LADDER SUPPORT FOR HORIZONTAL TIMBER Filed Dec. 30, 1960 INVENTOR 1/4 fine/Paw I I BY I M ATTORNEY 6 United States Patent 3,020,973 LADDER SUPPORT FOR HORIZONTAL TIMBER William Howard Barrow, 803 N. 15th Ave., Laurel, Miss. Filed Dec. 30, 1960, Ser. No. 79,881 3 Claims. (Cl. 182214) This invention relates to a ladder support for a horizontal timber, and has as its primary object the provision of a devise adapted to be attached to the rungs of a ladder to which is secured a horizontal timber which provides a support against which the ladder leans, thus spacing the ladder from the side of a building or the like, and providing a supporting member for a block and tackle.

A further object of the invention is the provision of a device of this character which may thus be utilized for lifting materials to a roof, for example, from the ground, so as to render the lifting and handling of materials more rapid and easy.

A further object of the invention is the provision of such a device which may be attached to a ladder with a minimum of effort and difiiculty, and which will support the ladder in spaced relation to a building allowing space therebetween for the elevation of materials by a conventional block and tackle.

Still other objects reside in the combinations of elements, arrangements of parts, and features of construction, all as will be more fully pointed out hereinafter and disclosed in the accompanying drawing wherein there is shown a preferred embodiment of this inventive concept.

In the drawings:

FIGURE 1 is a perspective view of the device of the instant invention shown as attached to a ladder and hold ing a horizontal timber, the latter being supported as by sawhorse leg from the roof of the building.

FIGURE 2 is a perspective view of the device disassociated from the ladder, and

FIGURE 3 is a constructional detail, in section, showing the method of attaching the device to the rungs of a ladder.

Similar reference characters refer to similar Parts throughout the several views of the drawings.

Having reference now to the drawings in detail, the device of the instant invention is generally indicated at it), and is shown as mounted on a ladder L provided with the conventional rungs R. A horizontal timber T is shown in association with the device, the opposite end of which is supported on a sawhorse leg S which rests on a horizontal elevated surface H, such as a roof or the like.

The device of the instant invention comprises a horizontal plate 11, which is adapted to rest on a selected rung R of the ladder L, from the opposite ends of which depend spaced pairs of vertically disposed bars 12, the bars being of substantially identical length, and lying in a plane perpendicular to the plane of the plate 11. The bars 12 may be bent from an integral strip, having a bight 13, and secured as by welding 14, to the top of plate 11. The lower end of each bar 12 is provided with an opening 15, through which is adapted to extend a securing bolt 16. The openingin each pair of bars 12 are aligned, so that a bolt extending as shown in FIG. 3, will hold the device in position below the next lowermost rung, for example, to the rung which is supporting the plate 11. A wing nut 17 on each bolt serves to hold the device in related assembly.

Rings or eyes 18 are secured to the top of plate 11, in any desired manner as by welding, and have secured thereto chains 19 for lateral support of the device, the opposite ends of the chains being adapted to be secured to any desired supporting member.

Extending upwardly from the top of plate 11 are a "ice pair of vertically disposed parallel spaced apart members 20 which are integral with angularly disposed inclined members 21, the lower ends of members 21 being secured in any desired manner as by welding to the plate 11, or alternatively, comprising integral upturned portions thereof. The lower extremitiesof members 20 are secured in a relatively central position on the plate 11 as by means of welding 22.

It will be seen that in manufacturing the device the same may, if desired, be formed from three identical flat strips of suitable metallic material, one strip comprising the plate 11, the inclined portions 21, and the vertical portions 20, and the other two strips each comprising a pair of the bars 12 and their associated bights 13. Nail holes 23 may, if desired, be provided in horizontal members 20 for the securing of the end of the timber T therebetween.

In the use and operation of the device it will be seen in FIG. 1 that the ladder L is supported in spaced relation to the edge of the roof or horizontal surface H to permit space for the securement of a block and tackle assembly shown in dotted lines at B which is secured by a wire W or the like past about the timber T, the block and tackle being used for the lifting or raising of a bucket or container C, which may contain roofing material, or for any other desired similar purpose.

From the foregoing it will now be seen that there is herein provided a device which accomplishes all the objects of this invention, and others, including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative, and not in a limiting sense.

I claim:

1. A bracket for mounting a timber edgewise on a rung of a ladder comprised by a plate adapted to rest on the rung of the ladder, upwardly and inwardly inclined members united at their lower ends to the respective outer ends of said plate, parallel vertically disposed members positioned transversely of said plate and united at their upper ends to the upper ends of the upwardly and inwardly inclined members and at their lower ends secured to said plate, and pairs of parallel bars secured to said plate on its opposite sides adjacent the junctures with the upwardly and inwardly inclined members for receiving between the bars of each pair at least one lower rung of the ladder.

2. A bracket for mounting a timber edgewise on a rung of a ladder comprised by a plate adapted to rest on the rung of the ladder, upwardly and inwardly included members united at their lower ends to the respective outer ends of said plate, parallel vertically disposed members positioned transversely of said plate and united at their upper ends to the upper ends of the upwardly and inwardly inclined members and at their lower ends secured to said plate, rings secured to said plate adjacent the junctures with the upwardly and inwardly' inclined members, tensile members secured at one end in the respective rings for attachment at their other ends to fixed supports, and means for securing the plate on the ladder.

3. A bracket for mounting a timber edgewise on a rung of a ladder comprised by a plate adapted to rest on the rung of the ladder, upwardly and inwardly inclined members united at their lower ends to the respective outer ends of said plate, parallel vertically disposed members positioned transversely of said plate and united at their upper ends to the upper ends of the upwardly References Cited in the file of this patent UNITED STATES PATENTS Aldrich Apr. 30, 1861 Plass June 23, 1925 McKinney May 2, I944 Squire Mar. 29, 1955 Gerke Apr. 29, 1958 FOREIGN PATENTS France Oct. 5, 1936
