6 claims-- (oi. 304-19 My invention relates to ladder and load supporting devices adapted for use in connection with painting or repairing buildings and the like and has as one of the principal objects thereof the provision of a devicev of the above described character which is adapted for use in connection with ordinary ladders of any size without modifying the same and which is so constructed and arranged as to maintain or support the ladder a desired distance away from the building and'at the same time support a load therebetween, forinstance a scafiolding, platform or the like.

Another object of my invention is to provide a device of the above described character which is simple in construction, durable in use, eiflcient in operation and economical in manufacture.

Other objects and advantages will be apparent from the following description, appended claims and annexed drawings.

Referring to the drawings wherein like reference characters designate like parts throughout the several views:

Figure l is a side elevation of my, invention illustrating the same as supporting a ladder adjacent the side of a building and supporting a work platform therebetween.

Figure 2 is a sectional View taken on the line 22 of Figure 1.

Figure 3 is a rear elevation of my invention illustrating the latter attached'to the upper section of a ladder.

Figure 4 is a side elevation 'of the inner end of one of the rods. 7 I

Figure 5 is a bottom. plan view of one of the rods on an enlarged scale.

Figure 6 is a front elevation of one of the braces.

Figure '7 is a bottom plan view of said brace.

In practicing my invention, as illustrated in the drawings, I provide a device 5 for supporting a ladder and load, for instance a platform- 1, adjacent the side of a building 8 whereby said platform may be utilized by workmen for painting or otherwise repairing said building. The device 5 comprises a pair of spaced diverging rods 9 having outer angled ends I 0, the latter being pointed whereby to enable the rods to firmly engage the side of the building.

The rods are also provided with inner angled ends ll integrally fashioned and braced with cufis l2 of a substantially rectangular configuration in plan and defined by side and end walls I3 and [4 respectively. The inner angled ends ID of the rods 9 are fashioned with subjacent loops or eyed sections l5 adjacent the cuffs'l2. Connected within said loops l5 are the hooked ends I6 ofb'race's II, the opposite ends of the latter being formed with angularly disposed eyed sections I8 arranged adjacent and in aligned relation with each other.

Both of the outer side-and end walls of the cuffs l2 have extending therethrough clamping screws or bolts IQ for engaging the upper ends of the side rails 28 of the ladder 6 and which upper I ends extend through the cuffs and are clamped subjacent the platform I for supporting the ladder.

Obviously, the supporting device 5 serves to support the ladder adjacent the sidesof a building and at the same time supports the platform 7. When a pair or more of said devices are utilized in connection with a like number of ladders the platform is supported in horizontality with respect to the building. In instances where it is only desired to raise and lower various objects, it is necessary to utilize only one ladder and one device. When one or more devices are thus utilized the weight of the load on the respective assemblies 23 is centralized between the rails of the ladder through the medium of the pulley block hook 2| being connected to the braces centrally between the rails of the ladder, thereby precluding lateral distribution of the weight with respect to the ladder and resultant overturning or displacement of the ladder.

It is obvious that the invention is not confined to the herein described use therefor as it may be utilized for any purpose to which it is adaptable. It is therefore to be distinctly understood that the invention is not limited to the specific construction as illustrated and described, as the same is only illustrative of the principles of operation, which are capable of extended application in advance forms, and that the invention comprehends allconstruction within the scope of the appended claims.

What I claim is:

1. In combination with a ladder having side rails and adapted to be supported adjacent ,a building, a supporting device comprising-a pair of diverging bars having outer angled ends for engagement with the building and inner angled ends formed with cuffs adjustably receiving said side rails, andbraces having ends detachably connected to said inner angled ends adjacent said cufis and opposite ends disposed adjacent each other and adapted for connection with the supporting member of a pulley block to connect said opposite ends of said braces together centrally between said rails.

2. A ladder and load supporting device comprising a pair of diverging bars having outer angled ends for engagement with a building and inner angled ends formed with cufis for receiving therethrough side rails of a ladder, and braces having ends detachably connected to said inner angled ends adjacent said cuffs and opposite ends disposed adjacent each other and adapted for connection with the supporting member of a pulley block to connect said oppositeends of said ably receiving the side rails of the ladder, said inner angled ends fashioned with loops adjacent said cufis, and braces having hooked ends connected to said loops and opposite ends disposed adjacent each other and formed with eyes for receiving the supporting member of a pulley block to connect said opposite ends of said braces together centrally between said rails.

4. The elements of claim 1 as set forth and defined therein including, means carried by said cuffs for clamping said rails in adjusted positions within said cufis.

5. The elements of claim 2 as set forth and defined therein including, means carried by said cuffs for clamping said rails in adjusted positions Within said cufis. I

6. The elements of claim 3 as set forth and defined therein including, means carried by said cufis for clamping said rails in adjusted positions within said cuffs.
