Nw. m H923. mmm H. A. CUMFER PLASTER RECEIVING BOARD File@ Jan. 23 1922 Patented Nov. 13 i923.

. STVEWA'RT, OF HUTCHINSON, KANSAS.
PLASTER-RECEIVING BOARD.
' .application filed January-23, 1922. ASerial No. 531,037'.
To all whom t may concern: p
, Be it known that L HARRY A. CUMFER, a citizen of Athe United States, residing-at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful improvements in Plaster-Receiving Boards, of which the following is a speciication. Y
This invention relates to plaster-receiving boards.
One of the objects of thev invention is to provide an inexpensive, strong, durable, and serviceable plaster-receiving board.
Another object isto providea plaster- .receiving board by makingit ofva single imperforate sheet of water and moisture resist ant material.
Another object is to make a plaster-receiving boardby forming a series of parallel ribs of a single sheet'and cementing parts of the sheet together in fashioning the ribs, land providing in the ribs meansfor keying the' plaster to the board.
@ther objects and advantages will hereinafter appear to persons skilled in the art from a Aconsideration ofthe following description when taken in conjunction with the drawings, wherein Fig. 1 is a plan view of the plastered wall with parts broken away showing part of the plaster-receivng board thereunder.
F ig. 2 is an enlarged section taken on line 2-2 of Fig. 1.
Fig. 3 is a view similar to Fig. 1, of a modied form of board.
Fig. t is anenlarged section taken on line 4--4 of Fig. 3. ln all the views the same reference characters are employed to indicate similar parts. rl`he plaster-receiving board is made of a single sheet 5, preferably of waterproof and moisture-proof material such, for example, as a fibrous sheet saturated with ,hot asphalt and preferably coated with the sameribs and cemented to the same by the hot asphalt 13 and by'application of pressure to the parts. When the cementitious material has cooled the parts will adhere firmly, together and the cement is not soluble in water and'therefore any dampness that 60 may penetrate to the joints between the parts 7 and 8 will not cause them to spread apart. The ribs 10 are parallel and the overlying heads form means for keying the plaster between adjacent ribs, as clearly ,65 shown in Figs. 1 and 2. The part 111, between adjacent ribs, is suii'iciently flexible to permit the structure to be rolled upon a reel in which compacted condition it may be advantageously stored or prepared 'for 70 shipment.
- ln the modifications shown in Figs. 3 and 4t the head l() ofthe ribs 6 is left otlZ and holes 16 and 1,7 are madethru the parts .7 and 8 thru which the plaster will key. 75
Inneither case are the ribs G or 10 of height sufficient to. extend entirely thru'to plasterl, when the same is applied to the plaster-receiving board. `When applying the plaster-receiving board to a supporting structure, nails are passedthru the parts 14: that are located between the ribs.
When the plaster receiving board is applied to a studded wall, thev ribs Gand l0- are preferably placed at right angles to the longest axis of the studs, so that the ribs will stil'fen the structure when supported by the studs.
The cementing effect produced by the hot Vasphalt will sutliciently hold the parts 7 90 and 8 together andafter the nails have been placed thru the parts v14: the cement is thus relieved, in a large measure,l of st-ressA by the supporting effect of the nails.
The sheet 5 is imperforate and water-re- 95 sistant and therefore moisture, wind or water cannot pass`thruthe plastered wall and appear inside'on`the plastered surface. Thesheet is also a poor conductor of heat and therefore there will be very 109 little, if any, condensation of moisture on the inner surface of the l,plastered wall as a result of frost penetration.
Having described my invention what l claim as new and desire to secure by Let- N5 ters Patent, is A 1. A plaster-receiving board comprising a single' sheet uniformly coated throaghout with anl Aadhesive plastic material and crimped to form a series of parallel, laterally extending, integral, plaster-keying ribs,
the sides fof the ribs Acemented together by the contacting coating.
2. A plaster-receiving board comprisinga single sheet uniformly coated throughout with an adhesive plastic material and crimped to'form a series' of parallel, laterally extending, headed ribs, the sides of the ribs cemented together and the parts of theheads cemented together by the contacting coating.
. A' plaster-receiving board comprising In testimony vWhereofiil `hereunto subl20` scribed my name.
