In the construction of concrete buildings it becomes frequently desirable to attach structures and devices to the building afterthe concrete skeleton, framework or wall structure of 15 the building has been erected. For this purpose inserts have been used which are set into the concrete at the time the concrete is poured and by means of which suitable fastening devices may be attached to the said inserts for the purpose of supporting the structure to be applied to the building. In the application of wall y facings such as face brick and in the application of lintels, floors, brackets and other structures to the concrete walls or columns, it becomes necessary to adjust the position of the fastening means vertically to accommodate variations in construction and the irregularities procured in the erection of concrete buildings by the ordinary methods. In the past it has been attempted to procure such adjustment by the use of notched supports, whereby a step by step adjustment could be procured. Such devices have been found impracticable due toy the fact that close enough adjustment could not always be procured. Considerable difficulty has also been encountered in the past, in preventing the concrete from entering the space in the insert in which the fastening means is disposed. The present invention provides an insert in which any degree of adjustment can be procured and in which the adjustment can be easily and quickly made and further provides a device which willv keep the concrete out of the interior of the insert.

As brought out, the invention may be used in a number of dilferent ways and for the purpose of illustration the invention has been shown as used for vsupporting face brick along a concrete Wall. In Fig. 1 a part of a concrete wall Ill has been shown and in Fig. 2 the form boards have been illustrated which are disposed adjacent the wall lll. Applied to the wall I0 is a facing 3l of a brick which consists of individual `separated by mortar joints 23, said facing being supported on angles 51.

My invention proper comprises an insert indicated in its entirety by the reference numeral II. This insert is provided with a body portion` 33 which is box-like in form, being formed with a cavity 32 upon the interior thereof. The body 33 is' constructed in two parts 34 and 35 which are stamped from sheet metal. Body 33 is provided with a front wall 42, a rear wall I1, side walls 36 and 31 and end walls 38 and 39. The part 35 embraces the rear wall I1 and the two end walls 38 and 39. These parts are formed from a strip of metal which is bent in the manner shown. The part 34 embraces the front wall 42 and the two side walls 36 and 31. These parts are bent out from a single sheet of material in the manner shown and are adapted to receive between them the part 35. The ends of the walls 38 and 39 abut against the inner surface of the front wall 42 and the edges of the end walls 38 and 39 and the rear wall I1 ts up against the inner surfaces of the side walls 36 and 31. The two parts 34 and 35 are held attached to one another by means of lugs I8 which are formed on the inner edges of the side walls 36 and 31 and which are bent about the rear wall I1. In addition protrusions 4I are punched into the front wall 42 which engage the end walls 38 and 39 and hold the part 35 from longitudinal movement with respect to the part 34. By means of this construction the two parts are securely held together and completely deprived of movement with respect to one another.

The front wall 42 is constructed with an opening I4 ,in the nature of an elongated slot which terminates short of the ends 38 and 39. Within the cavity 32 in the body 33 is disposed a nutV I9 which isthreaded at 43 to receive a threaded shank or member 2|. This member is in the nature of a bolt and extends through the slot I4, being adapted to be slid vertically along said slot together with the nut I9. The side walls 36 and 31 of the body 33 are arranged in diverging relation as shown in Fig. 2. The nut I9 has beveled surfaces 44 and 45 which are adapted to t against the inner surfaces of the side walls 35 and 31. When the nut I9 is urged toward the front wall 42, the surfaces 44 and 45 wedge against the side walls 36 and 31 and frictionally hold the nut in position. Nut I9 remains permanently within the cavity 32.

The rear wall I1 of the body member 33 is constructed inclined and is arranged in downwardly converging relation with. respect to the front wall 42. The threaded member 2I is adapted to engage the inner surface 45 of said rear wall and when the same comes into engagement therewith, the inclination of said wall and surface limits the further downward movement of the saidthreaded member and nut I9. To facilitate the turning of the threaded member 2l, the same is constructed at its end with a square head 41 whose diagonal dimensions do not exceed the diameter of the threads of said member. By means of this construction a nut i have nail holes I3 therein. Nails 48 are inserted through these holes and driven into the form boards 30 which hold the device securely attached to the form work while the concrete is being poured.

In order to securely anchor the insert in the concrete, flanges 49 are turned outwardly from the Walls 36 and 31. In addition wings 5I and 52 are formed on the said side walls 36 and 31 which lie in continuation thereof and project outwardly beyond said side walls and beyond the rear wall I1 and the end wall 38 of body 33. These wings have holes I6 in the same through which a reinforcing rod 53 may be inserted which projects outwardly beyond the two wings and becomes imbedded in the concrete. In addition, flanges 54 are formed at the edges of these wings which serve the same purpose as the flanges 49.

To prevent concrete and foreign materials from entering the cavity 32, a cap 24 is employed which is adapted to cover the slot I4. This cap consists of a part 55 conforming in configuration to the shape of the slit I4 and adapted to t into the same. This part is surrounded by a ange 56 which limits the movement of the cap and provides a means whereby the cap may be readily removed after the insert has been set in the concrete. This cap is only used temporarily when the concrete is poured and is dis carded when the insert is placed in use.

The manner of using the invention is as follows: Assuming that the inserts are to be used for supporting a brick facing,k as shown in the drawing, inserts with caps v24 applied are attached to the form board at the required localities by driving the nails 48 through the nail holes I3 and into the forms. This holds the caps in place. Thereafter reinforcing rods 53 are set in the openings I6 and when everything is in place the concrete is poured. The arrangement of the parts after the concrete has been poured has been shown in Fig. 4. It will be noted that the cavity 32 is completely sealed so as to protect the nut I9 disposed within the same. After the concrete has suiciently set, the forms are removed and in removing the forms, nails 48 are pulled out of the form boards which nails project outwardly beyond the ears I2. These nails are next cut oif flush with the surface of said ears. Caps 24 are next removed by forcing a screw driver or chisel under the flanges 56. All of the threaded members 2l are then inserted through the slots I4 and screwed into the nuts I9. For supporting the brick, the angles 51 previously referred to are used. These angles are drilled with holes to slip over the appropriate threaded members. The lowermost of rthese angles is i'lrst applied. The members 2| supporting the same are then readjusted for elevation by unscrewing said members through the heads 41 thereof and raised and lowered until the proper elevation is procured. When proper adjustment is secured. said threaded members are screwed in until the ends thereof engage the surfaces 46 of the rear walls I1 of the inserts to which they are applied. This holds the said threaded members in place. vThe nuts 22 are next screwed upon the threaded members clamping the vertical drilled flanges of thelowermost angle 51 securely against the surface of; the concrete and against the front walls 42v of the inserts to which it is attached. The laying of the brick then commences'and the rstrow is laid upon the lowermost angle 51. Where the nuts 22 and the heads 41 of the threaded Vmember 2l are disposed, the bricks are notched and such portion of the same lled with the mortar. The laying of successive rows of bricks then continues. The angles 51 are arranged one above the other at suitably spaced distances to give the desired support to the brick work. When a superimposed angle is reached the elevation of the same may be adjusted by means of the threaded members 2l and the nuts 22, until the lower flange of the angle rests upon the last laid row of bricks. Threaded members 2| and nuts 22 are then tightened and the laying of bricks proceeds. It will thus be seen that the angles may be adjusted so that the same are disposed in the joints between the bricks to eliminate chipping oi the bricks as is ordinarily the case. Where the inserts are used for supporting lintels and other building structures, the same procedure is adopted. The supporting member carried by the fastening means may be adjusted and leveled prior to the installation of the lintels thereon and after the fastening means have been properly adjusted the lintels are installed.

My invention is highly advantageous in that an extremely simple and practical device is provided which may be quickly and easily installed. With my invention any degree of adjustment can be procured so that the device will adapt itself to uses for which other types of inserts are unsuitable. lVIy invention is constructed from metal stampings .and may be produced at a relatively low cost. By means of the cap used, concrete is prevented from entering the cavity within the device during the pouring of the concrete, so that the device when desired for use is free from foreign matter. By means of the reinforcing rod used the insert can be made to support an appreciable load. Due to the inclination of the rear wall, dropping of the load after the device is applied is completely prevented. The stresses set up in the device through the application of the load tend to urge the parts against the adjoining concrete placing the various structures in compression and thereby causing the parts to become rmly held in place. By means of the specific construction of the insert, the same is rmly imbedded in the concrete and will not readily become detached therefrom.

Changes'in the specic form of my invention, as herein disclosed, may be made within the scope of what is claimed without departing from the spirit of my invention.
