A TTORNE YS DURWARD B. HAMPTON, OF NAIA, CALIFORNIA.

LADDER-STEP SUPPORT.

Specification of Letters Patent.

' Application filed December 24, 1919. Serial No. 347,136.

To all whom it may concern:

Be it known that I, DURWARD B. HAMP- TON, a citizen of the United States, residing at the city of Napa, in the county of Napa and State of California, have made a new and useful inventionto wit,lmprovements in Ladder-Step Supports; and I do hereby declare the following to be a full, clear, concise, and exact description of the same.

This invention relates particularly to metal supports for securing the ladder step to the ladder standards or side bars.

An object of the present improvement is to provide a cheap, simple and effective device, easily applied and combined with the ladder standard and step and which will provide a stable and rugged connection between the step and standard. A further obj ect consists in providing means for receiving a truss support extending beneath the full length of the step.

In this specification and the annexed drawings, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms, and it is also to be understood that in and by the claims following the description it is desired to cover the invention in whatsoever form it may be embodied.

In the accompanying one sheet of drawings,

Figure l is a perspective view of the metal support.

Fig. 2 is a perspective view of the same operatively applied to the step and standard of a ladder.

In detail the construction illustrated in the drawings comprises the flat, rectangular sheet of metal 1 having the upset bent-- over opposite ends 2 and 3 adapted to overhang and be secured to the opposite edges of the side bars or standards 4 of a stepladder of which a fragmentary detail is shown in Fig. 2.

The ends of the ladder step are each set in sockets formed by the integral, embossed projections 5 and 6 struck up from theplate 1 substantially cuneiform in cross section, and overhanging the upper and lower sides of the ends of the step 7 and held in proper horizontal alinement by the cross rod 8 passing through the hole 9 in the plate. The under side of the step 7 is provided with the longitudinal groove 10 in which the cross rod 8 lies to prevent lateral displacement of the step.

The projections 5 and 6, forming the step socket, are placed at a proper angle to the ends 2 and 3 formed on the plate 1, to hold the steps level when the ladder is inclined away from a vertical position. The step braces or supports may be cut and formed from an integral strip of sheet metal with the minimum of waste.

The step end adaptable to be seated Within the socket formed by the projections 5 and 6, is beveled parallel to the diverging or converging angle of the side standards.

Particular attention is directed to that feature of the construction whereby it is unnecessary to rabbet, groove or cut away any of the supporting standards to connect the steps thereto thereby retaining all ofdthe original strength in the side standar s..

In addition to the advantage of the simplified and economic manner of connecting the steps and standards, it also presents no projections or abutments likely to catch in the clothes of the user, or in the limbs of trees if the ladder is used for fruit picking. The structure is designed so that the mill work and assembly operations are simplified and at the same time provide maximum strength with a minimum weight of material.

Having thus described my invention what I claim and desire to secure by Letters Patent is 1. A ladder step support comprising a metal plate having a pair of parallel embossments, substantially cuneiform in cross section, formed integrally therein and forming a socket for receiving an end of a ladder step.

2. A ladder step support comprising a metal plate having a pair of parallel embossments, substantially cuneiform in cross section, formed integrally therein and forming a socket for receiving an end of a ladder step, and flanged ends adapted to engage the standards of a ladder.

3'. A ladder step support comprising a metal plate having a pair of parallel embossments, substantially cuneiform in cross section, formed integrally therein and forming a socket for receiving an end of a ladder step; flanged ends on said plate adapted to engage the side standard of a ladder and means secured to said step passing through Patented June 29, 1920.

said plate and standard for holding the said step and standard together.

4. A ladder step support comprising a metal plate having a pair of parallel embossments, substantially cuneiform in cross section, formed integrally therein and formiug a socket for receiving an end of a ladder step; a fastening bolt on said step passing through said plate and standard and means on said bolt for adjusting the position of said step end Within said socket embossments relative to the standard.

5. A ladder step support comprising a metal plate having a pair of parallel embossments, substantially cuneiform in cross section, formed integrally therein and forming a socket for receiving an end of a ladder step; flanged ends on said plate adapted to engage the side standard of a ladder; a fastening bolt on said step passing through said plate and standard and means on said belt for adjusting the position of said step
