WILLIAM C. ELLIS,. OF PATRIOT, INDIANA.
IMPROVEMENT IN LlFTlNG-JACKS.
Specification forming part of Letters Patent No. 127,968, dated June 18, 1872.
I, WILLIAM G. ELLIS, of Patriot, in the county of Switzerland and State of Indiana, have invented a Machine for Raising and Liftin g Heavy Articles, of which the following is a specification:
Nature and Object of the Invention.
My invention relates to a lever-power so arranged as to be applied to any article that one may desire to have raised, the same bein g simple in construction and easily handled, and can be so adjusted as to apply to articles on the ground or elevated.
The following is a description of the accompanying drawing: Figure 1 is a view of the machine, with lifting-post in working order. Fig. 2 is a view of the two uprights and lifting-posts, attached. Fig. 3 is a side view of of the machine, with liftingpost removed and chain attached instead, ready for raising from the ground, or so near it that the post cannot be placed under the article, and with catch reversed so as to catch on the lever instead of on the upright.
GeneralDescription.
in g through the uprights and the lever, which bolt forms also the fulcrum for the lever. To the end of the lever is attached an iron ring, (oblong in shape,) F, which hangs loose in the fastening. Between the two uprights A A is placed a movable post, B, fastened there by means of the two pins, one on each side of the uprights. This post will move up or down at pleasure, the upper end passing through the ring F, which catches in the notches on the same, holding it at the proper height to suit the object to be raised, the raising being done on the, top of this post by bearing down the lever, which raises up the lifting-post.
To raise any article from the ground, or so near it that the post cannot be placed under it, the same power can be readily used by removing the post, which is done by slipping off the ring at the top and removing the pin at the bottom, which will allow it to be entirely separated from the machine, and attach the chain J, by means of the hook, to the ring and fasten the chain atone end to the object to be raised; or the chain may be attached and leave the lifting-post in its place, if desired. Thus I can apply this power to any article on the ground, or elevated above the height of the machine. With this power one man can performthelaborofatleastten. Theslidingcatch E, placed at the side, is so arranged that the catches on the same will fasten in the staple G and hold the article raised at any desired height, and may be fastened at the lever and work through the staple on the upright, or reverse, and fasten at bottom of upright and work through staple on the lever, as convenience may require.
A lifting jack having two braced standards, A A, movable post B, operating-lever D, with ring E attached to its extremity, sliding catch F, and bale G, arranged as described.
