ALozo B. Toux. or oxlHULeiiEr, espanola. A v i I Application led December 90, 1924. Serial No. 757,177.
To all 'whom it may concern:
Be i known that I, ALoNzo Bf-TURK, a
v citizen of the United States,l and a resident of Okinulgee, in the county of Okmulgee and State of Oklahoma, have invented cer-4 tain new and useful Improvements in Plaster Boards, ofY which the following lis a specification. V
This invention relates to building material and more particularly to plaster boards as a ground for the interior and exterior walls.
An object of the invention is the provision of aplaster board having a plurality of vo-operative locking devices for maintaining a plaster or stucco finishen the board.
A furtherbbject of the invention is the provision of undercut grooves and raised ribs incorporated in a .plaster boardv for respectively locking a surface coating to the board and for forming a. directional means' -a modified form for interi-or walls.
Figure 3 is a detail sectional View illustratin lan edge reinforcement for the iniprove board. v
In the drawing the numeral 1 designates the main body of the Iboard, which board is formed of 'a composition of gypsum and woodfibre or any material found suitable for the purpose. The drawing clearly illustrates that the' outer side of the lboard is formed with a plurality of spaced approximately parallel undercut grooves 3 for the reception of a portion of the final or skim coat designated by the num'eral 9. It is thus seen that the finall or skim coat 9 is intimately joined with the board 1 to resist cracking or peeling as the result of changes in weather conditions.
Figure 3 plainly illustrates that a coarse l layer of burlap 6 1s stretched across the outer surface of the board 1 and spans the undercut grooves 3 so that Iit is necessa for the plaster or stucco 9 to be forced through In the accompanying drawing forming a the burlap to enter .and firmly` seat in the grooves 3. By reason of this arrangment the c oarse burlap is extended through substan` `tial portions of the coat 9 to assist the undarcut grooves in holding the coat firmly in p ace.
The vouter side of the board 1 may be provided at intervals of eight inches, more--or less with approximately parallelv raised ribs L 4 wliichact asa furring means and a gauge to assist the plasterer 1n obtaining a final coating of a uniform thickness. Figure 2 plain] illustrates that ,theco'arse burlap 6 exten s about'the undercut ri'b 4 and mayl 'i be joined in any suitable manner with the undercut side lwalls of the same.
`In case the improved plaster board is used for exterior work as illustrated in Figure 1, the raised ribs 4 will provide a spacing means for an open work metallic rein forcing member 7. After a wall has been by the application of a plurality.
forme of the improved plaster boards to the studs the open work metallic reinforcing element 7 for the coating' of laster is applied and anchored at suitab boards. When the final coat 9 is applied in a plastic state a portion of the same will ev intervals to the,
easily pass through the open reinforcing element 7 and when' forced through the burlap 6 will enter the grooves 3 and firmlyk atah 'itself a the body 1. i
' In summarizing 1t will be seen that ther are three separate means to hold the final coat in position. The undercut ooves 3 constitute the first and possibly t e major means to hold the final coat in lace. The coarse burlap 6 forms the secon means for holding the final coatl in placewhile the reinforcing element 7 forms the third meansn for holding the final coat in place.'
Figure 3 illustrates that the edge portions of the boards may be slightly 's aced when applied to the studdin v25 an of the boards are bevele to provide a groove for the reception of a portion of the -plaster. Therefore, when the final coat is applied lthe plaster which enters the space bef' tween the edges of the boards as clearly shown in Figure 3 will form a key by which the final coat is further held in place.
Another important feature of thel invention is illustrated in Figure 3 wherein it is shown that the board 1 may be backed with building or other paper30 of a suitable the edges wei ht and the paper or backing 30 is ex. tened about the beveled edges o the board as shown in Figure 3. This figure also 1llustrates that the edge portion of the backing 30 uis extended over the outer surface of the board a substantial distance into overla ping relation with the adjacent portion ofP the coarse burlap. In fact, the edge portion of the coarse burla is embedded in a cementitious coating applied to said surcomprisin face may be forced through the burlap to fill the grooves.
2. A building board for wall constructlon spaced un ercut grooves at one surface and a burlap of coarse mesh stretched across the surface and covering the grooves ywhereby a cementitious coating applied to said surface must be forced through the burlap to fill the grooves, and ribs on the application surface.
3. A building board for wall construction comprising' a composition base having spaced undercut grooves at one surface and a burlap of coarse mesh stretched across the surface and'covering` the grooves whereby a cementitious coating applied to said surface must be forced through the burlap to fill the rooves, and ribs having undercut sides, t e burlap covering said ribs in close contact. e
4. A building board for wall construction comprising a composition base havin spaced undercut grooves at one surface an a burlap hof coarse mesh stretched acro the surface and covering the grooves whereby a cementitious coating applied to said surface must be forced through the burlap to 'fill the grooves, ribs on the application surface, and a coarse mesh wire screen sup-. ported in spaced relation with Said surface of the board by the ribs.
5. A building board for wall construction comprising a composition base having spaced undercut grooves at one surface and a burlap of coarse mesh stretched across.
the surface and covering the grooves whereby a cementitious coating applied to said Surface must be forced through `the burla to fill the grooves, and a paper cemente to a surface of the board. v
6. A wall board comprising a body, burlody 1 and the a composition base having lap applied to the outer side of the body andhaving its ed e portion embedded in the body,l and a bac 'n extended about the edge of the body an into overlappin engagement with the ledge portiono the .applied to the outer side of the body an having its edge portion embedded in the body, and a backing extended about the edge of the body and into overlap ing engagement with the edge portion o the burlap, a portion` of the body being extended through the 'edge portion of the burlap and united with the adjacent portion of the backing, the edges of the body being beveled. s l l 9. A wall board comprising a body, burlap applied to the outer side of the body and having its edge portion embedded in the body, and a backin edge ofthe bod agement with t e edge portion o the bur a a portion of the body being extended throu h the ed e portion of the burla and unite with t e adjacent portion, o thie backing, the outer sideof said body-being provided with grooves spannedby said burextended about the an into overlapping en- 10. A plaster board comprising a body, a i
layer of coarse burlap applied to the outer side of the body and having its edge portion embedded in the adjacent portion of the body, and a reinforcing element for thev edge of the body4 extended `about the outer surface of the body and -into overlapping engagement with said burlap, the material forming said body being forced through the edge portion of said burlap into bonding engagement with the reinforcing element.
