To all whom mag co iiccwt: Be it known that I, J oHNHUnENna citizen of-the UniteclStates, and a resident of vElizabeth, in the county of Union and State of New Jersey, United States of America, have invented a new and Improved Scaffold Bracket, of which the following is a full, clear, and exact description. 7

Objects of the present invention are to provide a scaffold bracket which may be readily attached to and detached from the wall of a building, a'bracket which is of simple, practical and rugged construction, which will be readily held'against side sway or wabble when hung, which is adjustable to various widths of studding, which can be folded so that it will occupy a very small space when not in use, and which may be manufactured with comparative economy.

A more specific object of the invention is to avoid the usual disadvantages of scaffoldbrackets formed of pipe sections with flattened ends, by equipping the ends of all of the bracket arms with malleable castings to eliminate breakage and distortion, and thereby prolong the life of the bracket.

With the above noted and other objects in view the invention consists in certain novel features of construction and combinations and'arrangements of parts, as will be more" fully hereinafter set forth and pointed out in the claim. The invention may be more fully understood from the following description in connection with the accompanying drawings, wherein- Fig. 1 is a perspective view of abracket in applied position. 7

Fig. 2 is an enlarged plan view showing the bracket folded.

Figs. 3 and fare sectional details on the lines 33 and 44 respectively of Fig. 1. Fig. 5 is an enlarged perspective view of a pair of associated castings.

Fig. 6 is an elevational detail showing the connection of the adjustable arms and the diagonal bracing member.

The bracket includes a pair of arms 10 preferably of flat steel stock having keyhole slots 11 in their upper ends, through which nails are adapted to be driven to support the bracket on the wall of a building. Arms 10 are slightly angular, so that their upper ends will be approximately parallel' when the two arms are spread to fully extended position. The lower ends of the arms are twisted as indicated: at, 12, and pivotally connected at-13 to the flattened 'end' 14 of a malleable casting j 1.5, which includes a usocketinto which the lower end of a diagonalrbracing arm 16 may be screwed. 'The twist in the lower ends of the arms 10 provides sufficient flexibility so that'their upper ends may be spread varying distances apart in accordance with the distance between studding in the walls to which the brackets may be attached.

The intermediate portions of brackets 17 straddle offset portions 18 in the upper ends of the arms 10, and are preferably riveted thereto as indicated in 19. Brackets 17 provide pairs of forwardly presented arms 20 between which the flattened ends 21 of castings22 are pivotally secured upon pins 23. The castings 22 are also formed with suitable threaded sockets for the reception of arms 24, adapted to be supported in horizontal position by the diagonal brace 16. It is upon the arms 24 that the planking or scaffolding is laid. 1. prefer to form the brace 16 and the arms 24 of steel pipe. The free end of one arm 24: issecured in a casting 25 similar to casting 22, and the free end of the'other arm 24E'is received in a socket 26 integral with a casting which includes a flat plate 27, having a slot 28 and hole 29 therein. The opening 29. is adapted to reglster with an openmg 30 in thecasting 25,

said aligned openings accommodating a bracket is apparent from Fig. 2 wherein it will be noted that the arms 2a have been disconnected from the diagonal brace by lifting the plate 27 ofl the shoulder 33. The arms 24 are then swung downwardly on their pivots 23. The brace 16 is swung upwardly on its pivot 13, and the flexibility of the twisted lower ends of the arms 10 permits their free ends to be moved together.

From the foregoing it will be evident that I have provided it bracket which is rigidly supported in applied position against side sway or wobble, which may he quickly applied or detached. and which is well adapted for withstanding the rough usi'ige to which it is ordinarily subjected.

The provision of the castings 15, 2, 25, and the casting which includes socket 26 and plate 27 greatly prolongs the lte oi the bracket. It has been heretofore customary,

simply to flat-ten the ends of the pipes which tonned the bracket arms. and pivotally eonneet such flattened ends together. with the result that breakage and distortion frequently occurred at the pivots.

lVhile I have illustrated a preferred embodiment of the invention, various slight changes and alterations might be made within the spirit and scope of the appended claim.

I claim:

A seaii'old bracket including a pair of horizontal tubular arms, castings formed with sockets into which the ends of the arms are screwed, supportingmembers adapted to be attached to a. wall means for pivotally connecting the castings at one end of the arms to the supporting members, means for pivotally connecting the 'astings at the free ends of the arms together, and means engageable with said connecting castings for supporting the arms in horizontz l position.

JOHN HUBENY.
