:BLASTER-RECEIVIING BOARD.
original Yappncaiimi ined August 17, 1922, serial No. 582,344. Divided and 1926. serial No. 99,498.
This invention relates to plaster-.receiving board, and is a division of an earher ap l1- cation filed by me under dat of August 1 th,
1922, Serial No. 582,344.
One of the objects of the invention is to improve the construction of plaster-receiv- .ing boards of the type made of two associated sheets, of which one is imperf0rate by providing a structure that may conveniently be made by a machine from a constantly moving strip or sheet of suitable material.
Another object is to provide improved means for securing the sheets together and to the supporting wall.
A further object is to providel pockets for plaster between the two sheets by pressin parts of oneor both sheets out of norma planes and cementing the displaced parts to the inner surface' `of the other sheet Within the pockets or channels.
Another object is to provide a structure, of the class described, in which alternate channels are not so wide as the intermediate, plaster-containing channels.
Another object is to provide a plasterreceiving structure made of two united sheets, the outer sheet having perforate channels to receive plaster, the inner Sheet having an inclosed imperforate channel, like vwalls of lthe channels being cemented together.
Other objects and advantages of the invention will hereinafter 'appear from a consideration of the following description, when taken in conjunction with the drawings, wherein Fig. 1 is a cross sectional v1ew taken on line 1--1 of Fig. 2.
Fig. 2 is a plan view'of Fig. 1 with certain parts in section.
Fig. 3 is a section taken on l1ne 3 3 of Fig. 4 showing a variation of my invention. Fig. 4 is a reduced plan view of Fig. 3. Fig. 5 is a similar view of a similar structure.
In all the views the same reference characters may be employed to indicatel similar arts. p The structure is made of two sheets of suitable material having composite pockets to receive plaster that may be applied to its outer surface, provided by dis lacement of portions of either sheet, the dlsplaced porthis application iled April 3,
tions of one sheet being cementedor otherwith a water-resistant such as asphaltum or a compound thereof and coated on both sides with a similar material 6, more or less plastic when warm and which forms a strong cement when cold. r1`he lower or base sheet 7 .is imperforate. rIhe u per or outer sheet 8 is formed into channe s 9 and 10. The alternate` channels r9 may be wider than the intermediate channels 10.
The smaller channels are utilized to nai both sheets to the supporting wall 11.
Contacting portions of the two sheets are l cemented together at 13.
In Figs. 1 and 2 the outer sheet 8 is slotted longitudinally at intervals to provide plaster rece1v1ng openings and thetongues 12l are bent inwardly and cemented to the upper surface of the sheet 7. ,In Figs. 3 and t the slits are made so as to divide the tongues to provide portions 20 which are parallel with the base sheet and cemented thereto. affords a larger surface contact than the form shown in Fig. 1. The parts 12a form strengthening projections extending from one sheet and cemented to thel other sheet Within the plaster-receiving channels 9.
The contacting surfaces of the sheets may be held together while the asphaltum is hot and, while'so held, a cooling agent such as water or the like may be applied before they are released, whereupon the surfaces will be firmly held together by the relatively cold plastic.
1n Fig. 4 the slits 21 divide the projections into two parallel tongues each equal to the entire Width of the opening madeby their displacement' from the bottom sheet, while the slit 22 Fig. 5 produces two tongues, each about one-half the length of the opening. The-openings are made in the outer wall of the closed channel in each case and through these openings plaster will pass into the interior ot the channels 9.
I claim as my invention:
l. A plaster receiving board comprising a base sheet and an overlying sheetl having alternate inwardly and outwardly extending self-supporting channels substantially rectangular in shape, the crest of the inwardly extending channel being perforated to provide plaster keying means, the incised portions formed 'by the perforations being depended downwardly and atiixed to the base sheet.
2. Corrugated board comprising two sheets, one sheet formed into a series ot alternate channels and ridges, having surfaces parallel to the other sheet, said channels xedly attached to the other sheet, 'the ridges having incisions therein, through which a plastic substance applied to the sheet keys is lixed thereto, parts of the incised portions being attached to the other sheet.
3. A corrugated board comprising two sheets, a base sheet and an overlying sheet, the latter formed into a series of alternate channels and ridges, the channels iXedly united to the base sheet, the ridges having incisions therein adapted to produceapertures through which to key a plastic substance 'applied thereto, free portions produced by said in# cisions depressed and xedly adhering to the base sheet.
4. Corrugated board includingabase sheet and an overlying sheet, the latter formed into a series of alternate channels and ridges, portions ot said channels being xedly attached to the other sheet, the ridges having incisions therein, freepgrtions produced by said incisions being firmly attached to the surface of the other sheet.
5. Corrugated board including a base sheet and an overlying sheet, the latter formed into a series of alternate channels and rid es, said channels fixedly attached to the ot er sheet, the ridges having incisions therein, through which a plastic substance applied to the sheet may be keyed, tree portions pro# duced by said incisions being rmly attached to the surface of the other sheet.
