Application filed March '29, 1917. Serial No. 158,360.

To all whom z'tmay concern: I Y

Be it known that .I, ARTHUnQCoNNoR, a citizen of the United States, residingat W'estgate, in the county of'Fayette, State of Iowa, have invented a new and useful Shelf for Ladders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the artto which it appertains to make and use the same.

The invention is a shelf for ladders and seeks to provide, as one of its objects, a shelf that can be hung conveniently onthe side of a ladder out of the wayof the workmen.

A further object is to provide, in such a shelf, means for attaching it at the back of a ladder also.

A still further object is to provide means for rigidly supporting the shelf when it is hung on the back of the ladder.

A still further object is to make the rigid supporting means adjustable, so that the shelf may be maintained in a horizontal position with various angles of inclination of the ladder.

Other objects will appear from the detailed description which follows.

In illustrating this invention, a particular design has been adhered to but the invention is not to be confined to this especial design. The right is reserved to make any changes or alterations compatible with the appended claims.

The same numerals of reference designate the same parts throughout the several figures of the drawings, wherein:

Figure 1 is a perspective view of the invention, showing it on the side of a ladder.

Fig. 2 is a side elevation of a portion of a ladder with the invention aflixed to the back thereof.

Fig. 3 is a sectional view, taken back of one of the supports of the shelf, to show clearly the manner in which the shelf is attached to the rungs of the ladder.

Fig. 4 is a section on the line 4-4 of Fig. l.

The invention is shown attached to a conventional ladder composed of the legs 1 and rungs 2. The invention itself comprises the substantially Z-shaped hangers comprising the upright parts 3, the upper horizontal parts 11, and the lower horizontal parts 8. Secured to the lower horizontal parts is a shelf board 4, and to the upright parts a back 5 is attached by screws, 6.v A bracing rod 7 is attached between the uprightparts 3, of the hangers and has its ends suitably fixed in said upright parts, and acts as a spacing brace between the two.

The lower horizontal parts 8 of the hang ers 3 have enlargements 9 between which a rod 10 is suitably attached and acts 'asa' lower spacing brace. The upper horizontal parts 11 of the hangers 3 have the depending ends 12 between which and theupper ends of the braces 13 slots'15 ,areformed to permit the attachment of the hangers to the bar 14. The braces 13 are attached to the upper horlzontal parts 11 and to the upright parts 3 of the hangers by suitable rivets or. the like 16. i

The bar 14, at each end is provided with slots 19 in which the upper horizontal parts 11 engage,-the depending ends 12 abutting the bar on one faceand the upper ends of the braces 13 abutting this baron the other face. At its longitudinal center, the bar 14 is provided with a slot 17 for engagement with the rungs 2 of the ladder when the Fig. l, the slot 17 of the bar 14 being made to engage one of the rungs 2 of the ladder and the shelf is connected .to the bar 14 by having the upper horizontal parts 11 engage the end slots 19 thereof. The shelf is then ready to support a bucket or whatever else it may be desired to place upon it, the shelf and its contents being then conveniently placed at the side and out of the way of the Workman who may be on the ladder.

In case it is desired to place the shelf on the back of the ladder, it may be conveniently attached on the back, as shown in Figs. 2 and 3. The slots in the upper horizontal parts 11 (which previously engage the slots19 of the bar 14) are made to engage one of the rungs 2. The bar 14 is then inserted between the rod 10 and the bottom 4 and one of its depressions 18 is made to engage the rod 10, whereupon the end of the rod 14 is bent down so that its slot 19 can be made to engage the next lower rung of the ladder, the bar 14 and upper horizontal parts 11 being thus sprung apart by adjacent rungs 2 of the ladder.

lVhen the angle at which the ladder is inclined is changed, the shelf can be moved to bring its bottom A into a horizontal position by disconnecting the bar lt from the rung 2 andso arranging the bar (with respect to the rod 10), by bringing another depression 18 into engagement with the rod 10 that, when thebarla is again connected to the rang 2, the bottom e: will be heldina horizontal positi'on.

It will be seen further that, to hold the shelf bottom 4: always in a horizontal position, the point of engagement betweenthe bar 1% and rod 10 approaches tl e end-of the bar 1& as the angle at whiclrthe ladder inclines from the vertical increases.

What is claimed is: l

1. A shelf forladd'e-rs comprising substantially Z-shaped hangers, spacing bars connecting. the hangers, a shelf 'a=tt-acl1ed=b"etweenthehangers, and a bar having ace'i'rtrally disposed slot for engagement with {the rung of'the ladder and end slots adapted-to receive the end of the hangers.

2. A ladder shelf, adapted for attachment at the backcor sides of a ladder, comprising st'ibst'antially Z-shaped hangers, ash'elf attached between the hangers, a spacing rod attach'edbetween the hangers and at adis tance below the bottonrofth-e shelf, and a masses bar having a centrally disposed slot for engagement with the rung of a ladder, the bar further having two end slots adapted to receive the ends of the hangers and having a series of depressions between the central slot and one of the end slots, whereby the bar may be used as a means for attaching the shelf at the side-of or on the back of a ladder.

3. A shelf for ladoersoomprisingZ-shaped hangers, a shelfattachedtherebetween, and abar c'on-nectible to the end of the hangers to swingthe shell: on the side oi": ladder or to supportitzon the back thereof;

at. A shelf forladders comprising. Z=shaped hangers, a shelf attached therebetween, and abarconnectible to the ends of the hangers to. swing the shelfion the side of a ladder or to support itxonthebaek thereof, the bar having means whereby the shelf when s'iipported on the back of the ladder canv be made-to assume ahoriz'onta-l position irrespective of the angle of inclination of the ladder.
