Oct. 18, 1932. E L. BENEDICT I REENFORCING FABRIC Filed May 24. 1930 INVENTQR Patented Oct. 18', 1932 unite STATES {PATENT OFFICE! EDWARD L. BENEDICT, OF PITTSBUBGH, PENNSYLVANIA, ASSIGNOR TO PITTSBURGH STEEL COMPANY, OF" PETTSBUBGH, PENNSYLVANIA, A CORPORATION OF PENNSYL- VANIA nnnnroncmernnmc Application filed May 24,

10, of in a building.

Another object of my invention is to provide a fabric structure of such form that it will have the required stiffness, even though the mesh be composed of relatively small gauge Wire.

Another object of my invention is to provide means for so holding a backing sheet and a wire mesh in unitary relation that the backing sh et is not likely to slip relative to the mesh, and thus result in excessive slack in the sheet at some points relative to certain other points.

Another object of my invention is to provide a stiffening member of generally channel form in cross section, and means for so holding it in the mesh that it may be of very light material, and nevertheless prevented from flattening or collapsing under pressures that would ordinarily cause the deformation of light weight channel members.

A further object of my invention is to provide a fabric structure wherein perforations formed in the backing sheet incidental to the attachment thereof to the mesh are sub .stantially completely closed by retaining is a rear view of the structure of Fig. 1, and v Fig. 5 is a sectional view of the fabric structure on an enlarged scale.

The structure consists of a backing or form sheet 6 in front of which is placed a wire 1930; Serial No. 455,325.

mesh'composed of What for convenience I will term strand wires 7 and stay Wires 8, and retaining bars 9 for holding the backing sheet and the wire tion.

The wires 7 and 8 are welded or otherwise i secured together at their points of intersection, and the wires Shave rearWardly-extending bends 10 that project through holes in the backing sheet 6, the bars 9 being slid into position in such manner that they lie within the bends 10, and their forward edges abut against the rear side of the sheet 6, thus locking the backing sheet. and the wire in unitary relation,

The fabric structures are made in sheets or rolls of convenient size and are intended to be applied to studding or other suitable framework. Plastic material 11 V such as stucco, plaster, or the like may then be applied to imbed the reinforcing wires or rods 7- and 8, the backingsheet 6 servingas'a form to prevent the plaster from falling away at' the rear side of the mesh. This backing sheet may be of building paper, extremely fine wire mesh or screen, or of water-proof sheet material, or the like.

The retaining bars 9 are of V form in cross section and snugly fit the bends 10 so that they are accurately maintained in position with 1 theiredges abutting the rear side of the sheet 6. Slit-like openings of considerable length in the sheet 6 are required, to permit the bends 10 to be passed through the paper, but the width of the bars 9 is such that the openings are substantially completely closed,'as shown more clearly in Fig. 5, when the parts are -assembled, thus providing for substantially complete. support for the plastic material "throughout the face of the sheet.

It will be understood that the'bends 10 may be of various other shapes, and that the bars 9 instead of being of angular form in cross section maybe of conventional channel form, or flat. In the case of fiat bars, the structure would not have as great stiffness, but said bars would serve to close the perforations through which the bends 10 extend.

The channel members 9 are not onlyv supported by the bends 10 in proper alinement mesh mesh in assembled relawith respect to the backing sheet, but are physically supported by said bends against deformation or flattening, thus permitting the channels to be made of lighter material than would be the case if they were merely attached: to the structure by clips or other holding members.

Furthermore, the bends 10 are an integral part of the wire mesh, so that the bars 9 are. held against, slipping transversely on the rear of the sheet 6, and the sheet itself, in engaging the edges of the bars 9, is thereby better held against slipping relative to the mesh,

than if a round bar were substituted for the channel member 9. It is important to hold the sheet againstslippi'ng relative to the mesh since in such event it would be so slack at some points as to require an excessive amount of plaster in order .to imbed the mesh and at other points would lie too tightly against the mesh to permit proper imbedment of the mesh by'plaster at those points.

I claim as my invention 2- 1. Fabric structure comprising mesh formed of wire-like members secured together at their points of intersection andhaving rearwardly-extending bends, a backing sheet having elongated openings through which said bends extend, and a retaining bar of U-form in cross-section, disposed to the rear of said sheet and lying Within said bends, the edges of the said bar abutting the rear side of the sheet, and the sides of the bar snugly fitting the said bends.

2. Fabric structure comprising mesh formed of wire-like members secured together at their points of intersection, and having rearwardly-eXten-ding bends, a backing sheet having elongated openings through which said bends extend, and a retaining bar of generally channel form in cross section having its edges abutting the rear side of said sheet and its edges snugly fitting within said bends.

, In testimony whereof, I" the said EDWARD L. BENEDICT have hereunto set my hand.
