This invention relates to building constructions and more particularly to an improved concrete building block adapted to be used about the marginalportions of a window opening.

: An object of this invention is to provide a concrete building block which includes metallic means anchored thereto and to which a metal window frame may be-secured so that the window structures in localities subjected to termites may eliminate as much wood as possible about the building.

Another object of this invention is to provide an improved building block for use about a window opening which-includes a soft metal strip which is anchored to one portion of the block and to which the metalwindow frame may be firmly secured. g

A further object of this invention is to provide [an improved window frame attaching means in .20 the form of a substantially triang-ularly shaped strip which is anchored to one side of a concrete building block, the strip having a length substantially equal to the height of the block so that when a series of these blocks are superposed 925 one upon another or placed in side by side relation, a metal frame will be provided to which the metal window frame may be firmly secured.

To the foregoing objectsand to others which may hereinafter appear, the invention consists 30 of the novel construction, combination and arrangement of parts as will be more specifically referred to and illustrated in the accompanying drawing, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed. In the drawing: Figure 1 is a perspective view of a building block constructed according to this invention, and Figure 2 is an enlarged fragmentary horizontal section through one portion of the block.

Referring to the drawing, the numeral [0 designates generally a concrete building block which is provided with an opening I3 through the center thereof. The block In is provided with a straight inner face H which at one end thereof has a vertically extending recess l2. The outer face I of the block I0 is substantially straight for the greater portion of its length and at one 50 end the outer face I4 is rounded off as at I 5. This rounded portion l5 terminates in a concave portion l6 which merges into a flat face I I disposed at an angle of substantially forty-five degrees to the face l4. One end l8 of the block 55 I0 is inset from the adjacent edge of the angled portion il' as at is, the purpose for which will be hereinafter described.

A soft metal strip is adapted to be anchored to the block lll'and comprises a strip which is triangular in transverse section as'shown in Figure 2. This strip 20 is adapted to be constructed out of lead or other soft metal and in which screws or nails may be threaded or driven. The strip 21'] is anchored to the block l0 by-an anchoring member which comprises a stem 2| which ($19 is embedded at one end in the triangular strip 28. The inner end of the stem 2i is provided with a V-shaped anchoring portion 22 which is embedded in the block l0. Preferably, the strip 28 is anchored to the block H] at the time the block' H1 is cast or is in plastic form.

The triangular strip 20 is adapted to be engaged by'an angle window frame member 23 which is adapted to be secured to the exposed faces of the strip 20 by fastening devices 2 l'ini20 the form of screws or the like. If desired, a sealing means 25 may be interposed between the angle frame member 23 and the strip 2|].

The outer face l4 and the arcuate portion ii of the block H] are adapted to have a coating 26 25 secured thereto, this coating being in the form of stucco or the like. A plaster 2! is adapted to be mounted on the end face l8 of the block 10, the plaster 21 having a thickness substantially equal tothe depth of the insert portion of the end face I I8 so that in finished form a smooth end face will be provided on the block I. A wooden strip 28 is adapted to be mounted in the recess 12 on the inner side of the block l0 and a channel member 29 is used to receive the slide members of a Venetian blind which are adapted to engage in the channel member 29. The channel member 29 is secured to the vertical strip 28 by fastening members 30.

A second wooden strip 3 l is secured to the, inner 40 face ll of the block l0 and to the strip 28 and plaster 32 is adapted to be mounted on the inner face ll of the block I0 and if desired may cover the inner face of the strip 3| and the inner edge of the strip 28 and also extend in the space between the inner edge of the channel 29 and the inner edge .of the strip 28 as shown in dotted lines members 2l--22 will be firmly anchored in the body of the block Ill and the inner face of the strip 20 will snugly engage the angled face portions ll of a block l0.

When these blocks are placed on opposite sides of the window opening in superposed relation, a pair of vertically disposed soft metal strips will be provided to which the window frame member 23 may be secured. These blocks It may be also mounted across the upper edge of the window opening and if desired, may also be mounted on the sill or lower portion of the window opening. Where this is done, a substantially continuous soft metal strip is provided entirely around the window opening to which the window frame may be secured.

What I claim is:

1. In building construction a non-metallic wall block having an outer side face formed with an inset forward portion and an outer end face formed with a portion inset with respect to the outer part of said forward portion, a soft metal strip positioned against said forward portion, and

1 means for anchoring the strip and block together.

2. In building construction a non-metallic wall block having an outer side face formed with an inset forward portion and an outer end face formed with a portion inset with respect to the outer part of saidforward portion, a soft metal strip positioned against said forward portion, and means for anchoring the strip and block together, said strip corresponding inwidth and length to the said inset forward portion and having an edge flush with a party of said end face.

3. In building construction, a hollow concrete wall blockhaving an outer end face provided with front and rear rabbets, said block having an outer side face formed with a non-inset rear portion and an inclined inset forward portion merging into said end face at one side of said ,front rabbet, a soft metal strip of triangular cross section disposed throughout said inclined portion and inset with respect to the said non-inset portion, and means for anchoring said strip to said block.

4. In building construction, a hollow concrete Wall block having an outer. side face formed of a non-inset rear portion and an inclined inset for- 'ward portion, a soft metal strip of triangular 5. In building construction, a hollow concrete 5 wall block having an outer side face formed of a non-inset rear portion and an inclined inset forward portion, a soft metal strip of triangular cross section disposed throughout said inclined portion and inset with respect to said non-inset portion, and Y-shaped means'having its V and a portion of its stem embedded in said block and the remaining portion of its stem embedded in said strip for anchoring the latter to the block.

6. In building construction, a hollow concrete wall block including an outer end face and an outer side face, said outer side face being formed of a substantially straight rear portion, an in-- wardly extending rounded intermediate rear portion, an inset concaved intermediate front portion and. an inclined inset forward portion dis posed at an angle to said concaved portion, said straight portion merging into said roundedportion, said rounded portion merging into said concaved portion, said concaved portion merging into said inclined portion, said inclined portion merging into one side of said'end face, a soft metal strip of triangular contour seated'throughout against said inclined-surfaces and flush with one side of said outerend face, and means. embedded in the block and strip for anchoring them together.
