. 2 is same asv Fig. 1 but with receptacle B expanded by the compressed air until it fits closely tothe sides of the space in the wall to be filled.

Fig. 3 is the same cross section of wall as in air pressure is released andy Figs. 1 and 2 with receptacle B expanded and insulating material Centering and partly filling receptacle B.

Having described my invention, and stated its object, what I claim as new is:

1. The method of insulating a building having an inter-wall chamber comprising the steps of establishing an entrance opening to said chamber, inserting through said opening a flexible wa11` water-proof container, projecting said container into said chamber away from the opening, and

building having an inter-wall chamber comprising the steps of removing a portion of the wall of charging said 'containerl with insulating material and thereby effecting the isolation of said material frommoisture laden air.

2. The method of effecting insulation of a H. D. POWELL.
