,lowing is specification.
The objetat of my invention is to provide a plaster b/oard of simple and durable construction t'b be used as a substitute for lath and plaster now incominon use. '1
' More spcificially it is my object to provide a plasterboard which may be constructed of inexpensive materials and may be made by continuously o erated machinery, and that isfreinforceci and stren honed by means of a number of stran s of cheap twine 50 arranged in position within the plaster. board that the nails used in connecting the plaster board to a building may be passed through or close to the stranded 'twine, and thereby prevent the nailgfr'om breaking the plaster board, and also t1) hold the parts of the plaster board together in. the event that it should become cracked or.
broken.
My invention consists in the construction of plaster board whereby the objects contemplated are attained as hereinafter more fully set. forth, pointed out in my. claim and illustrated in the accompanying drawing, in which Figure 1 shows an elevation of a portion of a wall provided with my improved plaster board. 'liig. 2 shows a plaster board cmbodying mytinvention with a part thereof broken away to show the twine, and Fig. 3 shows an enlarged detailed sectional View through a section of the plaster board emying my invention. Referring to the accompanying drawings and particularly Fig. 3 thereof, it will be seen that the plaster board is formed of an under layer 10 which is preferably paper.
On topof it is a layer 11, which is made of lnster, which preferably contains: a bin' material such as hemp, thoreegf l y comn ingled with the plaster. Extending through this layer of plaster is a series of strands of twine 12. These strands may, if desired, be made of ordinary binding twine or' a cheap kind of small rope. The said twine is placed on top of the paper and the plaster is pressed into position around the twine to thoroughly embed the twine .in the plaster. The top surface of the plaster board is 'formed by means of a layer 13 which is preferably of a mixture -of asbestos sand and cement iii dry form. This is placed upon the plaster 11 during the time that ,the plastcr is wet, and sufiicient moistureisattracted' by the asbestos sand and ucenientfio cause the cement to harden and vrHowev'er, duringfihe manufacture. of theplaster'board this to layer of dry sand and cement is'susceptib e of being readily 'and easily smoothed over and pressed into the plaster board to form a smooth, flat and hard surface afterthe cement has taken up moisturefrom the plaster and has set andhardened.
' It is obvious that by the use of strands of 'twineextending throu h the plaster board, if the plaste'r board s ould be'cracked or broken at any point, the parts will be held together by means of the twine, and by having the strands of'twine extended both longitudinally and transversely of the plaster boardythey will strengthen andreinforce it against cracking or breakingj either longi- 'tudinally' or transversely throughout the length of the ,entire board. Furthermore,
I if the nails for supporti'ngthe plaster board are driven through the twine, or even close wit, the twine will to a great'extent prevent the laster board from cracking or breaking a i'the point where thenails enter.
Furthermore, by the use of reinforcing strands of twine and thetop layer of gisbestos sand and cement, I'fam able to emplo materials in the plaster that are cheap and inexpensive and at the same time the ,completed .plastcr board will have great strength, and also a smooth, hard, surface. 4
