MASTER-BOARD.
SPECIFICATION forming part of Letters Patent N0. 757,060, dated April 12, 1904.
Application filed July 16, 1903. Serial No. 165,740. (No model.)
To all whom, it may concern:
Be it known that I, HARRY E. SHARP, a citizen'of the United States, residing in Hartford,
. in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Plaster-Boards, of which the following is a specication.
This invention relates to and has for an object to provide an improved plaster-board or Substitute for lath.
It is desirable in providing a surface for receiving plaster for walls and ceilings to have the body upon which such plaster-receiving surface is located of a material which will resist water-not only moisture from the atmosphere, but the moisture from the plasterand to enable the surface to properly retain the plaster it is necessary that it should be capable of yielding' to the plaster or the moisture from the plaster to such an eXent that the plaster and the surface of the body will commingle and the plaster be thereby securely held and become practically homogeneous with the board. By having the plaster-board made of a material which is impervious to water or the moisture of water and a covering or coating thereon giving a surface which is pervious to the moisture of the plaster a board will be had which will support the plaster without being distorted or warped and which will not through atmospheric changes cause the plaster to crack. It is also desirable in fireproof construction to make the support for the plaster practically iireproof. If the outer surface is made of a fireproof or hre-resisting material, it will greatly add to the lire-resisting properties of the wall generally.
The boards may be made in convenient sheets for application to the furring and will have a body portion consisting of some plastic, such as paper-pulp or strawboard, which will be rendered-waterproof by the application of a coating of waterproofing material. Then the board will receive the application of a coating of fire-resisting material pervious to moisture, but capable of adhering to the waterproofed board.
In the drawings accompanying and forming part of this specication, Figure 1 is a crosssection of a portion of board, illustrating the present invention. Fig. 2 is a side view thereof. Fig. 3 is a perspective illustrating the application of the board in construction, and Fig. 4. is a form of fastening.
The board, as herein illustrated, is shown as made up of a body portion t, which may be paper-pulp, strawboard, or some other suitable material, which, if desired, may be a plastic. If the boards are to be used for plain surfaces, they will be in sheets of suitable sizes for convenient handling and application. The body portion of the board is shown as covered with coatings 5 of some material which is impervious to water or the moisture from plaster, upon which laminations are imposed surfaces or coverings 6 of material pervious to the moisture from the plaster and which, if desired,` may be made of a brcus material and may also be capable of resisting fire.` The surface or covering 6 will cover practically the entire surface of the coating 5, whereby the plaster will be received by said pervious surface and kept from the impervious coating. `rIhe coverings of pervious material if ireproof will by completely enveloping the board and covering practically all portions of it protect it from fire.
In Fig. 3 several sheets 7 of the board are shown as applied to metal furring 8, supported by the beams 9 of the building and secured by suitable fastening devices. The fastening device illustrated in Fig. l comprises a hook 10 to embrace the furring, a serrated or screwthreaded stem 11, and a bur l2. The bur will be pressed down or screwed on and the end of the stem cut ofl". The boards may be provided with apertures 13 for the better securement of the plastering.
When wooden furring is used in the structure where it is desired to employ this plasterboard, the board may be secured to the furring by nails.
Thus it will be seen that a board is produced which is capable of resisting fire and moisture. Fire cannot get through to the waterproof portion of the board. The outer covering or surface Will yield to the moisture of the plaster and permit it to become practically homogeneous With the board; but the inner Waterproof portion Will prevent the same from yielding to the Weight of the plaster and becoming distorted, as the board itself does not as a Whole become impregnated with the Water from the plaster. The plaster has a dry unyielding su pport which Will not become moist by absorption of moisture from the atmosphere or from accidental contact With Water, so that there will be no cracking of the plaster incident to the shrinking and swelling of its backing or support.
It Will be apparent that the several thicknesses or laminas are illustrated out of their true proportion for the greater ease of description.
The backing or foundation Will be of a convenient thickness for the special requirements of the Work in hand, and the coatings will respectively be thick enough to perform their several tasks.
Having described my invention, I claim- 1. A plaster-board impervious to moisture and having a surface pervious to moisture.
2. A plaster-board having a lamina of a Waterproof material, and an exterior covering of iireproof material pervious to moisture.
3. A plaster-board comprising an interior lamina of Waterproof fibrous material and an exterior of non-Waterproof ireproof brous material.
4. A plaster-board comprising a body portion of fibrous Waterproof material and a coating upon such body portion of non-Waterproof lireproof fibrous material.
5. YA plaster-board having an interior portion capable of resisting moisture and its entire plaster-receiving surface capable of resisting lire and of resisting moisture but slightly. 6. A plaster-board capable of resisting the moisture of vplaster and having a surface capable of yielding to the influence of the moisture from plaster and of being penetrated thereby.
7 A plaster-board capable of resisting the .moisture of plaster and having a surface capable of yielding to the influence of the moisture from plaster and of being penetrated and partially disintegrated thereby.
8. A Wall or partition comprising a plasterboard capable of resisting the moisture of plaster and having a surface capable of yielding to the influence of the moisture from plaster and of being penetrated thereby; apertures through the board; and plaster upon the board interlocked With such apertures and commingled with the surface of the board.
9. A plaster-board comprising an interior lamina of waterproof material and an exterior of ireproof material.
10. A plastic board comprising an interior lamina of Waterproof material and an exterior of non-Waterproof material.
