To all whom it may concern:

Be it known that We, JULIUs DE LoNG, a citizen of the United States, residing in the borough of Brooklyn, in the city of New York, in the county of Kings and State of New York,'and JOHN BAPTISTE D HOMERGUE, residing at the city of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Insulating Material for Building and Analogous Purposes, of which the following is a specification.

This invention relates to an insulating material for building and analogous purposes, such as is generally used in the walls of buildings as a fire retardant, and also used around electric conduits and junction boxes to prevent accidents sometimes due to contact caused by defective wiring. Materialsuch as the present invention has in View can also be used in partition walls to deaden sound, and further to a great advantage in keeping out heat, cold and moisture in all kinds of building structures.

To this end the present invention contemplates a laminated structure of fire proof and Water proofsheets of material, in such a manner that themaximum efiectiveness of each material used in making up the said structure is obtained. v

With these and other` objects in View, which will more readily appear to those skilled in the art as the description of thecase proceeds, the same consists in the novel Construction, combination, and arrangement of parts hereinafter more fully described, illustrated and claimed. a a

Referring tothe accompanying drawings, Figure 1 is a perspective View of a section of the material forming the subject of this inv vention. Fig. 2 is a perspective View of the water prcof covering, having one corner thereof torn apart to show its structure. Fig. 3 is a View similar to Fig. 2 but showing a much coarser fabric used on the water proof surface.

Similar reference numerals, designate corresponding parts throughout the several figures of the drawings,

Referring specifically to the drawings, the numeral 1 designates a water proof covering, which is formed of a base material 2, which may be oftough paper or some equivalent absorbent material, and which is adapted to receive a coating `of water proof material such as pitch or the like designated by the reference numeral. 3. When the pitch is applied, it is of course in a plastic state, and while it is this way a loosely woven fabric 4 is pressed firmly thereon, so that at the end of the pressing operation there is formed a Water proof covering consisting of the three elements just referred to. In Fig. 2 it will be observed that a relatively light fabric such as gauze is impressed upon the Water proof material, while in Fig.

'3 it will be observed a Very coarse fabric such as burlap, or the like, takes the place of the lighter one shown in Fig. 2. The purpose of placing this fabric in the makeup of this water proof covering is to keep it from breaking and separating, and more than this, greatly reinforces and strengthens the covering so that it is very'tough, and cannot be easily torn. Next to the water proof covering is placed a layer of asbestos 5, and next to this is placed a fibrous layer 6 composed of hair felt and asbestos fiber closely intermingled. This structure has then placed upon it a second layer of asbestos, and then again upon the asbestos is placed the fibrous layer above described. The asbestos and fiber are alternately placed, one upon the other throughout the structure until it has r'eachd the desired thickness, and an asbestos layer is the last one to be put in place. Upon this last sheet of asbestos is placed a covering of water proof material that has been. previously described anddesig'- nated by the numeral 1. The entire structure after being assembled is pressed together, the interior layers being preferably held together by any suitable binding agent, such as glue or shellac, so that a coherent laminated 'structure is formed that may be cut into sheets or strips that are adapted for Various uses in building Construction.

This insulating material is not only moisture proof but forms an excellent fire retardant, so good in fact, that it can be heated until white hot and yet cannot be burned, although the hair of the felt would become charred and the fabric and water proof material would slowly burn oe. Where the felting material is in two layers, as is shown in the present construction, it is practically impossible to destroy the one at the back from white heat appled to the other face, r

because of the efl'ective insulation afl'orded by the three layers of asbestos with the felting and asbestos fiber between them.

From the foregoing description it is thought that the many features and advantages of the present inventon will be readily apparent to those skilled in the art, and the same will be easily understood without further description.

We claim:

1. An insulating material 'of the class described including outer waterproofed covering sheets comprsing a base, a waterproof material appled thereto and a fabrc pressed onto said` waterproof material, inner protective sheets, and fibrous' material arranged between said i inner protective sheets. I

2. An insulating material of the class described comprising outer water proof cover- JULIUS DE LONG. JOHN BAPTISTE D'HOMERGUE.
