To all inkom-timely concern. y

'Be it known that'I, FREDERICK J. KESTNER,

a citizen of -the'United States, residingfat Cleveland, inv thecounty of Cuyahoga and State of" Gh'iO, have invented--certain new and u's'efullfmprovements in Scaold Brackets, of" which the follow-ing is lal specification.v

This invention relates to scaffold brackets,"

of that type which can be attached to the framing or-wall of abuilding for the" purposeof supportingi'a platformy in position for Workmen.- 'Ihefobjectof' the invention is to* provide an improved portable "bracket whichv can be folded' into smallVcompass, andi thereby easily transported and setup wheredesired.

A furthergolojectA of thel invention-is to provide an improved reversible. bracket7 which is capable of use under vvarious condi-y tions or in vario'us relations according to the brackets as willE `be` more fully apparent2 'as the description proceeds. I

l In the accompanying draWingsfF ig. l is a side elevation of the bracket attached to va Wall by nails or the like. Fig. 2 isa bottom plan view of thesame. Figt 3 isasimilar view with the bracketr folded; Fig. 4 is a side elevation of the bracket in reversed po' sition. Fig. 5 is a side view of the lbracket folded. Fig. 6 is a side elevation of a modi .3 tied dev-ice showing it used 1n one manner;

Fig. 7 is a similar view showing 1t used 1nv another manner; Fig. 8 is a fragmentary sectional side elevation showing another' means for attaching the same to a building; Fig. .9 is a plan view of the device as shown in Fig. 6; Fig. 10 is a plan view of the device in folded position; Fig. 11 is a side elevation of Fig. l0 and Fig. l2 is a detail of the ends of the members. Y

The bracket consists of three main members or arms, indicated at 6, 7 and 8. The arm or bar 6 in one position can be used as the supporting brace, as shown in Fig. 1, and in another position cank be used to support the planking or platform, as shown in Fig. l1,theparts 7 and 8 forming braces. Y

In the position shown in Figs. 1 and 2 the arm 6, which preferably consists of a straight bar of metal, is pivoted at 9 to the ears 10 of a Wall plate or fixture 11, which l can be attachedy tothe outside off a buildingf Wally as' by spikes -12.v At its outer vendthis r arm'is pivotedbya pin lS13-tothe outer ends of! thefpai'rofarms7fand 8,' the pin 13 being A loose andlongI enoughy to allow the arms 7 Vand 8 tospreadlaterally as well asswing vertically. Atl its outer extreniityf-the-arm 6 has afhook 1st-which iii-the other position ofv the/bracketmaybe used `,toAhook around'a` eacharm 7 and 8 is'pivotedas indicated!jat` 16, between'the ears'17 `of wall? plateI 18 whichisspiked'orfotherwise :fastened to a- Wall. Near the -r'ear' ends ithearms 7 and 8' are connectedby a .pair of transverse folding links l19.` The arms '7 andV 8 are furthermore cgnnected to the arm 6 by apair of hooked kro'd`s'20 which are hooked at 'one end as indicated at 21, in' -thefarms 7 and 8, and:y are hooked at theother end, asindicated at type of Wall or building on'whichthe bracket Q, is to belsupported.' f

A further-object ofthe invention is 'to generally improve the construction; of" such 22 in Sliding folded @up .01 ioop 23 which icapable of being slid lengthwisefonfthearmV 6, to'fold; or unfoldfthe members.L y

As stated,- the lbracket may beset 'up'withvl the arms 7? andv 8""at the top tosupportt'he plat-form '24, the armf6 acting'asa brace. Gr, the pivotal' connectionl of? the 8-can=befreversed so that' the armyv'can'sup'-l portthe platform, sis-indicated iny Fig. 4p For'thispurpose the pin orbolt"l3" is re- `moved'from-the-hold+25 through which=it Varms 7 andl and 5, whereby the arms 47 and 8 are swung together or toward each other beside the arm 6. This brings all the arms to. approximately parallel position both vertically fand laterally, and `folds the bracket into a small compass, convenient for transportation.. The loose or hooked connections between the v rods 20 and the loop 22 permit the rods to collapse toward each other between the bolt 13 also permits thearms 7 Vand to be 7 folded arms, and/the loose connection at the spread or collapsed as described.

For use vagainst a standing Wall the bracket may be spiked to the wall as shownr in Fig. 1, or by reversing the same, the hook 14 may be engaged around a stud, as shown in Fig. 4 with the wall plates at the ends of the arms 7 and 8 bearing against the-'wall to support the bracket. rlhis provides a very simple and convenient scaffold bracket for the intended purpose.' f

The modified form shown in Figs. 6 to 12 is much the saine as that above described with the exception of the following changes. The members G and 8 do not have the wall plates or xtures 11 and 18 on the ends thereof7 but instead the ends aie bent as shown in the drawings at 35 and 36 and have holes 37 therein from which extend the slots 28 so that the ends can be slipped over a nail which has been driven into the joists and can also be removed without pulling the nails. vThe member 6 is also adapted to be reversed for using the scaffolding in the different positions. rlhis is shown in Figs. 6 and 7 of the drawings.

When the device is'used it is necessary for the member 5 to be longer so it is provided with an extension of angle iron 29 riveted thereto and extending outwardly from the hook 14.. "On the opposite end of the member 6 is riveted a piece which will prevent the support or platforiil 2l from sliding over the end thereof.

It will be noted that the bent end of the member 8 liastwo bends therein; one at 35 and one at 31 so that it will get a bearing surface against the side of the house in whichever position it isA used either that w shown in Fig. 6 or, that shown in Fig. 7;

Fig 8 shows how the device may be used in the position shown in Fig. 7 without the use of nails. This is done by cutting a small hole 32 iii the wall andft'itltiiig the device and slipping the end 35 through said hole and letting it hook behind the wall.

as shown in Fig. 7 y

The member 6 will then rest against the outside of the wall. and the tie rod 2O will-hold it. The adjustable links'19` permit theniembers 8 to be nailed to studding at different distances apart, and in case there is a variation in the distance between the studs the members 19 will allow for this variation.

I claim:

1. A folding scaffold bracket comprising a single arm provided with a hook at one end, and a pair of bracearms loosely pivoted at one end to, said single arm, to swing vertically and laterally toward the single arm, the pivotal connection being adjustable to either end of said angle arm, a folding tie connecting the single arm and the pair of arms, and folding links connecting the brace arms, said tie being slidable along the single arm.

comprising a `single arm, a pair of brace arms, means to pivotally connect one end ofthe bracer arms to tlie'single arm near either end of the latter, anda folding tie connecting the single arm and the brace arms, i I

3.11 folding reversible scaffold bracket comprising a single arm, a pair of bracel arms, means to pivotally connect one end of the braceaims to the single arm near either endk of the latter, and a folding tie connecting the single arm and the brace arms, andl a. pair of folding links connected between the brace arms.

In testimony whereof, I afx inysignature.

in presence of two witnesses.

FREDERICK JL KESTNER.
