IMPROVEMENT IN APPARATUS FOR LOADING WAGONS.
Specification forming part of Letters Patent No. 179,972, dated July 18,1876; application filed June 20, 1876.
Similar letters 'of referenceindieate eorresponding parts.
My invention relates to that class of elevators which are used to raiseheavy articles for loading wagons; and it consists in a lever supported on suitable frame-work, to the shorter end of which a platform is suspended, and the longer end engages with a ratchet, the whole so arranged that a heavy article placed on the platform may be raised to the required height, when it will be retained by the ratchet.
A is a lever, having its fulcrum at a a in the posts B B. A plat-form, O, is suspended from a cross-bar, 0, which is attached to the short end of the lever A by the side pieces d (1. Guides 6 e are attached to the platform 0, and move in slots in the standards D D. Rollersf f are attached to the side pieces d d,
I which bear against the standards D D. A
ratchet bar or standard, E, is placed in such a position as to engage with the long end of the lever A, which is beveled on the under side to fit'the ratchet. A bar, F, is attached to the ratchet-bar E in such a way as to leave room between it and the ratchet-bar for the lever A and a spring, g, which is attached to the lever A, and bears against the bar E.
Any load placed on the platform 0 may be raised to the required height by forcing the long arm of the lever down. The spring 9 causes the lever A to engage with the ratchetbar, retaining the load.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of the lever A, platform 0, and ratchetbar E, substantially as shown and described.
2. The combination of the guides e 0, rollers f f, platform (hand standards D D, substantially as shown and described.
