Vmessa PATENT OFFICE.,
JOHN s. HUNT, 0F RICHMOND, IHDIAHA.
IMPROVEMENT IN HCK'AND-LADDER APPARATUS.
Specification forming part of Letters Patent No. 128,882, dated July 9, 1872.
v two plans for locating and arranging the rollers, both of which are shown in the drawing.
Figure 1 is an end elevation of the compartments with the ladders inserted. Fig. 2 represents a cross-section of a ladder-rail, to which is attached a bearing in which rollers are held,
including the rollers and braces for supporting away. Fig. 3 represents a section, showing another plan of locating the rollers.
The parts b, d, and s constitute a frame, several of which are located at intervals along the length of the carriage, and are united, according to one plan, by ways u, upon which latter the rollers n play in running the ladders in and out, the Ways being supported by brace c e. The frames lthus compose the compartments. The parts al t represent the ladders. f
According to the plan represented in Figs. l and 2 the bearings fv are bolted to the inside of the rail, thus making the rollers a part of the ladder, pairs of said rollers being located at intervals along one rail of a ladder.
The other plan of locating Jche rollers, as shown in Fig. 3, consists in placing a roller, j, at the bottom of each compartment, over which the lower rail of the ladder runs in loading and unloading said ladders. This plan allows the brace c e to be dispensed with.
Having thus fully described my said invention, what Ic1ain1,and desire to secure by Letters Patent, is-
The vertical compartments, arranged to hold the ladders separately, with their breadths in a vertical position, substantially as described. JOHN S. HUNT.
