INVENTOR Sept. 24, 1929; F. N. ROPP JOIST HANGER FOR CONCRETE BUILDINGS Filed April 30. 1927 Z'mnif Y I A TTORN Patented Sept. 24, 1929 UNITED STATES FRANKLIN N. ROPE, LOS ANGELES, CALIFORNIA JOIST' HANGER FOR CONCRETE BUILDINGS Application filed April 30,

/ 17 This invention relates to joist hangers for concrete buildings, and the principal object is to provide an improved type of device including a socket or holding member adapted to be embedded in and rigidly supported in the concrete of a wall, and a detachable hanger held therein for receiving and holding the joist.

An important object of my invention consists in the provision of a two part hanger including a fixed member and a hanger detachably connected therewith, and so arranged that the fixed member may be supported on the forms for a wall without interfering in any way with the forms, and so that the concrete may be poured around it and operate to embed the supporting members therein.

Other and more detailed objects of inven- 0 tion will appear as the description progresses.

In the accompanying drawings I have shown a preferred embodiment of my improvements, subject to modification within he scope of the appended claims without departing from the spirit thereof.

In said drawings:

Fig. 1 is a perspective view of an assembled joist hanger embodying my improvements, and shown supported on a concrete wall.

: Fig. 2 is a transverse section of the same.

Fig. 3 is a perspective view of the hanger support; and

Fig. 1 is a perspective of the hanger proper.

As hereinbefore stated, my improvements consist in the provision of a two part device including a hanger H and a supporting member S therefor. Said supporting member includes a socket formed of an integral piece of steel or wrought iron, as at 1, bent substantially in the form of a square and adapt ed to be closed at its rear side by means of a jacket J extending around the'two ends and rear side and terminating at its front in longitudinally disposed flanges 2, 2.

The rear portion 3 of jacket J serves as a closure for the opening in the member 1, and said jacket is held in the position in Fig. 3 by means of a hanger rod R which extends through openings in the member J and 1, said openings being formed in the end per- 1927. Serial No. 187,736.

tions 4, 4 of member J and the corresponding sides of the member 1.

Rod R is extended at 5 longitudinally through the upper portion of the member S, and is bent upwardly at 6, 6 on an angle and thence outwardly at 7 7, in opposite directions to provide an anchor for the member S in the wall V of the building. The rear portion 3 of the jacket J is provided with outwardly extended lugs 8, 8, which serve to supportthe portions 6, 6 of the rod R. v

Member S is adapted'to be supported on the forms as at F, between which the concrete wall VJ is poured, and the flanges 2, 2 of member J are held in abutting position with respect to the inner surfaces of the forms F and are adapted to be attached thereto by nails or screws extending through perforae tions 9, 9 in said flanges.

The hanger H 1s of U-shaped cross section after the fashion of stirrups, and is provided with an enlarged central portion 10 with I tapering, side portions 11, 11, extending upwardly therefrom, and thence rearwardly at 12, 12 from which upwardly turned end portions 13, 13 areextended. The rear edges 14: and 15, 15 of the portions 10 and 11, 11 respectively, are adapted to engage the inner side of the wall W, while the lower edges 16, 16 ofthe portions 12 are adapted to rest upon the bottom17 of the member S. The portions 12=and 13 of the member H are so formed that the hangers may be readily inserted in position in the member S and as readily removed therefrom.

As shown in Fig. 2 the member H is tilted and the end portions 13, 13 are forced under the rod R and over the bottom 17 of member S, -Whereupon the hanger may be swung downwardly until the inner edges thereof abut the wall W. The portions 12, 12 are provided with notches'lS, 18 on the upper edges thereof for engagement with the rod B, so that the hangers may be'firmly held in position on members S while inluse.

The members H serve to support joists as at A, which are held on the bottoms 10 and between the sides 11, 11 thereof as shown, and

said joists may be attached to thehangers agamst accidental removal by nails or screws through perforations as at 20, 20, etc. Thus it will be observed that the hangers H when positioned in the sockets S are firmly held therein with their inner edges 16 resting upon the bottoms 17 of the sockets, and their inner edges 15, 15 resting against the inner side of the wall WV.

The rod R serves as a fulcrum about which the member H is rocked when being positioned in and removed from the socket, and at the same time serves to hold the hangers against accidental removal from the sockets. Said hangers also constitute anchors which extend upwardly at an incline and serve to bond thesockets S in the concrete.

The angular disposition of the portions 6, 6, of the rod R is essential for providing a maximum resistance of the supporting member S to removal from the wall TV, due to the weight carried by the joist A. Both of the members H and J are so designed as to provide a simple safety factor and a substantial over-load on the joist A without endangering the breaking or straining ofeither of the members H or S.

The improvements herein described and shown greatly facilitate the positioning and supporting of the joist supporting devices such as are used in concrete buildings, for the reason that the members S may be quickly attached to the forms F without in any way efl'ecting the forms or requiring cutting thereof. The concrete of the walls is poured around themembers S and the hangers H are inserted therein after the forms have been removed and the concrete of the walls is set.

Other advantages of my improvements than those herein named will readily appear to those skilled in the art of concrete building construction.

WVhat I claim is: j

1. A joist hanger for concrete walls including a pair of members detachably held together, oneoi' said members adapted to be embedded in the concrete of a wall, and the other of said members being pivotally and detachably connected with and supported in said embedded member, and common means carried in the embedded member for anchor ing said member in the wall and for pivotally supporting said pivotally held member.

2. A device of the character described including a socket member, an anchor rod extending transversely therethrough and having its ends bent rearwardly and outwardly at points inwardly of a face of and adapted to be embedded in a concrete wall, and a U- shaped hanger detachably held in said socket member and having side portions adapted for engagement with said rod for operatively supporting the same in position for use.

3. A device of the character described comprising a rectangular socket member adapted to be positioned in a concrete wall and having one side open substantially flush with a sur-' face of said wall, means for anchoring said member in said wall, and a hanger detachably held in the socket member and provided with side portions extending into and detachably connected with the sides of the socket member, and a supporting portion externally of the socket member and overlying the surface of the wall.

4. A device of the character described comprising a metallic socket member provided with a recess, an anchor rod held in said socket member and extending through said recess, a hanger detachably connected with said socket member and provided with terminal portions pivotally engaging said anchor rod, and a central portion depending from the socket member and engaging the adjacent side of said wall, for the purpose described.

5. A device of the character described, comprising a sheet metal socket member bent to provide a rectangular recess, an anchor connected therewith, a U-shaped joist hanger having lateral extensions extensible into the recess of said socket and detachably con nected with said anchor, said hanger depending from the socket and adapted to rest against the face of the wall for supporting a joist therein.
