Patented Apr. 1, 1941 UNITED STATES PATENT OFFICE LADDER PLATFORM Emile Dubreuil, North Adams, Mass.

Application March 30, 1940, Serial No. 327,023

2 Claims.

My invention relates to a ladder platform and one of the objects of the invention is to provide a device of this character, which can be removably attached to a ladder, so that it can be supported on any rung of the ladder. Another object of the invention is to provide a platform of this character that will be substantially horizontal at the usual inclination of the ladder when in use.

A still further object is to provide a platform that can be cheaply assembled and will be efficient and safe in use.

With these general objects in view, my invention consists of certain novel and peculiar features of construction and combination of parts as hereinafter more particularly described and claimed and in order that it may be fully understood, reference is to be had to the accompanying drawing, in which Fig. 1 is an elevation of the ladder with the bracket attached;

Fig. 2 is a vertical transverse section of Fig. 1;

Fig. 3 is a section on the line 3-3 of Fig. 2, looking downwards.

The ladder is of the usual construction and has the legs I and rungs 2. The platform is constructed of a board 3 and may be fastened to the front brace 4 by screws 5 and is fastened to the rear brace 6 by means of a bolt I, that passes through the open slot 8 in the board 3 and through the hole 9 in the brace 6, a wing nut l0 engaging the screw threaded end of the bolt '1 for holding the parts in assembled position.

The front brace 4 is wider at the top H than at the bottom l2 and the back brace 6 is wider at the bottom l3 than at the top l4. The bevel of the braces is such that the platform will be substantially horizontal when clamped in position at the normal inclination of the ladder, when in use.

For securely clamping the platform in position, I provide bolts l5, with a head l6 and washer l1, that passes through holes in the front and rear braces, wing nuts I 8 engaging the screw threaded ends of the bolts l5 for securely clamping the platform in position.

In changing the platform from one position to another on the ladder, I loosen the nuts I8 on the bolts l5, loosen the nut ID on the bolt 9 and pull the back brace 6 out and then reassemble the platform at any desired position on the ladder. The platform, by virtue of this arrangement of parts will be securely held in position at all times.

From the above description, it will be apparent that I have produced a device of the character enumerated as desirable and while I have illustrated and described the preferred form of the invention, it will be understood that I reserve the right to all changes properly falling Within the spirit and scope of the appended claims.

Therefore what I claim as new and desire to secure by Letters Patent is:

1. A ladder having legs and connecting rungs, a front brace for engaging the legs of the ladder and being beveled and wider at the top than the bottom, a back brace for engaging the legs of the ladder and being complementary beveled and wider at the bottom than the top, a platform supported by said braces, means for securing the platform to the front brace, means for detachably securing the platform to the rear brace and comprising a vertical clamping bolt passing through a slot in the platform and through the rear brace.

2. A ladder having legs and connecting rungs, a front brace for engaging the legs of the ladder and being beveled and wider at the top than the bottom, a back brace for engaging the legs of the ladder. and being complementary beveled and wider at the bottom than the top, a platform supported by said braces, means for securing the platform to the front brace, means for detachably securing the platform to the rear brace and comprising a vertical clamping bolt passing through a slot in the platform and through the rear brace and horizontal clamping bolts passing through the front and rear braces and below the rungs of the ladder.
