REENFORCED-EDGE PLASTER BOARD.
Application This invention relates to a plaster board or like article comprising a slab-like body of cementitious material. Such articles are subjected to much handling during manufacture, storage, distribution and in the process of building. During the handling, the board is frequently damaged at theedges by chipping, fracturing, abrasion, and in other Ways. It is therefore desirable to have a board With an edge constructed to efiectively Withstand such usage.
The present invention has for its primary object the provision of a board reenforced at its edges by a stratum of cementitious material and strips of pliable material. An-
other object of this invention is to provide a board of the character described which is reenforced at the edges by inserts consisting of strips of plaster board themselves comprising a plastic body and covering sheets of paper.
The accomplishment of these objects together with other objects is obtained by means of my invent-ionillustrated in the ac companying drawing, in Which:
Fig. 1 is a perspective view of a fragment of board and Fig. 2 is a transverse section through an edge on an enlarged scale.
The major portion of the board is formed in the manner and of the material nowcommonly used. The cementitious body 5 is preferably formed of plaster and is covered on the faces by sheets of paper 6 and 7.
filed November 4, 1924, Serial No. 747,796. Renewed November 23, 1927.
This paper is bound to the board. Embedded in the body of the board at the edges are inserts A, being in themselves strips of thin plaster board. Thus, an insert as shown in Fig. 2 comprises a body 8 of plaster and covering sheets 9 and 10. The plaster body 8 may be of a different material than the body 5. This material may be of a harder plaster, it may be coarser or differ in any other Ways found desirable.
It is obvious tudinally extending strips of paper which serve as a reenforcement. The body8 of the'insert forms a stratum which may be of selected material for reenforcement purposes. The board may be manufactured 1n any desired Way, it being suggested that the inserts A be initially formed and embedded in the plaster body as the board proper is formed, the insert being in a green state.
What I claim is:
An article of the class described comprising a cementitious body provided with a longitudinally extending insert comprising pliable sheets With a cementitious core interposed therebetween and bound thereto, said core being of material differing from said body.
that each edge has two longi-.
In Witness'that I claim the foregoing 1' have hereunto subscribed my name this 27th day of October, 1924.
JOHN SCHUMAOHER.
