coMrosIrE SHEET or MATERIAL.

and MosEs SAMUEL, 'citizens of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and vuseful Improvements in Composite Sheets of Material; and we do hereby declare the following to be -a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make'and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

The invention relates to a sheet of material that is composed of several layers of different materials, so that the resultant product can be cut into forms or used insheets for numerous purposes to be described hereinafter. i

The sheet of material is built upon a base or foundation of a flexible material, which is then treated with an adhesive and then this adhesive is in turn subjected t0-a layer of particles of strips of a suitable and desired to which consistency, according to the uses the sheet is to be put.-

Figures -1, 2. and 3 of the drawing are views of difierent kinds of sheets, and Fig. 4 is a section'of a sheet of a modified form. In making up the sheet of material, first a base is provided, which is of a flexible material and is preferably composed of a sheet or strip of paper, cloth or leather, although duck, felt, buckram or similar material may be employed. This sheet is coated on one face, although both sides can be treated, with a coatin of-adhesive such as shellac, rosin, tar, asp altum, wax or cement. The

next stop is the placing of material on the adhesive to form the body of the sheet, and this layer can be absorbent or non-absorbent, according to theuses to which it is to be put.

This layer is preferably formed of felt, fur, cotton or wool yarn, cork, leather and simi-.

sive is placed, or blown, a layer of felt 12' which is filled in at all its interstices so that it is fairly or completely covered. This resultant sheet may be rolled. This sheet is Specification of Letters Patent. Application filed January 11, 1908. -Serial No. 410,338.

Patented Oct. 2 6, 1909.

"useful for cutting into fornis for box-toes, that is the-forms are treated with shellac or similar substance and then formed or. lasted in the shoe, and when dry it'will support the toe of the shoe permanently in place. This product-can also be used for shoulder-pads, "stiffening for coat-fronts, and other like (purposes.

v The advantage of this roduct over plain sheets of felt as previously used, is the ab-' sence of waste, ;as all the felt can be used because it can be made of old hats and roundings, and these, when cutup and put on the adhesive, are entirely used and there is no excess material. Again, the felt, when out up before it is blown or laid on the adhesive layer, is more absorbent by having any worn surfaces cut up and-destroyed, in fact the felt from hats or worn or shiny goods can be split before mastication so that a perfect absorbent surface will result. This absorbent quality helps the shellac to penetrate the felt and form a necessarily stiffer product when it dries. The felt, when applied to the sheet, can be scratched or it may be fur, and blown or mat-ted on the adhesive.

In Fig. 2 is shown a sheet where the felt is cut into strips or shreds 13', and then filled in with small pieces. These sheets can be used for insoles and similar articles.

We illustrate in Fig. 3 a sheet with a mixture of felt 12 and cork 14, which combination is good also for insoles, since the cork. will resist all tendency to mat, and being non-absorbent, in cont-radistinction from the felt, affords better ventilation in an article where' it is necessary. The cork can be ground up with the felt and blown on the adhesive 11. Mica can also be mixed with the felt, or it can be placed on the base .or backing first, and this combination of material is perfectly adapted for electrical in sulation, and asbestos with felt is well suited for insulation for heat, such as pipe coverings. Leather can also be used with the felt, and leather can be mixed with cork. In fact, we do not wish to be limited to any one combination, since the sheet of material, so built up, can be used for so many different purposes.

It will be understood that this product can be colored, embossed or otherwise ornamented, and also punched or pressed into fancy shapes. The building up of the body portion or layer of the sheet may be done' The corrugated sheet is preferred some instances, such as where it is used as astiifener for coat fronts. Coat fronts roll back when they are worn a while, and the stifiener gets set in a position which is not desired, as it has not strength enough to hold the coat stiff; 1f thestiffener shown in Fig. 4 is used with the corrugations, horizontal for instance, the stiffener sheet would be strong enough to hold the coat front in a dressy position for the life of the coat. I

The adhesives used in these sheets are of a number of kinds, but for certain purposes we desire to employ a resinate that 1s amenable to heat or to heat accompanied by moisture. The cementitious substance of this class that is tractable as above indicated, is useful where, if the sheet of material has been rolled, cracked, bent or it is desired to shape it to another form, it can be heated and then allowed to dry in its new or restored shape. Some adhesives are amenable to heat when accompanied with moisture, and when these are used and subjected to a pressing or ironing and moisture they can be easily restored to a required shape or be given a new form. The adhesive also acts as a stiffener for the backing, and likewise for the wholesheet of material. It also enters any absorbent of the body port-ion and coats the body portion next to thebacking, and thus artificially .stiffens the sheet, and thisis articularly desirable for resiliency and sti nes's where the adhesive is amenable to heat or heat accompanied by moisture.

The base of the sheet of material can be made of carpet or any sheet having a pile thereon, such as velvet or corduroy, and it can also be of a nature having loops such as astrakhan cloth or the so-called nigger wool cloth. The advantage of this backing is that it gives a chance for the body portion of the sheet and also-the adhesive to have a better purchase. The backing may consist of a wide mesh fabric coated with cementitious substance of a suitable adhesive.

The body portion may be made, in addition to substances previously referred to, of fibrous material orfiber such as hair, bristles, bamboo fiber, Japanese hair, or woolen or cotton threads or tampico, which fibers can be mixed with the heavier or larger pieces or strips of material, or can be placed on the backing as a first layer or as a separate layer to give'a spring or stifiness to the body portion.

The lower layer of the body portion, whether made of felt, cork, leather or other material, is made up of pieces placed relatively close together, but, .,leaving interstices or' spaces between them. When smaller or finer particles are deposited or sifted on the larger pieces, these fine particles will sift down in among the larger pieces and shreds,

and thus present, when finished, a relatively firm smooth product. The body portion may also be formed of a loose fiufiy fibrous material, such as fur, and this may be blown or suitably deposited on the adhesive alone, or it can be mingled with pieces of felt or similar substance. When felt and other absorbent materials are used as a body portion they may be impregnated with a stiffening substance, and thus'be artificially stiffened to hold their shape when the sheet of material is used for purposes as a stiffener.

In order to provide a larger number of in.-

terstices between the felt and in some uses to which it is to be put, to provide more stiffness, the shreds or the hair used in this sheet of material can) be corrugated or fluted.

Having thus described our invention, what we claim is g A sheet of material consisting ofa flexible backing having an adhesive thereon, de tached pieces of material to form a body portion placed on the adhesive, and fine particles of material sifted thereon to fill up the spaces between the pieces to form a' smooth product.

In testimony, that we claim the foregoing, we have hereunto set ourhands this 10th day of January 1908.
