UNITED STATES PATENT OFFICE.
FLOYD W. ADAMS, OF EAST ORANGE, NEW JERSEY, ASSIGNOR TO THE BARRETT COM- PANY, A CORPORATION OF NEW JERSEY.
VENEER BOARD AND METHOD OF MAKING SAME.
.AppIication filed December 14, 1920. Serial No. 430,725.
In practicin this invention a sheet of material containing felted fibers may have incorporated therein comminuted particles of bituminous material by introducin the comminuted waterproofing material wit the paper pulp into the vat of an ordinary papermaking machine, whereupon the waterproofing material becomes incorprorated in the sheet as the same is made. lies or layers of the sheet are superposed uponeach other and hot pressed to melt the waterproofing material and firmly 'unite the plies or layers. The layers are preferably plied together while in a wet state to cause felting or matting of the fibers alongthe surfaces, thus initially joinin the plies and making a more mechanical y perfect product. A thin strip of material, such as wood, is hot pressed onto the outside surface of the united layers and is joined to the same by the cementing action of the waterproofing material that has been incorporated in the layers or plies.
The invention will be understood from the description taken in connection with the accompanying drawings, in which Fig. 1 is a side view indicating the article before it is pressed.
Fig. 2 is a somewhat diagrammatic view of a, machine for pressing the article.
In the drawings reference character 1 indicates a plurality of sheets or plies that have been superposed upon each other, preferably while wet, and 2 indicates thin strips of material, such as wood for example.
The base 3 of the pres shown in Fig. 2 is provided with. a heating chamber 4, into which heating and cooling fluids may be introduced. and withdrawn through the pipes 5 and 6, and the presure member 7 of the press is likewise provided with a heating chamber 8, into. which heating and cooling fluids ma be introduced and withdrawn through t e pipes 9 and 10. The layers 1 containing fibrous material and commmuted waterproofing material may be inserted in the press and by means of heating fluid in the chambers 4 and 8 the temperature may be increased sufliciently to melt the waterproof-. ing material, and the pressure may then be applied so as to firmly unite the sheets and produce a substantially homogeneous product. A thin layer of wood veneer .or thelike may be laid on one or both sides of the same and it may be again subjected to a hot pressing operation in the press, whereupon the waterproofing material fuses and firmly cements the veneer to the pressed product. The surfaces of the veneer which contact with the inner plies may be roughened so as to cause amore firm adherence to the plies. While the pressure is applied, cooling fluid may be introduced into the chamber t and 8 so as to cause the waterproofing material to solidify or set.
Instead of first uniting the layers by the hot pressing operation, as above described, and subsequently uniting the strips of veneer thereto, the strips of veneer may be applied to the layers that contain the fibrous material and waterproofing material as indicated in Fig. 1, and all pressed at once in the press at a sufficient temperature to fuse the waterproofing material.
In practicing this invention pitch of a melting poi t of about 250 F. to 300 F. has been fo nd to give satisfactory results when used as the waterproofing material, and it may be used in such quantities that about 50% to of the interior of the final article is pitch. The pressure applied may be such that the volume of the layers containing fibrous and waterproofing material may be reduced to about one-half that of the original ing a plurality of strips containing felted fibrous material and comminuted Waterproofing material, and hot pressing a sheet of other material against the same.
2. The process which comprises superposing a plurality of strips containing felted fibrous material and waterproofin material, and hot pressing a sheet of 0t er materialagainst the same.
3, The processwhich comprises superposing a plurality of strips containing fibrous material ,and comminuted waterproofing material, and hot pressing a sheet of other material against the same at such a. temperature that the waterproofing material will become melted and unite said sheet to said strips.
4. The process which comprises superposing a plurality of strips containin fibrous material and waterproofing material while in the wet state, and hot pressing a sheet of thin stifi' material against the same.
5. The process which comprises superposing a plurality of strips containing fibrous material and comminuted pitch, and hot pressing a sheet of other material against the same at such a temperature that the pitch will become melted and unite said sheet to said strips.
6. As an article of manufacture, a board emme comprising a strip containing felted fibrous E material and waterproofing material united to a sheet of rigid material.
7. As an article of manufacture, a board comprising a strip containing felted fibrous material and waterproofing material united 25 to a sheet of wood.
8. As an article of manufacture, a board comprising a strip containing felted fibrous material and pitch of a melting point of about 250 F. to 300 F. united to a thin at Sheet of wood.
9 As an article of manufacture, a board comprising a stri containing felted fibrous material and pitc united to a thin sheet of wood, said article having been reduced by 35 pressure to about half its original thickness.
In testimony whereof I affix my signature.
