Patented Ed, 1932 GEORGE lEl. ELLIS, OF ST. PAUL, MHHESOTA, AIGNOR TO THE INSULI'I'E COMPANY,
OE at i EAPOLIS, MINNESOTA, A EPORATION OF MINNESOTA BUILDING Application filed July 9,
constructed there rom, said composition,
5 boards being adapted for application either inside or outside of the studding or floor joists, and receiving coatings of plaster, cement or stucco.
An object of the present invention is to provide a composition board having its opposite edges corner beveled in a manner to provide longitudinal depressions between contiguous boards, when secured to a support and abuttingly engaged, so that when plaster or other coating material is applied to the surfaces of the boards, such material will be thicker in the region of the joint, thus increasing its strength and reducing to a minimum the possibility of the plaster cracking, as aresult of expansion and contraction of the composition boards, when subjected to moisture, as when plaster is applied to the surfaces thereof.
, A further and more specific object of the invention is to provide a composition or fiber board having one edge beveled across the thickness of the board, and having its opposite edge beveled at both corners to provide a comparatively sharp edge lying adjacent the medial plane of the board, and adapted to cooperate with the support to which the board is secured, to provide a so-called socket adapted to receive the V-shaped or beveled edge of the adjacent board to provide a temporary support therefor, before nailing it to the main support such as the usual studding.
The particular object of the invention therefore is to provide an improved composition or fibre board adapted for use in buildings and like structures, to provide a base for plaster and other material, and having means for increasing the thickness of the plaster at the joints of contiguous boards, the edges of the boards also being adapted for over-lapping engagement. The present application" relates generally to the same subject-matter as that of my Patent Number 1,752,787 of August 27 1929, the application for which was copending herewith.
1928. Serial No. 291,355.
Other objects of the invention will appear from the following description and accompanying drawings and will be pointed out in the annexed claims.
In'the accompanying drawings, there has been disclosed a structure designed to carry out the various objects of the invention, but it is to be understood that the invention is not confined to the exact features shown as various changes may be made within the scope of the claims which follow.
In the accompanying drawings forming part of this specification;
Figure 1 is a perspective view showing the improved composition boards embodied in a. wall structure;
Figure 2 is a vertical sectional view of Figure 1;
Figure 3 is a perspective view of aboard;
Figure 4 is an enlarged detail sectional view showing the overlapping engagement of the edges of contiguous boards and showing the depression provided for the reception of,
preferably rectangular in form and having its' opposite edges beveled as shown. The lower edge of each board is provided with a beveled edge 3 extending through the thickness of the board as clearly shown in Figure 4. The upper edge of the board has both corners beveled to provide inclined faces 4 and 5, the latter face being relatively narrower than the inclined face 4. The faces 3, 4, and 5 are preferably arranged or cut at the same angle so that the beveled edge of one board may be seated against the relatively shorter beveled edge. 5 of an adjacent board, as shown in Figures 2 and 4. The boards are adapted to be secured to a suitable support,
the sheet against the studding while nailing it thereto. The beveled edge 5 also provides means. for supporting one edge of the board when securing it to a ceiling, as indicated by the dotted lines in Figure 2. As here shown, the beveled edge of the lower side of the board, when viewed as shown in Figure 3, is inserted between the beveled face 5 and the ceiling joists 8, thereby holding one edge of the board while the mechanic raises the opposite end of the board and secures it to the joist. The particular arrangement of the beveled faces 3, 4, and 5, therefore, provide means to facilitate the mounting of the boards upon their supports.
The beveled faces 3 and 4 co-operate to provide longitudinal recesses or depressions 9, extending lengthwise of the boards and adapted to receive plaster or other coating material applied to the surfaces of the boards, as shown in Figure 4. These V-shaped de pressions cause the plaster to be thicker in the region of the joint so as to prevent the plaster from cracking or fracturing, due to contraction of the boards. When the plaster is applied to the surfaces of the boards, the latter absorbs considerable moisture from the plaster, causing them to expand more or less, and as the boards become dry, they contract to a certain degree, causing the plaster to crack at the joints, unless suitably rein forced. In the drawings, I have shown the hori zontal edges of the boards beveled only but it is to be understood that, if desired, the end edges thereof may be similarly beveled without departing from the scope of the lnvention.
Referring to Figure 4, it will be seen that the lapping of the joints in the manner shown in the figure allows for relatively free expansion and contraction in a direction across the joint, due to the sliding engagement of the inclined or beveled surfaces respectively of the front of one board against the inclined surface at the back of the other.
Another advantage in beveling, is that no special tool is needed (as in rabbeting) and the control of the tool is easier, when cuttlng a bevel extending from one face side to the other, and when forming a substantially knife-like edge which lies at a point intermediately of the faces of the slab, and particularly when the bevel angle is the same in.
all cases.
I claim as my invention:
1. A board having one face marginally beveled to provide a knife edge disposed in the plane of the opposite face, and having its opposite margin double beveled to provide a knife edge lying at a point between the faces.
2. A board having one face marginally beveled to provide a knife edge disposed in the plane of the opposite face, and having its opposite margin double beveled to provide a knife edge lying at a point between the faces, the angular relation of the beveled faces to the faces of the board being the same for all I bevels.
3. A support, a plurality of slabs of composition fiber arranged on the support and being marginally beveled, and the bevels being overlapped to slide upon one another and allow slippage of one panel upon the other during expansion or contraction, and arranged to provide a depression on the out-er faces of the slabs, extending toward across and lengthwise of the joint, so that when plaster is applied to the outer surface it will be thicker in the region of the joint.
4. A support, a plurality of slabs arranged on the support and being marginally beveled, and the bevels being overlapped to slide upon one another and allow slippage of one panel upon the other during expansion or contraction, and arranged to provide a depression on the outer faces of the slabs extending toward across and lengthwise of the joint, so that when plaster is applied to the outer surface it will be thicker in the region of the joint, the beveling providing edges which are substantially knife-like to so weaken the material as to allow it to be crushed during expansion.
5. A support, a plurality of slabs arranged on the support and having opposite edges beveled atthe same angle in a manner to form inclined planes which cooperate with adjacent co-overlapped slabs to allow slippage of one panel upon the other during expansion or contraction, one of the overlapped members being beveled in two directions, and one of the bevels cooperating with the bevel of the co-overlapped slab to form a depression extending across and lengthwise of the joint.
6. A support, a plurality of slabs arranged on the support and having marginal portions beveled and overlapped to form an expansion joint, the beveled portion of one slab extending rearwardly of the other, and the beveled portions of the adjacent slabs forming a depression extending toward and across and lengthwise of the joint, knife-like edges being therefore formed at each of opposite substantially parallel edges facilitating fracture at the-edge.
7.. A support, a plurality of slabs arranged on the support and having-marginal portions beveled and overlapped to form an expansion joint, the beveled portion of one slab extending rearwardly of the other and the beveled portions of the adjacent slabs forming a depression extending toward and across and lengthwise of the joint, knife-like edges 3 being formed to facilitate fracture.
8. In combination with a support, slabs secured to the support and having beveled faces overlapped and engaged to form an expansible joint, each slab being additionally beveled adjacent the joint, and the bevels' of adjacent slabs cooperating to provide for an increased depth of plaster in the region of the overlap.-
9. In combination with a' support, slabs secured to the support and having beveled faces overlapped and engaged to form an expansible joint, each slab being additionally beveled adjacent the joint and the bevels of adjacent slabs cooperating to provide for an increased depth of plaster in the region of the overlap the formation to provide for this increased depth of plaster being discontinuous.
