WALL AND FLGOR PLUG.

Application filed August 22, 1922. Serial'fo. 588,500.

To all whom t may concern. Be it-'lmown that I, SAMUEL W. ROTH- noon, a citizen of the United States, and a resident of the city of New York, county a of Queens, andtate 'of New York, have invented a new and useful Improvement invention, reference is to be had to the accompanying drawings, forming a part hereof, in whichf Figure 1 is a plan view of a wall plug embodying my invention. Y g Figure 2 is a front elevation of the same. Figure 3 is a sectional view taken on the line 3 3 of Figure 1, looking inthe direction of the arrows;

Figure 4 is a sectional view, taken on the( line 4--4 of Figure 1, looking in the direction of the arrows. 4

Figure-5 is a modified form of a Hoor 3o plug embodyingmy invention when mserted in a Hoor, and

Figure 6 shows thesame asvadapted tobe used in a wall.

"Throughout the various views of the A drawings, similar reference characters designate similar parts. f p U My improved wall or doorY plug 1 is provided with a wooden filler 2 and a metal casing- 3 which 4may be any desired shape 40 according to the size and character of the filler. inthe embodiment of my invention shown in, Figures 1 to 4 inclusive, this plate.3 is bent back upon itself' at 4 and flanged at its ends 5 and provided with end ears 6 which take over the parallel surfaces. `'ll`he plates are also provided with a number of indentations 7 which givelthe mortar or vconcrete a chance to grip, and hold the ller in the lug.

5o When suci wall plugs are used in the conventional manner they arer covered by wood ounds or. finish, and as they are small 1t is often hard for a ca enter to locate them. 'llo make the work'ot location easier and more certain, l provide a finding wire 8 which extends about the wood 2 and is caught between the wood andthe adjacent metal sheet 3 so as to be firmly held. rlhis wire 8 shouldv extend from the center of the filler 2. f

If desired, the lug y`may be made with e metal sheet 3, as s own in Figures 5 and 6, with walls which are angular and bent inwardly vand then the filler 2 is made to correspond. In this embodiment the filler is gripped very yfirmly, as it is held in what might' be termed a dovetailed jointf This is a good construction for floors where strips of wood 9 may be held in place by a nail 10 which asses into the iller 2.

`When the structure shown in Figures 1 to 4 inclusive is used, the wall plug 1 is set in" mortarl 11 between bricks or other masonry 12, as soon as the mortar is put in place and before the-brick or other masonryx is placed on the mortar.y yWhen a oor plug is used, asy shown in Figure 5,

this plug 1 is inserted while the concrete .i

V13 is soft. In the preferred form of Hoor' plug, l provide a cap 14 as shown in Fig# ure 5, which is made of Ithin sheetmetal.

and protectsthe wood `from splitting. l In this structure, av finding wire 8 may be employed in which Aevent the wire passes through a suitable perforationin the cap 14.

lWhilefll have shown andy described some embodiments of my invention, it is obvious that it is not restricted thereto, but that it is ybroad. enough toicover all structures that come within the scope'of the annexed claim.'

Having thus described what lclaini is: Y

A. wall or vfloor plug comprising/.a .filler of fibrous material, anda metalcasing surroundi-n the filler on all sides but` one, the casing gbeing provided with outwardly turned flanges at its open end and being further .provided with non-perforating deiny invention,

pressions, which engage with the iiller on sanear, vv. norma.
