WAGON-JACK.

SPECIFICATION forming part of Letters Patent No. 296,979,`dated April l5, 1884.

Application filed February 18, 1884. (No model.)

To @ZZ whom t may concern:

Be it known that I, JOSEPH F. LINDsEY, a citizen of the United States, and a resident ot' Marion, in the county of Marion and State of 5 Ohio, have invented certain new and useful Improvements in Vagon-Jacks; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which formapart of this specification, and in which- Figure l is a side view of my improved wagon-jack as it appears when not in use. Fig. 2 is a similar View of the machine, showing it in its operative position. Fig. 3 is a perspective view. Fig. 4 is a cross-section through line :t x in Fig. 2, and Fig. 5 is a detail view of the cross-head at the lower end of the metallic stay or brace.

Similar letters of reference indicate corresponding parts in all the gures.

My invention has relation to wagon-jacks; and it consists in the detailed construction and combination of parts of the jack which will be hereinafter more fully described and claimed.

In the accompanying drawings, A A denote the parallel standards or uprights, which are bolted to opposite sides of the bottom sill, B. The lower part of the standards-A are notched on both sides, as shown at C, and their upper end is connected by a bolt in- 5 serted through the block I). A short distance under this block the standards are cut away to form openings E, which are recessed or countersunk on the outside to receive metallic plates F, the inner edge of said plates being cut into to form notches or bearings G. The notched plates F are of such a width as to leave a narrow slot or way, H, between their inner notched edges and the corresponding side of the opening E in the standard in which the plate is inserted.

I is the lever, which has a metallic shoe or bearing-plate, J, upon its short arm, and a bolt, K, having circular washers L and nuts M. This bolt is of such a size as to enable it to play readily up and down in the narrow slot H, from which it may be pushed into any one of the inclined notches or bearings G. To the under side of the long arm of the lever is fastened a rod, N, the free end of which terminates in a cross-head, O, which is wedgeshaped in cross-section, as will appear more clearly by reference to Fig. 5 of the drawings.

From the -foregoing description, taken in connection with the "drawings, the operation of my improved wagon-jack will readily be understood. The notches C in the sidestandards, A, being made with the continuations c, will hold the wedge-shaped cross-head O firmly in its position when it is wedged into its appropriate slot by the weight placed upon the short end of the lever, so that in shifting the jack from one side of the axle to the other, or

from one axle 'to the other, the brace-rod N will not become disengaged from the standards, but will maintain the leverin its proper position, unless the cross-head is purposely released by depressing the long arm or handle end of the lever.

Having thus described myinvention, I claim 2. rlhe combination, in awagonjack, ofthe parallel standards A A, having wedge-shaped notches Cc and notched bearing-plates F, lever I, having fulcrum-bolt K, and rod N, having the wedge-shaped cross-head O at its free end, adapted to be wedged into the notches C c and held in place therein, substantially as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
