COMBINATION SCAFFOLD BRACKET.

Application mea June 23, 192e. serial No. 118,017.

This invention relates to a combination scaifold bracket of that class which is adapted to be supported from the side of a building and to serve as a support for one end of a plankl or planks to be used as a platform by a carpenter, painter, or other artisan.

The present., improvements relate more particularly/,to means whereby the supporting legs may be connected to diEerent points of the length of the horizontal bar; and to means on the bar comprising a novel adjustable attachment, enabling the bracket to be used as a window bracket and supported from the window stool and for the utilization of the barby the hanger or bail by which the legs aresupported from the horizontal bar, or, fory the use of the hanger or bail alone in connection therewith when the bar is engaged I with the studding. v Y

The present improved bracket is preferably l provided with a hook on the rear end of the horizontal bar to engage the studding `of the building when the bracket is used as a stud-r ding bracket. When this use of the bracket occurs, a part ofthe improvements, namely thel notches which are provided in the horizontal bar, are utilized by the bail ory hanger to maintain it iny locked position. YOn the other hand, when the bracket is Vused as a window bracket, the improved attachment is adapted to lock with any notch that is selected and to bear against the window stool, so that it is unnecessary to use the hook on the horizontal bar. When the hook isused to engage a piece of studding, the attachment may be takenfoif or disengaged from the notches as 4`it is thennot needed.

, rThe horizontal bar is provided with several holes which are used in connection with i0 the, bolt for attaching the legs to the bar, one

hole or another being employed for that purpose, according to the use to which theV bracket is put as, for instance. when it is used with a four-inch studding or a six-inch ,studding or in connection with the stool of a window; in which latter instance the improved attachment is used, being engaged with the window stool and locked by the Anotches in the bar;l g

The embodiment of the improvements en tering into the present invention hereinafter described, and shown in the accompanying drawings, has been found in practice to meet lall requirements of acombination scaffold bracket but I wish it understood that modifications may be resorted to without departing from the principle of the invention.

In the accompanying drawings:

Figure 1 is a perspective view of the bracket when used in connection witha fourinch 'studding Figure 2 is a similar view showing the bracket used as a window bracket.

Figure 3 is a side elevation illustrating the use of the bracket in connection with a four-inch studding.

Figure 4 is a side elevation of the bracket when used as a window bracket.

Figure 5 is a detail side view of the improved attachment.

Figure 6 is a detail plan view showing how the hook on the bar engages the'studding, and

Figure 7 is a detail plan view showing the Lise of the bracket in connection with a winc ow..

The bar 1 is the part of the'bracket which is disposed in general .horizontal position when the bracket is in use, this bar serving as a support for a plank or planks or platform on which the carpenter, painter, or other artisan stands when the bracket is applied to the studding, window stool, or side of the building o'r structure on which the bracket is used. Two or more of these brackets will be used to support the planks or platform.

The bar 1 is provided at its outer end with an upturned part or projection 2 which prevents the planks or platform from slipping off the end of the bar. At the inner end of the bar there isla hook 3 which is adapted to engage the studding of the building, such studding being shown at 4, if the bracket is used as a studding bracket. On the other hand, if the bracket is used as a window bracket, my improved attachment 5 is used and then is made to engage with the window stool 6 as will be more fully explained hereinafter.

The bar 1 has three holes 7, 8, 9 which are for the reception of a bolt 10 to connect the legs 11, 12 to the bar in one position or another, according to the use to which the bracket is put.

In Fig. 1 when the bracket is used as a studding bracket with a four-inch studding, the bolt 10 is entered in the hole 9. When the bracket isused with a six-inch studding, the bolt 10 is entered in the hole 8.

On the other hand, when the bracket is used as a widow bracket, the attachment 5 then engages the Window stool 6, and the outermost hole 7 receives the bolt 10.

1'he legs 11, 12 diverge from the point Where they are connected to the bar 1 by the bolt 10 to their lower ends where they are provided with feet 13. Preferably, these legs are ot angle iron :tor the purpose yot strength. Their divergence causes the bracket to be held in position with rigidity so that there is no substantial tendency to shift laterally. A cross'bar 11 of angle iron is secured to the legs 11, 12 in the region of the feet 13 and braces said legs.

A suspension bail or hanger 15 which, in the present instance, is an inverted V shaped rod, has its loop 16 straddling the bar 1 and its ends 17 bent, passed through holes 18 in the webs ot the legs, and bent down or clinched yas shown at 19. As the bail or hanger listraddles the bar 1, yit may assume different positions along said bar as illustrated, for instance, in Figs. 1, 2, 3, l. The hanger suspends the divergent lower ends oi the legs'11, 12 irom the bar so that there is no possibility of downward slippage o'lj' the legs and, `at the same time, there is au even distribution of the weight in respect to the two legs.

The upper edge of the bar 1 is provided with notches 2O oi a number suihcient to accommodate the attachment 5, according to vthewidth or thickness of the window stool 6 as shown in `Figs. 2 and 4, or to be utilized by the hanger or bail 15 as illustrated in Figs. 1 and 3.`

I am aware that the principle involved in the suspension of the legs 11, 12 by the hanger v 15 is not dependent on the employment of the one-piece V shaped hanger which is illusvtrated and I do not limit the invention to the particular form of hanger 15 which is shown and kdescribed as the legs may be suspended from the 'bar 1 in other ways in a bracket embodying my improvements. Modified forms of hangers for the legs 11, 12 may be provided with means to engage the notches 20.

My improved attachment 5 comprises an inverted L shapedor angular clamp having a cross pin, bolt, rivet, or member 21 which is adapted to drop into one of the notches 20 to secure said attachment in any one of several positions so that the attachment may be properly placed to cooperate with the inside of the window stool 6. The adjustment thus provided along the length ottl the rear end of bar 1 permits use of the'bracket in connection with window stools oi different depths. As

shown, the attachment 5 comprises two angular or L shaped pieces 5' which are spaced apart so that they may straddle the bar 1 and they have between them a piece 5b which is bolted or riveted thereto as shown at 22. The upper end of the piece 5* is rounded as `show-vn at 23 to lprovide the necessary clearance to enable the attachment to be :freely tilted when shifting the attachment along the bar 1 to position the cross piece, bolt or rivet 21 in the proper notch 20 so that the attachment may be located to engage the inner tace of the window stool 6. On the other hand, the reactionary pressure against the vertical part ,of the :attachment 5 causesthe member 21 to be held down in the notch and the squared or straight part 24 of the piece 5b to abut against the lower edge of the bar 1. The construction is such that the attachment 5 may be turned in one direction to release it but it cannot beturned in theother direction and it may also be entirely removed by slipping it along the lbar 1. For instance, in Figs. 1 and 3 Where the hook 3 is engaged with the studding, the attachment 5 appears although it is unnecessary and it is simply slipped along the bar 1 as shown by full lines in Figs. 1 and 3 to thus bein readiness for use when the bracket is used as a window bracket, or, the attachment 5 may be removed when the bracket is used as a` studding bracket.
