G. H. ELLIS WALL CONSTRUCTION Filed May 21, 1934 Patented Apr. 23, 1935 PATENT OFFICE WALL CONSTRUCTION George H. Ellis, St. Paul, Minn, assignor to'The Insulite Gompany, Minneapolis, Minn, a corporation of esota Application May 21, 1934, Serial No. 726,654

This invention relates to improvement in building construction, particularly to the method of applying facing elements or board in the construction of walls of buildings. The method may be applied in relation to studdings or to the flooring stringers and the facings are ordinarily covered with plaster, cement or stucco. The invention also includes means for decreasing the heat losses at the joints and means for reenforcing the joints and assisting in bonding the plaster.

This application is an improvement in part on my co-pending application Serial #623,335, filed July 19, 1932.

Features of the invention include: the use of fibrous elements in forming wall structures; the wall structure itself; the -reenforcing devices themselves and their methods and means of attachment and generally to all details of construction of the reenforcing elements and means for connecting them.

Other and additional objects of the invention will be set forth. in the description and the drawing which form a part of this application. In the drawing:

25 Fig. 1 is a view showing one embodiment of my invention as applied in the formation of a wall.

Fig. 2 is an enlarged section showing a reenforcing means and an interlocked joint.

Fig. 3 is a sectional vlew'showing another form of reenforcing means.

Fig. 4 is a perspective view of a looped reenforcfing' means.

Fig. 5 is a View ofa fiat reenforcing means showing the form as stamped from a sheet of material.

Figures 6, 7 and 8 are modified forms of reenforcing means.

Figure 9 is a view of the prongs which are adapted to be driven into the material.

Heretofore it has been customary to reenforce the joint and assist in bonding the plaster by providing or cutting away a portion of the tongue member so as to provide a groove that increases the depth of the plaster in the region of the joint.

45 This means of reenforcing and assistance in bonding the plaster decreases the insulation value at the joints. and is not altogether successful in providing proper bonding of the plaster.

According to my invention the insulation value at the joint is greatly increased and practically the same as that of any other portion of the wall and in addition to this the joint is reenforced' and the reenforcing means acting as a plaster ground and assists in bonding the plaster.

In the drawing the numeral 10 indicates studthe dings against which are laid slabs of fibrous material H, suitable as a plaster. base. This material is secured to the studding by means of suitable fastening devices 52. The slabs may be of any desired length and width but generally the length of slabs used for this purpose is about 48 and the width about 18''. The long dimension of the board is generally laid so as to be transversed to the studding and the abutting ends of the contiguous boards of the horizontal 10 rows takes place on the studdings and these vertical joints need not be over-lapped but if desired they can be so constructed.

The slabs are formed and laid to provide a ship lapped horizontal longitudinal joint, generally in- 15 dicated at i3, see Figure 2 and for this purpose the opposite end of each slab i! is cut out respectively as at it to provide a recess or notch at opposite longitudinal edges. Although in this in stance each element M is notched there is no 20 intention to limit the shape of the longitudinal elements, just so they are formed to provide an over-lapped, and/or inter-locked joint which will not decrease the insulation value at such joints.

It is an important object of this invention as before stated to increase the insulation value at the joints and to reenforce such joints and assist in bonding the plaster securely to such plaster receiving base.

When walls are constructed in accordance with 30 this invention there is no unevenness in such walls and the plaster will be uniform in thickness as the reenforcing means requires a plaster to be sufficiently thick to cover them and thus makes it impossible to skin the plaster.

A joint that does not have a. tendency to open due to pressure while applying the plaster is shown in Figures 2' and 3 but it is to be understood that the invention is not limited to this type of joint but includes any joint that prevents the insulating value from being decreased.

One form of the reenforcing means hasthe form of a looped structure formed by bending a single piece of wire upon itself to provide arms l5 which converge at the open ends outwardly and the terminal portions are bent'in a direction substantially parallel with each other or the terminal portions are bent toward the closed end of the loop. The tip of each terminal portion is bent in a direction substantially perpendicular to the plane of the arms and these tips are. tapered to provide prongs l6, adapted to be driven into the material to which the device is secured. The prongs IG are driven into the sheet at a point between the open end and the edge of the sheet 5 to which it is attached.- The prongs thus arranged prevents the arms from swinging to and fro and they pass entirely through the sheet or only a part of the way through. The loop is secured to a sheet in such a manner that one end thereof extends outwardly beyond the edge of the sheet and over the edge of a like sheet which cooperates with the first mentioned sheet in forming an air-tight joint.

Figure 7 discloses another form of reenforcing means which is stamped or cut from a suitable sheet of material. The body ll of the reenforcing means may be-of any desired shape'but preferably that shown in Figure 7. When the "reenforcing means it stamped out portions are removed and the body is split along the edges at one end. The prong like

members

18 and 19 are bent in a direction substantially perpendicular to the body and act as a means for securing the reenforcing means to the sheet and to prevent swinging about the prong 20 as a center. The openings formed in the body assist in bonding the plastered material.

In Figure 8 is disclosed a modified form of a wire loop that has the arms twisted to form an eye 2| through which a securing means is adapted to pass. This form of wire loop is used in substantially the same manner as the wire loop previously described.

Figures 5 and 6 disclose modified forms of reenforcing means composed oi body members 22 and 22' having openings 23 in the body of the reenforcing means. In Figure 5 additional openings are formed near one end for the reception of securing means. This means may be nails or any other suitable securing means.

The modified form shown in Figure 6 has one end 25 bent at substantially right angles to the main body and shaped to act as securing means for fastening to the sheet and a prong 26 extends from the body to act as means for preventing the reenforcing means from swinging about the prong 25 as a center.

In Figure 1 is shown a modified form which may be considered in the shape of letter s. The body portion indicated at 26' and secured to the sheet II by prong Ii. This'type is used as indicated in Figure 1 at 21.

It is to be understood that the reenforcing means may be used on either side of the joint depending on whether the finished wall is to be plastered or not.

For the purpose of this application there has been set forth certain structures and certain methods of using the same but it is to be understood that they are here presented for illustrated purposes only and are not to be accorded any interpretation such as might have the effect of limiting what is claimed as the invention short of its true and comprehensive scope in the art.
