Application April 15, 1952, Serial No. 282,437

This invention relates to a ladder attachment and more particularly to a device for supporting paint buckets, brushes or other tools on a ladder rail,

In the drawing:

Figure 1 is a side view of the base or attaching plate.

Figure 2 is a side view of the base plate on an enlarged scale with the rail clampin members attached thereto;

Figure 3 is a view similar to Figure 2 but showing the device clamped to a ladder rail and between two of the rungs thereof;

Figure 4 is a detail view of one of the clamping members;

Figure 5 is a perspective view of the clamping member shown in Figure 4. v

Figure 6 is a side view of the base plate with the adjusting plate pivoted thereon;

Figure '7 is a side View in elevation of the device.

Figure 8 is a top plan View of the device.

Referring to the drawings, I2 represents a flat circular plate which is provided with a continuous circular row of aperture 35 adjacent its periphery. A second substantially semi-circular flat plate 3'5 of substantially the same radius as the plate 52 is pivotally attached to one side of the plate 12 by a pivot member 36, as clearly shown in Figure 6. The plate 31 is adapted to be held in the desired position on the plate l2 by the engagement of the locking members 38 with certain of the apertures 35 in the plate I2.

The clamping means used to clamp the device on a ladder rail comprises two jaws l5 and i5 pivotally attached to the other side of the plate l2 by hinge members each of which comprises a pair of plates ll and 2t pivotally connected together at I9. The hinge plates are slotted at [8 and 26 so that the hinges may be adjustably connected to the plate l2 and the jaws I5 and 15. This adjustable feature allows the device to be mounted on ladder rails of differentcrosssectional dimensions. The plates H are secured to the plate l2 by the bolts I4, while the plates 20 are connected to the jaws by the bolts iii. A plate 22 pivotally connected to one edge of the jaw I5 by the hinge 23 is adapted to lie flat against a side of a ladder rail and at one edge adjustably carries a latch member made up of the plate 26, the bolt 28, and the nut 29. The bolt 28 is pivotally connected to the plate 26- by a conventional hinge 27. The inner end portion 33 of the nut 29 is reduced to fit into an obliquely arranged recess 3| formed in a keeper plate 30 secured to the outer face of the jaw I5 so that when the nut 29 i tightened the two jaws 2 Claims. (01. 248-210) will be brought into clamping engagement with the ladder rail. The plate 26- is slotted at 25 to receive a bolt 24 for adjustably mounting the plate 26 on the plate 22.

A container 40 is detachably connected to the semi-circular plate by th screws 39 carried by this plate and passin through openings formed in the adjacent end wall of the container.

As shown in Figure 3, the attachment may be secured to one of the faces of a ladder rail H by swinging the jaw members l5 and I5 into substantially parallel relation after which the plate 22 is swung over the rail with the portion 33 of the nut 29 engaging in the recess 3|. The nut 29 is then tightened to securely clamp the jaws on the rail l I between the rungs l0.

Having thus shown and described my invention, I claim:

1. A supporting attachment for use on a ladder comprising a circular flat plate adapted to be secured against the side of a ladder rail, said plate being provided with a circular series of apertures adjacent its periphery, a substantially semi-circular flat plate of substantially the same radius as the first-mentioned plate, said secondmentioned plate engaging and being pivoted to the first-mentioned plate, substantially diametrically disposed locking members mounted on said second-mentioned plate and adapted to be selectively engaged in certain of the apertures in said first-mentioned plate, a container having a side wall, means to detachably secure said container to said second-mentioned plate, said means comprising screws on said second-mentioned plate extending through openings in the side wall of said container, a pair of substantially parallel elongated clamping plates hinged to the first-mentioned plate and adapted to receive a ladder rail between them, means to adjustably secure one edge of said clamping plates on said first-mentioned plate, a plate member pivoted to the opposite edge of one of said clamping plates,

a laterally extending projection on the other clamping plate, an outwardly-opening recess in said projection, and a latch bolt on said plate member for engagement in said recess.

2. A supporting attachment for use on a ladder comprising a flat plate adapted to be secured against the side of a ladder rail, said plate being provided with a circular series of apertures, a second flat plate engaging and being pivoted to said first-mentioned plate, spaced locking memmeans to detachably secure said container to said References Cited in the file of this patent second-mentioned plate, a pair of rectangular UNITED STATES PATENTS substantially parallel clamping plates, hinges connecting one edge of each of said clamping ggz ggfi Dec f 1899 plates to the first-mentioned plate, a latch plate 5 831375 Polak Sept 1906 pimtany cmnected the edge 1,211j906 A1bert1fi Jan. 911917 clamping plate and carrying a latch bolt, and a 1243732 Goss et a1 Oct 23, 1917 keeper plate secured adjacent to the free edge 1,339,025 Garst May 4, 1920 of said other clamping plate and having a recess 10 1,353,277 Bochard 9 1920 to receive said latch bolt. 1,662,539 Schmidt Mar, 13, 1928
