ALONZO W. OLDS, OF GREEN OAK, MICHIGAN.

FRUIT-LADDER.

To all whom #may concern:

Be it known that I, ALONZO W. OLDS, of Green Oak, in the county of Livingston and State of Michigan, have invented new and useful Improvements in Ladders; and I do hereby declare that the following is a full and complete description of the construction and operation of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a perspective view. Fig. 2 is a detached part, and Fig. 3 is a side elevation, showing two different positions of the ladder.

Like letters refer to like parts in the several views.

I construct my ladder with three bars, A B O, of any desired length. These are supplied with rounds, D D D, placed at suitable distances apart for easy ascent, each round passing through each of the bars. Near the 10p of the bars A O, I afx a rotating hinge, shown detached at E, Fig. 2, an enlarged view of the hinge being shown at E. Oompound braces F G are secured to this hinge by a pin, F', formin g thus a kind of universal joint, for the brace, by the action of the hinge, can be turned in any direction. The bar F is secured to the bar G by a pin, G', upon which it can be turned, and the bar G is held in contact with the bar F by another pin, g, which can be removed, when the bar G can be laid horizontal, and this will bring the end ofthe brace F into contact with the ground and thus shorten the brace, or the bar G can be turned entirely around, so as to bring the end that is now shown as being upward to the ground, where it can be secured by the pin g, thus lengthening the brace, and in this way the diii'erent altitudes of the bars or ladder A B O can be accommodated.

An adjustable staging or platform is shown at H. This is supported by two rods, I J,

and end-pieces, K L. The rod J is in front of the ladder and the rod I behind it. Ihe rod J passes through the end-pieces, K, to both of which it is firmly secured. The pieces K are on the outside of the bars A O. The back end of these end pieces are provided with a slot, I', through which the rod I passes. A pin, i, is placed behind the rod I at different points to regulate the distance between the rods I and J. If the ladder stands nearly vertical, as in Fig. 3, the rod I should be secured in the forward part of the slot, which will make the distance between the two rods just sufficient to bring the platform H into a horizontal position, as shown in the figure, for the rod J will rest upon the front side of the ladder. If the ladder is more inclined, as in the dotted lines in Fig. 8, the pin lmust be moved back in the slot, so as to increase the space between the bars I and J, when the platform will still remain in a horizontal position, and in this manner, by moving the pin '5, the platform can be kept in a horizontal position, whatever may be the angle of the ladder. With this arrangement of parts the platform can be moved up and down, and secured at any desired elevation, with no other support except the bars A B C, and the greater the pressure upon the platform the firmer is its adherence to the bars; but, for the purpose of rendering the platform still more secure, I introduce a pin, N, below the rod J, into holes in the bar B, at the required height.

By removing the pin N and lifting upon the front side of the platform, it becomes released, and can be raised or lowered at pleasure. For the convenience of this movement, I attach a cord or rope, M, to the. middle of the bar J, the cord passing over the top round of' the ladder. By gently pulling upon this cord the platform can be raised or lowered at pleasure. l

What I claim as my improvment, and desire to secure by Letters Patent, is-

1. The compound braces F G, in connec tion with the universal joint E, arranged and operating as and for the purpose specified.

2. Ihe platform H, rods I J, and endpieces K L, arranged and operating as set forth.
