FROEHLICH, OF BIRMINGHAM," ALABAMA WALL ANCHOR Application filed March 23, 1928. Serial No. 264,181.

My invention relates to means for securing and supporting an outer masonry building wall, such as of brick or stone, to the frame work or inner structure of a building, and has for its object the provision of a device of the character designated which shall be simple of design, easy of manufacture and which shall be adjustable as to position.

A further object of my invention is to provide a wall anchor for brick or stone walls which shall be readily, adjustable to position in a selected course of brick or stone in the wall and which shall furnish both vertical and lateral support to the wall.

A still further object of my invention is to provide a wall anchor especially adapted to support and retain a brick or stone wall against a reinforced concrete structure and which shall embody a wall supporting and tying element adjustable to position between the courses in the masonry together with novel wedge means to hold it in position, whereby, once located in position in the wall, vertical strain thereon serves to tighten the wedging means.

As is well known in the building art,,especially in constructing large structures, it is necessary to interpose anchors at regular intervals in the wall to serve both as a vertical and a lateral support to the outer masonry.

This has usually been accomplished by arranging bolts with outwardly extending threaded ends in the forms before the reinforced concrete girders of the building are poured, so that the bolts are embedded in the concrete, and afterward securing angle bars to the bolts with flanges extending outwardly into the masonry wall. While this forms a sturdy means of support when properly located, it ofiers considerable difficulties and expense in the way of application. For eX- ample, the angle barsmust have holes provided therein to receive the bolts thereby requiring accurate spacing of the bolts, and in pouring the concrete girders the bolts often become displaced so that they do not come directly opposite the holes, whereupon the angles must again be drilled to match the bolts. Furthermore, the courses in the outer wall rarely come di rectly opposite the location ofan angle bar so that a flange of the angle bar can lie between the courses without thickening the mortar joint or otherwise spoilouter appearance of the ing the symmetrical building.

These and other difficulties are overcome by means of my invention and. I have provided a wall anchor which is capable of being shifted both laterally and vertically to its position in the masonry wall and which requires no drilling of holes or cutting of the angle supports. Briefly, my invention comprises an anchor proper which is partially embedded in the concrete girders of the building or is otherwise suitably secured thereto,

and which embodies angle supporting means adjustable Vertically with respect to the anchor. The angle bar is supported on the vertically adjustable means by an extremely simvention is illustrated in the accompanying drawings, forming a partof this application,

Referring now to the drawing, particularly to Figs. 1 to 5, for a better understanding of my invention, my improved wall anchor comprises a retaining member 10 which may be made of relatively light sheet steel, or other suitable metal, and provided with rearwardly extending anchoring means 11 and 12, formed by bending the upper and lower portions of the retaining member 10 rearwardly. The members 11 and 12 are provided with holes 13 and 14 so as to be better held in a concrete girder. In addition to the re'arwardly bent portions 11 and 12 there are also provided rearwardly extending tongues 16 and 17 which are dovetail in shape, as seen in Fig. 2, and which are formed by cutting out the retaining member 10 and bending back the portions cut out, as seen in Fig. 3.

The retaining member 10 is made with downwardly converging sides which are bent over to ' form slots 18 and 19. An angle bar supporting member 21 has one side 22 inclined to the longitudinal axis of the member 10 and fitting in the slot 18. The other side 23 of the angle bar supporting member 21 lies parallel with the longitudinal axis of the retaining member 10 when the parts are assembled as seen in Fig. 1'. A wedge member 24 lies within the slot 19 and bears against the side 23 of the angle bar supporting member 21. The angle bar supporting member is provided with a lower arm 26 and an upper arm 27 which serves to support an angle bar 28 forming an anchoring shelffor a masonry wall 29, as seen in Fig. 5. In supporting the angle bar 28, the lower edge thereof is placed on the lower arm 26 of the supporting member 21 and the upper arm 27 is bent downwardly over the uperside of the angle bar 28.

It will be seen, with this construction, that as the weight of thewall 29 bears downwardly on the angle bar 28 the load transmitted to the member 21 forces said member more tightly into engagement with the sides of the slot 18 and more tightly against the wedge 24 resting in the slot 19. While the device so far described provides all lateral support for the wall which is normally needed, I provide slotted holes 31 and 32 in the member 21 and provide bosses 33 and 34 on the retaining member 10 and'having interiorly threaded holes 36 and 37 arranged to come opposite one of the holes 31 or 32. i A screw 38 may be em ployed to hold the supporting member 21 in place, once its location has been established.

In use, the retaining members 10 are secured in a concrete girder 41 at suitable intervals, in a manner to be described later, as

the main portion of the building is being erected. As the outside masonry wall 29 is built up to the retaining members 10, the angle bar supporting members 26 are adjusted by means of the wedge 24, to the proper height for the angle bars to lie in the joints between the courses in the masonry. The wedge 24 is then driven into tighten the supporting member 21 and the screw 38 is then tightened down and the angle bar 28 is put in place with the upper arm 27 of the supporting member 21 bent downwardly over the side of the angle bar 28.

It will be seen that inasmuch as there are no holes to be drilled in the angle bars, or no bolts in the concrete girder, the angle bars may be shifted from side to side to match the openings in the building and may be adjusted vertically to come opposite the joints in the courses of the masonry. Furthermore, the angle bar 28is permitted a limited adj ustment outwardly from the building by varying the location of the bend in the upper arm 27 and by the mason sticking mortar or other suitable backing behind the angle bar.

The retaining members 10 are put in place in the concrete girders by tacking them to the sides of forms such as 46, shown in Fig. 4, before the girders are poured. At this time, in order to prevent the slots 18and l9 filling with the concrete and to leave space for the supporting member 21 to be inserted after the girder is poured and the form removed, a wooden insert 47 of suitable length and fitting in the slots 18 and 19 is inserted in the slots. By referring to Fig.3 it will be seen that this method of embedding the retaining members 19 in the concrete girder provides a side support of concrete for the walls of the slots 18 and 19 which provision permits the use of much lighter material in the retaining member 10 than would otherwise be possible.

Referring now to Fig. 6, I show a modified form of my invention wherein the main structure of the building with which it is employed embodies wooden girders or frame work 51. WVith this form of my invention, 1 provide a retaining member 52 adapted to lie flat against the wooden girder 51 and having a suitable number of holes 53 to receive anchoring members such as spikes 54 driven into the girder 51. The other parts of the device are the same as has been described previously and the description need not be repeated.

From the foregoing it will be apparent that I have devised an improved wall an chor, simple of construction, readily adjustable in position to accommodate an outer masonry wall of the building and one which forms a sturdy support for such a wall.

While I have shown my invention in but two forms, it will be obvious to those skilled in theart that it is not so limited, but is susceptible of various other changes and modifications, without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are specifically set forth in the ended claims.
