INSERT FOE CGNCBJETE "WALLS AND THE LIKE.

Application filed July 11, 1925.

h iy invention relates to metal anchoring devices which are designed to be applied to cement walls, particularly in the ceilings (of horizontal walls, or floors, and such as are commonly termed inserts in the cement building; art. lhese inserts, usually formed of cast iron, are placed in the ceiling when it is poured, and are used for the attachment of hangers for shafting, machinery, motors or other electrical apparatus or fixtures, pipes, radiators, trolley tracks, or anything which it is desired to suspend from the ceiling. They may also be used for bolting timbers to the ceiling in. the con struction of partitions, or for other purposes, or a spaced pair of them may be used in connection with U-bolts formed with heads at the ends of their parallel portions, for use in storing pipe, rods, or similar articles. Various forms of such devices are ltnown in the art, and it is the object of my invention to produce an improved insert, designed to be used in connection with a standard square-headed bolt as a conueco member, and of novel and original conruction, wiich shall be better adapted for the purposes for which it is designed to bk used than previous devices lanown to me, and which because of certain novel features ot construction, hereinafter described in detail, will be part-iculai'ly strong, simple and compact in construction, afford maximum holding strength in the concrete, and afford a convenient and secure anchorage for the devices supported thereby. l fith the fore going objects and advantages in view l have del'p gned the novel insert illustrated in tie accompanying drawing and hereinafter de scribed in detail, the essential elements oi' my invention being more particularly pointed out in the appended claims.

In the drawing, Fig. l is a side elevation of the insert, the concrete l about it being shown in section; Fig. 2 is a vertical section in a plane indicated by the broken line 22 of 1; Fig. 3 is a central vertical sec tion in a plane at right angles to the plane of Fig. 2; Fig. l is a horizontal section in a plane indicated by the brolren line l l of 3: Fig 5 is a bottom plan view oi the 1 A} i device; and Figs. 6 and 7 horizontal sec- Serial No. 42,895.

tions corr sponding to Fig. l but on a smaller scale, of different modified forms of my invention.

Like reference characters indicate like parts in all the figures of the drawing.

My novel insert may conveniently and economically be formed of cast metal, as cast iron, and consists of a single integral shell having; as its top portion a square top plate 1 which overhangs vertical side walls connected at the bottom to a square bottom flange 4: which projects laterally from the side walls. Gt the side walls of the insert two adjacent upper walls 55, standing at a right angle to each other, extend about half way down from the top plate toward the bottom flange, and diagonally across the insert two other adjacent upper walls, 6-6, standing at the same angle from each other, extend from the top plate to a plane a short distance above the bottom flange. Below the walls 5 5, and ofiset from them towards the center of the insert the casting is formed with lower walls 7-7 which in the present instance are somewhat rounded at their unction with each other; and below the walls 66, and similarly oti set towards the center, the casting is formed with two other lower walls 8-E, also rounded at their junction with each other. lhe outer portion of each upper side wall 5 and corresponding lower is connected with the outer porside wall tion of the upper side wall 6 and correspond ing lower side wall 8 which stand in planes at right angles to their own planes, by a ver tical side wall 9, the two opposite side walls 9 therefore being parallel with each other and being disposed diagonally with respect to the edges of the top plate 1 and the bot tom flange 4, as well as the other side walls. In the present instance, though not necessarily, the walls 9 are termed each with a transverse exterior rib 9 about midway between the top and bottom of the insert.

inasmuch as the lower side walls 7 and 8 are offset inwardly from the

upper side walls

5 and 6, respectively, the width of the side walls 9 is reduced below each offset, and opposite the wall 8 the space within the insert is approximately square in cross section and ofiset slightly towards the center of the insert from the square opening between the walls 66 and the-lugs 1010.

At the interior shoulder formed by the upper and lower side walls 5 and 7 on one side of the device, the metal ofthe casting is extended continuous with the shoulder, and continuous with a pair of triangular right angled lugs 101O on the .op-

posite side walls 99 which rise abovehthe purpose of accommodating the shaftiof the 7 Diagonallyacross the insert, and below the level of the, seat for the bolt head, the ofls et arrangement of the walls Sand 8 forms inside and outside shoulders, similar to those formed by the walls 5"and 7.

The flange 4 of the insert is the present instance formed with a shallow countersunk recess extending outside the line or the side walls 7, '8 and 9, to receive a closure plug which may be inserted and, if desired, plastered over, in case the insert is installed for future use, and, it is desired to close it up until the time for its use arrives.

It will be understood that my novel insert is intended to be moulded in place in concrete or cement flooring in the usual man her, and in practice it is customary toplace the inserts in the position on the face of the form and pour the plastic cement around them. To hold them in position during this operation the bottom flange 4 of the insert is formed with notches 12 to engage brads driven into the form. r

Y The overhanging .top or the insert, the exterior shoulders midway of the insert at the bottom of the walls 5, heribs S on the Walls 9, and the exterior shoulders near the 7 bottom or" the insert below the wallet, it may here be observed,rdistribiite the weight of the loadthrough the mass of cement most efie'ct-ively so that maximum load-carrying capacity is attained, These shoulders, moreover, provide convenient faces under which reinforcing rods for the concrete may be placed, ifdesired. V ,7 a I r The inserts being installed as above described, it. is, obvious that .the bolt being held in. vertical position with its, head up permost it; may be inserted through :the approximately square opening at. the bottom, raised andmoved. slightly-to the riulit; (as theparts areviewed. inFig. 3"), lirtedto clear the lugs 10-t10,- shifted to the left over said lugs and loweredintothe. socket beh nd the lugswhere it will be held securely and formed by the inner faces of the sides 55 vand the adjacent races of the lugs 10-10,

extended, and theo'ther square as formed by the.

sides

6, 6 and the other two faces of such lugs, extended. The bolt head is seated in its socket ona ledge which on two sides ofthe head is directly above the side walls 77 and whichoppo site onehall of each of the other twb sides is continuous with the lugs lO-' l0.- An exceedingly'sturd'y and secure construction is thereby attained.

If desired a nut as indicated in Fig; 2 and marked B', engaging the bolt and bearingthrough a washer (ordirectly) against the base of the insert may be employed to positively preventdisplacement of the bolt head from its seat, although in many cases this will be wholly unnecessary,

It will be understood that while the construction above described is believed by me to be the best form o tmy invention, it is susceptible of variation and modification, and in Fig. 6 I have illustrated a modified form of my invention, designed to be used connection with a bolt having a hexagonal head. In this casethe interior angle between the upper side walls 5 5 and 6* '6 are arranged at an angle of 120 instead of an angle of as in the case or the corresponding walls 55 and 66 of the preferred form of my invention, and the triangular lugs 1O-1O are smaller and further a'pa'rtfthan the lugs of such preferred form. The side walls 9"'9 in this form of my invention are relatively much longer than the sides 99 of the preferred forni.

In "Fig 7 I have illustrated a second modified form of my invention also adapted for use in connection with a bolt-having a hexagonal head, in which a side of the bolt head isarranged to lie against an upper intermediate side wall 15 connecting the upper side walls 5 5 and the walls (E -6 are similarly connected by an upper intermediate side wall 16. In both of these modifications, the other portions of the insert may be the same as in the preferredtion of proportions.
