VThis invention relates'tocertain new and useful improvements in adjustable shelfangle supports for building construction, and more particularly to a supporting member of this type which is capable of both horizontal and vertical adjustments between the shelfangle and theanchoragefrom whichfit is supported.l i. j

ln most modern building construction, the floors, interiorbeams and other load-supportingportions are carried by ai'structural frame of concrete or steel coveredwithconcrete, and the exterior walls are merely a sheathing of brick, stone, terracotta or other suitable material. In most instances, the outer walls are hung on or'supported bythe concretevframef work. `For the'purpose of vsupport-ing these outer walls over the window and `door openings, metallicsheli angles were bolted tothe concrete framework, and the lower rowof brick or similar material supported on this shelf angle. Y' ln multiple-story building construction, it is, usual `to support these outer walls at practically every floor level by means of similar shelf angles extending continuous'- ly around the building at each floor, so that any one level or story of brick work can be removed independently without disturbing the brick work above orv below that particular level.

In the first practical form of supporting means used, anchorage bolts were-cast into the concrete frame-work, these bolts having threaded outerendiportions which were insorted through holes in the rear vertical flange of the shelf angle. and provided with nuts for holding theV angle rigidly in place. This form of supporting means did not provide any means of adjustment', either vertical or horizontal'and since it is practically impossible to predetermine the exact inal position of the anchorage bolts, it was usually necessary to drill or burn special holes in the shelf angle to receive the bolts, after the bolts were in place. This isla very slow 'and expensive procedure. Metal inserts. have'heretofore been developed which were anchored' in the concrete structure and permitted avertical adjustment ofthe bolts used for. supporting the shelf angle. Even this construction the attaching bolt,and it isdifflcult'to prej determine the proper positioning-'of` the boltv holes inthe angle member. l Y

Tl'ef principal Vobject of the'invention v1s 10 with the Vfront wall 1 and flanges 4. Shorter anchoring wings may also'project from the endwalls42.VV It will be understood that these anchoring members mighttalre a variety of v different forms, their principal function being to provide sufficient anchorage" surface within the concrete frame in which the insert iis embedded.l The open rear side of the box- `like structure is lcovered by a second sheet metal plate 8 which is spot-welded, as at 8', to the side flanges 4. f In the. front face 1 of the insert is formed a T-shaped slot or opening, lcomprising a vertical slot 9 of a width suflicient to receive the stem 10 of the bolt, and with an upper opening 11 largeenough to f permit the insertion of the head 12 of the bolt (or of the nut 13 if the bolt and nut should bey reversed from the positions shown by yway of example in the drawing). One `or more holesr14v extend througheach side ,flange 4 and rear cover plate8 to receive the :nails used when therinsert is installed,'.as hereinafter described. It will be apparent that thesek improved inserts are very simple and economically constructed of two pieces of sheet steel by simpleV stamping operations,and when welded together, as at`8, a rigid and permanent assembly is provided. The firstrstep in installingthese metalinser-tsr is to mount them temporarily on the inner surface of the outer wall of the wooden fori-n i-n whichithe concrete is to be poured, as` indicated at 15 in Fig. 4. HRather long nails '16 are inserted through the holes'14, .hereinabove referredto, Vand the insert :is inailed against the inner surf-ace ofl the ',wooden form 15, as clearly shown in Fig. v4. It will be noted that the wooden wall ofthe formV closes the T-shaped slot in the insert .thatthe concrete cannot enter the box-like Structure. After-the concrete has been poured jand: lhas set, aspindicated at 17 in Figs. 1, 2

:and 3, the wooden forms are tornaway, leaving the metallic inserts firmly/embedded .with-,inthe concrete structure with the front Ywall 1 of the insert substantially Hush with the-outer face of the concrete beam. The projecting ends of the nails 16 can be-cut away., i Y j, In. previous constructions the shelf-angle 18, consisting of the horizontally extending flange Vllf'and-vfveI-'tieally extending flange 2O has been supported byextending the stems YlQnoffthe supporting bolts directly through suitableholes formed infthe Vvertical, iange 20,'whereby the shelf angle is bolted directly angle and support the same.

against the concrete beam 17 or against the inserts in case inserts are used. According to the present invention, a suitable hanger is interposed between the supporting bolt and the shelf-angle, and no holes are necessary in the angle member. In the form here shown, this hanger comprises a rear member 21 and afront member 22,` each formed of suitable strap metal, their upper end portions being superposed on'one another and 75 provided. with mating openings 23 for receiving the stemv10 of the anchoring bolt. The longerfrear -ha-ngermmember 21 has an outwardly extending horizontal flange portion '24 at its Vlower'end adapted to project 80 Fbeneath thehorizontal'iiange 19 of the shelfy The shorter front hanger member 22 is `bent outwardly vand downwardly `at'25 and 'provided with a vertically extending endportion 26 adaptedffk to overlap the upper portion of the vertical fiange 20 of the shelf-angle and prevent same from tilting outwardly. VThe assembly is locked lfirmly in `position by 'placing the nut 13 and washer 27 on the projecting end por- 190 tion of the stem 10 of the `bolt and screwing the nut down tightly. j j y In practical use, theinetal yinserts will first be anchored within the concrete structure in the manner describedrin detail hereinabove. "95p At some convenient time after theY concrete has setandthe forms have been removed, the bolt 10 maybe inserted in place within the insert f and the members y21 and 22 of the hanger and the nut 13 and washer 27 loosely 100 assembledon the projecting end of the bolt.V At any time thereafter Vthe shelf-angle 18 may be mounted in position by merely swingingaside the front angle members 22, resting the shelf-angleon the rear hanger mem- T bers l21 and then swinging the fr0-nt members 22 down into position, as shownzin Figs. land y2. V.It will be apparent that since there'are no holes or other openings to be engaged' in the shelf-angle, the exact horizontal positioning i'- of the insertsand hangers is immaterial, since any portion; lengthwise, lof the shelf-angle ymay be engaged by the hanger. VNormally the heads 12 of the bolts will restagainst theflower wall of the box-like structure of l1-i5 the insert, but Aincase some one or lmore of these inserts has not-'been` accuratelyv aligned .horizontallywith the other inserts, the corresponding'hangermay be properly positioned'by pushing up thehangerl members until 'F120 the supportingl shelfzportion 24 is properly beneath the horizontalfl-ange 19 of the shelf angle and then screwingthe nut 13 tightly j into. position. Suc-ha-.positioningV of the parts is ind-icated'inf 2;. 'Inany case,fthe '.125 assemblyzwill be heldl tightly in place` against either vertical or horizontal movements after the nut 13g-has been screwedidown to. draw the head of thefboltfirmly against the inner sirde *1 ofthe front wall 1 oftheinsert.

nemers Vertical adjustments might be provided for by forming vertically elongated openings 23 in the hanger members, in which case anchorage bolts of the type heretofore known might be embedded directly in the concrete structure and the special form of inserts omitted entirely.

While only a single shelf-angle has been shown as supported from the concrete frame 17, it will be apparent that two or more superposed rows of such shelving could be used if desired, the same forms of supports being used for each row of shelving.

It will be seen that this improved supporting device eliminates the necessity of all holes, slots or machining of any type inf the shelf-angle, which is merely clamped in position and'requires no special attention or v adjustment before it is mounted or while it is being mounted on the building framework. The supporting device is formedv of a few simple parts which are easily and economically constructed, and are easily assembled, and which have ample strength for supporting the load carried by the shelf-angles.
