Fatented Jan. 19, 1932 PATENT FEQE WILLIAM M. GOLDSMITH AN D BENJAMIN HARIG, OF CINCINNATI, OHIO, ASSIGNORS TO THE GOLDSMITH METAL LATE COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO STRUCTURAL INSERT Application filed March 12, 1929. Serial No. 346,475.

This invention relates to inserts used for attaching face angles to concrete lintels or the like and is adapted for various uses, a few of which will be related herein.

Inserts of the general type with which the invention is concerned are shown in such patents as Downing, et al. 909,7 69 and Bright 1,035,525.

Inserts of thecharacter under consideration are used for supporting pipes from ceilings and walls, for attaching metal angles to concrete structures whereby to provide support ledges upon which masonry and brick work may be built up, for supporting shaft hangers, etc.

An object of the invention is to provide a simple and efiective device that may be easily and economically fabricated, but which will have all of the advantages of other more 29 complicated and expensive devices, besides having certain other advantages and features, some of which will be enumerated hereafter.

Another object of the invention is to provide a device of the character indicated wherein various parts thereof may be so adjusted as to accommodate the insert to various situations that may develop and whereby accurate positioning of angles, pipe hang- 39 ers and the like, may be attained.

Another object is to produce a device that will provide a substantial and secure mounting for angles and similar supporting devices that may be attached to or held by an insert.

These and other advantages are attained by the means described herein and disclosed in the accompanying drawings in which:

Fig. 7' shows an end elevation of a modified form of the device.

Fig. 8 shows a fragmental inverted plan view of the device shown in Fig. 7.

Fig. 9 is a sectional view on line 99 of Fig. 8.

The preferred form of receptacle is disclosed in Figs. 5 and 6, wherefore that con struction will now be explained.

The receptacle shown in Figs. 5 and 6 consists of a body, preferably of heavy gage material with a face 10.

The face is provided with an elongated opening 11 that is generally rectangular in form. At the ends of the face are provided upwardly extending arms or walls 12 and 13. Along the side or lateral edges of the face are provided upwardly extending flanges 11 and 15. The flanges are considerably shorter than the end walls 12 and 13, reinforce the face and cooperate with the end walls 12 and 13 for receiving and supporting a substantially U-shaped cap member 16. The cap member is preferably of sheet metal of a lighter gage than the body of the device and is retained in inverted position between the ends 12 and 13 and may have its arms 17 and 18 disposed exteriorly of the flanges 14 and 15. The arms 17 and 18 of the cap member 16 are flanged at their free ends, the indicated flanges 19 and 20 provided on said cap extending outwardly and extending in substantial parallelism with the face 10 of the body member. Preferably the under surfaces of the flanges 19 and 20 and of the face 10 lie in a common plane. The cap and the body member are intended to fit together in such reasonably close or snug relationship that the void or chamber provided between the cap, the face of the body and the walls of the body, will be reasonably water tight to avoid seepage ofplastics such as cement and concrete into that chamber. The flanges on the cap may be provided with perforationssuch as are indicated at 21, and through which perforations suitable fastening means such as nails, may be inserted for securing the device to a temporary form or mold within which the device is intended to be positioned and into which mold or form plastic is introduced.

The upper extremities of the arms or end walls 12 and 13 may be so formed that the ends of those arms will bond or look in a plastic mass. Accordingly, the free ends of the walls 12 and 13 are bent so that portions thereof converge over the cap 16 and other portions thereof diverge. If desired, suitable perforations indicated at 22 may be provided in either the converging or diverging portions of the arms of the members 12 and 13 for sup iilementing the locking function attained by the indicated distortion or configuration of the free ends of said members.

By providing the opening 11 in the face 10 of the body member, there is provided a ledge-like structure extending about said opening 11. Upon that ledge-like surface there may rest a suitable carrier means 23. The carrier means may be of various forms, for example it may be in the nature of a piece of channel iron as indicated in Figs. 5 and 6, or it may be in the nature of an annular washer such as is shown in dotted outline in Fig. 6 and in Figs. 1 and 2. The carrier means contacts the ledge and co-operates with a suitable bolt 24. The arrangement of the carrier means and the bolt, together with the supporting ledge on the body 10, is such that the bolt may be adjusted to a position longitudinally and transversely of the opening 11 by shifting the carrier means 23 relative to the body member 10. In the form shown in Figs. 5 and 6 it would be necessary to adjust the bolt 24 longitudinally of the elongated slot 25 provided in channel 23 for attaining adjustment of the bolt transversely of the opening 11, whereas if the channel 23 is superceded by a Washer such as shown in Figs. 1 and 2, the washer would be rotated upon the ledge about the opening 11 for attaining transverse adjustment of the bolt relative to the opening 11.

The bolt 24 may have its head 26 received between the arms 27 and 28 of the channel iron 23 or a suitable nut may be introduced between arms 27 and 28 and may be retained against separation from said channel iron 23, in any suitable manner so that subsequently the threaded shank of a bolt may be introduced into the nut, the nut being slidable longitudinally of the channel iron 23. When using a was er such as shown in Figs. 1 and 2 in connection with a receptacle member such as is shown in Figs. 5 and 6, the washer may he provided with a plurality of bolt receiving openings of various diameters. The indicated openings in the washer may have smooth walls or they may be tapped or threaded so that the washer will cooperate with the head of a bolt or with the threaded shank of a bolt.

If desired, the distorted upper portions of the ends or arms 12 and 13 may be dispensed with and in lieu thereof there may be pro vided suitable rods such as are shown at 30 and 31 in Fig. 7, which would be so associated with the receptacle member that the receptacle member may be locked into a plastic mass after such mass has set.

The structure shown in Figs. 7 to 9 inclusive comprises a receptacle having a face 32 substantially identical with face 10 shown in Figs. 5 and 6. The member 32, however, is provided with upwardly extending flanges along its lateral edges only, the ends thereof being provided with no flanges or ends corresponding to the ends 12 and 13 shown in Fig. 5. The cap member 33 corresponds with the cap member 16 shown in Fig. 5 and may be provided with perforated flanges 34 corresponding with the flanges 19 and 20 on the cap 16. The support rods such as 30 are intended to be inserted through suitable openings provided in the heavier gage metal used in providing the body of the device. It is to be understood that if flanges be provided upon the ends of the member 32 rather than along the lateral edges thereof, the rods 30 would extend at right angles to the positions at which they are shown in Figs. 7 to 9 inclusive. The rods 30 may be given any suitable configuration to effect a suitable bond or lock with the concrete mass formed about the device. In some instances the rods might be straight wires, provided the rods are spaced a suflicient distance from the face of the device to effect a sufficient lock with the concrete to support the weight of the fixtures or angles that are intended to be secured to the insert. An illustration of straight rods in lieu of deformed rods such as 30, is shown in Figs. 1 and 2.

The forms of devices shown in Figs. 1 and 2 are made in accordance with the general principles and explanations previously given and differ therefrom only in that the rods 40 perform the same function as do the ledges in the forms shown in Figs. 5 to 9 inclusive, as well as to serve as bonding members for retaining the device in fixed relation to and in a concrete mass. The rods 40 may be deformed or inclined as indicated at 41, in Fig. 4. The flanges 42 may be provided with suitable apertures such as 21 for attachment of the device to a. form or mold. The annular washer 43 may be provided with variable numbers of apertures 44, of variable diameters, and the walls of the apertures may either be smooth or threaded as previously explained.

When the receptacle is disposed in such position that the washer 43 extends in a. substantially vertical plane, the edge of the washer may contact with or rest upon one of the side walls of the receptacle or upon the lateral flanges extending from the face plate 10 of the receptacle.

When the washer is so positioned, the washer may be said to be supported by the side wall of the receptacle. It is to be understood however, that by supporting means for the washer Or disc, reference is made to the ledges or rods l0 that support, sustain or retain the washer in the hollow receptacle and which resist the strain. directed upon the bolt and washer or disc.

W hat is claimed is:

1. In an insert of the class described, the combination of a receptacle member comprising means for bonchng the receptacle in a plastic mass and ledge forming means, a carrier adjustable longitudinally of and arculately upon said ledge forming means, and an attachment device supported by the carrier and retained against bodily movement relative to said carrier.
