Batentjed Dec. 23, 1930 NT. oFF-ics .FRAINKLIN N. ROPP, OF HOLLYWOOD, CALIFORNIA I COMBINATION JOIST HANGER AND TIE Application filed December 17, 1928. Serial No. 326,560.

' This invention relates to combination joist V hangers and ties, and the principal object is to provide a simple, economical and eflicient device embracing a hanger formed of an in- 5 .tegral piece of sheet metal and adapted to be supported on and anchored in a concrete wall for carrying the end of a joist, together with means attachable to the joist and connected with the hanger in such a manner that movement of the joist relative to the wall in any direction will be prevented.

With the above and other objectsin View, I haveshowna preferred form of device in the accompanying drawings, in which Fi 1 is a fragmentary'sectional elevation of a wall and a floor joist anchored thereon by means of my improvements.

Fig. 2 is a sectional plan ofthe same.

Fig. 3 is a perspective view of a tie bar adapted to have inter-locking engagement with the joist hanger.

Fig. 4 is a perspective view of a special and improved form of hanger forming part of my improvements.

Various and sundry means have heretofore been provided for supporting the floor joists at their ends on concrete and brickwalls, but the usual means provides only for supporting the joists and do not prevent the movement of the joists vertically and longitudinally rel ative t0 the wall.

I have shown and will now describe means, by particular reference to Figs. 3 and lof the drawing, whereby the joists may be so supported that they will be bonded or tied to the walls and will prevent movement relative thereto.

My improvements embody primarily a special form of hanger H, shown in Fig. 4, and a special form of tie bar B, shown in Fig. 3. The hanger is formed of an integral piece of sheetmetal, preferably wrought iron, is ofU- shaped cross section of a width corresponding to the thickness of the joist to be carriedthere- 4 in, and is of such a form that portions thereof may be imbedded in the wall for anchoring the hangers and joists permanently thereto.

The hangers H have parallel sides 72, and k1 connected at their lower extremities by means of a web, 7L2 with continuing inclined and rearwardly disposed upper portions b3, b3 which are bent inwardly at right angles at 7L4, 7L4 at their extremities. The web [L2 and triangular portions kii, 72,5 of the sides extend in wardly into the wall WV, as do also the portions b3 and he. The portions 7L5 and the web 7&2 serve to support the hangers'in the wall in the plane of the web, while inwardly bent portions k6 from the sides h and 72.1 are adapted to abut the face of the wall, as shown in Fig. 1. The portions 714, he at the inner extremities of the sides serve as anchors to receive the downward thrust of the joist J in connection with the portions 7L5. One or both of thesides h and k1 maybe provided with outwardly bent lugs 72.? and k8, as shown in Fig. 4;, whichare adapted to receive therebetween the downwardly bent ends 6 of the tie bar B. i

The form and position of the lugs 7L7 and 72.8 is such that the outer curved portionbQ. of the bar B will engage the lug h7,while the inner curved portion 721 will engage the lug ]L8, as shown in Fig. 1. The bar B, when de tachedfrom the joist J may be rotated downwardly, as seen in Fig. 1, for disengaging the edges 62 and 791 from the lugs h? and 7&8. Thebar B is attached to the hanger H by a reverse movement and may then be pernia nently attached to the joist J by means of a plurality of bolts, nails or lag screws, as at B, B, inserted through aperturesb, Z).

It will be observed that the aortion b of the tie'bar is bent outwardly, as shown in Fig. 2, to clear the side 7L1 of the hanger. In operation the hangers H are initially supported by suitable means on the form for the wall \V and the concrete is pouredaround the anchoring portions he and 7&5 of the hangers so that when the wall is set and the forms are removed the position of the ban gers will be substantially the same as shown inFig.1.

In such position the hangers will be firm ly imbedded and anchored in the concrete of 9 the wall and will be supported thereonrigidlyv enough to firmly hold'the joists J against displacement. The bars B are then swung into interlocking engagement with the hang-' ers by inserting the portions 6' thereof between the pairs of lugs 72 7 and 728 on the hangers. Thereafter the bars B may be attached to the joists by means of the bolts B or otherwise. v The joists J being'rigidly connected with the hangers H and said hangers being rigidly anchored to the wall W,the joists will be immovably fixed in their positions relative to thewall and a firm rigid structure will be provided. Such means of tying the joists to the anchored hangers in the walls renders a building more proof against damage by 1 reasonof earthquakes and the action "otthe" elements than would otherwise be possible.

What I claim is: 1.-.A joist hanger comprising a tJ-shaped member adapted to rest against the face of a wall. and provided withlhorizontal and vertical anchor portions at the base thereof adapted to be imbedded in a wall, and projections from the sides extending upwardly and rearward'ly into the wall and bent at angles therefrom for providing additional anchor portions above said base.

A joist hanger comprising a U-shaped member provided with base portion adapted to be imbedded in awa'll, lugs bent at right angles to the sides of the hanger tor engage ment with the face of a wall, and anchor por: tions extended upwardly and rearwardly from said sides and bent at their'innerends in the direction or each other for providing gnchors at points substantially above said ugs.

3. joist hanger formed of an integral sheet of metal having a stirrupior receiving 7 a joist with side portions extending upwardly and thence inwardly at an angle and provided with inwardly turned anchor portions at their extremities, portions bent inwardly from the sides for engaging the face of a 7 wall, and an extension on the rear side of said stirrup adapted to be imbedded in a wall, for the purpose described.

'4. A device of the character described comprising inlcombination with a wall and a joist adapted] to be supported thereon, a U shaped hanger for said joist imbedded in and anchoredto said wall, and bars attached to opposite sides-of and connecting saidjoist with said hanger for tying the joist tothe hanger against movement relative to the wall, said bars having end portions in interlocking engagement with the exposed sides of said hanger. 4

5. A device or the character described comprisin'ga hanger of U-shaped cross section having a base with a portion thereof adapted to be imb'edded ina wall, portions formed thereon for engagement with the face of the wall, anchors extending into said wall from the sides or said hanger, a joist carried in for the purpose described.

6. A device of the character described com- I prising a unitary hanger having portions extending into and imbedded in a wall, and astirrupexternally of said wall, a joist carried in saidstirrup, a'tie-bar attached to said joist,

and means for irreniovably connectingsaid tie bar with an exposed side of said stirrup when the tie bar is attached to said joist.

a 7. A deviceof the character described comprising a hanger having afstirrupexternal lyof and adapted to engage the face of a wall, supporting portions extending from thelbase of the stirrup into the wall, anchor portions vextending from the top of thestirrup into and adapted tobe inibedded in the wall, a joist carried in said-stirrup, and tie bars attached to the sides ofsaid joist and having "inter-locking engagement with the,

exposed sides of said stirrup,'for the purpose described. L 1

8. A device of the character described includinga U shaped hanger having anchor portions adapted to, be imbedded in a wall, F portions formed on the sides thereof form-e ing seats, a joist supported. in said hanger, and tie bars fixed to the sides of said joist and having end portions bent-at angles from the bodies of the bars. and confined in said seats for tying the joists to the hanger.
