Our invention relates to anchorage means to be placed in concrete.

The object of our invention is to provide an anchor housing that will bond in the concrete and the face thereof setting flush with the face of the concrete, andhaving an opening in the exposed portion to insert the head of a rod or other anchoring device so that masonry or other' kinds of finish may be tied 1c firmly to the concrete.

A further object of our invention is to provide an anchorage means that the anchor can be removed without mutilation of the housing.

A still further object of our invention is to provide an anchor housing that may be placed in brick, stone or other masonry walls by cutting away to insert the housing and then placing the housing therein, and flushing around it with cement it will function in like manner as in a concrete wall.

A still further object of our invention is to provide an anchor housing functioning as spacing and supportingmeans for reenforcing rods for concrete slabs, and simultaneously function as a support for anchor rods when ceilings are suspended from the floor slab.

A still further object of our invention is to make the housing of one piece of metal by l bending and cutting as hereinafter described.

Referring to the drawings:

Fig. l is the bottom view of the housing.

Fig. 2 is an end view, parts broken away for convenience of illustration.

Fig. 3 is a side view, parts removed showing the manner by which the anchor rod is placed.

Fig. 4t is a top view of the housing. 4U Fig. 5 is a cross sectional view showing the housing imbedded in concrete and having a ceiling suspended therefrom.

Figures 2, 3 and 5 show a re-enforcing rod placed on the housing.

Fig. 6 is an illustration showing brick anchored to a concrete wall by our anchoring means.

Fig. 7 shows the anchoring means in a conf crete slab supporting marble ceiling.

50. Fig, .8 is a reduced diagrammatical drawing of thev shape of the metal before bending to form the housing.

A more complete tion is as follows:

'We take a piece of sheet metal being of 55 proper gauge to resist the load imposed thereon and cut it similar to that shown in Fig. 8. It is then bent on the dotted lines shown thereon as follows: The laterally extending members A are bent on the dotted lines B forming an inclosure for the ends as at B in Fig. 2, and the remaining portion of the sheet on the lines C, D, E, F, G, H, and I, thesaid'letters will apply to the corresponding breaks as shown in Figures 2, 3,and 5. rlhe dotted lines J in Fig. 8 are the lines on which the stop members K are broke, and eX- tending inward as shown in Figures 2, 3 and 5. vThe wings L are cut from the flanges M after the housing is formed, and the cuts are v positioned as shown at M in F ig. 8. Centrally positioned in the bottom of the housing is a slot N and an aperture O, said openings being separated as shown .in Fig..8, and the metal therebetween is cut on lines P for the purpose of turning the ends formed thereby as heretofore described functioning as stops so that the anchoring rod head may be entered in the aperture as shown by dotted lines Q, and positioned as shown at R in Fig. 3. The anchor then is easily held in place and the head thereof can not pass through the slot which is designated for the bearing.

On the bottom of the housing and near each corner thereof is positioned .spurs SV which are cut from the folds of the flanges, the said spurs function as fastening means when the housing is placed on form boards T as shown in Fig. 2, and also for accurately registering with the joints of masonry when the form boards are vertically positioned. i It being understood that the spurs may lbe driven into the board until the bottom engages tightly thereon in which case the housing will be flush with the face of the concrete as shown in Fig. 5, and before plastering or other finishing is applied the said spurs may be bent back into the flanges from whence they were cut.
