1 Claim- (Cl. 248-210) This invention relates to afwork supporting bracket mountable on a step ladder.

An important object of this invention to provide an exceedingly simple attachment applicable in pairs to step ladders so as to utilize such ladders a the main supports for pieces of work, for example, for painting and cleaning Window screen frames, and the like.

The device is particularly well adapted to be used in conjunction with a ladder as an aid to support window screens for painting and repairing, because the same ladder that is used by a workman to obtain access to a screen to remove it is utilizable, when equipped with this device, to support the window screen in a position in which it can be conveniently worked upon as required. Without the use of the device it would be necessary to transport the screen, after removal from the window, to a more or less distant work bench.

A more specific object of the invention is to provide for application to ladders, and more particularly to step ladders, a simplified bracket consisting of a, one piece, elongated, rigid plate which can be securely attached to the ladder in several different adjusted positions so as better to adapt it for supporting different kind of objects to be worked on, and which, when not used to support work, can be attached to the ladder in a latched on fashion which safeguards it against being lost.

Other objects, advantages and features of invention will hereinafter appear.

Referring to the accompanying drawing, which illustrates a preferred embodiment of the invention,

Fig. 1 is a perspective view showing one of the brackets per se and on a larger scale than it appears in the remaining views.

Fig. 2 is a perspective view showing the invention applied to a single step ladder to support a window screen sash in an upstanding position.

Fig. 3 is a fragmentary. side elevation, on a larger scale than Fig. 2, showing one of the brackets mounted on the inner side of one of the legs of a step ladder in a position to support an upstanding screen frame or other frame while resting upon the bracket and leaning against the ladder, it being understood that the bracket shown has a mate cooperating therewith. Dotted lines indicate the position to which the bracket is adjusted when not in use.

Fig. 4 is a perspective view, on a somewhat smaller scale than Fig. 2, illustrating a screencarrying frame supported by and between two step ladders in a, position to be cleaned.

Fig. 5 is a fragmentary side elevation, on the same scale as Fig. 3, looking at the inner side of one of the legs of the ladder in the left hand portion of Fig. 4; illustrating how each of the paired brackets wil1 be positioned to support the work in the horizontal manner shown in the latter view.

Referring in detail to the drawing, the one piece bracket 1 which in the main forms the subject matter of this invention, consists of an elongated, strap-like plate of heavy, rigid sheet material having a pair of opposite recesses 8 in the edges of one end portion thereof, thus marking off a head 9 at that end of the bracket.

The bracket I also has through it, along its midwidth, a longitudinal slot In of the keyhole type, which is spaced considerably away from its said recesses 8 and which has its circular enlargement Illa in that end of the slot which is farthest from said recesses.

The aforesaid recesses 8 selectively cooperate with a headed screw l l which projects internally from the leg l2 of the step ladder l3 shown in Fig. 2 and in the left hand portion of Fig. 4, at about two feet above the lower end of said ladder, so that the bracketsrmay be horizontally supported by said screws either as shown in Fig. 3 or in Fig. 5.

With each already mentioned screw l I cooperates, at each side of the ladder, a second like screw I5 which projects internally from the same ladder leg, but which, when the ladder is in its upstanding position is located considerably forward of the screw II and slightly below the level thereof.

Each bracket 1 is provided, adjacent to that end portion thereof which is opposite to its head 9, with a spacious cut-out I! so located and contoured as to produce a, terminal hook or finger l8 projecting at a right angle from one side of the bracket. The inner end portion of said cut-out is shown beveled at H).

It will now be seen that, in order to support a window screen frame 20 in an upstanding somewhat inclined position as shown in Figs. 2 and 3, the workman may apply the brackets by so moving each bracket as to cause the head of the screw I 5 to pass through the brackets slot enlargement Illa while the bracket is positioned with its finger l8 directed upwardly and head 9 spaced downwardly from the other screw l I, and then, after sliding the bracket till the screw I5 abuts the opposite end of the slot l0, he may swing the bracket to its mounted position wherein the shank of the screw ll engages the upper recess 8. The brackets will thus be mounted in locked positions because the heads of the screws will prevent their displacement, and their upwardly projecting fingers I8 will efiectively hold in place the frame 20, the lower edge of which will rest in the bracket cut-outs l1.

It will now be obvious how to mount the brackets so as to support the frame 20 in the horizontal position shown in Figs. 4 and 5, a second ladder 2| being shown in the latter view to which also apair of the; brackets I is applied in the position illustrated in Fig. 5, in which position the bracket finger I8 are directed downwardly instead of upwardly so :as to present flat surfaces to the horizontally supported frame.

It is obvious that the slot ll] through the bracket may be variously contoured without departing from the spirit of the claimed. invention, the im-. portant thing being that it have one end portion wider than the other so as to receive. a. screw- 4 end for detachable and inverted sliding connection of the plate with a headed projection on a side of a ladder, said plate having a recess in one longitudinal edge forming a hook at one end of the plate, the opposite end portion of the plate having opposed transversely directed recesses for engagement with a second projection on the ladder.
