Patented Dec. 13, 1932 UNITED STATES renier JAMES MCLAUGHLIN, F GLEN COVE, N'VVl YORK REENFORCE ROD AND WALL :PLUG

Application filed June 15,

My present invention has reference to building structures and particularly to structures of brick and concrete, and my object is to embed at determined spaced intervals in the building construction metal plates which have means at the ends thereof for tying the same together, the said plates being formed with and provided at determined spaced intervals with casings for a molding block so that the said block has its outer edge CID arranged flush with the inner wall surface and whereby molding boards, studs or other plankings may be nailed to the block to materially assist in the molding of the concrete wall, as well as to provide a means for securing studs or battens to the inner face of the wall so that laths or the like may be secured to such battens.

A further object is the provision of a device for this purpose in which the casing of the improvement has a top that is yieldable so that the wooden block may be readily inserted in the casing and held therein by clips, the lower wall at the outer edge of the casing being formed with a bendable portion designed to afford a downwardly extending apron to contact with the inner face of the wall and thereby insure the proper position of the plate which carries the casing in the wall structure.

To the attainment of the foregoing and other objects which will present themselves the improvement also resides in certain other novel features of construction, combination and operative association of parts, one satisfactory embodiment of which is disclosed by the accompanying drawing.

In the drawing:

O Figure 1 is a horizontal sectional view through a wall structure provided with the improvement.

Figure 2 is an inner face view thereof.

Figure 3 is a perspective view of the improvement.

Figure 4 is an enlarged sectional view approximately on the line 4 4 of Figure 1.

Figure 5 is a plan view of the blank from which the casing is struck.

As disclosed by the drawing the improvement contemplates the employment of any 193i. serial No. 544,635.

desired number of metal plates 1. Each plate, at one of its ends, is formedv with an 'aperture 2, and at its other end with an upstandlng-stud 3. The studs of the respective plates are designed to be received in the apertures of the cooperating plates and whereby the plates will be sustained in parallelism and in interlocking engagement.

The plates are of desired lengths and each of the plates, at predetermined and equidistantly spaced intervals has'secured thereon the base 4 of a metal casing. The upper wall of each of the casings is extended at a downward angle from the rear wall 5, so that there is a substantially wedge-shaped pocket provided between the upper yand lower walls. The rear walls of the casings are indicated for distinction by the numeral 5 andfare arranged in a line with the inner edges of the plates l and the upper walls of the said casings are indicated by the numeral 6. The lower wall 4 is extended a suitable distance beyond the outer wall 6 and the said lower wal-l and its said extended portion adjacent to its edges is slitted to form outer bendable clips 7 and a central bendable plate in the nature of an apron 8. A wedge-shaped wooden block 9 is arranged in the casing, and thereafter the clips 7 are bent upwardly against the outer reduced face of the block 9 and over the top 6 of the casing. The central portion 8 of the bottom wall 4 of the casing is bent downwardly so that the same will be arranged flush with the inner face of the wall 10.

The casing construction permits of the ready insertion of the wooden block thereon, the said block being clamped in the casing by the bendable clips 7 and the apron contacting with the outer face of the wall limits the inward movement of the casing in such wall and consequently holds the plates 1 in proper longitudinal alinement. The outer reduced edge of the block is exposed so that molding boards or planking may be tacked f thereto when the improvement is employed in the construction of concrete walls, and likewise when such molding boards are removed studs or battings may be nailed to the blocks. It is, of course, to be understood that the casings and the respeetive series of plates l are arranged directly above each other throughout the length of the wall. The substantially wedge-shaped body of the casing having its widened end received in the wall structure prevents the accidental removal of the said casing when the same is embedded in either a concrete or a brick Wall. Nails may be readily driven into various parts of the exposed edge of the wedge block 9 and Withdrawn therefrom in an easy and eX- peditious manner. Should the driving of the nails into the block cause the splitting of the said block, this will only tend to force the top and bottom of the casing away from each other and to bunch the split block in the casing.

Having described the invention, I claim:

A plug for either a concrete or brick wall comprising a casing to be embedded in the wall, said casing being constructed from a single sheet of metal to afford a bottom, an inner end wall extending at a right angle from the bottom and a top which is of a less length than the bottom and which is arranged at a downward angle with respect to the bottom, a wed e-shaped block designed to be received in t e casing, bendable clips integrally formed on the corners of the bottom designed to be bent over the top and to hold the top a ainst the wedge block and for sustaining t e wedge block in the casing and said casing having its bottom, between the clips, formed with a depending apron to Contact with the outer face of the Wall to hold the plug in proper position in the wall structure.

In testimony whereof I afiiX my Signature.

JAMES MGLAUGHLIN.
