Specification of Letters Patent.
Patented Dec. 22, 191d.
Application filed January 8, 1913. Serial No. 740,813.
metallic reinforcing strips for plaster walls,
and more particularly strips for reinforcing the weaker portions of the plastering, such as at corners or edges. In order that strips of this character may be conveniently embedded in the plastering, it is desirable to,
provide perforations therein, through which the plaster may be forced at the time it is applied to the Wall. I have ascertained that the pressure which is applied to the strip by the plasterer in attempting to force the plaster through such apertures, and also in smoothing the surface, frequently acts to bend or distort the strips, and, also, that with prior constructions it has been deemed inexpedient to make these apertures of sufficient size to permit the plaster to be forced therethrough in an effective manner, or to an 'appreciable extent. i
The object of my invention is toprovidc an improved form; of metallic reinforcing strip having apertures so arranged and of suilicient size to permit the plaster to be forced therethrough readily, and in which the loss in strength of the strip, by reason of the formation of the apertures, is compensated for, and the stiffness andrigidity of the strip, in resisting lateral bending, is increased. I accomplish this object by the means shown in the accompanying drawing, in which,
Figure l is a cross-sectional view of a reinforcing strip in position in the plastering. Fig. 2 is a plan view of the strip. Fig. 3 is a sectional View on the line 3-8 of Fig. 2.
Fig. 4 is an enlarged detail View of a porthe space to be occupied by the plaster. A
portion a is extended obliquely from the base portion a, which is provided with a rolled edge a for the purpose of stiffening it and also to produce a rounded or finished edge which is usually exposed.
A series of elongated apertures a are formed in the portion a said apertures being madequite long to admit of the plaster being readily forced therethrough. The intermediate portions a between said apertures, are bent or twisted obliquely inward from the end of one aperture to theadjacent end of the next aperture, so as to provide an inclined surface leading from one to the other. The oblique formation of said intermediate portions or aids materially in stiffening the strip, to hold it against lateral bending, so that when pressure is applied there-against, during the operation of applying the plaster or of smoothing the same, it will not be bent inward, but will be held in the desired position, as shown in Fig. 1. This is of considerable importance when the strip isemployed as a corner reinforcement as the location of the corner can be correctly determined and the plaster applied in such manner as to present a truly vertical surface, otherwise the surface may be in clined, which is objectionable. The oblique portion a also acts to deflect the plastering into the apertures (1 so that the space in the rear of the strip will be. readily filled, and the pressure on both sides of the strip will be equalized.
1 claim A metallic reinforcement for a plaster wall, consisting of a metal strip formed to provide a flat portion and a lower angularly related portion, said latter portion being designed to be wholly embedded in the plaster and formed with a series of apertures arranged in longitudinal alinement, the portions intermediate the apertures being bent into distinct angular relation in a horizontal plane with the remainder of the perforated section, whereby the similar end portions of each aperture are disposed inwardly beyond the opposing end portion, as and for the purposes stated.
In testimony whereof, I'have signed my name to this specification, in the presence of two subscribing witnesses.
