Application filed December is, 1922. Serial no. 607,650.

To all whom z'tmay concern:

Be it known that I, WILLIE R. YOUNG, a,

This invention relates to improvements in scaffolds and it comprises a supporting member arranged for attachment to the wall of a building in proximity to a window, such member being provided with means for holding a a number bracket or the like in any one of of different vertical positions, a

bracket or the like arranged for temporary attachment to said member in one of the 1 positions,

and a collapsible platform arranged for attachment toa sill of a window of a building, such platform comprising .a

plurality be folded of connected members which may one upon another in such posltlon to provide a support in line with the bracket attached to the vertical member in one position and which may be unfolded and secured in unfolded position to provide a second support in al-inement with the first bracket or support connected to the vertical member in a second position, whereby a plank or the like may be used to bridge the space between the said platform and the bracket or support attached to the vertical member in their different positions; all as more fully hereinafter set forth and as claimed.

In the art to which this invention relates,

the provision of simple, inexpensive and easily handled scaffolding which may be tem orarily attached to a building without dis guring 'the same for washing the walls, painting washing the windows has 0 sideratum tion is the provision of such a scaffold.

, -In'the the purpose of the walls and ng been 'a de- One of the objects of'my invenaccompanying drawings I have my invention, in the several views of which similar reference numerals indicate corresponding Fig. 1 is a perspective view .0 a showlng my scafi'old applied thereto in one Q a member 12 which is provided at one end (the position parts. In the drawin s building Fig. 2 is a vertical segmental section view partly ,ln howing tion Fig. 3i

elevation through the. window the window support in one posis a view similarto Fig. showing the window support in the raised or elevated position; and

Fig. 4 is a detailed perspective segmentalview of the removable vertical wall support- 'inq member.

' in shape and having downwardly extending .slots 3 for the purpose of engaging the shank of the bracket hereinafter described. The sides of the wall sup orting members are also provided with a p urality of hooks 4 arranged for engagement with studs, nails or the like 5 which may be driven into the wall of the building.

The bracket designated as a whole by 6 (hereinafter referred to as the wall bracket) comprises two members 7 and SJarranged at approximately a 45 angle. The top member 7 is provided at its end with a locking portion comprising the square'head 9 and the shank 10, the head 9 being arranged for insertion in the square hole 2 of the wall supporting member so that the shank 10 may be lowered in the slot 3 of such member. When the wall bracket is secured in position in the wall supporting member as described, the member 7 of the wall bracket will extend outwardly from the wall of the building 'at substantially a right angle. The othermember 8 of the wall bracket will then be in position to engage the wall support at another lockin point,

this member 8 of the wall bracket being also provided withlocking means9 and 10.

Plank 11 may be sup orted atone end on the horizontal member of the wall bracket and on the other end now to be described.

The window bracket comprises a base by the window bracket,

end extending inside the room) with a clamp support on the window sill 17 and extends outwardly therefrom. It is, in addition to being supported inside the room by the clamp described, also braced by means of the brace designated as a whole by 1 8. This brace is hinged by means of the hinges 19 to the endof the base member 12 and the brace may comprise a plurality of arms hav ing att heir lower extremity a'squared blocklike member 20 which engages the outer face of the building; the whole construction being such as to rigidly hold the base member 12 against movement and vibration. The brace. 18 may be secured in bracing position by means of the hook 21 pivoted at 22 to the base member and hooking over stud 23 on the brace.

There is also attached to the base member 12 at its lower extremity, by means of the hinge 24, a foldable board 25 provided with a pivoted hook 26 and this board in turn is provided at its end with a hin e 27 car-' rying a second board 28 provide with the stud 29 over whichthe hook 26 may be placed. The second board 28 in turn 1S provided at its end with the hinge 30 and with the stud 31, the hinge 30 carrying a with the pivoted hook 33 arranged to engage the stud 31. These three boards just referred to may be unfolded and arranged in the form of a rectangle as shown in Fig. 3 so that the board 28 is elevated a considerable distance above the base member 12 and in such position' forms an elevated support for the end of the plank 11. When this collapsible platform arrangement is used in' the elevated position the wall bracket 6 may be attached in a corresponding elevated position on the wall supporting member. Theboards 25 and 32 may be of any length desired, but I have found in practice that if they be of a length sufiicient to elevate the board 28 about half 'way' up the window, not only can the entire window be washed by one standin on the board in its lowered and elevate position, but that the plank 11 when laced in these two positions makes the wal of the building accessible between two windows and thereby makes the entire wall of the building accessible because the.

window support ma be used on the next hi her or lower win ow.

'1 Tn order that the board 28 may be suitably braced when in elevated position, ll provide it with an eye 34 and I provide the base member with an eye 35. The detachable brace36 is angled at its ends and provided with the slots 37 and 38 arran ed to fit over the eyes 34 and 35. In e act this "brace 36"is a double hasp. The bolt or the like 39 may betemporarily in the eyes to hold the double hasp in position. The operation of the scafiold is obvious which wooden pegs may be driven to prea hinged member carried shown respectively in Figs. 3 and l, in,

which positions it serves as a support for one end of the board 11. Wall bracket 6 may be placed in any one of a plurality of positions on the wall supporting member 1'to accommodate the other end of the plank and washed or painted, all portions being .accessible through this arrangement.

The scafiold board 11 adjacent each end is provided with a series of openings 11, in

vent any sliding of the board on the wall scafiold and the window scafl'old.
