UNITED STATES JOHN WIRTH, OF NEW YORK, N. Y.

COMBINATION LADDER STEP AND SUPPORT.

Application filed January 4, 1927. Serial No. 158,944.

This invention relates to combination lad der steps and supports.

An object of the invention is to provide a device of this character which may be positioncd wherever desired along the length of a ladder, which will provide an extended step for the feet of the workman, which will function as a support for a. paint bucket or other articles, and which will also function to support the ladder.

A further object is to provide a device of this character which can be manufactured and sold at an extremely low price, which may be easily and quickly attached to a ladder, and which will most etliciently perform the functions for which it is intended.

lVith these and other objects in View, the invention consists in certainnovel features of construction and combinations and arrangements of parts, which will be more fully hereinafter described and pointed out in the claim.

In the accompanying drawings- Figure 1 is a fragmentary perspective view showing my improved step in operative position on the ladder;

Figure 2 is a view in verticalseotion showing my improved step in position to engage a building and support the ladder;

Figure 3 is a sectional plan view on the line 33 of Figure 2;

Figure 4 is a fragmentarysectional plan view illustrating a modification;

Figure 5 is a fragmentary view in section on the line 5-5 of Figure 4.

l, 1 represent the uprights or stiles of the ladder and 2 the rungs thereof. 3 represents my improved combined step and support, which consists preferably of a sheet of metal which may be of the required shape and which may be reinforced and strengthened in any desired manner to give the necessary rigidity thereto, but I have only illustrated my device as a plain sheet of metahand it to be understood that I do not limit myself in this respect.

The device 3 presents a straightedge 4 at one end, adapted to engage the wall of a building 5 and support the ladder at the proper inclination, although it is of course to be understood that this edge 4 may be otherwise shaped, as may be desired.

The device 3 is provided at its opposite edges with

recesses

6, 6 to receive the stiles 1 of the ladder, and the inner end of the metal sheet forming the device is bent downwardly CPI I flange 7.

at an angle forming a ladder-engaging This flange 7 and the walls of the recess 6 constitute a stile-engaging member which is rigid and which holds the step in position, as it will be noted that when the step is in operation, as shown in Figure 2, the tendency is to force the outer or free end of the step upwardly which serves to bind the step tightly against the stiles of the ladder, the intermediate portion of the step being supported upon the rung 2 of a ladder, so that the device as a whole is rigid and will effectually support a workman, giving him ample foot room, and can also support paint buckets, brushes, tools and other articles.

To further insure the positioning of the device on the ladder I provide the step 3 with upwardly projecting lugs 8 which are located against the faces of the stiles 1, and these lugs 8 are formed when the recesses 6 are formed, or, in other words, by cutting out these lugs and bending them upwardly the recesses 6 are formed, so that there is no loss of material. I of course secure the lugs against th stiles of the ladder in any approved manner but I have illustrated clamps 9 for this purpose. These clamps 9 comprise two angular members connected by bolts 10 and wing nuts 11 to clamp them around the stiles and around the lugs 8 effectually to secure the device against any movement on the ladder. In the modification illustrated in Figures 4 and 5, I provide the step 12 with laterally movable slides 13 at the inner portion of the ladder, mounted to move in grooves 14; and secured at any desired position of adjustment by means of bolts 15 which are projected through the slides and through slots 16 in the recessed portion of the ste and secured by nuts 17, as clearly indicate in Figures 4. and 5 of the drawings.

The device may be readily positioned on any rung of the ladder, and may be removed by disposing the same at an angle to the ladder so as to allow the device to be moved through the ladder between the rungs thereof, and it is of course to be understood that the recesses 6 are sufficiently wider than the width of the stiles to allow a free movement thereof.

Various changes and alterations might be made in the general form of the parts described without departing from my invention and hence I do not limit myself to the precise details set forth but consider myself at libert t0 make such changes and alteraadapted to receive the stiles of a ladder, said tions as airly fall within the spirit and scope In s adapted to rest against the stiles of the 10 of the appended claim. la der, and clamping means engaging said 1 claim: lugs, said plate at one end having a down- 5 A device of the character described, inwardly and inwardly bent flange engaging eluding ametal plate, lugs cut from the ends the faces of the stiles opposite to the taces of the plate and bent at an angle thereto engaged by the lugs. leaving recesses in the ends of the plate JOHN WIRTH.
