I construct step-ladder sides of' two strips, A and B, fig. l, their width being greater' than ltheirthickness', the face ot the top strip A being horizontal, and .that of the bottom strip, B, vertical. The ends of' said strips being joined, as shown in the drawing, with marine gine and screws, so as to make a permanent joint, thus making a strong and neat ladder side, withofthe city "vertical and lateral strength, with the least amount of material.
Figure 2 represents the face or top of the side. Figure 3 represent-s 'a cross-section of side eut at the point C.
Figure 4 represents-a ladder constructed with the above. described side, showing their connection with other parts of the ladder.
What l claim as new, and desire to secure by L'etters Patent, is-
The construction of step-ladder sides, of strips of wood 01 other material, the strips having a greater width than thickness, and the edge of one joined to the side of the other, thus fol-mingen angle, to give vertical and lateral strength with theY least amount of material, all substantially as eet forth.
