. Boots and floors of some large buildings are commonly formed by laying what is known as roof deckingv on supporting beams and girders. In Fig, l, I have illustrated one form of roof construction commonly used and consisting of a series of interlocking panels I. having an inverted ll-shaped cross section with side flanges 2 and 3.
" I'he left side flanges are provided on their lower edge with outturned rims 4 and right flanges 3 are provided on their lower edge with return bend folds 5 and laterally extending rims 6. The panels are assembled on suitable structural supports in an interlocking relation with the left rims 4 supported on the right rim 5 of the preceding panel and interlocking in the U-shaped th dec ane l e the.
2 fold 5. Mybracket is designed tobe mounted on this type .of roof or floor decking.
My bracket consists of a strip of metal formed by stamping, bending .or otherwise to provide .a central base 1 with depending arms 8 and 9. on the ends thereof. The base is longitudinally slotted as at lfland is provided with side flanges ll which serve to stifien. the base.
The left arm ,8 extends approximately perpendicularly with respect to the base and is provided on its lower endwith an outturned flange l2 ten.- minating in a hook. 13. As illustrated, the flange l2, and hook l3 are arranged to fit around and grip the. return fold 5 and rim 6 of one panel of th .deokingwith the arm 8 extending verti, cally inside of the left arm 2 of the next ad.- Jacent decking panel. The right arm 9 of my bracket extends at a slight outward angle from perpendicular to. th end .Of the base 1 and is substantially shortertha he left arm 8 so that the lower end ofathe rig rm will fit within the decking panel andrestjii ,ntheztop surface. of the returnfold 5. Preferablythe armed-and Sare of such-a length that the top edges of the. flanges ll willhear against the under side of;
the panel l."
The bracket is-made of metal which is. sufficiently springable so that theri ht arm 9 will be displaced in pressing it into the deck panel.
tween the flanges H and defines a pair of tappecl' holes l5 for the reception or screws It. The screws areoneratiye to. secure various types or fixtures and-hangers to the bracket.
In s. 1 to. 3 I have illustrat d an lect cal outl t x. I secured to the b cket by m ans of the screws l6. Electri al condu s an be attaehed to and suppor ed by. the o tl t box in the normal manner. 11 E 12.v "I h ve illus rat d a -shapcd han er L8 s ured o he br c et by the screws 16 and seryine sup o a n h o pipe or conduit v,O her types of fix u s and han ers may 1b h o: my r ck as d sired as will rea appreciated.
My hanger is light;and inexpensive to manufacture and can be quickly snapped in place at any desired position on a decking panel. If necessary the bracketcan he slid along the panel a short distance to bring it into a more desirable between the right and left flanges thereof. In Fig. l a wide spacing is illustrated at 20 and a close spacing is illustrated at 2|. Regardless of the variations in spacing the springable and angular character of the right arm 9 of my bracket is operative to securely support the right end of the bracket.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
l. A bracket for attachment to deck'panels having U-shaped cross sectionwith interlocking rims on the bottoms of the flanges thereof, said bracket comprising, a generally U-shaped stamping having one arm extending perpendicularly with respect to the base of the stamping and another arm extending angularly outwardly from the perpendicular to the base of the stamping, said angularly disposed arm and base being relatively springable, an outturned flange on the end of said first arm, a hook on theend of said flange adapted to embrace the interlocking rims of two of said panels, stiffening flanges turned upwardly on the sides of said base, said base having a longitudinally extending slot formed therethrough, and a fixture anchoring plate fitting between said stiffening flanges and forming a plurality of tapped apertures registering with said slot, said other arm being substantially shorter than said perpendicular arm by an amount approximately equal to the thickness of the hook on said perpendicular arm.
' 2.

4. A bracket for attachment to deck panels having U-shaped cross section with interlocking rims on the bottoms of the flanges thereof, said bracket comprising, a generally U-shaped strip of metal having a pair of arms extending from the base of the strip, one of said arms extending angularly outwardly from the perpendicular to the base, said angularl disposed arm and base being relatively springable, an outturned flange on the end of the other of said arms, and a hook on the end of said flange adapted to embrace the interlocking portions of two of said panels, said one arm being substantially shorter than said other arm.
5. A bracket comprising a generally U-shaped body having one arm extending perpendicularly with respect to the base of the body and another arm extending angularly outwardly from the perpendicular to the base, said angularly disposed arm and base being relatively springable, an outturned flange on the end of said first arm, an upwardly and inwardly turned hook on the end of said flange, and stifiening flanges turned upwardly on the sides of said base, said base having a 1ongitudinally extending slot formed therethrough, said other arm being substantially shorter than said perpendicular arm by an amount approximately equal to the thickness of the hook on said flange.
6. A bracket comprising a generally U-shaped stamping having one arm extending perpendicularly with respect to the base of the stamping and another arm extending angularly outwardly from the perpendicular to the base of the stamping, said angularly disposed arm and base being relatively springable, an outturned flange on the end of said first arm, an upwardly and inwardly turned hook on the end of said flange, and stiffening flanges turned upwardly on the sides of said base, said base having a longitudinally extending slot iormed therethrough, said other arm being substantially shorter than said perpendicular arm.
7. A bracket comprising, a generally U-shaped body having a pair of arms extending from the base of the body, one of said arms extending angularly outwardly from the perpendicular to the base, said, angularly disposed arm and base being relatively springable, an outturned flange on the end of the other of said arms, and an upwardly and inwardly turned hook on the end of said flange, said base having a longitudinally extending slot formed therethrough, said one arm being substantially shorter than said other arm.
