ADJUSTABLE LADDER-SHELF.

Specification of Letters Iatent.

Patented Mar. 26, 1918.

Application filed November 12, 1917. Serial No. 201,528.

To all whom it may concern:

Be it known that I, BERT O. Dorms, a citizen of the United States, residing at Woodland, in the county of Yolo and State of California, have invented certain new and useful Improvements in Adjustable Ladder- Shelves, of which the following is a specification.

This invention relates to an improved ladder shelf and the principal object of the invention is to provide a shelf which may be connected with a ladder and which may be adjusted so that the shelf will at all times be level without respect to the inclination of the ladder.

Another object of the invention is to so construct the shelf that it may be adjusted transversely of the ladder to extend either directly from the ladder or to one side thereo 1 Another object of the invention is to so construct this shelf that the bracket thereof may be easily and quickly connected with the rungs of the ladder and securely held in place when connected with the ladder.

Another object of the invention is to so construct this shelf that it will be held againstside play and thus danger of tilting prevented.

This invention is illustrated in the accompanying drawings, wherein Figure 1 is a view in elevation showing the improved bracket connected with a ladder,

Fig. 2 is a view showingthe improved bracket in side elevation and the ladder in section,

Fig; 3 is a vertical sectional view taken along the line 33 of Fig. 2,

Fig. 4 is a vertical sectional view taken along the line 4-4 of Fig.3 withcertain other portions of the bracket in place,

Fig. 5 is a fragmentary sectional view taken along the line 55 of Fig. 4.

This shelf is for use in connection with a ladder indicated in general by the numeral and will be suspended from one of the rungs 11 by the hooks or suspending rods 12, the upper or hooked ends of which engage one rung and the lower end portions of which will rest upon a lower rung. Sleeves or extensions 13 fit upon the lower end portions of these rods 12 and are held in a set position by the set screws 14, the sleevesbeing provided so that the rods may be lengthened if the device is used upon a laddeuhaw ing the rungs set far apart. These rods or hooks 12 are connected with the back-board or body 15 of the shelf by brackets 16 and at the lower end of the back-board there is provided a bracing rod or hook 17 pivotally connected with the body by the bearings 18 and having its hooked end portion 19 adjustably and releasably held in a set position by the set screw 20. This bracing hook may be swung to either side of the shelf and when in an operative position as shown in Fig. 1, will rest upon one of the hooks 21. By providing an adjustable mounting for this bracing hook 17 the hook may be turned in the proper direction according to the inclination of the ladder and thus the brackets prevented from having transverse movement upon the ladder.

A bracket plate 22 is pivotally connected with the body or base-board 15 by the pivot pin or bolt 23 and carries a housing 24 in which is slidably mounted a latching pin 25 yieldably held to extend through openings formed in the latch plate 26 by the springs 27. It will-thus be seen that this bracket plate may be turned to extend at the desired angle and may be releasably locked in the adjusted position. Upper and lower sets of

hinge ears

28 and 29 extend from the bracket plate 22 and serve to pivotally mount the rack 30, the rack being provided with

hinge cars

31 and 32 extending be tween the

hinge ears

28 and 29 and pro vided at its lower end with a hinge element 33. A pivot pin 34 connects the hinge ears 31 with the hinge ears 28 and a pivot pin or rod 35 of greater length than the rod 34 connects the ears of the hinge element 32 with the hinge cars 29 and extends down to pass through the hinge ears of the hinge element 33 and also extends upwardly through a latch plate 36. This latch plate 36 extends into a slot formed in the lower portion of the latch housing 37 and is provided with openings to receive the latching pin 38 slidably mounted is the housing 37 and yieldably held to extend through the rack plate 36 by a spring 39. Thisrack 30 can therefore be turned and releasably held in an adjusted position for a purpose to be hereinafter brought out. A lever or bar 40 is pivotally connected with the hinge element 32 and has arms 41 extending therefrom to support a platform or shelf 42. A latching pawl $3 for the lever or bar 40 is slidably mounted thereon, and extends to engage the teeth of the double rack 30 so that this latch lever may be releasably held in an adgusted position. An actuating pm at is connectcd with this pawl 43 and carries a spring 45 yieldably holding the pawl in engagement with the rack.

When in use, the bracket shelf will be connected with the ladder as shown in Figs. 1 and 2 and after the ladder has been put in place, the plate 22 will be turned to the vertical position and releasably locked. llhe latch lever or bar 40 will then be moved to bring the platform or shelt' 4-2 to a horizontal position so that articles placed thereon will not have a tendency to slide off and after this has been done, the latch 38 may be released and the bracket or rack member 30 may then be swung to one side and the latch 38 then released to lock the bracket in this position. It will thus be seen that the bracket shelf may be adjusted for the inclination of the ladder in case the ladder does not rest upon level ground and after the bracket has been brought to extend vertically, the shelf may be moved to ex: tend horizontally thus providing a steady support for any article which it may be desired to place upon the shelf. It will be further seen, that this shelf may be retained either in the position shown in Figs.

1 or 2 or it may be turned to one side of the ladder where it will be out of the way.
