Man-made studs and lumber
Kind Code:

To make one man made stud or sometimes called lumber sandwich adhesive is applied to both sides of the inner core #(16) and one is positioned on each edge of one out side piece #(10) When using two pieces for the inner core #(16). Then place the second out side piece on top to complete the sandwich. Now glue in a #(12) end block in both ends to complete the stud. When making one stud at a time the stud must be clamped or weighted till the glue dries. If you make a one piece #(16) inter core for more strength than no end blocks #(12) will be required.

To make more than one stud at a time lay flat a large outer sheet #(10) next lay down the one or two piece inner core that has been applied with adhesive #(16) all across the outer sheet when another #(10) outer piece is placed on top this will complete the sandwich for several studs or pieces of lumber when sawed to a desired width. By repeating this process several times the weight of the pile will eliminate the use of clamps till the glue dries. A mill may want to repeat this process by making several piles.

FIG. 3 shows a section of a large sheet using a #(16) solid inner core when more strength is important, and this will eliminate the use of the #(12) end block.

Because mills are now making long sheets that can be used as #(10) out side piece man made lumber can be used to make every phase of the building trades. As joists, sills' rafters to mention just a few of the uses.

I claim:

1. Man made lumber called lumber sandwich is lumber made from materials called seconds or materials that are normally thrown away or discarded the material is layered and held together with adhesives as shown in US/60717,981 PPA there is an inter core and a side on each side of the core the core may be made in one or more pieces but for strength is usually made with one piece each piece of lumber may be made as one piece of lumber or made in larger sheets and cut to lumber size after the adhesive dries saw dust shavings wood particles chips are all board seconds or wood by products and can be used to make lumber. man made studs and lumber may be made in all dimensions widths and lengths to accommodate more insulation for sound and warmth. Lumber has always been cut and made from trees but to make lumber from waste and chips will save the trees a product of the future in it that will move home building into a factory section will be built and moved to a site where it will be set up and completed in a day or two. Man made studs may be slotted or drilled for running all wire as electric, etc this will be a big savings for all installers. Block #(12) should be used on both ends of studs for a better nailing surface but is not needed when #(16) inner core is used when nailing on siding or plaster board inside of the wall the use of screws instead of nails will make it much stronger. Man made lumber has no knots to nail into or knots that fall out no cracks no splinters no warp no twist no bark making it all stronger and easy to work with will also make all stronger needs no grading saving more trees and labor.

This invention is to make lumber, using waste and by-products as saw dust, wood chips, shavings, straw. Large mill board that have been graded as rejects, now may be turned into lumber.


with all the talk about saving our forests, now we are doing something about it. With man-made lumber. Lumber has always been made from trees, now to be made from waste products. Patent U.S. Pat. No. 6,358,352,131 by Ernest W. Schmit, Mar. 19, 2002, a step forward saving our trees, making better lumber from bad.


The big advantage of man-made lumber is the big savings of our forest. Also using our waste products and sheets of materials that have been classified as rejects. Kiln dried will be a word of the past.

As man-made lumber can be glued up in large she, stacked in piles, till the glue dries, the weight of the pile will automatically eliminate the use of weights and clamps. After the glue dries, the sheets are than cut to desired widths, and will require no sorting or grading.

Carpenter work will be made much easier, because no crooked boards, no warping, no twisting. When used for corners, sills, headers, because of the clean cuts will fit nicely together.

The studs could also be drilled with holes or slotted for all wiring.


FIG. 1 Man-made lumber set on one end as you would set a stud in construction, the front showing the three parts two (#10) outer pieces and one (#16) core piece. Also shows the top of the stud where a (#12) block has been glued for a better end nailing surface. The (#12) Block may also run the full length of the stud or lumber, where more strength is required.

FIG. 2 Is the same piece of lumber that has been pulled apart to reveal all of the different parts. Before it is glued and after it has been sawed to a desired width.

FIG. 3 Shows man made lumber made with larger sheet for production purposes before it is cut into different widths for marketing


    • 10 Out Side Piece
    • 10 END BLOCK
    • 14 Holes for Wire
    • 16 INNER CORE


There are basically only two side pieces to make a stud or lumber, the side pieces (10) are glued to each side of the core (16). The core (16) for a stud may be made in one or more pieces. If strength is a factor than the core should be made in one piece. If two pieces are used leaving a core with a space in the center, than a end filler block (12) should be used in each end for a better nailing surface, and also be sawed if a shorter stud is needed.


FIG. 3 shows stud and lumber made in sheet form for production purposes, and drying time before it is cut to widths for marketing.


Lumber made from by-products are naturally made with savings, as it is very costly to get the trees to the; mill before it is sawed into lumber. There is a great supply of lumber by-products to be used for Man-made lumber that will create a very large market.
