JOHN SCHUMACHER, 013 LOS ANGELES, CALIFORNIA.
BEENFORCED PLASTER BOARD.
Application filed November 4, 1924. Serial No. 747,795.
To all whom it may concern:
Be it known that I, JOHN SCHUMAOHER,
a citizen of the United States, and resident of Los Angeles, in the countyof Los Angeles, State of California, have invented new and useful Improvements in Reenforced Plaster Board, of which the following is a specification.
This invention relates to the general class of articles known as plaster board, plaster lath and the like and hereinafter is broadly referred to as laster board. The present invention pertalns particularly to that type of board having a cementitious body of slab form. Such articles during transit, installation in structures, and use thereafter are exposed to strains at the edges tending to crack, split and otherwise damage the same.
The objects of this invention are broadly to provide a board having a reenforced edge which is durable, economical, and efficient; and more specifically to provide a board having an edge reenforced longitudinally, laterally, and transversely.
These objects together with other objects and corresponding accomplishments are obtained by means of the embodiment of my invention illustrated in the accompanying drawings, in which:,
Fig. 1 is an edge view of a board constructed in accordance with my invention; Fig. 2 is a plan view of a fragment of the board, a portion of a covering sheet and the body being broken away to better show the reenforcement member; and Fig. 3 is a perspective view of a fragment of the reenforcement member.
The article shown herein as embodying the invention is a type or board in which plaster forms the body thereof and this body is enclosed on one or both opposite faces with the pliable sheets suchas paper. Referring more particularly to the drawing, 5 is the plaster body and 6 and 7 are paper sheets applied to opposite faces thereof and adhering thereto. The manner and means of makin such a board is well known in the art. Em" dded in the edges are reenforce ment strips preferably of paper and hereinafter more fully described.
Strips of paper 8 are embedded in the plaster body during manufacture. These strips are slit laterally as indicated b 9, and the slit portions bent upwardly to fbrm an echelon file or ridges or triangular tongues indicated by 10.
It will be observed by inspection of Figs.
1 and 2 that the body of the strip serves as a reenforcement longitudinally of the board. The ridges by reason of their position serve as a reenforcement of the board at the edge both transversely and laterally of the board, The construction is such as to effectively reenforce the edges in all directions. The reenforcement strip being made of paper will be suitably bound to the body of the board, and being light in weight, it is both durable and does not detract from the character of the board and the edge.
What I claim is:
1. A plaster board of the character described comprising a cementitious body a reenforcement strip embedded in the ct go and extending longitudinally thereof, said strip having portions protruding from its face transverse to the board, the planes of said portions inclining laterally of the length of the board.
2. A plaster board of the character described comprising acementitious body a reenforcement strip embedded in the edge and extendin longitudinally thereof, said strip having ridges protruding from its face and upset therefrom and extending transverse to said board.
3. A plaster board of the character described comprising a cementitious body, a rcenforcement strlp embedded in the edge and extending longitudinally thereof, said stri having ridges upset therefrom, exten ing transverse to the board and arranged in echelon formation.
4. A plaster board of the character described eomprising a cementitious body, a reenforoement strip of pliable material embedded in the edge'and extending longitudinally thereof, said strip being slit laterally therefrom with their planes arranged in 10 to form triangular tongues upset therefrom echelon formation so as to reenforce the so as to extend transversely of the board. board longitudinally, laterally and trans- 5. A plaster board of the character deversely, scribed comprising a cementitious, body a In witness that I claim the foregoing I reenforcement strip of pliable material emhave hereunto subscribed my name this 2lth 1 bedded in the edge thereof and extending day of October, 1924. longitudinally thereof, said strip being slit laterally to form triangular tongues upset JOHN SCHUMACHER.
